Steel-cut oats are processed differently than rolled oats. They are cut into thin slices by sharp, steel blades, which allows them to preserve more protein and fiber. The "Archives of Internal Medicine" published a study in 2003 that found that soluble dietary fiber leads to a decreased chance of developing heart disease. Steel-cut oats contain an abundant amount of soluble dietary fiber and have been linked to a decrease in coronary heart disease. This fiber also helps control cholesterol levels and blood pressure.
Steel-cut oats also have a low glycemic index, which is ideal for diabetics or those who need to control blood-sugar levels. They lower blood-glucose and insulin levels after eating or fasting. Those struggling with weight loss may also benefit from steel-cut oats. The oats make a person feel full for a longer period of time and prevent rapid fluctuations in blood-glucose levels.
Athletes and anyone in need of more protein and iron may also benefit from steel-cut oats. They are a good source of B vitamins and are low in tryptophan, leading to an increase in energy.Learn more about Nutrition & Diets
