Organic labels bias consumers perceptions through the 'health halo effect'

Organic cookies are still cookies!

2013-04-01

(Press-News.org) The word "organic" can mean many things to consumers. Even so, the power of an organic label can be very strong: studies have shown that this simple label can lead us to think that a food is healthier, through what is known as the 'health halo effect'. But can this bias go further? A study by Cornell University's Food and Brand Lab researchers Lee, Shimizu, Kniffin and Wansink set out to answer this question. Their study shows that an organic label can influence much more than health views: perceptions of taste, calories and value can be significantly altered when a food is labeled "organic". Certain people also appear to be more susceptible to this 'health halo' effect than others…are you?

115 people were recruited from a local shopping mall in Ithaca, New York to participate in this study. Participants were asked to evaluate 3 pairs of products— 2 yogurts, 2 cookies and 2 potato chip portions. One item from each food pair was labeled "organic", while the other was labeled "regular". The trick to this study was: all of the product pairs were organic and identical! Participants were asked to rate the taste and caloric content of each item, and how much they would be willing to pay for the items. A questionnaire also inquired about their environmental and shopping habits.

What is organic food?

Even though these foods were all the same, the "organic" label greatly influenced people's perceptions. The cookies and yogurt were estimated to have significantly fewer calories when labeled "organic" and people were willing to pay up to 23.4% more for them. The nutritional aspects of these foods were also greatly biased by the health halo effect. The "organic" cookies and yogurt were said to taste 'lower in fat' than the "regular" variety, and the "organic" cookies and chips were thought to be more nutritious! The label even tricked people's taste buds: when perceived as "organic", chips seemed more appetizing and yogurt was judged to be more flavorful. "Regular" cookies were reported to taste better--possibly because people often believe healthy foods are not tasty. All of these foods were exactly the same, but a simple organic label made all the difference!

Who is less susceptible? This study found that people who regularly read nutrition labels, those who regularly buy organic food, and those who exhibit pro-environmental behaviors (such as recycling or hiking) are less susceptible to the organic 'health halo' effect. So, if you do not consider yourself in one these groups, take a closer look when shopping for organic foods—they are, after all, still cookies and chips!

Feeding corn germ to pigs does not affect growth performance

2013-04-01

URBANA - Inclusion of corn germ in swine diets can reduce diet costs, depending on the local cost of corn germ and other ingredients. Recent research conducted at the University of Illinois indicates that corn germ can be included at up to 30 percent in diets fed to growing pigs. "In previous research, we had seen that pigs do very well on diets containing 10 percent corn germ, so we wanted to investigate if higher inclusion rates can be used," said Hans Stein, professor of animal sciences at Illinois. The corn germ used in this study came from the ethanol, or dry grind, ...

Watching fluid flow at nanometer scales

2013-04-01

CAMBRIDGE, MA -- Imagine if you could drink a glass of water just by inserting a solid wire into it and sucking on it as though it were a soda straw. It turns out that if you were tiny enough, that method would work just fine — and wouldn't even require the suction to start. New research carried out at MIT and elsewhere has demonstrated for the first time that when inserted into a pool of liquid, nanowires — wires that are only hundreds of nanometers (billionths of a meter) across — naturally draw the liquid upward in a thin film that coats the surface of the wire. The ...

Prostate cancer risk rises in men with inherited genetic condition

2013-04-01

ANN ARBOR, Mich. — Men with an inherited genetic condition called Lynch syndrome face a higher lifetime risk of developing prostate cancer and appear to develop the disease at an earlier age, according to a new study led by researchers at the University of Michigan Comprehensive Cancer Center. Lynch syndrome is an inherited condition linked to a higher risk of several types of cancer. People with Lynch syndrome have up to 80 percent lifetime risk of colorectal cancer and are also more likely to develop endometrial, gastric, ovarian, urinary tract, pancreatic and brain ...

