Thiamin Functions

• Functions

-helps the body cells convert carbohydrates into energy

-essential for the functioning of the heart, muscles, and nervous system

• It’s found in fortified breads, cereals, pasta, whole grains (especially wheat germ), lean meats (especially pork), fish, dried beans, peas, and soybeans.

• Dairy products, fruits, and vegetables are not very high in thiamine, but when consumed in large amounts, they become a significant source

Deficiency Disease of Thiamin• A deficiency of thiamine can cause weakness,

fatigue, psychosis, and nerve damage• In severe thiamine deficiency, brain damage can

occur• Thiamine deficiency in the United States is most

often seen in those who abuse alcohol (alcoholism). A lot of alcohol makes it hard for the body to absorb thiamine from foods
