A BEEFY BALLIET precedes asumo match inHawaii as wrestlers perform the ritual shiko exercise. Victory in this honored Japanese sport comes when one behemoth topples the other or pushes him out of a 15-foot-diameter circle ringed with dirt-packed rice straw. Competitors bulk up at tables groaning with rice. From sushi to sake to simple fare, the grain dominates the Asian diet, providing at least a fourth of the calories for much of a continent that grows by 55 million people a year.
