Household dust could contribute to weight gain, a new study finds

Household dust could contribute to weight gain, a new study finds”

In addition, now researchers have also identified common environmental pollutants that could play a role.

Known as endocrine-disrupting chemicals (ECCs), these compounds can be synthetic or naturally-occurring, and are able to replicate, mimic and generally interfere with the body's hormones and reproductive, neurological and immune functionality. Animal studies indicate exposure to certain EDCs early in life can spur weight gain in later years.

United States researchers may have found more evidence that house dust exposure can boost fat storage.

Some product manufacturers have decreased the amount of EDCs in their offerings. Concerned about the potential effects EDCs in dust might have on children's health, researchers wanted to see if the compounds in house dust might have an effect on fat cells. It is possible EDCs affect fat cells and increase the chances for obesity.

In order to conduct the research, scientists tested samples of dust from 11 different homes in North California. They tested extracts from these samples with a mouse pre-adipocyte cell model commonly used to test compounds for effects on the buildup of triglycerides (fat).

The extracts from seven of those samples developed into mature fat cells and accumulated triglycerides, while nine samples spurred the cells to divide, creating a larger pool of precursor fat cells.

The researchers found that even a little bit of dust - an amount well below what people are exposed to daily - caused measurable effects.

A team of researchers at Duke University has claimed to have discovered a notable link between house dust particles and fat cells in human body. Among the 44 most common household dust contaminants tested in the model, the pesticide pyraclostrobin, the plasticizer DBP, and the flame retardant TBPDP generated the most robust fat-producing effects.

Researchers concluded the study by suggesting that exposure to the chemicals through house dust may disrupt metabolic health, particularly in children.
