The use of sesame oil in cooking and as a health supplement has become increasingly popular due to its nutritional benefits and distinct flavor. However, like any other edible oil, sesame oil does have a shelf life and can become rancid if not stored properly or if used beyond its expiration date. The question of what happens if you eat expired sesame oil is a critical one, especially considering the potential health implications. This article aims to provide a comprehensive overview of the effects of consuming expired sesame oil, the reasons behind its expiration, and how to properly store and use sesame oil to maximize its benefits while minimizing risks.
Introduction to Sesame Oil
Sesame oil is extracted from sesame seeds and is known for its high nutritional value, including being a good source of vitamin E, antioxidants, and healthy fats.
