Even though a student may not have much money, eating to stay mentally and physically active and able to concentrate need not be a problem.
This student eating guide aims to give you the confidence to eat nutritiously (有营养地) , cheaply and enjoy ably whatever your cooking skills are.
So what is a healthy diet？ Healthy eating is not just avoiding less healthy foods—it is eating foods that are positively good for our health. Here are five steps to healthy eating.
1. Have regular meals. Feed your brain nutritiously on a regular basis and it is more likely to work efficiently.
2. Aim to eat a third of your food as starchy(含淀粉的)food, e. g. bread, rice, potatoes—all relatively cheap and nutritious.
3. Eat plenty of fruit and vegetable. They are good to people's health.
4. Cut down on fat. Choose such meat as chicken, try low fat milk and avoid fried food.
5. Eat less sugar. Try to reduce the number of times you eat sweets, chocolate, etc.
It is the diet as a whole that is important. Variety helps to ensure a nutritional (营养的) balance. There are no"bad foods"but there are"bad diets".
