Fiber Index Class™ — The Potential

​

Fiber Index Class™ (FI Class™) is the interpretation layer that places a food's Fiber Index profile into one of three easy-to-understand classes:

​

• FAST™ — lower potential for fiber-associated moderation of carbohydrate digestion and absorption

• BALANCED™ — intermediate potential for fiber-associated moderation of carbohydrate digestion and absorption

• SLOW™ — higher potential for fiber-associated moderation of carbohydrate digestion and absorption

​

The classes reflect the relative fiber context surrounding available carbohydrate within the Fiber Index Fit™ model. As fiber presence increases relative to available carbohydrate, Fiber Index Fit™ moves from FAST to BALANCED to SLOW, reflecting increasing potential for fiber-associated moderation.

​

Why “Potential” Matters

​

Dietary fiber can influence carbohydrate digestion and absorption, but foods are complex and individual responses vary.

​

Fiber Index Class™ describes a food's position within the Fiber Index Fit™ model. It does not directly measure digestion speed, gastric emptying, glycemic index, or predict an individual's post-meal glucose response.

 

Potential, not prediction.

​

What does “potential moderation” mean?

 

Simply put  "the more fiber present relative to available carbohydrate, the greater the potential for fiber to moderate how those carbohydrates are digested and absorbed".

​

FAST™ = lower potential for fiber moderation
BALANCED™ = intermediate potential for fiber moderation
SLOW™ = higher potential for fiber moderation

​

Why This Matters

 

Nutrition labels tell you how much fiber a food contains. Fiber Index Fit™ asks another question:

How much fiber is present in the context of the food that contains it? FI Class™ translates that context into a simple FAST™, BALANCED™, or SLOW™ profile that makes differences between foods easier to understand.

​

What's the right FIT for the occasion?

 

FAST™ isn't bad. SLOW™ isn't always better.

​

Sometimes carbohydrate availability is the priority. At other times, a stronger fiber context may be the priority. And sometimes, the right fit is somewhere in between. That's where Fiber Index Fit™ moves beyond classification and toward real-world food choice.

​

Different foods. Different priorities. Different occasions. Different FITs.
