Micronutrients, often referred to as vitamins and minerals, are vital to healthy development, disease prevention, and wellbeing.

Malnutrition is a condition that results from eating a diet which does not supply a healthy amount of one or more nutrients. This includes diets that have too little nutrients or so many that the diet causes health problems. Undernourishment is most often due to a lack of high-quality food which is available to eat. Infectious diseases such as gastroenteritis , pneumonia , malaria , and measles , which increase nutrient requirements, can also cause malnutrition. Other causes of malnutrition include anorexia nervosa and bariatric surgery. Efforts to improve nutrition are some of the most effective forms of development aid.

For example, wheat is rich in carbohydrates, but poor in nutrients like proteins and fats. Too much intake of wheat products results in a deficiency of proteins and fats, which reduces growth. Lack of proteins also results in stunted growth, skin diseases, swelling of the face and discolouration of the hair, and even causes diarrhoea.

Nutrient intake recommendations and national nutritional policies have focused primarily on prevention of short-latency deficiency diseases. Most nutrient intake recommendations today are based on prevention of the index disease only.
