4. Outline Introduction Autism and Dementia Obesity and Digestive Disorders Endocrine Disruption and Cancer Species in Stress (two slides) Summary

5. Autism and Dementia

6. Children today are sicker than they were a generation ago. From childhood cancers to autism, birth defects and asthma, a wide range of childhood diseases and disorders are on the rise. Our assessment of the latest science leaves little room for doubt : pesticides are one key driver of this sobering trend . * * http://www.emagazine.com/earth-talk/pesticides-and-childrens-health

7. One of the puzzling aspects of autism is the marked increase in the incidence of autism that began in the United States in the early 1980s and has appeared to increase continuously since then. - William Shaw, Journal of Restorative Medicine 2013; 2: First line of Introduction.

8. Conditions Associated with Autism Disrupted gut bacteria Deficiencies in serotonin and melatonin Impaired sulfur metabolism Is there a toxic environmental substance that has been on the rise since 1980 and that could account for these comorbidities?

10. * Cherry B. GM crops increase herbicide use in the United States. Science in Society 45, 44-46, 2010 Glyphosate use rose 1500% from 1994 to 2005. * 100 million pounds of glyphosate is used every year on more than a billion acres. Huge expansion of GMO Roundup-Ready corn, soy, cotton and canola crops has led to sharp increases in the last decade

13. Is Glyphosate Nontoxic? Monsanto has argued that glyphosate is harmless to humans because our cells dont have the shikimate pathway, which it inhibits However, our gut bacteria DO have this pathway We depend upon them to supply us with essential amino acids (among many other things) Other ingredients in Roundup greatly increase glyphosates toxic effects Insidious effects of glyphosate accumulate over time Most studies are too short to detect damage

14. Main Toxic Effects of Glyphosate * Kills beneficial gut bacteria and allows pathogens to overgrow Interferes with function of cytochrome P450 (CYP) enzymes Chelates important minerals (iron, zinc, manganese, etc.) Interferes with synthesis of aromatic amino acids and methionine Leads to shortages in critical neurotransmitters Disrupts sulfate synthesis and sulfate transport * Samsel and Seneff, Entropy 2013 , 15 , 1416-1463

15. Some Biomarkers for Autism Disrupted gut bacteria; inflammatory bowel Low serum sulfate Methionine deficiency Serotonin and melatonin deficiency Defective aromatase Zinc, iron and vitamin D deficiency Urinary p-cresol High serum nitrate and ammonia Impaired immune function Chronic low-grade inflammation in the brain

16. Some Biomarkers for Autism Disrupted gut bacteria; inflammatory bowel Low serum sulfate Methionine deficiency Serotonin and melatonin deficiency Defective aromatase Zinc and iron deficiency Urinary p-cresol High serum nitrate and ammonia Impaired immune function Chronic low-grade inflammation in the brain These can all be explained as potential effects of glyphosate on biological systems

18. Obesity and Digestive Disorders

19. Is Glyphosate Making Us Obese?

20. * Figure 1 in R.J. Johnson et al., Am J Clin Nutr 2007;86:899906. Obesity in US over Time * Glyphosate was introduced into the food chain in 1975

21. Nancy Swanson, http://www.examiner.com/article/ data-show-correlations-between-increase-neurological-diseases-and-gmos

22. Gut Microbes and Obesity Our microbes outnumber our own cells 10 to 1 There are between 200 and 300 different species in a typical person. Environmental toxins like glyphosate can cause an overgrowth of pathogens in the gut They release toxic phenols This can lead to inflammatory bowel disease And a direct path to obesity! Gut microbes from an obese person induced obesity in mice* *N. Fei and L. Zhao, The ISME Journal, Online Publication Dec. 2012

23. Pigs Fed GMOs Develop Inflamed Gut * * J.A. Carman et al., Journal of Organic Systems, 8(1), 2013. Pigs have a similar digestive system to humans Digestive problems observed anecdotally in GMO-fed pigs inflammation in stomach and intestine, stomach ulcers, thinning of intestinal walls, increase in haemorrhagic bowel disease Follow-on Experiment: 168 just-weaned pigs fed "typical diet, soy and corn, until slaughtered Half fed GMO versions, half organic.

24. Pigs Fed GMOs Develop Inflamed Gut * * J.A. Carman et al., Journal of Organic Systems , 8(1), 2013. Blind autopsies conducted Female pigs' uterus 25% larger in GMO-fed pigs Female pigs 2.2x more likely to get severe stomach inflammation on GMO diet Males were 4x more likely Photos kindly provided by Howard Vlieger GMO Feed GMO Feed Non-GMO Feed

25. Human Digestive System Disorders We are seeing an alarming increase in the US in many diseases related to the gut Crohns disease, inflammatory bowel disease, colitis, acid reflux disease, gluten and casein intolerance, celiac disease, leaky gut The gut-brain axis links neurological disorders with gut disorders I believe that glyphosate is a major cause

