Yes, Brazil nuts can help lower cholesterol levels. They are rich in healthy fats, including monounsaturated and polyunsaturated fats, which can improve cholesterol levels by reducing LDL (bad cholesterol) and increasing HDL (good cholesterol). Additionally, Brazil nuts are high in selenium, an antioxidant that can help prevent oxidative damage and inflammation, contributing to better heart health. Eating Brazil nuts in moderation can be a beneficial addition to a diet aimed at managing cholesterol levels.
