Table 1.

Minimum daily consumption (kg) of each of the five most consumed staple crops required to meet the recommended daily amounts (RDA) of thiamine for males, females, and lactating females

Amounts were calculated from the United States Department of Agriculture Food Data Central using recommended daily allowances of thiamine from the World Health Organization. Each crop can be identified using the United States Department of Agriculture National Database Number (NDB number). Amounts were calculated using mg of thiamine per kg of each crop divided by the recommended daily allowance of thiamine (mg).
