A University of Liverpool genetic study put a number on what most doctors still ignore: what blood sugar does an hour after you eat may be the strongest dietary signal we have for future dementia risk.

As a medical school professor, I teach fasting glucose. The data say we may be watching the wrong number.

Mendelian randomization across large genetic cohorts:

- Higher post-meal blood sugar spikes = 69% higher Alzheimer's risk
- Signal held after controlling for fasting glucose and HbA1c
- Postprandial hyperglycemia stood out as the key dietary risk factor
- Genetic instruments imply causation, not just correlation

Some researchers call Alzheimer's "Type 3 diabetes." The brain is insulin-sensitive, and chronic glucose spikes drive insulin resistance, mitochondrial damage, and inflammation in neurons.

The fix is unglamorous and free: real food, protein and fiber first, walk after meals, watch the spike.

This news is concerning, as it suggests that these children will have a heightened risk of heart disease, strokes, cancer, kidney disease, and dementia when they reach their 50s and likely will be permanently disabled by 60. It is imperative that parents take proactive measures to mitigate this risk. Enough of these ultra-processed foods and sedentary lifestyles!

Nearly 1 in 3 U.S. teens has prediabetes. New research says a tape measure may catch risks that BMI completely misses.