Mechanism of mutant histone protein in childhood brain cancer revealed

2013-04-01

Most cancer treatments are blunt. In an attempt to eradicate tumors, oncologists often turn to radiation or chemotherapy, which can damage healthy tissue along with the cancerous growths. New research from C. David Allis' laboratory at Rockefeller University may bring scientists closer to designing cancer therapeutics that can target tumors with pinpoint accuracy. Their findings, published last week in Science Express, follow a recent series of discoveries by several international genome sequencing consortiums that directly links a mutated histone protein to a rare brain ...

Electroencephalography underused investigative tool in hospitals

2013-04-01

Rochester, MN, April 1, 2013 – A retrospective study of patients who had in-hospital electroencephalography (EEG) has established that EEG is a valuable tool that could be deployed more widely to identify treatable causes of impaired consciousness in the hospital setting. The study is published in the April issue of the Mayo Clinic Proceedings. Altered mental status (AMS) and paroxysmal spells of uncertain origin are common among hospitalized patients. Impaired consciousness can sometimes be linked to metabolic or cardiac causes, but some of these spells may represent ...

Mayo Clinic: New multiple myeloma treatment guidelines personalize therapy for patients

2013-04-01

ROCHESTER, Minn. -- Researchers at Mayo Clinic Cancer Center have developed new guidelines to treat recently diagnosed multiple myeloma patients who are not participating in clinical trials. The guidelines give physicians practical, easy to follow recommendations for providing initial therapy, stem cell transplant and maintenance therapy. The guidelines are published in the current issue of the journal Mayo Clinic Proceedings and represent a consensus opinion of hematologists at Mayo Clinic Cancer Center sites in Minnesota, Florida and Arizona. "Multiple myeloma is an ...

Research deciphers HIV attack plan

2013-04-01

LOS ALAMOS, N. M., March 29, 2013—A new study by Los Alamos National Laboratory and University of Pennsylvania scientists defines previously unknown properties of transmitted HIV-1, the virus that causes AIDS. The viruses that successfully pass from a chronically infected person to a new individual are both remarkably resistant to a powerful initial human immune-response mechanism, and they are blanketed in a greater amount of envelope protein that helps them access and enter host cells. These findings will help inform vaccine design and interpretation of vaccine trials, ...

Newly approved blood thinner may increase susceptibility to some viral infections

2013-04-01

CHAPEL HILL, N.C. – A study led by researchers at the University of North Carolina indicates that a newly approved blood thinner that blocks a key component of the human blood clotting system may increase the risk and severity of certain viral infections, including flu and myocarditis, a viral infection of the heart and a significant cause of sudden death in children and young adults. For the past 50 years, people with the heartbeat irregularity, atrial fibrillation, and others at increased risk for forming potentially life-threatening blood clots have been given the ...

Congestion in the Earth's mantle

2013-04-01

Jena (Germany) The Earth is dynamic. What we perceive as solid ground beneath our feet, is in reality constantly changing. In the space of a year Africa and America are drifting apart at the back of the Middle Atlantic for some centimeters while the floor of the Pacific Ocean is subducted underneath the South American Continent. "In 100 million years' time Africa will be pulled apart and North Australia will be at the equator," says Prof. Dr. Falko Langenhorst from the Friedrich Schiller University Jena (Germany). Plate tectonics is leading to a permanent renewal of the ...

Researchers discover new clues about how amyotrophic lateral sclerosis develops

2013-04-01

Johns Hopkins scientists say they have evidence from animal studies that a type of central nervous system cell other than motor neurons plays a fundamental role in the development of amyotrophic lateral sclerosis (ALS), a fatal degenerative disease. The discovery holds promise, they say, for identifying new targets for interrupting the disease's progress. In a study described online in Nature Neuroscience, the researchers found that, in mice bred with a gene mutation that causes human ALS, dramatic changes occurred in oligodendrocytes — cells that create insulation for ...
