Willett was among dozens of speakers on the opening day of the Institute of Food Technologists Annual Meeting & Food Expo here, the world’s largest annual food science forum and exposition.
While some trans fats occur naturally in foods, most are the result of cooking or baking with hydrogenated oils. Those oils provide creamy textures that are enjoyable to eat and affect positively the shelf life and stability of many foods like baked goods
“Human life is more important that shelf life,” Willett said. “Food scientists are capable of creating products that are free of trans fats and still have shelf life.”
Denmark has banned trans fats and other European countries have reduced their use. But researcher Ronald Mensink of Maastricht University in The Netherlands, said a more moderate approach is good.
“You make no friends with the word, ‘Ban,’” he said.
Still, Mensink argues that Europeans agree that dietary trans fats should be consumed in as low amounts as possible, or less than 1 percent of the diet.
While Willett holds up New York City as the trend leader among other cities enacting trans fat bans, he concurred that “a careful, thoughtful proactive national legislation is the best approach.”
Since January 2006, food labels have listed the amount of trans fats per serving, though there is no recommended daily allowance.
A significant problem in replacing these hydrogenated oils with healthier ones lies in the supply of soybean, canola, rapeseed and alternative crops to make replacement oils. A According to Brent Flickinger, research manager of Archer Daniels Midland Co., farmers are not yet producing enough of these to replace more abundant varieties.
Now in its 67th year, the IFT Annual Meeting + Food Expo is the world’s largest annual scientific forum and exposition on food. Ranked among the largest U.S. conventions, the meeting delivers comprehensive, cutting-edge research and opinion from food science-, technology-, marketing- and business-leaders; online at http://IFT.org/amfe. Meetings run through Wednesday.
Founded in 1939, and with world headquarters in Chicago, IFT is a not-for-profit international scientific society with 22,000 members working in food science, technology and related professions in industry, academia and government. As the society for food science and technology, IFT brings sound science to the public discussion of food issues. For more on IFT, see http://IFT.org.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
