Low carbohydrate diets like the Keto diet have become very popular in recent times as many people look for effective methods to lose weight and improve their health. While we hear a lot about eating less calories and the numerous health benefits of protein and fats, we often overlook the importance of eating fibre to the health of our body. Cutting out carbs too much can be a problem if you are not aware of what foods contain high amount of fibre to help with digestion of fats and proteins. Research shows that people who consume high-fibre diets have much lower rates of constipation than individuals that eat a low-fibre diet, however, too much fibre may result in loose stools, bloating, or even diarrhea. Finding the right balance is the key, and eating a wide range of fresh vegetables and fruits is the key to getting this right. In this article, we will discuss what these foods are.

What Is Fibre?

Dietary fibre is a non-digestible carbohydrate found in foods.

There are two broad categories based on its water solubility:

  1. Soluble fibre: Dissolves in water and can be metabolized by the “good” bacteria in the gut.
  2. Insoluble fibre: Does not dissolve in water.

The US Food and Nutrition Board recommends a minimum daily fibre intake 38 grams per day for men and 25 grams per day for women.

Why Is Fibre Beneficial to Our Health?

Unlike other carbohydrates, fibre is not broken down and absorbed by your digestive tract. Instead, fibre passes through your system until it reaches your colon, where it is either fermented by bacteria or eliminated by the body. Plant foods & vegetables contain a combination of both soluble and insoluble fibre.

Although is well known for helping to relieve constipation, fibre has also been found to play several other health roles, these include:

  • Better diabetes control: For people with Type 2 diabetes soluble fibre can help lower blood sugar.
  • Lower LDL cholesterol levels: Both soluble and insoluble fibre may help to reduce LDL cholesterol.
  • Potential weight loss: Fibre helps you to feel full for longer and therefore prevent additional snacking.
  • Improve lung capacity: In our article about lung health we explained how people on low fibre diets were more exposed to respiratory problems.
  • Relief from irritable bowel syndrome: Insoluble fibre bulks up stool, soluble fibre seems to be more beneficial for irritable bowel syndrome.
  • Reducing gastrointestinal cancer risk: Eating enough fibre can have protective health effects for example protecting our bodies against certain cancer types, including colon cancer.

Fibre can provide our bodies with many health benefits, however for some of us a high fibre diet can cause problems. People with active diverticulitis, inflammatory bowel disease (Crohn’s disease or ulcerative colitis), or gastroparesis may need to limit fibre intake & should discuss this with your GP.

Let’s look at the best foods to eat. Below are two great videos explaining why it is so important to eat a wide variety of foods.
