Healthy eating during early adulthood can influence health for decades. Many people think all vegetables provide the same benefits, but new research suggests the story may be more complex.
Scientists from Edith Cowan University found that certain vegetables may offer greater protection against heart disease and type 2 diabetes depending on whether a person is male or female. Their findings suggest that even small changes in eating habits during your 20s may help lower the risk of serious diseases later in life.
The researchers analysed information from the Raine Study, a long-term Australian project that has followed participants from before birth into adulthood.
The study includes detailed information about diet, lifestyle, blood tests, body measurements and overall health. Using this valuable database, the researchers examined the eating habits of young adults and compared them with early warning signs of heart disease and diabetes.
The results showed clear differences between men and women. Young men who regularly ate more legumes, including beans, lentils and peas, were less likely to have early signs of heart disease.
Young women who ate more cruciferous vegetables, such as broccoli, cauliflower and cabbage, had lower levels of risk factors linked with both heart disease and type 2 diabetes. Researchers believe natural plant compounds may interact differently with male and female hormones, although more studies are needed to understand exactly why.
The encouraging news is that participants did not need to make dramatic changes. Adding just one extra serving of the most beneficial vegetables each day was linked with healthier blood pressure, waist size, cholesterol, blood sugar and triglyceride levels.
Nearly one in five young adults already had several of these warning signs despite being only in their twenties, showing that chronic disease risk can begin much earlier than many people expect.
The researchers also pointed out that beans, broccoli and other vegetables identified in the study are widely available and relatively inexpensive, making them practical choices for most families. They hope the findings encourage young adults to build healthy eating habits before health problems develop.
The research was published in Nutrition, Metabolism and Cardiovascular Diseases.
Overall, this study provides interesting evidence that men and women may not receive exactly the same health benefits from every type of vegetable. One strength is that it used data from the long-running Raine Study, which has followed participants for decades.
However, this was an observational study, meaning it found links rather than proving that the vegetables directly caused the health benefits. Other lifestyle factors, such as exercise, sleep, and overall diet, may also have influenced the results.
Larger clinical trials will be needed to confirm whether eating specific vegetables truly produces different effects in men and women. Even so, the findings support current advice that eating a wide variety of vegetables every day is an important way to protect long-term health.
