Yogurt Fights Stomach Ulcers

In an article published in HealthDay News on Monday, March 23, a new kind of yogurt is available in some countries in the Pacific rim and it seems to combat ulcers and gastritis, reports a team of Japanese researchers.

The finding is the result of a study of 42 people who tested positive for Helicobacter pylori (H. pylori), a bacteria which causes ulcer. The participants were given two cups of yogurt a day. Some had regular yogurt. The rest had the new type which contained the antibody IgY-urease. One month later, the participants were retested.

Their tests results showed that those who consumed fortified yogurt had lower urea (a urease byproduct) levels, compared to those who ate regular yogurt. The results suggest that there is less bacterial activity, according to the researchers during their presentation last March 22 at a meeting of the American Chemical Society in Salt Lake City.

Study coordinator Hajime Hatta, a chemist at Kyoto Women’s University in Kyoto, Japan, believes that though antibiotics were more effective at controlling the ulcer-causing bacteria, people would rather have a few helpings of yogurt as part of their diet than take medications, especially since the antibody does nothing to alter the taste or cause serious side effects, says

The yogurt though, may not be for everyone. Hatta cautioned that it may cause reaction in people who have allergies to milk or eggs.

Hatta’s team created the antibody after observing that H. pylori counts on urease (a protein) to attach to and infect the stomach lining. They then injected chickens with urease, hoping that the birds’ immune systems would create an antibody that could protect the stomach lining. The resulting IgY-urease antibody was then collected from the chickens’ eggs, put in the yogurt, and then tested on people with H. pylori infection.

IgY-urease antibody, according to researchers, is eventually killed by stomach acid.

The new, IgY-urease antibody-fortified yogurt is now available in Japan, Korea and Taiwan.
