- Cell repair and maintenance. Proteins are used to build and repair cells throughout the body, including muscle, skin, bone, and blood cells. As we age, our bodies become less efficient at repairing cells, so adequate protein intake is essential for maintaining good health.
- Muscle mass maintenance. Muscles are made up of proteins, and without enough protein, they can begin to break down. This can lead to weakness, fatigue, and difficulty performing everyday activities. Exercise and consuming enough protein can help to maintain muscle mass and strength.
- Hormone production. Proteins are used to produce hormones, which are chemical messengers that regulate many different bodily functions, including growth, metabolism, and reproduction.
- Immunity. Proteins play a role in immune function, helping to protect the body from infection and disease.
- Appetite regulation. Proteins can help to regulate appetite, keeping us feeling full and satisfied after eating. This can help to maintain a healthy weight and reduce the risk of obesity.
The recommended daily intake of protein for adults is 0.8 grams per kilogram of body weight per day. However, some people may need more or less protein depending on their age, activity level, and health status.
