Insulin resistance in the brain may link Alzheimer’s and epilepsy

Researchers at the University of São Paulo (USP) in Brazil have succeeded in showing, in an animal model, that the process of insulin resistance in the brain affects both Alzheimer's disease and epilepsy and may be a linking factor between the two diseases.

Blood and urine tests reveal how much ultra-processed food you really eat, study finds

Researchers developed and validated blood and urine metabolite scores that objectively measure ultra-processed food (UPF) intake in adults. These biomarker profiles accurately distinguished between high- and low-UPF diets and may transform nutrition research and public health monitoring.

Eating garlic, berries, and tea may support younger, healthier cells

Higher intake of methyl adaptogen foods, such as turmeric, green tea, and berries, was associated with reduced epigenetic age in middle-aged men, according to a secondary analysis of the MDLS trial. These findings support the potential role of specific dietary polyphenols in modulating biological aging, though further research in larger and more diverse populations is needed.
