Fruit & Vegetable Carbohydrate Guide

Not all carbohydrates are equal. Understanding which ones your body absorbs — and which feed your gut bacteria instead — is essential on a low-carbohydrate diet.

Total Carbohydrate

The headline figure on any nutrition label. It includes both the carbohydrates your body absorbs and the fiber it cannot — so on its own, it overstates the metabolic impact of a food.

Net Carbs — The Absorbed Portion

Total carbs minus fiber. This is what actually reaches your bloodstream, raises blood glucose, and triggers an insulin response. On a VLC diet, net carbs is the figure that matters.

Fiber — Food for Your Gut Bacteria

A complex carbohydrate that passes undigested to the colon, where it feeds beneficial gut bacteria. Fiber does not raise blood glucose. A healthy gut microbiome depends on an adequate supply of it.

Very low carbohydrate (VLC) daily targets: under 20g net carbs is ideal for therapeutic benefit; under 50g supports general metabolic health. At 20g, half an apple (≈ 6g net carbs) and one serving of broccoli (≈ 5g net carbs) together already account for more than half the daily allowance.

Net carbs — absorbed, raises blood glucose

Fiber — feeds gut bacteria, not absorbed

Vegetables Ranked by Carbohydrate Content

For a very low carbohydrate diet of under 20g per day, even vegetables need careful attention. Starchy vegetables like potatoes and corn are particularly high and are best avoided entirely on a VLC diet. Below-ground root vegetables tend to be significantly higher in carbohydrates than above-ground leafy and stem vegetables.
