In this Facts About Beef article, it compares vegetarian diets with diets with lean meat.

• According to a recent Gallup poll, only 5% of American adults consider themselves to be vegetarians.

• Experts agree that the healthiest diets include a balance of fruits and vegetables, whole grains, low-fat dairy and moderate portions of nutrient-dense lean meat and skinless poultry.

• Vegetarian diets lacking in nutrients can lead to deficiencies. Unlike plant proteins, beef is a source of high-quality protein and is the food supply's most readily available and easily absorbed source of iron and zinc. According to the CDC (Centers for Disease Control and Prevention), iron deficiency is the most common nutritional deficiency worldwide and can be caused by improperly planned vegetarian diets.

• Beef is an excellent source of vitamin B12, an essential nutrient that is not readily available in plant protein sources.
