Are sports drinks scientific?

 　　Powerful, Gatorade, Red Bull, there are a lot of high-energy drinks on the market that dazzle people. Can these drinks play their role in replenishing energy? Do they say the ingredients in energy drinks are backed by science?

　　Although we need to replenish energy after exercise, drinking energy drinks is not the best way. There is no scientific basis to support the merchant's remarks. Most of the energy comes from the sugar and coffee because. Therefore these drinks are usually very high in calories. In addition, general energy drinks also contain ginseng, vitamins, green tea, etc. The bad thing is that the so-called high-tech formulas contained in many energy drinks are actually not only useless but also harmful to the human body, such as trace elements such as technetium. But it's difficult to measure how much of these stimulants are in drinks. It is generally not marked on the label, and even if it is marked, it is difficult for consumers to judge whether it is harmful to the human body based on it. A cup of coffee contains 125-250 mg of caffeine, a can of cola contains 35-38 mg, and a can of energy drink contains 280 mg. For one cup, the human body can consume up to 200-300 mg of caffeine per day.

　　When drinking energy drinks, people will unknowingly consume too much sugar, caffeine, etc., and many stimulants will also have great side effects on the human body. People may know how much caffeine they consume will not affect their physical condition, but those stimulants are different, and they do not even know what side effects they have. The doctor said that possible side effects are nausea, leg weakness, palpitations, nerve Allergies, nervousness, etc. Drinking on an empty stomach may cause greater side effects. It can also cause over-excitement, difficulty concentrating, difficulty sleeping, nausea, abnormal blood pressure, etc.

　　Don't think that drinking an energy drink before exercise will make you more energetic. Instead, it raises your blood pressure and stimulates your heart and nervous system. Energy drinks can also produce the same side effects as medications, and the consequences cannot be underestimated. If you have heart disease or high blood pressure, avoid all stimulating drinks.

　　If you do need something to replenish your strength and energy, coffee with skim milk is a better choice because we know more about caffeine. It is also recommended that you only drink a maximum of two or three cups of caffeinated drinks per day, and it is best to eat something else when drinking. If you find caffeine too stimulating, try decaf coffee or a semi-caffeinated drink. Other drinks such as juice, low-fat milk and water can also help you replenish your energy. Dehydration can easily lead to fatigue.
