Learn about the qualities that make superfoods great.
"Superfood" is a non-scientific term for a natural and unprocessed food that is exceptionally rich in antioxidants and other nutrients. Common and well-known examples of superfoods include blueberries, various nuts, and dark greens like kale. Some beverages like green tea also qualify as superfoods. There are many recipes that use superfoods to give you a boost of antioxidants.
Quinoa is a small, grain-like seed and one of the few seeds or grains to contain all nine essential amino acids that the human body needs. It is also loaded with protein; a single cup contains 8 grams of protein.
Quinoa has a texture that resembles that of couscous or rice and a nutty and mild flavor. It is also easy to work with. Quinoa can be used in cereals, soups, salads and many other items. Since quinoa has a protective coating called saponin that has a bitter taste, it should be rinsed before being used. It can then be toasted in oil or boiled. When quinoa is fully cooked, it pops open, revealing the kernel's germ. The ratio of boiled quinoa is 2 cups of liquid to 1 cup of quinoa.

Chia seeds come from a desert plant called Salvia hispanica that is related to mint. They were a staple of Mayan and Aztec diets and are the seeds used in the popular Chia Pets. Chia seeds contain more fatty acids than any other known plant, and they have more antioxidants than even blueberries. They are also loaded with other nutrients like potassium, magnesium, calcium, and iron. Chia seeds are basically tasteless and can thus be used in many recipes.

Oatmeal is made from oat grains and has long been a breakfast staple. Typically served hot, oatmeal is a good food for a cold day. It is also loaded with fiber and can thus help lower cholesterol and the associated risk of heart disease. A single bowl contains 4 grams of fiber, which also helps digestion. Oatmeal also contains a lot of antioxidants, minerals, and vitamins.
There are many ways to jazz up a bowl of oatmeal. Some other superfoods, like blueberries or almonds, can make excellent toppings.
Unlike other types of tea, green tea is made by steeping the unfermented leaves of the tea plant, Camellia sinensis, in hot water. Green tea has more antioxidants than other types of tea. Green tea contains phytochemicals, including one called Epigallocatechin gallate that slows the growth of abnormal cells and thus may prevent some cancers. Two or three cups a day are recommended for the maximum health benefits.
Matcha tea is a type of green tea made from the powdered tea leaves. Since people actually drink the powdered leaves, it provides even more health benefits than ordinary green tea. Matcha is traditionally stirred with a bamboo brush until it develops froth. Matcha has a strong taste that some have compared to spinach or grass, but it can be sweetened.
Pistachios are nuts thought to have been part of the human diet since prehistoric times. They grow on trees and have a hard shell that can be cracked open. They are cholesterol-free and can help keep cholesterol levels under control. Pistachios contain a lot of protein and fiber, and they have about as much potassium as a small banana. A single serving consists of about 45 nuts that can be added to a salad. Pistachios also make a portable and healthy snack.
Almonds are the most nutritionally dense nut, which means that every ounce contains more nutrients per calorie than any other nut. A single ounce contains 191 calories and 3.4 grams of fiber, which is about 14 percent of the daily recommended amount. That same ounce also provides a lot of calcium, iron, magnesium, potassium, and vitamin E. Almonds can be eaten raw, but dry roasted nuts are easier to digest. Like pistachios, they are easy to carry and can be eaten anywhere and anytime.
Blueberries are one of the better-known superfoods. A single cup of blueberries contains 84 calories, about 24 percent of the recommended daily allowance of vitamin C, and about 14 percent of the recommended daily allowance of fiber. Blueberries also contain a lot of antioxidants that can help reduce blood pressure and may also boost metabolism. Blueberries can be eaten fresh, frozen, or dried. The freshest locally produced berries will generally be available from May to October.
Beets are root vegetables that owe their purple color to antioxidants called betalains. Beets are also good sources of fiber, potassium, vitamins A and C, and some of the vitamin B complex. They are an especially good source of vitamin B9 or folate, which helps prevent neural tube defects in developing babies. A single cup of beets contains 58 calories. Beets can be eaten raw or cooked, or they can be drunk as a juice. Powdered beets can be used to make smoothies or shakes.
Lentils are a legume, so they are in the same family as peanuts, beans, peas, and carob. They are loaded with protein, fiber, antioxidants, folate, potassium, and iron. Lentils are particularly good for vegans and vegetarians because they contain more protein than a same-sized portion of beef. Their high iron content can help prevent some types of anemia. Unlike many other foods, lentils don't lose their nutritional value after being cooked; in fact, cooking lentils makes it easier for people to absorb their nutrients. Lentils are also cheap and versatile; they can be used as a side dish or added to soup, chili, or other recipes.
Kale is a leafy green vegetable related to broccoli that boasts more antioxidants than any other fruit or vegetable. A single cup of boiled kale has only 36 calories, but it is rich in vitamin A, vitamin C, vitamin K, calcium, iron, and fiber. There are many varieties of kale, but most of them have tough leaves. Consequently, many people prefer to cook kale. It can be made into chips or powder, and the latter can be added to smoothies.
