Is barbecuing unhealthy? Facts about grilling and health
BBQing has a dual reputation: on the one hand, it's seen as one of the purest ways to prepare meat, while on the other, there are questions about the health risks of grilling at high temperatures. What's true about these concerns — and how do you grill as healthily as possible?
The risks of BBQing — what does science say?
When grilling meat at high temperatures, two groups of harmful substances can form:
PAHs (polycyclic aromatic hydrocarbons)
PAHs are formed when fat and meat juices drip onto glowing coals and burn. The rising smoke then settles on the meat. PAHs are carcinogenic in high concentrations. The keywords here are high concentrations and regular exposure — occasional BBQing poses negligible risks.
HCAs (heterocyclic amines)
HCAs form within the meat itself at very high temperatures (above 200°C) and prolonged direct contact with the heat source — especially in charred meat. Again, with moderate and proper BBQing, the concentrations are low.
How do you limit the risks?
- Avoid charring — charred meat contains the highest concentrations of HCAs. Cut away any burnt pieces.
- Use indirect heat — with indirect grilling, fat doesn't drip onto the coals, greatly reducing PAH formation. → Direct vs. Indirect Heat Explained
- Marinate with herbs — research shows that marinades with rosemary, thyme, and other antioxidant-rich herbs significantly reduce HCA formation. Dry rubs with herbs have a similar effect.
- Avoid very fatty meat directly over coals — use a drip pan for fat when grilling fatty meat directly.
- Use clean, blue smoke — white smoke (incomplete combustion) contains more harmful compounds than blue smoke. → Blue vs. White Smoke Explained
Is grilling low-calorie?
Yes, relatively speaking. When grilling, fat drips away from the meat instead of being cooked into it. Compared to pan-frying or deep-frying, grilling is one of the least caloric preparation methods for meat. This makes BBQ naturally suitable for those who want to eat low-calorie — provided you're careful with fatty sauces and bread.
Healthier BBQing — practical tips
- Choose chicken, fish, and lamb more often alongside red meat
- Use a dry rub instead of a sweet, sugary sauce
- Grill more vegetables — vegetarian BBQing is healthy and flavorful
- Limit highly processed meats (sausages, low-quality hamburgers) — opt for fresh meat
- Moderate portion sizes and combine with fresh salads and vegetables as a side dish
Conclusion
Occasional BBQing is not unhealthy — especially if you avoid charring, use indirect heat, and apply herb-rich rubs. The risks are relevant with daily, structural exposure to burnt meat and white smoke — not with the average summer BBQ session.
