Health Benefits of Oats

The oat Avena L.) is a wheat cereal same family. She is from Asia and comes from wild red oats. Cultivated over 2,000 years ago, it has become extremely popular in Europe, particularly in Scotland, Germany, Great Britain and Scandinavian countries. The Scots liked the cereal so much that they took it to the United States in the 19th century when they emigrated.

The biggest producers are the United States, Germany, Poland, Finland and Russia. In Brazil, Paraná is one of the biggest producers. Rio Grande do Sul also stands out as a great producer. The large number of crops is because oats are very resistant to cold.

But Brazil imported the cereal until 1970, when varieties were created. Brazilian production surpassed that of Argentina and the country gained the status of the largest Latin American producer. In the 1990s, there was a decline, but with the inclusion of oats in the category of functional food by the National Health Surveillance Agency (Anvisa) production gained new impetus.

In 2016, the harvest was 110.6% higher compared to 2015, a factor also explained by the rains. Another interesting fact about the cultivation of the grain in Brazil is the fact that it is also aimed at animal consumption.


Cereal varieties are classified according to their extraction. We will present 4 types, 3 of which are healthier and the last one requires moderation in consumption. Know the characteristics of each one:

  1. Oats in flakes: healthier because the grains are pressed whole, which keeps the high fiber content. Oat flakes are thin or thick and can be served with fruit, yogurt, smoothies and milk, in addition to cake and biscuit recipes;
  2. Oat bran: also has a lot of fiber, as it is obtained from the husk. This variety can be consumed in the same way as the previous one. Because it’s thinner, it’s also great for making pancakes;
  3. Oatmeal: has less fiber compared to the others, as it is obtained from the inside of the cereal. Use this flour as a substitute for wheat flour;
  4. Flavored oats: Instant porridges have preservatives and flavored oats can lose their nutritional power, even when combined with healthy ingredients like apples and honey. Avoid ready-to-eat porridges and consume flavored oats moderately.


As we’ve already talked about, it is a functional food. That means being able to help prevent and control disease. Fibers are the main nutrients of oats, however, iron, proteins, calcium, magnesium, manganese, copper, zinc, selenium and vitamins of the B complex also justify its reputation as a super cereal. Are you one of those people who find cereal something boring? So, read carefully the list of benefits of oats!
