Study IDs key protein for cell death

When cells suffer too much DNA damage, they are usually forced to undergo programmed cell death, or apoptosis. However, cancer cells often ignore these signals, flourishing even after chemotherapy drugs have ravaged their DNA. A new finding from MIT researchers may offer a way to overcome that resistance: The team has identified a key protein involved in an alternative death pathway known as programmed necrosis. …

Your 5 worst gluten-free mistakes

After experiencing some wacky symptoms, I was recently tested for celiac disease, and while the report came back negative, I've noticed that I do feel better when I avoid gluten. Many of my clients are in the same boat, but others seek me out after going gluten free and feeling worse, or even gaining weight, which seems to be increasingly common.  The truth is, navigating the gluten-free landscape can be pretty darn tricky. Here are five common missteps I see, and how to resolve them. Not 'getting' gluten One client recently said to me, “I'm not really sure what gluten is, but I know it's bad, right?” I think a lot of people are a little in the dark about the issue at large, and it is complicated, but in a nutshell, here's what you need to know: gluten is a type of protein naturally found in wheat (including spelt, kamut, farro, and bulgur) and other grains, like barley and rye. In people who have celiac disease, consuming even small amounts of gluten triggers unwelcome symptoms, including belly pain and bloating. This happens because gluten causes the immune system to damage or destroy villi, the tiny, fingerlike structures that line the small intestine like a microscopic plush carpet. Healthy villi absorb nutrients through the intestinal wall into the bloodstream, so when they become damaged, chronic malnutrition occurs, which is typically accompanied by weight loss and exhaustion. Other symptoms may include bone or joint pain, depression, and skin problems. In people with this diagnosis, the only way to reverse the damage, and the accompanying symptoms, is to completely avoid gluten. People like me, who test negative for celiac disease, may be experiencing a condition called gluten intolerance, or gluten sensitivity, which means that while not celiac, consuming gluten causes bothersome side effects, which can include flu-like feelings, bloating, and other gastrointestinal problems, mental fogginess, and fatigue. Unfortunately, there is no real test for gluten sensitivity at this time, and the symptoms may be related to other issues, including stress (who doesn't have that?!), which makes it a not-so-black-and-white issue. Health.com: Will a Gluten-Free Diet Improve Your Health? Confusing 'gluten free' with 'wheat free' or refined grains As I noted above, gluten isn't only found in wheat. I've heard numerous people say they eat gluten free, but all they've really done is replace foods like white bread with hearty whole grain versions, which may include spelt (in the wheat family), and rye (which, while not wheat, also contains gluten). If you don't have celiac disease or gluten intolerance, these swaps may make you feel great, and lead to weight loss, because trading refined grains for whole grains ups your intake of <a href=”http://www.health.com/health/gallery/0,,20553010,00.html”>fiber</a>, boosts satiety, so you feel fuller longer, and better regulates blood sugar and insulin levels. These are all good things, but, in this case, totally unrelated to gluten. Health.com: 15 Gluten-Free Recipes Thinking gluten free equals weight loss You may have seen a friend, co-worker, or celebrity suddenly slim down after proclaiming to give up gluten. And while going gluten free may absolutely lead to dropping a dress size (or more), the weight loss is generally caused by giving up foods that contain gluten, which are loaded with dense amounts of refined carbs, like bagels, pasta, crackers, pretzels, and baked goods. Axing these foods altogether, or replaced them with more veggies and healthy gluten-free whole grains, like quinoa and wild rice, automatically cuts excess carbs (which may have been feeding fat cells), ups fiber and nutrients, and results in soaring energy. However, going gluten free can also lead to weight gain. Health.com: Best Superfoods for Weight Loss Loading up on gluten-free junk food Because gluten free has exploded in popularity, there are dozens of gluten-free options in markets these days, including carb-laden (but gluten free) versions of… bagels, pasta, crackers, pretzels, and baked goods! One popular brand of gluten free cookies pack 60 calories each, more than a “regular” sandwich cookie. And some gluten-free foods are made with refined gluten-free grains, which have been stripped of their fiber and nutrients, like white rice. The bottom line is, simply going gluten free doesn't guarantee the loss of pounds and inches—quality and quantity still matter most. Health.com: Are You Making These Dieting Mistakes? Ignoring the rest of your diet In addition to quality and quantity, balance is critical for feeling well and achieving weight loss. I've seen people trade white pasta for healthy whole grains like quinoa or wild rice, but still eat portions that are far too large, and therefore not see weight loss results. Others believe it's OK to eat unlimited amounts of healthy gluten-free foods, like fruit and nuts. But sadly, any time you eat more than your body can use or burn, even from healthy foods, you create surpluses, which get shuttled straight to your body's storage units—fat cells. If you have celiac disease (get tested if you suspect you do, but you're not sure), you absolutely must avoid gluten, and it's important to note that it lurks in many products, from salad dressings and seasoning mixes, to vitamins, and even lip balm, so eliminating it completely is a big commitment. And if you think you may be gluten intolerant, try to avoid gluten, and monitor your how you feel. But in either case, the single most important thing you can do is to strive for a healthy, balanced, whole foods diet, the true keys to both optimal health and weight loss.

