The latest nutrition talk is often all about increasing protein and fat, but fiber doesn’t usually get the attention it deserves.
Fiber is a low-key superhero when it comes to your health. Found in foods like beans, veggies, fruits, and nuts, fiber is super important for your digestive system. But, it’s also linked to a ton of preventative health benefits beyond just making you poop.
Unfortunately, most peeps don’t eat enough fiber. Here’s why fiber is a super important part of your diet and how to get more of it.
What is fiber?
Dietary fiber is a carbohydrate found in plant-based foods that your body can’t digest. It’s usually split into two groups: soluble and insoluble fibers. But keep in mind that each type of fiber is unique, even though some fibers share similar properties. Let’s break it down.
Soluble fiber
Soluble fibers are dissolvable in water and there are three different soluble fiber categories:
1. Soluble, viscous/gel-forming, readily fermented fibers
These soluble fibers thicken up when exposed to water and are easily fermented by gut bacteria. They are beneficial for blood sugar control and may help lower cholesterol levels. However, they’re not helpful for constipation because they don’t have a laxative effect.
Examples include β-glucans from oats and guar gum.
2. Soluble, viscous/gel-forming, nonfermented fibers
These soluble fibers thicken in the presence of water but resist fermentation. They have the same benefits as soluble, viscous, and fermentable fibers. But, since they’re resistant to fermentation in the large intestine, these fibers can help constipation and diarrhea. 💩
An example is psyllium.
3. Soluble, nonviscous, readily fermented fibers
These types of fibers are soluble in water, but don’t thicken. They’re also easily fermented by gut bacteria. They may help boost beneficial bacteria in the gut while limiting the growth of potentially harmful gut bacteria.
Examples include inulin, oligosaccharides, and resistant starches.
Insoluble fiber
Unlike soluble fibers, insoluble fibers don’t dissolve in water. Plus, they don’t thicken in the presence of water and they’re poorly fermented by gut bacteria.
Insoluble fibers can have a laxative effect and help increase the water content of stool to make you go. However, some types of this kind of fiber, like finely ground wheat bran, can dry out your poo and stop things up.
Another example of insoluble fiber is cellulose, a type of carb found in plants.
Benefits of fiber: Why it’s so dang important
A high fiber diet offers all sorts of health benefits. Plus, certain types of fiber can help you get a much needed No. 2. Here are some of the most well-known benefits of fiber.
FYI: There’s A BUNCH of different fibers found in food, plus tons of fiber supplements. These benefits are related to fiber in general.
Heart health
Packing fiber into your meals and snacks is a smart way to keep your heart in top condition. Fiber helps reduce blood fat levels, which can lower heart disease risk.
A large 2017 umbrella review found that folks with the highest fiber intake had a lower risk of developing heart disease and dying from heart-related conditions. This was compared to those who ate the least amount of fiber.
Digestion and gut health
Loading up on fibrous foods helps feed the good bacteria in your gut and helps keep your digestive system healthy.
Fermentable soluble fibers can be broken down by gut bacteria, releasing beneficial compounds and contributing to a healthy gut bacteria balance while insoluble fibers help keep bowel movements regular.
Soluble, viscous, nonfermentable fibers and insoluble fibers are helpful for relieving constipation because of their laxative effect.
Research shows that following a high fiber diet can also help protect you from developing conditions that impact the digestive system. This includes colon cancer, diverticulitis, and Inflammatory bowel disease (IBD).
Healthy body weight
Adding high fiber foods to your meals and snacks may help increase feelings of fullness. Just make sure to balance fiber with protein and healthy fats. This will help fuel your body and keep you satisfied between meals.
Many studies have linked high fiber diets with healthy body weight.
Research shows that diets high in fibrous foods like beans, vegetables, whole grains, and fruits are linked to healthier weight than diets low in these foods.
More fiber-related health benefits
Fiber-rich diets have been associated with many more health benefits, including decreased risk of certain cancers, metabolic syndrome, and type 2 diabetes.
Adding more high fiber foods to your diet may help improve blood sugar regulation, cholesterol and triglyceride levels, and blood pressure.
Following a high fiber diet also helps reduce inflammation and may even help boost your mood and protect against depressive symptoms.
