TylerDurden:
This is an ongoing, unfinished thread detailing the toxins in cooked-foods and loss of nutrients caused by cooking and freezing(please don't post here):-

Cooking causes an increase in aging/sensescence by creating advanced glycation end products(AGEs):-

Here's a reference which show that cooking reduces protein digestibility of meats:-

"From Oste [1991], heating (above 100°C, or 212°F) decreases meat protein digestibility. Frying chickpeas, oven-heating winged beans, or roasting cereals at 200-280°C (392-536°F) reduces protein digestibility.

Seidler [1987] studied the effects of heating on the digestibility of the protein in hake, a type of fish. Fish meat heated for 10 minutes at 130°C (266°F), showed a 1.5% decrease in protein digestibility. Similar heating of hake meat in the presence of potato starch, soy oil, and salt caused a 6% decrease in amino acid content."

Heterocyclic Amines in Cooked-Meats:-

Microwaving at high temperatures have been shown to heavily reduce the anti-infective factors in human milk:- http://www.ncbi.nlm.nih.gov/pubmed/1557249

http://findarticles.com/p/articles/mi_m1200/is_n17_v141/ai_12100730

Microwaving has also been shown to be the worst type of cooking for cooking vegetables, as it virtually eliminates the antioxidants present in vegetables:-

http://www.ncbi.nlm.nih.gov/pubmed/17979232

Microwaving has also been shown to reduce vitamin B12 levels in foods to a much greater extent than any other form of cooking:-

Nitrosamines, which are present in processed and smoked meats, have been noted as being carcinogenic, being linked to stomach-cancer:-

A more minor online dictionary entry re the subject is found here:-

There are also concerns regards advanced glycation end products
http://en.wikipedia.org/wiki/Advanced_glycation_endproduct
, otherwise known as AGEs, toxins which are present in cooked-foods in sizeable amounts and which
contribute to age- and diabetes-related diseases

http://hyper.ahajournals.org/cgi/content/abstract/46/1/232

Here's the most famous report so far on the typical AGE-content of several common foods:-

Acrylamide,
http://en.wikipedia.org/wiki/Acrylamide
, a toxin found in baked/fried/grilled starchy foods, but not in boiled or raw foods, has been linked to endometrial, ovarian but not breast cancers in humans, and is a proven carcinogen in animals:-
http://www.ncbi.nlm.nih.gov/pubmed/18006919

Also, toxic compounds called PAHs/polycyclic aromatic hydrocarbons, info shown on http://www.atsdr.cdc.gov/tfacts69.html#bookmark02 and http://en.wikipedia.org/wiki/Polycyclic_aromatic_hydrocarbon (s) and

http://www.ncbi.nlm.nih.gov/pubmed/18675309

present in processed, smoked and cooked foods as well as in coal and tar deposits, are known to be carcinogenic:-

http://www.ncbi.nlm.nih.gov/pubmed/18314326

German research in 2003 showed significant benefits in reducing breast cancer risk when large amounts of raw vegetable matter are included in the diet. The authors attribute some of this effect to heat-labile

phytonutrients http://www.ncbi.nlm.nih.gov/pubmed/14690788

There have been various studies made concerning the negative effects of pasteurised milk:-

Poncho:
Is there a post with more recent stuff?
I really suck at navigating the forum haha

TylerDurden:
I'm not sure what you mean. The above is pretty all-inclusive re data on the harm done by cooking.http://en.wikipedia.org/wiki/Raw_foodism#Toxins_created_by_cooking

That and the next 2 sections are of interest, and might summarise things better.

Poncho:
haha
I just know that there are progressions being made constantly.
I was thinking there should hopefully be new information too
