For busy women of all ages, five foods boast high scores in essential nutrients -- iron, calcium, magnesium, vitamin K, folate, vitamin D, and omega-3 fatty acids, in particular. Best of all, these foods are easy to find at practically every grocery store, no matter where you live, and each of them takes less than 15 minutes to prepare.
1. Broccoli
Broccoli is practically unrivaled among all foods when it comes to protecting against cancer. Its powerful phytonutrients not only help neutralize carcinogens, but they also stimulate detoxifying enzymes that help the body rid itself of cancer-causing and other harmful toxins. Indole-3-carbinol, another compound found in broccoli, is particularly healthy for women; it's been shown to reduce the risk of breast and cervical cancers and helps suppress the spread of existing cancer. This green vegetable also happens to be one of the richest food sources of the flavonoid kaempferol, which has shown protective benefits against ovarian cancer.
What's more, broccoli is a superior source of folate, a B vitamin that's needed for making and protecting DNA, producing new blood, forming new cells, and synthesizing protein. Folate has also been tied to a decreased risk of some cancers in adults.
But there are a couple of reasons why this nutrient is crucial for women's health in particular. First, folate is one of the most essential nutrients for pregnant women. It supports proper development of the fetal nervous system and protects against neural tube (birth) defects. Second, research shows that women are twice as likely as men to experience depression, and numerous studies have linked folate deficiency with depression. The good news: There's also evidence showing that boosting folate levels can increase serotonin levels and improve symptoms of depression.
An added bonus: As a natural diuretic, broccoli helps reduce bloating and water retention associated with premenstrual syndrome.
Broccoli is an excellent source of dietary fiber and of vitamins C, K, and A, and it's a good source of manganese, tryptophan, potassium, B vitamins, phosphorus, magnesium, and protein. It's also high in calcium, iron, zinc, and vitamin E. Many of these nutrients work in partnership: Vitamin C helps the body absorb iron; vitamin K anchors calcium to the bone; dietary fiber promotes better absorption of all nutrients.
Quick and healthy tip: For optimal taste and nutrition, steam broccoli florets for no more than five minutes, or until they turn bright green. Drizzle with extra-virgin olive oil, lemon, and sea salt to taste.
2. Onions
Onions have many healing and health-promoting properties: They're anti-inflammatory, antibacterial, and a natural blood thinner. Rich in chromium, vitamin C, and dietary fiber, onions are also a good source of manganese, vitamin B6, tryptophan, folate, and potassium.
This bulbous vegetable is used to combat cancer, arthritis, and osteoporosis, and it helps fight infections, colds, fevers, and asthma. Onions also help prevent constipation, increase blood circulation, improve gastrointestinal health, promote heart health, and are thought to help lower blood pressure and triglycerides.
Onions are a healthy whole food, there's no doubt. But they're particularly good for women, who are four times as likely as men to develop osteoporosis -- and who are at even higher risk for osteoporosis during and after menopause. Onions help prevent bone loss by destroying osteoclasts, a type of bone cell that's responsible for the breakdown of bones. In effect, onions work like bisphosphonates, a type of medication that's commonly prescribed to treat or prevent bone disease. But unlike those potent drugs, onions bust up osteoclasts without dangerous side effects. And, like broccoli, onions are a potent cancer-fighting food; high onion consumption has been linked to a whopping 25 percent reduced risk of breast cancer and a 73 percent reduced risk of ovarian cancer.
Quick and healthy tip: Keep a container of diced raw onion in the fridge to add to meals all week -- it'll spice up a sandwich or salad, and it's an easy addition to quick stir-fries. Sautee the onion in a tablespoon of oil, then add the rest of the ingredients in roughly the order of how long they take to cook; the onion-infused oil will add a great flavor to the whole dish.
3. Leafy greens
Leafy greens, such as kale, spinach, watercress, cabbage, turnip greens, collard greens, and arugula, share similar nutrient profiles, featuring impressive scores of vitamins K, A, and C; calcium; potassium; beta-carotene; manganese; folate; magnesium; iron; and dietary fiber.
Well-known research tracking 66,940 women enrolled in the Nurses' Health Study found a 40 percent decrease in the incidence of ovarian cancer in women with the highest dietary kaempferol intake as compared to women with the lowest intake. Along with broccoli, kale is one of the best sources of kaempferol -- which has been associated with a reduced risk of heart disease. Kaemperfol is also found in tea as well as in Brussels sprouts and other greens.
