Vitamin C may also help cure common colds.

It also works as an antioxidant, helping to prevent damage from free radicals. These free radicals are molecules that are produced when the body breaks down food or against exposure to tobacco smoke and radiation. They are the cause of aging, and can be factors that cause diseases such as cancer, heart disease or arthritis.

On the other hand, some of the vegetables with the highest amount of vitamin C are broccoli, cauliflower, peppers, spinach, white potatoes or tomatoes.

Vitamin C can also be found in several vitamin supplements, including multivitamins, although it is also usually found individually.

Pregnant women also need a higher dose of vitamin C daily: 80 mg is needed for adolescent girls. a day, while adults require 85 mg. For those breastfeeding, the amounts are 115 mg. for teenagers or 120 mg. for adults.

Vitamin C benefits:
Vitamin C prevents scurvy and would also be effective in preventing some types of cancer and cardiovascular diseases.

There are several types of cancer that could be prevented if a diet high in vitamin C acquired through fruits and vegetables is maintained, such as colon cancer, lung cancer or breast cancer. However, once the cancer is under treatment, the effectiveness of vitamin C has not been proven. In the same way, cardiovascular diseases tend to be less frequent in those whose dose of vitamin C is recommended, although it has not been scientifically proven.

Vitamin C itself has proven effective against scurvy, which is why it is called "antiscorbutic vitamin." Although this disease is rare today, it can be contracted by those who consume vitamin C in little or no amount for several days. Its symptoms are fatigue, gum inflammation, skin spots or joint pain, among others. If scurvy is not treated in time it can be deadly.

As a popular belief, it is often said that vitamin C also serves as a remedy to cure common colds. However, not all experts agree on the real effectiveness of this remedy. What is certain is that vitamin C can help reduce the duration of the cold, although everything depends on the living conditions of each person. In any case, vitamin C does not prevent catching a cold, but it can help you recover.

Excess vitamin C can be harmful, as it can cause diarrhea, nausea and pain. In addition, it can interfere negatively if taken at the same time as other antioxidants or in cancer treatments.
