If celebrity endorsement of foods high in fat and sugar continues and their appearances in other contexts leads to unhealthy eating then this would mean that the more prominent the celebrity the more detrimental the effects on children's diets the researchers wrote in their study
which will be published in a future issue of the Journal of Pediatrics. Researchers at the University of Liverpool in England looked at 181 children between ages 8 and 11.
or gluten-sensitive enteropathy cannot eat gluten. Gluten is a protein found in foods processed from wheat and other grains.
Exposure to gluten damages the lining of the small intestine interfering with the absorption of nutrients from food and often causing abdominal pain.
The word celiac sometimes spelled coeliac or cåiac is derived from the Greek koiliakã s abdomen.
When a person with celiac disease consumes gluten the immune system overreacts and targets the body s small intestine.
Patients with celiac disease who do not follow a gluten-free diet often suffer from malnutrition.
It s important that the patient continue to consume gluten before the blood tests to properly measure the immune system s response to that diet.
a lifelong gluten-free diet. This diet must be strict as even the smallest amount of gluten can trigger damage to the small intestines and reverse the healing process.
Full healing in children usually takes six months while full healing can take much longer for adults.
However the gluten-free diet will ease many symptoms significantly once implemented. Â Removing gluten from your diet completely is a difficult transition.
Wheat rye and barley are common in many foods like bread pasta baked goods and pizza.
But even small amounts can cause a reaction and this can be found in products like candies chocolates and many snack foods.
It s also important for those with celiac disease to avoid cross-contamination in their own kitchens or at restaurants.
and have only one fryer everything cooked in that fryer will be contaminated with the batter. So even French fries which do not normally contain wheat as an ingredient would not be cooked safe
Many gluten-free alternatives are available like gluten-free bread gluten-free pasta and gluten-free baked goods.
The gluten-free food industry is booming and is expected to exceed more than $5 billion by 2015.
They are made with potato rice soy or bean flour. Relief for many celiac disease sufferers can happen almost immediately after starting the strictly gluten-free diet.
Celiac disease should not be confused with a gluten sensitivity intolerance or allergy. Though gluten sensitivity often has the same symptoms as celiac disease it does not cause the same damage
and risks that celiac disease does. Food allergies occur when a body s immune system overreacts to a food and produces Ige antibodies as a reaction producing histamines
and causing skin breathing and heart problems. This process is very different from what happens when a celiac sufferer consumes gluten.
Though they both are overreactions of the immune system food allergies are characterized often by anaphylactic reactions
whereas gluten exposures for celiac sufferers cannot. Living with celiac disease can be daunting and cause anxiety.
#Champagne Toasts: How Climate Affects the Quality of Bubbly As partiers around the world cheer to the New Year this evening many will enjoy a crisp burst of fizz to the nose before gulping down a tart glass of bubbly.
while still small and tart and containing less sugar than standard non-sparkling wine grapes. The moment the grapes reach their perfect balance of tartness
which as with drought and excess heat limits sugar production and can produce a tart fruit.
because the dead trees turned a bright ginger color. The trees were bulldozed eventually and buried in trenches.
and flossing help keep teeth healthy by getting rid of sugars and food particles that team up with bacteria to form plaque.
Plaque produces acid that damages tooth enamel causes cavities and sets the stage for periodontal or gum disease.
and green teas slow the growth of bacteria associated with cavities and gum disease. Researchers at the University of Illinois at Chicago found that people who rinsed their mouths with black tea for one minute 10 times a day had less plaque buildup on their teeth than people who rinsed their mouths with water.
Research published in the journal General Dentistry earlier this year reported that 12-to 15-year-olds who ate cheddar cheese had lower acid levels in their mouths than thoseâ who ate sugar-free yogurt
