Leave it to Italian scientists to come up with this one.
Your cheese habit might have a surprising benefit: Eating a certain Italian variety might protect your heart, new research from the Journal of the American Society of Hypertension suggests.
In the study, people with high blood pressure who ate one ounce of Grana Padanoâa semi-fat hard cheese similar to Parmigiano Reggianoâdaily for two months improved their systolic blood pressure (the top number) by 7 to 8 millimeters of mercury (mm Hg) and their diastolic blood pressure (the bottom number) by 5 to 7 mm Hg.
In comparison, those who ate an imitation, fake-dairy version of the cheese saw no improvement in their blood pressure readings.
Grana Padano contains two compounds called isoleucine-proline-proline (IPP) and valine-proline-proline (VPP), which can relax your blood vessels to lower your BP, says lead study author Giuseppe Crippa, M.D., director of the hypertension unit at Italyâs Guglielmo Saliceto Hospital.
They act similar to blood pressure meds called ACE-inhibitorsâlike Lotensin and Capotenâby stopping the bodyâs production of angiotensin II, an active hormone that constricts blood vessels to increase blood pressure.
The studyâs finding is good news for your heart, but itâs not an excuse to go cheese-crazy, says Dr. Crippa.
All cheese contains fat and saltâand the calories can add up quicklyâso make sure you donât overdo it in your diet. Dr. Crippa recommends subbing in one ounce of Grana Padanoâroughly the size of two diceâfor a serving of dairy youâre already eating each day.
More research needs to be done to determine whether similar cheese, like Parmigiano, has the same benefit, he says.
You should be able to find it in the gourmet cheese section at your local grocery store.
