ADVERTISEMENTRaw vs roasted nutsPreferably, eat your nuts raw, as this is generally considered the healthier option. However, roasted nuts have pros as well. Roasting also results in water evaporation, meaning roasted nuts are slightly higher in calories and fat per gram. Added Oils & Salt: Many commercially roasted nuts are cooked in heavy oils and are heavily salted. Eat roasted: Almonds and cashews – high monounsaturated nuts – digest easier when roasted.
