Importance of Organic Food for a Healthy Lifestyle

healthy lifestyle
November 28, 2022 0 Comments


Always one element should balance in our body, if it increases or decreases leads to illness, that prime element is nothing but “Heat”.
We should choose our diet based on our body condition, environment & lifestyle; Whatever you eat should balance the heat in your body to lead a healthy lifestyle.
Nowadays, one word is very trending in this digital world of health consciousness, which is none other than “Organic”.
Many of us are not listening to it, few of us only will see what is organic? Why it is essential? Why it is insisted continuously?
We don’t have a choice, to explain the need for organic food, we need to talk about “The green revolution”, We are not fully against it but it seems we missed to address a few critical points during the implementation process of the green revolution, it was not properly forecasted about the cause & effect of the future generations, it is my opinion, it may be right or wrong, experts should answer.
Before 1960’s, In Pre-Green Revolution Era, the word “Organic farming” does not exist because every thing was made organically & naturally for eating and living a healthy lifestyle.
Green Revolution was a success formula on those days to meet the food demand of the nation but they concentrated only on quantity but not on quality of the product, they focused on productivity but missed to analyse the future impacts, We cannot blame them because situation pushed them to the corner to take harsh decisions, they were not in a position to think on health, they need some food for each and every citizen of India to live & survive, only thought was how to come out of food crises & how to feed a hunger on war foot basis.
After solving the food crises post 1960’s, further governments missed out to review the policies & impact of “The Green revolution”, that causes a heavy destruction now in our food culture & it affects the root of our food chains eco-system and it become a threat for our future generation kids.
After reading the complete blog, you will get some idea about the importance of organic food to safeguard our future generations…

Benefits of Organic food:

Benefits of Organic food

1. Helps cattle & human:

 In the ancient human civilization, cattle’s were merged with the human lives as a family member, people were living healthy on those days with more life span. Now a days with technology & medical advancements we are struggling to live a healthy lifestyle, think why? The simple answer is cattle, they give pure milk for your children to grow, they eat unwanted things in farm & give back healthy compost in return which will produce healthy food for human beings.

2. Good for nature: 

It reduces water consumption, improve soil fertility, reduces pollution, decrease soil erosion, it is good for all living beings nearby farms.

3. Self-sustaining resources: 

Organic farming is completely independent, it is based out of nature, it does not depend on outside world, so it can survive with its own resources in a cycle of nature, simply by living the normal natural life like in forest.

4. More nutrient value: 

Milk obtained from organic breeds having more nutrient value as per scientific research,
a. Organic milk is healthier comes down to its ratio of omega-6 to omega-3 fatty acids, which is lower than in regular milk. A diet containing too many omega-6 fatty acids and not enough omega-3s has been linked to heart disease, as well as cancer, inflammation and autoimmune diseases.
organic milk
b. Organic milk differs from conventional milk in three specific ways: it must come from cows that aren’t treated with antibiotics, it must come from cows that are not given any hormones for growth or reproduction, and it must come from cows that receive at least 30% of their diet from pasture.
c. All milk contains hormones (including growth hormone) that is naturally produced by the cow. So the key word to look for is “added.” Organic milk comes from cows that have never received added hormones of any type, ever.

5. No antibiotics to animals:

a. Food animals can carry bacteria, such as Salmonella and Campylobacter, that can make people ill. When animals are given antibiotics, resistant bacteria in their intestines can continue to survive and grow.
b. Antibiotic use can promote creation of superbugs which can contaminate meat and poultry and cause hard-to-cure disease in people. Superbugs can also exit the farm via farm workers, wind, runoff, and wildlife.
c. Antibiotic resistance: Understanding the connection to antibiotic use in animals raised for food. For both humans and animals, misusing and overusing antibiotics can lead to the development and spread of antibiotic-resistant bacteria. These may cause untreatable infections
d. In the digestive tract of cattle, and in cattle manure. Each of these changes may have drastic effects on a major ecological disservice: the release of methane (CH4) from cattle and their dung.
e. The use of antibiotics in food animals selects for bacteria resistant to antibiotics used in humans, and these might spread via the food to humans and cause human infection, hence the banning of growth-promoters. The actual danger seems small, and there might be disadvantages to human and to animal health.
f. There is an increasing amount of evidence suggesting that the sub-therapeutic use of antibiotics in food animals can pose a health risk to humans. If a group of animals is treated with a certain antibiotic over time, the bacteria living in those animals will become resistant to that drug.
g. The reason lies within animals’ guts. When animals frequently are treated with antibiotics, the bacteria inside their intestines dies. Antibiotic resistant bacteria is left behind—and it can run riot without other bacteria to fight it.

