1, infant?

Infants and young children are in a vigorous period of growth and development, so we should pay attention to supplementing rich protein and calcium, and try to eat less food with high sugar content to prevent dental caries and obesity. When conditions permit, children usually have a glass of milk, an egg and a bun for breakfast. Of course, sometimes juice or porridge can be used instead of milk, or biscuits or steamed bread can be used instead of bread.

2. teenagers?

The body develops rapidly in adolescence, which is an important period for the growth of muscles and bones. It is necessary to supplement sufficient nutrients such as calcium, iron, vitamin C and vitamin A, especially to ensure adequate intake of calories to meet the needs of teenagers' physical and mental activities. A reasonable breakfast for teenagers is100g of cereal, a glass of milk, an egg and some fresh fruits or vegetables.

3. Middle-aged people?

When people reach middle age, their physiological functions gradually decline and their basal metabolic rate decreases, but at the same time, middle-aged people are in a busy period of career and family. Breakfast should not only meet the nutritional needs, but also prevent some diseases.

The diet of these people should not only be rich in protein, vitamins, calcium and phosphorus, but also be low in calories and fat, and the intake of carbohydrates should be properly controlled. The ideal breakfast for middle-aged people is: an egg (or tofu, sauce meat), a bowl of soybean milk or a bowl of porridge, a small amount of dry food (steamed bread, pie, biscuits, bread) and a proper amount of vegetables.

The misunderstanding of eating breakfast

1, a roadside stall to buy breakfast?

Office workers spend their mornings in a hurry, and breakfast is often solved on the way. Next to the stalls selling steamed stuffed buns, tea eggs, steamed stuffed buns and pancake fruit near the bus station, you will often see many people patronizing. Eating while walking is not conducive to digestion and absorption, and street food often has health hazards.

Choose sweets

Eating too sweet snacks for breakfast is unhealthy. Too much sugar in breakfast makes people feel hungry. At the same time, the fat and a lot of sugar contained in butter and cream make people inadvertently consume too much energy, which leads to obesity. So try not to choose too sweet food as the staple food for breakfast.
