Sweet almond oil contains high concentrations of monounsaturated fatty acids, or MUFAs. These unsaturated fats are linked to cardiovascular disease prevention. An article published in "The Journal of Nutrition" in April 2002 noted that studies done on MUFAs show that both whole almonds and almond oil effectively reduce harmful low-density lipoprotein cholesterol, LDL, and increase protective high-density lipoprotein cholesterol, or HDL, which may reduce cardiovascular risk.