6. No growth hormone to animals:

a. The hormonal substances used for growth promotion in cattle are the naturally occurring steroids: estradiol-17β,progesterone, and testosterone, as well as synthetic compounds such as zeranol, which has high affinity for estrogen receptors, trenbolone acetate, which has affinity to androgen receptors, and melengestrol acetate, which has similar activity to progestins.

b. Estradiol:

i. Estradiol-17β, alone or in combination with other hormonally active substances, is administered to cattle by a subcutaneous implant, usually in the ear, to improve rates of weight gain and feed efficiency (Wagner, 1983) .The amount of estradiol benzoate treated per animal is 10~28 mg, which is equivalent to 8~24 mg of 17β-estradiol. The release rate from one type of commercial implant is approximately 60 μg per animal daily (JECFA, 2000b).
ii. Estradiol exerts its biological effects largely by binding with intracellular receptors, and in females it induces growth and development of the reproductive tract and breasts and the appearance of secondary sex characteristics after binding with the receptors.
iii. In general, orally administered estradiol is inactive because it is metabolized and conjugated in the gastrointestinal tract and liver (Moore et al., 1982) . Fine-particle formulations of estradiol given orally for contraception or hormone replacement therapy in menopausal women show bioavailability of 5% of that of a dose administered intravenously (Kuhnz et al., 1993) . Estrogen did not exert teratogenic effects in a human study of approximately 7,700 infants whose mothers took oral contraceptives while pregnant (Rothman and Louik, 1978) . Estradiol has genotoxic potential by inducing micronuclei, aneuploidy, and cell transformation in vitro,and oxidative damage to DNA and DNA single-strand breakage in vivo (IARC, 1979, 1999) . In long-term studies of carcinogenicity in mice and in rats, increased incidences of tumors were found in mammary and pituitary glands; the uterus, cervix, vagina, and testicles; and lymphoid organs and bone (IARC, 1979) . Malignant kidney tumors occurred in intact and castrated male hamsters and in ovariectomized female hamsters. IARC (1987) also concluded that estradiol-17β is a Group I human carcinogen that has sufficient evidences for carcinogenicity to humans. The carcinogenicity of estradiol is found to be a result of its interaction with hormonal receptors because tumors largely occur in tissues possessing high levels of hormone receptors. Overall, estradiol is evaluated as a genotoxic carcinogen, however, it is necessary to consider that estradiol is a natural hormone synthesized in the human body and used as a human medicine.
iv. JECFA (2000b) determined the NOAEL (No-observedadverse-effect level) of estradiol-17β as 5 μg/kg bw/day based on human epidemiological data rather than animal toxicity data. The value was calculated from 0.3 mg/day of estradiol administered orally to women (60 kg mean body weight) , which did not relieve any symptoms of menopause and there were no changes in serum concentrations of corticosteroid-binding globulin (CBG) . The ADI of 0~50 ng/kg bw/day was determined by dividing the NOAEL of 5 μg/kg bw/day with an uncertainty factor 100.
v. Estradiol-17β occurs naturally in all mammals. Background levels vary with the age and sex of each animal species. The highest natural levels are found in pregnant animals. The normal daily production of estradiol-17β is
vi. 6.5 μg in prepubertal boys, 48 μg in men, and 37.8 mg in pregnant women (Angsusingha et al., 1974) . Estradiol is used as a growth promoter in cattle and may produce twofold to several ten-fold increases in levels, reaching peaks in the liver and fat of steers and calves (Paris, et al., 2006) .The amounts of estradiol in the muscle tissue of treated veal calves, heifers, and steers were 11~280 ng/kg, whereas 3~35 ng/kg were detected in non-treatment groups. The intake amount of estradiol via the meat of treated animals (0.0045~0.180 μg per 500 g portion of meat) is approximately forty times to thousands of times lower than the amount of human daily production of the hormone (Table 2) . In addition,estradiol becomes inactivated when administered orally due to gastrointestinal and/or hepatic metabolic functions. JECFA (2000b) concluded that the amount of exogenous 17β-estradiol ingested via meat from treated cattle would be incapable of exerting any hormonal effects in human beings.
c. Since bioavailability is very low in the case of orally administered estradiol, and even when absorbed into the circulatory system, circulating estradiol is in the inactive form mainly bound to sex hormone-binding globulin (Fotherby,1996) . JECFA recommended that establishing MRLs is unnecessary because exogenous estradiol is structurally identical to that produced endogenously in human beings, showing great variation in levels according to age and sex (Table 3).

