New Treatments for Severe Food Allergies


This is good news for treating kids with allergies. These new approaches can help every family in long way.

 

What is food allergy?

Food allergy is an abnormal response to a food, triggered by the body’s immune system. There are several types of immune responses to food. The information on this Web site focuses on one type of adverse reaction to food, in which the body produces a specific type of antibody, called immunoglobulin E (IgE).

The binding of IgE antibodies to specific molecules in a food triggers the immune response
The response may be mild, or in rare cases it can be associated with the severe and life-threatening reaction called anaphylaxis.
If you have a food allergy, it is extremely important for you to work with your healthcare professional to learn what foods cause your allergic reaction
Sometimes, a reaction to food is not an allergy at all but another type of reaction called food intolerance.

What are new treatments?

1. The first treatment involves oral immunotherapy, a type of allergy management that involves desensitization.
2. This approach is being tested at the Northwest Asthma and Allergy Center (NAAC) in Seattle. Researchers at the NAAC have experimented with a skin patch containing a small amount of known food allergen’s proteins

Allergies caused by foods can be not only bothersome, they can be fatal. This fact makes two new breakthrough treatments for children with severe food allergies a breath of fresh air for parents and researchers hoping to save the lives of their children who suffer from extreme allergic reactions to certain types of foods. The new treatments focus on desensitizing children to foods that cause extreme allergic reactions. The significance of food allergies is not a trite matter. In fact, experts see a parallel between food allergies and the sharp rise of other recent epidemics such as asthma, diabetes and autoimmune diseases. There is no rational explanation for the growth of these diseases, but they continue to afflict millions of Americans.
  According to NBC News Chief Medical Editor, Dr. Nancy Snyderman, while there is no true cure for food allergies in children, the new research offers hope for experts who want to stop the deadly reactions associated with allergies. Snyderman explained that researcher’s estimate that nearly 15 million Americans have food allergies, and that potentially deadly reaction to food allergies affects nearly six million children under the age of 18 throughout the United States each year. The new research shows a glimmer of hope in curbing deaths causes by food allergies. The hope is that allergies can now be managed so that they are not deadly.
The American College of Allergy, Asthma and Immunology (ACAAI) reported that food-related allergies are caused by a number of foods. However, the most common foods known to trigger severe allergic reactions are well-known. Peanuts and cow’s milk top the list of foods most likely to cause allergies in children. Other foods include eggs, tree nuts, wheat and soy, and shellfish. Experts explain an allergic reaction starts with an ordinary food, like a peanut. The protein within a peanut is misidentified in the body as an invader, like a virus or bad bacteria. The body immediately starts to create a defense for the invader.

 This sets off a fire hydrant-like release of chemicals into the bloodstream, including histamines. Those chemicals trigger the release of more chemicals, and the chemical chain reaction escalates in a sustained loop. This ever-increasing chemical chain reaction escalates in a sustained loop. This ever-increasing chemical cascade continues until the heart or the lungs to fail, and the person collapses. This is called anaphylactic shock and it can be deadly. Finding a cure, therefore, becomes a critical focus for researchers who are hopeful new treatments will save lives of children with severe food allergies. Finding a new treatment for severe food allergies will not only save lives, it will save money as well. According to American Journal of the American Medical Association’s (JAMA) researcher, Dr. Ruchi Gupta, the overall economic cost in pediatric food allergy was estimated at just under $25 billion a year. That equates to approximately $5,000 for every child afflicted with allergies across the United States. This figure includes medical costs, clinician visits, emergency department visits, and even hospitalization, explained Gupta. She further stated, “Childhood food allergy results in significant medical costs for our health care system but even larger costs for families.” The new approach to helping find a cure for food related allergies in children involves two different types of treatments. The first treatment involves oral immunotherapy, a type of allergy management that involves desensitization. According to New York Times reporter, Melanie Thernstrom, the revolutionary new treatment helps children re-educate their over active immune systems by feeding them very small doses of allergy causing foods, gradually increasing the amounts over the course of several months. In addition to the allergy causing foods, patients are injected with the asthma drug Xolair.

