Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Several studies have shown that regular intake of nuts may improve blood lipids. However, few studies have investigated the effects on blood lipids after a single intake of nuts. The present study was conducted in order to evaluate the acute effects of a single intake of Brazil nuts on blood lipids.

The study was a non-blinded randomized controlled study with 52 participants, 26 participants in both the Brazil nut group and in the control group. Blood tests were taken at baseline and 3h, 6h, 24h, 7d and 14d after ingestion of either 50g Brazil nuts or an isocaloric amount of coconut flakes. We then conducted an unpaired t-test in order to compare changes in blood lipids between the two groups. P-values \< 0.05 were considered statistically significant
