Marinating your meat in beer before grilling can reduce potentially harmful substances from forming, a new study has found.
Researchers from the University of Porto in Portugal found black ale works the best in protecting meat from developing polycyclic aromatic hydrocarbons (PAHs). PAHs can form on meat when it's cooked at a very high heat, such as on a backyard barbecue.
PAHs are also found in cigarette smoke and car exhaust, and have been associated with cancers in lab animals. Although it's unclear if PAHs cause cancer in humans, other studies have linked the consumption of grilled meats with a high incidence of colorectal cancer.
The researchers marinated samples of pork in black ale, non-alcoholic Pilsner and a Pilsner for four hours before cooking them to well done on a charcoal grill.
The research was published in the Journal of Agricultural and Food Chemistry.