“Eventually patients build up their tolerance for the food until it is no longer dangerous,” said Stanford University Allergy Center Director, Dr. Kari Nadeau, who heads up the study on oral immunotherapy. The results of Nadeau’s research has shown remarkable results in childhood patients who suffer from food allergies. After six months of treatment, many children have become desensitized to the foods that used to send them to the hospital. Still Nadeau explained that the treatment is not a complete solution for children suffering from food-related allergies. “Oral immunotherapy is still experimental. Patients are not cured, they are desensitized enough that they can tolerate their former allergens,” said Nadeau.

The second approach is being tested at the Northwest Asthma and Allergy Center (NAAC) in Seattle. Researchers at the NAAC have experimented with a skin patch containing a small amount of known food allergen’s proteins. Because peanuts are one of the most common forms of foods children are allergic to, and because reaction to peanuts can often times be life threatening, the initial research at the Seattle-based NAAC focused on the legume. According to Dr. Stephen Tilles, as the protein-tainted patch is absorbed into the skin, it provides a form of immunotherapy. “The goal is to achieve the same type of results as a vaccination,” said Dr. Tilles. Whether it is peanuts or cashews, milk or eggs, shrimp or fish, severe food allergies among children is a growing concern among doctors who are searching for new food allergy treatments that will save lives and create a better life for children. While these two experiments have shown great promise to reduce food-related allergies among children, they are still both in the early stages of experimentation, and awaiting FDA approval.

Why eating sugar is even bad for healthy peoples (Many fatal heart problems)?

0 comments

Why eating Sugar is bad?

This new study suggests why eating too much sugar is bad for everyone.  Sometimes we think we are not eating any sugar directly but there many hidden sources in our daily life foods.

FunnyPart-com-how_much_sugar.jpg

Could too much sugar be deadly? The biggest study of its kind suggests the answer is yes, at least when it comes to fatal heart problems. It doesn't take all that much extra sugar, hidden in many processed foods, to substantially raise the risk, the researchers found, and most Americans eat more than the safest amount. Having a cinnamon roll with your morning coffee, a super-sized sugary soda at lunch and a scoop of ice cream


... sugar red bull and coffee on monday morning crazy kitty cat too funny

after dinner would put you in the highest risk category in the study. That means your chance of dying prematurely from heart problems is nearly three times greater than for people who eat only foods with little added sugar.
For someone who normally eats 2,000 calories daily, even consuming two 12-ounce cans of soda substantially increases the risk. For most American adults, sodas and other sugary drinks are the main source of added sugar. Lead author Quanhe Yang of the U.S. Centers of Disease Control and Prevention called the results sobering and said it's the first nationally representative study to examine the issue.

less sugar more fruit

Scientists aren't certain exactly how sugar may contribute to deadly heart problems, but it has been shown to increase blood pressure and levels of unhealthy cholesterol and triglycerides; and also may increase signs of inflammation linked with heart disease, said Rachel Johnson, head of the American Heart Association's nutrition committee and a University of Vermont nutrition professor. Yang and colleagues analyzed national health surveys between 1988 and 2010 that included questions about people's diets. The authors used national death data to calculate risks of dying during 15 years of follow-up.
Overall, more than 30,000 American adults aged 44 on average were involved. Previous studies have linked diets high in sugar with increased risks for non-fatal heart problems, and with obesity, which can also lead to heart trouble. But in the new study, obesity didn't explain the link between sugary diets and death. That link was found even in normal-weight people who ate lots of added sugar. "Too much sugar does not just make us fat; it can also make us sick," said Laura Schmidt, a health policy specialist at the University of California, San Francisco. She wrote an editorial accompanying the study in Monday's JAMA Internal Medicine. The researchers focused on sugar added to processed foods or drinks, or sprinkled in coffee or cereal. Even foods that don't taste sweet have added sugar, including many brands of packaged bread, tomato sauce and salad dressing. Naturally occurring sugar, in fruit and some other foods, wasn't counted.

