Associations between ultra-processed foods intake and preserved ratio impaired spirometry in U.S. adults
Summary
Researchers analyzed data from U.S. adults and found that higher intake of ultra-processed foods was associated with an increased risk of impaired lung function. The association was particularly notable in individuals with occupational exposure to respiratory hazards. While the study focused on diet and lung health rather than microplastics directly, ultra-processed foods are a known source of microplastic exposure, adding another dimension to concerns about highly processed food consumption.
Higher intake of UPFs is linked to an increased risk of PRISm and negatively affects lung function, particularly in individuals with occupational exposure.

Ultra-processed food exposure and adverse health outcomes: umbrella review of epidemiological meta-analyses
This umbrella review of epidemiological studies examines the health effects of ultra-processed foods, which are a significant source of human microplastic exposure due to plastic packaging. Ultra-processed foods have been linked to a wide range of adverse health outcomes in population studies. The connection between processed food packaging and microplastic contamination adds another dimension to why reducing ultra-processed food consumption may benefit health.
Microplastics, potential threat to patients with lung diseases
This review examines the potential threat that airborne microplastics pose to people with existing lung conditions, noting that these particles have been found in human lung tissue and sputum. Researchers explored possible mechanisms by which inhaled microplastics could worsen lung diseases, including triggering inflammation and oxidative stress. The study highlights significant knowledge gaps and calls for more research into how microplastic inhalation affects respiratory health.
Microplastics and mental health: The role of ultra-processed foods
This paper proposes that microplastics in ultra-processed foods may partly explain why these foods are linked to worse mental health outcomes. With over 50% of calories in the U.S. coming from ultra-processed sources, and recent findings showing alarming microplastic levels in human brains, the authors suggest that food processing and packaging introduce microplastics that could affect brain function.
A job exposure matrix for occupational exposure to airborne micro and nanoplastics (PlastiXJEM®) and associations with respiratory outcomes
Researchers studied over 136,000 people and found that workers with high exposure to airborne microplastics and nanoplastics had reduced lung function and more breathing problems like shortness of breath and asthma. Jobs with the highest plastic particle exposure included those in manufacturing, construction, and textile work. While this study only looked at one point in time, it suggests that breathing in tiny plastic particles at work may harm lung health and warrants more research into protecting workers.
Microplastics Exposure Impact on Lung Cancer—Literature Review
This review examines the relationship between micro- and nanoplastic exposure and lung cancer development, summarizing evidence that these particles can enter the respiratory system through inhaled air, contaminated food, and other pathways. Researchers found that microplastics may promote inflammatory and oxidative processes in lung tissue that are associated with cancer progression. The study suggests that chronic microplastic exposure warrants consideration as a potential contributing factor in lung cancer research.
