Excessive sugar consumption is a widely-acknowledged problem in the modern Western diet. One of the specific problems often stated is that the quick consumption of highly sugar-laden foods leads to spikes in blood sugar, the corresponding burden placed on the pancreas to produce a sufficient amount of insulin, etc.
But these same warnings on the ills of sugar always give a pass to fruit, and the justification is usually that the fiber in fruit slows down the processing of the sugar in the blood, thereby avoiding the spikes in blood sugar levels.
This is just one example of an article articulating what I've summarized above about blood sugar spikes, fruit, and fiber, but the same has been described in an innumerable number of articles: https://www.johnson.k-state.edu/health-food-safety/agents-articles/should-you-avoid-sugars-in-fruit-and-milk-for-weight-loss.html
In my mind, this then raises the question: can the blood sugar spikes caused by all sugar consumption be avoided by consuming a compensatory amount of fiber?
E.g. can a person mitigate the blood sugar spikes from eating an ice cream or cheesecake by eating Metamucil, or some other such fiber supplement?
An obvious response might be: if it was that simple, everyone would do it, which implies that the short answer is "no" -- but if so, I'd like to learn why it isn't that simple: if blood sugar spikes from sugar in fruit is mitigated by its inherent fiber, why can't blood sugar spikes from added-sugar in human-made food be mitigated by consuming some "compensatory" amount of fiber?
