Wondering if you should cut down on red meat and fat to lower your blood pressure? According to a new study, it could depend on your genes…
A recent study in the Journal of the American Heart Association illustrates the interaction between genetics and diet. The study looked at blood pressure measurements in twins on a higher carb diet compared to a higher saturated fat diet.
For the first six weeks of the study, the participants, who were non-obese twin pairs, ate a higher-carb diet which consisted of 55% carbohydrates, 30% fat, and 15% protein. Blood pressure and other blood markers were measured at the end of the six weeks.
For the second half of the study, the participants switched to a higher-fat diet consisting of 40% carbohydrates, 45% fat, and 15% protein, with the fat mainly being saturated fat from red meat, sausage, bacon, and full-fat dairy.
ACE and blood pressure:
The level of ACE, or angiotensin-converting enzyme, was measured. This enzyme controls blood pressure by constricting blood vessels. ACE inhibitors are a common type of blood pressure medication that works by decreasing or inhibiting the angiotensin-converting enzyme. The ACE gene has a common variant referred to as the ACE deletion/insertion.

Lifehacks:
For those who have high blood pressure and ACE deletion (rs4343 G/G), this study indicates that eating a diet high in bacon, cheeseburgers, steaks, and ice cream may be the problem. Try switching to a low-fat diet and tracking your blood pressure for a few weeks to see if it helps.
