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).
Women's nutrition is often eclipsed by maternal nutrition. There are important linkages between maternal nutrition and the health, cognitive development, and earning potential of future generations (1). However, with reduced childbearing and longer life spans, women's experiences extend beyond motherhood (2). Interventions and policies that target women solely as mothers fail to account for women before they conceive, after they no longer engage with programs targeting maternal–child health, as well as those who never have children (3, 4). A woman's nutrition should matter not (only) because of her reproductive potential, but because it is fundamental to her rights as a person and to her well-being and ability to thrive (5–7). With increasing attention to the nutritional needs of adolescent girls (8, 9), in addition to the rising prevalence of overweight, obesity, and noncommunicable disease affecting women later in life (10), it is becoming more imperative that interventions reach women at all life stages.
Not being able to do a pull-up doesn’t mean you shouldn’t step up to the bar. Simply hanging on for as long as possible can improve your upper-body strength, Montenegro says. Concentrate on keeping your body as still as possible, and you’ll naturally recruit your abs, hips, and lower back in addition to your arms, she explains, or slowly move your legs in circles or up and down to further engage your abs. 
The U.S. Public Health Service recommends that all women of childbearing age consume 400 mcg of folic acid (a B vitamin) daily to reduce their risk of having a pregnancy affected with spina bifida or other neural-tube defects. Women who are actively trying to get pregnant should consume 600 mcg, and lactating women should consumer 500 mcg. Women of childbearing age should also take care to meet the daily requirements for calcium, fiber, iron, protein and vitamin D. Discuss supplements with a health care professional, however. Iron and vitamin D in particular can be dangerous in high amounts.
Complementing income-generating interventions with interventions that more directly target women's nutrition has potential to have greater impacts on women's nutritional status (171). Integrated interventions were associated with improvements in health knowledge and behaviors, as well as increased intake of nutrient-rich foods (5, 164, 169, 170, 172). In Bangladesh and Cambodia, the aforementioned EHFP program was associated with increased income, decision-making power in the household, food expenditure (including on oils, salts, spices, fish, rice, and meat), and consumption of fruits and vegetables from home gardens (160, 173). There was also limited, but mixed, evidence of income-generating interventions and behavior change communication causing improvements in maternal anemia and BMI (164, 168, 170).
Women, as we age, are also more susceptible to the breakdown of our bones, which may result in osteoporosis over time. Genetically, women have a particularly high risk of osteoporosis compared to men, so it’s recommended that women monitor their calcium intake to be sure they’re getting enough. Weight training is another great way (and my favorite!) to build bone density, which is another great reason you should hit the weights!

Omega-3s: These essential fatty acids, EPA and DHA, play many roles in the body, including building healthy brain and nerve cells. Some studies show that omega-3s, especially DHA, can help prevent preterm births. Even women who don't plan to have children should be sure to get plenty of omega-3s. These healthy oils have been shown to reduce the risk of heart disease, the number one killer of women.
