One study explored the effect of different vegetarian diets on high blood pressure and found that the Healthy Vegetarian Diet Index (hPDI) was the first.
Little is known about the specific role that different plant-based diets play in hypertension.
A study published in the British Medical Journal sought to address this gap by putting different vegetarian diets together.
The researchers compared three vegetarian diets: the Vegan Diet Index (PDI), the Healthy Vegetarian Diet Index (hPDI), and the Unhealthy Vegetarian Diet Index (uPDI).
PDI emphasizes the consumption of all plant foods while minimizing the intake of foods of animal origin. While hPDI emphasizes the consumption of healthy plant foods associated with better health outcomes, such as whole grains, fruits and vegetables.
Finally, uPDI emphasizes the consumption of less healthy plant foods that are known to be associated with an increased risk of many diseases.
The researchers used cross-sectional data from 4,680 men and women, aged 40 to 59, in Japan, China, the United Kingdom and the United States, from the International Study of Micronutrients / Micronutrients and Blood Pressure (INTERMAP).
INTERMAP is an investigation of the relationships between micro-intakes, macronutrients, and blood pressure.
The main finding of the study was that hPDI was inversely related to the decrease in blood pressure, while uPDI was inversely related to blood pressure.
The researchers concluded that “vegetarian diets rich in vegetables and whole grains and limited to refined grains, sugary drinks and whole meats may contribute to these associations.”
Reducing salt is essential – the more salt you eat, the higher your blood pressure.
In addition to improving your diet, exercise is the key to lowering high blood pressure, according to Express.