d. Progesterone

i. Progesterone is administered to cattle in combination with estradiol benzoate at a ten to one ratio (progesterone 100~200 mg with estradiol 10~20 mg) as an ear implant, to increase rates of weight gain and feed efficiency. Progesterone is also used to synchronize estrus in lactating and non-lactating dairy cows and goats via an intravaginal sponge. Exogenously administered progesterone is structurally identical to the progesterone produced in animals and humans. Progesterone is poorly absorbed by oral ingestion and inactivated in the gastrointestinal tract and/or liver, which makes its bioavailability less than 10%after oral administration (Simon et al., 1993) . Orally administered micronized progesterone for hormone replacement therapy in women reaches a peak plasma concentration within 4 h and returns to baseline by 6 h (Nahoul et al.,1993; Sitruk-Ware et al., 1987).
ii. The main function of progesterone is to regulate the female reproductive cycle for the preparation and maintenance of pregnancy in association with estrogens (JECFA,2000b) . Progesterone also induces increases of plasma cholesterol and low-density lipoprotein, decreases of high-density lipoprotein, and sodium excretion. The major metabolites found in plasma are pregnanediol 3a-glucuronide, 17-hydroprogesterone, and 20a-dihydroprogesterone. Most of the progesterone in blood is bound to CBG or albumin, where approximately 17% of serum progesterone is bound to CBG and 80% to albumin, and 2.5% is in the free form (Robinson et al., 1985).
iii. The amount of progesterone produced in the human body varies according to physiological status, such as 418 μg/day in premenopausal women in the follicular phase of the reproductive cycle, 94,000 μg/day during late pregnancy, and in post-pubertal men production is 416 μg/day (Table 2) (Galbraith, 2002).
iv. In humans, progestogens are mainly used for contraception and for hormone replacement therapy. The therapeutic dose of fine-particle progesterone is 400 mg/day for 10 days in women, and a dose of 300 mg/day for 10 days per month is well tolerable (JECFA, 2000b) . In a human study to explore the effects of oral micronized progesterone on endometrial maturation, healthy menopausal women orally given 300 mg/day micronized progesterone for 14 days after estrogen priming for 30 days showed incomplete conversion of the uterus to full secretory activity of uterus with significant increase of glandular glycogen by 124%. However, the group receiving 600 mg/day showed full secretory conversion of uterus with 291% increase of glandular glycogen. Nuclear estrogen receptor content in the stroma of the endometrium was decreased by both doses of progesterone, but the group given 300 mg/day did not reach significance (Kim et al., 1996).
v. In other human studies, post menopausal women were given 200 or 300 mg/day of progesterone orally for the last 14 days of percutaneous estradiol treatment of 1.5 or 3 mg/day for 21 of 28 days for one or five years. There was no evidence of endometrial hyperplasia or carcinoma after five years of estradiol and progesterone treatment (Moyer et al.,1993) . Oral fine-particle progesterone treatments of 200 or 300 mg/day in sixty women with oligomenorrhea or amenorrhoea showed effects of withdrawal bleeding with unchanged lipid concentrations (Shangold et al., 1991) . Furthermore, there were no adverse effects in women receiving 200 mg/day of fine-particle progesterone orally for hormone replacement therapy, which induced minor changes in plasma lipoprotein profiles in some subjects but not all, and no changes in haemostatic parameters (Sitruk-Ware et al., 1987) .
vi. In a study using female BALB/cfC3H/Crgl mice, 100 μg of progesterone was administered subcutaneously alone for five days beginning 36 h after birth causing ovary-dependent, persistent vaginal cornification and hyperplasia in the vaginal and cervical epithelia, and significantly higher incidence of mammary tumours in mammary tumour-virus bearing mice (Jones and Bern, 1977) . Progesterone increased the incidences of ovarian, uterine, and mammary tumours in mice as well as mammary gland tumours in dogs (IARC, 1979) , and these effects were regarded as hormone activity related. The IARC concluded that there is limited evidence for the carcinogenicity of progesterone in experimental animals and no evaluations of its carcinogenicity in humans can be made in the absence of epidemiological data (IARC,1979, 1987) . Progesterone has shown no evidence of genotoxicity (IARC, 1987; Seraj et al., 1996) . In addition, progesterone did not induce any adverse effects on fertility and development in rats and rhesus monkeys (Wharton and Scott, 1964) .
vii. In comparison studies for concentrations of progesterone in edible tissues from non-treated and treated veal calves,heifers, and steers, ranges of progesterone were not different between the groups; however, in the treated animals,amounts of progesterone in adipose tissue (3.20~8.66 μg/kg) were several times higher than amounts found in the control animals (0.87~1.60 μg/kg) (Table 2) (Paris et al.,2006). This increased amount is about a thousand times lower than daily production amount in adult men and women of normal status.
viii. For changes in the human uterus, JECFA established the ADI of progesterone as 0~30 μg/kg bw based on a LOAEL of 200 mg/day (equivalent to 3.3 mg/kg bw/day) . One-hundred as an uncertainty factor was allotted as 10 for extrapolation from the LOAEL to the NOAEL and 10 for individual variations. MRL was recommended to be unnecessary because it is identical to endogenous progesterone and the amount of estimated daily intake via food consumption is negligible comparing the level of daily production in human beings (JECFA, 2000b) (Table 3).

