Emulsifiers help to preserve the texture of many ultra-processed foods. Prior research has linked the consumption of emulsifiers to an increased risk of gut inflammation, obesity, and other health conditions.
In addition, unbalanced nutritional habits by pregnant or nursing mothers has been linked to long-term health risks in offspring. However, the specific effects of maternal consumption of emulsifiers on offspring have been unclear.
Assessing Emulsifiers Effects In Mice
Mil-Guasch and colleagues provided laboratory mice with water containing two kinds of emulsifiers commonly found combined together in human foodcarboxymethylcellulose and polysorbate-80.

From before pregnancy until the nursing offspring, female mice received the maximum concentration of each emulsifier allowed in human food products by the Food and Agriculture Organization and the World Health Organization. For comparison, other mice received water without any emulsifiers.
The researchers found that the offspring of mice that consumed emulsifiers had a greater risk of certain health issues, including mild metabolic, cognitive, and psychological injuries. These effects were strongest in male offspring, but female offspring also showed impairments.
A combination of gene-expression testing and other lab tests suggested that maternal consumption of emulsifiers led to perturbation of the development of neural circuits in the offspring’s hypothalamusa part of the brain that plays a central role in regulating metabolism.
Additional research will be needed to further clarify the effects on offspring of emulsifier consumption by pregnant and nursing people. Still, on the basis of their new findings, the researchers call for increased awareness of the potential risks of consumption of ultra-processed foods by mothers.
They express particular concern about products perceived to be healthy, including certain vegetarian and vegan products, which nonetheless contain emulsifiers that could potentially lead to health risks for offspring.
