Previous studies in the U.S. have found that a low-carbohydrate diet is associated with an increase in overall mortality and showed that when such a diet is from animal-based products, the risk of overall, as well as CVD and cancer mortality, is increased even further (Fung et al., 2010; Lagiou et al., 2007). They inject patients with radioactive methionine to measure the size and location of brain tumors, and because brain tumor cells gobble it up, tumors will light up on a scan much brighter than surrounding cells. Found insideMeat holds an important position in human nutrition. Although protein from this source has lower biological value than egg albumin, it is an exclusive source of heme iron and vitamins and minerals.