Tumor-activated protein promotes cancer spread

The findings are published in this week’s online Early Edition of the Proceedings of the National Academy of Sciences. Roughly 90 percent of all cancer deaths are due to metastasis — the disease spreading from the original tumor site to multiple, distant tissues and finally overwhelming the patient’s body. Lymph vessels are often the path of transmission, with circulating tumor cells lodging in the lymph nodes — organs distributed throughout the body that act as immune system garrisons and traps for pathogens and foreign particles. The researchers, led by principal investigator Judith A. …

200 reported sick in salmonella outbreak

The owner of a Las Vegas eatery at the center of a Salmonella outbreak said Friday he does not plan to reopen the restaurant at its current location. Firefly restaurant owner John Simmons said in a statement that he will move forward with plans to move the eatery from 3900 Paradise Road to 3824 Paradise by the end of the month. “We are optimistic that the combination of moving to this new location that has a kitchen as large as the entire original Firefly restaurant and the recommended retraining on operations and procedures will help us regain the confidence of the community,” Simmons said in a statement released Friday. Simmons' announcement came shortly after health officials updated the number of people affected in the Salmonella outbreak to 200. The Southern Nevada Health District released the updated number as part of a second interim report in the health inspection of Firefly restaurant on Paradise Road. An initial report put the number of people affected by the outbreak to 89. The new number comprises 196 patrons and four employees. SNHD said the people stricken with foodborne illness dined at the restaurant during a period of time including April 21-26. Health inspectors cited the restaurant for 44 demerits connected to improperly stored food in inadequate temperatures, according to the report.

France confirms 2nd case of SARS-related virus

PARIS – & The French Health Ministry says a second case of a deadly new respiratory virus related to SARS has been confirmed. A ministry statement issued Sunday said a hospital roommate of the 65-year-old man who initially contracted the virus has tested positive. The two shared a room for a few days in late April at Valenciennes hospital in northern France, and hence were in “prolonged and close contact.” Both are now hospitalized in nearby Lille. Four suspected cases, all people who had contact with the initial patient, were false alarms. The novel coronavirus has killed 18 people since being identified last year in the Middle East, out of 30 confirmed cases reported to the World Health Organization since September 2012. The first France patient had just returned from vacationing in Dubai.source : http://www.foxnews.com/health/2013/05/12/france-confirms-2nd-case-sars-related-virus/

