High-fat and high-sugar foods can easily stimulate the secretion of insulin and bile, overburdening the body's internal organs and reducing the blood's oxygen-carrying capacity. This leads to lower oxygen levels in the brain, making one feel easily tired. Such foods include fast food items like french fries, hamburgers, and fried chicken, as well as foods like steamed buns and pork.
1. Eat more vegetarian food. Green, high-fiber vegetables, such as chili peppers, carrots, and spinach, can ensure that brain cells receive sufficient oxygen, keeping you energetic all afternoon. Lunches consisting of protein and vegetables, such as fresh fish, chicken, seafood, and tofu, contain large amounts of tyrosine, which plays a decisive role in keeping the mind sharp, enhancing memory, and maintaining alertness;
2. Choose mung bean rice or whole wheat bread as your staple food;
3. Follow a certain order when eating: eat meat first, then vegetables, and finally the staple food.
4. Don't eat too much for lunch. Eat until you are about 70% full. After eating, get some light exercise and do not rest immediately.
5. Supplement more vitamins. During work breaks, eat fruits rich in vitamins, such as pineapple, oranges, and lemons, to eliminate nervous system fatigue and boost energy.
6. Be mindful of foods that can easily cause drowsiness. Bananas and sunflower seeds have a suppressive effect on brain activity and can easily lead to drowsiness, so it's best to avoid them.
