| Cardiovascular Health, Longevity & Mortality

Comment: The traditional cardiological focus on lowering LDL-C in the elderly rests on a foundation of biochemical plausibility that is increasingly dismantled by actual survival data. This systematic review identified a critical physiological disconnect: for those over age 60, high LDL-C is not a mortality stressor but is actually associated with a longer lifespan. In […]

This one is particularly interesting as it breaks it down by age, showing that as we get older, higher cholesterol becomes more protective.

Comment: Although this doesn’t negate the potential of increased risk of atrial fibrillation seen in other studies, a lower rate of death seems more important. Summary: Clinical Bottom Line This large cohort study shows a modest association between habitual fish oil use and a lower risk of all-cause mortality. However, it is not possible to […]

Comment: Another study showing that animal protein intake does not increase death rates. In fact, this study links higher animal protein intake to a reduced risk of cancer, albeit small. This study was designed specifically to revisit the controversial 2014 Levine findings that suggested a four-fold cancer risk from animal protein. By applying more sophisticated statistical […]
