Quick Summary

Unsalted cashews are packed with healthy fats, protein, and essential minerals like magnesium and copper. Regular, moderate consumption can support heart health by lowering LDL cholesterol and triglycerides. Their fiber and protein content promotes satiety, which aids in weight management and blood sugar control. As a potent source of antioxidants, they also help fight inflammation and cellular damage.
