The Processing of Commercial Oats
To understand whether oats are considered raw food, one must first look at their journey from the field to the store shelf. The whole oat grain, known as a groat, has its indigestible hull removed. After this, to prevent rancidity caused by naturally occurring enzymes, the groats are heat-treated or 'kilned'. This steaming and heating process deactivates the enzymes that would otherwise cause the fats in the oat to break down and go sour. This crucial step is why no commercially sold oats are truly raw in the most literal sense of the word, which defines raw as never having been heated above a specific, low temperature.
Uncooked vs. Raw: The Key Distinction
For most consumers, the term 'raw oats' is synonymous with 'uncooked oats.' These are heat-stabilized oats that do not require boiling before consumption. Common examples include rolled oats used in overnight oats or quick oats blended into smoothies. The distinction is important, particularly for those following a strict raw food diet, where all food must be unprocessed and unheated beyond a certain temperature. While soaking allows these oats to be prepared without further cooking, their initial processing means they fall outside the strict raw food category.
The Benefits and Considerations of Uncooked Oats
Eating oats in their uncooked (soaked) form can offer several nutritional benefits, though it also comes with certain considerations. Soaking helps break down phytic acid, an anti-nutrient that can inhibit the absorption of minerals like iron and zinc. This practice also improves digestibility and texture, preventing the digestive discomfort sometimes caused by eating dry oats. Furthermore, soaked oats retain higher levels of resistant starch, which acts as a prebiotic and is beneficial for gut health.
Best practices for preparing uncooked oats:
- Use a one-to-one ratio of oats to liquid (water, milk, or a non-dairy alternative).
- Add a splash of lemon juice or another acidic medium to aid in breaking down phytic acid.
- Refrigerate the mixture for at least 6-12 hours to allow the oats to absorb the liquid and soften.
- Stir in fruits, nuts, and seeds for added flavor and nutrients.
The Health Benefits of Cooking Oats
While uncooked oats offer unique advantages, cooking also makes certain nutrients more accessible and is easier on the digestive system for some individuals. Cooked oats are a creamy, warm breakfast and remain a highly nutritious option. For a large segment of the population, cooking is the preferred method for taste and texture. Both uncooked (soaked) and cooked oats provide similar general health benefits related to beta-glucan, a soluble fiber that supports heart health and blood sugar regulation.
Uncooked vs. Cooked Oats: A Comparison Table
| Feature | Uncooked (Soaked) Oats | Cooked Oats |
|---|---|---|
| Processing | Kilned (heat-treated) but not boiled. | Kilned, then cooked with heat by the consumer. |
| Preparation | Soaked in liquid for several hours or overnight. | Boiled in water or milk until soft. |
| Texture | Chewier and firmer, ideal for overnight oats or granola. | Softer, creamier, and mushier, like traditional porridge. |
| Resistant Starch | Higher levels, which can promote gut health. | Lower levels due to cooking. |
| Nutrient Absorption | Soaking reduces phytic acid, enhancing mineral bioavailability. | Phytic acid is less of a concern, but some heat-sensitive nutrients may be lost. |
| Digestibility | Easier to digest than dry oats, but can be harder than cooked for some. | Generally easier to digest for most people. |
| Glycemic Index | Lower, contributing to more stable blood sugar levels. | Higher than uncooked oats due to starch breakdown. |
How Oat Types Differ in Processing
Not all oats are created equal when it comes to processing, which influences their texture and cooking time.
- Oat Groats: The least processed form after the hull is removed. They are kilned but left whole, requiring the longest cooking time.
- Steel-Cut Oats: Oat groats are cut into smaller pieces by steel blades. They retain a chewy texture and require a longer cooking time than rolled oats.
- Rolled Oats (Old-Fashioned): Oat groats are steamed and then rolled into flat flakes, which shortens their cooking time. This type is most commonly used for overnight oats.
- Instant Oats: The most processed variety. They are pre-cooked, dried, and rolled very thin, allowing them to cook almost instantly. This intensive processing can lead to a mushier texture.
Conclusion
In summary, while the 'raw oats' you buy at the store are not strictly raw due to heat-stabilization during processing, they are perfectly safe and healthy to consume uncooked after proper preparation. The key is to soak them to improve digestibility and reduce phytic acid. Whether you prefer your oats cooked into a creamy porridge or soaked overnight for a quick, nutrient-dense breakfast, both forms offer significant health benefits, especially in promoting heart and gut health. The best choice ultimately depends on your personal taste and health goals, as both are excellent additions to a balanced diet.

Key Takeaways
- Not Truly Raw: Commercial oats undergo a heat-stabilization process (kilning) and are not considered truly raw food.
- Safe When Uncooked: Soaking commercially-processed oats makes them safe and easy to digest without boiling.
- Soaking is Key: Preparing uncooked oats by soaking them overnight breaks down phytic acid, which improves nutrient absorption.
- Nutrient Differences: Soaked oats offer higher resistant starch and certain heat-sensitive vitamins, while cooked oats may offer different benefits.
- Versatile Preparation: Oats can be safely incorporated into a healthy diet either by cooking or by soaking for overnight preparations.
