Is it good to take natural vitamin C?

The human body needs to supplement enough vitamin C. In addition to dietary intake of vitamin C, many people also supplement vitamin C through medicines, such as eating grapes, apples, kiwis and other foods frequently. Many people will supplement vitamin C blindly, which will cause great harm to the human body. Vitamin C must be supplemented scientifically to be good for human health. Is it good to eat natural vitamin C? Let’s take a look at it next.

1. Is it good to take natural vitamin C?

You can take the drug for a period of time and then stop for a period of time. Generally speaking, vitamins are basically harmless to the body as long as they are not taken in excess. Vitamin C preparations, such as 50-100 mg per day, will not have side effects as a dietary supplement, but large doses, such as 2~3g per day, will cause scurvy after discontinuation of the drug, and occasionally may cause urate, cysteine ​​or oxalate stones and other diseases. When taking vitamin E preparations at normal doses for a long time, you should pay attention to supplementing vitamin A, because vitamin E can promote the absorption and utilization of vitamin A, leading to vitamin A deficiency. The side effects of long-term use of large doses are common breast hypertrophy, headache, dizziness, vertigo, blurred vision, muscle weakness, and more serious thrombophlebitis or pulmonary embolism may also occur.

2. What are the foods rich in vitamin C?

Fruits such as lemons, oranges, tangerines, kiwis, strawberries, etc. are high in vitamin C. Most green leafy vegetables, cabbage, green peppers, etc. are rich in vitamin C. The vegetable with the most vitamin C is broccoli, also known as green cauliflower. It is the king of vitamin C in the vegetable world, with a vitamin C content about 6 times more than that of tomatoes. Try not to fry it when eating it. Eat it cold or in a hot pot so as not to destroy its vitamin C content.

Kiwi is known as the king of vitamin C; followed by dates and papaya; tomatoes and peppers among fruits and vegetables are rich in vitamin C. It is recommended to eat more than 250 grams per day. Don't worry about overdose, because vitamin C is a water-soluble element, excess vitamin C will be excreted through urine and sweat. Because it is easily lost, you must consume it every day and don't think that taking a single vitamin C snack will last for many days.

3. What causes loss of vitamin C?

Modern families generally have refrigerators, and many people like to buy a lot of fruits and put them in refrigerators, but this is not good because the longer the fruit is stored, the more vitamin C is lost.

In addition, smoking can hinder the body's absorption of vitamin C, and the nicotine in tobacco can also destroy vitamin C. Therefore, it is easy to be deficient in vitamin C. People who engage in strenuous exercise or heavy physical labor can also lose a lot of vitamin C due to sweating. Some diseases and drugs can also affect the absorption of vitamin C.

Therefore, fruit cannot be used as the only source of vitamin C for the human body. Vitamin C tablets should be taken when necessary.
