In its natural state, sugar is a relatively harmless — even necessary — carbohydrate our bodies need to function. It’s found in fruits, vegetables and dairy as the compound fructose or lactose. The problem comes when sugar is added to foods during processing for added flavor, texture or color. Eating too many of these empty calories has many health effects, the most obvious being major weight gain. Added sugar drives your insulin levels up, messes with your metabolism and causes those calories to turn right into belly fat. Sugar goes by many names. Learn more about the surprising benefits of cutting back on sugar.
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., .
Omega-3 fatty acids — essential to health and happiness, reviewed by Dr. Mary James, MD. From conception to old age, every cell in our bodies needs omega-3’s. Learn how omega-3 fatty acids benefit every body system — from the brain to the heart, breast, bones, colon, skin and more, this is one nutrient that can make all the difference to our health, our happiness, and — perhaps best of all — our longevity.
Here, too, body size is the main difference between the needs of males and females. Despite all the hype about high-protein diets, our protein requirements are really quite modest — only about a third of a gram per pound of body weight. For a 125-pound woman, that amounts to about 42 grams, for a 175-pound man, 58 grams. That's a tiny difference, just about half an ounce a day.
There's not much doubt about this one: Women need more iron than men, because they lose iron with each menstrual period. After menopause, of course, the gap closes. The RDA of iron for premenopausal women is 18 mg a day, for men 8 mg. Men should avoid excess iron. In the presence of an abnormal gene, it can lead to harmful deposits in various organs (hemochromatosis). Since red meat is the richest dietary source of iron, it's just as well that men don't need to wolf down lots of saturated fat to get a lot of iron.
"Studies show that omega-3 fatty acids are cardio-protective and the basis for the AHA recommendation to consume fatty fish twice weekly," she says. "But the studies do not show that popping a supplement can have the same benefit in healthy individuals." She adds, "There is also a misperception that fish oils can lower cholesterol, but this is not true."

Medicine companies follow FDA regulations. Some makers of dietary supplements follow the U.S. Pharmacopeial (USP) Convention quality standards. This means they volunteer to have their products tested. An outside company will check them for quality and purity before they are sold. These supplements display additional credentials on their labels. Look for them to say “USP Verified” or “ConsumerLab.com Approved Quality.”
