What is Beta Carotene? Its Advantages?

What is Beta Carotene?

Beta-carotene is one of a group of red, orange, and yellow pigments called carotenoids. Beta-carotene and other carotenoids provide approximately 50% of the vitamin A needed in the American diet. Beta-carotene can be found in fruits, vegetables, and whole grains. It can also be made in a laboratory.

Beta-carotene is used to decrease asthma symptoms caused by exercise; to prevent certain cancers, heart disease, cataracts, and age related macular degeneration (AMD); and to treat AIDS, alcoholism, Alzheimer’s disease, depression, epilepsy, headache, heartburn, high blood pressure, infertility, Parkinson’s disease, rheumatoid arthritis, schizophrenia, and skin disorders including psoriasis and vitiligo.

Beta-carotene is also in used in malnourished (underfed) women to reduce the chance of death and night blindness during pregnancy, as well as diarrhea and fever after giving birth.

Some people who sunburn easily, including those with an inherited disease called erythropoietic protoporphyria (EPP), use beta-carotene to reduce the risk of sunburn.

There are many authorities – including the American Heart Association, the American Cancer Society, the World Cancer Research Institute in association with the American Institute for Cancer Research, and the World Health Organization’s International Agency for Research on Cancer – that recommend getting beta-carotene and other antioxidants from food instead of supplements, at least until research finds out whether supplements offer the same benefits. Eating 5 servings of fruits and vegetables daily provides 6-8 mg of beta-carotene.

How effective is it?

Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate.

The effectiveness ratings for BETA-CAROTENE are as follows:

Effective for...

• Treating sun sensitivity in people who have a form of inherited blood disorder called “erythropoietic protoporphyria.”

Possibly effective for...

• Reducing the risk of breast cancer in women before menopause when fruits and vegetables containing beta-carotene are consumed. Beta-carotene seems to be especially effective for women who are at high risk of getting breast cancer, including those with a family history and those who use alcohol excessively.
• Treating an eye disease called age-related macular degeneration (AMD) when used with other medicines. Taking 15 mg of beta-carotene by mouth along with 500 mg of vitamin C, 400 IU of vitamin E, and 80 mg of elemental zinc daily, seems to help prevent vision loss and worsening of AMD in people with advanced AMD. There isn’t enough evidence to know if this combination works for people with less advanced macular disease.
• Preventing sunburn in people who are sun sensitive. However, beta-carotene is unlikely to have much effect on sunburn risk in most people.
• Keeping a form of arthritis called osteoarthritis from getting worse. But taking beta-carotene doesn’t seem to prevent osteoarthritis.
• Preventing bronchitis and difficulty breathing in smokers. Beta-carotene from the diet seems to help, but beta-carotene supplements do not.
• Reducing the risk of ovarian cancer in women after menopause.
• Reducing the risk of pregnancy-related death, night blindness, and diarrhea and fever after delivery in underfed women.
• Preventing asthma attacks triggered by exercise.
• Treating a tongue disease called oral leukoplakia.
• Improving physical performance and strength in the elderly.

Beta-carotene is converted to vitamin A, an essential nutrient. It has antioxidant activity, which helps to protect cells from damage.

Are there safety concerns?

Beta-carotene is LIKELY SAFE when used for certain specific medical conditions and taken in appropriate amounts. However, beta-carotene supplements are not recommended for general use.

Beta-carotene is POSSIBLY UNSAFE in high doses, especially when taken long-term. High doses of beta-carotene can turn skin yellow or orange.

There is growing concern that taking high doses of antioxidant supplements such as beta-carotene might do more harm than good. Some research shows that taking high doses of beta-carotene supplements might increase the chance of death from all causes and possibly other serious side effects. There is also concern that taking large amounts of a multivitamin plus a separate beta-carotene supplement increases the chance of developing advanced prostate cancer in men.

All About Vitamin A

All About Vitamin A

Vitamin A was first discovered back in 1912, by a Polish biochemist named Casimir Funk. He came up with the word vitamine, which was later given the name vitamin. Funk was the first to discover vitamins as we know them today, although vitamin A was actually the first one discovered, hence the letter “A” in the title of the vitamin.

You can find vitamin A in natural foods such as oranges and yellow fruits. It can also be found in vegetables as well, such as spinach and fats. When found in vegetables, vitamin A is water soluble, coming in the form of beta carotene. The beta carotene form of vitamin A can be eliminated from your body through natural processes, making it an excellent way to get vitamin A.

Vitamin A is required by the body on an every day basis to maintain healthy skin and keep your eyesight on track. There are many people who say that carrots provide enough vitamin A to prevent you from getting night blindness. The fact is, ancient Egyptian doctors prescribed liver in their time, which they said contained enough vitamin A to combat night blindness. Vitamin A is also known as an antioxidant, which makes it ideal to prevent cancer and anti aging. Along with these benefits, it also helps with your immune system as well.

To get the proper absorption of vitamin A, you’ll need to consume fat. Those of you who happen to be on a low fat or restricted diet, simply may not be getting the right amounts of vitamin A from your supplements that you may think. To get the proper absorption of vitamin A in your diet, you’ll need to consume a high enough level of protein. Protein combines with vitamin A to make it stronger, and help it move through your body.

On a normal day, you should be consuming around 5,000 international units (IU) of vitamin A. Depending on your health and your age, you may need to consume more or less. The safest form of vitamin A is beta carotene as mentioned above, and it can be taken in much larger doses. No matter what age you may be, you can feel safe to consume high amounts of vitamin A in the form of beta carotene.

If you don’t consume enough vitamin A in your diet, you’ll end up with a deficiency. A deficiency is never a good thing, as it normally results in skin problems, increased infections, and even night blindness as well. A prolonged deficiency in vitamin A can put you at a risk for cancer as well, and you’ll also miss out on any effects of anti aging that the vitamin might have. Although you should begin taking it immediately if you have a deficiency, the effects wouldn’t be the same as they would be if you stayed up to date with the right amount on a daily basis.

On the other hand, if you are getting too much vitamin A, you’ll put yourself at risk for pain in your joints, abdomen, and your bones. Even though too much or not enough can cause you serious side effects, you should always get the right amount in your diet. Vitamin A is very important, and should always be included in your diet. You can find it in many foods, or take supplements that include the well needed vitamin. If you are going to take supplements, you should make sure that they provide the right amounts - with no side effects.
