It’s no secret that high-fiber foods provide many health benefits. Aside from helping you maintain a healthy weight and making your good gut bacteria thrive, fiber can also prevent diseases such as diabetes, heart disease, or obesity. Read on for all the health benefits and where to find the best fiber-rich options!

Top 15 amazingly healthy high-fiber foods

What is fiber and how much should I have?

The fiber found in food is a type of carbohydrate that your body can’t digest. It can be soluble, meaning that it can dissolve in water, or insoluble, meaning that it passes down your digestive system intact. They both have their own health benefits and most fiber-rich foods contain each of them in different proportions.

The recommended fiber intake is 14 grams for every 1000 calories consumed. On average, that’s between 25 and 38 grams daily for adults. Most Americans only consume half of that amount, which is worrying, considering all the health benefits fiber holds. 1

Amazing health benefits of high-fiber foods.

Fiber is packed with great health benefits.

Firstly, it can help you feel fuller for longer after meals, because soluble fiber slows down the speed at which foods are digested. Insoluble fiber can also fill up space physically in your stomach (and doesn’t give you any calories) meaning you are likely to eat less. Furthermore, it can decrease nutrient absorption resulting in lower calorie intake. This can be a true aid for people trying to lose weight. 

In addition, it has been shown that fiber-enriched diets reduce cholesterol long term, and improve glycemic control and insulin sensitivity. Sure enough, soluble fiber slows down the digestion and absorption rate, preventing spikes in blood-sugar levels and insulin. Fiber-rich foods could also have protective effects on colon cancer and coronary heart disease.

On one hand, soluble fiber creates a type of gel when it dissolves, which can improve digestion. It is also beneficial to your gut bacteria, which can use it to make fatty acids. These fatty acids could have positive effects on your body, such as reducing inflammation2

On the other hand, insoluble fiber stays more or less intact: it absorbs fluids in the gastrointestinal tract and sticks to byproducts of digestion. This improves stool aspect, promotes bowel health, and prevents constipation. 

So fiber has many important benefits for your body— but where can you find it?
