Female brain responds more actively to food! Why?

Female brain responds more actively to food. North American study explains greater obesity among women.

The women’s brain responds more actively when exposed to food than men, why women are more obese than men, showed a U.S. study published in the journal “Proceedings of the National Academy of Sciences.

The study, led by researchers Gene-Jack Wang, Brookhaven National Laboratory, and Nora Volkow, director of the National Institute of Drug Addiction and co-author of the discovery published by the National Academy of Sciences, says that women have the least capacity men to suppress hunger, which may explain the fact that there is more obesity among the female gender.

The researchers performed brain monitoring of the 13 women and ten men in fasting, when they found a different signal in the brain of women when exposed to their preferred food. Even using the technique of cognitive inhibition, used to suppress the thought of food and hunger, the brain responds to food of women remained active, while the man fell.

“The difference of gender is somewhat surprising and the nutritional needs may be responsible for this,” said Nora Volkow. He added: “The fact that the traditional role of women is to provide food for their children may be a stimulus in the brain of women to consume foods when available.”

Eric Stice, expert on eating disorders, described the discovery as provocative, saying that the difference may be related to the difference in estrogen and hormones between men and women. In 2006, 35.5 percent of North American women were obese, compared with 33.3 percent of men, according to data centers of control and prevention of diseases in the United States.

Could Nanotechnology Make An Average Candy Into Health Food?

European food companies already use nanotechnology in consumer products, but few volunteer the information to consumers, said Dutch food scientist Frans Kampers.


He is among the panelists gathered in Chicago for the American Association for the Advancement of Science annual meeting symposium “From Donuts to Drugs: Nano-Biotechnology Evolution or Revolution.”

Kampers from Wageningen University and Research Center in the Netherlands will take a look at food science issues in his presentation, “What Nanotechnology Can Do for Your Average Donut.”

“All of us as scientists are being impacted by nano-bioscience and there are many issues. The interdisciplinary aspect is just one of them,” said Rod Hill, a University of Idaho professor and symposium organizer.

The panel includes two graduate students, Jessica Koehne of the University of California, Davis, and Kristina Kriegel of the University of Massachusetts, are working on projects combining, nanotechnology with biology and chemistry.

“On the food side there is greater public resistance to nanomaterials and nanotechnology in food whereas on the biomedical side there is greater public acceptance or less recalcitrance,” Hill added.

His focus on applications, products and processes, and on sensors useful for in food safety and food quality monitoring and in packaging, reflects the wide range of nanotechnology’s use in the food industry, Kampers said.

“The problem I always face is that people do not understand what we are doing with nanotechnology and food,” Kampers said. “Everyone has this vision of nanotechnology being nanoparticles and nanoparticles being risky, so they are very afraid that nanoparticles in food will have an adverse effect on health.”

The promise of nanotechnology, the Dutch scientist said, is that it could allow re-engineering ingredients to bring healthy nutrients more efficiently to the body while allowing less-desirable components to pass on through.

European food scientists use nanotechnology to create structures in foods that can deliver nutrients to specific locations in the body for the most beneficial effects, Kampers said.

“We are basically creating nanostructures in food that are designed to fall apart in your body because of digestion so in the end there will not be nanoparticles,” Kampers said.

He said there are some researchers studying applications of persistent nanoparticles in food and packaging that he believes could present risks. Use of metal, usually silver, nanoparticles in packaging to slow spoilage could move from the packaging material into the food itself.

“The persistent metal or metal oxide nanoparticles could move into the bloodstream, and research has shown they can migrate into cells or in some cases even into the nucleus of cells,” Kampers said.

“These are the more controversial applications of nanotechnology,” Kampers added. “More research is necessary to understand the kinetics and dynamics of these particles before large-scale applications in food are developed. At the moment, these types of nanoparticles are rarely used in food products.”

Divorce Notice Before the American Elections: Blue to Red States

Dear Red States:

If you manage to steal this election, too, we’ve decided we’re leaving. We intend to form our own country, and we’re taking the other Blue States with us. In case you aren’t aware, that includes California, Hawaii, Oregon, Washington, Minnesota, Wisconsin, Michigan, Illinois and all the Northeast. We believe this split will be beneficial to the nation, and especially to the people of the new country of New California.

Best of George W. Bush!

Here is the best our former american president did while he was in office:

SO LONG SUCKER!!!

Pokémon!! Gonna catch’em all?

You know the story, a little and cute bug that can be your friend and evolves to a stronger animal when it has all the requisites. Oh, I almost forget… when or if  you see one you have to take your pokéball and catch the cute being for you! this is the story, and actually it’s nothing special but this kid (above) make it superb. The Pokemón Freak, one of the best comic movies  I have already seen… hilarious, a classic!

My last point of view, actually it’s not mine (JA it’s you!), who is the expert behind the camera? He did want to make it in such a perfect way that put the fantastic slow motions in the video and makes the video even better. Congratulations cameraman! 😉
