What is a healthy diet?

1, when choosing fast food, in order to control calorie intake, try not to order high-calorie fast food; Pay attention to the choice of food when ordering. Take the Big Mac package as an example. A Big Mac has 570 calories, French fries 220 calories and Coke 150 calories. After eating a meal, the calories are nearly 940 calories. If you add an apple pie (220 calories) or a chocolate milkshake (380 calories), you will exceed the calorie limit. So it's best to order a single meal, choose a Big Mac at the same time, drink low-calorie drinks or match lettuce salad to supplement insufficient nutrition. 2. For convenience foods, including quick-frozen convenience foods such as jiaozi, fruits and vegetables, fish, bean products, etc., attention should be paid to supplementing cellulose and vitamins. In order to keep the color, texture and taste of food, convenience food retains a lot of nutrients, but it will cause some loss of cellulose and water-soluble vitamins during processing. Pay attention to using fresh vegetables and fruits to accompany meals when eating. 3. The quality of three meals has its own emphasis. Breakfast is nutritious, lunch is comprehensive and dinner is light. Nutritional breakfast: The foods that can be selected in the breakfast menu are: cereal bread, milk, yogurt, soybean milk, boiled eggs, lean ham or beef, chicken, freshly squeezed vegetables or fruit juice, so as to ensure the intake of protein and vitamins. A hearty lunch: lunch requires a full range of foods, which can provide various nutrients, relieve work pressure and adjust mental state. You can spend more time matching yourself with a reasonable diet: Chinese fast food, mixed fried rice, fried noodles with shredded chicken, steak, pork chop, hamburger, green salad or fruit salad, plus a soup. Dinner is light: dinner should be light, pay attention to choose foods with less fat and easy digestion, and be careful not to overeat. Overnutrition at dinner, which can't be consumed, will accumulate in the body, causing obesity and affecting health. The best choice for dinner: noodles, rice porridge, fresh corn, beans, vegetarian stuffed buns, side dishes and fruit platters. It is also good to drink a small glass of rice wine or red wine with meals occasionally. 4, pay attention to food collocation, including coarse and fine, dry and thin, meat and vegetarian, cold and heat balance. Food collocation is closely related to nutritional balance. A bowl of instant noodles can only provide oil, a little protein and carbohydrates, so it is best to match a piece of fruit, a piece of meat or bean products to supplement protein, vitamins and cellulose. For the choice of a day's diet, such as eating hamburgers and fried chicken for lunch, you should eat some light food for dinner, especially vegetables.
