Research has suggested that ALA may help heart arrhythmias, and a 2006 Spanish study suggested that walnuts were as effective as olive oil at reducing inflammation and oxidation in the arteries after eating a fatty meal. The authors of this study, funded in part by the California Walnut Commission, recommended eating around eight walnuts a day to achieve similar benefits.
