Although the CDC recommends 46 grams of protein for women and 56 grams of protein for men, meat-centric diets have people consuming a far higher portion of meat than that. A recent study by the University of Southern California's Davis School of Gerontology found that middle-aged individuals with diets high in animal protein have about the same likelihood of developing fatal forms of cancer as regular smokers.

Although all animal proteins, including meat, eggs, cheese, and milk, were found to have contribute to a 74 percent increased risk of death for participants in the study, plant-based proteins like beans, nuts, and lentils were not found to be a contributor in increased health risks.

The silver lining for meat lovers is that once you pass middle age and hit 65, high protein diets can actually be beneficial.
