Viscous fiber is a type of soluble fiber found in plant foods that forms a gel and isnt absorbed in the gut. It can bind cholesterol in the gut, preventing its absorption into the bloodstream, and can help lower LDL-C by 5-11 points. Viscous fiber is also great for weight loss because it promotes fullness and reduces appetite. Foods high in viscous fiber include whole grains, vegetables like broccoli and carrots, legumes like black beans and lentils, and nuts and seeds like almonds and chia seeds. Aim for 5-10 grams of viscous fiber a day as part of your total fiber intake. When increasing fiber intake, its important to add it slowly to prevent feeling bloated and gassy, and to drink more water.
