DailyDirt: Eat Less Red Meat. Cows Rejoice!

- Two recent studies in mice and in humans suggest that a high-protein, high-fat diet may shorten our lifespan. Instead, we should probably be eating a high-carbohydrate, low-protein diet (and settle with having more body fat as a result) -- which is the complete opposite of popular diet fads, like the Atkins Diet.

- Phew! Saturated fat and cholesterol may play only a small role in the increased incidence of heart disease in red-meat eaters. However, the bad news is that it turns out that our gut bacteria metabolize the chemical carnitine (which is present in large amounts in red meat and is also added to energy drinks), leading to the production of another chemical called TMAO that enters our blood stream and increases our risk of heart disease. Apparently, TMAO helps cholesterol enter artery walls and prevents the body from getting rid of excess cholesterol. [url]
- A Harvard study found that eating just a single serving of red meat each day could increase a person's risk of death by 13%. While that may not change the minds of die-hard red meat fans who would rather die than give up red meat, it might be worth considering eating alternative (healthier?) protein sources. [url]
