A new analysis suggests the kinds of fruits and vegetables you eat matter for heart protection — not just how many. Researchers who tracked about 30,000 people using biomarker measurements found most people fall short of the flavanol intake associated with lower cardiovascular risk.
Why flavanols matter
Flavanols are plant compounds found in many fruits, vegetables, tea, and some legumes. Evidence from the large COSMOS randomized trial indicates that about 500 milligrams (mg) of flavanols per day was linked with up to a 27% lower risk of death from cardiovascular disease. The recent study used COSMOS data plus an independent population sample to ask whether common fruit-and-vegetable recommendations deliver that level of flavanols — and the answer was generally no.
Not all produce is equal
While all fruits and vegetables add nutritional value, they vary widely in flavanol content. The study and supporting research identify several especially rich sources (approximate flavanol amounts):
– Plums (500 g): ~450 mg
– Cranberries (250 g): ~300 mg
– Blackberries (200 g): ~250 mg
– Green tea (250 ml cup): ~200 mg
– Broad/fava beans (80 g): ~140 mg
– Cherries (400 g): ~130 mg
– Apples with skin (200 g, one medium): ~110 mg
– Strawberries (200 g): ~90 mg
– Blueberries (150 g): ~80 mg
– Pinto beans (40 g dry): ~70 mg
How to put this into practice
– Aim for variety: Build a plant-rich diet, but intentionally include flavanol-rich choices several times a week. Berries, apples with skin, plums, and a daily cup of green tea are easy ways to boost intake.
– Small, consistent habits work best: Add berries to cereal or yogurt, snack on an apple, swap a sugary drink for tea, or include beans in salads and soups.
– Don’t ignore overall produce intake: Many people still don’t meet basic fruit-and-vegetable recommendations. Increasing total produce is the first priority; then favor higher-flavanol options within that pattern.
What this means for guidelines
The findings suggest that current broad recommendations to eat more fruits and vegetables may not guarantee intake of specific beneficial compounds like flavanols. Rather than promoting a single “superfood,” the practical takeaway is to pair a balanced, plant-rich diet with regular inclusion of the highest-flavanol items.
Bottom line
Flavanols appear to offer meaningful cardiovascular protection when consumed at sufficient levels. Most people don’t reach the roughly 500 mg/day shown to reduce cardiovascular mortality, but choosing flavanol-rich fruits, beans, and tea more often can help bridge that gap. Focus first on meeting general produce recommendations, then make simple, enjoyable swaps to increase flavanol-rich choices for long-term heart health.