e. Testosterone

i. Testosterone propionate (200 mg) in combination with estradiol benzoate (20 mg) is administered to cattle as an ear implant for growth promotion. Orally administered testosterone is mainly inactivated during digestion and hepatic metabolism. The bioavailability of orally treated testosterone is approximately 3.6% of the administered dose. In an earlier study, the plasma half-life was 10 min after intravenous administration and about 90% of the administered dose was excreted into the urine (Tauber et al., 1986).
ii. Testosterone is synthesized in testicular Leydig cells, ovarian thecal cells, and the adrenal cortex, and it exerts activity via binding with androgen receptors. Testosterone is a precursor of other steroid hormones. The active metabolite of testosterone is dihydrotestosterone (DHT) , which is metabolized to androsterone, androstanedione, and 3α- and 3β-androstanediol. The physiological concentration of circulating testosterone is 3~10 ng/ml in men (Miyamoto et al., 1998). The major functions of testosterone are pubertal development for spermatogenesis, regulation of the differentiation of the prostate, stimulation of erythropoietin production in the kidney and stem cells of the haematopoietic system, and the acceleration of growth during puberty in conjunction with growth hormone.
iii. In a human study, 400 mg of fine-particle testosterone administered orally for 21 days was well tolerated without any significant side effects in healthy male volunteers (Johnsen et al., 1974, 1976) . Increases of prostate gland weight and volume as well as amounts of serum testosterone, DHT, androstenedione, and estradiol were found by intramuscular injections of 200 mg of testosterone enanthate (equivalent to 8 mg/kg bw) for 28 weeks in adult male baboons (Karr et al., 1984) . Many studies on genotoxicity have shown that testosterone alone has no genotoxic potential (Han et al., 1995; Ho and Roy, 1994; Lasne et al., 1990;Seraj et al., 1996; Tsutsui et al., 1995) . Testosterone (10 mg) induced resorption of embryos in female SD rats when it was treated subcutaneously on day 10 of gestation (Sarkar et al., 1986) . For the carcinogenic potential of testosterone, the IARC (1979) determined that it is reasonable, for practical purposes, to regard testosterone as if it presented a carcinogenic risk to humans due to an absence of adequate data in humans, but there is sufficient evidence for its carcinogenicity in experimental animals.
iv. In human medicine, testosterone is used to treat deficient testicular function in men, and to replace hormones in postmenopausal women in combination with estrogen (Sands and Studd, 1995) . Orally administered testosterone undecanotate induced the progression of virility and testicular growth, and the acceleration of growth associated with puberty in delayed boys at 40 mg per day for 15-21 months without any side-effects (Butler et al., 1992). In a human study with eunuchs, 25 and 100 mg of testosterone administered orally did not exert any effects; however, 400 mg exerted effects such as sexual desire, erection, ejaculation, and general well-being (Johnsen et al., 1974). In another study, oral administration of testosterone at 100 mg/day restored sexual function slightly (Foss and Camb, 1939).
v. JECFA (2000b) established the ADI of testosterone as 0~2 μg/kg bw based on a NOAEL of 100 mg/day (equivalent to 1.7 mg/kg bw/day) and an uncertainty factor of 1000 based on the study of eunuchs. Paris et al (2006) reported that the residue level of testosterone in muscle of implanted veal calves or heifers is 0.031~0.360 μg/kg, while that of non-treated animals is 0.006~0.029 μg/kg. When comparing the ADI value, the amount of testosterone via beef intake from hormone-treated animals is thousands of times lower than the ADI. The MRL of testosterone in beef is not necessary because of the same reasons for the cases of estradiol and progesterone (Table 3).

