Fiber is an important part of an overall healthy eating plan. Good sources of fiber include fortified cereal, many whole-grain breads, beans, fruits (especially berries), dark green leafy vegetables, all types of squash, and nuts. Look on the Nutrition Facts label for fiber content in processed foods like cereals and breads. Use the search tool on this USDA page to find the amount of fiber in whole foods like fruits and vegetables.
Women and men have approximately equal risk of dying from cancer, which accounts for about a quarter of all deaths, and is the second leading cause of death. However the relative incidence of different cancers varies between women and men. In the United States the three commonest types of cancer of women in 2012 were lung, breast and colorectal cancers. In addition other important cancers in women, in order of importance, are ovarian, uterine (including endometrial and cervical cancers (Gronowski and Schindler, Table III).[6][120] Similar figures were reported in 2016.[121] While cancer death rates rose rapidly during the twentieth century, the increase was less and later in women due to differences in smoking rates. More recently cancer death rates have started to decline as the use of tobacco becomes less common. Between 1991 and 2012, the death rate in women declined by 19% (less than in men). In the early twentieth century death from uterine (uterine body and cervix) cancers was the leading cause of cancer death in women, who had a higher cancer mortality than men. From the 1930s onwards, uterine cancer deaths declined, primarily due to lower death rates from cervical cancer following the availability of the Papanicolaou (Pap) screening test. This resulted in an overall reduction of cancer deaths in women between the 1940s and 1970s, when rising rates of lung cancer led to an overall increase. By the 1950s the decline in uterine cancer left breast cancer as the leading cause of cancer death till it was overtaken by lung cancer in the 1980s. All three cancers (lung, breast, uterus) are now declining in cancer death rates (Siegel et al. Figure 8),[121] but more women die from lung cancer every year than from breast, ovarian, and uterine cancers combined. Overall about 20% of people found to have lung cancer are never smokers, yet amongst nonsmoking women the risk of developing lung cancer is three times greater than amongst men who never smoked.[119]
Nutrition education, including communication and counseling to raise awareness and promote nutrition-related knowledge and behaviors aligned with public health goals, was found to increase women's knowledge and improve women's dietary diversity and protein intake (15–21). It also reduced energy intake of overweight women over a 9-mo period (22). However, evidence for the effectiveness of nutrition education interventions showed mixed impact on biological and anthropometric markers of women's nutritional status (14–16, 18, 23–29). This could be due to lack of statistical power given the small sample sizes of the reviewed studies. For adolescent girls, nutrition education was found to reduce odds of overweight, and improve knowledge, dietary intake, physical activity, and sedentary behavior (27, 29, 30). This was particularly true for nutrition education that lasted longer than 12 mo (29). Nutrition education was also more strongly associated with changes in health outcomes in studies evaluating childhood obesity treatment, rather than childhood obesity prevention (29).
Infertility means not being able to get pregnant after one year of trying (or six months if a woman is 35 or older). Women who can get pregnant but are unable to stay pregnant may also be infertile. About 10 percent of women (6.1 million) in the United States ages 15-44 have difficulty getting pregnant or staying pregnant, according to the Centers for Disease Control and Prevention (CDC).

During adolescence and early adulthood, women need to consume foods rich in calcium to build peak (maximum) bone mass. This will reduce the risk of developing osteoporosis, a progressive condition where there is a loss of bone that leaves those affected more susceptible to fractures. Women also need an adequate iron intake because they lose iron through menstruation. Women also need an adequate intake of calories to support energy and nutritional needs in order for the body to function properly. The amount of calories that an individual needs varies for each person and is based on age, gender and activity level. As a general recommendation, women between 23 and 50 years of age generally need between 1,700 and 2,200 calories per day to maintain their current energy needs and body weight. Older women generally require fewer calories to support and sustain energy needs. Consuming fewer than 1,500 calories per day, even in attempts to lose weight, can put women at nutritional risk and can result in malnutrition and poor health.

The 2005 Dietary Guidelines for Americans is another reference or guide to assist you in learning to eat a balanced and nutritious diet for good health.
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.
