Vitamin B6 was the only nutrient significantly tied to the symptom score, with lower intake accompanying more severe symptoms; median intake was 0.9 mg a day. - Author: Food Consumer - Tags: Vitamins, Nutrition, Vitamin B6, IBS, #vivvo-import By David Liu A new study published online April 30, 2011 by Nutrition Research suggest vitamin b6 deficiency may result in irritable bowel syndrome (IBS) symptoms. The study led by Solveig C. Ligaardena and Per G. Farup at Innlandet Hospital Trust in Gjøvik, Norway found low intake of vitamin B6 was correlated with more severe irritable bowel syndrome symptoms. The researchers said most subjects in the study with IBS experienced the association between IBS symptoms and foods they ate. They wanted to know which nutrient may be responsible for IBS. In the study, 17 subjects with IBS were asked to record IBS symptoms and foods they consumed daily for a period of seven days and an IBS sum score ranging from 0 to 15 was calculated. B6 is the only vital nutrient that was found significantly associated with the IBS sum score. The median daily intake of vitamin B6 was found at 0.9 mg per day. The researchers said a minimum of 1.6 mg /day recommended for men and 1.2 mg/day for women. A high IBS sum score was linked with low vitamin b6 intake. In the United States, it is recommended that men and women aged 19 to 50 should have intake of 1.3 mg/day of vitamin B6\. For men and women aged 51 or older, the recommended daily dose is 1.7 mg and 1.5 mg respectively. Vitamin b6 benefits Vitamin B6 offers a range of benefits. It helps prevent homocysteine and cardiovascular disease, immune dysfunction, cognitive malfunction, and kidney stones. The vitamin may also be enlisted to treat diseases and conditions including side effects of oral contraceptives, premenstrual syndrome or PMS, depression, morning sickness in pregnancy, and carpal tunnel syndrome. Vitamin b6 foods Foods that are found high in vitamin b6 include fortified cereal, banana, wild salmon, cooked turkey, cooked light chicken meat, baked Russet potato, cooked spinach, dry roasted hazelnuts, and vegetable juice cocktail. Some food cosnumers many want to know this: Potatoes and spinach are two foods that contain highest amounts of pesticides, according to Environmental Working Group. Those who are concerned should buy and use organic ones. Vitamin b6 toxicity Vitamin b6 rich foods are safe to eat while vitamin B6 supplements have been associated with adverse effects. Vitamin b6 is water soluble and it can be excreted in the urine easily, meaning it rarely causes any adverse effect. But long term use of vitamin B6 or pyridoxine at high doses such as 1000 mg per day may result in sensory neuropathy in some people, according to the Linus Pauling Institute.
