Oats are one of the greatest source for important vitamins, minerals, fibers, and antioxidants. Studies have shown that oats and oatmeals can bring a lot of health benefits.
This whole-grain food is also known as “Avena Sativa” scientifically. Here are some of the known benefits for eating your oatmeal for breakfast.
They’re Incredibly Nutrition Packed
Oats are good source of carbs and fibers with their nutrient composition is well-balanced.
They also have more proteins and fats than most other grains.
From a half cup (78grams) serving of dry oats, you’ll get about 51 grams of carbs, 14 grams of proteins, 5 grams of fats and 8 grams of fiber with only 300 calories.
Apart from that, they’re also loaded with important minerals, vitamins and antioxidants compounds such as Manganese, Magnesium, Phosphorus, Copper, Iron, Zinc, Folate, Vitamin B1 (thiamin), Vitamin B5, and smaller traces of calcium, potassium, vitamin B6, and vitamin B3(niacin).
Powerful Soluble Fiber - Beta Glucan
When we talk about oats, fiber has always been the main topic element.
Particularly, whole oats come with large amount of Beta-Glucan, a type of soluble fiber that can dissolves partially in water and form a thick gel-like solution in our gut.
It also help to reduce blood sugar and insulin response, increase growth of beneficial bacteria in our digestive tract.
The good news for those who are watching or reducing their weight, beta-glucan increases the feeling of fullness after your oatmeal breakfast.
Lower LDL Cholesterol (bad cholesterol)
You’ve probably heard of how LDL cholesterol being the major risk in heart disease.
Multiple studies have shown that the Beta-glucans contained in oats are effective in reducing both the bad cholesterol and overall cholesterol level.
It encourages the excretion of cholesterol-rich bile from your liver, which in turn reduce the circulating cholesterol in our blood.
There’s also studies that shows antioxidants in oats can work with Vitamin C to prevent LDL cholesterol oxidation (which causes damages in tissues and can increase the risk of heart attacks and strokes).
Lack of fibres are commonly associated with constipation. More often than not, elder people experience infrequent, or irregular bowel movements that are hard to pass.
Although laxative may help to relieve the issue, long term usage also comes with side effects like unhealthy loss of weights and reduces quality lifestyle.
Studies shown that, oat bran (the fiber-rich external layer of grain) can help to relieve constipation in elder people. With the side benefits of also helping them stay healthier.
Rich in Antioxidants
Oats are well-known for its high antioxidant and beneficial plant compounds like polyphenols.
One of the more unique group of antioxidant, Avenanthramides, are solely found in whole oats.
This group of antioxidant act as anti-inflammatory. It is also especially effective in lowering blood pressures by improving the production of nitric oxide.
Nitric oxide may helps with better blood flow by dilating the blood vessels.
Ferulic acid is another powerful antioxidant known to help with anti-aging; it is also found in large amount in oats.
Improve Blood Sugar Control
Significantly elevated blood sugars is a sign of Type 2 Diabetes. This is usually the result of reduced sensitivity to insulin.
Oats are also known to help improve insulin sensitivities. The beta-glucan forms a thick gel which delays the emptying of foods in stomach and absorption of glucose in the blood stream.
Helps You Stay Full Longer
That powerful soluble fiber that we mentioned above, Beta Glucan is great at delaying the time your stomach takes to empty foods. In turn, it helps you to stay full for longer period of time and reduce your calorie intake.
The Beta-Glucan is also known to promote the peptide YY (satiety hormone) release in your gut that responds to eating. One of the key to feel full longer with oatmeals though, was to add in enough proteins when you eat them.
There’s just so much benefits from these whole grains itself and yet it is so simple to prepare.
If you include toppings like fresh berries, fruits and yogurts, there’s even more health benefits for such simple breakfast.
Now that we know the benefits, the next natural thing to ask is: which type of oats are the healthiest?
All oats are started as groats, the whole, un-processed grains.
Before being processed, most of these grains are roasted at very low temperature. This helps to deactivate enzymes that causes oats to go rancid. It also make them more shelf-stable and adds a nice toasty flavor.
There are three main types of processed oats: the rolled oats (old-fashion), Steel cut oats (Irish) and the Instant Oats (Quick oats).
The difference between them is really just how much they’ve been processed. The result is both the varying texture and cook times.
The steel cut oats are sometimes referred to Irish oats.
The whole oat groats are chopped up into several pieces by a sharp steel cutter. They look like rice that’s been cut into pieces.
Steel cut oats takes the longest to cook and has more chewy texture. It’s a good option to add texture to stuffings, meatloaf or even savory congee as an alternative to rice.
Scottish Oats: Some also refers steel cut oats as Scottish oats. Traditional Scottish oats are stone-rinded to create broken bits at varying sizes. It results in creamier porridge than steel cutting.
Often called the old-fashioned oats or whole oats. They look like flat, irregular round and slightly textured discs.
The whole groat was first steamed soft, then pressed to flatten.
Rolled oat cooks faster than steel-cuts, absorb more liquid, and hold their shapes relatively well during cooking.
In addition to be heated for a warm breakfast bowl, rolled oats are also commonly used in granola bars, cookies, muffins, and other baked goods.
Instant oats can be used in place of rolled oats, although the cook time will be much less, and the final dish will not have as much texture.
The instant oats sometimes referred to as “quick oats” are the most processed of the three varieties.
They are pre-cooked, dried, and then rolled and pressed slightly thinner than rolled oats.
They can cook more quickly than steel-cut or old-fashioned oats, but retain less of their texture, and are often results in more mushy form.
All these oats varieties has gone through different level of processing. The results are different textures and time required to cook.
The Instant Oats is the most processed and possibly have lost a fair bit of nutritional value in the process. While the steel-cut and rolled oats would have the most nutrients.
Overall though, since they are all made from whole oat groats, they all have the same nutritional profile.
Ultimately, if you like sweet, chewy texture with nutty taste, try the steel cuts. If you prefer the oatmeal to be creamy and smooth, then definitely go for the instant oats.
No matter the type, there should only be one ingredient listed — whole-grain oats, when you buy them off the shelves.
Some flavoured instant oats can also come packed with sugars, sodiums, or other artificial ingredients.
We would suggest to avoid those and opt for the plain instant oat instead. You can after all add toppings like fresh berries, Greek yogurt, almond butter or even fried eggs.
