To treat asthma, you can try taking some or all of the following supplements, in addition to what is recommended in the Six Core Principles for Optimal Health: • Vitamin C, 1,000 to 4,000 mg, three to four times a day (has antihista-mine-like activity and supports the adrenal glands). • vitamin a (preformed, not as beta-carotene), up to 50,000 IU a day in divided doses for up to two weeks to help heal mucous membranes and resist infection (do not take over 10,000 IU daily if you are pregnant or if you could become pregnant). • Vitamin B6, 50 to 100 mg three times a day.

These drugs can cause severe headaches when taken with high doses of vitamin a. What Else to Take If You Take These Drugs Supplements of the above nutrients. Be sure to take probiotics during and after a course of antibiotics. See the natural alternatives at the end of the chapter. Other Tips on These Drugs Children under the age of eight should not be given these drugs. During long-term therapy, your physician should periodically monitor your organ systems, including kidney and liver functions and blood chemistry.

Be sure you're getting both beta-carotene and vitamin a in your multivitamin formula. Other Tips on These Drugs They can skew the results of many blood and urine tests. Take them with food or they may upset your stomach. Potassium-Sparing Diuretics Amiloride (Midamor) Spironolactone (Aldactone) Triamterene (Dyrenium) Combinations (Dyazide, Moduretic, Aldactazide, Maxzide) The potassium-sparing diuretics are usually combined with one of the other diuretics to reduce excessive potassium depletion.

They may contain levels of vitamin a that can accumulate to toxic levels in your liver. Omega-6 fats aren't all bad. One such fat, GLA, can also promote good cardiovascular health and help control inflammation, as long as you're maintaining a diet low in hydrogenated oils and refined carbohydrates. You should be taking 50 to 100 times more EPA than GLA. You only need 1 to 2 mg of GLA and 50 to 100 mg of EPA. If you're pregnant or nursing, take in at least 300 mg of DHA per day. Andrew L. Stoll, M.D.

It's also an excellent source of vitamin C and vitamin a, and it contains vitamin Bg and potassium as well. Perhaps most importantly, watermelon has more free-radical-fighting lycopene than any other fresh fruit or vegetable—fewer free radicals, of course, means less cellular damage and slower aging. All in all, watermelon is an ideal featherweight fruit, and it is considered by many to be a perfect diet food. How to use it. Watermelon enthusiasts seem to find no limit to how this versatile fruit can be prepared and consumed.

In India, Navdanya is promoting the sharing of seeds of foods rich in vitamin a. And in Kenya, Karangathe and the Green Belt Movement are introducing gunnysack gardens, so leafy greens again grow within arms' reach of villagers' cooking pots. Seeing Abundance Breaking free from the scarcity ttap, many are seeing abundance where thirty years ago we saw scarcity; resources where before we saw waste. Official UN tallies of food that is actually available tell us we have only 2,000 calories a day for every person on rhe planet—sufficient, but only barely, for us all to survive.

So if we discover problems in this area, we recommend several remedies: the sulfur-containing amino acids, found in foods such as broccoli, brussels sprouts, cabbage, cauliflower, kale, bok choy, garlic, and onion; vitamins, such as vitamin a, vitamins B6 and B12, and folic acid; and/or trace minerals such as magnesium, selenium, zinc, copper, and manganese. Many plant compounds, or phytonutrients, are also powerful detoxifiers, such as those found in silymarin, derived from a milk thistle plant.

Nutritional deficiencies also contribute to oxidative stress—if we're selenium deficient, or if we don't have enough vitamin E or vitamin a or other key antioxidants, we may not be able to supply our body with the needed factors that will keep our antioxidant system working. Being overweight, too, can hurt. Fat tissues produce inflammatory molecules that lead to increased oxidative stress. We find that oxidative stress and inflammation are closely linked. It seems that wherever you find one, you'll find the other.

Blood antioxidant levels: Levels of vitamin a, vitamin E, coenzyme Q10, and beta-carotene can be directly measured in the blood. (1,2) Addressing sludge, burnout, heat, waste, and rust are the backbone of our ultraprevention system. Yet most doctors don't pay attention to any of these forces because they operate under this model: If it ain't broke, don't fix it. The problem is that "it" may well be broken already. But most doctors don't realize this, because they wait until something is damaged almost beyond repair before they act.

Food is a source of nutrients rich in antioxidants, including selenium, vitamin C, vitamin a, and the phytonutrients such as lycopene, xanthine, and lutein. (Phytonutrients are compounds found in plants with positive medicinal effects.) But food is also the biggest source of free radicals, manufactured by oxidative stress. This is because when the body processes food (specifically, when we convert food into usable energy inside our mitochondria), it releases free radicals that need to be quenched by our antioxidant system.

