Research suggests that eating rye bread may do an even better job than wheat bread at keeping stomachs from growling later in the day.

In a study, people who ate rye bread with breakfast were less hungry before and after lunch compared with people who ate wheat. Rye's super-high fiber content probably has something to do with it. But researchers suspect that rye may also produce a lower insulin response than wheat bread (this would help with hunger) and that rye may have a unique fiber composition that keeps people feeling full longer.

Of all the rye breads tested, rye-bran bread had the best effect on hunger. Makes sense, since it also has the highest fiber content of the breads.
