Please pass the cruciferous vegetables. This vegetable family includes kale, cauliflower, broccoli, and brussels sprouts. You might already be familiar with their ability to fight cancer. But cruciferous veggies, as well as dark-green leafy and deep-yellow orange vegetables, may also have a protective role with other diseases, such as cataracts, heart disease and stroke. Try to include this group of vegetables in your diet at least two to three times per week. They are best when raw or lightly cooked.
