With flatter glucose curves, we reduce the amount of insulin—a hormone released in response to glucose—in our body, and this is beneficial, as too much insulin is one of the main drivers of insulin resistance, type 2 diabetes, and PCOS. With flatter glucose curves, we also naturally flatten our fructose curves—fructose is found alongside glucose in sugary foods—which is also beneficial, as too much fructose increases the likelihood of obesity, heart disease, and nonalcoholic fatty liver disease.
