Nearly half of adults in the United States have hypertension, according to the CDC. Most of these cases could be prevented and reversed with plant-based lifestyle medicine, and this evidence dates back almost a century ago. Discover the foods and lifestyle changes scientifically proven to help below.

Cases per year

In 2020, more than 670,000 deaths in the United States had hypertension as a primary or contributing cause.

General frequency

Over 103 million people, or 46% of the US population 1


Hypertension is a major risk factor for heart disease which causes 1 in 4 deaths in the US.

Treating hypertension with a whole-food plant-based diet and lifestyle medicine

The joy felt by myself and my patients when we can decrease their blood pressure medication because of lifestyle modifications they have made is incredible!

Plant-based diets reduce the risk of hypertension by 60%

Health and sustainability outcomes of vegetarian dietary patterns: a revisit of the EPIC-Oxford and the Adventist Health Study-2 cohorts 

Vegetarians and vegans had up to a 60% reduced risk of high blood pressure compared to omnivores in the Adventist Health Studies and EPIC-Oxford study2

Lifestyle interventions effectively lower raised blood pressure

Lifestyle interventions to reduce raised blood pressure: a systematic review of randomized controlled trials 

This study took the results from 105 separate trials involving 6805 participants, and found that lifestyle interventions could consistently and significantly lower blood pressure. Successful interventions including improving diet, doing aerobic exercise, restricting alcohol and sodium intake all lowered pressure in participants. Diet was the most effective with an average 5.0 mmHg reduction in systolic blood pressure 3

Plant-based diets are key to low blood pressure

Long-term low-calorie low-protein vegan diet and endurance exercise are associated with low cardiometabolic risk 

This interesting study compared 3 groups: sedentary and plant-based, endurance running omnivores, and sedentary omnivores. Whilst the endurance athlete-omnivores had lower blood pressure than sedentary omnivores, people who were sedentary but ate plant-based actually had lower blood pressure than the endurance athletes! This was a small study, yet the results provide positive data for plant-based diets. If blood pressure is your ultimate goal, it’s possibly better to be sedentary and plant-based, than an omnivore who runs 48 miles a week! (at Mora we advocate for both a plant-based diet and exercise for maximum health benefits) 4

What is hypertension?

Hypertension (high blood pressure) is where you have sustained high blood pressure readings. 

Blood pressure is the force of the blood pushing against the walls of the arteries, as it flows from the heart to the rest of the body. 

Primary hypertension represents most cases, where there is no single cause of high blood pressure; it is mostly due to diet and lifestyle factors including lack of physical activity, too much salt in the diet, and too much alcohol. 

Some people have secondary hypertension where the hypertension can be linked to a specific cause e.g. medication or a medical condition. 


Hypertension is often referred to as the ‘silent killer’ because most people have no symptoms. However, those with more severe high blood pressure may experience symptoms such as headaches, chest pain, and shortness of breath. 

Sustained high blood pressure is the leading risk factor for death because of its far-reaching detrimental effects. It puts strain on the heart, and can damage blood vessels in the eyes and kidneys. High blood pressure increases your risk of heart attack, heart failure, stroke, and kidney failure, as well as damage to other organ systems 5. It also increases the risk of conditions such as vascular dementia. 


Your blood pressure reading is taken with a blood pressure monitor (sphygmomanometer). 

When you have a blood pressure reading, you get two measurements:

  • The top number is systolic blood pressure - this is the pressure in your arteries when the heart contracts and sends blood around the body  
  • The bottom number is diastolic blood pressure - this is the lowest pressure in your arteries, when the heart relaxes and refills with blood, ready to pump again  

The readings correlate to different stages of hypertension:


The American Heart Association (AHA) and the American College of Cardiology (ACC) recommend diet and lifestyle changes as the first treatment for high blood pressure. 

The evidence shows us that diets rich in plant-foods and lower in animal foods should be the main treatment option for hypertension, combined with the other pillars of lifestyle medicine. 

Several mechanisms are behind the pressure-lowering power of a plant-based diet. Firstly, those who eat plant-based diets have lower BMIs and a lower risk of obesity 6. This is mostly due to the high fiber and low fat content of the diet, reducing its overall energy density 7. Obesity is a known risk factor for high blood pressure.

They are also high in other compounds that regulate blood pressure: 

  1. Plant-based diets are high in potassium which lowers blood pressure and reduces the risk of stroke. It relaxes blood vessels, whilst reducing both the reabsorption of sodium into the kidney, and the production of reactive oxygen species 8 9. Most Americans on a typical western diet do not consume enough potassium 10
  2. Dietary nitrate is also a friend of low blood pressure. It gets converted to nitrites, and then to nitric oxide which relaxes our blood vessels and maintains low blood pressure. Leafy green vegetables and beetroot are excellent sources. They help to improve endothelial function and arterial stiffness, which both affect blood pressure 11. The nitrites added to processed meats, like bacon, do not have the same healthful effects. Combined, their protein content and high cooking temperatures convert nitrites into nitrosamines, instead of nitric oxide, which can increase cancer risk 12 13
  3. Plant-based diets are high in whole grains, which have been shown to significantly lower blood pressure. Scientists estimate that 3 portions of whole grains a day reduces blood pressure and subsequent risk of coronary artery disease by more than 15%, and stroke by 25%. You could cut your risk of stroke by a quarter, just by having some oats for breakfast, and buckwheat and barley for tea! 14

Plant-based diets are low in compounds that increase blood pressure:

  1. Low in saturated fat. Saturated fat increases blood pressure because it impairs endothelial function, which affects how much the blood vessels can relax. Red and processed meat, and poultry are major sources of saturated fat on a western diet, and all independently increase blood pressure 15 16. In contrast, polyunsaturated fats can lower blood pressure, found in walnuts and flaxseeds 17
  2. Low in AGE content. The cooking of meat, poultry, and fish can generate advanced glycation end-products (AGEs) that increase levels of inflammation and oxidative stress, known risk factors for high blood pressure. Plant-based foods including fruits, carbohydrates, and vegetables contain much lower levels of AGEs, and are high in antioxidants which combat oxidative stress 16
  1. Reduced sodium. A plant-based diet cuts out processed foods and meats filled with excess salt, which we know is a major risk factor for high blood pressure.
  2. Reduced alcohol consumption is encouraged as part of a whole-food plant-based diet. Excess alcohol increases the risk of high blood pressure through several mechanisms, it can directly affect the heart and decrease nitric oxide production 5 18

At Mora, we’ve seen people thrive on a plant-based diet and, with physician support, make an easy transition followed by incredible changes on blood pressure readings. 

Choosing an active plant-based lifestyle can take the pressure off for good.
