: Medications to control an elevated blood cholesterol level should not be thought of as a license to eat and live in an unhealthful manner. It makes little sense to then dismiss the problem with thoughts that a pharmaceutically lowered cholesterol level fixes everything. DEAR DR. BLONZ: I buy raw almonds and bake them in a toaster oven at 250 degrees for about half an hour. Does roasting the almonds cause the oil in the nuts to undergo a change that turns it into saturated fat? : The roasting of nuts does not affect the minerals they contain, and it does not make their oils more saturated.
