Plant-based diet cuts heart failure risk by over 40 percent

New research finds that sticking to a diet rich in fruits, vegetables, and fish can slash heart failure risk by 41 percent. By contrast, a diet rich in fats, fried foods, processed meat, and sugary drinks can raise the risk of this condition.
 Heart failure occurs when the heart cannot supply enough blood and oxygen to the main organs in the body.The condition affects about  26 millionpeople worldwide.
Emerging evidence suggests that a diet consisting mainly of fruits and vegetables can prevent cardiovascular disease. Now, a new study strengthens this idea.
Dr. Kyla Lara, a cardiology fellow at the Mayo Clinic in Rochester, MN, and her colleagues, have examined the associations between five major dietary patterns and the risk of heart failure among people without any known history of heart disease.
Dr. Lara and her team published the results of their study in the Journal of the American College of Cardiology.
The researchers examined data available from the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study. Namely, they looked at the dietary patterns among 16,068 black and white people who were 45 years old, on average.
The participants answered a 150-item survey, which included 107 food items. The researchers grouped the foods into five dietary patterns:
*    "convenience" diets, which consisted of meat-heavy dishes, pasta, pizza, and fast food
*    "plant-based" diets, consisting mainly of vegetables, fruit, beans, and fish
*    "Southern" diets, which comprised a significant amount of fried foods, processed meat, eggs, added fats, and sugary drinks
*    "alcohol/salads" diets, which included lots of wine, liquor, beer, leafy greens, and salad dressing.
Dr. Lara and team followed the participants for 8.7 years on average, during which time, 363 people spent time in the hospital for heart failure for the first time.
Of these, 133 people had heart failure with preserved ejection fraction, and 157 had heart failure with reduced ejection fraction. The former refers to a form of heart failure in which the ejection fraction - a measure of how well the heart is pumping blood - is "normal," or "preserved."
Overall, the researchers found that adhering to the Southern diet increased the risk of hospitalization due to heart failure by 72 percent.
But when the researchers adjusted for body mass index (BMI), "waist circumference, hypertension, dyslipidemia, diabetes mellitus, atrial fibrillation, and chronic kidney disease," this association became no longer statistically significant.
This could mean that the Southern diet raises heart failure risk by increasing obesity and abdominal fat, explain the researchers.
Importantly, the researchers found that the risk of heart failure hospitalizations was 41 percent lower among people who adhered to the plant-based diet.
Finally, the researchers found no statistically significant associations among heart failure risk and the other three dietary patterns.




"Adherence to a plant-based dietary pattern was inversely associated with incident [heart failure] risk, whereas the Southern dietary pattern was positively associated with incident [heart failure] risk," conclude the researchers, who also outline some strengths and limitations to their study.
