“Can food actually build ‘cognitive reserve,’ or is that just genetics?”
Yes—nutritional patterning can augment cognitive reserve, the brain’s buffer against decline. Diets rich in polyphenols (berries, cocoa), lutein/zeaxanthin (leafies), and DHA support synaptogenesis, myelination maintenance, and neurovascular coupling, all of which underpin reserve alongside education and activity.

“Thyroid issues—do iodine and selenium matter for brain energy?”
They do. Iodine enables thyroid hormone synthesis; selenium drives deiodinase enzymes and antioxidant defense in the brain. Aim for steady, not excessive intake.
Sage (cholinesterase modulation), rosemary (carnosic acid antioxidant), and saffron (crocin/crocetin) show promising neurocognitive signals in small trials.

“Canned fish vs. fresh: same brain benefits? Microplastics?”
For DHA/EPA, canned salmon/sardines/mackerel are equivalent hits and often lower in mercury. Microplastic exposure is still being quantified; current risk-benefit favors fish for seniors.

“Salt, sleep, and the glymphatic system—how do they interact with food?”
High sodium can raise nighttime blood pressure, potentially impairing glymphatic clearance (the brain’s wastewash during deep sleep). Evening meals should be lighter, lower-sodium, higher-fiber.
🌙 Evening Rule
🍽️ Plate Build
🧠 Why It Helps
Low sodium
Steam veg + beans + EVOO
Vascular calm → better clearance
Early dinner
3–4 hrs pre-bed
Supports slow-wave sleep
No sugar spikes
Whole grains, not desserts
Reduces arousal, preserves SWS
“Protein ‘per meal’—does leucine timing matter for aging brains?”
Yes. 25–30 g protein with 2–3 g leucine per meal supports muscle (mobility ↔ cognition) and neurotransmitter availability.

🎯 Protein
🌱 Leucine Sources
🙂 Example
Breakfast
25–30 g

Lunch

Dinner

Fish, tofu/tempeh
Salmon + quinoa
“I’m on a SNAP budget—what’s the most cost-efficient brain cart?”
“Copper, iron, and brain aging—should I rethink red meat?”
Excess heme iron may accelerate oxidative stress in susceptible brains. Keep red meat <4×/week, focus on beans, leafy greens + vitamin C to optimize non-heme iron without overload.

⚠️ Risk
✅ Smarter Route
Heme iron (red meat)
Oxidative burden
Legumes + citrus for absorption

“AGEs from high-heat cooking—do they matter for cognition?”
Advanced glycation end products (AGEs) rise with charring/frying and correlate with inflammation.

“Frozen vs. fresh produce—will my brain notice?”
Your neurons care about nutrient density, not the freezer stigma. Frozen produce is often flash-frozen at peak and preserves vitamin C and carotenoids well.

“Fiber and short-chain fatty acids—why do they matter to memory?”
Fermentable fibers feed gut microbes that produce SCFAs (butyrate), which influence neuroinflammation and blood–brain barrier function.
A few matter: metformin ↔ B12 absorption, PPIs ↔ magnesium/B12, statins ↔ CoQ10 (symptoms, not cognition per se). Food-first remains safe; lab-check and supplement only if low.
