-
Including sure spices corresponding to rosemary, turmeric, and gingerroot has additionally been proven to dramatically cut back HCAs on account of their highly effective antioxidant properties. These spices include pure compounds that assist block the chemical reactions that result in HCA formation throughout high-heat cooking.

-
Cooking meat at decrease temperatures and flipping it incessantly additionally helps cut back the quantity of HCAs fashioned.
