Meat: Role in the Diet

Meat is a nutrient-dense source of high-biological-value protein consumed worldwide. The high protein density of meat results in a better protein to energy ratio than plant-based protein. Change in production practices over several decades has led to an overall leaner supply of meat. As a source of fat, meat contributes predominantly monounsaturated fatty acids to the diet. A 100 g serving of meat is a concentrated food source of the trace minerals iron, zinc, and selenium. Meat is also a key source of important B vitamins including thiamin, riboflavin, niacin, and, in particular, B 12 .
