You’ve probably heard it before from your doctor, a parent, or that health-conscious friend: Eat more fibre! But do you know why dietary fibre is so important for your health?
Yes, fibre is an excellent way to fight constipation and promote regularity. But adding more fibre to your diet can also help you lose weight, lower your cholesterol, control blood sugar levels, improve your gut health, and more.
What is Dietary Fibre?
Dietary fibre is the part of plant-based foods your body can't digest or absorb. Instead, it passes mostly intact through and out of your body, absorbing water and bulking up your stool along the way.
There are two types of fibre: insoluble and soluble.
- Insoluble fibre, or not-dissolvable fibre, mostly serves as a bulking agent for your stool. It helps promote the movement of material through your digestive system, but it does not significantly contribute to weight loss. Wheat, vegetables, and seeds are good sources of insoluble fibre.
- Soluble fibre, or dissolvable fibre, plays an important role in digestion and metabolism, assisting the body in maintaining a healthy weight. It does this by feeding the flora comprising your microbiome (the trillions of bacteria living in your gut that are responsible for breaking down food, among many other amazing functions). Soluble fibre can be found in fruits, oats, legumes and barley.
Both types of fibre are important for your health. But if your goal is to lose weight and boost your metabolism, make sure you are adding plenty of soluble fibre to your diet.
How Much Fibre Should You Eat in a Day?
How much fibre you should eat in a day depends on your biological makeup. In general:
- Women should try to eat at least 21 to 25 grams of fibre a day.
- Men should aim for 30 to 38 grams of fibre a day.
As you increase your fibre intake, make sure you drink plenty of water to prevent gas, bloating, and constipation.