Spinach is extremely high in iron, which protects the immune system and helps the body produce energy. It's especially important for menstruating and pregnant women, who require higher levels of this nutrient. However, iron deficiency is one of the most common nutrient deficiencies for all women. Iron deficiency causes anemia and low energy due to decreased oxygen being delivered to the cells. You can find iron in most leafy greens; other good sources include chard, mustard greens, and romaine lettuce.
Dark leafy greens like Swiss chard, spinach, kelp, and turnip greens are also excellent sources of magnesium, which plays a significant role in many key biological processes. This miracle mineral has been credited with a slew of health benefits, including lowering high blood pressure, strengthening the immune system, strengthening bones, aiding in sleep, relaxing muscles, and relieving stress and anxiety.
Here are a few more good reasons to gobble up magnesium-rich foods: According to womenshealth.gov, migraines plague an estimated 29.5 million Americans, and roughly 75 percent of those affected are women. Magnesium has been shown to reduce the severity and recurrence of migraine headaches. And a study of 60 women with urinary urge incontinence found that magnesium supplementation improved the symptoms of overactive bladder in nearly half of participants. Magnesium also aids in calcium absorption, playing a significant role in preventing osteoporosis; several studies on humans have shown that magnesium helps maintain bone mineral density.
Finally, according to Mental Health America, about 12 million women in the U.S. experience clinical depression each year. It's estimated that women are twice as likely as men to experience depression. Depression has been linked to low levels of calcium and magnesium, so it shouldn't come as a surprise that a study comparing the bone mass of depressed premenopausal women to their nondepressed peers found that the depressed women had reduced bone mass and the most thinning in their hip bones, putting them at higher risk of fractures.
Many leafy greens boast high levels of Vitamin E, which helps stave off menopausal hot flashes. Excellent sources of Vitamin E include mustard greens, turnip greens, and Swiss chard; you can also find it in spinach, collard greens, and kale. Like broccoli, leafy greens are natural diuretics and are great for combating bloat and water retention.
Swiss chard and spinach are two of the most calcium-dense plant foods on earth. Calcium is a particularly important nutrient for women; it's needed to build healthy bones and to prevent bone loss after menopause. Women who consume diets rich in calcium and vitamin D are less likely to develop type 2 diabetes and to experience premenstrual symptoms. Not only does calcium help build strong bones and teeth, it also plays a role in blood clotting, muscle contraction, and regulating heartbeat.
Magnesium and calcium aren't the only nutrients that contribute to bone health, though. Vitamin K is vital for bone health and plays a unique role in helping prevent osteoporosis. Just because you have sufficient calcium in your diet doesn't necessarily mean it will find its way to your bones -- and that's where vitamin K comes in. It helps calcium adhere to the bone, aiding in its absorption. In fact, without adequate vitamin K, calcium can deposit itself in joint and muscle tissue, creating painful problems and preventing absorption in the bone. Calcium deposits in soft tissue are more prevalent in women than men, so vitamin K is especially important for women. It's found in abundance in most leafy greens, particularly spinach, kale, and Swiss chard.
Quick and healthy tip: To get the most nutrition out of your leafy greens, you'll need to add a little healthy fat to help your body absorb the nutrients. Sautee dark leafy greens in coconut oil over medium heat until just wilted. Optional: Add a small handful of golden raisins while sautéing, or serve with a small handful of raw pine nuts.
4. Beans
No matter what type of bean you choose, each tiny package is bursting with a rich array of nutrients. Beans are an incredibly rich source of folate, fiber, tryptophan, protein, iron, magnesium, and potassium, and they've been linked to a reduced risk of type 2 diabetes, high blood pressure, and breast cancer.
Hands-down one of the best food sources of fiber you can find, one cup of cooked pinto beans contains nearly 15 grams of fiber (along with a score of other essential nutrients) -- but you'll find plentiful fiber in all bean varieties. Fiber is a wonder nutrient that fills you up, regulates digestion, lowers LDL ("bad") cholesterol, helps control weight, and has a preventive effect on diabetes and heart disease. Women's risk of heart disease increases significantly with menopause.
Potassium is vital to the health of every type of cell in our bodies, and you can find good amounts of this mineral in lima, pinto, and kidney beans. Potassium plays an essential part in bone strength, muscle function, and nerve function. Numerous studies have shown a positive link between dietary potassium intake and bone mineral density in pre-, peri- and postmenopausal women, suggesting an important role in preventing osteoporosis in all women. In addition, the Nurses' Health Study, which recorded data from 91,731 female participants over a 12-year period, found that women with the highest dietary potassium intake were only 65 percent as likely to develop symptomatic kidney stones as compared to their peers with the lowest dietary potassium intake.
