Nutrition for Every Woman at Every Life Stage

Women have unique nutritional needs compared to men — and these needs change throughout the various stages of life. Women, on average, are shorter and weigh less than men, so this accounts for some of the uniqueness. Yet, while women need fewer calories than men, they typically require more vitamins and minerals.
Many factors, including different hormone levels, reproductive considerations, metabolic differences and more, mean women and girls have special nutritional requirements for optimal health. Let’s discuss some of these needs and explain how to adjust accordingly.
Nutrition and Bone Health
Due to a decrease in estrogen levels during menopause — a hormone that helps maintain strong bones — and biologically smaller and thinner bones, women are at a higher risk for osteoporosis, a condition in which the bones become fragile and weak. In fact, the Bone Health and Osteoporosis Foundation reports that of the estimated 10 million Americans with osteoporosis, approximately 80% of them are women. Regardless of age and whether pre- or post-menopausal, osteoporosis can be prevented by getting enough vitamin D and calcium through a well-balanced diet. These are two nutrients that work together to help form and maintain strong bones. Calcium is particularly essential, as not getting enough through food will cause previously stored calcium to be taken from the bones, further causing bone weakness.
Here are quality food sources for these nutrients:
Vitamin D: fish, egg yolks, fortified dairy products or milk alternatives, fortified cereals, fortified orange juice
Recommended intakes:
Women 19-70yo: 15 mcg (600 IU) vitamin D/day
Women >70yo: 20 mcg (800 IU) vitamin D/day
Example: 1 cup of dairy milk contains ~3mcg (120 IU) vitamin D/day
Calcium: milk, yogurt, cheese, fortified milk alternatives, fortified orange juice, fortified cereals, tofu, salmon (particularly canned), green leafy vegetables
Recommended intakes:
Women 19-50yo: 1000 mg calcium/day
Women 50+yo: 1200 mg calcium/day
Example: 1 cup of dairy milk contains ~300 mg of calcium
Iron and Anemia
Due to menstruation, women must consume more iron when pre-menopausal. Iron is an essential nutrient that helps form hemoglobin, the protein in red blood cells that carries oxygen all around our body, as well as myoglobin, the protein that carries oxygen to muscle. When iron levels get too low in the body, this can lead to iron deficiency anemia, a condition where the body doesn’t have enough healthy red blood cells. This often results in symptoms like fatigue, lack of energy and brain fog.
Iron occurs in two forms in food: heme and non-heme iron. Plant foods only contain non-heme iron, whereas animal products contain both non-heme and heme iron. Because heme iron is more easily absorbed and used in the body than non-heme iron, vegetarians and vegans must be more conscious of ensuring they are getting enough iron through diet or supplementation, especially if they menstruate.
There are not established iron recommended dietary allowances (RDAs) for vegetarians and vegans, but per the National Institutes of Health (NIH), needs are estimated to be 1.8 times more than those of meat eaters.
Iron absorption can be increased in the body when eaten alongside vitamin C-containing foods, such as citrus fruits, peppers, tomatoes and strawberries. Good sources of iron include the following:
Heme iron (animal products): lean red meats, seafood – particularly oysters, clams, shrimp, sardines, poultry
Non-heme iron (plant-based products): tofu, fortified cereals, beans, spinach, lentils
Recommended intakes:
Women 19-50yo: 18 mg iron/day
Vegetarian/Vegan Women 19-50yo: ~32 mg iron/day (approximated)
Pregnant Women: 27 mg iron/day
Pregnant Vegetarian/Vegan Women: ~49 mg iron/day (approximated)
Women 51+yo: 8 mg iron/day
Vegetarian/Vegan Women 51+: ~14 mg iron/day (approximated)
Example: 3oz of oysters provides ~8 mg iron
Nutrition for Menopause
As previously mentioned, menopause carries greater risk for osteoporosis, as well as increased risk of weight gain and heart disease. Current research indicates that making lifestyle changes when menopause starts can be significant in reducing some of these risks. In addition to frequently eating foods high in vitamin D and calcium, some of the recommended diet changes include:
- Increasing consumption of fruits and vegetables
- Getting fats from heart-healthy sources like olive oil, canola oil, fatty fish, nuts, seeds and avocados
- Limiting saturated fat from red meats, full-fat dairy products like butter or cream, fried foods and processed meats
- Choosing whole grain carbohydrates like whole wheat bread, brown or wild rice, quinoa and whole wheat pasta
- Reducing added sugars
- Limiting sodium
In addition to these broad recommendations, a few individual nutrients have been studied for potential symptom improvement for menopause. Completed research includes a type of plant compound called phytoestrogens. Phytoestrogens are typically broken into two classes: isoflavones, found primarily in soy, and lignans, found in flaxseed, whole grains, legumes, fruits, and vegetables. While the research has been inconclusive, some evidence suggest that increasing consumption of phytoestrogens may reduce frequency of hot flashes. Additional studies also indicate that omega-3 fatty acids, found in fatty fish, such as salmon, mackerel, sardines, walnuts or flaxseed, could improve menopause symptoms, but more research is needed. Either way, whether these foods do truly produce measurable improvement in menopause symptoms, they are highly nutritious foods that can only improve your overall health.
Help Yourself to Vitamin and Mineral-Rich Foods
To ensure you are meeting your unique nutritional needs and putting yourself in the best position for good health, consider adding more of the foods mentioned above. If you are concerned about potential vitamin or mineral deficiency, please speak with your medical provider before beginning any supplement.
It’s May, and that means it’s Women’s Health Month — an important time to focus on your own health as well as the health of the women you love.
