Why are oats so effective? The key lies in their beta-glucans, special soluble fibers that act as a natural filter in the body. When consumed, they turn into a gel-like substance in the intestine, which blocks the absorption of cholesterol and slows the rise of blood sugar after a meal.
Oats and cholesterol: a natural solution for a healthy heart
Cholesterol is a fatty substance in the blood that the body needs, but too much so-called bad cholesterol (LDL) can increase the risk of heart and vascular diseases. Oats work by binding excess cholesterol in the digestive system and removing it from the body before it is absorbed into the bloodstream.
A study published in the American Journal of Clinical Nutrition showed that consuming 3 grams of beta-glucans per day can reduce LDL cholesterol levels by 5 to 10%. This means that even one cup of cooked oatmeal a day may contribute to a healthier heart.
According to the World Health Organization (WHO), elevated cholesterol is responsible for about 2.6 million deaths annually. While there are various medications to regulate cholesterol, dietary changes such as including oats can significantly reduce the need for them.
Oats and blood sugar: natural support for diabetes
For those who face diabetes or blood sugar swings, oats are one of the best foods. Beta-glucans slow down digestion and the absorption of carbohydrates, which means blood sugar rises more slowly and steadily.
In a study published in the journal Diabetes Care, researchers found that oat consumption in patients with type 2 diabetes lowered post-meal blood sugar levels by 10 to 20%. Additionally, regular consumption of oatmeal led to improved insulin sensitivity.
For comparison: an average person, after eating a meal with simple carbohydrates such as white bread or sugar, experiences a blood sugar spike of 40 to 50%, while a meal rich in fiber, such as oatmeal, causes only a 15 to 20% increase.
How much oats should you eat for optimal results?
According to research, the recommended daily amounts of oats are as follows:
- To lower cholesterol: 3 to 5 grams of beta-glucans per day (which equals about 50 to 100 g of oatmeal).
- For blood sugar stabilization: 1 to 2 servings of oats daily (about 30 to 60 g of oatmeal).
For best results, it is recommended to consume whole grain oatmeal or oat bran, as instant varieties often contain added sugars and less fiber.
Additional benefits of oats
Oats are not only helpful in managing cholesterol and blood sugar, but they offer many other benefits:
- They contain antioxidants, such as avenanthramides, which reduce inflammation and protect blood vessels.
- They promote digestion and help with issues such as constipation and irritable bowel syndrome.
- They provide long-lasting energy due to complex carbohydrates and fiber.
