THE DETAILS: Researchers followed about 2,500 people ages 21 to 65 for a year, breaking them up into three groups: All visited a website with general health advice, but the second and third groups accessed a website that helped them track their diets and was tailored to their dietary needs and preferences. The third group also received individualized counseling by email. The researchers found a significant increase in the fruits and vegetables eaten, particularly among the branch of participants that also received motivational emails.
WHAT IT MEANS: Fruits and vegetables are nutritional superstars because they offer a wide variety of nutrients, in addition to disease-fighting phytochemicals. And accumulating evidence is linking produce to protection from certain cancers and other chronic diseases. But it can be hard to include enough healthy food in your diet when you're constantly tempted by fast-food fare and other heavily marketed, unhealthy choices. This study suggests that online tools can help you keep track of what you eat so that you can see where your diet falls short and can make changes accordingly. Just don't spend too much time at the computer, since exercise is another lifestyle factor that can cut your risk of health problems.
Here's how to use technology to help you eat a more healthful diet:
• Figure out what you need. There are several recommendations for how many fruits and vegetables you should eat each day, with the U.S. Department of Health and Human Services calling for men to eat nine servings a day, and women, seven. To get a more precise estimate, visit the U.S. Centers for Disease Control and Prevention's Fruits and Veggies Matter site to figure out how much produce you should eat each day, based on your age, sex, and activity level.

• Don't let it be boring. If you or your family members are getting bored with the typical produce lineup, try out some of these tips from Christine Gerbstadt, MD, RD, spokesperson American Dietetic Association:
1. If you've had a long day and can't deal with chopping, washing, and preparing vegetables, buy them frozen or fresh, already washed, and cut-up. Add them to any- and everything possible, such as soups, slow-cooker meals, black beans, chicken or vegetable stock, salads, or rice.
3. Plan a dinner around a fresh local vegetable, such as artichokes, asparagus, eggplant, acorn squash, or whatever's in season at a local farmer's market. Try stuffing it, breading and sautéing, or adding a dipping sauce. Check the Rodale Recipe Finder for cooking ideas.
4. Fresh salsas are a great way to include not just tomatoes, but also peppers, cucumbers, onion and leeks, fresh herbs, jicama, and root vegetables like parsnips, and carrots. Dip with corn chips or vegetable chips.
6. Dried beans and peas are vegetables, too. Cook them, puree, and season with new spice combinations, using cumin, turmeric, mint, basil, garlic, and oregano, and you've got a great spread to enjoy on a warm pita.
• Pick greener produce. When shopping for produce, try to buy organic whenever possible. Organic growing methods keep harmful hormone-disrupting chemicals out of your body, the soil, and water—and add greenhouse-gas carbon to the soil instead of the atmosphere.
