It is known that the cultivation of cereals is about 10,000 years ago and references to this food are very old as they appear in texts of historians, as when Pliny, a Roman historian of first century AD, referred to the strength of Germanic and said they ate preparations made with oatmeal.

Taking oats daily reduces cholesterol

The real dietary revolution began in the 1970s, when several studies focused on whether the diet rich in fibers in African countries was responsible for the absence of diseases as common in the West as varicose veins, constipation, cholesterol or colon cancer.

These studies produced a boom in consumption of oat bran, when Dr. Anderson, of the Kentucky School of Medicine, showed that fiber reduced the levels of bad cholesterol (LDL) and triglycerides and increased the good cholesterol (HDL).

Dr. Anderson verified these effects satisfactorily in his own person: With the habitual consumption of oats, he saw how after a few weeks of consuming this cereal with abundance, his cholesterol dropped from 285 to 175.

Oats, advantages of the soluble and insoluble fiber

Oats is the only cereal that provides soluble and insoluble fibers. Most cereals contain only insoluble fiber. Oatmeal also contains soluble fiber, called beta-glucans.

On the one hand, the insoluble fiber it contains facilitates and accelerates intestinal transit and prevents constipation.

While it passes through the intestinal tract, the oat fibers capture bile, cholesterol and residues, which are subsequently excreted, helping to purify and clean the digestive system.

Oats for heart health

The soluble fiber of oats, beta-glucans, reduces cholesterol by hindering intestinal absorption. Scientific studies have confirmed these properties of beta-glucans: It has been shown that the daily intake of 3 grams of beta-glucans (about 3 servings of oats) reduces cholesterol levels.

It is especially recommended for people with heart problems, hypertension or poor circulation to help reduce the risk of cardiovascular accidents associated with excessive cholesterol.

It is necessary not to forget that, besides soluble fiber, its content in omega-6 fatty acids, also help reduce blood cholesterol.

It contains many amino acids such as leucine, isoleucine and threonine, necessary for infant growth with methionine which also helps to remove cholesterol by making the liver produce more lecithin, and allows the body to remove heavy materials.

Oats have a prebiotic effect by stimulating the growth of healthy bacteria in the intestine. It is very beneficial for people with hemorrhoids to increase the volume of stools and facilitate their expulsion.

These properties are increased when combining oats with yogurt or foods with probiotics, that is, foods containing healthy bacteria to "seed" a healthy intestinal microbiota, which will protect the digestive membranes and stimulate the properties of the intestinal flora, including that of increasing immunity.

But the advantages of fiber do not end here. This type of fiber has the property of absorbing particles that are not very convenient for the organism, as contaminants that can cause cancer in the intestines, and estrogens, which seem to have a determining influence on the appearance of breast cancer or premenstrual syndrome. .

Benefits of oats for digestive diseases

This same fiber is a good resource for pampering the digestive mucous membranes. The carbohydrates provide their demulcent properties, exerting a softening and protective role of the intestinal walls.

It is very helpful to treat diseases of the digestive system, such as heartburn, stomach pain, gastritis, digestive ulcers or multiple problems of the intestines, such as irritable bowel syndrome, or especially those people prone to colic.
