Many people have heard that lycopene is beneficial for preventing prostate cancer, and broccoli is also a well-known anti-cancer vegetable. What happens if you eat these two vegetables together? A study published in the prestigious academic journal "Cancer Research" conducted an experiment on this.
Researchers used rats for the experiment, transplanting them with prostate cancer cells and then feeding them different diets. Some were fed a diet containing 10% broccoli powder and 10% tomato powder, some were fed only one of the two, some were fed isolated lycopene, and others were fed a standard diet. After 22 weeks, the group fed tomato powder and broccoli powder showed the best cancer-inhibiting effect, with a 52% reduction in tumor weight; the broccoli powder group showed a 42% reduction, the tomato powder group a 34%, and the isolated lycopene group only a 7% reduction.
The experiment tells us that the various components in vegetables are beneficial to health, and eating whole vegetables is much more effective for health benefits than consuming isolated components. The combined effect of various health components is better than consuming just one type of health component. Researchers speculate that this might be because different health components (such as lycopene, flavonoids, anthocyanins, and glucosinolates) inhibit cancer cells through different pathways, and they may have a synergistic effect.
It seems that to get the health benefits of vegetables, one should consume a wide variety of vegetables, especially those with deep colors, as they are the varieties richest in health-promoting and nutritional components. Deep red vegetables contain lycopene, purplish-red and purplish-black vegetables contain anthocyanins, orange or yellow vegetables contain carotenoids, and green vegetables are rich in carotenoids and flavonoids. Regularly eating a variety of colorful vegetables is beneficial for preventing cancer and many chronic diseases.
At the same time, the quantity of vegetable intake is also very important. Eating a small amount of vegetables is not enough to fully obtain their health effects. To account for 10% of the diet, one needs to consume 500-1000 grams of vegetables daily, and remember that it is best if more than half of these are dark green, red, or orange vegetables. Remember that vegetables should be cooked lightly; vegetables that are soaked in oil, stir-fried until burnt, or charred have no anti-cancer effect.
Ways to increase vegetable intake
It's difficult to eat a large amount of vegetables for breakfast, so consider drinking a large glass of vegetable juice.
Lunch can include a fair amount of vegetables, but the variety is often limited, so prioritize eating leafy green vegetables.
Use vegetables as snacks between meals, such as tomatoes, cherry tomatoes, cucumbers, and radishes.