but the cheese eaters had a rapid drop at each measurement interval. Â Cheese may neutralize the plaque acid said Wu who was involved not in the cheese study.
What's more chewing increases saliva production. Like a river saliva washes out some of the bacteria in the mouth she said.
Naturally sweet raisins don't contain sucrose or table sugar. Sugar helps bacteria stick to the tooth surface letting them produce plaque Wu said.
Some compounds in raisins also affect the growth of bacteria associated with gum disease Wu has found.
Foods containing calcium such as cheese almonds and leafy greens and foods high in phosphorous such as meat eggs and fish can help keep tooth enamel strong and healthy according to the American Dental Association.
Acidic foods and beverages may cause tiny lesions on tooth enamel Wu said. Calcium and phosphate help redeposit minerals back into those lesions.
Sugarless gum: Pop a stick in your mouth after eating. Chewing boosts saliva secretion clearing away some bacteria Wu said.
and her team found that drinking a glass of milk after downing dry sugar-sweetened Fruit Loops lowered levels of acid in the mouth more than drinking water
Drinking a glass of milk after eating a sweet dessert like chocolate cake may protect teeth too.
If milk isn't handy nibble on some post-dessert cheese. Cranberries: Cranberries contain polyphenols
Because the fruit is so tart many cranberry products have added sugar which may affect any potential benefits for teeth Wu said.
#Chewing gum Doesn't Lead to Weight Loss, Study Suggests Contrary to popular diet advice chewing gum may not help people eat less
or lose weight new research suggests. In fact the study published in the April issue of the journal Eating Behaviors suggests that chewing gum may lead people to eat chips cookies and candy instead of fruits and veggies.
That's because menthol the chemical responsible for the minty-fresh flavor of some types of gum makes fruits
and veggies taste funny. The chemical change is the same reason why when you brush your teeth
Chewing gum can aid test performanceâ and xylitol-sweetened gum may reduce ear infections in children.
And because it may evoke thoughts of food and get digestive juices flowing some people hypothesized that chewing gum could make people hungrier.
But scientists have hypothesized also the opposite that the act of chewing could make people feel more full
To test that claim the gum manufacturer Wrigley even offers grants for scientific research on the subject.
The 7 Biggest Diet Myths Debunked But despite claims to the contrary only a few studies have looked at
whether chewing gum aids weight loss and these have found conflicting results Swoboda said. We were interested in seeing'Does this really help with weight loss?'
and colleague Jennifer Temple of the University at Buffalo asked 44 volunteers to play a slotmachine-style game in exchange for food.
Prior to playing the game half of the participants chewed either Juicy Fruit gum or Wrigley's Spearmint gum.
Those who chewed the minty gum were significantly less likely to play as long for the fruit suggesting they were motivated less to get them when chewing gum.
The fruity gum showed a smaller effect that wasn't statistically significant. In a second experiment the researchers asked participants to keep a food journal recording
Some of the time the participants were asked to chew a mint green-tea gum before every meal
When chewing gum participants ate fewer meals. But that didn't translate into fewer calories: Instead people were actually getting fewer nutrients in their diet and about the same amount of calories.
It could be that the menthol in mint which interacts with nutrients in fruits and veggies to create a bitter flavor was turning people off to the healthy foods Swoboda said.
People ate less fruits and vegetables because in their head they thought'I have to chew gum before every meal do
I really want a snack of grapefruit?''she said. Whereas they were like 'I'm so hungry
I'm going to eat this double cheeseburger and it will taste the same.''Long-term effect?
The findings are interesting but they don't reveal how gum might change people's eating habits in the long run said Brett Carter a food behavior researcher at the University of Washington in Seattle who was involved not in the study.
In addition using food diaries is a notoriously inaccurate measure of calories Carter added. As you can imagine people aren't very good at keeping track of exactly how they eat Carter told Livescience.

