Fiber is a crucial component of a healthy diet, offering numerous benefits from improved digestion to weight management and heart health. If you’re looking to increase your fiber intake, this guide will provide you with a detailed list of what’s high in fiber foods, along with practical tips on how to incorporate them into your daily meals.
The recommended daily fiber intake varies based on age and calorie consumption. The Dietary Guidelines for Americans suggest 14 grams of fiber for every 1,000 calories consumed daily for individuals aged 2 and older. For younger children (12-23 months), the guideline is approximately 19 grams per day.
Why is Fiber Important?
Fiber plays several essential roles in maintaining overall health:
- Promotes Digestive Health: Fiber helps regulate bowel movements and prevent constipation by adding bulk to the stool, facilitating its passage through the digestive tract.

- Lowers Risk of Chronic Diseases: A diet rich in fiber is associated with a reduced risk of heart disease, type 2 diabetes, and certain types of cancer. Fiber can help lower cholesterol levels and regulate blood sugar levels.
