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
The delivery platforms of birth spacing and family planning interventions were often associated with health clinics and community health posts (148–150). Many interventions targeted lactating women during the follow-up with their young children (148, 151–153). Home visits by community health workers and service provision at community health posts and mobile clinics were also used to target women and adolescents who were married, and were found to be effective at increasing use of contraception (150, 154). School-based programs were also effective at reaching adolescent girls and increased their knowledge about contraceptives and sexually transmitted infections, use of contraception, and treatment of sexually transmitted infections (155). In high-income settings, school-based interventions were most effective at reducing pregnancies and repeated pregnancies among adolescents when contraception was also available on-site (107). This might have implications for their effectiveness in low- and middle-income countries, as well. In addition, formative work of 2 ongoing studies suggested that mass media, mobile devices, texting, and community mobilization could also be used as platforms to reach adolescent girls and women of reproductive age (156, 157). Community-based programs that target men, families, and communities, beyond those that reach married and postpartum women alone, have potential to change cultural norms and enhance women's health outcomes; however, these are not well captured in the literature.

WASH interventions, such as toilet facilities, access to improved and safe water supply, and hand washing are associated with improved nutrition and health of entire communities (13, 14, 125–128). For women and adolescent girls, WASH interventions were associated with improved menstrual hygiene (126), reduced diarrhea and intestinal worm infections (128–131), and reduced maternal mortality (132). Women and young girls are also more affected by the physical and time burdens of collecting water (126), and harassment and violence associated with inadequate and unsafe toilet facilities (133, 134). Closer water points and sanitation facilities eased these gendered burdens (126, 135). WASH interventions and perceived water availability were associated with less time spent on water-related chores, and improved school attendance, women's empowerment, and self-esteem (126, 135, 136).
WASH interventions were typically community-based. WASH interventions were delivered to households and communities through community mobilization, mass media, home visits, and infrastructural development (126, 130, 136–138). There were some examples of facility-based delivery of WASH interventions, such as in health clinics and schools (139, 140); however, this was not representative of the majority of delivery platform coverage. Health clinic delivery platforms had limited reach, often targeting pregnant women and women with young children. In an evaluation of WASH interventions delivered in India (141), more demanding behavioral practices, such as handwashing and consistent use of latrines, required more intense contact (e.g., multiple home visits) than less intense interventions, such as sweeping of courtyards, that could be effectively delivered in small group meetings such as those in health clinics and community centers. More research is needed to evaluate the benefits and barriers of different delivery platforms for women across the life course.
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.
Health care experts haven't reached a consensus on the issue of vitamin and mineral supplements. Many say that if you are healthy and eat a well-balanced diet, you don't need any. But not all of us eat a well-balanced diet. And sometimes, you may follow a nutritious diet and still be deficient. Many women fail to get the adequate amount of vitamins and minerals. Stress increases your need for vitamins and minerals, especially C, B-complex and zinc.
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.
Sugar is a source of calories, not nutrients. Consuming too much sugar can lead to weight gain and tooth decay. Contrary to what many people think, there is no evidence linking high-sugar diets to hyperactivity or diabetes. However, high-fructose corn syrup, found in most processed foods, is linked with obesity, and obesity increases your risk for developing diabetes and other conditions.
What you eat is even more important as you enter your 40s. Women need protein (meat, fish, dairy, beans, and nuts), carbohydrates (whole grains), fats (healthy oils), vitamins, minerals, and water. These foods have been linked to some disease prevention, such as osteoporosis, high blood pressure, heart disease, diabetes, and certain cancers. The American Academy of Family Physicians supports the development of healthy food supply chains in supplemental nutrition programs so as to broaden the availability of healthy food.
For this comprehensive narrative review, we evaluated both nutrition-specific and nutrition-sensitive interventions. Nutrition-specific approaches are those that address the immediate determinants of nutrition (e.g., food and nutrient intake, diet-related practices and behaviors, disease, etc.), whereas nutrition-sensitive approaches are those that address the underlying determinants of nutrition (e.g., food security, access to resources, safe and hygienic environments, adequate health services, etc.) (5, 12). We evaluated the following nutrition-specific interventions described by Bhutta et al. (13, 14): nutrition counseling and education, micronutrient supplementation and fortification, protein and energy supplementation, and lipid-based supplementation. We also included the following nutrition-sensitive approaches described by Ruel and Alderman (5) and Bhutta et al. (14): health care; family planning; water, sanitation, and hygiene (WASH); empowerment; income-generation; education; and social protection. For each intervention, we 1) described the scale and coverage of the intervention, when available; 2) summarized the evidence of effectiveness for women's health and nutrition outcomes; and 3) described and evaluated the target population and delivery platforms, as described in the published articles and as summarized in Table 1. The delivery of interventions included the physical platforms, as well as the adherence and the implementation challenges of the different interventions.
Instinct may tell you to slow down when running in wintery conditions, but the secret to not slipping is actually to speed up and shorten your stride. Aim to have each foot strike the ground 90 times per minute, says Terry Chiplin, owner of Active at Altitude, a Colorado-based facility for endurance athletes. This high cadence helps ensure that each foot lands beneath the center of your weight rather than ahead of it, which can throw off your balance on slick terrain. 
Before and during pregnancy. You need more of certain nutrients than usual to support your health and your baby’s development. These nutrients include protein, calcium, iron, and folic acid. Many doctors recommend prenatal vitamins or a folic acid supplement during this time. Many health insurance plans also cover folic acid supplements prescribed by your doctor during pregnancy. You also need to avoid some foods, such as certain kinds of fish. Learn more about healthy eating during pregnancy in our Pregnancy section.
“The reason most people don't see changes isn't because they don't work hard—it's because they don't make their workouts harder,” says Adam Bornstein, founder of Born Fitness. His suggestion: Create a challenge every time you exercise. “Use a little more weight, rest five to 10 seconds less between sets, add a few more reps, or do another set. Incorporating these small variations into your routine is a recipe for change,” he says.
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.
