Polyphenol-Rich Foods May Have Cardiometabolic Protective Effects
Polyphenols act as antioxidants and help protect cells and body
chemicals against damage caused by free radicals. A new study suggests that
consuming polyphenol-rich bilberries, lingonberries, and cinnamon for breakfast
may offer cardiometabolic protective effects.
Thirteen healthy but overweight adults participated in the study.
All the participants underwent four interventions, each separated by a six-day
washout period. The night before each intervention, the participants ate a
standardized meal of spaghetti, tomato sauce, chicken, cheese, and soybean oil.
For the intervention, they consumed a high calorie/high fat breakfast of 910
calories with a fat contribution of 455 calories, or one of three breakfasts
that incorporated 3 grams of cinnamon, 100 grams of bilberries, and 100 grams
of lingonberries into the high calorie/high fat breakfast. Circulating
biomarkers associated with cardiometabolic risk were measured post-meal for 4
The researchers found that consumption of bilberries and
lingonberries reduced the elevation of cholesterol typically caused by a high
fat meal. Consumption of bilberries also had regulating effect on triglyceride
response to the high fat meal. Consumption of cinnamon reduced glycemic
response and postprandial endotoxemia.
The study was conducted by researchers from the University of
Campinas, Brazil and the Food for Health Science Centre, Sweden. It was
published online ahead of print on July 4, 2019 in the Journal
of Functional Foods.
