                                An estimated 80% of individuals with chronic alcohol abuse will develop a thiamine deficiency, but alcohol is not the only cause.  Beyond this well-known factor, several types of foods, beverages, and specific dietary patterns can also contribute to a decrease in vitamin B1 (thiamine) levels in your body. This happens either by containing thiaminase enzymes that destroy the vitamin or by increasing the body's metabolic demand for it.