f. Zeranol, melengestrol, and trenbolone

i. Zeranol, melengestrol, and trenbolone are all synthetic xenobiotic growth promoters. Zeranol is a non-steroidal anabolic agent administered subcutaneously as an ear implant in cattle and shows estrogenic activity (Katzenellenbogen et al., 1979). Zeranol is metabolized to zearalenone and taleranol and tissue residue levels of zeranol are in the range of 0.01~1.21μg/kg with peak levels in liver tissue (Paris et al., 2006). Orally administered zeranol showed weak estrogenic effects in long-term toxicity studies using rats, dogs, and monkeys through changes in mammary glands and reproductive organs (Davis et al., 1977; Everett et al., 1987; Revuelta et al.,1997; WHO, 2000b) . Zeranol and its metabolites, zearalenone and taleranol, were negative in several in vitro and in vivo genotoxicity assays (Bartholomew and Ryan, 1980;Ingerowski, et al., 1981; Scheutwinkel et al., 1986; Williams, 1984) . In carcinogenicity studies of rats and mice, only the mice showed a higher incidence of tumors in the anterior lobe of the pituitary gland compared to a control group, but this effect was regarded as being due to the estrogenic properties of zeranol (Everett, et al., 1987; Gardner,1941; JECFA, 1988) . In an uterotropic assay using sexually immature rats, orally administered zeranol, zearalanone, and taleranol presented estrogenic potencies 1/150, 1/400,and 1/350 that of estradiol-17ß, respectively (Everett et al.,1987) . In ovariectomized female cynomolgus monkeys, zeranol given orally for 13 weeks induced the maturation of vaginal epithelial cells at 0.5 and 5 mg/kg bw/day, and the NOAEL was evaluated as 0.05 mg/kg bw/day based on the estrogenic effects of zeranol (JECFA, 1988). JECFA recommended its ADI to be 0~0.5 μg/kg bw/day by applying an uncertainty factor of 100 for interspecies and individual differences (JECFA, 1988). The MRLs are settled as 2 μ/kg for muscle and 10 μ/kg for liver in beef (Table 3).
ii. Melengestrol is a synthetic progestogen administered orally as a feed additive to improve feed efficiency. The approved feeding doses are in a range of 0.25~0.50 mg/heifer per day during the fattening and finishing periods (Neidert et al.,1990). Its activity is revealed via a high affinity for progesterone receptors as well as increases in prolactin secretion and the activation of estrogen receptors (Perry et al., 2005). Melengestrol acetate (MGA) was metabolized to 2β,15β-dihydroxy methyl MGA, 6-hydroxy methyl-MGA, 15β-hydroxy-MGA, and 2β-hydroxy MGA in a vitro system prepared from cattle, and the most active metabolite among them was 2β-hydroxy MGA showing 9-times less potency than MGA (WHO, 2004). The residue level found in Canadian beef heifers treated with MGA at a rate of 0.40 mg/animal per day during 1982~1984 was 2.8 pg/kg as a mean value (ranging < 2 to 28.7 pg/kg) , and 4.6% of all samples had MGA residues of more than 10.0 pg/kg of fat (Neidert et al., 1990).
changed menstrual cycles
iii. Melengestrol acetate was found to be a low acute toxic chemical in rodents after oral administration. Melengestrol acetate was not a genotoxic chemical in a full range of in vitro and in vivo assays, including bacterial and mammalian cellular gene mutation assays, unscheduled DNA synthesis assay, and micronuclei test in mice. In a tumor study,a higher incidence of mammary tumors was found in C3Han/f mice, but this was caused by the increased release of prolactin rather than direct action of MGA (JECFA,2000c). Orally administered MGA induced reproductive toxicity as impaired pregnancy and parturition and greater pup loss in beagle dogs, and the NOAEL for reproductive toxicity was set at 2 μg/kg bw/day (JECFA, 2000c; Lauderdale,1977). MGA exerted embryotoxic, fetotoxic, and teratogenic effects including resorption, dead fetuses, visceral malformation, and incomplete skeletal ossification in rabbits, in which the NOAEL was 0.4 mg/kg bw/day (JECFA,2000c). The most appropriate end-point for MGA is a progestational effect such as changed menstrual cycles of female cynomolgus monkeys with a NOAEL of 5 μg/kg bw/day (JECFA, 2000c). An ADI of 0~0.03 μg/kg bw/day was established by applying an uncertainty factor 200 to the NOAEL. The MRLs recommended by JECFA are 1, 10, 2,and 18 μg/kg for cattle muscle, liver, kidneys, and fat, respectively (JECFA, 2006c) (Table 3).
iv. Trenbolone acetate (TBA) is a synthetic anabolic steroid administered to cattle as a subcutaneous implant in the ear to increase feed efficiency either alone or in combination with estradiol-17β or zeranol (Metzler and Pfeiffer, 2001;Pottier et al., 1973) . TBA exerts its anabolic effects via binding to androgen and glucocorticoid receptors (Sillence and Rodway, 1990). The approved dose is 200 mg/implant per heifer or steer 60~90 days before slaughter (Heitzman and Hardwood, 1977). Major metabolites of TBA are the stereoisomers 17α- and 17β-trenbolone (Hoffman et al.,1984; Pottier et al., 1973). 17β-trenbolone is mainly found in muscle tissue, whereas 17α-trenbolone occurs mainly in the liver and bile excreta (JECFA, 1988). Its binding affinity to the androgen receptor is similar to that of dihydrotestosterone, but it has a stronger affinity to the progesterone receptor than progesterone (Hoffman et al., 1984). 17α-trenbolone and the other metabolites of TBA have lower binding affinities to androgen and progesterone receptors (Bauer et al., 2000). When TBA is co-administered with estradiol-17β, TBA delays estradiol excretion (Heitzman, 1983). TBA is a weak toxic chemical with an oral LD50 of 1,000~1,500 mg/kg bw. The genotoxicities of TBA, 17α-trenbolone, and 17β-trenbolone were negative in various in vitro and in vivo assays (Ingerowski et al., 1981; Lutz et al.,1988; Schiffman et al., 1988). In carcinogenicity studies, TBA given by feeding induced liver hyperplasia in mice at 0.9~9 mg/kg bw/day and islet-cell tumours of the pancreas in rats at 1.85 mg/kg bw/day, as a consequence of the hormonal activity of TBA (Schiffman et al., 1985, 1988). At a higher level of 2 μg/kg bw/day in pigs, TBA induced hormonal effects involving decreased testosterone levels in the serum of male pigs; reductions in weights of the testes, ovaries, and uteri; atrophy of testicular interstitial cells; suppression of cyclic ovarian activity; absence of glandular development of the uterine endometrium; and lack of alveolar development and secretion in the mammary glands (JECFA, 1988; van Leeuwen, 1993). Orally given ß-trenbolone induced antigonadotropic activity in castrated male rhesus macaque monkeys aged 8~17 years by the maintenance of seminal vesicle morphology and serum levels of testosterone and estradiol. The no-hormonal-effect level was evaluated as 2 μg/kg bw/day in this study (Wilson et al., 2002). JECFA (1988) recommended the ADI of TBA to be 0~0.02 μg/kg bw/day according to a no-hormonal-effectlevel of 2 μg/kg bw/day, based on hormonal effects observed in pigs and castrated monkeys, and an uncertainty factor 100. The MRLs of TBA are 2 μg/kg of β-trenbolone in cattle muscle and 10 μg/kg of α-trenbolone in cattle liver (Table 3).


