Postprandial insulin response refers to the increase in insulin levels that occurs after eating. This response is an important aspect of glucose metabolism, as insulin helps to regulate blood sugar levels and prevent hyperglycemia (high blood sugar). Insulin signals cells to take up glucose from the blood, which is then used for energy or stored for later use.
However, the postprandial insulin response can be excessive for some individuals, leading to insulin resistance. Insulin resistance occurs when the body’s cells become less responsive to insulin, resulting in higher levels of insulin needed to regulate blood sugar levels. Over time, this can lead to an increased risk of developing conditions such as type 2 diabetes, cardiovascular disease, non-alcoholic fatty liver disease and, surprisingly, Alzheimer’s disease.
