An Examination of Current Research, the Gut Brain Axis, and Viome’s Proposition

Dementia is a progressive neurological disorder that affects millions of people worldwide. It is characterized by a decline in cognitive abilities, including memory, thinking, and problem-solving skills. While the exact cause of dementia is still unknown, recent research has suggested a potential link between diet and the risk of developing this condition. This article will explore the findings of a study published on Medical News Today[1], which discusses the relationship between diet and dementia and the proposition of Viome, a company that offers personalized nutrition recommendations based on an individual’s gut microbiome[2].

Insulin Resistance and Alzheimer’s

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.