a. The name ‘antibiotic growth promoters’ comes from the growth promoting effects of antibiotics, which were first discovered in the 1940s when chickens fed by-products of tetracycline fermentation grew faster than those not fed such by-products (Dibner and Richards, 2005). The modes of action of antibiotics inducing growth promoting effects are mainly through antibacterial activity and via direct metabolic effects (Butaye et al., 2003). The suppression of specific toxin-producing organisms and the sparing of feed nutrients, particularly urea and amino acids, by antibacterial agents are modes of actions inducing growth promoting effects (Dibner and Richards, 2005). By suppressing disease-causing organisms, including toxin producers, in an animal’s environment, antibiotics may reduce the incidence of clinical and subclinical diseases that hinder animal performance.The nutrient sparing effects of antibiotics come from their growth enhancement of intestinal organisms that synthesize nutrients required by the animals. Such organisms may provide vitamins and amino acids and digest cellulose to end products that are useful to the animals. In addition, they depress the growth of organisms that compete with host animals for nutrients and reduce wall thickness, implying the potential for improved absorption and explaining the nutrient sparing effects (Corpet, 2000).
b. However, many scientists, activists, regulators, and politicians have expressed urgent concerns on using antibiotics in food animals, since it could cause resistant strains of bacteria that harm human health. WHO (2002) recommended that the use of antimicrobials for disease prevention can only be justified when it can be shown that a particular disease is present on the premises or is likely to occur. Meanwhile, the control of subclinical diseases and therapeutic interventions for recognized clinical bacterial diseases by using antibacterial agents is frequently the only practical option, and therapy creates burdens in both economic and humane perspectives when disease-prevention measures fail (Phillips et al., 2004; Snary et al., 2004). Many of the concerns on the usage of antimicrobial growth promoters are focused on the contamination of food with bacteria that are resistant to antimicrobials. However, there is a continuing debate on the impact of antimicrobial use in animal husbandry and the risk of resistance transmission to human pathogens.
c. Presi et al. (2009) studied risk scoring for setting priorities in the monitoring of antimicrobial resistant bacteria in chicken, pork, beef, and veal meat distributed in four different product categories as fresh meat, frozen meat, dried raw meat products, and heat-treated meat products. They provided data that fresh and frozen chicken meat contributed 6.7% of the overall risk in the highest category, and fresh and dried raw pork meat contributed 4.0%. The contributions of beef and veal were only 0.4% and 0.1%, respectively. Hurd and Malladi (2008) revealed very low risk impacts of antimicrobial feed additives used in food-producing animals on human health by quantitative risk assessment. That is, the predicted risk of suboptimal human treatment of Campylobacter coli infections from swine is only 1 in 82 million; with a 95% chance it could be as high as 1 in 49 million for macrolides, and the risk of Campylobacter jejuni in poultry or beef is even less. In the case of penicillin, Cox et al. (2009) noted that the true risk could well be zero, providing their calculation that “not more than 0.037 to 0.18 excess mortalities per year might be prevented in the whole U.S. population if current use of penicillin drugs in food animals were discontinued and if this successfully reduced the prevalence of antibiotic-resistant E. faecium infections among intensive care unit (IUC) patients.” For streptogrammins, banning virginiamycin has been estimated to prevent from 0 to less than 0.06 statistical mortalities per year in the entire U.S. population (Cox and Popken, 2004).
d. For the purpose of risk assessment of antimicrobials used in food-producing animals, categorizations are made based on the importance of each drug class to human health: fluoroquinolones, glycopeptides, streptogramines, etc. are allocated into category I indicating very high importance;aminoglycosides, microlides, lincosamides, etc. are placed in category II indicating high importance; tetracyclines and sulphonamides are medium importance drugs in category III; and bacitracin and inophores are low importance drugs in category IV (Health Canada, 2002). When antimicrobials are proposed for usage in food-producing animals, much data are required on: the relationship between antimicrobial use in animals and the occurrence of antimicrobial resistance in human pathogens; antimicrobial resistance in animal pathogens/commensals and human health consequences; proportions of human infections caused by resistant bacteria versus susceptible bacteria; genetic aspects of antimicrobial resistance, host specificity, virulence, and the spread in animal and human populations. International bodies such as CODEX, WHO, and OIE developed several guidelines for the management of antimicrobials used in food-producing animals.
