and the scientists involved say that may be true of other foods as well. Another study suggests that the satiating effect of calories could be more mental than chemical.
Calories are not just calories said Rick Mattes professor of foods and nutrition at Purdue University in West Lafayette Ind.
Blowing up your food A calorie is a measurement of heat a concept originating with the 19th century French scientist Nicolas Clã ment in 1824.
The term calorie when used with food usually refers to the amount of heat required to raise the temperature of a kilogram of water one Degree celsius.
American scientist Wilbur Atwater used calories as a unit to measure the energy in food in the 1890s according to David Baer of the USDA's Agricultural research service.
A small pellet of the food being measured is placed in a device that looks like a pressure cooker.
and then the food is ignited. Thermometers measure the heat given off and that is the calorie count.
because you literally explode the food and capture the heat and measure it said Susan Roberts professor at the Friedman School of Nutrition Science and Policy at Tufts University in Boston Mass.
All you are doing is measuring how much heat the food converts to when you burn it.
 Not all food is digested. What is digested not is excreted out of the body in feces and urine.
Some of the food provides the energy required to eat or drink--chewing for example. This is called metabolized energy.
Estimating the metabolized energy in food gets complicated. It involves mathematical calculations of proteins carbohydrates
By knowing what food went in and what came out the researchers were able to measure the metabolic energy of the individual nuts.
The numbers used on food packaging is the metabolizing energy using the Atwater factor. What the USDA experiment did was actually measure the unused calories as opposed to doing the calculation.
Caloric minds games Scientists have known for a while that the form of food makes a difference. People think solid food is more filling than liquids despite the calorie count.
The Purdue researchers wanted to know if that was true We think our hunger drops less
Both Baer and Mattes will present papers at the Institute for Food Technologists meeting in Chicago on July 14.
 Tufts'Roberts thinks calories still count The environment is so full of junk food and excess portions that the only way many people can keep their weight healthy is to watch what they eat she said.
And for that you need numbers because even if you have a Ph d in nutrition it is impossible to accurately tell how many calories are in most of the foods out there.

The AHA says a healthy diet includes a variety of foods and is rich in fresh fruits and vegetables.
Recently the U s. Food and Drug Administration (FDA) issued new proposed standards governing oversight over the pet-food industry calling for makers of animal food sold in the United states to develop written plans to prevent food
A company called Menu Foods headquartered in Canada then blended and packaged pet food under dozens of different labels that sickened
and revamping portions of the Food Cosmetic and Drug Act. The FDA's recent proposal amounts to a rule-making a partial follow up to the 2010 law that the Congress passed.

#Celebrity Endorsements May Spur Kids'Unhealthy Eating Kids eat more of a food product that has been endorsed by a celebrity researchers report in a new study.
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
The researchers found that those who had watched the commercial with the celebrity ate more of the chips labeled with the brand name compared with the kids who watched a commercial for a different food
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.
Wheat rye and barley are common in many foods like bread pasta baked goods and pizza.
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
Food allergy exposures can be immediately life threatening and can also be treated with an Epipen

8 Foods for Healthy Teeth Regular brushing 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.
Now a growing body of research is finding that certain foods may be good for teeth too.
Here are eight teeth-friendly foods that show promise. Tea: Â Compounds called polyphenols found in black
After eating the foods the adolescents and teens rinsed their mouths with water. The acid or ph levels in their mouths were measured then 10 20 and 30 minutes after rinsing.
Crunchy foods: It takes serious chewing to break down foods such as carrots apples and cucumbers. But all that crunching isn't in vain.
Chewing may disturb dental plaque and serve as a cleansing mechanism Wu said. Â So instead of remaining in your mouth
Vitamin-rich foods: 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.
Calcium is also good for bones including your jaw. Sugarless gum: Pop a stick in your mouth after eating.
Chewing boosts saliva secretion clearing away some bacteria Wu said. The keyword here is sugarless.
And because it may evoke thoughts of food and get digestive juices flowing some people hypothesized that chewing gum could make people hungrier.
and colleague Jennifer Temple of the University at Buffalo asked 44 volunteers to play a slotmachine-style game in exchange for food.
In a second experiment the researchers asked participants to keep a food journal recording what they ate.
and snack for a week while other times they simply had to record their food intake.
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.

