Answer:

Explanation:

A balanced diet is a diet that contains differing kinds of foods in certain quantities and proportions so that the requirement for calories, proteins, minerals, vitamins and alternative nutrients is adequate and a small provision is reserved for additional nutrients to endure the short length of leanness

Carbohydrates

Carbohydrates play important roles within our body. They are the primary energy source that our brain and muscles use. Approximately 55-60% of our calories should come from carbohydrates. Carbohydrates are energy foods and provide 4 calories per gram. We need carbs not only to support our growth but to also fuel our activity.

Protein

Protein is used by our body helps us develop and grow properly. Protein makes up our muscles, organs, skin and hair. Protein is broken down into amino acids. The body is able to make 12 amino acids but we need the remaining 8 (essential amino acids) to ensure good health. Protein is used for building, maintaining and repairing body cells and organs. They also make hormones and enzymes which regulate body functions. Antibodies are also made and other important components of the immune system.

Fats

Approximately no more than 35% of our daily calories should come from fat. Fats are a great source of energy: 1g of fat provides 9 calories. Fat protects the internal organs, however, too much fat can be damaging.

Vitamins

Vitamins are complex organic substances found in our food which support almost every system in the body, including the immune system, the brain and the nervous system. Many of them help convert food into energy and help the body to use carbohydrate, fat and protein.

Minerals

Minerals are elemental substances and are found in the soil. They are absorbed by plants, which we eat or are eaten by animals – which we then eat. Therefore we can get minerals from both animal and vegetable sources. Minerals have many different roles, including structural roles, such as calcium in bones and teeth or regulator roles such as sodium and potassium in fluid balance and muscle contractions. Minerals do not deteriorate in the same way that vitamins do because they are ‘elemental’ they cannot be easily destroyed by heat, light or air.

Water

Water is one of the most important macronutrients along with carbohydrates, proteins and fats. We can live a little longer without food (around 8 weeks) than we can water (only a few days). A 12% drop in body weight through water is always fatal. Our body is made up of around 65% water, it assists with absorption, digestion, excretion and aids circulation of nutrients around our body. Water is also essential for regulating our bodies temperature and distributing heat. Water also lubricates our bodies moving joints and our eyes.
