Health benefits of quinoa

Quinoa (pronounced keen-wah) and other ancient grains, such as amaranth, barley, and farro are rapidly growing in popularity because of their wide array of health benefits.

Ancient grains are referred to as such because they have remained largely unchanged for hundreds or even thousands of years. Quinoa was known to the Incas as “the mother of all grains” and was first cultivated over 5,000 years ago.

There are hundreds of cultivated types of quinoa, but the most common versions available in stores are white, red, and black quinoa.

This article will look at the nutritional content of quinoa, its health benefits, and how to add it to the diet.

Key points about quinoa

  • Quinoa is thought to help prevent a number of diseases.
  • It is relatively high in antioxidants, compared with other grains and cereals.
  • It can be prepared in as a little as 15 minutes.
  • Quinoa has a naturally bitter coating called saponin that acts as an insecticide.

Nutritional Facts about Quinoa

Botanically, quinoa is not classified as a grain. It is a pseudo-cereal. This means it is a non-grassy plant used in much the same way as cereals and grains with a similar nutritional profile.

The seeds of pseudo-cereals can be milled and ground into flour just as other grains and cereals.

However, nutritionally, quinoa is considered a whole grain. Whole grains include the entire intact grain seed without removing any of its parts.

In contrast, when grains are milled or refined like white bread, white rice, and white pasta, they have been processed to create a finer, lighter texture. This process removes most of the fiber and important nutrients.

Whole grains, such as quinoa, provide essential vitamins, minerals, and fiber. These help regulate the digestive system and keep you fuller and more satisfied.

In contrast, pasta, white rice, and white bread provide simple carbohydrates that are quickly digested but little else in the way of nutritional value.

Quinoa is naturally gluten-free. One cup of cooked quinoa, weighing 185 grams (g), contains:

  • 222 calories
  • 8.14 g of protein
  • 5.2 g of fiber
  • 3.55 g of fat, of which 0.42 g is saturated
  • 39.4 g of carbohydrate
  • Magnesium – 30 percent recommended daily allowance (RDA)
  • Manganese – 30 percent RDA
  • Folate – 19 percent RDA
  • Phosphorous – 28 percent RDA
  • Copper – 18 percent RDA
  • Iron – 15 percent RDA
  • Zinc – 13 percent RDA
  • Potassium – 9 percent RDA

One cup also contains more than 10 percent of the RDA of the vitamins B-1, B-2, and B-6, and traces of vitamin E, B3, and calcium.

Additionally, quinoa contains a healthy dose of fatty acids:

“About 25 percent of quinoa’s fatty acids come in the form of oleic acid, a heart-healthy monounsaturated fat, and about 8 percent comes in the form of alpha-linolenic acid (ALA), the omega-3 fatty acid most commonly found in plants.”

    Quinoa has a high protein-to-carbohydrate ratio when compared with other grain products. It was proposed by NASA to be an ideal food for long duration space flights.

    10 health benefits

    Below are some of the health benefits of regularly consuming quinoa:

    1) It is a complete protein

    It is one of only a few plant foods that are considered a complete protein, containing all nine essential amino acids – these are the amino acids that our bodies cannot produce and, therefore, need to consume.

    This makes quinoa a great dietary choice for vegetarians and vegans.

    2) High fiber

    The high fiber content of quinoa may help to improve blood sugar control.

    Because of Quinoa’s high fiber content compared with other grains, it helps reduce the risk of a number of health conditions.

    These conditions include constipation, heart disease (by lowering blood pressure and reducing cholesterol), and hemorrhoids.

    High-fiber diets have been shown to help improve blood sugar control. This can be beneficial for individuals with diabetes or prediabetes.

    Also, diets rich in fiber tend to promote a healthy weight because fiber helps you feel fuller for longer, potentially reducing the overall intake of food.

    3) Quinoa antioxidants

    Quinoa provides a higher amount of antioxidants than other common grains used in a gluten-free diet. Most gluten-free products consist of corn, rice, or potato flour and lack the nutrients that products incorporating quinoa can provide.

    Researchers at Columbia University’s Celiac Disease Center found that the nutritional content of gluten-free diets was significantly improved by adding oats or quinoa to meals and snacks.

    There are new studies emerging on a regular basis confirming the health benefits of adequate whole grain intake and their antioxidant capacity.

    4) Quinoa and manganese

    One cup of cooked quinoa contains almost one-third of the recommended daily allowance of manganese. Manganese is essential for development, metabolism, and the antioxidant system. This element is also vital for the proper functioning of many enzymes.

    5) Quinoa iron content

    Iron is necessary for a range of processes in the human body. For instance, it is an essential component of hemoglobin, the compound that carries oxygen in our blood. Maintaining adequate levels of iron is essential for health.

    6) Lysine

    Lysine is important for the synthesis of proteins. Although deficiency is rare, it can cause a range of medical issues because it is so widely used in the body. Quinoa contains more lysine than any other grain.

    7) B-2 in quinoa

    One cup contains around 10 percent of the recommended daily allowance of vitamin B-2 (riboflavin). B-2 is essential for the proper functioning of a range of enzymes.

    There is some evidence that riboflavin might help reduce some types of migraine headache.

    Although rare in Western countries, B-2 deficiency can cause oily skin rashes, anemia, and itchy, red, sensitive eyes.

    8) Magnesium

    One cup of cooked quinoa contains almost one-third of the recommended daily allowance of magnesium. Magnesium is essential for the function of more than 300 enzymes; it is present in every cell of the body.

    Low levels of magnesium are associated with muscle spasms, cardiovascular disease, diabetes, high blood pressure, osteoporosis, and migraines.

    9) Quinoa contains quercetin and kaempferol

    Quercetin and kaempferol are flavonoids that are found in relatively high levels in quinoa. These antioxidants are thought to protect against a range of chronic diseases, including cancer.

    10) Prevents kidney stones

    Quinoa has a potential protective effect against kidney stones. This is because quinoa helps manage potassium levels.

    Quinoa in the diet

    Although most packaged quinoas have the saponin already removed, it is never a bad idea to give it an extra rinse.

    It is easy to incorporate quinoa into your diet – just use it in place of rice in any recipe. Its small grains cook to tender in as little as 15 minutes.

    Quinoa has a subtle nutty taste that makes it a versatile ingredient in the kitchen. It can be used in baking or as a breakfast grain; it also works well in hot side dishes, cold salads, and even in burgers.