In one game dogs saw their owners hide food under a cup but then point to the opposite cup.
Purebreds were statistically more likely to choose the cup their owner pointed to rather than the cup they remembered seeing the food go into.
In a slightly different version of the game dogs saw their owner hide the food
but then the owner switched the food to the other cup while the dog's eyes were covered.
but mixed breeds were significantly more likely than purebreds to use their memory to locate the food.
With obesity in pets on the rise it is important for pet owners to factor in not only their dog's food

#Food Allergy, or Food Intolerance? The Healthy Geezer answers questions about health and aging in his weekly column.
Meanwhile you might want to keep a diary of all the foods you eat. Doing this will isolate those foods that are triggering digestive problems.
The intensity of your reaction can determine whether or not you are allergic to certain foods
or have a food intolerance. A food allergy is an abnormal response to a food that's triggered by the body s immune system.
This type of reaction occurs quickly ometimes within minutes. Reactions include itching in the mouth vomiting diarrhea and abdominal pain.
You may experience a drop in blood pressure asthma and skin reactions such as hives or eczema. An allergic reaction to food can cause serious illness and in some cases death.
Sometimes a reaction to food is not an allergy but a food intolerance. Food intolerance is more common than food allergy.
The immune system doesn't cause the symptoms associated with a food intolerance though they can be similar to those of a food allergy.
Many people think they have food allergies. However most symptoms are caused by intolerances to foods such as wheat and other grains the sugar in fruits and honey dairy products and corn products.
If fruit juices are giving you a stomachache there is a possibility that you have a fructose intolerance.
Fructose is a sugar that's found in fruits honey and some syrups. It's also a basic component in table sugar (sucrose)
and it's used to sweeten many processed foods and beverages. In addition sorbitol a sugar alcohol is converted to fructose during digestion.
Sorbitol is a sugar substitute often used in diet drinks ice cream mints cough syrups and sugar-free chewing gum.
You should avoid foods containing fructose. In addition to fruits honey syrups and table sugar watch out for high-fructose corn syrup powdered sugars regular sodas flavored waters sports drinks and sweetened milks.
Read food labels carefully to avoid fructose. The term fructose intolerance covers two conditions: hereditary fructose intolerance and fructose malabsorption.
People with hereditary fructose intolerance a rare genetic disorder lack an enzyme that breaks down fructose.

but contamination of water and food (such as raw produce) with oocyst-containing fecal matter likely contributes to the dissemination.
Risks of infection increases via the common factors consumption of untreated food or water lack of adequate sanitation and the presence of animals in the house.
because their diet especially acacia leaves their favorite food contains a lot of water. When they do get thirsty they have to bend down awkwardly to drink
Their height helps them reach food well above where other animals can reach. A giraffe may eat more than 75 pounds (34 kilograms) of food each day.
Because they get just a few leaves in every bite they spend most of their day eating Acacia trees have long thorns that deter most animals but not giraffes.
so it can get by on less food. Hippos usually gather in groups of about 15 called bloats pods

Common in processed foods in both GMO and non-GMO formulations soybean oil has high levels of omega-6 fatty acids
Genetically modified organisms in this discussion genetically modified foods have genetic material that engineers unnaturally altered.

The U s. government's stance GMOS are allowed not in any food certified as organic by the U s. Department of agriculture (USDA.
However in an online food Q&a the U s. Food and Drug Administration (FDA) stated that GMOS have been in the U s. food supply for about 20 years.
The agency also stated in a consumer update that Foods from genetically engineered plants must meet the same requirements including safety requirements as foods from traditionally bred plants.
Such foods the FDA added are generally as nutritious as foods from comparable traditionally bred plants...
or toxic reaction than foods from traditionally bred plants. Additionally Michael Jacobson executive director of the Center for Science in the Public interest said there is no safety hazard in using genetically modified soybean oil over conventional soybean oil a finding the organization highlighted recently in its Nutrition Action newsletter.
However the federal government does not require that GMO foods be labeled as such. Food manufacturers may indicate through voluntary labeling
whether foods have or have not been developed through genetic engineering provided that such labeling is truthful and not misleading the agency stated.
No studies have found GM foods to be harmful but many concerned citizens and scientists believe there have not been sufficient longitudinal (making observations over a substantial period of time) nor clinical studies on the effects of GMOS on human health.
Environmental consequences of GM foods As for the environment GMOS seem to have impact. Recently a rogue strain of Monsanto GM wheat was found in a field in Oregon.
and corn two crops largely dedicated to processed foods? We should instead fill our fields with an array of fruits and vegetables!
and attempted to eat those five cups a day there wouldn't be enough of the food to go around!
Soybean oil is a great example of a genetically modified food often associated with misinformation. Because of its low cost soybean oil is used in a vast quantity of the processed foods Americans eat.
Just look at the food-label ingredient lists in your own kitchen cabinet. This is a problem
because soybean oil provides a substantial amount of omega-6 fatty acids. Omega-6 fatty acids although essential to the human body are required in very minute amounts
