What Is High Blood Pressure & Why Is It A Concern

High blood pressure is when the force put on the artery walls by the blood is consistently too high.

There are many serious health concerns associated with high blood pressure including heart attack, stroke, and kidney disease (2).

Having high blood pressure can damage arteries and cause an accumulation of bad cholesterol. This condition is called atherosclerosis. It narrows the arteries which puts strain on your heart since it must work harder to pump your blood. This increases the risk of heart attack, stent placementsperipheral artery disease, or heart failure. 

There is also a greater risk for stroke if the brain is not supplied with enough blood flow and oxygen (which is carried in the blood). If the arteries that supply blood to the brain become damaged, this reduced blood flow may occur and lead to a stroke

Finally, high blood pressure can lead to kidney disease. The kidneys are responsible for filtering our blood to remove any harmful substances through our urine. If there is damage to the arteries involved in the filtration process, the kidneys will not be able to function properly. 

These are just a few of the main concerns with high blood pressure, but there are many other issues that can potentially arise. 

Now that we know that high blood pressure is something we want to manage. Let’s see if oats can lower blood pressure.

It is recommended that those with high blood pressure follow a “heart healthy” eating pattern, like the DASH diet. One of the components of the DASH diet is to include whole grains and unprocessed foods. 

Oats are a great option for an unprocessed, whole grain that you can include in your diet.

Oats are good for lowering blood pressure mainly because they contain a type of soluble fiber called beta-glucan that will be discussed in the next section. 

Nutritional Benefits Of How Oatmeal Can Lower Blood Pressure

Fiber Content

Oats are rich in both soluble and insoluble fiber which both help with digestion. Insoluble fiber helps to build bulk and soluble fiber forms a gel-like substance and helps to slow the digestion process. 

Oats are rich in the soluble fiber, beta-glucan, which has been shown to have health benefits including aiding digestion and helping to lower blood sugar and blood cholesterol (3). An essential component of the Portfolio diet.  Be sure to check out these oatmeal recipes to lower cholesterol

There is research that suggests beta-glucan can also play a significant role in lowering blood pressure (4). Thus, oatmeal and lower blood pressure. 

Soluble Fiber And Cholesterol Lowering 

As mentioned above, soluble fiber can help to lower cholesterol. It does this by binding cholesterol during the digestion process so that it can be excreted in the stool rather than reabsorbed into the bloodstream (5).

Lowering cholesterol can help to lower blood pressure, prevent atherosclerosis, and stroke. Here is a great list of oat bran recipes that can help lower cholesterol.

So why else does oatmeal lower blood pressure? Oats contain some key minerals that may also play a role in lowering blood pressure.

Oats are a good source of potassiumcalcium, and magnesium, all of which play a role in relaxing muscles. This includes the blood vessels, and their relaxation helps to control blood pressure (6).

Can Reduce Inflammation

Oats contain antioxidants called avenanthramides which may help to reduce inflammation caused by harmful free radicals. Free radicals are unstable molecules that cause damage to the body andcan contribute to high blood pressure. 

Antioxidants are needed to prevent the damage that the free radicals can cause (7). Check out this comprehensive list of anti-inflammatory foods for heart disease to add more foods to your diet.

Oats And High Blood Pressure Diet 

DASH stands for “Dietary Approaches to Stopping Hypertension”. The DASH diet is an eating pattern recommended for lowering blood pressure and helping to reduce the risk of heart disease. Oats are part of this blood pressure lowering diet! 

One of its suggestions is to eat 7-8 servings of whole grains per day. 

Oats are unprocessed whole grains that are high in fiber. Including oatmeal in your diet is a great way to get in a healthy serving of whole grains. Thus, oatmeal can lower blood pressure.

Other Health Benefits Of Oatmeal

The other health benefits discussed are all related to the high fiber content of oats. 

Better Digestion

Fiber is very important for healthy digestion, especially when it comes to preventing constipation. 

As mentioned earlier, oats contain both soluble and insoluble fiber which have different roles in digestion.

Soluble fiber will form a gel-like substance in the digestive tract, helping to retain water. It also helps to slow down digestion and nutrient absorption (8).

Insoluble fiber, on the other hand, is what helps to build bulk and make your stool easier to pass.

Blood Sugar

Fiber plays an important role in controlling blood sugar levels. Having high blood sugar can pose similar health risks as high blood pressure.

In our bodies, carbohydrates are broken down into glucose, which will be absorbed into the blood from the digestive tract. Glucose is the sugar that is referred to when we talk about blood sugar levels. 

After we eat a meal with carbohydrates, our blood sugar levels will rise due to the increase in glucose.

Fiber will not cause this rise in blood sugar because it is a carbohydrate that does not get broken down into glucose. Because of this, it helps to alleviate spikes in blood sugar after a meal (9).

Weight Management

Since fiber slows down digestion and prevents spikes in blood sugar, it helps you to feel full for longer after eating. This can help to prevent overeating which will help to maintain a healthy body weight when done alongside other healthy lifestyle choices.


Studies have suggested that consuming a diet rich in fiber may help to lower the risk of breast cancer and colon cancer. Since fiber is often consumed with a variety of other healthy foods, this may be a factor contributing to its ability to lower the risk (10).
