Even if you've never heard of phytonutrients, chances are you eat them every day. And chances are that you probably should eat more of them. That's because phytonutrients are the organic compounds found in plants that are believed to enhance and promote wellness.
There are many different classes of phytonutrients, some of which scientists know more about than others. But evidence is mounting that they all offer protection against disease and can be a key factor in achieving and maintaining good health. How do you get a good dose of phytonutrients? Eat colorfully!
Think dark, juicy cherries and pomegranates, tart cranberries, luscious grapes, tangy peppers and tomatoes, and sweet beets.
Why to eat it: The red color group, which includes red potatoes and onions as well as rhubarb and watermelon, is a well-spring of the carotenoid known as lycopene. Eating plenty of red foods such as these can help ward off heart disease and cancer and prevent vision problems such as age-related macular degeneration (the leading cause of blindness in adults over 55).
Leafy salad greens are an obvious good choice, but don't overlook other vegetables and fruits. Great green foods include green beans, green peppers, broccoli, asparagus, avocado, green apples, limes, kiwis, grapes, and honeydew melons.
Why to eat it: Green produce is full of lutein, an antioxidant that's particularly good at helping prevent vision issues such as cataracts.
These cool-hued foods include blueberries, blackberries, plums, raisins, eggplants, purple cabbage, and purple potatoes.
Why to eat it: You can thank anthocyanins, potent antioxidants that have been found to tamp down inflammation and stave off the growth of cancer cells, for the beautiful hue. The nutrient may also help boost memory and prevent cognitive deficits as people age.
Brightly colored foods, such as carrots, yellow peppers, mangoes, cantaloupes, apricots, papayas, peaches, pineapples, and sweet potatoes top this list.
Why to eat it: These sunny picks are loaded with immune-boosting vitamin C and other antioxidants. Look for produce that's deeply colored—it contains higher levels of nutrients.
Although perhaps not as beautiful as their rainbow-hued brethren, earth-colored foods have plenty of health benefits to offer.
Why to eat it: Mushrooms are high in selenium, a mineral that may contribute to heart health and reduced cancer risk, while garlic and onions contain allicin, an antibacterial compound. Don't neglect such high-fiber goodies as bananas, pears, cauliflower, and white corn when you hit the grocery store.

GettyThis week, I picked up both eggplant and shallots at the farmer's market. While searching for ways to cook the eggplant (I'm very bad at eggplant), I came a recipe for eggplant and shallot stew, which sounded so good I wanted to make it immediately. Of course, I was missing almost all ingredients aside from shallots and eggplant, for the recipe (from Eating Well magazine), so here is my own riff on it (à la raisins, cashews and whole-wheat couscous, and minus what sound like complicated spice-grinding and mustard-seed-popping processes).
CorbisHere's a simple thing you can do to tune up your metabolism for summer: have a protein shake each day for breakfast. Choose to do this over cereal or a bagel and you will enjoy better appetite control, increased fat burning and blood sugar balance to avoid cravings all day long. When making your breakfast power treat, consider these super foods or supplements to enhance its therapeutic effects:

Erik S. Lesser / APWe're all aware that childhood obesity has become an epidemic in the United States. But how far should we go to make sure that children are making the right lifestyle choices? A controversial piece in the Journal of the American Medical Association suggested that extremely obese children be put into temporary foster care.

When 7-Eleven Inc. celebrates its birthday, the convenience store gives away free Slurpees to customers! 7-Eleven turrned 84 a week and a half ago (7/11/11), and while the company has been giving away Slurpees annually since 2002, this year's event was anticipated to be larger than ever.

GettyIn reasonable doses, sunlight enables natural immunity, promotes skin growth and healing, stimulates our "happy" hormone (serotonin) and contributes to an overall sense of well-being. Getting some sunlight for 15 or 20 minutes a day enables the body to manufacture Vitamin D and is responsible for the synthesis of the pigment melanin, the skin's natural sunscreen.
GettyAnyone who's sought solace in pizza or a pint of ice cream knows that food can be comforting. But experts still don't know exactly why we gravitate toward fatty or sugary foods when we're feeling down, or how those foods affect our emotions.
GettyHow spontaneous or neurotic you are could dictate how much you weigh, says a new study.

Tim Sloan, AP/Getty ImagesThe nation's annual obesity report was released on Thursday with bleak news: In 2010, 12 states had obesity rates above 30 percent, most of them located in the southern U.S. As recently as 2006, only one state was above the 30-percent-mark: Mississippi. Mississippi again came in as the nation's heaviest state, for the seventh year in a row, with Alabama, Louisiana, Tennessee and West Virginia close behind. And more bad news: no state decreased its obesity rate since the 2009 report, though only 16 states showed increases (down from 28 increases a year ago).
GettyA new study has found that only 1 out of 6 diners pay attention to posted nutrition information on menus -- and while some is better than none, the reality is that the each meal eaten outside of the home tacks on an average of 134 calories to your day.
GettyOver the last few months there has been a lot of talk about the best diet. (Check out U.S. News' evaluation of 20 popular diets, for instance -- the DASH diet came out on top.) But what about those diets that didn't make the cut ... by a longshot?

Christopher Furlong, Getty ImagesAs I stood in line to pay for my tall, decaf, non-fat, extra-hot mocha the other day at Starbucks, I was tempted by an orange-cranberry scone in the pastry case that seemed to be staring at me. "How bad can a scone be?" I wondered. "It's not like it's one of those glazed apple fritters or oversized blueberry muffins in there," I rationalized. But before I could make up my mind, the perky Starbucks girl was asking for my debit card. Lucky for me; when I got home, I decided to research that beckoning scone, and it turns out, it has a whopping 490 calories and 18 grams of fat. Crisis averted.
