Partners Can Help or Hinder Attempts at Changing Diet

For people trying to make a change in their diet, significant others generally play a positive and supportive role, but sometimes respond in negative ways, according to a study in the March/April Journal of Nutrition Education and Behavior (

Led by Judy Paisley, Ph.D., R.D., of Ryerson University, Toronto, the researchers looked at how significant others responded when their partners attempted to make a dietary change for health reasons. "For most pairs, the significant others' emotional and behavioral responses to the dietary change appeared to reflect the general dynamics of the relationship," says Dr. Paisley.

The researchers conducted interviews with 21 people making dietary changes—most in response to a medical diagnosis—and with their partners or significant others. "By examining the perspectives of significant others, we hoped to deepen understanding of the social nature of dietary change," Dr. Paisley explains.

The partners' emotional responses varied widely: from co-operation and encouragement to skepticism and anger. In most cases, the significant others described themselves as playing a positive, supportive role. Some facilitated the change by joining in the new diet, or by changing their shopping or cooking habits. Others helped by monitoring the dietary change, finding and sharing information, or providing motivation.

These positive roles seemed to reflect the general dynamics of the relationship, according to Dr. Paisley. "Significant others who demonstrated strong support for their partner's dietary change typically described their relationship as very supportive and often saw their direct participation in the change as a natural extension of their relationship."

However, in some cases, the person trying to make a change felt their partner had a negative impact on their efforts—for example, by eating 'forbidden' foods in front of them. In these cases, the significant others did not view their response as negative. In only one case did both partners agree that the significant other played a neutral role.

Most studies of the role of social support on dietary behavior have focused on the perspective of the person attempting to make a change. The researchers hope that their study will aid in developing ways of promoting dietary modifications as a shared activity.

"Although most significant others described their response as co-operative and supportive, the responses varied widely in terms of the impact that their support may have had on changers’ experiences," adds Dr. Paisley. "For example, indirect indications of support like not complaining about dietary changes may have been less meaningful to changers than direct support offered through positive reinforcement and encouragement."

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

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...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

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...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

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...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
