The study of nearly 1,000 French people, published in the journal Thorax, suggests that eating processed meats such as sausages, salami and ham that contain a preservative called nitrite can worsen asthma symptoms. However, the researchers say that more investigations are needed.
In the study, people from France took part in a survey about food and health within the period from 2003 to 2013. Nearly half of them were asthma patients.
The survey concentrated on asthma symptoms such as breathlessness, wheeze, chest tightness, and intake of processed meats.
People who reported consuming more than 4 portions of processed meat (for example, 8 sliced of ham or 4 sausages) had the biggest worsening of their asthma by the end of the study.

A new study, published in the journal Cancer Research, claims that emulsifiers that are added to many processed foods can cause colon cancer in mice. They are chemicals that are used to keep food products stable and safe on shelves.
Emelie Viennois from the Institute of Biomedical Sciences at Georgia State University, a lead author of the research, showed in her earlier work that these chemicals changed good bacteria in the guts of mice. In this study, the researcher found that animals who consumed emulsifiers had changes in their gut microbiomes that were associated with promoting tumor growth.
Emelie Viennois advises: “I would tell people to try to cook instead of using food industry products. In meals, mix processed foods with some homemade food so you don’t have huge exposure to emulsifiers in one meal.”
