THURSDAY, March 8 (HealthDay News) — Eating too much lunch meat,
bacon, hot dogs and such could worsen symptoms of airway diseases like
emphysema and chronic bronchitis, a new study suggests.
These diseases, which cause inflammation of the lungs that make it
difficult for a person to breathe, are commonly included under the
umbrella term “chronic obstructive pulmonary disease” (COPD). Lung
infections, air pollution or tobacco smoke are common triggers for
flare-ups of the diseases and can lead to hospitalization among patients.
In the new study, researchers in Spain reported that the nitrates used
as preservatives in cured meats produce reactive nitrogen species that
could damage lung tissue, and excessive consumption of these food items
might raise the risk of hospitalization among COPD patients.
During the investigation, 274 COPD patients were monitored for an
average of two years starting with their first hospital admission for the
disease. Among other information, the participants reported on their
consumption of cured meats, such as ham, salami, pork sausage and bacon.
The study, published in the March 8 issue of the European
Respiratory Journal, found that eating large amounts of cured meats —
more than one slice of ham per day, as example — may aggravate symptoms
of COPD, causing people with the condition to be readmitted to the
hospital.
“Our findings provide the first evidence that an excessive intake of
cured meat can worsen progression of COPD. We believe that adherence to
current dietary guidelines, which recommend a moderate or occasional
intake of cured meats, will be sufficient in order to avoid this excess of
risk,” study lead author Dr. Judith Garcia-Aymerich, of the Center for
Research Environmental Epidemiology in Barcelona, said in a news release
from the European Lung Foundation.
Other than limiting nitrate-laden foods, “other individual actions such
as quitting smoking or practicing physical activity on a regular basis”
may help prevent flare-ups of the disease, she added.
The study authors noted that their research was limited by a lack of
information on changes in the patients’ diets after their first
hospitalization.
In addition, while the study found an association between greater
consumption of cured meats and flare-ups in patients with the lung
disorder, it did not prove a cause-and-effect relationship.
