The US Food and Drug Administration recommends that people living with a high risk of coronary heart disease consume beta-glucan soluble fibre from whole grain oats.

"The oat industries and consumers may benefit from greater knowledge and understanding of clinical effects, range of occurrence, distribution, therapeutic doses and food functional attributes of other oat bioactives such as avenanthramides and saponins as well as other anti-inflammatory agents found in the cereal," the National Institute of Health (NIH) states.

What Are Steel-Cut Oats?

This type of oats is rough, chewy in texture and possesses a nuttier flavour when compared to rolled oats. Steel-cut oats take longer to prepare ranging from 15-30 minutes.

What Are Rolled Oats?

This type of oats is also known as old-fashioned oats that have a milder flavour and softer texture when compared to steel-cut oats. It takes much less time to prepare as they have been partially cooked.

According to studies, steel-cut oats have a lower GI (a measuring factor to determine how carbs affect your blood sugar levels) than rolled oats because their shape makes them take longer to digest. These findings suggest that your body absorbs carbohydrates more slowly, resulting in more stable blood sugar levels. Additionally, traditional oats have slightly higher GI than steel-cut oats, which can accelerate starch gelatinization resulting in quicker glucose release.

Which Is Better To Lower Cholesterol Levels?

When it comes to their nutritional value, both steel-cut and rolled oats have similar nutrition that can support better health. Consuming any type of oats can have a significant impact on your diabetes management, lower risk of cancer, decreased inflammation, improved gut health and better weight management, but when it comes to supporting your heart health, there's some evidence that steel-cut oats may be healthier.

"Beta-glucan is an important component of dietary fiber found in oat grains. It is the major active compound in oats with proven cholesterol-lowering and antidiabetic effects. Oats also provide substantial levels of other bioactive compounds such as phenolic acids, tocols, sterols, avenacosides, and avenanthramides," NIH explains. "The consumption of oats has been determined to be beneficial for human health by promoting immunomodulation and improving gut microbiota."