Carotenoids are found in vegetables, and our bodies can convert them into vitamin a. There are many different kinds of carotenoids found in yellow and orange fruits and vegetables. Many of these can now be found as a blend in supplements, including beta- and alpha-carotene, lutein, lycopene, and xeanthin. • Mixed tocopherols (vitamin E): 400 to 800 IU/day. Vitamin E is found in many forms, including d-alpha, gamma, and delta.

A toxicity study of chronic administration of capsicum extract to hamsters reported decreased vitamin a levels in liver tissue and eye toxicity including: a focal increase in corneal epithelial cells, and hyalinisa-tion and thickening of the substantia propria in the eyeballs.77 No similar effects have ever been reported in humans. Other effects which have been reported in humans include: increased fibrinolytic activity and hypocoagulability of blood.78 However, these effects have been reported after ingestion of capsicum in the diet, as opposed to medicinal effects.

It is interesting to note that vitamin a in its full form can be toxic in excessive doses, but beta-carotene in its pre-vitamin A form has never been shown to be toxic at any level. That is why grazing animals can consume so much green grass and not develop hypervitaminosis A. But nature did not anticipate current and projected future levels of UV penetration from the sun. The balance has been tipped. The free radical process occurs as a chain reaction in the molecular structure of the cell when elevated levels of UV stress the plant's ability to protect itself.

IU of vitamin a. While it's great to eat lots of fruit and vegetables, the quality is just as important as the quantity. For this reason, it is best to buy local produce in season and consume it quickly. The worst thing you can do is buy fruit shipped in from the other side of the world and leave it hanging around for two weeks before you eat it. Organic food also tends to have much higher levels of both vitamins and minerals and other antioxidants. VARIATIONS IN NUTRIENT CONTENT IN COMMON FOODS Nutrient Variation (per 3.5 oz.

Beta carotene is a precursor to vitamin a. vitamin a can be toxic in excessively large amounts (50,000 units daily for one year). Arteriosclerosis Caused By Hyperhomocysteinemia And Its Correction Dr. Kilmer McCulley is responsible for the discovering that elevated levels of homocysteine damage arteries. Homocysteine stops the production of the valuable vasodilating nitric acid, causes blood to thicken, and facilitates the oxidation of LDL cholesterol, thus setting the stage for an atherosclerotic plaque to form.

The group estimated that as much as twenty pounds of cooked golden rice a day would be needed to meet the daily requirement of vitamin a. In many undeveloped countries, a pound of rice per person each day is a luxury.8 Even if scientists increased levels of beta-carotene in the rice, people eating it needed enough fat in their bodies to complete the chemical reaction from food to vitamin. Unlike overfed Westerners, most poor people have little chance to add fat to their meager diets.

To anyone living in poverty in, say, the Indian subcontinent, Indonesia, Vietnam, Thailand, or the Philippines, where there are the most severe shortages of vitamin a, the benefit, if true, was seen from a much different angle. However, poor people in these regions should be forgiven for seeing the moment of celebration in Freiburg's botanical gardens as a public relations stunt. Since the first gene-altered whole food had appeared on the market in 1994, not one product had come their way. Bioengineering of crops had passed them by.

Several aid programs were launched to distribute vitamin a capsules, to add iron to wheat flour, and to educate poor people about their diet. But distribution was uneven and often impossible in remote areas. The UN's Food and Agriculture Organization, the World Health Organization, and leading food research groups suggested that the real solution was to increase the amount of the missing nutrients in the staple crops. Potrykus searched in vain for private funds for his rice transformations. None of the private companies was even studying rice.

Olestra traps fat-soluble vitamins like vitamin a, vitamin D, vitamin E, and the antioxidant carotenes that are waiting for passage into circulation during the digestive process. The FDA was worried about the problem this could cause, especially for children, but not worried enough to withhold approval of the material for use in snack foods. The FDA approval was conditional upon Procter & Gamble advising its customers to fortify all foods containing olestra with vitamins A, D, and E. However, no label warning is required to advise consumers of the antivitamin activity of olestra.

Beta-carotene, an essential nutrient for the human body, produces vitamin a. The lack of this vitamin causes the death of an estimated 1 million of Asia's poorest children each year from weakened immune systems. Another 350,000 go blind. Although beta-carotene is present in the leaves of the rice plant and the husk of the grain, which is removed during milling, the pigment had never found its way into the rice grain.
