A Nature Medicine study found that fiber only blunts blood-sugar spikes in people with good insulin sensitivity. For those with insulin resistance or type 2 diabetes, fiber has almost no effect, so an apple won't protect them the way it does for others.
Are you fiber resistant? Now, we've all heard that advice: eat fiber to blunt your blood sugar spikes. But brand new research published in Nature Medicine shows it's not that simple. In people who are insulin sensitive and metabolically healthy, fiber does work to blunt blood sugar. Eat it before carbs and you'll see a smaller sugar spike. But in those with insulin resistance or type 2 diabetes, that benefit is diminished. So what does this mean? Simply put, the fiber in fruits is going to be less protective if you have insulin resistance already. So an apple might not be your sugar's best friend. But the good news is there are many other tricks that will lower blood sugar. Now let me tell you about them.