e. Antimicrobial resistance is a multi-dimensional public health issue with broad implications. Because it requires an integrated evidence-based approach of risk management, further development of appropriate risk analysis methodologies is crucial to assess the human health impact of antimicrobial use in animals
f. Regulatory approval of antibiotic applications for growth promotion in livestock has been based on demonstrable target animal safety, residual drug safety, edible tissue clearance and avoidance, and environmental safety, as well as measurable growth promoting effects. The establishment of NOAELs and ADIs of antimicrobial growth promoters are based on toxicological and microbiological evaluations. The lowest NOAEL value for the most sensitive adverse impact on human health is selected as a point of departure in risk assessment. A decision tree for the determination of adverse microbiological effects of residues of antimicrobial drugs in food-producing animals has been provided by JECFA (2000a). Emergencies of antimicrobial resistance, barrier disruption effects, and changes in specific metabolic microbiological activities are evaluated for residues of antimicrobial drugs in foods when the antimicrobials, including their metabolites, have antimicrobial properties, the drugs enter the lower bowel by any route, the ingested residues are not transformed irreversibly to inactive metabolites, the ADI derived from toxicological data is not sufficiently low to protect the intestinal microflora, and finally, the data from the therapeutic use of the drug class in humans or from in vitro or in vivo model systems indicate effects could occur in the gastrointestinal microflora.
g. Table 4 presents the risk assessment results for representative feed additives including bacitracin, tetracyclines, penicillins, streptomycin, bambermycin (or flavomycin) , tilmicosin,lincomycin, tiamulin, avilamycin, tylosin, colistin, and erythromycin along with their ADIs and MRLs.
h. As a whole, it is important to develop appropriate risk analysis methodologies for the assessment of the human health impacts of antimicrobial use in animals. One needs to bear in mind that the discontinuation of any antimicrobial used in food-producing animals without a full quantitative risk assessment may be unnecessary and even harmful to both animal and human health. Good hygiene practices should be insisted on farms, in abattoirs, during the distribution and marketing of foods, and during food preparation by consumers, and efforts concentrating on minimizing the transmission of all food-borne pathogens regardless of their antibiotic susceptibility are very important.
The use of hormonal growth promoters and antimicrobial growth promoters in food-producing animals has provoked many concerns on their human health impacts. A better understanding of human health risks posed by the use of such drugs is essential for making regulatory decisions and programs that support the prudent nonhuman use of hormonal drugs and antimicrobials. Risk assessments play a key role in the security of food safety. By following through with hazard identifications, hazard characterizations, exposure assessments, and risk characterizations, we attain more scientific background for decisions on risk management options in the protection of public health.
Recent results of risk assessments on hormonal substances including estradiol-17β, progesterone, testosterone, zeranol, trenbolone, and melengestrol acerate (MGA) indicate that natural steroid hormones have negligible human health impact when they are used under good veterinary practices, and for synthetic hormone-like substances, ADIs and MRLs are provided for the protection of human health.
resistant bacteria
Antimicrobials are used for growth promotion effects by adding them to feedstuffs at a dose lower than the therapeutic dose. The induction of resistant bacteria and the disruption of normal human intestinal flora are major concerns of human health for antimicrobial growth promoters. In many countries, impacts on normal human intestinal flora induced by residual antimicrobials or their metabolites are fully assessed, and microbiological ADIs and MRLs are established based on microbiological impacts prior to the approval of antimicrobials. However, risk assessment of antimicrobial resistance requires multi-dimensional information, including the relationship between antimicrobial use in animals and the occurrence of antimicrobial resistance in human pathogens, and the genetic aspects of antimicrobial resistance in animals and human populations, etc. Given the complexity of assessing antimicrobial resistance, the development of more appropriate risk assessment methodologies is crucially required to better understand the human health impact of antimicrobial use in animals.

