Dairy-Free Diets Are Packed with Nutrients

A study published in the scientific journal Nutrition Research last November looked at the effects on nutrient intake when dairy foods are reduced or removed from the diet. Rather than focusing just on calcium—which is easily found in other foods—the researchers looked at several nutrients that are abundant in dairy products. They concluded that even when “calcium-replacement foods” provided the same amounts of calcium as dairy products, they fell short on other nutrients that milk provides.

This study was funded by the National Dairy Council and administered by the Dairy Research Institute. Two of the researchers work for the Dairy Research […]

In the book The Vegetarian Myth (which I plan to review here in the next few weeks), author Lierre Keith notes that she suffered from severe depression as a vegan partly because “there are no good plant sources of tryptophan.”
