A recently published study in Nutrients aimed to see how walnut consumption affects the lipid profile of consumers.

A systematic review and meta-analysis of randomized controlled trials from 2010 to 2022 were conducted by researchers in order to look at how walnut consumption affects the lipid profile. In total, 13 trials from the US, Europe, and Asia were included in the study. The results showed that walnut consumption was associated with a significant reduction in total cholesterol, low-density lipoprotein (“bad”) cholesterol, and triglycerides. It also showed that walnut consumption was not associated with high-density lipoprotein (“good”) cholesterol.

In conclusion, the systematic review and meta-analysis provide evidence for the health benefits of walnuts on blood lipids. The authors conclude that walnuts may reduce the risk of cardiovascular disease, so they can be successfully added to a dietary pattern to enhance health benefits.
