Overview

Total fiber refers to the combination of soluble and insoluble fibers found in plant-based foods. Soluble fiber dissolves in water to form a gel-like substance, while insoluble fiber does not. Both types of fiber are crucial for maintaining a healthy digestive system, regulating blood sugar levels, and supporting heart health.

Key Benefits

Promotes Digestive Regularity

Insoluble fiber adds bulk to the stool, which helps to prevent constipation and promote regular bowel movements.

Supports Heart Health

Soluble fiber can help to lower LDL (bad) cholesterol levels and reduce the risk of heart disease.

Aids in Weight Management

Fiber-rich foods are more filling, which can help to reduce overall calorie intake and support weight management.

Regulates Blood Sugar Levels

Soluble fiber can slow the absorption of sugar, which helps to prevent spikes in blood sugar levels after meals.

Dosage & How to Take

The recommended daily intake of total fiber is 25 grams for women and 38 grams for men under the age of 50. It is best to obtain fiber from a variety of whole foods, such as fruits, vegetables, whole grains, and legumes.