The surprising reason you snack at night — and how to stop it

Over the years, many of my clients on quests to eat healthier and lose weight have told me, “I do great all day, but at night, everything just seems to fall apart.” Sometimes this happens because evening hours are less busy and structured, or because we create patterns that once formed are difficult to break, like nibbling while cooking, or always eating a sweet treat after dinner. But now, new research shows that our bodies may be physiologically programmed to crave cookies after dark. A study in the journal Obesity concludes that our internal clock, the circadian system, prompts us to reach for sweet, starchy, and salty foods in the evenings, especially around 8:00 p.m. Throughout history, this built-in need to feed may have helped our ancestors store fat to survive when food was scarce, but today, it can take a hefty toll on your health and your waistline. So, how do you fight it? Here are six tips to prevent going overboard in the evening. Connect the dots For many people, eating in general, regardless of what time, tends to be mindless. But when you start thinking about food as fuel for activity, it can help bring the importance of quality and balance into focus. In a nutshell, the fate of a meal or snack depends on what's going in your body during your post-noshing hours. Eating the bulk of your food in the evening, when your activity level is low, results in winding up with far more fuel than you body needs, and the surplus gets sent straight to your fat cells. Your body also does the bulk of its maintenance, healing, and repair work while you sleep, so the quality of the food you eat close to bedtime is key. Processed junk won't provide the building blocks that go to work to build muscle tissue, maintain a healthy immune system, and keep your skin looking radiant. Health.com: Best Superfoods for Weight Loss Break associations If your nightly routine involves eating more than you'd like, consciously break the pattern. Just changing the order of your evening activities can help. For example, if you tend to munch while going through your mail, as you stand in the kitchen, sort it in the bedroom instead. If you tend to grab snacks during TV commercials, use those breaks to get small tasks done—fold laundry, iron, pick out your clothes for work the next day, load or unload the dishwasher, or groom your pet. Simply breaking the connections between certain activities and eating can help your brain let go of the notion that it doesn't feel “right” not to follow through. Setting up new routines may seem forced or awkward at first, but before long, the healthier pattern will become your new normal. Health.com: 16 Ways to Lose Weight Fast Pre-plan meals If you're worn out after a long day, thinking about what to make for dinner can feel like a burden, or at the very least a chore. Without healthy options in place, it's so easy to order take out, make a meal out of less than optimal snacks, or reach for comfort foods. But putting healthy options in place doesn't have to be a time suck. If you don't feel like being creative, keep the ingredients for a few quick go-to meals on hand, so you can whip them up in a jiffy. One of my favorite quickies is a simple lentil salad. I always keep my fridge stocked with organic greens, and steamed vacuum-sealed lentils (you can find these in the produce section). I simply toss the greens with balsamic vinegar, add a scoop of lentils, sprinkle with sliced almonds, and pair with a serving of 100 percent whole grain crackers (or crush them on top). While not as fancy as my usual fare, within minutes, dinner is done, and far more nourishing and satisfying than a frozen entrée or bowl of cereal. Health.com: 30 Quick-and-Easy Fat-Burning Recipes Keep a journal I know, I know, you've heard this a million times, but it's one of those tried and true tools that just works. One recent study found that women who kept food diaries lost about six more pounds than those who did not. Another discovered that keeping a food diary doubled weight loss results. If you've been overestimating your body's needs, underestimating how much you eat, and engaging in a lot of mindless eating (three common missteps), journaling will keep you aware and honest, and can allow you to identify unhealthy patterns, which is the first step to changing them. Set yourself up for sleep Staying up late, during the hours you should be sleeping, increases the odds of overeating at night. And numerous studies over the past few years have connected a lack of adequate sleep to weight gain. Prior to the invention of the light bulb (not to mention TVs, smart phones, and laptops), we slept about 10 hours a night. Today, Americans average 6.9 hours of sleep on weeknights and 7.5 hours on weekends. Health.com: 7 Tips for the Best Sleep Ever Believe you can If you believe you can change your habits and routines, you will. It sounds oversimplified, but that's the conclusion of a recent study that analyzed data on the diet, exercise, and personality types of over 7,000 people. Those who believed they have the ability to change their lives through their own actions tended to eat healthier, exercise more, smoke less, and avoid binge drinking. When I have clients say things like, “I'll never be able to change” I ask them to name something else they changed or achieved that they felt doubtful about, but ultimately accomplished. Reminding yourself of your past successes can help you feel more confident about your ability to transform your lifestyle. If you need support, reach out for it. Friends, family members, co-workers, or even an online community to connect to can help immensely, especially during those moments when you just want to fall back into your old (unhealthy) comfortable routines!
