Why Corn is a Carb Culprit
Corn kernels contain about 19g net carbs per 100g, spiking blood sugar faster than table sugar according to USDA data from 2022, making it a no-go for keto, low-carb, or diabetic diets followed by over 15 million Americans as of 2025.
Since the Atkins diet boom in the early 2000s, demand for corn alternatives has surged 300%, per Google Trends analysis through May 2026, driving innovation in veggie swaps that retain corn's hallmark corn-syrup-like sweetness without the glycemic load.
