Popular Tyrosine Supplement Linked to Shorter Lifespan in Men, New Research Finds

Research published on February 4, 2026, in Neurology Open Access — a journal of the American Academy of Neurology — found that women who closely followed a Mediterranean dietary pattern had significantly lower rates of stroke over more than two decades of follow-up. The study enrolled 105,614 women with no prior stroke history and an average age of 53. Participants completed detailed dietary questionnaires, and researchers scored adherence to the Mediterranean diet on a scale of zero to nine.

Over an average follow-up of 21 years, researchers recorded 4,083 stroke events: 3,358 ischemic strokes and 725 hemorrhagic strokes. Women with the highest Mediterranean diet scores were 18% less likely to experience any stroke compared to those with the lowest scores, with a 16% lower risk of ischemic stroke and a 25% lower risk of hemorrhagic stroke — a particularly striking finding, as hemorrhagic strokes are less frequently studied in dietary research.

The diet's most protective elements appeared to be higher consumption of vegetables, fruits, legumes, fish, and olive oil, combined with reduced intake of red meat and saturated fats. Researchers note that the study identifies a statistical association rather than direct causation, and acknowledge that reliance on self-reported dietary data is a limitation. Nevertheless, the large sample size and lengthy follow-up period provide a substantial evidence base for the relationship between Mediterranean eating patterns and stroke risk in women.

Research from Aarhus University, published in The Journal of Nutrition and widely reported in February 2026, found that middle-aged Swedish adults who closely followed the 2023 Nordic Nutrition Recommendations had a 23% lower risk of dying from any cause compared to those who did not. The analysis drew on data from more than 76,000 participants enrolled in the Swedish Mammography Cohort and the Cohort of Swedish Men, who have reported their dietary habits and lifestyle factors regularly since 1997.

The 2023 Nordic dietary guidelines encourage reducing meat and added sugar intake while increasing consumption of whole grains, legumes, fish, and low-fat dairy products. Notably, the guidelines were designed with environmental sustainability as a co-equal goal alongside personal health, meaning adherence may benefit both individual wellbeing and the planet. The study also found that closely following the guidelines was associated with significantly lower mortality from cancer and cardiovascular disease specifically.

The 23% reduction in all-cause mortality held firm after controlling for education level, income, and physical activity — suggesting the dietary pattern itself, rather than related lifestyle factors, may be responsible for the benefit. Led by Associate Professor Christina Dahm and PhD student Anne Bak Mørch, the findings position the Nordic dietary framework as a compelling evidence-based alternative to the more globally studied Mediterranean diet, with the added advantage of being culturally adapted to Nordic and Baltic populations.
