In the last few decades, ultra processed foods have flooded the market, often with unhealthy additives and high levels of sugar, salt and fats. Getting accurate information about the content of processed foods has been challenging until now. Researchers at Mass General Brigham have developed a database and website available to consumers to better understand the degree of processing. They gathered information of ingredients in some fifty thousand processed foods available at three leading grocery stores. The goal is to add even more processed foods to their database, but in the meantime the information may be useful to the public at www.truefood.tech. The article is published in the journal Nature Food.
