According to researchers, ultra-processed foods are mostly made of substances extracted from foods such as oil, sugar and starch, but they have been altered so much by processing and the addition of chemicals and preservatives to enhance their appearance or shelf life. Researchers said that they are difficult to identify from their original form.
These include packaged cake mixes, for example, or packaged French fries, hamburger buns and soft drinks.
When it comes to fast food, gloves worn by employees and equipment used in storage, preparation, or serving can be the main sources of risk. Both frozen and fresh ingredients would be subject to these sources, said lead author Brennan Baker, a postdoctoral researcher in Satyanarayana’s lab.
Researchers say this is the first study to identify a link between exposure to phthalates in ultra-processed foods and socioeconomic issues faced by mothers.
