There's new evidence that cruciferous vegetables blunt spikes in blood sugar levels, which could be particularly important for those with type 2 diabetes or are at risk of developing the condition. “We found that, when participants consumed the cruciferous vegetables, they had less variable blood sugar levels compared to when they consumed the root and squash vegetables. We also noted that these participants had a smaller spike in sugar levels after the meals. "A central goal of blood sugar control, particularly for people with diabetes, is to smooth out spikes and reduce variability in blood sugar levels throughout the day," she added. "Even more concerning is that cruciferous vegetables are among the least consumed vegetables," said nutritionist Lauren Blekkenhorst, a researcher at ECU.
