Overview

• The study enrolled 969 racially and ethnically diverse American adults with elevated waist circumference, randomly assigning them to eat one large Hass avocado daily or maintain their usual diet for 26 weeks.
• Participants in the avocado group saw a 3.20-point increase in their sleep health scores compared with the control group, a statistically significant gain.
• Daily avocado consumption also boosted Healthy Eating Index scores and produced modest reductions in LDL cholesterol and total cholesterol levels.
• Despite these individual improvements, the overall Life’s Essential 8 cardiovascular health score did not change significantly between the avocado and control groups.
• Researchers highlight that tryptophan, folate and magnesium in avocados may support sleep regulation and call for further research to confirm these exploratory findings.
