The findings also reinforce the researchers’ earlier findings that a fish-rich diet in pregnancy can help to protect children from asthma and allergies.
“We believe that this is the first study that has assessed the impact of a child’s diet on asthma and allergies and also taken into account the food their mother ate during pregnancy” says lead author Dr Leda Chatzi from the Department of Social Medicine at the University of Crete, Greece.
“Because we studied the children from pregnancy to childhood, we were able to include a wide range of elements in our analysis, including maternal diet during pregnancy, breastfeeding, smoking, the mother’s health history, parental education and social class.”
Researchers followed the progress of the children, on the Spanish island of Menorca, at regular intervals from before they were born until they were six-and-a-half.
They discovered that children who consumed more than 40 grams of “fruity vegetables” a day – namely tomatoes, eggplants (aubergines), cucumber, green beans and zucchini (courgettes) - were much less likely to suffer from childhood asthma.
And children who consumed more than 60 grams of fish a day also suffered less childhood allergies, echoing the protective effects they experienced when their mothers ate fish during pregnancy.
However the researchers noted that the dietary effects were quite specific and that other fruits and vegetables examined did not provide the same protective effect. Nor did other food groups included in the study, such as dairy products, meat, poultry and bread.
The mothers of 232 boys and 228 girls, who had been recruited during antenatal classes, completed detailed questionnaires on their children’s health, weight, diet and any breathing problems every year until their child was six-and-a-half.
90 per cent of the children also underwent allergy testing – skin prick tests were used to check their response to the six most common allergens, including grass pollen and cats.
The researchers found that just under nine per cent of the children suffered from some degree of wheezing, including six per cent with an allergy-related wheeze. And 17 per cent reacted to at least one of the allergens in the skin prick test.
“After adjusting the results for a wide range of variables, we concluded that the link between symptom-free children and a diet rich in fruity vegetables and fish was statistically significant” says Dr Chatzi.
“The biological mechanisms that underlie the protective affect of these foods is not fully understood, but we believe that the fruity vegetables and fish reduce the inflammation associated with asthma and allergies.
“The interesting thing about this study is that it followed a large number of children from the womb to the age of six-and-a-half and incorporated a wide range of dietary, social and health factors” says the Journal’s Editor, Professor John Warner, Head of the Department of Paediatrics at Imperial College London.
“It provides parents with specific advice about the health promotion benefits of including fish and fruity vegetables as part of a balanced diet for both their children and the rest of the family.”

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
