The 5 Best Whole Grains to Help Improve Insulin Resistance, Recommended by Dietitians 

Whole grains can be beneficial for managing insulin resistance due to their fiber content, which helps regulate blood sugar levels.  

Here are five whole grains recommended by dietitians for their potential to improve insulin resistance: 

Oats are a great source of soluble fiber, specifically beta-glucans, which can help slow down the digestion and absorption of carbohydrates. This, in turn, helps stabilize blood sugar levels and improve insulin sensitivity. 


Quinoa is a versatile whole grain that contains both fiber and protein. It has a low glycemic index and provides a steady release of glucose into the bloodstream, making it a good choice for those looking to manage insulin resistance. 


Brown rice is a whole grain that retains the bran and germ layers, providing more fiber and nutrients compared to white rice. The fiber in brown rice can help regulate blood sugar levels and improve insulin sensitivity. 

Brown Rice: 

Barley contains a type of soluble fiber called beta-glucan, similar to oats. This fiber helps slow down the absorption of sugar and can contribute to better blood sugar control. Barley is also rich in nutrients like magnesium, which is associated with improved insulin sensitivity. 


Despite its name, buckwheat is not a type of wheat but rather a seed. It is gluten-free and a good source of fiber, particularly soluble fiber. Buckwheat consumption has been linked to improved insulin sensitivity and lower blood sugar levels. 


When incorporating these whole grains into your diet to manage insulin resistance, it's essential to focus on overall dietary patterns and choose a variety of nutrient-dense foods.  

Additionally, portion control plays a crucial role, as excessive calorie intake can contribute to insulin resistance. 

Consulting with a registered dietitian or healthcare professional can help tailor dietary recommendations to individual needs and health goals.
