red meat

Red meat is defined as the meat from mammals, such as beef, pork, lamb, and veal. Lean red meat, consumed in moderation, can be a healthy part of a balanced diet, providing essential amino acids, iron, zinc, and B vitamins. It is a convenient source of protein, as most plant foods do not offer all essential amino acids in a single serving.12

However, studies suggest a link between the consumption of meat, particularly red and processed meat, and a modest increase in the risk of colorectal cancer. While the exact cause is unclear, it may be related to specific components of meat or the absence of other nutrients like fiber in high-meat diets. Meat contains virtually no carbohydrates, as glycogen is broken down during its conversion from muscle.34
