Deficiency is not common in U.S.

In general, people who live in developed countries like the United States get enough thiamin. However, those suffering from eating disorders or living in poverty may not be eating enough food to get sufficient thiamin in their diet.

Although there are some excellent sources of thiamin, many foods contain small amounts of thiamin. If you eat a variety of foods from all of the food groups, you will more than likely get enough thiamin.

Some are more susceptible

Alcoholics are at particular risk for thiamin deficiency, since alcohol inhibits the ability of the body to absorb thiamin. This means that even if an alcoholic is eating a thiamin-rich diet, the body may not have access to enough of this B vitamin to maintain good health.

In addition, when alcohol is replacing food in the diet, there could also be a thiamin deficiency.

When you need more of this B vitamin

You should know that the need for thiamin is greater under certain conditions:



-Adolescent growth

-Strenuous exercise


-Consuming large amounts of coffee

-Frequent use of diuretics