Most health experts agree that too much sugar isn't healthy, but there is no universal consensus on how much is too much. U.S government dietary guidelines issued in 2010 say "empty" calories including those from added sugars should account for no more than 15 percent of total daily calories. The average number of daily calories from added sugar among U.S. adults was about 15 percent toward the end of the study, slightly lower than in previous years.
The authors divided participants into five categories based on sugar intake, from less than 10 percent of daily calories - the safest amount - to more than 25 percent. Most adults exceed the safest level; and for 1 in 10 adults, added sugar accounts for at least 25 percent of daily calories, the researchers said. The researchers had death data on almost 12,000 adults, including 831 who died from heart disease during the 15-year follow-up. They took into account other factors known to contribute to heart problems, including smoking, inactivity and excess weight, and still found risks for sugar.
As sugar intake increased, risks climbed steeply. Adults who got at least 25 percent of their calories from added sugar were almost three times more likely to die of heart problems than those who consumed the least - less than 10 percent. For those who got more than 15 percent - or the equivalent of about two cans of sugary soda out of 2,000 calories daily - the risk was almost 20 percent higher than the safest level.
Sugar calories quickly add up: One teaspoon has about 16 calories; one 12-ounce can of non-diet soda contains has about 9 teaspoons of sugar or about 140 calories; many cinnamon rolls have about 13 teaspoons of sugar; one scoop of chocolate ice cream has about 5 teaspoons of sugar. Dr. Jonathan Purnell, a professor at Oregon Health & Science University's Knight Cardiovascular Institute, said while the research doesn't prove "sugar can cause you to die of a heart attack", it adds to a growing body of circumstantial evidence suggesting that limiting sugar intake can lead to healthier, longer lives.

Why girls sexy online profile image has more Negative consequences than Positive?

Why Sexy online profile photos not a good idea?


I think this study shows lot of truth…
If you want to know why Young women with sexy social media photos seen as less competent, you will know after reading this new study.
Girls and young women who post sexy or revealing photos on social media sites such as Facebook are viewed by their female peers as less physically and socially attractive and less competent to perform tasks, a new study from Oregon State University indicates.

Why girls sexy online profile image has more Negative consequences than Positive?

“This is a clear indictment of sexy social media photos,” said researcher Elizabeth Daniels, an assistant professor of psychology who studies the effect of media on girls’ body image. Daniels’ findings are based on an experiment she conducted using a fictitious Facebook profile.“There is so much pressure on teen girls and young women to portray themselves as sexy, but sharing those sexy photos online may have more negative consequences than positive,” Daniels said.
Girls and young women are in a “no-win” situation when it comes to their Facebook photos, Daniels said. Those who post sexy photos may risk negative reactions from their peers, but those who post more wholesome photos may lose out on social rewards, including attention from boys and men, she said. “Social media is where the youth are,” she said. “We need to understand what they’re doing online and how that affects their self-concept and their self-esteem.”

Why girls sexy online profile image has more Negative consequences than Positive?
Daniels’ research was published today in the journal Psychology of Popular Media Culture. The article, titled “The price of sexy: Viewers’ perceptions of a sexualized versus non-sexualized Facebook profile photo,” was co-authored by Eileen L. Zurbriggen of the University of California, Santa Cruz. Daniels conducted the research while on the faculty at OSU-Cascades and received two Circle of Excellence grants from OSU-Cascades to support the study. She is now an assistant professor of psychology at the University of Colorado in Colorado Springs. For the study, Daniels created two mock Facebook profiles for the fictitious 20-year-old Amanda Johnson. In both versions, Amanda liked musicians such as Lady Gaga, books such as “Twilight,” and movies like “The Notebook,” that would be appropriate for a person her age.

The only difference between the two was the profile photo. The photos were actual high school senior portrait and prom photos of a real young woman who allowed the photos to be used for the experiment. In the sexy photo, “Amanda” is wearing a low-cut red dress with a slit up one leg to mid-thigh and a visible garter belt. In the non-sexy photo, she’s wearing jeans, a short-sleeved shirt and a scarf draped around her neck, covering her chest.

Why girls sexy online profile image has more Negative consequences than Positive?
Study participants were 58 teen girls, ages 13-18, and 60 young adult women no longer in high school, ages 17-25. They were randomly assigned one of the profiles and asked questions based on that profile. The participants were asked to assess Amanda’s physical attractiveness (I think she is pretty), social attractiveness (I think she could be a friend of mine), and task competence (I have confidence in her ability to get a job done) on a scale from 1-7, with one being strongly disagree and 7 being strongly agree. In all three areas, the non-sexy profile scored higher, indicating that those who viewed that photo thought Amanda was prettier, more likely to make a good friend and more likely to complete a task. The largest difference was in the area of task competence, suggesting a young woman’s capabilities are really dinged by the sexy photo, Daniels said.
The research underscores the importance of helping children and young people understand the long-term consequences of their online posts, Daniels said. Parents, educators and other influential adults should have regular conversations about the implications of online behavior with teens and young adults, Daniels suggested. “We really need to help youth understand this is a very public forum,” she said. The research also highlights the need for more discussion about gender roles and attitudes, particularly regarding girls and young women, she said. “Why is it we focus so heavily on girls’ appearances?” she said. “What does this tell us about gender? Those conversations should be part of everyday life. “Daniels’ advice for girls and young women is to select social media photos that showcase their identity rather than her appearance, such as one from a trip or one that highlights participation in a sport or hobby. “Don’t focus so heavily on appearance,” Daniels said. “Focus on who you are as a person and what you do in the world

