Strengthening diet has a great influence on our life. For example, eating too much liquid food will make people forget, while pasta and Chinese food will make diners feel tired and sleepy after an hour. To avoid these problems, you can refer to the following nutritional suggestions: eating more dietary fiber can slow down the body's absorption of sugar and make blood sugar rise slowly and steadily. Generally speaking, adults need 25 to 30 grams of fiber every day. Whole wheat food, black beans and apples contain a lot of dietary fiber, so they can also be considered as the content of dinner. Using fatty acids to accelerate fatty acids contained in deep-sea fish, walnuts and mustard oil in the brain can improve the health of brain cells and help you keep a clear head. The importance of adequate water intake to human body is self-evident. If the human body is short of water, the blood will begin to thicken, and nutrients cannot be transported to various organs, and people will feel tired. Therefore, people should drink at least 250 ml of water every two hours to avoid the symptoms of water shortage. If you don't like drinking water, some fruits with high water content are also good choices, such as watermelons and oranges. Avoid taking too much caffeine in the afternoon. Professor Anthony of Harvard Medical School in the United States believes that taking 200-300mg of caffeine every day (the content of caffeine in 2-3 cups of coffee) can make people more energetic. But if you consume too much caffeine in the afternoon, it will seriously affect people's sleep and make you feel extremely tired the next day. Eat breakfast even if you are not hungry. Studies show that people who eat breakfast are better than those who don't, both mentally and physically. Research from Cardiff University in the UK shows that breakfast can help people maintain a low level of stress. Eating something every 2-3 hours and eating one meal less every day can avoid fatigue caused by low blood sugar concentration. It should be noted that adding meals can't keep you eating, because too much digestive burden will make you sleepy. Fish fillets, nuts, yogurt, cereal, etc. Are all good choices. The protein and carbohydrates they contain will increase your blood sugar concentration, make you feel excited and reduce your craving for sweets.
