While many anecdotal reports exist, there are no large clinical
trials to confirm the reports. Whole grains are an excellent source for
nutrients and minerals. However, it is unlikely they can lower blood pressure
on their own. The current guidelines recommend that adults eat about 85 grams
of whole grains every day or about 2-3 slices of whole wheat bread. In reality,
the majority of population eats less than 25 grams a day of whole grains. Whole
grains have a terrible taste- after one bite most people order a pizza or a
burger.
