Why are malnourished people often more susceptible to colds

Why are malnourished people often more susceptible to colds or other infectious diseases? Describe how a piece of steak in your mouth can become an amino acid in your blood that your cells can use to build muscle tissue, insulin, or other hormones. Describe how the body may make use of or store energy-yielding nutrients in the following two situations: A person has eaten a high-carbohydrate meal and is now running a marathon. A person has eaten a high-carbohydrate meal and is now playing video games for several days.

Solution

2). The diet that provides sufficient amounts of energy, essential amino acids, essential fats, vitamins and minerals to allow the normal growth and development processes of the body is known as “adequate diet.” Deficiency of essential nutrients in the diet or inability to absorb and utilize the nutrients from the diet results in malnutrition. Lack of nutrients such as vitamins, minerals and the other micronutrients interfere with several of the biochemical processes. Also, the protein deficiency leads to decreased muscle mass and blood volume. Certain vitamins such as vitamin C, vitamin E and B complex play a crucial role in providing an immune response. Deficiency of iron results in reduced oxygen supply, which increases the risk of infections. Reduced immune response due to nutritional deficiency is the primary cause of increased frequency of infections in malnourished people.
