Higher tyrosine levels linked to shorter lifespan in major UK Biobank analysis

Researchers analyzed over 272,000 UK Biobank participants and used Mendelian randomization to investigate whether circulating phenylalanine and tyrosine influence lifespan. Genetically predicted higher tyrosine levels were linked to shorter lifespan, particularly in men, while phenylalanine showed no independent effect after adjustment.

Combining healthy lifestyle and GLP-1 therapy reduces heart risks in diabetes

Individuals living with type 2 diabetes (T2D) had a significantly lower risk of poor cardiovascular health when they used a GLP-1 receptor agonist (GLP-1 RA) in combination with adhering to healthy lifestyle habits, according to a new study led by researchers at Harvard T.H.

Both beverages were associated with leukocyte reductions and organ-related biochemical shifts, with sugar-sweetened cola more strongly linked to renal markers and diet cola to elevated liver enzymes.
