Frequent Fruit Juice Consumption Linked to Higher BP

the MPR take:

While excess sugar intake from daily consumption of soft drinks has been linked to high blood pressure (BP), is there also an association between habitual fruit juice consumption and BP? Published in the journal Appetite, 146 community-dwelling male and female volunteers between the ages of 50–70 without a history of neurological or psychiatric illness, cardiovascular disease, and diabetes were surveyed on dietary patterns from an in-house food frequency questionnaire. Participants were asked to recall their consumption of various foods and beverages over the past 12 months, with fruit juice consumption grouped into categories of rare use (never to no more than three times/month), occasional use (once per week to 5–6 times/week), and daily use (once per day to >3 times/day). Brachial blood pressure was assessed in three sequential BP measurements taken from the left arm followed by a central BP measurement. Those who consumed fruit juice daily had significantly higher central systolic BP and augmentation pressure, estimated at 3mmHg and 4mmHg higher than those who consumed rarely or occasionally. Lower PPA (pulse pressure amplification) and higher central pulse pressure were also associated with daily fruit juice consumption, even after controlling for LDL and HDL cholesterol levels. Fruit juices may contain important vitamins and minerals for older populations, but they are also high in sugar with minimal amounts of fiber; raw fruit is a better option, with no known evidence of increasing BP.

Despite a common perception that fruit juice is healthy, fruit juice contains high amounts of naturally occurring sugar without the fibre content of the whole fruit.
