Grilling meat gives it great flavor. This taste, though, comes at a price, since the process creates molecules called polycyclic aromatic hydrocarbons(PAHs)which【C1】______DNA and thus increase the eater’s chances of developing colon cancer. For those who think barbecues one of summer’s great【C2】______, that is a shame. But a group of researchers led by Isabel Ferreira of the University of Porto, in Portugal, think they have found a way around the problem. When barbecuing meat, they suggest, you should add beer.
This【C3】______advice was the result of some serious【C4】______, as Dr. Ferreira explains in a paper in the Journal of Agricultural and Food Chemistry. The PAHs created by grilling form from molecules called free radicals which, in turn,【C5】______from fat and protein in the intense heat of this type of cooking. One way of stopping PAH -formation, then, might be to apply chemicals called antioxidants that mop up free radicals. And beer is rich in these, in the shape of melanoidins, which form when【C6】______is roasted. So Dr. Ferreira and her colleagues prepared some beer marinades, bought some steaks and headed for the griddle.
One of their marinades was based on Pilsner, a(n) 【C7】______lager. A second was based on a black beer(type unstated). Since black beers have more melanoidins than light beers—as the name【C8】______, they give it color—Dr. Ferreira’s hypothesis was that steaks steeped in the black-beer marinade would form fewer PAHs than those steeped in the light-beer marinade, which would, in turn, form fewer than control steaks left unmarinated.
And so it proved. When cooked, unmarinated steaks had a(n) 【C9】______of 21 nanograms(billionths of a gram)of PAHs per gram of grilled meat. Those marinated in Pilsner averaged 18 nanograms. Those marinated in black beer averaged only 10 nanograms,【C10】______and healthy too, then. Just what the doctor ordered.
A)average B)approximately C)barley D)damage
E)delights F)distinguish G)experiments H)flavor
I)form J)pale K)suggests L)tasty
M)typical N)ultimate O)welcome
【C9】
