Diet is considered to play the most crucial role in maintaining physical health. Everything we consume has a direct impact on our well-being; this is why health experts advise everyone to regularly consume nutritious foods.

However, as dietary habits deteriorate, the body is gradually becoming deficient in the essential nutrients required daily.
This is the reason behind the rapid rise in issues such as high blood pressure, diabetes, heart disease, and weakened immunity, even among younger people. Yet, the good news is that the easiest way to avoid these risks lies not in expensive medicines or supplements, but right on your daily dinner plate.
**The Importance of Flavanols**
Studies indicate that colorful fruits and green leafy vegetables—such as spinach, fenugreek, and broccoli—are rich in natural compounds known as flavanols. These are not merely nutrients; they act as a protective shield for the body's cells.
Scientists believe that natural flavanols play a vital role in improving blood vessel function, reducing oxidative stress in the body, and strengthening heart health.
While consuming fruits and vegetables daily is recommended for good health, simply increasing the quantity is not enough; the choice of foods matters just as much. A recent study revealed that most people do not consume foods containing natural flavanol compounds—compounds known to reduce the risk of death from heart disease.
**What Did the Study Reveal?**
This study, conducted by scientists from the University of Reading, Harvard Medical School, and several other universities, was published in the journal *Food & Function*.
Researchers analyzed dietary data and biological markers from over 30,000 individuals across the United States and the United Kingdom. The study found that fewer than 20% of people were consuming flavanols at the levels required by the body.
Surprisingly, many people failed to consume adequate flavanols despite eating five servings of fruits and vegetables daily.
What do the experts say?
Professor Gunter Kuhnle from the University of Reading states that while the recommendation to eat five servings of fruits and vegetables a day is sound, it is now necessary to understand exactly which five options are chosen. Different fruits and vegetables provide not only vitamins and minerals but also various bioactive compounds that can have distinct effects on health.

Plums, cranberries, blackberries, beans, cherries, strawberries, and blueberries are generally considered the best sources of flavanols.
According to lead author Dr. Javier Ottaviani, people often assume that eating fruits and vegetables provides all necessary nutrients, but the reality is different. Including specific fruits, vegetables, and beverages in one's diet can significantly boost flavanol intake.
