Cooking techniques and cancer Source of ingredients Garden (home) Industrial 3rd World GMO General composition of the food Meat / vegetable Oils high fat – fecal bile acids Salt Preservatives Contaminations Toxins Storage Contaminations Fungal toxins Aflatoxins Liver cancer Dried food Keeping foods for years Traditional Industrial – treatments! Additives - dyes Methods – temperature Concentrated foods and drinks Frozen food Saves vitamins No preservatives No additives (in non-processed food) Frozen food Saves vitamins No preservatives According to the American Institute for Cancer Research, AICR, freeze-dried fruits have almost the same antioxidant phytochemicals and nutritional value as fresh fruit. Antioxidant, Mutagenic, and Antimutagenic Activity of Frozen Fruits Evaluation of polyphenols, carotenoids, and ascorbic acid showed considerable levels of these compounds in frozen fruits, even after freezing. These data suggest that frozen fruits contribute to the prevention of biological damages.

Hot foods and drinks Esophagus cancer China Japan Charcoal grilled food Healthy? Charcoal grilled food High temperature PAHs, heterocyclic amines Colorectal cancer Pancreatic cancer Breast cancer Prostate cancer Roasted food „Chinese-style roasted pork had the highest level of Heterocyclic aromatic amines (HAAs)” Quick Tip: How to Roast Peppers www.thekitchn.com (Comparing pan-fried fish, pork, and chicken, deep-fried chicken as well as fish, roasted/barbecued pork, and grilled minced beef.) Nutr Cancer. 2005;52(2):147-55 Fried food Oils – fat saturated, unsaturated reused – continuously used fume PAHs, amines Several cancers Singed/roasted food PAHs Acrylamide is a commodity chemical with many industrial and laboratory uses. It is also formed from carbohydrate and amino acid containing food by heating (primarily in fried potato products, bread, coffee). Epidemiological studies did not point to an association between either occupational or dietary exposure and an excess of cancer incidence. Food Chem Toxicol. 2008 Apr;46(4):1360-4. Microwave oven Consumption of fried or broiled foods and employment of microwave cooking, because of formation of heterocyclic amines, must be avoided because of increasing risks of oral cancer including the salivary gland tumors. Arch Iran Med. 2007 Apr;10(2):227-32. Microwave oven Usage of microwave ovens for cooking and supplementation of the diet, for example with soy-isoflavones, which have been found to suppress the occurrence of HCA-induced (heterocyclic amines) breast cancers, should be encouraged. Cancer Sci. 2004 Apr;95(4):290-9. Herbs and Spices OREGANO MAY BE PROTECTIVE AGAINST BREAST, OVARIAN, AND ENDOMETRIAL CANCERS. ROSEMARY MAY BE PROTECTIVE AGAINST BREAST, LUNG, AND SKIN CANCERS. TURMERIC MAY BE PROTECTIVE AGAISNT PROSTATE, COLON, AND SKIN CANCER. GINGER HAS ANTIOXIDANT AND ANTI-INFLAMATORY EFFECTS. . Capsaicin Several studies found that capsaicin could have an anti-ulcer protective effect on stomachs infected with H. pylori by affecting the chemicals the stomach secretes in response to infection. Chili pepper Increased risk of stomach cancer pesticides dyes fungal toxins Fermented drinks and foods Beer Wine Cereals Dairy products Birth of Probiotics ? Dr. Eli. Metchnikoff, A nobel prize winner of 1908 in physiology and medicine ”The Prolongation of life” benefits of intestinal microflora long life of the Bulgarians and their frequent use of fermented milk product ”yoghurt” Bacillus bulgaricus - Lactobacillus bulgaricus Probiotics beneficial ”life promoting” microorganisms Reduce flatulence/stomach wind Healing effect on allergy Stimulate immun defence Prevent Colon cancer Stabilise intestinal microflora Stimulate digestion of lactose Reduce risk for infection Some probiotic strains of commercial food products Lactobacillus acidophillus Lactobacillus reuteri Lactobacillus plantarum Lactobacillus casei Bifidobacterium lactis Bifidobacterium infantis Bifidobacterium longum Birth of Prebiotics ? Also early in the sixties Dr. Burkitt and also Dr. Trowell made clinical observations of great importance and pointed out the importance of some undigestible matter of vegetable origin in the human diet and the role of large intestine as an active organ of the human body Prebiotics are suitable substrates for beneficial microorganisms of the large intestine Galacto oligosaccharides Fructo oligosaccharides Iso malto oligo saccharides Xylo oligo saccharides (Soluble dietary fibre components) Beneficial effects of fermented milk -It is well known that taking fermented foods containing probiotics keeps our intestine healthy -Claimed Efficacy: chronic constipation, probiotic effect, prevention of rotavirus infection, gestroenteritis, and Traveler’s diarrhea, reduction of colon and bladder cancer, elevation of NK cell activity, anti-hypertensive effect….. Sung-Sik Yoon, Yonsei University -Fermented milk was recognized as important food as early as 4,000 BC Probiotic effects of Lactobacillus Sung-Sik Yoon, Yonsei University Risk reduction of bladder cancer by fermented milk Sung-Sik Yoon, Yonsei University Enhancement of NK cell activity by fermented milk Sung-Sik Yoon, Yonsei University 36 Thank you for your attention!
