That heating food above 104–118 °F (40–48 °C) degrades enzymes in raw food that aid digestion, when in fact enzymes in food play no significant role in the digestive process, prior to being digested themselves.
That raw foods have higher nutrient values than foods that have been cooked, when in fact cooking affects nutrient contents variably – depending on the plant food and cooking method – and may actually increase availability of fat-based nutrients, such as vitamin E and beta-carotene.
That foods cooked at high temperatures, especially meat, may contain harmful toxins, including trans fatty acids produced by heating oil, acrylamide produced by frying, advanced glycation end products (AGEs), and polycyclic aromatic hydrocarbons. Not all cooked food contains harmful chemicals, and a diet containing a mix of cooked and raw food is normal. According to the American Cancer Society, it is not clear as of 2019 whether acrylamide consumption affects the risk of cancer. Public health authorities recommend reducing consumption of overly cooked starchy foods or meats.
Health effects
A raw food diet is likely to impair the development of children and infants. Care is required in planning a raw vegan diet, especially for children, as there may not be enough vitamin B12, vitamin D, and calories for a growing child on a totally raw vegan diet.
Food poisoning is a health risk for all people eating raw foods, and increased demand for raw foods is associated with greater incidence of foodborne illness,especially for raw meat, fish, and shellfish. Outbreaks of gastroenteritis among consumers of raw and undercooked animal products (including smoked, pickled or dried animal products) are well-documented, and include raw meat, raw organ meat, raw fish (whether ocean-going or freshwater), shellfish, raw milk and products made from raw milk, and raw eggs.
One review stated that “Many raw foods are toxic and only become safe after they have been cooked. Some raw foods contain substances that destroy vitamins, interfere with digestive enzymes or damage the walls of the intestine. Raw meat can be contaminated with bacteria which would be destroyed by cooking; raw fish can contain substances that interfere with vitamin B1 (anti-thiaminases)”
I don’t speak for all of lemmy, but yeah I think I am going to hate on the raw food movement
