If you do decide to diet, you still need to maintain good nutrition. You want to cut back on calories, not nutrients. And while you want to reduce fat, don't eliminate it entirely. Some studies suggest that older women who maintain a higher body-fat percentage are less likely to suffer from osteoporosis and other conditions associated with menopause. Fat cells also retain estrogen, which helps maintain the calcium in your bones. Younger women should be careful, too: a low body fat percentage can lead to infertility; below 17 percent may lead to missed periods, also known as amenorrhea.
In the past, women have often tried to make up deficits in their diet though the use of vitamins and supplements. However, while supplements can be a useful safeguard against occasional nutrient shortfalls, they can’t compensate for an unbalanced or unhealthy diet. To ensure you get all the nutrients you need from the food you eat, try to aim for a diet rich in fruit, vegetables, quality protein, healthy fats, and low in processed, fried, and sugary foods.
In addition, more research is needed to evaluate the impact of targeting women alone compared with targeting women alongside other members of their families and communities (e.g., with groups of other women, men, husbands, children, parents, in-laws, other family members, other community members, etc.). Interventions that targeted women with their children during child health visits or alongside other members of their communities through community mobilization and mass media campaigns showed improvements in knowledge and some health and nutrition behaviors of women. The inclusion of boys and men, for instance, as well as the inclusion of other family and community members, could enhance the impact and delivery of nutrition interventions for women through support of certain practices, reminders, time-savings, and normalization of nutrition behaviors. However, more research is needed to identify effective targeting mechanisms (i.e., alone or alongside other members of households and communities) and we expect that these will likely need to be context- and content-specific.
For healthy bones and teeth, women need to eat a variety of calcium-rich foods every day. Calcium keeps bones strong and helps to reduce the risk for osteoporosis, a bone disease in which the bones become weak and break easily. Some calcium-rich foods include low-fat or fat-free milk, yogurt and cheese, sardines, tofu (if made with calcium sulfate) and calcium-fortified foods including juices and cereals. Adequate amounts of vitamin D also are important, and the need for both calcium and vitamin D increases as women get older. Good sources of vitamin D include fatty fish, such as salmon, eggs and fortified foods and beverages, such as some yogurts and juices.
Even if you are the most independent exerciser around, give a group fitness class a shot at least once a week—you may find that you enjoy it more than sweating solo. “Happiness and health are shared through social connectedness and closeness,” says Greg Chertok, director of sport psychology at the Physical Medicine and Rehabilitation Center in New Jersey. “Geography and proximity are predictors of how contagious emotions can be, and this may translate into an athletic environment too.” Sign up for Bikram, CrossFit, spin, or Zumba, and you could find yourself—gasp!—smiling at the gym thanks to your classmates.
Vinyasa and power may not be the only forms of yoga that will get you closer to that long, lean, limber look. Research presented at the 73rd Scientific Sessions of the American Diabetes Association found that restorative yoga—which focuses more on relaxing and stress-reducing movements rather than a challenging flow or balancing poses—burns more subcutaneous fat (the kind directly under your skin) than stretching does. By the end of the yearlong study, yogis who practiced at least once a month lost an average of about three pounds, nearly double the amount lost by those who only stretched. So if you don’t feel up for a more athletic yoga class, ease your way into a practice with a gentle one.
We only included studies that reported on women's health and nutrition outcomes, and excluded studies that were targeted to women but that reported only on health and nutrition outcomes of children (including birth outcomes). We included outcomes for adolescent girls ages 10–19 y, pregnant and lactating women, nonpregnant and nonlactating women of reproductive age (>19 y), and older women. Studies that described interventions targeting a wider age range of adolescent girls (e.g., ages 8–24 y) were also included but adolescent girls aged >19 y were reported in this review as nonpregnant and nonlactating women of reproductive age. Although many adolescents in low- and middle-income countries are married and bearing children, adolescents (10–19 y) as reported in this review reflect girls who are nonpregnant and nonlactating. The few interventions in low- and middle-income countries that target pregnant and lactating adolescents are reported under pregnant and lactating women. A description of the articles included in this review can be found in Supplemental Table 1.
