About Nutrition

• Fasting is a part of many faiths. In one study, people who ate a high-protein meal before a fast were thirstier and more uncomfortable than usual during the fast. Those whose pre-fast meals included salad and avocados—or pasta, tomato sauce, and an apple—tolerated fasting better.

• A low-calcium diet usually is advised to prevent kidney stones. But eating less animal protein and limiting salt to less than 1,000 milligrams a day may work better. In a five-year study, men on the low-protein, low-salt diet were 50% less likely to develop new stones than men on the low-calcium diet.
