People with good health will naturally have good energy. First of all, you should have a strong liver. The liver is an important chemical plant in the human body, which has two major functions: one is to convert and store energy, and the other is to detoxify. People with poor liver function must have poor energy. Secondly, you should have a healthy stomach. Whether three meals a day can be digested, absorbed and utilized is closely related to the stomach. If the gastrointestinal function is not good, what you eat in a day will be difficult to be absorbed and utilized, and people will have no energy. Then you must have a strong heart and blood vessels. When the heart and blood vessels are strong, all kinds of nutrients and oxygen needed by the human body can be transported smoothly, and energy is naturally no problem. Let's talk about these main ones first.
