You have must heard some people including superfoods in their daily diet. Here are the benefits of superfoods.
The higher levels of flavonoids in berries have been shown to lower the risk of a heart attack. A few commonly identified superfood berries include acai berries, blueberries, raspberries, tart cherries, cranberries, and goji berries.
They boast the following benefits:
Acai berries: These are small, dark purple berries grown in South America. They contain 19 amino acids and many antioxidants.
Blueberries: These are high in fiber, manganese, and vitamin K. Cranberries are high in a particular flavonoid that helps lower the risk of urinary tract infection.
Goji berries: These are a small red berry native to Asia that are high in vitamin C and E, along with many different types of flavonoids. They are frequently used in Eastern medicine to help treat diabetes and high blood pressure and maintain eye, liver, and kidney health.
Soybeans have a high concentration of isoflavones, a type of phytochemical. Phytochemicals are compounds that occur naturally in plants. Some research demonstrates that isoflavones in soy help reduce the amount of low-density lipoprotein (LDL) or “bad” cholesterol in the blood. A few studies have shown that soy may prevent age-related memory loss. Soy isoflavones might also reduce bone loss and increase bone mineral density during menopause, as well as decreasing menopausal symptoms.
Share onMany foods considered to be “superfoods” are rich in color, often indicating that they are rich in antioxidants. Tea contains few calories, helps with hydration, and is a good source of antioxidants. Catechins, potent antioxidants found primarily in green tea, have beneficial anti-inflammatory and anti-carcinogenic properties. Green tea may also have an anti-arthritic effect by suppressing overall inflammation.
People often identify kale, spinach, Swiss chard, beet greens, and collard greens as superfood leafy greens. These foods are rich in vitamins A, C, E, and K, and many B vitamins. Leafy greens also contain an abundance of carotenoids, iron, magnesium, potassium, and calcium. One cup of kale provides 550 micrograms (mcg) of vitamin K, equivalent to over 680 percent of a person’s daily needs. Kale and other leafy greens are high in fiber and water content, both of which help to prevent constipation and promote regularity and a healthy digestive tract.
The high omega-3 fatty acid content in salmon and other fatty fish, such as trout and herring, can decrease the risk of abnormal heartbeats, reduce cholesterol and slow the growth of arterial plaque.
Research has found that dark chocolate is high in flavonoids. Flavonoids demonstrate antioxidant activity, prevent coronary heart disease and certain types of cancer, and boost the immune system. The component in chocolate specifically responsible for these benefits is cacao powder. Manufacturers derive this from cacao beans. Bear in mind that chocolate may have added ingredients, such as added sugar, that might negate these benefits.
Wine and grapes
Share onGrapes, particularly red grapes, contain healthful components such as resveratrol and quercetin.
Resveratrol, the polyphenol found in wine that made it famously “heart healthy”, is present in the skins of red grapes. A few studies have shown promise that resveratrol can protect against diabetic neuropathy and retinopathy. These are conditions caused by poorly controlled diabetes where vision is severely affected. One 2013 study found that it reduced the effects of neural changes and damage associated with diabetic neuropathy. Researchers have also found resveratrol to be beneficial for treating Alzheimer’s disease, relieving hot flashes and mood swings associated with menopause, and improving blood glucose control. However, large studies using human subjects are still needed to confirm these findings. Another flavonoid that occurs in grapes, quercetin, is a natural anti-inflammatory that appears to reduce the risk of atherosclerosis and protect against the damage caused by LDL cholesterol in animal studies. Quercetin may also have effects that act against cancer.