and only leaving after they're full (they typically get full before the meat runs out).
To make up for the relatively brief amount of time spent with kills in the grassland the big cats must kill more prey to get the same amount of meat said Elbroch who works for Panthera a conservation group dedicated to preserving big cats.
A lot of meat Female cougars weigh about 85 pounds (39 kilograms) while males average about 150 pounds (68 kg) Elbroch said.

Eating avocados regularly may improve the quality of your diet and some key heath markers according to a new analysis. After crunching the data from the National Health
and Nutrition Examination Survey (NHANES) from 2001 to 2008 researchers found that eating avocados was associated with an overall better-quality diet;
which indicates how closely diets follow the Dietary Guidelines for Americans. The study reported that people who ate avocados had significantly higher intakes of fruits and vegetables in general and lower intakes of added sugars.
The avocado eaters also had higher intakes of total fat monounsaturated fat polyunsaturated fat dietary fiber Vitamin e magnesium potassium and Vitamin k along with a lower intake of carbohydrates.
These findings suggest a role for avocados in improving dietary quality and possibly reducing the risk of metabolic syndrome in the United states the researchers wrote.

Biologist Allan Savory explained in a talk at the TED 2013 conference in Long beach Calif. last month that he was taught to hold livestock accountable for incurring such damage on the land
And in Africa where he was working to set up national parks in the 1950s Savory thought elephants were also to blame for the land's deterioration.
I will carry that to my grave Savory told the audience. One good thing did come out of it:
Turning course Savory now believes that the only option left to combat desertification is to use livestock bunched
while the periodic trampling ensured good cover of the soil Savory said. Savory has worked with communities to implement a holistic style of grazing that attempts to mimic this process.
It involves keeping cattle in dense herds and moving them frequently so that the land is overused not

because everyone supposed they only ate meat. Although early research suggested crocodilians were unable to digest sugars
and other plant-based nutrients subsequent work with the American alligator has demonstrated otherwise. Crocodilians do not chew any fruit would likely get swallowed whole to digest in the strong acids of their guts.
Crocodilians always surprise us Platt said. I've been doing research on them for 25 years and

The breakthrough in today s paper is the sequencing of the entire genome of a Ctenophore known as the sea walnut (Mnemiopsis leidyi.
They have eight rows of comb plates with cilia that provide them with locomotion. They are carnivorous hermaphroditic marine creatures that do not sting.
The sea walnut (M. leidyi) is native to the western Atlantic but has been introduced to the Black Caspian
The sea walnut genome contained 16548 protein coding genes 44%of which shared homology-a type of ancestry-with non-Ctenophores.
As sea walnuts glow when disturbed so does this study shed light on some interesting assumptions about animal evolution.
The findings were similar for consumption of peanuts as well as tree nuts including walnuts hazelnuts and almonds.

Complications The primary complication of diarrhea is caused dehydration by the loss of large amounts of water salt and nutrients.
While water is fine it does not replace lost salt or nutrients so better choices are broth tea with honey sports drinks
and pulp-free juices. Avoid milk products caffeine alcohol and apple and pear juices since they may worsen diarrhea.
Soft bland foods are recommended as well including bananas plain rice toast crackers boiled potatoes smooth peanut butter cottage cheese noodles and applesauce.
Because yogurt cheese and miso contain probiotics which contain strains of bacteria similar to those in a healthy intestine they are also good choices.
Mcdonald's Burger king and others now offer salad fruit and skim milk. The new offerings advertised prominently would make one think that a trip to the local burger joint is suddenly heart-healthy and waistline-friendly.
Based on the Healthy Eating Index a measure of diet quality that assesses conformance to federal diet guidelines the overall health quality of fast food was poor the researchers found.
Supersize those fries and diet Coke So yes you now can get a side salad.
But along with adding some greens the restaurants also have added less healthful items in terms of calories fat salt sugar
Mcdonald's has improved the nutritional profile of its Happy Meals by adding apple slices and reducing the portion size of french fries;
So what's a health-conscious consumer to do for lunch aside from packing it? A salad at just about any fast-food chain might not be the answer.
Analyses by the Physicians Committee for Responsible Medicine (PCRM) has found that most fast-food salads are not any more healthful than a greasy burger.
You need to be creative when eating at fast-food restaurants said Ulka Agarwal chief medical officer for the Washington D c.-based PCRM a health-advocacy group that also conducts its own research.
Agarwal said to watch for unhealthy items in disguise such as salads with bacon and fatty dressings pre-added.

And this list runs the gamut with the usual suspects primates chewing on medicinal herbs as well as some more surprising drug-takers such as fruit flies ants
Fruit flies for example will lay their eggs in more alcoholic fruit (produced by natural fermentation) when parasitic wasps are hanging around said Todd Schlenke an Emory researcher who wasn't involved in the review paper.
When parasitic wasps are scarce the flies prefer to lay their eggs in less fermented fruit.

what could be the earliest evidence of ancient human ancestors hunting and scavenging meat. Animal bones and thousands of stone tools used by ancient hominins suggest that early human ancestors were butchering and scavenging animals at least 2 million years ago.
The findings published April 25 in the journal PLOS ONE support the idea that ancient meat eating might have fueled big changes in Homo species at that time.
and hominins leaving Africa for Eurasia said study co-author Joseph Ferraro an archaeologist at Baylor University in Waco Texas. The meaty meals may have provided the energy for those transformations he said.
Previously the earliest evidence of eating meat found in Olduvai gorge in Tanzania dates to 1. 8 million years ago.
and scavenging for meat until more than a million years later Ferraro said. Ancient hunters Exactly what caused big changes in human ancestors about 1. 9 million years ago has been a mystery.
Some studies suggest a shift toward a meat-heavy diet enabled the changes while others suggest that it wasn't only the meat
but cooking meat that made us human. More than a decade ago researchers unearthed a trove of thousands of stone tools piled atop animal bones in sandy silty sediment off the shores of Lake victoria in Kenya.
The artifacts at the site known as Kanjera were about 2 million years old and provided some of the earliest evidence of human species living in grassland rather than forest.
and to remove their meat and their organs Ferraro told Livescience. The combination of evidence suggests the animals must have been hunted not scavenged.
