What Defines a Raw Food Diet?
At its core, a raw food diet, or raw foodism, emphasizes eating foods that are unprocessed and uncooked. The primary rule is that no food can be heated above a certain low temperature, typically ranging from 104°F to 118°F (40°C to 48°C). The philosophy behind this dietary approach suggests that cooking food above this temperature destroys essential enzymes and nutrients. This often means that common staples like grains and legumes must be either soaked or sprouted instead of cooked. The application of this rule to oats is where confusion arises, as their journey from field to package involves processing that doesn't align with a strictly raw food definition.
The Processing of Commercial Oats
Most oats you buy in a grocery store, including old-fashioned rolled oats, quick oats, and instant oats, have been heat-treated. After harvesting, the inedible hull is removed to create the oat groat. To make these groats palatable and shelf-stable, they are steamed and then flattened into flakes. This steaming process, known as kilning, is crucial for deactivating the enzymes that would otherwise cause the oats to go rancid quickly due to their high fat content. Therefore, while you can eat them 'uncooked' by simply soaking them, they are not technically 'raw' in the way a raw foodist defines the term.
Rolled Oats vs. Steel-Cut Oats: Which is Less Processed?
For those on a raw diet, understanding the different types of oats is essential. While all commercial oats undergo some level of heat-processing, the degree varies by type.
- Rolled Oats: These are the most common and undergo the steaming and flattening process. They are considered safe for consumption without further cooking due to this process.
- Steel-Cut Oats: Also known as Irish or pinhead oats, these are simply oat groats that have been cut into smaller pieces. They are not flattened and undergo a lesser degree of processing than rolled oats, but they are still heat-treated to prevent rancidity. They have a tougher, chewier texture and a nuttier flavor.
- Oat Groats: These are the least processed form of edible oats, being the whole, hulled grain. They still undergo a stabilizing heat treatment at the mill.
Because all forms of commercial oats are heat-treated, a strict raw foodist might consider them all off-limits. However, for many who follow a less stringent raw diet, consuming soaked rolled or steel-cut oats is an acceptable practice, as no high-heat cooking is done in the final preparation.
How to Prepare Soaked Oats for a Raw Diet
Preparing oats without cooking is a simple and effective way to enjoy them. This process, often called making overnight oats, is a staple in many raw vegan diets. Soaking is not just for texture; it also helps to break down phytic acid, an antinutrient found in grains that can inhibit the absorption of minerals like iron and zinc.
A simple soaked oats recipe involves:
- Ingredients: 1 part rolled oats, 1 part liquid (water, nut milk, or fruit juice), and optional mix-ins.
- Instructions:
- Combine the rolled oats and your chosen liquid in a jar or bowl.
- Add optional ingredients like chia seeds, dates, or spices and stir to combine.
- Cover and refrigerate for at least 2 hours, but preferably overnight.
- In the morning, stir well and top with fresh fruits, nuts, or seeds.
The Nutritional Benefits of Soaked Oats
Soaking oats makes them easier to digest and enhances their nutritional profile. The soluble fiber, beta-glucan, in oats forms a gel-like substance that can lower cholesterol and stabilize blood sugar levels. Soaked oats also contain a higher level of resistant starch compared to cooked oats. Resistant starch acts as a prebiotic, feeding beneficial gut bacteria and supporting overall gut health.
Raw vs. Cooked Oatmeal: A Comparison
| Feature | Soaked ('Raw') Oatmeal | Cooked Oatmeal (Porridge) |
|---|---|---|
| Processing | Oats are heat-treated at the factory, then soaked. | Oats are heat-treated at the factory, then cooked at high heat. |
| Texture | Chewy and firm (for rolled) or nutty and firm (for steel-cut). | Soft, creamy, and can be gooey. |
| Nutrient Profile | Higher levels of resistant starch; potentially more heat-sensitive vitamins remain. | Some nutrients, like certain B vitamins, may be reduced by high heat. |
| Digestibility | Soaking makes them easier to digest than eating dry oats, but some find cooked easier. | High heat breaks down starches, making it very easy for most to digest. |
| Phytic Acid | Soaking reduces phytic acid, improving mineral absorption. | Cooking and soaking both reduce phytic acid. |
Conclusion
Ultimately, whether you can eat oatmeal on a raw diet depends on your interpretation of 'raw.' Commercially sold oats, such as rolled and steel-cut, are safe to consume without cooking due to pre-treatment with steam. However, this processing means they are not technically raw according to strict definitions. For those who follow a flexible raw food approach, preparing soaked oats (like overnight oats) is an excellent way to include this nutritious grain. Soaking enhances digestibility and nutrient absorption, offering a delicious and wholesome addition to a plant-focused diet. For purists, exploring truly raw alternatives or simply omitting oats might be the preferred path.
