Meat and human health

Many studies have examined the influence of meat consumption on human health. Meat eaters have a higher body mass index and more weight gain than vegetarians. The risk of type 2 diabetes has also been linked to high meat consumption. However, the statistical correlations with these metabolic disorders are weak. There is inconsistent evidence of a higher cardiovascular risk. In all cases it is difficult to not consider the overall type of food consumed. A link between high meat consumption and cancer, particularly colorectal cancer, has been observed in nearly all epidemiological studies. Some studies have also shown a link with breast, prostate and lung cancer. The mode of cooking could be partly responsible for this effect, due for example to heterocyclic aromatic amines production during grilling and intensive cooking. Quantitative and qualitative advice can be given from these observations.
