Harmful unstable molecules created when food is cooked at high temperatures.
Unstable molecules generated during high-temperature cooking, particularly when oils are heated or foods are charred. These reactive compounds can damage cells and contribute to oxidative stress in the body.
Free radicals are molecules with unpaired electrons that are produced as a natural consequence of high-temperature cooking processes. When oils are heated, fats are charred, or proteins are browned at high heat, free radicals form through various chemical reactions. These unstable molecules can damage healthy cells by stealing electrons, initiating a chain reaction of cellular damage. The body produces antioxidants to neutralize free radicals, but excessive production from cooking can overwhelm these natural defenses. Different cooking methods produce varying amounts of free radicals—grilling and frying generate more than steaming or boiling.
Produced during cooking processes and can contribute to cellular oxidative stress and inflammation if consumed in excess.
Use lower cooking temperatures when possible, and avoid charring or burning foods. Pair high-temperature cooked foods with antioxidant-rich vegetables and fruits. Marinate foods before grilling, as this reduces free radical formation by up to 90%.
Controlling cooking temperature and methods while consuming antioxidants helps minimize harmful free radical exposure.
