maintain or improve general health. It is important for lowering many chronic health risks. A balanced diet must contain carbohydrate, protein, fat, vitamins, mineral salts.It must contain these things in the correct proportions.

Balanced dietA balanced diet should contain f ats, proteins and carbohydrates in roughly these amounts:
Carbohydrates
Fat
Protein
I t should also contain water, vitamins, minerals .
Carbohydrates• These provide a source of energy. • We obtain most of our carbohydrate
in the form of starch. This is found in potato, rice, spaghetti, yams, bread and cereals. Our digestive system turns all this starch into another carbohydrate called glucose. Glucose is used by our tissues as a source of energy.
Proteins
Proteins• Proteins are required for growth
and repair.Proteins are very large molecules, so they cannot get directly into our blood; they must be turned into amino-acids by the digestive system. Our cells get their amino-acids from the blood.
Fats
FOOD
FAT• Fats are used as a source of energy:
they are also stored beneath the skin helping to insulate us against the cold. Do not think that by avoiding fat in your diet you will stay thin and elegant
• You must have some fat in your diet because it contains fat soluble vitamins.
Vitamins
Vitamins
Vitamin A: good for your eyes.Vitamin B: about 12 different chemicals.
Vitamin C: needed for your body to repair itself.
Vitamin D: can be made in your skin, needed for absorption of Calcium.
Vitamin E: the nice one - reproduction

HAEMOGLOBIN
A drop of blood contains millions of red blood cells, or erythrocytes. These specialised cells are like flattened discs, which gives them a much greater surface area with which to exchange oxygen and carbon dioxide in the lungs and with body cells. Red blood cells are able to carry oxygen so efficiently because of a special protein inside them: haemoglobin. In fact, it is the haemoglobin that is responsible for the colour of the red blood cell. Haemoglobin contains an iron atom at its centre.
Illness• Rickets is a disease of growing bone due to
deficiency of vitamin D, magnesium.
Scurvy
• Scurvy is a condition where an individual has a vitamin C (ascorbic acid) deficiency. The name scurvy comes from the Latin scorbutus, and humans have known about the disease since ancient Greek and Egyptian times.
