9 Superfoods to Protect and Prolong Health

* ALMONDS are high in vitamin E. They’re good sources of B vitamins, fiber, copper, iron, magnesium, potassium, riboflavin, and zinc. These nuts also contain healthy fats. Besides a reduced risk of coronary heart disease, diabetes, and certain cancers, almonds have potential prebiotic effects: They may stimulate growth of good bacteria in the intestinal tract. Eaten in moderation (about 22 nuts) almonds can help you manage weight; they provide satiety and may also increase excretion of fat from the body.

* BERRIES have a profound, positive impact on health and performance. All kinds of these flavonoid-rich gems are being studied for their antioxidant benefits. In addition to protecting against cancer, stroke, and heart disease, blueberries, cranberries, and strawberries have phytochemicals that appear to protect against age-related declines in cognitive functioning and may even help reverse them by counteracting oxidative stress and decreasing inflammation. In addition to disease-fighting substances, blackberries and blueberries offer vitamins C and K (which may help prevent osteoporosis). When berries are not in season, frozen varieties work well in smoothies.

* CABBAGES (bok choy, broccoli, Brussels sprouts, cauliflower, kale, and watercress) all offer an expansive array of nutrients and antioxidants. Most of us would do well to triple our intake of this family of veggies. The American Cancer Society recommends eating cabbage and its relatives to reduce the risk of cancer. These foods contain sulforaphane, an organic chemical compound shown to inhibit the growth of carcinogen-induced cancers as well as H. pylori bacteria, a cause of gastric infection.

* FISH (Alaskan halibut, bass, light tuna, herring, mackerel, sardines, and trout) are all part of a healthy diet. The American Heart Association recommends at least two servings of fatty fish a week to protect circulatory health, support cognitive functioning, and reduce inflammation implicated in arthritis, asthma, cardiovascular disease, and stroke.

* GREEN TEA has mild thermogenic properties that boost metabolism to burn calories. Research suggests it may also inhibit storage of new fat. Green tea’s main active ingredients are polyphenols that protect the body from free radicals and help prevent oxidative damage. In particular, ECGC has been found to lower cholesterol and may inhibit cancer cell growth. This polyphenol also helps regulate insulin, which plays an important role in weight regulation.

* LEAFY GREENS (arugula, endive, escarole, sorrel, spinach, and more) are super sources of many vitamins, minerals, and phytonutrients. Their combination of nutrients, phytochemicals, and soluble fiber make these powerful anticancer foods, according to research. One serving a day can lower your risk of coronary vascular disease, improve blood glucose metabolism, maintain healthy bowel function, and protect bone density.

* LEGUMES—all kinds of beans, fermented soy, lentils, and peas—are low in fat and calories but rich in protein, fiber, folate, iron, magnesium, potassium, selenium, and zinc. Legumes have more disease-fighting antioxidants than almost all other plants. Consumption has been linked to reduced risk for heart disease and diabetes in mildly insulin-resistant adults while lowering colon cancer incidence. An excellent source of complex carbohydrates and plant-based protein, legumes are high in fiber so you eat less. They’re the only food to earn the USDA’s inclusion in two food groups: meat and vegetable.

* WHOLE GRAINS (brown rice, bulgur, buckwheat, kamut, oats, quinoa, teff, and more) may protect against chronic disease, including cardiovascular disease, diabetes, obesity, and various cancers. These unrefined grains have hundreds of phytochemicals including lignans, plant stanols and sterols, phytoestrogens, and saponins that protect cells from damage linked to cancer. Thanks to their fiber, whole grains also help you maintain a healthy weight. Eat at least three servings daily for energy and long-term health.

* YOGURT AND KEFIR have all of milk’s nutrition, plus billions of probiotics—healthy bacteria that fight lactose intolerance, constipation, diarrhea, and infections while enhancing immunity. The benefits of these probiotic foods are linked to their live active cultures, which can reduce the risk of allergies, irritable bowel syndrome, hypertension, elevated cholesterol, certain cancers, and some infections. Yogurt and kefir are also excellent sources of dietary calcium, which may play a role in weight control, as well as muscle and bone health.

All About Black Beans

As more and more people begin to discover how uniquely delicious and nutritious black beans are, their popularity has begun to soar.

Black bean nutrition - focus on protein and fiber

When it comes to three basic categories of nourishment-protein, fiber and antioxidant related substances- black beans have an especially solid nutritional profile. Black beans, like other beans, really pack a punch when it comes to protein and fiber. On average, each cup features about 15 grams of both protein and fiber.

Black bean nutrition - focus on flavonoid anti-oxidants

While all beans are exceptionally healthy foods when it comes to their protein and fiber content, it's the color coat on black beans that makes them particularly interesting. Researchers have found at least 8 different flavonoids in the black bean's color coat. Flavonoids are typically color-producing phytonutrients pigments that have great antioxidant potential. They can also be responsible for some of the unique flavors found in foods. Flavonoids work together with vitamins to help the body avoid oxygen-related damage.

Many other foods have been studied for their flavonoid content, and foods like red grapes or red wines are famous for their rich supplies of one flavonoid family, called anthocyanins. As it turns out black beans are an equally rich source of this flavonoid family, containing about 2.37 grams of anthocyanins per 100 grams of seed coat.

Black bean nutrition - focus on omega 3 fatty acids

Black beans also contain small amounts (about 180 mg per cup) of omega-3 fatty acids. This amount is about three times the amount available from many other beans, including kidney beans. While the amount of omega-3 fats in one cup of black beans is roughly equal to the amount in one ounce of a cold water fish like halibut, it can still be a valuable addition to your Healthiest Way of Eating since omega-3 fats are essential to protecting your health.

Black bean nutrition - focus on vitamins and minerals

In addition to the nutrients already discussed, black beans also feature concentrated amounts of other important vitamins and minerals. Based upon our nutrient rating system, black beans are an excellent source of one nutrient (molybdenum), a very good source of three nutrients (folate, fiber, and tryptophan) and a good source of five nutrients (manganese, protein, magnesium, vitamin B1, and phosphorus).
