In order to improve the body’s immunity, some young office workers used to add a vitamin C effervescent tablets in the water every day, not only delicious, but also to enjoy the wonderful bubbles bared up and down tumbling fun. The weather is gradually turning colder and colder, and respiratory diseases are more and more frequent, especially among people with colds. In order to improve the body’s immunity, some young office workers are used to adding a vitamin C tablet to their water every day, which is not only delicious, but also enjoys the wonderful bubbles tumbling up and down. Convenient, tasty and rich in vitamin C, effervescent tablets are loved by many young people, but can it actually be consumed for a long time? Many people know that vitamin C tablets can supplement vitamin C, which generally contains vitamin C, citric acid, sodium bicarbonate and so on. This reporter visited some supermarkets and pharmacies in Chengdu and found that recent sales of Vitamin C effervescent tablets were much higher than in previous months, and most purchasers treated them as a health product rather than a drug. The sales staff said that the price of vitamin C effervescent tablets is not expensive, ranging from a dozen to dozens of yuan, a box can be soaked for a while, “many customers buy to prevent colds.” ”sweet and sour, than the general health care products are much better, and into the water, can produce up and down bared bubbles, the dissolution process is like releasing vitality.” Miss Zhang, who works in an institution, will soak up a tablet every now and then, “and convenient and can supplement vitamin C, always better than drinking carbonated drinks.” Vitamin C effervescent tablets into the water, the rapid disintegration, the reaction between the citric acid and sodium bicarbonate, the production of carbon dioxide, can not be dissolved in the water of carbon dioxide will run out, the formation of many bubbles. Since there are many benefits, can vitamin C effervescent tablets be consumed for a long time? In this regard, Li Hongyu, deputy director of the Department of Nutrition at Chengdu Second Hospital, said, “One of the main functions of effervescent tablets is to increase vitamin C, which cannot directly prevent colds. And effervescent tablets are chemically synthesized flushes, which may cause side effects when consumed daily.” Generally speaking, a daily intake of 30 mg of vitamin C can meet the body’s metabolic needs, and 100 mg is already a pharmacological dose. Do not overdose on vitamin C because it tastes good as a drink, and do not take more than 100 mg a day. Oral intake of large doses of vitamin C can bring side effects to the human body, which may cause nausea, vomiting, diarrhea, abdominal pain, rashes and other symptoms; and can lead to an increase in vitamin C metabolites oxalic acid, which can cause urinary stones; overdose of vitamin C may also affect the body’s immune system. At the same time, the human body has not only vitamin C, but also vitamins A, B, D, E and so on. And the human body is a balanced organism thanks to its pattern of mutual equilibrium among various elements. Artificially making a certain element increase will lead to an imbalance in the body, but affect the human health. There are four major misconceptions: 1. Boiling water for effervescent tablets Put vitamin C effervescent tablets in very hot water, and wait for it to dissolve while the water will slowly cool. In fact, vitamin C in hot water above 80 ℃, there will be a certain loss of, very easy to be oxidation decomposition. Therefore, the best way is to brew with warm water at about 40 ℃. 2, a cup of effervescent water drink too long Some people are afraid of trouble, will brew a cup of vitamin C effervescent tablets may drink a morning. In fact, too long exposure in the air will also lose vitamin C. Each time with about 200 ml of plain water or mineral water can be, in order to drink as soon as possible, and to now bubble now drink. 3, effervescent tablets and other drinks mixed with the practice of mixed drinking is also not advisable. Some studies have shown that the theophylline and other ingredients contained in tea will react chemically with vitamin C or disintegrants. The sodium benzoate in the drink reacts with the vitamin C and may produce harmful benzene substances. 4, after drinking without brushing your teeth In order to reduce the stimulation and damage of vitamin C effervescent tablets on the teeth, it is recommended to rinse your mouth after taking, and also try to avoid taking vitamin C effervescent tablets before bedtime and before and after brushing your teeth, and people with sensitive teeth should pay more attention.
