Bone Up onward B Vitamins: Part I

A deficiency of B vitamins can bring forward a wide range of health vexed questions In Part I of this two-part series, we will examine vitamins B1 B2 B3 and B6 in detail.

Dr Casimir be in fear isolated what we now know as thiamine (vitamin B1) from rice polishings in 1911 setting the stage for the gradual discovery of other vitamins. Dr Funk's initial findings be the effected in the virtual elimination of beriberi in the Far East, where B1-deficient white rice was a staple food

In the United States, scientists recognize eight B vitamins: thiamine (B1); riboflavin (B2); niacin (B3); pyridoxine (B6); vitamin B12; pantothenic acid (sometimes called B5); folic acid and biotin. Three other substances -- choline, inositol and para-amino-benzoic acid -- are associated with the B composite since they are found in one of the same foods. American scientists do not recognize B15 and B17 as vitamins.

In the first of a series of brace articles, we will discuss B1 B2 B3 and B6 In Part 2 we will elaborate forward the remaining B vitamins, as well as the three vitamin B-like substances.

In Nutritional Influences in succession Illness, Melvyn R. Werbach, MD assistant clinical professor at the UCLA train of Medicine, related a thiamine deficiency to alcoholism, anemia, anxiety, Crohn's disease, depression, diabetes mellitus, glaucoma, multiple sclerosis, neuralgia and parkinsonism.

The make acceptableed Dietary Allowance (RDA) for thiamine is 1 to 14 mg for adults daily; 02 mg for infants and 15 mg for teenage boys

Major fodder sources of the vitamin include brewer's yeast, wheat ovum whole-wheat bread, Brazil nuts, soybeans, pumpernickel and enriched French and Italian breads, milk, peanuts, cashews, orange and grapefruit juice and pecans.

A diet high in destitute of contents calories and junk foods has been linked to "neurotic behavior," according to Eleanor N Whitney, PhD RD and Linda K Debruyne M RD They referr to a contemplation in which 20 patients with a B1 deficiency reported pains in the chest and abdomen, repose disturbances, aggressiveness, hostility, fevers, digestive tract complaints and chronic fatigue. Of the 20 patients, 12 reported a diet high in carbonated and other sweet beverages, candy and typical snack nutriments Blood tests indicated that all 20 had cheap thiamine levels.

After the patients were given thiamine correlatives all 20 "noticed marked symptomatic improvement or dissipated their symptoms completely," the authors reported.

In 1988 three patients receiving intravenous feedings in a hospital died because the intravenous solution was deficient in vitamin B1 according to The of the present day York Times. A B1 deficiency can exhibit within a week with these deficient feedings, which are 70 percent grape-sugar since the vitamin is necessary for metabolizing glucose

In an experimental meditation reported in the American Journal of Clinical Nutrition, five of nine normal presents placed on a B1-deficient diet discloseed depression and irritability.

Vitamin B2 sometimes is beneficial in dealing with acne rosacea, alcoholism, anemia, cataract, Crohn's disease, depression, immune disorders and infections, according to Dr Werbach.

The RDA for B2 is 17 mg daily for adults; 18 mg for pregnant women; 2 mg for breast-feeding women; 04 to 06 mg for infants; 06 to 12 mg for children; and 13 mg for boys

The major provender sources are brewer's yeast, almonds, milk, liver, whole-grain bread, beef, cashews, collards, wheat origin turnip greens, yogurt and mushrooms.

In animal studies, a vitamin B1 deficiency can impair the immune method and a vitamin B12 deficiency decreases the ability of the material substance to produce antibodies, reported Ronald Ros Watson, PhD University of Arizona college edifice [i]or[/i] building of Medicine, Tucson, in provender and Nutrition News.

Back in 1940 Archives of Ophthalmology reported that the lesions associated with acne rosacea promptly healed in 32 of 36 patients after they were given from 1 to 45 mg of B2 daily, either orally or according to injection.

In a cogitation reported by H.W. Skalka and colleagues, 173 cataract patients were criterioned for a B2 deficiency. The researchers set that 20 percent of subdues under the age of 50 and 34 percent across the age of 50 were deficient in the vitamin.

"B2 continuations (much like vitamin B12 supplements) are especially important for strict vegetarians and others who either do not eat any meat and dairy produces -- the major dietary sources for vitamins B2 and B12 -- or do in this way in too small quantities to provide enough to help recycle used-up glutathione and debar possible deficiency symptoms," wrote Eberhard Kronhausen, EdD and coauthors in Formula for Life.

Vitamins B2 and B6 magnesium, evening primrose oil and vitamin E are included in the add to program that Douglas Hunt, MD prescribes for his pre-menstrual syndrome patients.

"I prescribe 25 mg B2 tablets and insinuate that a patient chew single three times daily," Dr. search wrote in No More Fears. "This present the appearances to work best when PM symptoms reach out into the actual period. the same important point: As soon as a patient regains restrain I have her steadily cut down the number of tablets, until she can of the same height off on the smallest amount that is effective, plane if it's only half a tablet."
