Nicola, 2 things:- First of all, any controversial topic MUST be moved to the Hot Topics section, not discussed elsewhere. Not everyone wants to read this kind of anti-raw nonsense all the time, especially when there's little to back it up.
Secondly, it is highly inappropriate to take arguments from another board, in this way - what if I wasn't a member of this board? In this case, I feel obliged to post here the rebuttal I posted re Barry Grove's remarks as stated above. In future, please allow me time to post my own rebuttals on the other group and then post both sides , here.
Here are my points debunking Mr Grove's notions below:-
"
I'm afraid this is erroneous information. For one thing, the report I mentioned
http://www.newcastleyoga.com.au/links/Food%20AGEs%20text.pdfhttp://tinyurl.com/5mgyzhmade it very clear indeed that it was those foods highest in (heated) animal fats which had the highest levels of toxic AGEs(advanced glycation end products - butter being a prime example thereof, being rich in saturated fats(at 265 KU/g, in terms of AGE-content!). This, of course, doesn't even include the levels of heterocyclic amines(HCAs)(present in cooked, muscle-meats), the polycyclic aromatic hydrocarbons(PAHs) present in cooked-foods in general, among other issues.
Here's a pertinent extract from this report(the most comprehensive study of AGE-levels in foods , to date):-
"The fat group contained the highest mean AGE food
values. Among the items of this group, spreads, including
butter and processed cream cheese, margarine, and mayonnaise,
showed the highest amounts, followed by oils
and nuts (Tables 1 and 2). Thus 5-g servings of butter and
oil contained 1,300 and 450 kU AGE, respectively.
[High AGE values were also observed for the meat and
meat-substitute groups] (437 kU/g). Within this group,
highest levels were determined for cheeses, followed by
beef and poultry, tofu, fish, and whole eggs (Tables 1 and
3). [In all categories, exposure to higher temperature
achieved a greater AGE content for equal weight of the
sample]. The trend for AGE values achieved was ovenfrying
deep frying and broilingroastingboiling. Thus,
90-g servings of chicken breast prepared with these methods
yielded 9,000, 6,700, 5,250, 4,300, and 1,000 kU AGE,
respectively.
The carbohydrate group contained relatively low
amounts of AGE (3.41.8 kU/g). Within this category, the
highest AGE content was reported in processed items,
followed by grains, legumes, and starchy vegetables and
breads (Tables 1 and 4). The lowest AGE values were
detected in the milk group, followed by vegetables and
fruits (Tables 1 and 4), although infant formula contained
100-fold more AGE than natural milk.
Microwaving was shown to increase AGE content similar
to boiling cooking methods (data not shown)."
I suspect that you're actually thinking of the heat-created toxin acrylamide, which is, indeed, a carb-oriented issue.
As for the issue of (cooked) animal fats and studies on their harmful effects, there are so many studies out there, that I don't really feel the need to go on about it, but here's a small sample among numerous others on the Net):-

All I will say is that these studies are generally highly flawed as they concentrate on the negative effects of consuming cooked meats, without recognising the fact that raw animal foods do not contain the levels of toxins present in cooked animal foods which contribute to modern health-problems:-
"It has been suggested that, "given the prominence of this type of food in the human diet, the deleterious effects of high-fat foods may be in part due to the high content in glycotoxins, above and beyond those due to oxidized fatty acid derivatives." taken from
