Anthocyanin-Rich Foods May Boost Heart and Metabolic Health
Some fruits and vegetables are red, purple, or blue because they contain special plant helpers called anthocyanins.
Berries, like blueberries, have lots of these helpers.
Scientists reviewed many studies about these colourful foods.
They found that people who ate more anthocyanins were 26% less likely to get heart disease.
They were also 18% less likely to have a heart attack, and their chances of getting type 2 diabetes were 11% lower.
The foods helped blood vessels work better and helped keep blood sugar levels healthy.
Eating about 50 milligrams a day was enough, which is easy with foods like blueberries.
The findings matter especially for India, where heart disease and diabetes are growing problems.
But no single food is a magic cure, and a balanced diet, exercise, sleep, and medical care matter most.
A systematic review and meta-analysis in The American Journal of Clinical Nutrition found higher anthocyanin intake is associated with a 26% lower risk of cardiovascular disease.
Higher anthocyanin intake was linked to an 18% lower risk of myocardial infarction (heart attack), an 11% lower risk of type 2 diabetes, a 9% lower risk of cardiovascular mortality, and an 8% lower risk of hypertension.
Researchers analysed 18 prospective cohort studies reported across 27 publications and 65 randomised controlled trials involving adults without diagnosed disease.
Randomised controlled trials showed improvements in blood-vessel function and insulin concentrations at dietary anthocyanin intakes of 50 mg per day.
Findings are described as especially relevant for India, where cardiovascular disease, diabetes and hypertension are growing public health concerns, with USA blueberries cited as an easily incorporated anthocyanin source.
