Fish during pregnancy may protect baby from asthma

New York, Oct 3: Women who consume fish during pregnancy are just as likley to protect their offspring from developing asthma as those who consume fish oil supplements, suggests a new study.

Pregnant women who consume high doses of omega-3 fatty acids in the third trimester may help protect their kids from developing breathing problems in their early childhood, according to the study.

“With almost equal to slightly higher cost, consuming 8-12 ounces (2-3 servings) of fish with low mercury levels a week not only may attain the same asthma protection, but also strengthen the nutritional benefits to infant growth and development,” said Richard Lockey, Professor at the University of South Florida in the US.

The study, published in the Journal of Allergy and Clinical Immunology: In Practice, was conducted in three groups of women in their third trimester.

The first group consumed omega-3 fatty acids from fish oil daily while the second group took a placebo. The third group was named the “no oil” group who were allowed to consume either fish or fish oil supplements as per their choices.

The researchers found that the children in the fish oil and the “no oil” groups took less asthma medication as they aged to 24 years old, inferring both groups developed less asthma.

“Omega-3 fatty acids cannot be synthesised by humans and therefore are essential nutrients which are derived exclusively from marine sources,” said iChen Hsing Lin from the University of South Florida.(IANS)

Here’s How Flavoured E-Cigarettes Can Worsen Asthama

Certain flavoured E-Cigarettes, even without nicotine, may change how airways, affected by an allergic disease, function, thus worsening the severity of diseases such as asthma, say researchers.

For the first time, a model of asthma was used to investigate the effect of a range of popular e-cigarette flavours, with and without nicotine.

“This is especially important for those with respiratory disease, whom are vulnerable to the effects of smoking,” Dr Chapman said.

“The majority of e-cigarette smokers use flavoured liquids but there is some evidence that flavour additives can be toxic when inhaled,” said Dr David Chapman from from the University of Technology Sydney (UTS).

The use of e-cigarettes has dramatically increased in the past few years, especially among younger smokers globally.

Despite the suggestion they are a healthier alternative to tobacco cigarettes, there is a lack of evidence in both animal studies and human data on the effect of e-cigarettes on lung function.

The researchers found that some flavoured e-cigarettes, even in the absence of nicotine, can worsen disease severity.

“The exact effects on features of asthma were dependent upon the specific flavour, suggesting not all flavoured e-cigarettes will have the same consequences on lung health,” Dr Chapman said in the study published in Scientific Reports.

In this study, the flavour Black Licorice exaggerated airway inflammation whereas Cinnacide had the opposite effect, suppressing airway inflammation.

The researchers didn’t analyse the liquids directly, to confirm what they contained, however there is evidence from previous research that flavours categorised as “buttery/creamy” and “cinnamon”, which likely include “Banana Pudding” and “Cinnacide”, respectively, are toxic.
