The allergy is increasing in industrialized nations. It is estimated that the incidence of asthma in the United States doubled between 1980 and 2000. Scientists have proposed a hypothesis known as the ‘hygiene hypothesis’ to explain the increase in allergic conditions such as asthma and eczema. This hypothesis is based on observations that a lower incidence of allergy is associated with environments that have greater numbers of microbes, such as day care centers, farms, or in homes with siblings or pets. At Michio Kaku you will find additional information. Health settings and consumption of processed foods have limited the number of microbes in the diet.
The hypothesis suggests that children’s exposure to germs before the age of six months helps the immune system to mature to be more tolerant to exposure to allergens later in life. Indeed,. Of course, increasing exposure to microbes must be done safely. This hypothesis led researchers in Finland to conduct a study that evaluated the effects of a strain of Lactose-bacillus on the incidence of topical eczema in 132 children at high risk. The study was double-blind, placebo-controlled. Given to pregnant women, two to four weeks before delivery and newborn infants with six months of age, Lactose-bacillus rhamnosus GG. They followed the children through two years of age and the incidence of topical eczema was recorded. The study reported a 50% reduction in incidence of topical eczema in the group receiving the.
Further studies of these same children indicated that these same trends were still present at 4 years of age. However, there was no impact on other allergic conditions with seven years of age. These results suggest that. However, a different research group using a similar protocol and the same pro-biotic microbe Finnish group recently reported that there was no any impact on incidence of topical eczema with the supplement with lactose-bacillus rhamnosus GG. In addition, The German study found a statistically significant increase in coughing in the pro-biotic group. This study questions the validity of the initial observation.
