Cooking food destroys enzymes that help in the digestion process, reduces nutrients and phytochemicals, and reduces some of the protective effects of food.
Steaming vegetables briefly (and keep the leftover water for stock because it is full of the nutrients lost in the steaming) results in a loss of under 30% of enzymes, so still helps in your digestion.
Boiling (in soups, stews) also keeps a lot of the nutrients in the broth and is healthier for you than bbq, baking, grilling or frying.
Cooking muscle meat, including beef, pork, fish or poultry, at high temperatures (such as frying or grilling on an open flame/bbq) causes heterocyclic amines (HCAs) to form. Exposure to high levels of HCAs could cause cancer. (more at cancer.gov)
Browning of food (when an amino acid reacts with a reducing sugar, usually requiring heat) such as roast beef or seared steak causes advanced glycation end-products (AGEs), which have been linked to diabetes (one of many studies here).
Good news, though – cooked tomatoes, for example ketchup, has been proven to help prevent prostate cancer.
Not all raw food is good for you, though. Raw button mushrooms contain agaritine which is toxic to your liver and raw shitake mushrooms contain formaldehyde. Cook six minutes and it reduces these harmful toxins greatly, or marinate and dehydrate. Buckwheat greens contain fagopyrin which is toxic to humans and can cause hypersensitivity to sunlight, skin irritation, swelling, and dizziness.
Many sea vegetables, like kelp and hijiki have been found to have high heavy metal content, as a result of the pollution found in our oceans. Arsenic and mercury have been found in high quantities in hijiki and should be avoided.
If you decide to become a raw foodist (or even a vegan) you need to take supplements of B12 and Vitamin D (if no exposure to the sun – for example in winter) and make sure to eat Omega-3 fatty acids (walnuts, flax seed oil).
Raw foods have been found to benefit arthritis, fibromyalgia, obesity, type 1 and 2 diabetes, heart disease and cancer. Raw foods have anti-inflammatory properties that will help with anyone who has problems in their joints. The high amount of fiber binds and carries out carcinogens from your body.
“Who am I?”
“I am a 31 year-old woman living in Toronto, Canada. I work as a server to pay the bills in an Irish Pub where I wear a kilt and serve a lot of beer and nachos. I write as my passion and sometimes for a little money or free tickets. I’m hoping one day my writing could help pay a bill or two. I have a Bachelor of Arts in Theatre and Graduate Diploma in Journalism. Hence, a lot of my published articles are more about theatre than anything else. Here are links to a couple of my favourite pieces that are published on the web:
