Seen a different rating somewhere else?+
Usually it's a portion difference, not a disagreement. This page scores tomato at a serving of 1 small tomato (65g); at just over 1/2 medium tomato (75 g) or more it belongs in the high band. A source quoting the larger serve will call it high, and one quoting the smaller will call it low — the same food, measured at two different amounts.
