Final answer:
The primary sources of folate in the American diet are enriched cereals, bread, and grains, along with seafood, organ meats, nuts, and legumes, among others. Folate is vital for preventing birth defects, hence women of child-bearing age should ensure adequate intake.
Step-by-step explanation:
The primary sources of folate in the American diet are enriched ready-to-eat cereals, bread, and grain products. Folate is also found in other foods such as seafood, organ meats, nuts, legumes, chocolate, and some fruits and vegetables including broccoli and asparagus. It is important for women who might become pregnant to consume at least 400 µg/day of folate from supplements or fortified foods to help prevent birth defects such as neural tube defects that can occur early in pregnancy.
Other sources that contribute to folate intake include brewer's yeast, almonds, milk, and additional nutrient-rich foods like spinach and lettuce which are green leafy vegetables. Foods from the meat group like chicken and fish, as well as various vegetables and fruits, are also beneficial for their folate content.
