Surprising Findings
The association between nut consumption and all-cause mortality was non-linear (Pnon-linearity<0.001), suggesting diminishing returns at very high intake levels.
While more nuts generally help, the biggest drop in mortality risk happens at moderate intake — eating massive amounts may not add much extra benefit.
Practical Takeaways
Add one 28g serving (about a handful) of unsalted nuts to your diet each week to reduce heart disease risk.
