The standard medical advice - given by most GPs and health professionals such as midwives - is based on a 1998 UK Government issued precautionary notice for women with a family history of atopy (asthma, eczema or hay fever) to avoid eating peanuts during pregnancy and breast-feeding as this could increase the chances of peanut sensitization in children.
But the findings of a study by scientists Dr Tara Dean and Dr Carina Venter at the University of Portsmouth of 858 pregnant women and 660 children suggests the Government medical advice is being followed mostly by first-time mothers regardless of family history of atopy. Researchers questioned the women about their diets, and two years later, conducted skin prick tests on the children to detect peanut sensitization.
The findings revealed that 65 per cent of women (whether atopic or not) followed the advice and stopped eating peanuts. The skin prick tests revealed 13 out of 660 children were sensitized to peanuts (two per cent of the sample). Of this group of 13 children, 11 had a family history of atopy, while 10 out of 13 mothers said they avoided peanuts during pregnancy.
"Mothers of 77 per cent of children sensitized to peanuts had avoided peanuts during pregnancy. In this cohort study, maternal consumption of peanuts during pregnancy was not associated with peanut sensitization in the infant," the scientists wrote in a paper published this week in the Journal of Human Nutrition and Dietetics.
The scientists called for a review of the 1998 Department of Health advice issued by the Committee on Toxicity in Chemicals in Food, Consumer Products and the Environment (COT).
"It is likely that the COT advice is either misunderstood by mothers of that those who communicate that advice have not fully explained who it is targeted at," the scientists said.
"Not surprisingly, most mothers who heard the advice had heard of it through their midwives. At the first booking appointment (during the first trimester), midwives highlight certain dietary precautions to safeguard the baby's well-being. It is likely that avoidance of peanut is often communicated as blanket advice or interpreted as blanket advice regardless of family history of atopy. It has previously been shown that this 'blanket approach' causes confusion amongst mothers (Turke et al., 2005).
"This study reveals the requirement for clear, consistent factual advice and information about the real risks associated with peanut consumption during pregnancy/lactation and peanut allergy in the developing child, and specifically to whom these risks apply."
The research was carried out at The David Hide Asthma and Allergy Research Centre on the Isle of Wight (UK).

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