Scientific reasons- Why drinking coffee before exercise is great IDEA

0 comments
This is good news for the people who love coffee.
The Spanish study, published in the International Journal of Sport Nutrition and Exercise Metabolism, found that trained athletes who took in caffeine pre-exercise burned about 15% more calories for three hours post-exercise, compared to those who ingested a placebo.
How many bucks for your brew? The dose that triggered the effect was 4.5 mg of caffeine per kilogram of body weight. For 150-pound woman, that's roughly 300 mg of caffeine, the amount in about 12 ounces of brewed coffee, a quantity you may already be sipping each morning. If you've always thought of coffee as a vice -- one you're simply not willing to give up -- you'll be happy to know that it's actually a secret superfood. And if you exercise, caffeine can offer even more functional benefits for your workouts.


Scientific reasons- Why drinking coffee before exercise is great IDEA
Here are many reasons to enjoy it as part of an active lifestyle, along with some "rules" for getting your fix healthfully.

Muscle preservation
In an animal study, sports scientists at Coventry University found that caffeine helped offset the loss of muscle strength that occurs with aging. The protective effects were seen in both the diaphragm, the primary muscle used for breathing, as well as skeletal muscle. The results indicate that in moderation, caffeine may help preserve overall fitness and reduce the risk of age-related injuries.

Improved circulation
Recent Japanese research studied the effects of coffee on circulation in people who were not regular coffee drinkers. Each participant drank a 5-ounce cup of either regular or decaffeinated coffee. Afterward, scientists gauged finger blood flow, a measure of how well the body's smaller blood vessels work.
Those who downed "regular" (caffeinated) coffee experienced a 30% increase in blood flow over a 75-minute period, compared to those who drank the "unleaded" (decaf) version. Better circulation, better workout -- your muscles need oxygen!
 Scientific reasons- Why drinking coffee before exercise is great IDEA
Less pain

Scientists at the University of Illinois found that consuming the caffeine equivalent of two to three cups of coffee one hour before a 30-minute bout of high-intensity exercise reduced perceived muscle pain. The conclusion: caffeine may help you push just a little bit harder during strength-training workouts, resulting in better improvements in muscle strength and/or endurance.

Better memory

A study published this year from Johns Hopkins University found that caffeine enhances memory up to 24 hours after it's consumed. Researchers gave people who did not regularly consume caffeine either a placebo or 200 mg of caffeine five minutes after studying a series of images. The next day, both groups were asked to remember the images, and the caffeinated group scored significantly better.
This brain boost may be a real boon during workouts, especially when they entail needing to recall specific exercises or routines.

More muscle fuel
A recent study published in the Journal of Applied Physiology found that a little caffeine post-exercise may also be beneficial, particularly for endurance athletes who perform day after day.
The research found that compared to consuming carbohydrates alone, a caffeine/carb combo resulted in a 66% increase in muscle glycogen four hours after intense, glycogen-depleting exercise. Glycogen, the form of carbohydrate that gets stockpiled in muscle, serves as a vital energy "piggy bank" during exercise, to power strength moves, and fuel endurance.

Some basic rules to best reap caffeine's rewards

Don't overdo it.
The maximum amount of caffeine recommended for enhancing performance with minimal side effects is up to 6 mg per kg body weight, which is about 400 mg per day (or about 16 ounces of coffee) for a 150-pound woman.

Incorporate it in healthy ways
Doctor up coffee with almond milk and cinnamon instead of cream and sugar, or whip coffee or tea into a fruit smoothie, along with other nutrient-rich ingredients like almond butter and oats or quinoa.

Be consistent with your intake
 Research shows that when your caffeine intake is steady, your body adjusts, which counters dehydration, even though caffeine is a natural diuretic. In other words, don't reach for two cups one day and four the next.

Keep drinking good old water, your main beverage of choice
