A study funded by the Almond Board of California explored snacking's effects on mental stress. Researchers at King's College London conducted a clinical trial to measure heart rate variability (HRV), an indicator of the cardiovascular system's response to stress, in participants undertaking a laboratory-controlled mental stress challenge. The researchers noted HRV improvement in study participants who had replaced their typical snacks with almonds, measured over a six-week period.
Findings from the report are summarized here.
