Save the Meat for the Weekend
The recent Western obsession with protein diets is turning out to have potentially fatal results, namely osteoporosis and kidney failure. During protein metabolism, your kidneys must excrete the excess components of protein, known as amino acids.
To complete this process, the kidneys neutralize the acids by binding them to calcium, which in turn, depletes your body's store of this essential mineral.
The rate in the U.S. of osteoporosis is strikingly higher than China, where almost everyone eats a lower protein vegetarian diet. Evidence has also been found that excess protein weakens the kidney function. But you don't have to give up meat entirely to attain longevity.
In studies of animals with chronic kidney failure, simply reducing their intake of protein extended their lifespan by up to 50 percent! Take this advice: limit your meat eating to only the weekends, and you will be taking a balanced and healthy approach to your diet.
