A new study confirms past research which indicates that a diet high in protein, particularly in middle age, will increase mortality. This study dovetails with the conclusions of the EPIC study  in Europe which found that you should limit your meat consumption to 40 grams (roughly 1.5 ounces) per day.
Excerpt: “In a study Hu authored, people who ate a serving of red meat every day had a 13 percent eta-i.org/cialis.html increased risk of mortality, compared with those who ate little meat. By comparison, people who swapped out red meat for alternative sources of protein cut their risk of premature death. Choosing chicken and other poultry decreased the risk by 14 percent, fish decreased the risk by 7 percent and legumes decreased the risk by 10 percent”.
