A Swedish study of healthy older adults suggests that an anti-inflammatory diet rich in leafy greens and sardines may offer added protection against dementia for some seniors, potentially outperforming the Mediterranean diet and highlighting the brain health benefits of mindful eating as people age.
Columbia sleep-nutrition researcher Marie-Pierre St-Onge explains that a Mediterranean-style, fiber-rich diet consumed across the day—favoring fruits, vegetables, nuts, whole grains, lean proteins, and minimizing refined sugars—supports better sleep by providing sleep-regulating nutrients, stabilizing blood sugar, and boosting melatonin. Large studies link this eating pattern to less insomnia and longer, more efficient sleep. In her own routine, she emphasizes three-hour-gap between dinner and sleep, a breakfast of high-fiber cereal with banana, lunch featuring sourdough bread with yogurt and fruit, and dinners with fish, legumes, and vegetables, plus dim lighting before bed to cue melatonin and a consistent sleep schedule.
A longitudinal study of 3,296 English adults aged 50–90 finds that higher adherence to a Mediterranean diet is linked to greater positive psychological well-being across autonomy, self-realization, pleasure, and purpose, independent of depressive symptoms or socio-economic status. During the COVID-19 lockdowns, those with strong Mediterranean-diet adherence experienced a smaller decline in well-being, suggesting the diet acts as a mental-health buffer in times of crisis. Possible mechanisms include anti-inflammatory components (polyphenols, omega-3, fiber) that support gut-brain health and neuroplasticity. The researchers advocate for nutritional psychiatry and public policies that promote Mediterranean-style eating to protect mental well-being in aging populations.
Dr. Christina S. Reuss, a cardiologist, advocates adding omega-3 fatty acids for heart health within a Mediterranean-style, food-first approach and uses supplements only when diet isn’t enough. She explains the three omega-3 types (ALA, EPA, DHA), cites fatty fish as a top source, and lists plant options like chia, flax, and nuts. For supplements, she recommends third-party testing, small-month purchases, and sustainable formulations, while noting algae-based options for those with allergies and cautioning that no single nutrient guarantees heart protection—vegetables should fill most of the plate.
Three new studies suggest potential stroke-prevention strategies: a Mediterranean-style diet may lower risk of ischemic and hemorrhagic stroke in women; the shingles vaccine was associated with fewer major adverse cardiac events in people with ASCVD in an observational study (not yet peer-reviewed, so causality isn’t established); and the oral anticoagulant asundexian may reduce secondary ischemic stroke risk in patients who’ve had a prior stroke or high‑risk TIA by inhibiting factor XIa. Stroke is a leading cause of death, with many events potentially preventable through lifestyle and medical interventions.
A panel of health experts says seniors don’t need drastic changes—focus on practical nutrition (fiber-rich foods, at least ~20g protein per meal, vitamin D sources), adequate hydration (about 48 ounces daily), and regular, moderate exercise (~150 minutes per week) tailored to ability. Emphasize a whole, plant-based Mediterranean-style pattern, social well-being, and proactive cardiovascular risk screening to support overall health and independence as we age.
A new review in Trends in Endocrinology & Metabolism suggests fat quality—not total fat intake—may affect type 2 diabetes risk. Palmitic acid, a saturated fat common in meats, dairy and palm oil, can impair insulin action and promote inflammation, while oleic acid found in olive oil may help preserve insulin sensitivity. Diets high in unsaturated fats and patterns like the Mediterranean diet are linked to lower diabetes risk, though much evidence comes from lab and observational studies; more human trials are needed. Practical guidance: replace some saturated fats with heart-healthy fats (olive oil, nuts, seeds) and maintain a healthy lifestyle to reduce diabetes risk.
Stanford epigenetics researcher Dr. Lucia Aronica highlights her mother Livia’s five rules for a long, happy life: eat slowly and with joy using Mediterranean foods; move naturally rather than just in the gym; cultivate close relationships and community; wake up each day with a sense of purpose; and let everyday pleasures guide you. Supported by research on epigenetics, social ties, and positive emotions, true longevity blends biology with psychology and social well-being rather than chasing biomarkers.
A new review from the University of Barcelona finds that palmitic acid (a saturated fat) impairs insulin sensitivity and promotes inflammation, while oleic acid (a monounsaturated fat common in olive oil) improves insulin signaling and fat handling, suggesting fat quality matters more than total fat intake and helping explain the diabetes-protective associations of Mediterranean diets; more research is needed to resolve conflicting epidemiological results and consider fat source and processing.
Dr. Ramesh Kinha outlines five nutrition-based strategies to protect thyroid health ahead of World Thyroid Day (May 25, 2026): follow a Mediterranean (and Paleo-style unprocessed) diet rich in fruits, vegetables, whole grains, healthy fats and lean proteins while limiting large amounts of raw cruciferous vegetables; ensure iodine intake through iodised salt and foods like seaweed, dairy, seafood and eggs with caution for autoimmune thyroid disease; include selenium-rich foods (tuna, eggs, Brazil nuts, legumes, sardines, oats) in moderation to protect the thyroid from oxidative stress; optimize zinc intake (pumpkin seeds, oysters, nuts, lentils) with moderation; boost vitamins D and B12 and minerals iron and magnesium from sunlight, animal products and plant foods, pairing citrus with iron to improve absorption. Also avoid ultra-processed foods; for hyperthyroidism, moderate iodine, caffeine, soy and gluten as advised; combine good nutrition with regular exercise, sufficient sleep and stress management for better thyroid health.
Experts say that in your 40s it’s wise to adopt a plant-forward, minimally processed diet rich in nuts, seeds, legumes, and adequate protein, while prioritizing whole foods over smoothies. Emphasizing patterns like the Mediterranean, DASH, or MIND, and maintaining a healthy weight with regular movement and limited alcohol, could significantly extend lifespan—roughly a decade for many people.
A USC-led study suggests that closer adherence to a Mediterranean-style diet raises mitochondrial microproteins humanin and SHMOOSE, which are linked to protection against aging-related diseases. The research found higher diet adherence correlated with increased levels of these proteins and lower oxidative stress, with olive oil, fish, and legumes connected to higher humanin and olive oil plus lower refined carbs linked to higher SHMOOSE. The work points to mitochondria-centered biomarkers and a potential precision-nutrition pathway, but is observational, so causality remains to be established.
Cardiologists say the Mediterranean diet—centered on olive oil, vegetables, fish, legumes, and minimally processed foods—offers the strongest, sustainable path to longevity by reducing cardiovascular risk (up to 30%), supporting brain health, reducing inflammation, and promoting healthy weight.
Observational studies suggest enduring dietary patterns may influence Parkinson’s disease risk, age at onset and possibly symptom severity. Doctors highlight Mediterranean and MIND diets—rich in antioxidants and anti-inflammatory nutrients—as potentially protective and linked to later onset, while flavonoid-rich foods, coffee, fatty fish, fiber and fermented foods may support brain health. Conversely, dairy (especially milk), ultraprocessed foods and certain dietary pesticide exposures are associated with higher risk in some studies. Experts caution these are associations, not proven causes, and diet is one lever among several (exercise, sleep, gut health) in shaping Parkinson’s outcomes.
A study of 2,192 Australian adults found that every 10% increase in calories from ultra-processed foods is linked to a small drop in attention and a higher dementia risk, with effects persisting even for those following a Mediterranean-style diet; causation isn't proven, but the findings add to concerns about ultra-processed foods and cognitive health.
