When women reach childbearing age, they need to eat enough folate (or folic acid) to help decrease the risk of birth defects. The requirement for women who are not pregnant is 400 micrograms (mcg) per day. Including adequate amounts of foods that naturally contain folate, such as citrus fruits, leafy greens, beans and peas will help increase your intake of this B vitamin. There also are many foods that are fortified with folic acid, such as breakfast cereals, some rices and breads.  Eating a variety of foods is recommended to help meet nutrient needs, but a dietary supplement with folic acid also may be necessary. This is especially true for women who are pregnant or breast-feeding, since their daily need for folate is higher, 600 mcg and 500 mcg per day, respectively. Be sure to check with your physician or a registered dietitian nutritionist before taking any supplements., .

Trans fatty acids, also known as trans fats, are solid fats produced artificially by heating liquid vegetable oils in the presence of metal catalysts and hydrogen. They also pose a health risk, increasing LDL or "bad" cholesterol and increasing your risk of coronary heart disease. They are often found in cookies, crackers, icing and stick margarine, and in small amounts in meats and dairy products. Beginning in January 2006, all food manufacturers had to list the amount of trans fatty acids in foods, resulting in a significant reduction in the amount of these fats used in prepared foods. In its guidelines, the American Heart Association notes that trans fats increase risk of heart disease by raising "bad" LDL cholesterol and should be avoided as much as possible. In addition, research has shown that trans fats can also decrease "good" HDL cholesterol, increase inflammation, disrupt normal endothelial cell function and possibly interfere with the metabolism of other important fats—even more evidence that they are very bad for overall health.

Omega-3s: These essential fatty acids, EPA and DHA, play many roles in the body, including building healthy brain and nerve cells. Some studies show that omega-3s, especially DHA, can help prevent preterm births. Even women who don't plan to have children should be sure to get plenty of omega-3s. These healthy oils have been shown to reduce the risk of heart disease, the number one killer of women.
