(New York Times) — Despite a dirge of grim health statistics, an epidemic of diabetes and heart disease and campaigns by heath agencies and organizations, the Delta diet, a heavenly smorgasbord of things fried, salted and boiled with pork, has persisted. It has persisted because it tastes good, but also because it has been passed down through generations and sustained through such cultural mainstays as the church fellowship dinner. But if the church helped get everybody into this mess, it may be the church that helps get everybody out. For over a decade from his pulpit here at Oak Hill Baptist in North Mississippi, the Rev. Michael O. Minor has waged war against obesity and bad health. In the Delta this may seem akin to waging war against humidity, but Mr. Minor has the air of the salesman he once was, and the animated persistence to match.
