DID YOU KNOW that there were three recent studies regarding cognition and memory that may surprise and/or delight you?

Higher levels of vitamin D in the blood during middle age may be tied to lower amounts of tau protein in the brain years later, according to a study in Neurology. Tau is a key biomarker associated with dementia.

A study from JAMA Network Open found that higher meat consumption was associated with better cognitive trajectories and lower dementia risk among individuals with APOE34/44 genotypes. The expected cognitive disadvantage among individuals with APOE34/44 genotypes was not observed at high meat consumption.

According to the authors of a study from The Journal of Human Nutrition and Dietetics, one egg per day may be necessary to maintain healthy cognition function in the elderly, which may be an effective food therapy to alleviate cognitive decline.

DID YOU KNOW that a study from Alzheimer's & Dementia found that higher vitamin B12 status in mid-to-late life was associated with slower declines in memory, executive function, and language compared to lower status in patients without baseline dementia? Additionally, the associations for executive function and language persisted regardless of folate status.

In patients with diabetic peripheral neuropathy and low serum vitamin B-12 levels, 16 weeks of daily supplementation with at least 1000 mcg of vitamin B-12 improved neuropathic symptoms, according to a study from The Journal of Nutrition.

DID YOU KNOW that late night eating and chronic stress are a bad combination?

According to a study presented at Digestive Disease Week 2026, participants who reported having high stress in addition to late-night eating habits had the highest prevalence of abnormal bowel habits (39.3%) compared to those with a low-stress/normal eating baseline. The high stress/poor diet high-risk group also had significant reductions in gut microbial diversity compared with healthy controls.

While stress alone degrades gut function, the combination with late-night eating creates a "double hit’"associated with pronounced bowel dysfunction and gut dysbiosis.
