Researchers suggest that even individuals adhering to the "five-a-day" fruit and vegetable recommendation may not be consuming sufficient flavanols, a crucial antioxidant group linked to cardiovascular health. Studies involving 30,000 participants from the US and UK revealed that fewer than 20% ingest the recommended 500mg daily intake of flavanols. Foods like plums, cranberries, blackberries, green tea, and broad beans are identified as particularly rich sources. While flavanols can reduce the risk of cardiovascular disease, the specific types of fruits and vegetables consumed are deemed more important than the total quantity, emphasizing the need for more targeted dietary guidance.
