Mejia presented his findings this month at the American Society for Nutrition’s annual meeting in Boston.
The program revolves around following a vegan diet with primarily plant-based foods such as fruits and vegetables, legumes, whole grains, seeds, and nuts.
These results are equivalent to the effects of standard blood pressure medications. In all, 93 percent of the participants were able to reduce their dose or eliminate medications entirely.
While it requires a substantial amount of willpower, making lifestyle changes should always be first and foremost for people who want to lower their blood pressure, according to an expert interviewed by Healthline.
Results Not Surprising
Dr. Andrew Freeman, a cardiologist at the National Jewish Health in Colorado, says the findings make plenty of sense.
“Exercise, particularly cardio and aerobic exercise, has been known to be a potent dropper of blood pressure for a long time, and we know that fruits and vegetables rich in potassium and naturally occurring nitrates can actually lower blood pressure as effectively as many of the medications,” he said. “So that, to me, is no surprise. It’s nice that they put it all together in this study.”
But even for patients who are prescribed medications for high blood pressure, lifestyle will always be a factor.
Freeman points to a 2017 study that he co-authored in which 90 percent of the more than 900 cardiologists surveyed reported that they’d received no or minimal nutrition education during their training.
It’s Simple, But It Takes Work
For people who want to lower their blood pressure, it isn’t easy to hear that they need to change their diet and get more physical activity.
But when it comes to blood pressure and cardiovascular health, there really aren’t any shortcuts.
While virtually all patients will see promising results just a few weeks after incorporating lifestyle changes, they’ll need to continue the regimen in order to maintain good health.
Freeman says that for patients who have mildly elevated blood pressure, he’ll recommend a multi-week program of lifestyle changes. Generally, blood pressure levels normalize in this time.
While patients who follow this plan might initially miss eating their favorite foods, he says the results tend to speak for themselves.
“Every so often I’ll get a call from a patient who says they’re feeling miserable and it turns out they’ve implemented the lifestyle modification and their blood pressure has dropped so much that we have to get rid of the medicine, which is great,” he says.
When it comes to aiding cardiovascular health and bringing blood pressure down, Freeman says, there are four tenets to follow in terms of lifestyle change.
The first two are following a predominantly plant-based, whole food, unprocessed diet combined with getting at least 30 minutes of moderately rigorous, restless exercise per day.
“This does not mean I want them exercising so hard that they pass out, but I want them to be challenged, even if it means taking a break if they have to,” he said. “For some people, that may mean nothing more than a gentle walk with periodic breaks, but as the weeks go on, they need to challenge themselves to get rid of those breaks, little by little.”
The third facet is stress relief techniques such as yoga, introspection, and other mindfulness exercises.
“The last part, believe it or not—and this is based on Dean Ornish’s work—is actually connections, support, and love,” explained Freeman. “We know that people that have the most connections, support, and love have the best cardiovascular outcomes.”
“When you combine all four of those—eating plants, exercising more, stressing less, and loving more—health outcomes improve in lots of categories, including blood pressure and coronary disease. So that’s really what I try to get patients to do.”
