A national study of 2,051 U.S. adults found that food insecurity in later life was associated with 85% higher odds of screening positive for probable dementia. The observational research does not establish cause and effect, but highlights how affordability, nutrition and financial stress may intersect with brain health as people age.

A 12-year MRI study of 1,647 adults suggests that eating more closely in line with the MIND diet was associated with slower grey-matter shrinkage. Higher scores, driven especially by berries and poultry, were linked to brain changes equivalent to roughly 2½ fewer years of ageing. The observational research cannot prove diet protects memory or prevents dementia.
Health
A long-running study of 5,370 adults over 50 found that people who ate the most ultra-processed foods had higher risks of dementia and cognitive impairment, while those eating more whole foods had lower dementia risk. The findings show an association, not proof of cause, but point to sugary drinks and processed meats as practical places to start making changes.

A Harvard-led study of 131,821 people followed for up to 43 years found that higher caffeinated coffee consumption was associated with an 18% lower relative risk of dementia. The strongest associations appeared at two to three daily cups, while decaf showed no significant link. Researchers stress that the observational findings do not prove coffee prevents dementia.

Harvard Health says creatine does not build muscle on its own; its general recommendation is 3 to 5 grams a day of creatine monohydrate for people who already train.

Harvard Health says most people load protein into dinner; spreading it across meals, with plants carrying more of the load, is better for muscle and heart health.

A Tufts University analysis of 47,999 U.S. adults found that higher ultra-processed food consumption was associated with less-favourable cardiometabolic measures, certain health conditions and higher all-cause mortality risk. Adjusting for overall diet quality weakened, but did not eliminate, those associations. The observational study does not prove causation, but raises questions about factors beyond familiar nutrition-label numbers.

Low vitamin D levels have been linked with changes in mood, fatigue, and low energy, raising concerns about hidden deficiency effects in everyday health.
