Diet Containing Carbohydrates Heightens Risk of Hypertension, Study Finds

A recent study has found that diets containing carbohydrates, regardless of amount or level of consumption, may contribute to new-onset hypertension, even with minimal risk evident at 50 ~ 55 percent carbohydrate consumption.

Research monitored a total of 12,177 adults who were free of hypertension at baseline from the China Health and Nutrition Survey. Dietary consumption was assessed via three consecutive 24-hour dietary recalls mixed with a household food inventory. The result of the new-onset hypertension was described as systolic blood pressure (SBP) > 140mm Hg or diastolic blood pressure (DBP) > 90mm Hg, a diagnosis by a doctor, or receipt of antihypertensive treatment during the follow-up.


A total of 4,269 individuals who developed hypertension over 95,157 person-years of follow-up. A U-shaped correlation emerged between the percentage energy consumed from total carbohydrate (average 56.7 percent) and new-onset hypertension.


It was noted that participants with 50 – 55 percent carbohydrate intake had the lowest risk, while those with lower intake of high-quality carbohydrate (average, 6.4 percent) or higher intake of low-quality carbohydrate (average, 47 percent) had heightened risk of hypertension.


The new-onset hypertension showed an inverse correlation with the plant-based low-carbohydrate scores for low-quality carbohydrate. Alternatively, the correlation observed with the animal-based low-carbohydrate scores for low-quality carbohydrate followed a U-shaped pattern.


Current data support the consumption of high-quality carbohydrate and the replacement of plant-based products for low-quality carbohydrates in the prevention of hypertension, according to researchers.
