Blood lead levels are lower in Chinese adults eating more tofu - Scientific update: a review of recent scientific papers related to vegetarianism - Brief Article

Vegetarian Journal,  Nov-Dec, 2001  by Reed Mangels

Lead is a mineral that is toxic to humans. Nutritional factors such as protein, calcium, iron, zinc, and vitamin C can change how much lead is absorbed and excreted. More than 1,100 young Chinese adults had the amount of lead in their blood measured. Those eating the most tofu (more than 25 ounces per weed had blood lead levels that were 11% lower than the levels of lead seen in those eating less than eight ounces of tofu per week. The high calcium content of tofu may interfere with lead absorption and reduce the amount that is retained. It is very important to limit exposure to lead. Dietary adjustments like eating more tofu may provide additional protection.
