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 new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
