Lowering The Risk Of Some Cancers
Vitamin C is an antioxidant, so it can prevent damage caused by free radicals. This may help prevent diseases such as cancer.
Investigations into whether vitamin C effectively prevents cancer have yielded mixed findings. However, the results of a few studies have been positive:
- A meta-analysis found that vitamin C was linked to a lower risk of certain types of brain tumor.
Some people may need higher amounts of vitamin C than others. People who smoke or are exposed to secondhand smoke, for example, may require more vitamin C to reduce the damage of the free radicals that the smoke releases.
Other groups who may benefit from a higher vitamin C intake include:
- people who do not eat enough fruits and vegetables or who have a very restricted diet
- people who are unable to fully absorb vitamins and nutrients
- people with certain health conditions, such as kidney disease or cancer
If someone cannot get enough vitamin C in their diet, they can take supplements. Many brands are available in drug stores and online.

Why You Need Vitamin C
Vitamin C is involved in the development and function of various body parts. It helps your body produce essential compounds that help your nerves, heart, brain, and muscles function and your body produce energy.
Vitamin C also helps restore antioxidants in your body. Antioxidants prevent cell damage that can lead to diseases. It also helps your body metabolise protein and absorb iron.
Adults aged 19 to 64 need about 40 milligrams of vitamin C a day. If you eat the right foods, you can easily get your daily value from your regular diet.
Although vitamin C deficiency is relatively rare, it can lead to the disease called scurvy. Symptoms of scurvy include:
- Fatigue
- Severe joint of leg pain
- Swollen, bleeding gums
- Red or blue spots on your skin
- Your skin bruising easily
On the other hand, too much Vitamin C may cause stomach pain and other digestion issues. However, overdose of the vitamin is not a concern as it is not stored in your body.
Some health benefits of Vitamin C are:
Wound Healing
Vitamin C is needed for the biosynthesis of collagen, which is a protein that is an essential component of connective tissue. Because of this, Vitamin C plays an important role in wound healing.
Immune Function
Vitamin C contributes to immune defense against disease and infections. Vitamin C deficiency impairs your immune system and increases your risk of getting infections.
Are There Any Fruits That Have No Vitamin C
No, fruit juices do in fact contain most of the vitamin C from the fruits. Vitamin C is water-soluble, and most of it remains with the liquid when it is squeezed out of the fruit. The problem is that sugar is also very water-soluble, so the juice also contains most of the sugar from the fruit, with little or none of the fiber.

Dirt Poor: Have Fruits And Vegetables Become Less Nutritious
Because of soil depletion, crops grown decades ago were much richer in vitamins and minerals than the varieties most of us get today
Dear EarthTalk: Whats the nutritional difference between the carrot I ate in 1970 and one I eat today? Ive heard that that theres very little nutrition left. Is that true?Esther G., Newark, N.J.
It would be overkill to say that the carrot you eat today has very little nutrition in itespecially compared to some of the other less healthy foods you likely also eatbut it is true that fruits and vegetables grown decades ago were much richer in vitamins and minerals than the varieties most of us get today. The main culprit in this disturbing nutritional trend is soil depletion: Modern intensive agricultural methods have stripped increasing amounts of nutrients from the soil in which the food we eat grows. Sadly, each successive generation of fast-growing, pest-resistant carrot is truly less good for you than the one before.
What can be done? The key to healthier produce is healthier soil. Alternating fields between growing seasons to give land time to restore would be one important step. Also, foregoing pesticides and fertilizers in favor of organic growing methods is good for the soil, the produce and its consumers. Those who want to get the most nutritious fruits and vegetables should buy regularly from local organic farmers.
Meat Seafood And Dairy Foods
Most meat, poultry and seafood options are vitamin K-free or low in vitamin K. Pork doesn’t contain vitamin K, except for certain types of ham, which contain just trace amounts. A 3-ounce portion of beef round trimmed to remove all the fat and beef tripe, kidneys, heart and brains are also vitamin K-free. Seafood choices for those trying to avoid vitamin K include scallops, halibut, rockfish, lobster, eel and tuna. Egg whites are also vitamin K-free, as are skim milk, nonfat yogurt, 2 percent cottage cheese, fat-free ice cream, reduced-fat American cheese and fat-free cream cheese.

Whole Food Vitamins: Ascorbic Acid Is Not Vitamin C
Whole Food Vitamins: Ascorbic Acid Is Not Vitamin C
by Timothy OShea, medical researcher
Without further ado, heres the kernel: ascorbic acid is not vitamin C. Alpha tocopherol is not vitamin E. Retinoic acid is not vitamin A. And so on through the other vitamins. Vast sums of money have been expended to make these myths part of Conventional Wisdom. If you have several college degrees and all this is news to you, dont feel bad. Unless you think your education ended at Commencement. Which is generally true.
Wheels Within Wheels
Vitamins are not individual molecular compounds. Vitamins are biological complexes. They are multi-step biochemical interactions whose action is dependent upon a number of variables within the biological terrain. Vitamin activity only takes place when all conditions are met within that environment, and when all co-factors and components of the entire vitamin complex are present and working together. Vitamin activity is even more than the sum of all those parts it also involves timing.
Vitamins cannot be isolated from their complexes and still perform their specific life functions within the cells. When isolated into artificial commercial forms, like ascorbic acid, these purified synthetics act as drugs in the body. They are no longer vitamins, and to call them such is inaccurate.

For men over 18, the University of Maryland Medical Center recommends 90 mg of vitamin C daily 1. For women over 18, 75 mg of vitamin C is recommended.
