Dr. C here,
About a month ago I said that now is a good time to make peace with carbohydrates. They are inexpensive, they have a long shelf life, and they may be the last foods on the shelf in the grocery store.
Many of them also have dramatic health benefits – oats are one of the best examples.
You can find many different types of oats:
- Whole oat groats
- Steel-cut oats
- Old fashioned rolled oats
- 1 minute rolled oats
- Instant oats
If you are avoiding gluten, oats are naturally gluten-free. Some companies process oats and wheat on the same machines and can have gluten from wheat as a contaminant in the oats.. Many do not and can certify their oats as gluten-free foods.
The serving size is 1/4 cup dry for whole oat groats and steel-cut oats, and 1/2 cup dry for rolled oats.
Which type is best? Truth be told the differenced between them are subtle. The nutrients, fibers, and beta-glucans are pretty much the same in any of them. The rate of absorption is slightly higher for instant oats than for others but they are still a low-glycemic food.
Most of the differences come down to taste, preference, convenience, and availability.
Whole oat groats are my favorite but for whatever reason, I’ve been using steel-cut and old fashioned and steel-cut more often lately.
It is really handy to cook them in advance. Stovetop and microwave both work fine. The crockpot works well for whole oat groats. For them, I do 2 cups with 8 cups of water and let them cook overnight on low.
I usually do steel-cut oats on the stovetop. Usually 1 cup of oats with 3 and a 1/2 cups of water. I’ll bring them to a low boil, reduce the heat to a low simmer and let cook lightly covered for 1/2 hour.
Rolled oats I usually cook in the microwave. I’ll use a pyrex much larger than needed because otherwise they often overflow while cooking – no fun. Typically I’ll do 1 cup of oats with 1 3/4 cups of water and microwave for 3 minutes. (Read: Did you know microwaves make less powerful radiation than a gas burner?)
Beta-glucans are powerful compounds that boost the immune system and regulate blood sugar. Oats are among the highest dietary sources of beta-glucans.
They also have a unique property in that they form a hydrocolloid gel in the intestinal tract. This gel has been documented to create a more gradual absorption of calories from the oats as well as anything else you ate with them. It also helps to form short-chain fats that improve the health of the intestinal lining.
Have you ever heard that oats spike your blood sugar? If your food went straight into your bloodstream and your blood glucose only came from your food, that would be true. But the body just does not work like that.
It turns out that the quicker you absorb a meal, the more glucose you make from your liver. Slowly absorbed foods like oats can lower most peoples’ blood sugar more than quickly absorbed meals with less carbohydrates like those comprised of high amounts of oil and meat.
Oats are not just for breakfast. Enjoy this recipe for steel-cut oat risotto!
