High-Fiber Diet: What You Need to Know

If you want to eat healthily, you should focus on lots of fiber in your daily diet. These indigestible fibers keep you full longer and support your gut health. We want to provide you with all the knowledge you need for a fiber-rich diet.

What Exactly Are Fibers?

Fiber consists of indigestible carbohydrates found in plant-based foods. They are essentially "bulk" for the diet, providing no energy. Nevertheless, they play an important role in digestion and promote not only your gut health but also your personal well-being.

We distinguish between soluble and insoluble fibers. Soluble fibers dissolve in water and form a gel-like substance. They can bind substances like cholesterol and are found more in oats or beans.

Insoluble fibers increase stool volume and are found, for example, in whole grain products or nuts.

Summary of the Health Benefits of Fiber

A fiber-rich diet is recommended for good reason, as it offers numerous health benefits.

Promoting Digestion

Fiber-rich foods can greatly support your digestion. They help regulate bowel movements and can reduce constipation and other symptoms. As the volume of intestinal contents increases, the intestines have to move more, so intestinal peristalsis is promoted.

Better Blood Sugar Control

After a meal, your blood sugar level can rise more or less quickly and sharply. In principle, slow and steady increases are desirable, which is why complex carbohydrates and fiber are preferable to simple carbohydrates and sugars. By eating fiber-rich foods, you can maintain better blood sugar control.

Weight Control

An out-of-control blood sugar level can promote cravings, which is disadvantageous for weight control. Additionally, fiber keeps you full longer, making it easier to establish healthy eating habits.

Benefits for heart health

LDL cholesterol is considered unhealthy cholesterol. It can negatively affect your heart health. Dietary fibers can help lower blood levels of LDL cholesterol, which in turn can promote your heart health. For example, your blood vessels may have fewer deposits.

Your gut will thank you

Dietary fibers support your gut health in many ways. For example, they help maintain a healthy gut flora by serving as food for beneficial bacteria. Variation in fiber selection is helpful for this.

High-fiber foods: Natural sources of healthy dietary fibers

If you want to eat a high-fiber diet, we recommend varied and natural sources for your dietary fibers. Fibers should also become an integral part of your diet. Taking a glass of psyllium husks every evening is indeed a good and important step. However, it is more important to replace simple carbohydrates in your diet with complex ones. For this, you can rely on the following sources of dietary fiber:

• Whole grain products like whole grain bread, brown rice, or whole grain pasta
• Vegetables like broccoli, spinach, or carrots 
• Fruits like apples with skin or berries
• Legumes like beans, lentils, and peas
• Nuts and seeds, especially chia seeds, flaxseeds, oat bran, and walnuts
• Grains like barley, wheat bran, buckwheat, or amaranth
• Dried fruits like raisins or apricots
• Potatoes with skin (including sweet potatoes)
• Popcorn (unsweetened)
• Vegetable peels
• Seaweed like nori or wakame

By the way: Since dietary fibers can ferment in the large intestine, they can cause increased gas. However, this is a good sign!

High-fiber diet: Frequently asked questions

What are dietary fibers?

Fibers are indigestible and complex carbohydrates. They pass through your gut without being digested. This increases the volume of the intestinal contents, which causes more movement, stimulating the so-called gut peristalsis. Additionally, fibers can serve as food for healthy gut bacteria and thus promote your gut flora.

How much fiber per day?

The recommended fiber intake varies depending on certain factors. Gender, age, and individual needs should be considered. As a guideline, adult men should consume between 30 and 40 grams of fiber per day. Women often need about 25 grams per day. You should discuss your exact needs with your doctor.

What has a lot of fiber?

Where are many fibers found? This question can be easily answered. Simply rely on the following foods:

• Seeds and nuts
• Whole grain products
• Fiber-rich grains
• Algae
• Vegetables (with skin)
• Fruit (with skin)
• Legumes

Why are fibers important?

Are fibers good? Yes! They support your gut health in many ways, which is why fibers should be integrated into your daily diet. They increase your gut motility, promote your gut flora, help with blood sugar and weight control, and can even positively influence heart health. Some studies also suggest that the immune system can be strengthened and that colon cancer may possibly be prevented.

Which fibers are good for the gut?

All! Feel free to rely on a healthy mix of soluble and insoluble fibers. Cellulose, lignin, resistant starch, pectin, inulin, and oat beta-glucan are examples of dietary fibers.
