Many people believe serious diseases only become a concern later in life. However, scientists now know that the foundations of future health are often built during young adulthood.
A new Australian study suggests that the vegetables people eat in their twenties may influence their chances of developing heart disease and type 2 diabetes many years later. Interestingly, the vegetables that appear to provide the greatest benefit are not exactly the same for men and women.
Researchers at Edith Cowan University studied data collected through the famous Raine Study, which has tracked thousands of Australians for 37 years. Because participants have provided regular health information since before birth, the project allows scientists to investigate how early lifestyle choices affect health later in life.
When researchers compared vegetable intake with markers of future disease, they found an important pattern. Men who ate more legumes such as beans, lentils and peas had fewer early signs linked with cardiovascular disease.
Women who ate higher amounts of broccoli, cauliflower, cabbage and other cruciferous vegetables showed healthier measures related to both diabetes and heart disease. Scientists think the different plant compounds in these vegetables may affect male and female hormones in different ways, but further research is needed before firm conclusions can be made.
The study also highlighted an important public health message. Many participants were only in their early twenties, yet almost twenty percent already had several risk factors for chronic disease.
High blood pressure, increased waist size, unhealthy cholesterol, raised blood sugar and high triglycerides often develop quietly without symptoms. Healthy eating at a young age may help slow or prevent these changes.
Perhaps the most practical finding was that the benefits were linked with only one extra serving of vegetables each day. This means small improvements to daily meals could produce meaningful long-term health benefits.
The vegetables highlighted in the study are affordable, widely available and easy to include in soups, salads, stir-fries and other everyday meals.
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.