It has not been scientifically established that large amounts of vitamins and minerals or dietary supplements help prevent or treat health problems or slow the aging process. Daily multivitamin tablets can be beneficial to some people who do not consume a balanced diet or a variety of foods. Generally, eating a well-balanced diet with a variety of foods provides the necessary nutrients your body needs. Eating whole foods is preferable to supplements because foods provide dietary fiber and other nutritional benefits that supplements do not. If you choose to take vitamin and mineral supplements, it is recommended to choose a multi-vitamin that does not exceed 100 percent of the Recommended Dietary Intake (RDI).
Getting enough water also is important. Many experts recommend at least eight 8-ounce glasses of water daily—more if you exercise frequently or are exposed to extremes of heat and cold. The 2010 Dietary Guidelines for Americans emphasize drinking more water and other calorie-free beverages, along with fat-free or low-fat milk and 100 percent fruit juices, instead of calorie-packed regular sodas.
All of the identified studies focused on LNSs for pregnant and lactating women through antenatal care–based and –affiliated delivery platforms (97–101). These studies relied on antenatal care to recruit mothers but delivered the intervention through home visits. There was no evidence evaluating use of LNSs for women who were not pregnant or lactating. The majority of studies evaluating LNS interventions involved children with severe or moderate acute malnutrition. Although LNS supplementation could be an intervention to provide essential nutrients to women and girls, it is expensive. Filling energy gaps using local foods or other commodities can often be done at a lower cost (97). LNS supplementation should be limited to contexts in which cheaper, more sustainable solutions are not available.
Folic acid: This form of B vitamin helps prevent neural tube defects, especially spina bifida and anencephaly. These defects can be devastating and fatal. Many foods are now fortified with folic acid. Most women get enough as part of their diet through foods such as leafy greens, a rich source of folic acid. However, some doctors recommend that women take a pregnancy supplement that includes folic acid, just to make sure they are getting the recommended 400 to 800 micrograms.
A year later, a second Harvard study added to the concern. The Physicians' Health Study of 20,885 men did not evaluate diet per se, but it did measure the blood levels of ALA in 120 men who developed prostate cancer and compared them with the levels in 120 men who remained free of the disease. Men with moderately high ALA blood levels were 3.4 times more likely to develop prostate cancer than men with the lowest levels; curiously, though, men with the very highest levels were only 2 times more likely to get the disease.
For some simple suggestions about eating a healthy, balanced diet, check out the "New American Plate Concept" from the American Institute for Cancer Research. This concept suggests you fill your plate with two-thirds or more of vegetables, fruits, whole grains or beans and only one-third or less of animal protein. This simple principle can guide you toward healthier eating. For more details, visit http://www.aicr.org/site/PageServer?pagename=reduce_diet_new_american_plate.
Low-fat diets also can help you lose weight.16 But the amount of weight lost is usually small. You can lose weight and lower your risk for heart disease and stroke if you follow an overall healthy pattern of eating that includes more fruits, vegetables, whole grains and beans that are high in fiber, nuts, low-fat dairy and fish, in addition to staying away from trans fat and saturated fat.

Animal products, such as meat, fish and poultry are good and important sources of iron. Iron from plant sources are found in peas and beans, spinach and other green leafy vegetables, potatoes, and whole-grain and iron-fortified cereal products. The addition of even relatively small amounts of meat or foods containing vitamin C substantially increases the total amount of iron absorbed from the entire meal.
The guidelines also establish ranges (called acceptable macronutrient distribution ranges or AMDR) for fat, carbohydrates and protein, instead of exact percentages of calories or numbers of grams. The report maintains that since all three categories serve as sources of energy, they can, to some extent, substitute for one another in providing calories.
