Lately, I’ve been falling over some contents claiming that blood sugar is always stable in healthy people and the glycemic index is none-sense unless you are diabetic. While there are many misconceptions at the moment about what causes chronically dysregulated blood sugar and insulin resistance - i.e. some claiming that carbs are the issue, and we just need to cut carbs out and eat a meat-based (carnivor) or fat-based (keto) diet - it is simply also not true that blood sugar always keeps stable in healthy people. Or actually it is true that for as long as the body is still healthy enough to produce enough insulin to quickly get the glucose out of the blood stream (in contrast to diabetics) the overall blood sugar levels keep stable - but(!!) the more high spikes and following crashes we get from the foods we eat the less healthy we will be in time. So while we at the peak of our health may be able to have overall balanced blood sugar regardless of what we eat on the glycemic index - this doesn’t mean that it down the road is ideal to continue to engage in, if we are to STAY healthy.“There are lots of folks running around with their glucose levels spiking, and they don’t even know it,” said Michael Snyder, PhD, professor and chair of genetics at Stanford and senior author of the study. The spikes are in fact a health problem because high blood sugar levels, especially when prolonged, can contribute to cardiovascular disease risk and a person’s tendencies to develop insulin resistance, which is a common precursor to diabetes, he said.“We saw that some folks who think they’re healthy actually are misregulating glucose — sometimes at the same severity of people with diabetes — and they have no idea,” Snyder said. Furthermore, when we get a blood sugar spike, followed by a crash this is known to affect cortisol which increases hunger - and thus we have the craving cycle.
