WASHINGTON - Food hijacked Dr. David Kessler's brain.
Not apples or carrots. The scientist who once led the government's attack on addictive(使人上瘾的) cigarettes can't wander through part of San Francisco without craving a local shop's chocolate-covered pretzels(一种脆饼干). Stop at one cookie? Rarely.
It's not an addiction but it's similar, and he's far from alone. Kessler's research suggests millions share what he calls "conditioned hypereating" — a willpower-sapping(削弱意志力的) drive to eat high-fat, high-sugar foods even when they're not hungry.
