Fiber Index Score™ & Grade™

Fiber Index Score™
Fiber Index Score™ (FI Score™) is a standardized measure designed to evaluate fiber in the context of the food that contains it. Rather than looking at fiber grams alone, FI Score™ begins with the relationship between dietary fiber and available carbohydrate, then incorporates defined nutritional factors to produce a single, comparable score.
How the Score Works
Fiber Index Fit™ uses a structured, patent-pending methodology that considers:
-
dietary fiber relative to available carbohydrate
-
protein density
-
sodium density
-
added sugar
-
serving-size considerations
Together, these factors produce the FI Score™, a standardized numerical expression of a food's Fiber Index profile. The scoring system is designed to be:
-
consistent and reproducible
-
comparable across foods
-
useful for everyday food decisions
-
simple enough to translate into intuitive consumer signals
Fiber Index Grade™
Fiber Index Grade™ (FI Grade™) translates the FI Score™ into a familiar A+ through F scale, making differences in Fiber Index profiles easier to recognize and compare at a glance.
Understanding the Grade
The FI Grade™ represents progressively stronger Fiber Index profiles:
-
A+ / A — highest FI Score™ ranges
-
B — higher FI Score™ range
-
C — intermediate FI Score™ range
-
D / F — lower FI Score™ ranges
A higher grade reflects a higher Fiber Index Score™. It does not mean that one food is universally better than another for every eating or activity occasion. That's where Fiber Index Class™ (FI Class™) adds another layer of context. FI Class™ uses FAST™, BALANCED™, and SLOW™ to describe different Fiber Index profiles based on their relative fiber context and the potential for fiber-associated moderation of carbohydrate digestion and absorption.
Different profiles can fit different occasions.
Different foods. Different occasions. Different FITs.
