Soluble vs Insoluble Fiber: What’s the Difference?

Fiber is an important component of any healthy diet! Luckily, finding delicious food with fiber benefits isn’t too hard. Even though there are lots of options out there, it’s essential to make a conscientious choice to eat more of what’s good for you!

On your fiber journey, you’ll run into lots of options, but to make the best decision, you’ll want to know the benefits of each type of fiber. That’s where we come in! Keep reading to learn about the difference between the fibers in your food. 

Understanding soluble and insoluble fiber

Soluble and insoluble fiber both have health benefits. You really can’t go wrong, but if you are hoping to reach specific health goals, you’ll want to consider their differences. 

Fiber is considered a complex carbohydrate and is found in many plant-based products, like wheat, fruits, and vegetables. As a complex carbohydrate, it won’t raise your blood sugar in the way simple carbohydrates often do. 

Soluble fiber can dissolve in water. In your colon, it becomes a gel-like substance that slows down digestion and releases a few calories in the process. It can help lower your blood and cholesterol levels. It’s also been linked to preventing diabetes. 

Insoluble fiber does not break down in your stomach. Instead, in your digestive tract, it attracts water which makes stool softer and easier to pass. It can also help with insulin sensitivity and prevent diabetes. Since it doesn’t break down the same way that soluble fiber does, it has no calories. 

Benefits of fiber

Most foods that contain fiber contain both soluble and insoluble fiber. Fiber, in general, has a lot of additional benefits. 

First, it can help support healthy weight management as it contributes to feeling satiated for longer. It also lowers the risk of heart disease, diabetes, and certain cancers such as colon and breast cancer. Finally, It can assist in balancing blood sugar and cholesterol levels.

With so much to offer, everyone can benefit from adding a bit more fiber to their meals!
