Memory loss is not the first sign of Alzheimer's disease.

The proteins that drive dementia — amyloid-beta and tau — accumulate in your brain's smell-processing structures years before they reach memory regions. Large studies tracking people for up to 12 years found standardized smell tests predicted dementia risk with real accuracy.

But here's the context: olfactory dysfunction is a risk marker, not a diagnosis. No smell test has been approved to diagnose dementia. And most smell loss — from infections, allergies, medications, COVID-19 — is reversible.

Persistent, unexplained smell loss that isn't linked to illness or allergies? That's a conversation worth having with your doctor. Not panic — a data point.

Early attention leads to early options.

The low-carb vs. low-fat debate? A 200,000-person Harvard study just proved it's the wrong question.

✓ Low-carb whole foods = heart protection
✓ Low-fat whole foods = same heart protection
✗ Low-carb ultra-processed foods = increased heart disease risk
✗ Low-fat ultra-processed foods = same increased risk

The variable that matters: food quality and processing level — NOT macro ratios.

Before your next meal, ask: could I recognize every ingredient? That simple filter beats counting macros every time.
