✒️ - By Aan Gray
Before discussing the digestive system, it is necessary to understand the body's nutritional needs, i.e. the dietary constituents and their functions. Food provides nutrients, some of which are broken down to provide energy while others are needed to maintain health, e.g. for growth and cellular metabolism. These substances are:
• Carbohydrates
• Proteins
• Fats
• Vitamins
• Mineral salts, trace elements, and
• Water.
Many foods contain a combination of nutrients, e.g. potatoes and bread are mainly carbohydrate, but both also contain protein and some vitamins. Fibre, more correctly known as non-starch polysaccharide (NSP), consists of indigestible material. Although it is not a nutrient as it is neither a source of energy nor essential for cellular metabolism, NSP is important in the diet as it has many beneficial effects on the body.
The diet is the selection of foods eaten by an individual. A balanced diet is essential for health and provides appropriate amounts of all nutrients in the correct proportions to meet body requirements. An essential nutrient is a substance that cannot be made by the body and must therefore be eaten in the diet.
Many health problems arise as the result of poor diet. In developed countries, obesity is increasingly common, while in other countries, malnutrition is widespread; and so, to live a good life, you need good food.
