There are two forms of fibre - soluble fibre and insoluble fibre. Soluble fibre dissolves in water, so it turns into a gel-like substance. It helps you absorb nutrients by slowing down digestion.
Insoluble fibre does not dissolve in water, rather it adds bulk to the stool and acts as a brush, keeping everything moving! You’ll find both in plant products, including vegetables, cereals, seeds, and tree bark.
Studies of centenarians in the Blue Zones have shown that regular intake of high amounts of fibre is important if you want to live a long life. Eating fibre keeps you regular, and soluble fibre probiotics also help to increase the number of good bacteria in your gut, through the process of fermentation. More good bacteria means a happier gut!
If you are suffering from constipation and are eating a low fiber diet, then adding more can help. Don’t go crazy on the amount, to begin with, start slow and periodically add in more as your body adapts (otherwise you may be dealing with some unwanted side effects like bloating and gas). Remember to increase your water intake - fibre needs water to move things through! By adding fiber into your diet every day, you are promoting normal bowel and intestinal function, and the ability of your body to properly rid itself of waste.
