In fact, there are a wide range of drinks. At present, the common drinks on the market can be divided into eight categories: carbonated drinks, fruit juice drinks, vegetable juice drinks, milk-containing drinks, vegetable protein drinks, special functional drinks, bottled drinking water and tea drinks. Because of the different ingredients in the drinks, their nutritional values are different, and their advantages and disadvantages are also different for human health. Here are some examples-generally speaking, aerated "carbonated drinks" contain almost no nutrients except sucrose. Therefore, they are classified as "junk food" by nutritionists. Carbonated drinks are mainly composed of sucrose, carbonate, citric acid, etc., and the fruit juice content is below 2.5%. Most products are blended with artificial flavors and organic acids to produce fruit flavor. 1. Cola beverage: It contains high caffeine, and caffeine is a central stimulant, which can stimulate the increase of gastric acid secretion, make the human brain excited, breathing faster and heart rate faster, so people who often suffer from insomnia should not drink it.

Its main components are sugar, pigment, spices and carbonated water, and there are almost no nutrients except calories. 3. Fruit juice beverage: low in calories, rich in nutrients and rich in taste. Fruit juice is a good source of vitamin C and various mineral elements, and also contains a certain amount of sugar. Pure fruit juice has a high nutritional value, because it is expensive, and it is often not as popular as "fruit juice drink" in the market. Fruit juice beverage contains about 1% pure fruit juice, but other nutrients are low. Because consumers want to get vitamin C from fruit juice drinks, fruit juice beverage manufacturers often add extra vitamin C to their products to improve their nutritional value and also play an antiseptic role. Coconut juice is a natural drink with the highest amino acid content in the world, which contains a lot of plant protein, 17 kinds of amino acids needed by human body and trace elements such as zinc, calcium and iron.

In addition, coconut milk also contains a substance that can kill parasites in the human body, which can make people's blood smooth and their skin rosy. 4, coffee: In addition to caffeine, its nutritional value is not high, it is appropriate to make flavored drinks, and it is best to put milk when drinking. If you are addicted to drinking for a long time, it can cause palpitations and arrhythmia, so you must control it. 5. Beer: A low-alcohol beverage containing carbon dioxide, which is fermented by yeast with barley malt and hops as the main raw materials. Because beer usually contains vitamin B and mineral potassium, it has the functions of appetizing, clearing eyes, invigorating spleen, quenching thirst and diuresis when drunk in moderation. 6. Milk: The most nutritious of all beverages, rich in protein, calcium, phosphorus, vitamins A and B2, etc. Lactose is a carbohydrate contained in milk, which can promote the growth of beneficial microorganisms in human intestines.

Milk is a good source of protein, calcium, vitamin A, vitamin B2, vitamin B6, niacin and vitamin D, and its protein content can reach 3%. 7.

In addition to quenching thirst, diuresis and heatstroke prevention and cooling, regular drinking also has the effects of preventing coronary heart disease and gaining weight loss and bodybuilding. 8. Yogurt: It is made by adding lactic acid bacteria to milk and fermenting at the temperature of insulation. Lactic acid bacteria can improve acidity in human digestive tract, inhibit the reproduction of spoilage bacteria, promote intestinal peristalsis and make stool smooth. Therefore, yogurt is a good nutritious drink, especially suitable for children to drink. Soymilk is a good source of protein, vitamin B1, niacin and many trace elements, and the content of protein can reach 2.5%. Drinking these drinks often is very beneficial to your health. In addition, the nutritional value of peanut milk and walnut milk is close to that of soybean milk. 9. Pure active water: it is a colorless and odorless beverage, which can promote energy release and metabolism. Its osmotic pressure is close to normal saline, which is beneficial to cell absorption, and its ability to dissolve fat is much higher than that of ordinary water. 1. Almond dew, various fruit milk, milk drinks, lactic acid drinks, etc. contain about 1% of protein, and their nutrient content is less than 1/3 of that of milk, so they are also classified as nutritional drinks. Carbonated drinks have no nutrition except sugar; Pure water tastes sweet but does not contain minerals needed by human body. Consumers with increasing health concept are no longer satisfied with the level of quenching thirst. Non-mainstream drinks advertised as healthy: tea, pure fruit juice and functional drinks began to become popular. Tea drinks are refreshing and thirst-quenching, low in price and low in sugar, thus becoming the first non-mainstream "dark horse" to become popular. Pure fruit juice is nutritious, but it seems "a little expensive". Consumers haven't figured it out yet "in fact, its price is not high". Functional drinks, the "function" is still quite attractive, but the taste is still almost-perhaps the people are not used to it.
