One of three U.S. adults
has hypertension and 78.6 million are clinically obese, a risk factor for the
development of hypertension. Because of the strain that it puts on blood vessel
walls, HBP is one of the most common risk factors of stroke and an accelerator
of multiple forms of heart disease, especially when paired with excess body weight.
The researchers analyzed
protein intakes of healthy participants from the Framingham Offspring Study and
followed them for development of high blood pressure over an 11-year period.
They found that adults who consumed more protein, whether from animal or plant
sources, had statistically significantly lower systolic blood pressure and
diastolic blood pressure levels after four years of follow-up. In general,
these beneficial effects were evident for both overweight (BMI ≥25 kg/m2) and
normal weight (BMI <25 40="" also="" associated="" by="" characterized="" consuming="" diet="" dietary="" fiber="" for="" found="" hbp.="" higher="" in="" individuals.="" intakes="" kg="" led="" long-term="" lower="" m2="" more="" o:p="" of="" percent="" protein="" reductions="" risk="" risks="" that="" the="" they="" to="" was="" when="" with="">25>
"These results provide no
evidence to suggest that individuals concerned about the development of HBP
should avoid dietary protein. Rather, protein intake may play a role in the
long-term prevention of HBP," explained corresponding author Lynn Moore,
associate professor of medicine at BUSM. "This growing body of research on
the vascular benefits of protein, including this study, suggest we need to
revisit optimal protein intake for optimal heart health," she added.
