Lunch staple food is best matched with coarse and fine grain.

Many people don't pay much attention to staple food, and some even don't eat staple food at noon, which is very unhealthy. From a nutritional point of view, there should be more than two staple foods for lunch. In other words, in addition to rice, steamed bread and other polished rice noodles, it is best to eat coarse grains, such as sweet potatoes, corn, pumpkins, taro and so on.

Eating more potassium-containing food at noon is not easy to get sleepy in the afternoon.

Lack of potassium in the human body is easy to lead to lack of energy and drowsiness, so we should eat more vegetables rich in potassium for lunch, such as spinach, amaranth, coriander, celery, green onion, green garlic, lettuce, yam, fresh peas and edamame.

In addition, don't eat foods that are too greasy or high in sugar for lunch. These foods will stimulate the secretion of insulin and bile, make the internal organs of the human body overwhelmed, and reduce the oxygen-carrying capacity of the blood, resulting in a decrease in oxygen content in the brain, which makes people easily tired.

3, less oil when cooking, not more than 30 grams per person per day.

4. Avoid eating instant noodles, biscuits, shortcakes, potato chips and other foods with a lot of fat.
