Nutrients and food

A nutrient is a substance used by an organism to survive, grow, and reproduce. The requirement for dietary nutrient intake applies to animals, plants, fungi .. Food is everything we eat. But all the food is not healthy. Some food does not provide nutrition

The Science of Nutrition:

The process by which a living organism assimilates food and uses it for growth, the liberation of energy and replacement of tissues is known as nutrition. Its successive stages include digestion, absorption, assimilation, and excretion. Nutritional science investigates the metabolic and physiological responses of the body to diet.

Nutrition is the science that interprets the nutrients and other substances in food in relation to maintenance, growth, reproduction, health and disease of an organism. It includes ingestion, absorption, assimilation, biosynthesis, catabolism and excretion.

The diet of an organism is what it eats, which is largely determined by the availability and palatability of foods. For humans, a healthy diet includes preparation of food and storage methods that preserve nutrients from oxidation, heat or leaching, and that reduces risk of foodborne illnesses. The seven major classes of human nutrients are carbohydrates, fats, fiber, minerals, proteins, vitamins, and water. Nutrients can be grouped as either macronutrients or micronutrients (needed in small quantities).
