Alzheimer's disease presents a significant health challenge, increasingly affected by age. Studies have illustrated staggering statistics on the likelihood of developing the disease based on age brackets:

• 10% of 65-year-olds are affected.
• 25% of 75-year-olds suffer from the disease.
• 50% of 85-year-olds can develop dementia or Alzheimer's.

These numbers emphasize the growing concern of cognitive decline among the elderly and underline a pressing issue lacking effective pharmacological interventions.

Despite over two billion dollars invested in research to produce medications to combat Alzheimer's, it remains an elusive target. Unfortunately, efforts so far have ended in disappointment, leading scientists to delve deeper into understanding the disease's roots.

A narrowed understanding of Alzheimer's shows that poor metabolic health, prompted chiefly by insulin resistance, drives a cascade of health issues culminating in this form of dementia. Elevated insulin levels and high sugar intake exacerbate conditions favorable to the onset of Alzheimer's, making dietary factors critical contributors. It's noteworthy that signs of Alzheimer’s can be present _decades earlier_ than its symptomatic onset.

Understanding the interaction between one's diet and metabolic changes provides an opportunity for altering disease trajectories, particularly concerning Alzheimer's. By making informed lifestyle and dietary choices, it becomes feasible to positively influence brain health and potentially stave off cognitive decline.

The sooner we acknowledge the role of diet on cognitive health, the more effective our interventions can be.
