adminvegetables and, as it turns out, they protect us too. Some act as antioxidants, mopping up unstable “free radical” molecules that can damage cells and lead to the development of heart disease, cancer, Alzheimer’s and other health issues. Others work by boosting the immune system.
What’s fascinating is that nature seems to have a way of highlighting these beneficial nutrients by giving them bright colours that allow you to spot them at a glance. For example, anthocyanins make blueberries blue and may help to keep your mind sharp. Tomatoes get their ruby hue from lycopene, a phytochemical that may help to prevent prostate cancer.
To get the maximum disease-fighting power that phytochemicals can provide, choose foods that represent all colours of the rainbow.
The USDA suggests paying particular attention to orange and red (5 1/2 cups per week) and dark green (1 1/2 cups per week) produce, both good sources of vitamin A and other important nutrients.
Red foods, such as tomatoes and watermelon, contain lycopene, a phytochemical that may help protect against prostate and breast cancers.

Alpha and beta carotene make foods like carrots and sweet potatoes so brilliantly orange. The body converts these compounds into the active form of vitamin A, which helps keep your eyes, bones and immune system healthy. These phytochemicals also operate as antioxidants, sweeping up disease-promoting free radicals. —www.food.com.
