Flavanol-Rich Fruits and Vegetables May Boost Heart Health: Here’s What You Need to Know

A recent study has highlighted a concerning trend: many individuals are not consuming adequate amounts of flavanols, natural compounds found in various fruits and vegetables that are linked to improved heart health. Researchers indicate that an intake of around 500 milligrams of flavanols daily can significantly lower the risk of death from cardiovascular diseases.

While dietary guidelines generally advise eating 2 to 3 servings of fruits and vegetables daily, with some recommendations going as high as 5 portions, the study published in *Food and Function* reveals a gap in actual consumption of flavanols among many people. This suggests that simply eating fruits and vegetables may not be enough; it’s crucial to choose those that are higher in flavanols to gain maximum health benefits.

Dr. Javier Ottaviani, the study’s lead author and a researcher at Mars Inc., emphasizes the importance of making informed choices within the broader category of fruits and vegetables. He notes that while many people believe they are meeting their nutritional needs by eating an adequate amount of produce, the specific types of fruits and vegetables consumed play a crucial role in overall flavanol intake. For instance, incorporating options like blackberries, apples, and green tea into your diet can substantially enhance flavanol consumption.

The research tracked the dietary habits of over 30,000 participants in the United States and the United Kingdom, utilizing biomarker measurements to assess flavanol intake. Previous studies, including one from the COSMOS trial, indicated that consuming 500 mg of flavanols per day could reduce the risk of cardiovascular mortality by as much as 27%. However, findings from the current study show that most individuals fall short of this target, even when following standard healthy eating guidelines.

Nutrition experts emphasize that while all fruits can contribute to a healthy diet, prioritizing those rich in flavanols can offer additional cardiovascular benefits. Michelle Routhenstein, a preventive cardiology dietitian, suggests that individuals should focus on incorporating a few flavanol-rich foods into their regular diets rather than attempting to consume all available options. For example, regularly adding berries to breakfast or opting for green tea instead of sugary beverages can be effective strategies for increasing flavanol intake.

Research indicates that several fruits and vegetables are particularly high in flavanols. Plums, cranberries, blackberries, and green tea are among the top choices, with plums providing approximately 450 mg of flavanols per 500 grams and cranberries offering around 300 mg per 250 grams. Other notable sources include cherries, apples, and various beans.

As the conversation around dietary recommendations evolves, experts acknowledge that while increasing flavanol intake is beneficial, it’s essential first to achieve the basic goal of sufficient fruit and vegetable consumption. Simple, sustainable changes in diet can help people meet their nutritional needs while enhancing overall heart health. Ultimately, the focus should be on developing a plant-rich dietary pattern that supports long-term cardiovascular wellness.
