What is the daily recommendation of fiber intake for adults?

The recommended daily fiber intake for adults varies based on several factors, but generally, a range of 20 to 30 grams is established as an adequate intake level. Fiber is crucial for maintaining digestive health, regulating blood sugar levels, and reducing the risk of chronic diseases such as heart disease and diabetes. Consuming sufficient fiber can help prevent constipation and promote a healthy gut microbiome.

This recommendation considers both soluble and insoluble fiber, both of which play important roles in health. Soluble fiber helps manage cholesterol and blood glucose levels, while insoluble fiber aids in digestive movement and helps prevent constipation. Thus, the recommendation aims to ensure that adults receive enough of both types to support overall health and well-being.

Other values presented in the options do not align with established dietary guidelines, clearly indicating that they fall short of promoting optimal digestive health and may not meet the body's daily nutritional needs for fiber.
