Maintaining and building strength is one of the most important investments we can make in healthy aging. Muscle mass and strength tend to decline over time, especially as we get older, but this is not something we simply have to accept.

Resistance training can help preserve or build muscle, improve strength and physical function, support bone health, and improve sensitivity and blood-glucose control. When combined with balance-focused activity, regular exercise can also help reduce fall risk.

Muscle is metabolically active: working muscles take up glucose from the bloodstream. Building and using muscle regularly can help the body use insulin more effectively and support healthier blood-sugar management.

The benefits go beyond the gym. Regular physical activity is associated with better brain health and lower risk of several chronic diseases, including dementia and many cancers. The goal is not simply to look fit—it is to stay strong, capable, independent, and metabolically healthy as we age.

Do you agree with this quote? Are we taking too many medicines?

While marketed as healthier alternatives to sugar, there is growing evidence linking sweeteners in food and drinks to diseases such as type 2 diabetes, obesity and cancer.

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.
