Why is nutrition important?Nutrition refers to the various nutrients required by the human body, including vitamins, fats, proteins, minerals, water and carbohydrates. These nutrients play a vital role in the normal functioning of the body. Different nutrients have different effects on the body.

Protein is one of the essential nutrients required by the human body. It not only provides energy for the body, but is also the basic component for building muscles and cells. A reasonable intake of protein can prevent muscle loss and maintain immune function.

Carbohydrates are the main source of energy for the body. A reasonable intake of carbohydrates can provide the body with the energy it needs to maintain normal physiological functions. However, excessive carbohydrate intake may lead to problems such as obesity and high blood sugar.

Although fat is considered to be the body's reserve energy source, it is also an important component in maintaining normal physiological functions. A reasonable intake of fat can maintain the health of the skin, regulate body temperature, and promote the absorption of vitamins.

Vitamins and minerals are essential micronutrients for the human body. Vitamins help maintain the normal function of various body systems, promote bone health, and maintain immune function. Minerals are an important component of bones and play an important role in maintaining the balance of electrolytes in the body and participating in enzyme activity.
