A healthy diet improves the physical and mental health of an organism. This requires ingestion and absorption of vitamins, minerals, essential amino acids from protein and essential fatty acids from fat-containing food. Carbohydrates, protein and fat play major roles in ensuring the quality of life, health and longevity of the organism. [10]
Macronutrients are defined as a class of chemical compounds which humans consume in relatively large quantities compared to vitamins and minerals which provide humans with energy. Fat has a food energy content of 38 kilojoules per gram (9 kilocalories per gram) proteins and carbohydrates 17 kJ/g (4 kcal/g).
All of our energy comes from the calories we eat, and all calories come from three categories: protein, fat and carbohydrates. These are called “macronutrients.”
In general, micronutrient deficiencies can lead to serious health problems, blindness, muscle weakness, join pain, dry skin, brittle hair and nails, constipation, poor growth and premature death ...
The World Health Organization has estimated that 2.7 million deaths each year are attributable to a diet low in fruit and vegetables during the 21st century. [65] At least 1.2 billion women are low of vitamins and minerals, which increases the risk of being exposed to chronic fatigue, low resistance to infections and birth defects in their ...
Nutritional science (also nutrition science, sometimes short nutrition, dated trophology [1]) is the science that studies the physiological process of nutrition (primarily human nutrition), interpreting the nutrients and other substances in food in relation to maintenance, growth, reproduction, health and disease of an organism.

The Dietary Reference Intake (DRI) is a system of nutrition recommendations from the National Academy of Medicine (NAM) [a] of the National Academies (United States). [1] It was introduced in 1997 in order to broaden the existing guidelines known as Recommended Dietary Allowances (RDAs, see below).
