7 Essential Components of a Healthy Diet
1. Carbohydrates ­ e.g. cakes, bread, sugar, pasta. Stored in the liver and
muscles as Glycogen. Converted to glucose and used for energy. Excess
stored as fat. 47% needed daily. Provides energy when the muscles need it.
Athletes training hard use carbohydrates, so diets should be high in this food
2. Proteins ­ e.g. meats, fish, eggs. These build muscles and repair tissues.
Builds muscles and repairs tissues, essential after injury to heal quickly.
Sports people who need large muscle size need extra protein.
3. Fats ­ e.g. milk, cheese, chocolate. Provides energy, the body needs 30%
daily. Fats release energy slowly. Increases body size and weight the body
can use the fats when there is a lack of carbohydrates.
4. Vitamins ­ fruits, carrots, liver. Helps with vision, skin/teeth/bone condition,
forming of red blood cells and blood clotting. The health of athletes helps their
performance, when training hard vitamins from the B groups are used and
need to be replenished.
5. Minerals ­ e.g. milk, red meat, green veg. Calcium helps bones grow and
makes red blood cells. Increases ability to carry O2 in the blood and therefore
keeps the body working, Prevents fatigue, aids recovery from injuries.
6. Fibre ­ e.g. cereal, leaves, seeds. There are 2 types insoluble which adds
bulk to your food, keeps food moving through the digestive system and
soluble reduces cholesterol keeping the heart healthy. Less cholesterol
keeps the heart effective and the digestive system working regularly so the
body retains less waste.
7. Water ­ e.g. fluids and food. 2/3rds of the body is made up of water. This
needs replenishing as it is lost through sweat, urine and condensation when
we breathe. It allows blood to flow more easily which is very important when
exercising as the body demands more O2. It controls the body temperature.
