Showing posts with the label fibre

Diamond in the Roughage

In the world of keto, "Fibre" is the magic eraser. It is the variable in the equation that allows us to look at a label, do some quick math ( Total Carbs minus Fibre ), and decide if a food is safe. This "Net Carb" math relies on a simple biological premise: Fibre is indigestible. It passes through us without turning into glucose, so it doesn't count. But in my day job as a Manager of Quality and Compliance, I know that broad definitions are where the errors hide. If you eat a cup of broccoli, you are eating fibre. If you eat a "Keto-Certified" candy bar, you are also eating "fibre." But your body reacts to those two things very differently. One is a nutrient-dense whole food; the other is often an industrial chemistry experiment designed to hack the nutrition label. Here is the "Red Flag" audit on fibre, and why I don't trust every gram I see. Part 1: The "Good Guys" (Whole Food Fiber) When fibre comes wrapped in the ...

Fibre Optics

Quick grammatical note: you'll notice my use of the word "fibre" over "fiber". My preference is simply for the King's English. Please bear with me. In my day job as a Manager of Program Quality, I deal with data. I know that if you feed bad data into a system, you get bad results. In the tech world, we call it "Garbage In, Garbage Out." In the world of keto, there is a piece of data that is corrupted, compressed, and often completely misleading. It’s the number bolded on the front of every protein bar and low-carb snack: "Net Carbs." The formula seems simple: Total Carbs minus Fibre minus Sugar Alcohols = Net Carbs. It’s a great algorithm. The logic is sound: fibre is indigestible, so it doesn't count as fuel. It passes through the system without "uploading" glucose to your bloodstream. But just like a fibre optic cable, the quality of the signal matters. And I’ve learned that when it comes to food labels, not all fibre is ...
