Mainly grown in North America and Europe, oats (Avena sativa) have gained considerable interest as a health food due to their high dietary fiber content.[1,2]
Oats are the only dietary source of powerful antioxidants called avenathramides, which help regulate blood pressure and reduce arterial inflammation.[3,4,5] Studies show that oats can lower cholesterol levels that in turn decrease the risk of heart disease.[6,7]
The majority of the fiber in oats is soluble. Beta-glucans, that forms a majority of the insoluble fiber in oats, forms a viscous (gel-like texture) solution and help lower cholesterol levels and increase the excretion of bile acids.
The high content of soluble fibers in oats as compared to other grains, slows digestion, increases satiety and suppresses appetite.[8,9]
Oats For Type 2 Diabetes
Type 2 diabetes involves loss of control over blood sugar levels resulting from decreased sensitivity to the hormone insulin.
Studies show that beta-glucans in oats can help reduce blood sugar levels and regulate glucose and insulin responses after carbohydrate-rich meals. [10,11, 12,13,14] A clinical study done in patients with type 2 diabetes and severe insulin resistance found that when oats were included in the diet for four weeks, it resulted in a 40 percent decrease in the dosage of insulin needed for stabilizing blood sugar levels.
A few other studies suggest that beta-glucans in oats may favorably alter insulin sensitivity and delay or prevent the onset of type 2 diabetes.[16,17,18,19]
How To Take It
- In a large saucepan, bring four cups of water to a boil. Add ¼ teaspoon salt and one cup of steel-cut oats. Cover and simmer for 25 minutes minutes or until the oats are just tender and the liquid is almost absorbed. Eat this twice daily to have better control over blood sugar levels.
- Here are some other healthy oat recipes you can try.
