About FiberCrave
FiberCrave is a free online toolkit that helps you hit your daily fiber goal. We started it for a simple reason: most adults get only about half the fiber they need each day, and the information out there is either too technical or buried inside diet apps that want your money.
What we offer
- Fiber calculator — a quick estimate of your daily fiber target based on widely used nutrition guidelines.
- Food database — thousands of foods with fiber content per 100 g, sourced from the USDA.
- Supplement database — single-ingredient fiber supplements with plain-language evidence summaries.
- Guides — practical articles on fibermaxxing and high-fiber eating, written for real life, not labs.
Our data
Food nutrition data comes from the USDA FoodData Central (SR Legacy), a public dataset published by the U.S. Department of Agriculture. Values are shown per 100 g as published; actual products vary by brand and preparation.
