Benefits of Fiber

Fiber supports digestive health, helps control blood sugar, lowers cholesterol, and promotes satiety for weight management.

The Daily Fiber Intake Formula

This formula is based on the USDA dietary guidelines, which recommend consuming 14 grams of dietary fiber for every 1,000 calories of food energy.

Step-by-Step Fiber Target Calculation

Let's calculate the daily fiber target for an individual consuming a 2,500-calorie diet.

1
1. Divide Calories by 1,000
Find how many 1,000-calorie blocks are in your daily diet.
2,500 / 1,000 = 2.5
2
2. Multiply by the Target Rate
Multiply the calorie blocks by the recommended 14g rate.
2.5 × 14 = 35 grams
3
Resulting Daily Target
This represents your daily fiber intake goal.
35 grams
