The Food and Nutrition Board has set RDAs to prevent iron deficiency. Adequate Intake levels (AI) are set for younger infants, as seen in Table 11-1. Strict

Table 11-1 RDAs and adequate intakes (AI) for iron for all ages.

vegetarians have higher RDAs in some cases to allow for lower absorption. These vegetarian RDAs can be reduced if vitamin C is included in the diet. It is not unusual for vegetarians to consume large amounts of vitamin C, which increases their absorption of dietary iron. Most grain products in the United States are fortified with iron. Despite this fortification, most pregnant and premenopausal women receive less than the RDA for iron in their diet.
