THURSDAY, Nov. 12 (HealthDay News) -- Wireless phones have a biological effect on the brain, but it's too early to say whether this poses any health risks, a Swedish medical researcher reports.
Fredrik Soderqvist, of Orebro University, analyzed blood samples from adult wireless phone users and discovered they had elevated levels of a protein called transthyretin, which is found in the blood-cerebrospinal fluid barrier that protects the brain against harmful substances in the blood system.
The findings indicate that the brain is affected by microwaves from cell phones and other wireless telephones, which may cause other as yet unknown effects, said Soderqvist, who conducted the research as part of his doctoral thesis.
He recommended caution in the use of wireless phones, especially among children and teens.
"Children may be more sensitive than adults to radiation from wireless phones," Soderqvist said in a news release from the university.
As part of his thesis, he surveyed wireless phone users about self-reported health problems and found that children and teens who regularly use the devices experienced more health problems and rated their well-being lower than those who didn't regularly use wireless phones.
"The connection was strongest regarding headaches, asthmatic complaints, and impaired concentration," Soderqvist said. "But more research is needed to exclude the effects of other factors and sources of error, even though it is difficult to see how this connection could be fully explained by such factors."
He said the findings are cause for concern, since so many children and teens use wireless phones and "the possible health effects from long-term exposure to microwaves have not been clarified, especially among children and adolescents."
Soderqvist noted that the "threshold [safety] values in place today protect us from warming, a so-called thermal effect. But if there are mechanisms that are independent of warming, it is not certain that today's thresholds provide protection. And it may be that these are effects that will not be perceived until later on in the future."

We live in a fast paced world where food is often consumed while driving down the highway over the speed limit and watching for police vehicles. Fast food restaurants have figured this out and are stepping up to the challenge of providing healthier food to all of the patrons that go whizzing by their drive up service windows.
Panera Bread came in first place for their comprehensive menu offering multiple healthy choices for every meal. Panera Bread also received top honors for their kids menu.
Jason’s Deli, located in the Midwest, came in second. This particular deli has a penchant for organic foods and with this in mind, approximately one fifth of all of its ingredients are organic.
Third place belongs to Au Bon Pain, which has been a pioneer in the idea of healthy fast foods. They serve sandwiches, soups, salads and even hot entrees made with whole grains, veggies and even hormone free chicken.
Noodles and Company doesn’t sound like a name you would expect to make it in a top ten healthy fast food list however this Asian food court eatery makes healthy its business, cutting out all the grease and using soybean oil in their cooking. Which puts them in fourth place.
Corner Bakery Café is a Midwest, Mid-Atlantic, and Southern based café that has a breakfast menu full of healthy choices. It also has healthy salads, sandwiches and soups. They use whole grains, lean meats and vegetables. They also practice portion control. They land solidly in fifth place.
Chipotle takes sixth place followed by Atlantic Bread and McDonald’s takes a surprising 8th place. Einstein Bagels takes ninth place followed by Taco Del Mar. That rounds out the top ten. As with any menu, you will find more and less healthy items in every location.

* Focus on whole, plant-based foods. Fill most of your plate with fruits and leafy green vegetables. Also include a variety of whole grains, beans, and legumes to give you filling fiber and keep you going throughout the day. Try to find minimally-processed or locally-grown foods whenever possible and make these foods the mainstay of your diet.
* Bone up on calcium. Women are at a greater risk than men of developing osteoporosis, so it’s important to get plenty of calcium to support your bone health. While dairy products are high in calcium, their animal fat and protein can accelerate bone loss. So also consider plant-based sources of calcium like beans, broccoli, kale, Brussels sprouts, and collard greens.
* Don’t eat too much protein. Protein is an essential part of any healthy diet, but eating too much animal-based protein—such as the levels recommended in many low-carb, high-protein diets—is particularly dangerous for women. Eating lots of protein causes calcium loss. Over time, this could lead to a decrease in bone density and osteoporosis.
* Make sure you get enough iron. Many women don’t get enough iron in their diet. On top of that, women lose a lot of this important mineral during menstruation. Boost your intake by eating iron-rich foods such as lean red meat, dark poultry, lentils, spinach, almonds, and iron-fortified cereals.
* Cut back on alcohol and caffeine. Women who have more than two alcoholic drinks a day are at higher risk of osteoporosis. Caffeine consumption interferes with hormone levels and also increases the loss of calcium. Try to limit alcohol consumption to one glass a day and caffeine to one cup a day.

Make careful menu selections – pay attention to the descriptions on the menu. Dishes labeled deep-fried, pan-fried, basted, batter-dipped, breaded, creamy, crispy, scalloped, Alfredo, au gratin or in cream sauce are usually high in calories, unhealthy fats or sodium. Order items with more vegetables and choose leaner meats.
Drink water with your meal. Soda is a huge source of hidden calories. One 32-oz Big Gulp with regular cola packs about 425 calories, so one Big Gulp can quickly gulp up a big portion of your daily calorie intake. Try adding a little lemon to your water or ordering unsweetened iced tea.
“Undress” your food. When choosing items, be aware of calorie- and fat-packed salad dressings, spreads, cheese, sour cream, etc. For example, ask for a grilled chicken sandwich without the mayonnaise. You can ask for a packet of ketchup or mustard and add it yourself, controlling how much you put on your sandwich.
Don't be afraid to special order. Many menu items would be healthy if it weren't for the way they were prepared. Ask for your vegetables and main dishes to be served without the sauces. Ask for olive oil and vinegar for your salads or order the dressing "on the side" and spoon only a small amount on at a time. If your food is fried or cooked in oil or butter, ask to have it broiled or steamed.
Watch portion size - an average fast food meal can run as high as 1000 calories or more, so choose a smaller portion size, order a side salad instead of fries, and don't supersize anything. At a typical restaurant, a single serving provides enough for two meals. Take half home or divide the portion with a dining partner. Sharing might make dessert (or something else indulgent) more of an option.
Watch your salt. Fast food restaurant food tends to be very high in sodium, a major contributor to high blood pressure. Don’t add insult to injury by adding more salt.
Avoid buffets – even seemingly healthy ones like salad bars. You'll likely overeat to get your money's worth. If you do choose buffet dining, opt for fresh fruits, salads with olive oil & vinegar or low-fat dressings, broiled entrees and steamed vegetables. Resist the temptation to go for seconds, or wait at least 20 minutes after eating to make sure you're really still hungry before going back for more.
Eat mindfully. Pay attention to what you eat and savor each bite. Chew your food more thoroughly and avoid eating on the run. Being mindful also means stopping before you are full. It takes time for our bodies to register that we have eaten. Mindful eating relaxes you, so you digest better, and makes you feel more satisfied.
Remember the big picture – Think of eating out in the context of your whole diet. If it is a special occasion, or you know you want to order your favorite meal at a nice restaurant, make sure your earlier meals that day are extra healthy. Moderation is always key, but planning ahead can help you relax and enjoy your dining out experience while maintaining good nutrition and diet control.
