Rancidity can be increased by increasing the temperature and the amount of air and moisture. It can be prevented by storing foods within a short time. Restricting the air and moisture can also prevent rancidity.

Refrigerate all oils, including olive oil. Remove oil from the refrigerator ten to twenty minutes before use. This will allow it time to liquidify. If you're busy, just scoop it out with a soft knife. Think about this: You wouldn't leave your butter out, because you know it'd turn rancid. Same concept for your oil. My Italian grandmother taught me this as a child and she had practiced her entire life. How she knew this long before science discovered the danger of free radicals (e.g. when oil turns rancid) must be related to time-tested health issues. Also be careful about eating products made with oil that has been stored at room temperature. Some scientists have found a strong link between Free Radicals and cancer to aging. So if you want to live to a long date, refrigerate.

What is a major cause of rancidity of lipids in foods is exposure to?

Rancidity is caused by hydrolysis and oxidation. Heat, moisture and exposure to light will increase these chemical reactions and thus increase the likelikhood of the onset of rancidity.

How do you overcome rancidity?

Rancidity is not reversible, so it cannot be overcome. It might be possible to slow it down or prevent it with the use of antioxidants or using oxygen depleters. Cooler or freezer storage may slow the reaction, too.
