Professor Jennifer Di Noa of William Paterson University introduces an exciting new way to think about the healthiest fruits and vegetables. These “powerful fruits and vegetables” are packed with nutrients that help prevent long-term diseases like heart disease and cancer. Her findings, published in the journal Preventing Chronic Disease, provide a simple way to determine which fruits and vegetables provide the greatest caloric benefits to our health.
The research focuses on important nutrients our bodies need to stay healthy, such as vitamins, minerals, protein and fiber. These nutrients are called essential nutrients because the body cannot produce them on its own, and they are key to reducing the risk of chronic disease. To be classified as an energy fruit or vegetable, a food must contain significant amounts of these nutrients compared to its caloric content (a measure of the energy a food provides). Of the foods studied, most met this high standard. Vegetables like watercress, spinach, and kale top the list and provide a ton of nutrients. Some fruits, such as strawberries and oranges, also made the list, albeit lower in the rankings. Interestingly, everyday foods such as potatoes and bananas are not included because their nutritional content is relatively low compared to calories.
“This study provides a standardized approach to identifying the most nutrient-dense fruits and vegetables,” shared Professor DiNoia. “By focusing on nutrient density, we empower consumers to make informed food choices for their health.” Nutrient density refers to the amount of beneficial nutrients in a food relative to its calorie content.
Research has also tested the reliability of this classification system and found it to be highly effective. It provides a clear way to help people understand which foods are better for their health. For example, the system highlights nutrient-dense foods like leafy greens and cruciferous vegetables, the plant family that includes broccoli, cauliflower and cabbage, making it easier for consumers to make healthy choices.
The results of this study are expected to play an important role in public health education aimed at improving community health through dietary and lifestyle recommendations. They provide a practical tool to guide people to eat a more nutritious diet. However, the study did note some limitations. It does not include some plant compounds called phytochemicals, which are natural substances in plants that may have additional health benefits. Incorporating these into future studies could further improve the system.
Ultimately, this new method could make it easier to identify the healthiest fruits and vegetables. By focusing on foods that provide the most nutrients, people can make better choices that support their health and reduce the risk of chronic disease.
