Rolled oats, often referred to as old-fashioned oats, are made from whole oat groats that have been steamed and then rolled into flat flakes. This process helps to preserve the oats' natural flavor and extend their shelf life, typically lasting around 6-9 months after opening. Rolled oats are known for their chewy texture and are a staple in many households, often used in oatmeal, granola, and baked goods.

Rolled oats are nutrient-dense, providing a good source of fiber, protein, vitamins, and minerals. They have a moderate glycemic index (GI) of around 53, which means they release energy slowly and can help maintain stable blood sugar levels. This makes them a great choice for a satisfying breakfast.

Quick cooking oats are similar to rolled oats but are processed further. They undergo a longer steaming process and are rolled thinner, then cut into smaller pieces. This additional processing allows them to cook much faster, typically in about 1-5 minutes.

Nutritionally, quick cooking oats are comparable to rolled oats, providing similar amounts of fiber, protein, and essential nutrients. However, they have a higher glycemic index, usually around 71, which means they can cause a quicker spike in blood sugar levels compared to rolled oats. This is due to their smaller size and greater surface area, which allows them to absorb liquid more rapidly.