Tryptophan is an essential amino acid with several important functions. One of them includes the ability to raise serotonin levels in the brain. For this reason, beans and other foods high in tryptophan can help regulate appetite, improve sleep patterns, and boost your mood.
Like other beans, soybeans are an excellent source of dietary fiber. And just one cup of cooked soybeans also provides a whopping 29 grams of protein. Furthermore, studies have linked the isoflavones found in soybeans with improved bone density in postmenopausal women who previously had low bone mass; researchers believe these compounds may play a significant role in preventing bone fractures. Soy isoflavones have also been credited with easing menopausal hot flashes.
Quick and healthy tip: Although dried beans are the healthiest option since they don't have added sodium, the canned variety will do just fine as long as you rinse the beans in a colander before using them. For a quick and healthy homemade hummus, combine one can of garbanzo beans; one tablespoon each of extra virgin olive oil, lemon juice and tahini; half a teaspoon of cumin; and a sprinkle of cayenne pepper in a food processor. Blend until smooth and serve with crudités. (White beans make an excellent substitute for garbanzos.
5. Wild salmon
Wild salmon is rich in omega-3 fatty acids, vitamin D, and iron, and it's a high-quality source of protein. A word of caution: Independent studies comparing the nutritional content of wild and farmed salmon showed the farmed variety had drastically reduced levels of protein and healthy omega-3 fats. Farmed salmon were also found to have significant levels of carcinogenic substances and other toxins, as well as higher levels of inflammatory omega-6 fats. If you're eating for health, opt for the wild variety.
Salmon is one of the few food sources naturally rich in vitamin D, which is needed to absorb calcium, maintain proper levels of calcium in the blood, and promote normal bone growth. Due to these qualities, vitamin D is regarded as an important nutrient in helping prevent osteoporosis. Sockeye salmon scores the highest in vitamin D; a four-ounce serving of sockeye provides 739 IU of vitamin D -- compared to Chinook salmon, which provides 411 IU for the same size serving.
Vitamin D's benefits extend beyond good bones, however. Medical and health experts now recognize this nutrient as playing an essential role in overall health. Unfortunately, vitamin D deficiency is a widespread problem that has been linked to depression and multiple sclerosis, two conditions that women are at a higher risk for than men. Researchers have additionally linked low levels of vitamin D with obesity and an increased risk of type 2 diabetes.
Our bodies don't produce essential fatty acids, so we must get them from our diet. Wild salmon is exceptionally rich in heart-healthy omega-3 essential fatty acids, which guard against inflammation, reduce the risk of strokes, lower blood lipids, boost HDL ("good") cholesterol, decrease blood pressure, and help prevent heart disease. Omega-3s might be fats, but -- in moderation -- they're actually pretty figure-friendly: Not only do they slow digestion, which means you feel satiated for longer, but they may also help get rid of belly fat. Several studies link consumption of omega-3s with reduced abdominal fat. Other benefits of omega-3s include a reduced risk of breast cancer and improved brain function. Some research suggests that omega-3s may be helpful in treating depression, although further research is needed in this area.
Quick and healthy tip: Sprinkle salmon fillets with fresh chopped rosemary and black pepper, top with lemon slices, and place under the broiler for ten minutes or until it flakes easily. Leftovers work well the next day crumbled into omelets, sandwiches, or salads.

41 Super Secrets to Trim Your Tummy
What if the fountain of youth were in your own kitchen? While we've come to expect that certain physical and mental changes are an inevitable part of getting older, the fact is that the foods we eat—or don't—may speed those processes along, aging us before our time. The reason is simple. "We eat too many processed foods," says David Katz, MD, director of Yale University's Prevention Research Center. "They're often high in calories and low in nutrients such as vitamin B12 and omega-3s, so we end up with islands of deficiencies in a sea of excess." These inadequacies can result in symptoms we tend to assume are due to aging, such as the four below. Work with your doctor to determine whether adjusting your diet or adding a supplement can help you look—and feel—younger.
The 25 most powerful health superfoods you should be eating now
If: You Have Less Energy
You May Need More: Vitamin B12
Found only in foods that are derived from animals, this nutrient helps regulate your metabolism and energy production and is key to maintaining a healthy brain and nervous system. "Fatigue is a classic sign of B12 deficiency, which usually occurs in people who don't eat very much animal protein," says Danine Fruge, MD, associate medical director of the Pritikin Longevity Center & Spa in Miami. Chewing a lot of antacids to relieve heartburn can also lead to B12 deficiency, because antacids interfere with B12 absorption.
