For years many of us, myself included, have shaken our heads in exasperation as you braai okes interspersed your intellectual conversation with occasional, almost ritual, movements of pouring some beer over the chops and steak as they gently charred to a frazzle. "What are you doing? What a waste of good beer?" "Ach no man, I'm just adding a little bit of flavour to the steak." Well it turns out that as suspected you weren't adding any bloody flavour to the meat but unwittingly you were decreasing the carcinogenic effects of cooking over open flames. It would of course be better if you did it before starting to braai but it is a step in the right direction. It seems that if you are frying a steak and mindful of your health, then marinate it in either beer or red wine. So say food scientists who measured amounts of a family of carcinogens found in fried steaks after steeping them in booze. Cooking food increases levels of cancer-causing compounds called heterocyclic amines (HAs). Fried and grilled meat are particularly high in these compounds, because fiery temperatures convert the sugars and amino acids in muscle tissue into HAs. Various substances can reduce HA content: an olive oil, lemon juice and garlic marinade cut HAs in grilled chicken by 90 per cent, while red wine reduced HAs in fried chicken. Now Isabel Ferreira and colleagues at the University of Porto in Portugal have looked at the effects of beer and red wine marinades on fried steak. Six hours of marinating in beer or red wine slashed levels of two types of HA by up to 90 per cent compared with unmarinated steak. For a third type of HA, beer was more efficient at reducing its content than wine, cutting levels significantly in 4 hours, while wine took 6. Tasters also preferred the smell, taste and appearance of beer-marinated steak. So now you can baffle them with science when they laugh at your little quirk.
