Rolled Oats vs Porridge Oats

Regardless of the season, oats are almost always found on the breakfast table. Oats are sought after for their unique taste and texture, coupled with the nutrition and satisfying warmth they provide.

Besides being a breakfast staple, oats have a variety of different uses. For instance, you’ll find them in nutritious granola bars, pancakes, and even muffins.

Due to their wide range of uses, there are many different types of oats for each purpose, just like there are many types of honey. You might’ve noticed some oats are creamier than others, while some are chunkier.

Initially, every type of oat starts out as oat groats, which are then roasted and processed differently to create new types of oats. Here’s everything you need to know about oats, from what they are to how they’re used.

What Are Porridge Oats?


When it comes to breakfast, porridge is one of the most popular dishes out there. It’s a cereal dish made out of boiled or chopped grains, typically submerged in milk. But do you know what are porridge oats?

There are many different types of grains used in the making of porridge to create unique textures and tastes. Porridge oats are one of many types of grains that are used to create a porridge.

However, there’s a widespread misconception that porridge oat is basically a term for any oat grain that’s used to make porridge.

In reality, that’s not true, as porridge oats are a unique type of grain, with a special texture and taste, used to make porridge or similar foods. Porridge oats are also often known as Scottish or Irish oats.

What really distinguishes porridge oats from other types of oats is the manufacturing process. Unlike other types, porridge oats are ground and chopped up.

Consequently, the final product is more powdery, leading to a creamier dish. Irish porridge oats are cut using a steel blade, creating a uniformly cut mixture of oats.

In contrast, Scottish porridge oats are cut using stone, leading to ground oat flour mixed with irregularly cut oats.

What Are Rolled Oats?

On the other hand, rolled oats are another type of oat grain used in food dishes such as porridge. Rolled oats are also known as old fashioned oats by many people.

Just like porridge oats, they are oat groats. However, they are a whole grain form of oats, unlike the chopped-up version known as porridge oats.

But as the name suggests, rolled oats are steamed and flattened using a heavy roller, separating them from the pure whole grain form.

The manufacturing process of rolled oats introduces changes in size, shape, cooking time, and texture.

They are steamed thoroughly before packaging, while the flattening increases their surface area, which allows for easier cooking.

Quick oats are a type of rolled oats that are highly pressed and flattened to make cooking even faster.

Health benefits of oats

Whether it’s rolled oats or porridge oats, eating them can be incredibly nutritious for your body in numerous ways. It’s safe to say that a well-balanced diet is incomplete without this essential item.

Out of all their health benefits, oats are known for being fibre rich and containing the Beta-Glucan, which is a soluble fibre.

Oats contain great amounts of this special fibre, which helps our body reduce cholesterol and blood sugar while encouraging the growth of healthy gut bacteria. This fibre is also responsible for the prolonged feeling of fullness after eating oats.

However, fibres aren’t the only nutritious thing inside oats. They are also known to be rich in antioxidants, which help reduce the risk of many diseases and damage from oxidants.

Most importantly, oats are the best source of an antioxidant called avenanthramide, as it’s very rarely found in our diets. Together with other antioxidants, avenanthramides reduce blood pressure and lead to better blood flow by dilating blood vessels.

Moreover, these antioxidants also have anti-itching and anti-inflammatory properties.

Among numerous other health benefits, eating oats can also help you control your blood sugar levels more effectively.

This is especially useful for people with type 2 diabetes or obesity. Moreover, oats can keep you full for a long time, which can be useful for people trying to lose weight.
