Why does oatmeal cause gas?

Oatmeal is a cereal rich in fiber, according to the Spanish Nutrition Foundation, a 100-gram portion of oatmeal can have approximately 5.6 fiber, more than white rice, white wheat flour or wheat semolina.

Although it is a good component for the body, it is worth clarifying that this cereal contains both soluble and insoluble fiber, and the latter, when fermented, can cause gas or other discomforts such as inflammation.

As the blog explains Lekué, during digestion, the bacteria in the intestine are responsible for breaking down food that was not properly digested, as is the case with fiber. In this process, small amounts of gas may be produced as a result of fiber fermentation.

How to consume it?

There is no doubt that oatmeal is one of the healthiest products that can be included in the diet. According to the Spanish Nutrition Foundation, this cereal is a rich source of nutrients such as calcium, magnesium, potassium, phosphorus, as well as Vitamin B, Vitamin B6 and Vitamin E.

Likewise, due to its fiber and protein content, it is characterized as a food that produces a feeling of satiety, which makes it ideal as an alternative to other foods or to calm hunger between meals.

Nevertheless, To avoid digestive discomfort, the intake of this cereal should be regular, balanced and should only be an additional ingredient in a balanced diet.

Some tips to consume it correctly and avoid excess gas are:

  • Add a greater amount of fiber to the diet, on a regular basis, little by little. In this way, the digestive system gets used to the intake of fiber and prepares to process it.
  • Soaking the oatmeal before consuming it facilitates its digestion and does not detract from its nutritional properties.
  • Using the oats in different preparations or trying other presentations can be an option. However, it is questioned whether it retains its properties after being combined with other ingredients.
  • Cook the oatmeal, thus facilitating its digestion.
