Protein makes you lean. You need to eat more protein for muscles to grow. Vegans can’t get sufficient protein. Red meat is bad. Men should not eat soy. Humans should not consume dairy. These are some of the protein myths that just won’t go away. Allow me to set the record straight.
Myth No. 1: Protein’s main role is in muscle development.
As an essential nutrient composed of building blocks known as amino acids, protein is not only a component of muscle, but also of bone, joint, tendons, ligaments, hair, antibodies, hormones, enzymes and LDL and HDL cholesterol. The nutrient supports a healthy immune system, can regulate blood glucose and plays a role in body composition.
Myth No. 2: Cutting way back on protein is a good way to lose weight.
Consuming insufficient protein can actually make it harder to lose weight since the nutrient helps keep you full and your metabolism boosted. If you do lose weight by cutting the protein, chances are it’s muscle – not fat – loss. What’s more, not eating enough protein can lead to other side effects including fatigue, weakness, leg swelling (edema) and a suppressed immune system, which can result in more frequent illness. Losing weight is hard enough without those problems, too.
