Nutrition interventions that target mothers alone inadequately address women's needs across their lives: during adolescence, pre-conception, and in later years of life. They also fail to capture nulliparous women. The extent to which nutrition interventions effectively reach women throughout the life course is not well-documented. In this comprehensive narrative review, we summarized the impact and delivery platforms of nutrition-specific and nutrition-sensitive interventions targeting adolescent girls, women of reproductive age (non-pregnant, non-lactating), pregnant and lactating women, women with young children<5 years, and older women, with a focus on nutrition interventions delivered in low- and middle-income countries. We found that though there were many effective interventions that targeted women's nutrition, they largely targeted women who were pregnant and lactating or with young children. There were major gaps in the targeting of interventions to older women. For the delivery platforms, community-based settings, compared to facility-based settings, more equitably reached women across the life course, including adolescents, women of reproductive age, and older women. Nutrition-sensitive approaches were more often delivered in community-based settings, however, the evidence of their impact on women's nutritional outcomes was less clear. We also found major research and programming gaps targeting overweight, obesity, and non-communicable disease. We conclude that focused efforts on women during pregnancy and in the first couple of years postpartum fails to address the interrelation and compounding nature of nutritional disadvantages that are perpetuated across many women's lives. In order for policies and interventions to more effectively address inequities faced by women, and not only women as mothers, it is essential that they reflect how, when, and where to engage with women across the life course.
Calories. Most times, women need fewer calories. That’s because women naturally have less muscle, more body fat, and are usually smaller. On average, adult women need between 1,600 and 2,400 calories a day. Women who are more physically active may need more calories. Find out how many calories you need each day, based on your age, height, weight, and activity level.
Iron: Essential for healthy blood cells, iron becomes especially important when girls begin to menstruate. With each period, a woman loses small amounts of iron. “About 10% of American women are iron deficient,” says Dorothy Klimis-Zacas, PhD, a professor of nutrition at the University of Maine and co-editor of Nutritional Concerns of Women (CRC Press, 2003). “About 5% have iron deficiency anemia.” Symptoms of low iron include fatigue, impaired immunity, and poor performance at school or work.
Healthy eating is a way of eating that improves your health and helps prevent disease. It means choosing different types of healthy food from all of the food groups (fruits, vegetables, grains, dairy, and proteins), most of the time, in the correct amounts for you. Healthy eating also means not eating a lot of foods with added sugar, sodium (salt), and saturated and trans fats.

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., .
Nutrition is particularly important during pregnancy to ensure your health and the health of the baby. It's normal to gain weight during pregnancy—not just because of the growing fetus, but because you'll need stored fat for breast-feeding. The Institute of Medicine (IOM) recommends a gain of 25 to 35 pounds in women of normal weight when they get pregnant; 28 to 40 pounds in underweight women; and at least 15 pounds in women who are overweight when they get pregnant. The IOM has not given a recommendation for an upper limit for obese women, but some experts cap it as low as 13 pounds. If you fit into this category, discuss how much weight you should gain with your health care professional.
Salt, caffeine and alcohol intake may interfere with the balance of calcium in the body by affecting the absorption of calcium and increasing the amount lost in the urine. Moderate alcohol intake (one to two standard drinks per day) and moderate tea, coffee and caffeine-containing drinks (no more than six cups per day) are recommended. Avoid adding salt at the table and in cooking
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.
