We are often at a loss of what to say when asked about the health of our vegetables, "of course it's healthy, it's a fresh vegetable." It turns out this isn't far from the truth. According to the CDC, "...vegetables contain essential vitamins, minerals, and fiber that may help protect you from chronic diseases. Compared with people who consume a diet with only small amounts of fruits and vegetables, those who eat more generous amounts as part of a healthful diet are likely to have reduced risk of chronic diseases, including stroke and perhaps other cardiovascular diseases, and certain cancers."
If your concern is weight loss, it's worth noting that Weight Watchers has given fruits and vegetables as strong of an endorsement as it can by giving all but the starchiest vegetables (potatoes, sunchokes, etc.) a point value of 0. Saying, in effect, that all calories are not created equal, as far as your body is concerned.
That said, we don't really think about the health benefits of our produce. We are concerned with taste. Eating our vegetables is an enjoyable experience, the health benefits are just the icing.
