When it comes to using oils, be sure that you always purchase those that are cold-pressed. This will ensure that the oils have retained all of their nutrients, flavor, and aroma. Cold pressed oils are produced at very low temperatures, even lower than 120 degrees Fahrenheit. When oils are exposed to high heat, many of the beneficial nutrients are destroyed and the oil can even become rancid. Olive, peanut, and sunflower oil are among the oils that can be obtained through cold pressing. Cold pressed oils can cost a little bit more than conventional oils, but it’s well worth it for the difference in taste and nutrients!
