Flavanol-Rich Fruits and Vegetables Could Boost Heart Health, New Study Finds

Research Suggests Most People Are Not Getting Enough Heart-Protective Flavanols

A new study has revealed that many people may be missing out on an important group of natural compounds known as flavanols, which could play a significant role in protecting heart health and reducing the risk of cardiovascular disease.

While health experts have long encouraged people to eat more fruits and vegetables, researchers now say that the specific types of produce people choose may be just as important as the quantity they consume.

The findings, published in the journal Food & Function, suggest that consuming around 500 milligrams of flavanols daily may significantly reduce the risk of dying from cardiovascular disease.

What Are Flavanols?

Flavanols are naturally occurring plant compounds that belong to a larger group of nutrients called polyphenols. They are found in a variety of foods and drinks, including:

• Apples
• Berries
• Plums
• Cherries
• Green tea
• Beans
• Cocoa products

Scientists have been studying flavanols for years because of their potential health benefits, particularly their ability to support healthy blood vessels and improve circulation.

Why Are Flavanols Important for Heart Health?

According to the researchers, flavanols may help lower inflammation, improve blood vessel function, and support overall cardiovascular health.

The study’s lead author, Dr. Javier Ottaviani, Director of the Core Laboratory of Mars Edge, explained that simply eating fruits and vegetables may not be enough if people are not choosing foods rich in flavanols.

He noted that flavanols can substantially reduce the risk of death from cardiovascular disease, but only when consumed in sufficient amounts.

The research highlights that small dietary choices—such as eating blackberries, enjoying an apple with its skin, or drinking green tea—can make a meaningful difference to flavanol intake.

Study Tracked 30,000 People in the UK and US

Researchers analysed dietary data from approximately 30,000 participants across the United Kingdom and the United States.

The team used biomarker measurements to assess flavanol consumption and compared the findings with recommendations from major dietary guidelines.

The study was based on findings from the large-scale COSMOS trial, one of the biggest randomised controlled studies investigating polyphenols and their health effects.

Key Finding

The COSMOS study previously found that consuming around:

500 mg of flavanols per day

was associated with:

• Up to 27% lower risk of death from cardiovascular disease
• Improved heart health outcomes
• Better blood vessel function

However, the new research found that most participants failed to reach this target, even when following general healthy eating advice.

Current Dietary Guidelines May Not Be Enough

Many countries already encourage higher fruit and vegetable consumption.

Current Recommendations

United States

The Dietary Guidelines for Americans recommend:

• 2–3 servings of fruits and vegetables daily

United Kingdom

The NHS recommends:

• At least 5 portions of fruits and vegetables each day

Despite these recommendations, researchers found that many people still consumed insufficient amounts of flavanol-rich foods.

The study suggests that focusing on specific flavanol-rich choices may provide additional heart-health benefits beyond simply meeting minimum fruit and vegetable targets.

Nutrition Experts Support Findings

Preventive cardiology dietitian Michelle Routhenstein, who was not involved in the research, said the findings offer valuable insight into making healthier food choices.

She explained that while all fruits can contribute to a healthy diet, regularly selecting flavanol-rich options such as berries and apples may provide extra cardiovascular protection.

According to Routhenstein, the study is not encouraging people to focus on a few so-called “superfoods.” Instead, it highlights the importance of choosing nutrient-rich foods within a balanced dietary pattern.

Which Foods Contain the Highest Levels of Flavanols?

Researchers identified several fruits, vegetables, and beverages that are particularly rich in flavanols.

Top Flavanol-Rich Foods

These foods can easily be included in everyday meals and snacks to help boost flavanol intake.

Simple Ways to Increase Flavanol Intake

Health experts recommend making small, sustainable changes rather than drastically changing eating habits.

Easy Ideas Include:

• Adding berries to breakfast cereals or yoghurt
• Eating an apple as a daily snack
• Drinking green tea instead of sugary beverages
• Including beans in soups, salads, or stews
• Mixing cherries or blueberries into smoothies
• Keeping fresh fruit readily available at home

Routhenstein emphasised that choosing one or two favourite flavanol-rich foods and consuming them regularly is often more effective than trying to eat every flavanol-rich food available.

Experts Say Overall Diet Still Matters Most

Although flavanols appear beneficial, nutrition experts stress that overall diet quality remains the most important factor for long-term health.

Many people still struggle to meet basic fruit and vegetable intake recommendations. Therefore, the priority should be increasing overall consumption of plant-based foods while gradually incorporating more flavanol-rich options.

Experts believe that building a diverse, plant-rich diet remains the best strategy for reducing cardiovascular disease risk and supporting long-term wellbeing.

Key Takeaways From the Study

The Main Findings

• Most people are not consuming enough flavanols.
• Around 500 mg of flavanols daily may reduce cardiovascular disease mortality risk by up to 27%.
• Certain fruits, vegetables, beans, and teas contain significantly higher flavanol levels.
• Apples, berries, plums, cherries, beans, and green tea are among the best sources.
• Small dietary changes can meaningfully increase flavanol intake.
• A balanced, plant-rich diet remains the foundation of heart health.

Conclusion

The latest research provides further evidence that not all fruits and vegetables offer the same nutritional benefits when it comes to heart health. While eating plenty of produce remains essential, choosing flavanol-rich foods such as apples, berries, plums, beans, and green tea could provide additional protection against cardiovascular disease.

As scientists continue to explore the connection between diet and heart health, one message is becoming increasingly clear: making smarter food choices today could lead to a healthier heart tomorrow.
