Mom's sweet tooth may be linked to child's allergies, study says

The researchers looked at allergies of which produce respiratory as well as skin symptoms, including dust mites, cats as well as grass. “Allergic asthma” causes breathing problems, like wheezing as well as coughing, from the presence of common allergens such as dust.

Researchers via Queen Mary University of London used data gathered via nearly 9,000 mother-child pairs from the Avon Longitudinal Study of Parents as well as Children, an ongoing research project of which tracks the health of families with children born between April 1, 1991, as well as December 31, 1992.

According to the earth Health Organization, 235 million people have asthma, as well as the item’s a common disease among children. of which number can be anticipated to raise to 400 million by 2025. The American Academy of Allergy, Asthma & Immunology reports of which worldwide, sensitivity to one or more allergens among children can be approaching 40% or 50%, as well as 10.6% of children reported respiratory allergies from the previous 12 months in 2012.

“The dramatic ‘epidemic’ of asthma as well as allergies from the West from the last 50 years can be still largely unexplained — one potential culprit can be a change in diet,” said Annabelle Bedard, lead author as well as a postdoctoral fellow at Queen Mary’s Centre for Primary Care as well as Public Health Blizard Institute. “Intake of free sugar as well as high fructose corn syrup has increased substantially over This particular period.”

“Free sugars” include those of which are naturally present in honey, syrups as well as unsweetened fruit juices — though not those in whole vegetables as well as fruits — as well as those of which are added to food as well as beverages by the any, the cook or the consumer.

“We know of which the prenatal period may be crucial for determining risk of asthma as well as allergies in childhood as well as recent trials have confirmed of which maternal diet in pregnancy can be important,” Bedard wrote in an email.

To investigate a potential connection between a mom’s diet as well as a child’s allergies, Bedard as well as her colleagues calculated the amount of free sugars consumed by the women during pregnancy based on self-reported estimates in questionnaires.

Next, the team looked at how the moms’ sugar consumption compared with allergies as well as asthma diagnosed from the children beginning age 7.

Nearly 62% of the children did not have any allergic conditions, nevertheless the remaining children had one or more maladies or symptoms. About 22% of the kids had a common allergy, 16% had eczema, 12% had asthma, 11% had wheezing with whistling, as well as 9% had hay fever, the researchers found.

Then, the researchers compared the children of moms who ate the least sugar during pregnancy — less than 34 grams, or 7 teaspoons, per day — with the children of moms who ate the most — between 82 as well as 345 grams, or 16 as well as 69 teaspoons, per day.

Are prenatal vitamins worth the money?

The children of women with highest sugar intake during pregnancy had a 38% higher risk of allergy diagnosis, the researchers calculated. Kids of the moms in This particular group had a 73% increased risk of being diagnosed with an allergy to two or more allergens. as well as the allergic asthma risk increased by 101% for children of moms from the high-sugar consumption group, meaning the risk of developing allergic asthma was double of which of kids born to women from the low-sugar group.

Only weak evidence linked sugar consumption during pregnancy to chronic asthma, the researchers say. as well as there were no ties between a mother eating sweets during pregnancy as well as either eczema or hay fever.

Bedard as well as Seif Shaheen, senior researcher of the study as well as a professor at Queen Mary, emphasized of which the research can be simply observational as well as so does not conclude of which moms who eat sugar during pregnancy cause allergies in their children.

“Similarly, we cannot rule out the possibility of which the main findings arose by chance,” Bedard said.

With such strong results, though, the team can be continuing to examine the issue as well as trying to replicate the findings among two various other groups of children, Bedard explained.

Sheena Cruickshank, senior lecturer in immunology at the University of Manchester as well as a representative for the British Society for Immunology, said the item can be unclear via the study findings how strong the effect can be.

“More studies will be needed to work out if there can be any causation in This particular relationship,” said Cruickshank, who was not involved from the fresh research. “Atopic diseases, such as allergy as well as asthma, are complex as well as associated with many genetic as well as environmental effects, including the microbes as well as pollutants we are exposed to.”

Bacteria are commonly found within the digestive tracts of all humans. When the item comes to babies, Cruickshank noted of which the item can be well-known of which This particular bacterial content “can be influenced by how a baby can be delivered, the type of milk the baby can be fed as well as their diet as they grow older.”

“Future studies should look to take these variables into account so we can understand the full relationship between maternal diet during pregnancy as well as allergic disease from the offspring,” Cruickshank said.

Dr. Shannon M. Clark, a spokeswoman for the American College of Obstetricians as well as Gynecologists as well as an associate professor at University of Texas Medical Branch-Galveston, said the large number of participants was a strength of the study. However, the researchers did not examine each mother’s sugar intake until after 32 weeks of pregnancy.

“As a result, the impact of exposure early in pregnancy cannot be assessed,” said Clark, who was not involved from the research. “As with any study of This particular design, additional research would certainly be ideal.”

Nutrition guidelines via the earth Health Organization as well as the US Department of Agriculture recommend everyone limit sugar in their diets.

Clark noted of which pregnant women need to eat healthy diets to reduce risk of developing gestational diabetes, a form of diabetes of which occurs in pregnancy as well as of which can be more common among overweight as well as obese mothers.

“Eating excessive amounts of sugar in pregnancy can put the mother at risk for developing gestational diabetes,” she said. “Gestational diabetes increases the risk of having a large baby, cesarean delivery as well as preeclampsia.” as well as babies born to women with gestational diabetes may have problems with breathing, low glucose levels as well as jaundice.

For pregnant women, Bedard said, the item would certainly be “prudent” to follow general nutritional guidelines cautioning against eating an abundance of sugary products — “whether or not we subsequently show of which a high sugar intake in pregnancy causes allergy from the offspring.”
