Love BBQ? Your Health Might Not Share the Sentiment

Rheumatoid arthritis (RA) is a lasting autoimmune disorder where the body’s defense mechanism mistakenly targets the joints, leading to progressive harm. This damage isn’t limited to joints but also extends to the surrounding cartilage and bones.

Primarily, the hands, wrists, and feet are the major areas affected, manifesting symptoms like pain, swelling, and rigidity.

The root cause of RA remains a mystery. Nonetheless, current scientific insights suggest a blend of genetic elements, age, gender, and environmental factors like smoking habits, dietary choices, and overall lifestyle play pivotal roles.

Researchers from the University of Maryland delved into the potential triggers for RA and made a striking discovery. They suggest that common activities, like barbecuing, might elevate the risk of RA. The study, published in BMJ Open, highlights that barbecuing exposes individuals to environmental pollutants called polycyclic aromatic hydrocarbons (PAHs). These pollutants are byproducts of burning substances like coal, oil, and even wood. Grilled foods, especially meats, and even cigarette smoke are significant sources of PAHs.

Upon exposure, these chemicals find their way into our system. The study’s recent findings link them to an amplified risk of RA. The research assessed data from the US National Health and Nutrition Examination Survey spanning 2007-2016. Out of the 22,000 adults surveyed, 1,418 had RA. The team also explored the presence of other toxins, such as chemicals used in plastic production and volatile organic compounds from paint and pesticides.

Blood and urine samples were analyzed to quantify these toxins. The findings revealed that individuals with the highest concentration of PAHs in their system were 80% more likely to have RA, regardless of their smoking habits. Other toxins weren’t directly related to increased RA risks.

The study considered various potential influencing factors like diet, physical activity, and even socio-economic status.

Dr. Christopher D’Adamo, leading the research, noted, “While PAH levels tend to be higher in adults who smoke…other sources of PAH exposure include indoor environments, motor vehicle exhaust, natural gas, smoke from wood or coal burning fires, fumes from asphalt roads, and consuming grilled or charred foods.

“This is pertinent as households of lower socioeconomic status generally experience poorer indoor air quality and may reside in urban areas next to major roadways or in high traffic areas.”

The researchers stress that these environmental toxins, omnipresent due to their diverse sources, pose significant health risks, particularly for urban inhabitants or those living in regions with subpar air quality.

It’s essential to note that this study, being observational, doesn’t definitively pinpoint the cause. There were constraints, like the unavailability of toxicant measurements in fatty tissues or the levels of heavy metals, another significant component found in cigarettes.

In conclusion, while the connection between PAHs and RA needs more extensive research, reducing exposure to such environmental toxins is deemed crucial for public health. The study findings can be accessed in the BMJ Open journal.
