Research question: Does regular avocado consumption improve markers of cardiometabolic health among adults?
Key findings: This systematic review identified 10 studies published up to November 2021. Daily avocado consumption reduced total- and LDL-cholesterol in adults with elevated baseline cholesterol levels. There was no between group difference in HDL-cholesterol or triglycerides. Due to study limitations, certainty in the findings was graded as low to very low. Furthermore, consuming avocado, in amounts well above current usual intakes, did not result in unfavourable changes in body weight or composition.
