Meat has been a staple of the human diet for centuries, and for good reason. It is an excellent source of essential nutrients that are difficult to obtain from other sources. In fact, some nutrients are only found in animal products.
Protein
Protein is essential for building and repairing tissues, and it is the most abundant nutrient in meat. A 3-ounce serving of cooked beef provides about 25 grams of protein, which is about half of the daily recommended intake for adults. Protein is also important for hormone production, enzyme function, and immune system health.
Iron
Iron is essential for red blood cell production, which carries oxygen throughout the body. Meat is one of the best sources of heme iron, which is the most easily absorbed form of iron. A 3-ounce serving of cooked beef provides about 3 milligrams of heme iron, which is about 20% of the daily recommended intake for adults.
Vitamin B12
Vitamin B12 is essential for nerve function and the production of red blood cells. It is found exclusively in animal products, and meat is one of the best sources. A 3-ounce serving of cooked beef provides about 2 micrograms of vitamin B12, which is about 80% of the daily recommended intake for adults.
Zinc
Zinc is essential for immune system function, wound healing, and taste perception. Meat is a good source of zinc, and a 3-ounce serving of cooked beef provides about 5 milligrams of zinc, which is about 30% of the daily recommended intake for adults.
Creatine
Creatine is a compound that is found in meat and other animal products. It is important for muscle function and energy production. Creatine has been shown to improve athletic performance, and it may also be beneficial for people with certain medical conditions, such as heart disease and Parkinson’s disease.
Meat is an important part of a healthy diet. It is a good source of essential nutrients, such as protein, iron, vitamin B12, zinc, and creatine. These nutrients are important for a variety of bodily functions, including muscle growth, red blood cell production, nerve function, and immune system health. If you are not eating meat, it is important to talk to your doctor about how to get enough of these essential nutrients from other sources.
