I mainly ate red meat. The risks of red meat are well known.

Do you know what are the causes of the risk ( cancer and heart disease ) in question ?
Are there pesticide, Hormone , burnt protein or the commercial polyunsaturated fat based corn/soy oil used to grilled the red meat ?
Dietary lipid hydroperoxides induce expression of vascular endothelial growth factor (VEGF) in human colorectal tumor cells -- Jurek et al. 19 (1): 97 -- The FASEB Journal Quote:

Oxidants from endogenous sources are considered procarcinogenic agents. These include lipid peroxides formed from polyunsaturated fatty acids (PUFA) during (chronic) inflammation. Similar oxidation products may be formed exogenously from PUFA ( vegetable oil ) in dietary fats and oils. Oxidation of dietary lipids is greatly enhanced at higher temperatures during cooking. Consequently, fatty acid hydroperoxides are normal contaminants of our diet. As much as 25% of oxidized polar compounds consisting of hydroperoxides and their split products have been found in oils repeatedly used for frying. Using lipid membranes and tissue culture models, we have shown that such hydroperoxides interact with the lipid bilayer of cell membranes. They induce the formation of lipid radicals that enter the cells and cause toxic damage and disturb regulatory networks.

Myths and Truths About Beef Quote:
|
What about the accusation that beef causes cancer, in particular cancer of the colon? The genesis of this myth involves more than just muddied thinking, but actual skulduggery. In 1965 an influential physician, Ernst Wynder, took the data for the mostly processed vegetable oils, called them animal fat (which they were not) and compared them with worldwide colon cancer mortality.6 The table he produced showed high rates of colon cancer in European countries and low rates of colon cancer in Japan, and concluded that there was a positive effect, in other words, that saturated fat, the kind found in beef, caused colon cancer. What the data actually showed was that consumption of polyunsaturated vegetable oils, not saturated animal fats, was associated with the incidence of colon cancer. And Wynder forgot to mention that Asians have much higher rates than Americans of other types of cancers, particularly cancers of the liver, pancreas, stomach, esophagus and lungs.

Now you know why vegetarian French fries ( larger surface contact with trans fats and oxidized fats ) are more dangerous than deep fried Beef ?
