The pregnant pause for eating peanuts: Contrary to medical advice, it's okay for many women to eat peanuts when pregnant

22.03.2007
New scientific research has found that most women who follow general medical precautionary advice and avoid peanuts when pregnant may be doing so unnecessarily as the advice does not apply to them.

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).

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
