Researchers from Harvard University reveal that children who drink sugary fruit juice or whose mothers drank sugary beverages during pregnancy are at 79% greater risk of developing asthma.
A team of scientists has analyzed the data regarding eating habits from 1,000 mother-child pairs. They also examined information on kids’ health, including whether they had been diagnosed with asthma between 7 and 9 years.
Study co-author Sheryl Rifas-Shima says: “In addition to influencing asthma through increasing the risk of obesity, we found that sugary beverages and high fructose may influence the risk of asthma not entirely through obesity. This finding suggests that there are additional mechanisms by which sugary beverages and fructose influence asthma risks beyond their effects on obesity.”
A team of researchers from the University of Technology Sydney, Australia, discovered that a flavoring with bitter compounds found in tonic water can prevent asthma, as well as limit characteristics of mice that already have the condition.
Scientists found that chloroquine and quinine, substances that stimulate bitter taste buds, successfully prevent and mitigate asthma in mice models and human cell culture.
Pawan Sharma, one of the researchers of the study, explains: “We do not have an effective anti-asthma therapy that targets disease progression. Our current research on taste receptors is crucial in identifying new classes of drugs that can be an effective asthma treatment option in future.”
A new research that will be presented on Saturday at the American Academy of Allergy, Asthma & Immunology annual meeting suggests that children born to moms with low levels of vitamin E might be at higher risk of developing asthma later.
For the study, a team of scientists tracked health of more than 650 kids and their mothers within the children’s first year of life. They found that kids who wheezed or needed asthma treatment were more likely to have mothers who had lower levels of vitamin E right after birth.
Lead author Dr. Cosby Stone Vanderbilt University Medical Center in Nashville said that his team’s previous research in mice had suggested the link between vitamin E and asthma.
A new Danish study found that women who took fish oil supplement during the last trimester of pregnancy significantly cut the risk of asthma in their kids.
In the study, among children whose mothers took capsules with fish oil, 16.9% had asthma by age 3 and among children whose mothers were given placebo 23.7% developed asthma to that age. This difference shows that a risk reduction is about 31%.
Dr. Hans Bisgaard, the leading author of the study, says: “It was not possible to tell from the study whether pregnant women could benefit from simply eating more fish. Pregnant women are generally advised to limit their consumption of certain types of fish like swordfish and tuna because they contain mercury. But many other types are considered safe, especially smaller fish like sardines that are not at the top of the food chain and therefore not likely to accumulate mercury and other contaminants from eating other fish.”

The study of nearly 1,000 French people, published in the journal Thorax, suggests that eating processed meats such as sausages, salami and ham that contain a preservative called nitrite can worsen asthma symptoms. However, the researchers say that more investigations are needed.
In the study, people from France took part in a survey about food and health within the period from 2003 to 2013. Nearly half of them were asthma patients.
The survey concentrated on asthma symptoms such as breathlessness, wheeze, chest tightness, and intake of processed meats.
People who reported consuming more than 4 portions of processed meat (for example, 8 sliced of ham or 4 sausages) had the biggest worsening of their asthma by the end of the study.
