Speaking of vitamin C, everyone must be familiar with it.
Since it was discovered that vitamin C can prevent and treat ascorbic acid deficiency (also known as scurvy), more benefits of vitamin C have gradually been discovered, such as enhancing immunity and protecting cardiovascular system.
In addition to these, what other magical effects do you know of vitamin C?
Vitamin C Can Prevent Cold: False
Have you ever taken vitamin C supplements or eaten a lot of oranges to treat your cold after being knocked down by a cold?
Or, during the season of high incidence of colds, take vitamin C supplements to prevent colds?
However, the therapeutic effect of vitamin C on colds is negligible.
Some studies have shown that long-term use of vitamin C supplements may shorten the course of colds or alleviate symptoms. However, for most people, neither stuttering oranges nor taking vitamin C supplements orally has the effect of preventing or treating colds.
Vitamin C does help us maintain normal immune function and ensure wound healing. However, it is futile to rely solely on increasing vitamin C intake to enhance immunity. Adhering to a healthy diet and moderate exercise are the key to maintaining immunity.
The food with the most vitamin C is citrus fruit: fake
It is true that citrus fruits, such as oranges, oranges, grapefruit and lemons, contain more vitamin C. But in fact, many other foods are more rich in vitamin C, including kiwi fruit, chili, various wild vegetables, wild jujube, etc.
For example, kiwi fruit contains nearly twice as much vitamin C as oranges, while wild jujube contains nearly 30 times as much vitamin C as oranges. Other foods rich in vitamin C include broccoli, strawberries, fresh jujube, papaya, etc.
No matter how much vitamin C you take, you won’t be poisoned: fake
Our bodies cannot store vitamin C. If we take too much vitamin C, the body mainly excrets it through urine. However, this does not mean that excessive intake of vitamin C will not endanger our health.
The maximum daily tolerable dose of vitamin C is 2000 mg (including the intake of food and health products). If the daily intake of vitamin C exceeds this dose, some people may suffer from poisoning symptoms such as abdominal distension and diarrhea.
Although vitamin C has many benefits, like other nutrients, the more the better. It is wise to take the right amount.
It doesn’t matter to eat a little less vitamin C: fake
Because our bodies cannot produce vitamin C on their own, we must eat foods containing vitamin C to maintain normal physiological functions.
In the era of great navigation, ascorbic acid deficiency (also known as scurvy) caused by vitamin C deficiency left a deep impression on people. People with scurvy will suffer from rough skin, gingival hemorrhage, epistaxis, skin ecchymosis, gingivitis, osteoporosis and other symptoms.
In modern society, scurvy caused by vitamin C deficiency is very rare. A medium-sized orange contains about 70 mg of vitamin C, which is enough to prevent scurvy. Therefore, if you eat normally, the average person seldom suffers from vitamin C deficiency.
However, this does not mean that it doesn’t matter to eat less vitamin C. We recommend that adults take 100 mg of vitamin C per day. If the intake of vitamin C is increased to 200 mg per day, it can effectively protect cardiovascular diseases and prevent chronic diseases such as coronary heart disease, stroke and cancer.
It is recommended that everyone eat 300 ~ 500 g of vegetables and 200 ~ 350 g of fresh fruits every day to ensure adequate vitamin C intake.
