Blueberry consumption good for heart: Study
University of East Anglia (UK), September 3, 2019
Eating 150 grams of blueberries daily reduces the risk of cardiovascular disease by up to 15 per cent, claim researchers.
The research team from UEA's Department of Nutrition and Preventive Medicine, Norwich Medical School, said that blueberries and other berries should be included in dietary strategies to reduce the risk of cardiovascular disease -- particularly among at-risk groups.
The team investigated the effects of eating blueberries daily in 138 overweight and obese people, aged between 50 and 75, with Metabolic Syndrome. The six-month study was the longest trial of its kind. They looked at the benefits of eating 150-gram portions (one cup) compared to 75-gram portions (half a cup). The participants consumed the blueberries in freeze-dried form and a placebo group was given a purple-coloured alternative made of artificial colours and flavourings.
"We found that eating one cup of blueberries per day resulted in sustained improvements in vascular function and arterial stiffness -- making enough of a difference to reduce the risk of cardiovascular disease by between 12 and 15 per cent," said co-lead, Dr Peter Curtis.