8. Natural pesticides:

Those are having very less side effects since it is made out of natural material, while inorganic pesticides will reduce your immune response, it will create cancers in long run while accumulating the small portion of toxic chemical in our body on daily basis, it will act like a slow poison, it will affect children & pregnant women very easily, regular use of chemical pesticides will develop super weeds, which can be eradicated only super poisons like 2,4-Dichlorophenoxyacetic acid.


9. Say NO to Carcinogen:

a. Epidemiologic evidence on the relationship between chemical pesticides and cancer is reviewed. In animal studies, many pesticides are carcinogenic, (e.g., organochlorines, creosote, and sulfallate) while others (notably, the organochlorines DDT, chlordane, and lindane) are tumor promoters. Some contaminants in commercial pesticide formulations also may pose a carcinogenic risk. In humans, arsenic compounds and insecticides used occupationally have been classified as carcinogens by the International Agency for Research on Cancer. Human data, however, are limited by the small number of studies that evaluate individual pesticides. Epidemiologic studies, although sometimes contradictory, have linked phenoxy acid herbicides or contaminants in them with soft tissue sarcoma (STS) and malignant lymphoma; organochlorine insecticides are linked with STS, non-Hodgkin’s lymphoma (NHL), leukemia, and, less consistently, with cancers of the lung and breast; organophosphorous compounds are linked with NHL and leukemia; and triazine herbicides with ovarian cancer. Few, if any, of these associations can be considered established and causal. Hence, further epidemiologic studies are needed with detailed exposure assessment for individual pesticides, taking into consideration work practices, use of protective equipment, and other measures to reduce risk.

10. Free from Genetically Modified Organisms (GMOs) –

a. Due to the implementation of GMO, glyphosate usage has increased multi-fold which is declared as “probably carcinogenic to humans,” by World Health Organisation (WHO).
b. Genetically modified (GM) foods are foods derived from organisms whose genetic material (DNA) has been modified in a way that does not occur naturally, e.g. through the introduction of a gene from a different organism. The technology is often called “modern biotechnology” or “gene technology”, sometimes also “recombinant DNA technology” or “genetic engineering”. Currently available GM foods stem mostly from plants, but in the future foods derived from GM microorganisms or GM animals are likely to be introduced on the market. Most existing genetically modified crops have been developed to improve yield through the introduction of resistance to plant diseases or of increased tolerance of herbicides. GM foods can also allow for reductions in food prices through improved yields and reliability.
c. In the future, genetic modification could be aimed at altering the nutrient content of food, reducing its allergenic potential or improving the efficiency of food production systems. All GM foods should be assessed before being allowed on the market. FAO/WHO Codex guidelines exist for risk analysis of GM food.
d. All genetically modified foods currently available on the international market have passed safety assessments and no effects on human health have been shown as a result of consuming GM foods. When discussing and developing GM foods, three main safety issues are considered. The first is allergenicity, meaning the ability of the edited genes or food product to cause an allergic reaction. No allergic effects have been found relative to GM foods currently on the market. The second is the transfer of genes from GM foods to the human digestive tract. The probability of transfer is low; however, the use of gene transfer technology that does not involve antibiotic resistance genes is encouraged. Third is outcrossing, meaning the transfer of genes from GM organisms to other species. Several countries have developed preventative strategies, including clear separation of GM and non-GM food crops.
e. Each GM organism uses different genes and in different ways. Therefore, each GM food should be tested and their safety assessed on a case-by-case basis using international guidelines. The World Health Organization and the Food and Agriculture Organization collaborate on the Codex Alimentarius Commission, which develops the standards, codes of practice, guidelines and recommendations concerning food, including GM products.


Now we are in a position to revisit “The Green Revolution”, it needs huge corrections because it spreads its wings across the globe into the root level for more than 50 years, it is very difficult to eradicate in overnight, but even keeping small steps against it by mass volume can change the future of our children with in the next 40-50 years, for that we have to incinerate the thoughts to our kids on daily basis to switch over to our traditional healthy food slowly & we should be the role model for them for transformation, so they will copy us & they will change their lifestyle in a systematic manner over a period of time, to attain this giant target, huge mass effort is needed across the globe, at least in our nation.
If you wish your kids to be healthy in the future without heart diseases, diabetes, stress, thyroid, gastro, ortho issues etc., Just take one micro step ahead now, it will change the future generations, they will lead a healthy and prosperous life with joy & they will praise us in future.
This blog is a very tiny step towards the big target. Hope you will support the philosophy & ideology of the writer.
According to Melissa Weinberg of Deakin University, smaller goals allow us to reduce procrastination, clear our path to success and increase motivation and productivity. Without small steps, it’s harder to get started, and harder to maintain our endeavours.