30. We may be able to knock out 80% to 90% of the resistant ryegrass with glyphosate. Advantages: Hastens maturity to harvest Weed control for next year's crop Reduces green material and therefore strain on harvesting machinery Disadvantages Herbicide cannot be washed out prior to human use. Animals fed herbicide-treated crops --> contamination in animal products Crops include wheat, barley, legumes, corn, sunflower, kiwi, grapes (wine), raspberries, apples, soybeans, alfalfa, sugar cane Desiccation with Glyphosate * * Ron Smith, Western Farm Press, Mar. 23, 2013

31. Celiac Disease, Glyphosate and Non Hodgkins Lymphoma Glyphosate preferentially kills bifidobacteria * Bifidobacteria are depleted in celiac disease ** Celiac disease is associated with increased risk to non Hodgkins lymphoma *** Glyphosate itself is also linked directly to non Hodgkins lymphoma **** * A.A. Shehata et al., Curr Microbiol. 2013 Apr;66(4):350-8. ** M. Velasquez-Manoff, NY Times Sunday Review, Feb. 23, 2013. *** C. Catassi et all, JAMA. 2002 Mar 20;287(11):1413-9. **** M.

34. Acute Kidney Disease Death Rate Plotted Against Glyphosate and GMOs * * Plot prepared by Nancy Swanson from available data online Sri Lanka and El Salvador have now banned glyphosate usage in agriculture

35. Endocrine Disruption and Cancer

36. Roundup Safety Claims Disputed * It is commonly believed that Roundup is among the safest pesticides. Despite its reputation, Roundup was by far the most toxic among the herbicides and insecticides tested. This inconsistency between scientific fact and industrial claim may be attributed to huge economic interests, which have been found to falsify health risk assessments and delay health policy decisions. * R. Mesnage et al., Biomed Research International, 2014 In Press

37. Glyphosate is an endocrine disruptor that promotes breast cancer * Low and environmentally relevant concentrations of glyphosate possess estrogenic activity Glyphosate caused human hormone-dependent breast cancer cells to proliferate at concentrations of parts per trillion * S. Thongprakaisang et al., Food Chem Toxicol. 2013 Jun 8. S0278-6915(13)00363-3.

38. Mammary Tumors in Rats * * G.-E. Sralini et al., Food Chem. Toxicol. (2012) [retracted] http://dx.doi.org/10.1016/j.fct.2012.08.005 Rats through their entire lifespan exposed to Roundup at levels well below established safety limits

39. Glyphosate and Anencephaly * Yakima, Benton and Franklin counties in Washington State have an unusually high number of pregnancies affected by the birth defect, anencephaly 75 pesticides were analyzed in studying contamination due to surrounding agriculture 47 (63%) of these were detected Glyphosate was applied in large amounts, but was not studied 5% solution of glyphosate was also used heavily around irrigation ditches to control weeds Main herbicide recommended due to its low toxicity Glyphosate has been linked to anencephaly due to its effect on retinoic acid * Barbara H. Peterson . Farm Wars , http://farmwars.info/?p=11137

40. Glyphosate Upregulates Retinoic Acid * Small Brain * A. Carrasco, Teratogenesis by glyphosate based herbicides and other pesticides. Relationship with the retinoic acid pathway. In Breckling, B. & Verhoeven, R. (2013) GM-Crop Cultivation Ecological Effects on a Landscape Scale. Theorie in der kologie 17. Frankfurt, Peter Lang.

41. An Important Paper (2012) A substantial body of evidence demonstrates that glyphosate and Roundup cause teratogenic effects and other toxic effects on reproduction, as well as genotoxic effects. From an objective scientific standpoint, attempts by industry and government regulatory bodies to dismiss this research are unconvincing and work against the principle that it is the responsibility of industry to prove that its products are safe and not the responsibility of the public to prove that they are unsafe.

42. Glyphosate Kills Liver Cells * Doses far below those used in agriculture kill liver cells in vitro Downregulated synthesis of glutathione, critical for detox of environmental chemicals Upregulated synthesis of CYP enzymes Likely due to interference with their function * C. Gasnier et al., Journal of Occupational Medicine and Toxicology 2010, 5:29.

43. Species in Stress

44. Species in Stress * R. Mason et al., Journal of Environmental Immunology and Toxicology 1:1, 3-12; 2013 Fungus Infection Fungus Infection Fungus Infection Fungus Infection

45. Roundup herbicide enhances the growth of aflatoxin-producing fungi * * Barberis et al., Journal of Environmental Science and Health, Part B: Pesticides, Food Contaminants, and Agricultural Wastes. 2013, 48(12), 1070-1079.

46. Aflatoxins are mutagenic, carcinogenic, teratogenic, hepatotoxic, immunosuppressive, and they also inhibit several metabolic systems * * Barberis et al., Journal of Environmental Science and Health, Part B: Pesticides, Food Contaminants, and Agricultural Wastes. 2013, 48(12), 1070-1079.

47. Summary I believe we need to be very worried about glyphosate in the food and water supplies Glyphosates disruption of gut bacteria, depletion of essential amino acids and minerals, and interference with cytochrome P450 enzymes have widespread consequences Glyphosate may be the most important factor in the recent die-off of many species Glyphosate may be the most important factor in the U.S. health crisis related to obesity, autism, dementia, celiac disease, kidney failure, etc.
