Malnutrition is defined as an imbalance between nutrient supply and the demands of growth, maintenance and specific activities of the body.
Risk factors. There are two groups especially vulnerable to malnutrition: children and the elderly.
Symptoms. Symptoms vary according to what causes malnutrition, but in children it is usually manifested as fatigue, dizziness, weight loss and growth retardation.
Treatment. When a person cannot eat enough nutrients to meet his needs, the body begins to waste away: first fat and then muscle loss. There is no food that contains all the nutrients needed. Therefore, we must ensure food is varied and eaten in a moderate and balanced manner.
