What About Fortified Foods
Some juices and ready-to-eat cereals have vitamin C added. The amount of vitamin C added to each product will vary. Check the nutrition label to see how much vitamin C the product will contribute to your daily diet. Always choose 100% fruit juice over fortified fruit drinks. Although they might be fortified with vitamin C, they lack the other vitamins and minerals that fruits and vegetables supply.
What Does Recommended Daily Allowance Mean
The recommended daily allowance for vitamins and minerals is the average daily intake a person needs to avoid deficiencies and stay healthy. Men and women often have different vitamin and mineral recommendations.
There are different ways to measure the RDA. Vitamins and minerals that are needed in larger doses are measured in milligrams and those that the body needs less of are measured in micrograms. There are 1,000 micrograms in 1 milligram. Each vitamin and mineral has a specific RDA.
Vitamin C And The Body
Vitamin C enables the body to efficiently use carbohydrates, fats, and protein. Because vitamin C acts as an antioxidant a nutrient that chemically binds and neutralizes the tissue-damaging effects of substances known as free radicals it is vital to the growth and health of bones, teeth, gums, ligaments, and blood vessels. Vitamin C also plays a key role in the formation of collagen, the bodys major building protein, and is therefore essential to the proper functioning of all internal organs.
Vitamin C is found in various foods, including citrus fruits such as oranges, lemons, and grapefruit in green vegetables such as spinach, broccoli, and cabbage and in tomatoes and potatoes. Food processing may degrade or destroy vitamin C, as can exposure to air, drying, salting, cooking , or processing.
In modern times, access to fresh fruits and vegetables is common, rendering full-blown cases of vitamin C deficiency relatively rare. Cases are normally limited to isolated elderly adults, usually men whose diet is limited to foods lacking in vitamin C, as well as to infants fed reconstituted milk or milk substitutes without a vitamin C or orange juice supplement. Those with certain illnesses, such as AIDS, cancer or tuberculosis, surgical patients, and those exposed to long periods of cold temperatures can also suffer from vitamin C insufficiency.
How Vitamin C Supports A Healthy Immune System
Vitamin C, or ascorbic acid, is a water-soluble vitamin well known for its role in supporting a healthy immune system. Because your body cannot make vitamin C, it must come from the foods you eat every day.
Research shows vitamin C is essential for the growth and repair of tissue all over the body. Vitamin C helps heal wounds and repair and maintain healthy bones, teeth, skin and cartilage a type of firm tissue that covers the bones. As an antioxidant, vitamin C fights free radicals in the body which may help prevent or delay certain cancers and heart disease and promote healthy aging. Vitamin C from foods also seems to reduce the risk of cartilage loss in those with osteoarthritis.
Though it may not keep you from catching a cold, there is some evidence that high doses of vitamin C may decrease the length of cold symptoms by as much as one to one-and-a-half days for some people. However, other studies did not result in the same findings, and the risk of side effects is greater with high doses of vitamin C supplements, so check with your doctor or registered dietitian nutritionist before taking.

Ascorbate is found in the lens of the eye. Studies have shown that supplementation with just 2g of vitamin C per day was associated with a nearly 40-fold increase in lens ascorbate . In the Nutrition Vision Project , a subset of the Nurses’ Health Study, showed that women aged 60 years, with consumption of at least 363mg/day vitamin C was associated with a 57% decreased risk of developing a cortical cataract compared with women who consumed less than 140mg/day vitamin C .

Nobel Prize winner Linus Pauling was first to suggest that vitamin C has a profound effect on the immune system. He suggested two possible effects: first, high doses of vitamin C would be greatly beneficial for cancer patients, even curative second, regular supplementation could decrease the number of colds per year. Though both hypotheses have been disputed by the scientific community, Paulings work can be seen as the foundation for what we know about vitamin C today.The common coldPrevention of the common cold is the most widely perceived benefit of vitamin C. Pauling suggested that 1 to 2 g of daily vitamin C would substantially strengthen the immune system, reducing frequency of the common cold. While much interest exists in this theory, researchers have found that vitamin C helps shorten the duration of a cold rather than decrease the number of colds per year.
