LMany people like to drink a can of Red Bull after exercising, thinking that it can replenish energy. Moreover, when sports drinks are advertised, they often like to present a look of vitality and exercise, which makes people think that sports drinks are healthy drinks and they can drink them casually. But is this really the case?
Natalie Rizzo, American nutritionist and founder of Nutrition à la Natalie, recently shared some tidbits about sports drinks.
Rizzo points out that sports drinks are only really needed for people who have been exercising for a long time, or who have been exposed to the hot sun. Those who are sedentary, or who exercise little, should not drink such beverages because they contain too much sugar.
A lot of water will be lost during exercise, and drinking water is the simplest and most direct source for human beings to replenish water, but sometimes, simply drinking water cannot meet the needs of the body. For example, a white residue on your skin after sweating could be a sign that your body is losing sodium, while feeling dizzy, tired, having a headache, or a racing heart could be the result of dehydration, a lack of water and electrolytes in your body . Therefore, during exercise or work, you should drink two sips of sports drinks from time to time, and drink more after exercise.
There are also energy bars similar to it. If you want to know, there are so many energy bars on the market, but not all of them are healthy energy bars.
Generally, for people who are active outdoors or who are prone to sweating, they need to drink some sports drinks in about 30 minutes. If sweating is less, then replenish after about 45 minutes.
The ingredients in sports drinks mainly include the following:
One is to contain the electrolytes needed by the human body. While sweating, the human body will lose some minerals, such as sodium, calcium, magnesium and potassium, which are electrolytes that play a decisive role in maintaining the osmotic pressure of extracellular fluid and the distribution and transfer of body fluid. Proper supplementation of electrolytes is of great significance to maintain body water.
The second is sugar. Sugar provides energy as a carbohydrate, and the body stores sugar in the muscles and liver, called glycogen, and uses these carbohydrates absorbed and stored during diet as a source of energy for exercise. However, these glycogen in the human body can only be maintained for about 1 hour, and then it needs to be replaced to obtain more energy.
The third is salt. Since the main component of sweat is sodium, you lose about 1 gram of sodium per liter of sweat lost. In the hot summer, you will inevitably sweat a lot after exercising, so you can’t simply replenish water, and sodium supplementation is also necessary.
But the above are only the main ingredients of most sports drinks, and more attention should be paid to specific brands. Some sports drinks use high fructose syrup or artificial flavor additives. In contrast, choose drinks containing natural ingredients such as sucrose and glucose, which are easier for the body to absorb.
