    Nanoparticles in foods raise safety questions

    It seemed like a small thing when Paul Westerhoff’s 8-year-old son appeared, with his tongue and lips coated bright white.

    The need to feed and eating for pleasure are inextricably linked

    You’ve already had a muffin. And a half. You know you’re full. But there they are, fluffy and delicious, waiting for the passersby in the office. Just thinking about them makes your mouth water.

    In fact, most of them already have. Trans fat —a...
