Not everyone who is underweight suffers from an eating disorder, but anorexia and bulimia are serious health problems in this country; an estimated 500,000 women suffer from anorexia, and 1 to 2 million women struggle with bulimia. Women with anorexia nervosa starve themselves and/or exercise excessively, losing anywhere from 15 percent to 60 percent of their normal body weight. Some die. Women with bulimia nervosa binge on large quantities of food—up to 20,000 calories at one time—and then try to get rid of the excess calories. Some purge by inducing vomiting, abusing laxatives and diuretics or by taking enemas. Others fast or exercise to extremes.
Obviously, the best treatment plan for poor nutrition is to change your diet. Most Americans eat too little of what they need and too much of that they don't. For many women, decreasing fat and sugar consumption and increasing fruit, vegetables and grains in your diet can make a big difference. Many women also need to boost consumption of foods containing fiber, calcium and folic acid. Compare your diet to that suggested by the food pyramid and compare your nutrient intake to the suggested daily levels. Adjust accordingly, and you may be able to dramatically improve your health.
Dairy. Women should get 3 cups of dairy each day, but most women get only half that amount.6 If you can’t drink milk, try to eat low-fat plain yogurt or low-fat cheese. Dairy products are among the best food sources of the mineral calcium, but some vegetables such as kale and broccoli also have calcium, as do some fortified foods such as fortified soymilk, fortified cereals, and many fruit juices. Most girls ages 9 to 18 and women older than 50 need more calcium for good bone health.
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). Similar figures were reported in 2016. 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), 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.
The average woman should get 10 to 35 percent of her daily calories from protein. Protein helps prevent muscle tissue from breaking down and repairs body tissues. Sources of animal proteins include meat, fish, poultry, eggs, milk and cheese. Vegetable proteins include dried beans and peas, peanut butter, nuts, bread and cereal. (A three-ounce serving of cooked chicken contains about 21 grams of protein.)
A 55-year-old woman who gets less than 30 minutes of daily physical activity should eat five ounces of grains; two cups of vegetables; one and a half cups of fruit; three cups of milk; five ounces of meat and beans; five teaspoons of oils, and no more than 130 calories of additional fat and sugar. If she got 30 to 60 minutes of daily exercise, she could increase her intake to six ounces of grains; two and a half cups of vegetables; and up to 265 additional calories of fat and sugar.
