Watermelon
No other fruit says summer like the subtly crunchy, thirst quenching watermelon. Although watermelons can now be found in the markets throughout the year, the season for watermelon is in the summer when they are sweet and of the best quality.But watermelon is not only great on a hot summer day, this delectable thirst-quencher may also help quench the inflammation that contributes to conditions like asthma, atherosclerosis, diabetes, colon cancer, and arthritis.
Sweet, juicy watermelon is actually packed with some of the most important antioxidants in nature. Watermelon is an excellent source of vitamin C, rich in the B vitamins necessary for energy production and a very good source of vitamin A, notably through its concentration of beta-carotene. Watermelon is also a source of the potent carotenoid antioxidant, lycopene. These powerful antioxidants travel through the body neutralizing free radicals.
In contrast to many other food phytonutrients, whose effects have only been studied in animals, lycopene has been repeatedly studied in humans and found to be protective against a growing list of cancers. These cancers now include prostate cancer, breast cancer, endometrial cancer, lung cancer and colorectal cancers.
Yummy Watermelon!

Question of the Day: Are colored potatoes healthier than white potatoes?
Are colored potatoes healthier than white potatoes?The differences in color between varieties of potatoes are basically differences in carotenoid and flavonoid content. Virtually all types of potatoes provide significant amounts of approximately seven to ten nutrients. While Americans are accustomed to potatoes with a white inside, potatoes in other parts of the world more commonly have starchy yellow insides.
All colorful potatoes provide carotenoids (and some also provide flavonoids) that white potatoes do not. Carotenoids and flavonoids are pigments, and according to nutritional research, they provide us with many health benefits, including cancer protection. For example, the darker the starchy yellow flesh of a yellow potato, the greater quantity of carotenoids, including beta-carotene (and, in some cases, lutein) that is present. The blue in blue potatoes comes from their flavonoid content. Both the flavonoids found in blue potatoes and the carotenoids found in yellow potatoes help promote good health!
Some carotenoid- and flavonoid-rich potatoes currently available in different regions of the U.S. include: Yukon Gold (currently the best-selling yellow potato in the U.S. marketplace), Michigold, Donna, All Blue (also called "Purple Marker"), Purple Viking, Saginaw Gold, Red Gold, Rose Gold, and Ruby Crescent.
The presence of carotenoids and flavonoids, however, does not affect the carbohydrate content of potatoes. Potatoes all contain about one gram of carbohydrate for every four calories—they're basically all-carbohydrate when it comes to calorie content.
Technically, you'll get more fiber and minerals per bite from smaller potatoes of any kind, since they have more surface area (skin) per amount of starchy inside (total volume). The three to seven grams of fiber contained in a medium-sized potato are mostly in the skin, so consider enjoying it as well as the potato's insides the next time you cook some spuds. Of course, unless your potato is an organically grown one, you'll be getting most of the pesticide residue here—in the skin—as well, which is one of the reasons I am a big advocate for purchasing potatoes (and other foods) that are organically grown. Although there are some differences among potatoes, if you are seriously looking to lower carbohydrate intake, you need to switch to a different category of vegetable, like the leafy green vegetables.

One Potato....Two Potato... SWEET POTATO!
A nutritional All-Star — one of the best vegetables you can eat. They're loaded with carotenoids, vitamin C, potassium, and fiber. Bake and then mix in some unsweetened applesauce or crushed pineapple for extra moisture and sweetness.Labels: carotenoids, healthy diet, potassium, Sweet potato, vegetable
