All types of cooking oils can be bad for your health if you eat too many foods cooked with cooking oils.
But Canola Oil is actually one of the healthiest cooking oils to cook with due to the high content of monounsaturated fats that Canola Oil contains.
The monounsaturated fats contained in Canola Oil can help to lower Cholesterol levels and prevent heart disease when eaten in moderation.
So if you need to cook foods using cooking oils you should use Canola Oil or even Olive Oil for the healthiest results.