How Your Doctor Knows: Your GP will ask about what you eat, whether you're getting enough sleep, and the medications you take. If you don't eat many (or any) meat or dairy foods or take supplements containing B12, you sleep 7 to 8 hours each night, and you're physically active, odds are good that your low energy is due to a B12 deficiency.
Food Fix: Have two servings of nonfat dairy foods, such as fat-free milk or nonfat yogurt, and 3 to 4 ounces of lean protein daily. Good sources of B12 include seafood such as fish, clams, oysters, and mussels, as well as lean beef and pork, chicken, and fortified cereal.
Supplement Solution: Take 500 to 1,000 mcg of vitamin B12 in tablet form every day to raise and maintain your B12 levels.
If: Your Joints Ache
You May Need More: Manganese and Copper
Because manganese and copper are both essential for maintaining joint cartilage and flexibility, "in most cases, supplementing these nutrients reverses the joint deterioration and eliminates the pain," says Dale Peterson, MD, director of the Comprehensive Wellness Center in Sapulpa, OK. "The body can actually repair a significant amount of damage if it's given the proper support."

How Your Doctor Knows: Using a simple blood test, your physician can easily determine whether your joint pain is related to garden-variety wear and tear or a more serious inflammatory condition. "If the result is normal, you can be assured that the joint pain isn't caused by serious rheumatic disease," says Dr. Peterson.
Food Fix: Nuts, beef, and spinach are good sources of these nutrients, but you won't be able to eat enough to get all your copper and manganese, so opt for a supplement, Dr. Peterson advises.
Supplement Solution: Take 2 mg of copper and 5 mg of manganese each day. Within 2 to 3 months, your joints should feel less painful.
To your health: The best vitamins for women
If: You're More Forgetful
You May Need More: Omega-3 Essential Fatty Acids
"These fatty acids are part of the brain's building blocks," explains Andrew Weil, MD, director of the Center for Integrative Medicine at the University of Arizona. "If you're not getting enough in your diet, the architecture of the brain becomes weak, and brain function, including memory, suffers." But it's not only the amount of omega-3s that's important; the balance between omega-3s and omega-6s is equally crucial. "Our diets are flooded with omega-6 fatty acids, mostly from processed foods," says Dr. Weil. "The more omega-6s you eat, the more omega-3s you need to balance your levels. Most of us aren't eating enough omega-3s and are eating too many omega-6s."
How Your Doctor Knows: A quick review of what you eat is all she needs. "If there's no fish, walnuts, or freshly ground flaxseed in your diet, and the fats you eat come mainly from meat, you're not getting any omega-3s," explains Manuel Villacorta, RD, an American Dietetic Association spokesperson in San Francisco.
Food Fix: First, reduce the amount of refined and processed foods you eat as much as possible, and cook with olive or canola oil. Then, eat 3 ½ounces of wild salmon and 3 ½ounces of herring, sardines, or halibut each week. Add 2 tablespoons of freshly ground flaxseed to cereal, whole grain side dishes, or shakes daily, and garnish salads or cereal with 1 tablespoon of walnuts 5 days a week. Finally, enjoy 9 to 12 almonds 4 times a week.
Supplement Solution: Take at least 2,000 mg of fish oil daily. Look for 1,000 mg capsules of combined docosahexaenoic acid (DHA) and eicosaentaenoic acid (EPA).
Sharpen your mind, fight Alzheimer's, and protect your heart against disease with this nutrient
If: Your Blood Pressure Is Rising
You May Need More: Potassium
"Having too little potassium in your diet magnifies the toxic effects of excessive salt intake," Dr. Fruge says. Most processed foods have added sodium but no extra potassium, so if your meals come from boxes, you're likely at risk. Worsening the situation, when your kidneys try to flush out the salt, you lose even more potassium. "The imbalance damages blood vessels, driving up blood pressure," Dr. Fruge notes. "Eating better can correct the problem—I've seen people drop thirty points in three days."
How Your Doctor Knows: A review of your diet reveals all your GP needs to know. If there's any doubt, he can evaluate your cardiovascular function with blood tests to check blood sugar, cholesterol levels, and kidney function, along with stress tests, body-fat measurements, and ultrasounds of your heart and arteries.
Food Fix: Cut your sodium consumption to no more than 1,500 mg per day, and eat seven to nine servings of fruits and vegetables every day.
Supplement Solution: Potassium supplements can lead to arrhythmia or other cardiac problems, says Danine Fruge, MD. Stick with produce to avoid those side effects.
