A recent study, published in the journal Nature Medicine, shows that microbiota, aka gut bacteria, play a crucial role in protecting humans against food allergies.
During the study, two groups of mice without their own bacteria received gut bacteria from either healthy human babies, or from human babies with cow’s allergy milk. The first group of mice didn’t experience any allergic reaction to cow’s milk, while the other had allergic reactions to cow’s milk.
Senior study author Cathryn R. Nagler, Ph.D., a professor in food allergy at the University of Chicago in Illinois, USA, says: “This study allows us to define a causal relationship and shows that the microbiota itself can dictate whether or not you get an allergic response.”
Australian scientists report that they developed an immune-based therapy able to treat peanut allergy in kids. After this therapy, children could eat peanuts without any reactions for four years.
A team of Australian researchers added probiotics to an earlier developed immunotherapy treatment which combined probiotics with small doses of peanuts. The results of the research showed that 82% of kids receiving the therapy significantly reduced their allergic reactions to peanuts compared to 4% of children who didn’t receive any treatment.
Dr. Anna Nowak-Wegrzyn, an associate professor of pediatrics at Icahn School of Medicine at Mt. Sinai Hospital, says: “I think there is certainly a suggestion, but not hard proof, that the probiotics make a difference.”
If you suffer from a dry cough at night, or you just can not fall asleep for a long time, complaining about discomfort, irritation, and similar factors, then simply revise your own bedding, including pillows. According to experts, you can be disturbed by dust mites.
Research in this area held by a group of scientists from the United States. According to the head of the research group Dr. Lisa Okerli if pillows were not changed for about 10 years, they can have dust mites. These organisms can provoke allergic reactions, dry cough and watery eyes.
It should be noted, however, that bedding remains cells of dead skin, which feed dust mites. Researchers note that these organisms are not dangerous in themselves, and allergic reactions are caused by a substance such as an enzyme, which is produced bu those mites. It is necessary to take into account the factor that in people who have chronic respiratory problems or allergies, the situation is aggravated even more.
To prevent this, you can regularly make a wet cleaning, and laundry, change pillows. In addition, experts recommend not to fill the bed, and leave the room on the ventilation. This type of mites like heat and humidity, so these conditions are critical. It is recommended to wash bedding at 60 degrees, since such high temperatures can beat dust mites.
A new review suggests that feeding infants eggs and peanuts early can prevent allergies to these foods later in life. The review, based on 146 studies of more than 200,000 children, was published in the Journal of the American Medical Association.
According to the reviews, children who were given eggs at the age of four to six months old had a 40% lower chance to develop egg allergy than those eat this food later.
Allergy specialist Robert Boyle from Imperial College London, a co-author of the study says: “Introducing egg and peanut at an early age may prevent the development of egg and peanut allergy, the two most common childhood food allergies.”
Don’t know whom to blame in watery eyes, hives and runny nose? Specialists of the University of Southampton (UK) found a connection between allergy and season, in which you were born. Most adverse predictions got children born in autumn and winter.
Previously, scientists have repeatedly tried to link a person’s birth month to a variety of health effects. The large-scale study at Columbia University (USA) in 2015 even showed a correlation of 55 diseases with the season of birth. Now this list has replenished with allergies.
Southampton researchers conducted epigenetic measurements of DNA samples of 367 people who were born on the island Wight of the south coast of Great Britain. These epigenetic factors are responsible for the “cellular memory”, which is, although a natural function of our body, but it can have negative effects on health.
Scientists have discovered that a modification of DNA molecule that is responsible for the tendency to allergic diseases is indeed related to the time of the birth: in comparison with the spring children, those who born in autumn have increased susceptibility to eczema, atopic dermatitis and asthma.
Dr. Gabriel Lockett, a co-author of the study, said that all of this may seem like a health horoscope, but we now have scientific evidence that such a “horoscope” works. Discovered epigenetic markers may potentially be a trigger for other seasonal diseases.
In the future, scientists are going to find out how the different seasons change disease risk factors, and what role is played by temperature, sunlight and food.
