Biology lesson: (Im studying Biology right now since there’s exam)
The food pyramid
Food pyramid can be used as a guideline to plan a balanced diet. In the food pyramid, foods are classified into six food groups. The amounts of the six food groups in a balanced diet are represented by their relative sizes in the food pyramid. In addition to the amounts and proportions, we should also choose a variety of food from each group to ensure enough of various kinds of minerals and vitamins are obtained.
- Fats, oils, salt and sugar (Eat the least)
They are needed in very small amounts. Eating too much fatty and sugary foods will lead to overweight and heart disease. Too much salt may lead to high blood pressure.
- Milk and alternatives (1 - 2 glasses / day) 3. Meat, fish, eggs and alternatives (5-8 tael / day)
They are rich in proteins, vitamins and minerals. They are needed for growth and repair of the body, and maintaining health.
- Vegetables (> 3 servings / day) 5. Fruits (> 2 servings / day)
They are rich in vitamins, minerals and dietary fibre. They are needed for maintaining health.
- (Grains & 3-8 bowls / day)
They provide us with energy readily. Some of them (e.g. wholemeal bread) are rich in dietary fibre.
