Acrolein

Irritant substance resulting from the degradation of glycerol (found in fats) when oils or animal fats are overheated. Also present in cigarette smoke or wood smoke. It is toxic for the respiratory tract and suspected to be carcinogenic.

✅ Health tip: avoid overheating oils or fats until they smoke, favor moderate cooking, and ensure good ventilation.

Acrylamide

Compound formed during high-temperature cooking (especially in starchy foods). Potentially carcinogenic.

✅ Health tip: avoid over-grilling potatoes, bread, etc.

AGEs (Advanced Glycation End Products)

Compounds formed when sugars react with proteins or fats during high-temperature cooking (especially grilling, roasting, frying). Accumulate in the body and contribute to aging, inflammation, diabetes, and cancer risk.

✅ Health tip: cook at lower temperatures, use moist cooking (marinades, steaming, indirect heat), and combine with antioxidant-rich foods.

Antioxidant Marinade

Marinade rich in herbs, garlic, onion, lemon, spices… Helps limit the formation of toxic compounds during cooking.

✅ Health tip: marinate meat for at least 1 hour with natural, antioxidant-rich ingredients.

Natural Antioxidants

Molecules that neutralize free radicals. Found in herbs, vegetables, fruits, virgin oils.

✅ Health tip: add fresh herbs and lemon to your marinades or sides.

Bark (BBQ Crust)

Crust formed during slow cooking with spice rubs. It’s flavorful and healthy if the temperature stays moderate.

✅ Health tip: avoid direct flames and charring, prefer indirect cooking.

Benzo(a)pyrene

One of the most toxic PAHs, often used as a pollution indicator in grilled or smoked foods.

✅ Health tip: avoid black deposits or burnt crusts on meat.

Brining (Salt Brine)

Technique of soaking meat in salted water (sometimes with sugar, herbs, spices). Improves moisture retention and tenderness.

✅ Health tip: prefer low-salt brines, add antioxidant herbs and citrus, and avoid industrial “enhanced” meats.

Charcoal vs. Activated Charcoal

Charcoal is used for cooking. Activated charcoal is used for filtering. When used improperly, cooking charcoal can produce PAHs.

✅ Health tip: use high-quality, dry charcoal without additives.

Chronic Inflammation

Repeated exposure to certain compounds (HCAs, PAHs, nitrosamines) can promote low-grade chronic inflammation, linked to various cancers.

✅ Health tip: balance your diet, prioritize fiber, vegetables, and antioxidants.

Collagen Breakdown

Collagen is the connective tissue protein in meat. At low temperatures (90–120°C / 200–250°F), it slowly melts into gelatin, making meat tender. At very high heat, it burns and can create harmful compounds.

✅ Health tip: favor slow cooking (low & slow BBQ) to tenderize without charring.

Dry Brining

Seasoning meat with salt (and sometimes spices) ahead of cooking, letting it rest to improve flavor and tenderness.

✅ Health tip: use moderate amounts of salt and pair with fresh herbs to boost nutrition.

HCAs (Heterocyclic Aromatic Amines)

HCAs are produced when protein-rich meats are cooked at high temperatures, especially on grills or griddles. They appear mostly above 150–200°C (300–390°F).

Several HCAs are suspected of promoting cancers, especially colorectal, with repeated exposure.

✅ Health tip: avoid very intense cooking, prefer low and indirect heat.

Hot Smoking / Cold Smoking

Hot smoking: cooking + smoke (≥70°C / 160°F). Cold smoking: smoke without cooking (<30°C / 85°F).

✅ Health tip: choose untreated hardwood, avoid greasy smoke, and monitor temperature carefully.

Indirect Cooking

Technique where the heat source is offset from the food. Allows gentler, healthier cooking.

✅ Health tip: ideal to prevent flare-ups and better control temperature.

Maillard Reaction

Reaction between proteins and sugars that gives grilled food its flavor and golden crust. At excessively high temperatures, it can generate undesirable compounds (HCAs).

✅ Health tip: aim for golden browning, not black charring.

Nitrates / Nitrites

Additives used to preserve cured meats. Nitrites can form nitrosamines when heated.

✅ Health tip: limit processed meats, prefer homemade or nitrite-free products.

Nitrosamines

Substances that can form from nitrites (in cured meats) when heated. Many nitrosamines are recognized carcinogens.

✅ Health tip: limit industrial cured meats, choose nitrite-free options whenever possible.

Omega-3 vs. Omega-6 Balance

Omega-3 fatty acids (fish, flaxseed, walnuts) are anti-inflammatory. Omega-6 (vegetable oils, grain-fed meats) can promote inflammation if consumed in excess. Modern diets are often too high in omega-6.

✅ Health tip: balance your BBQ meals with omega-3 sources (grilled salmon, mackerel, sardines, or add flaxseed/walnut oil in sides).

PAHs (Polycyclic Aromatic Hydrocarbons)

PAHs are chemical compounds formed when wood, charcoal, or animal fat burns at high temperatures. In barbecue, they often appear when fat drips onto the coals and produces black smoke.

Some PAHs are classified as probable carcinogens. They can settle on meat or be inhaled.

✅ Health tip: use a drip pan, control flare-ups, and keep the fire well ventilated.

Plant-Based BBQ

Vegetables, legumes, and plant proteins (tofu, tempeh, seitan, veggie burgers) adapt very well to grilling and avoid the risks linked to meat.

✅ Health tip: include at least one plant-based dish per BBQ session for balance and diversity.

Polyphenols

Natural compounds in wine, beer, tea, herbs, fruits, and vegetables. Act as antioxidants and can reduce PAH/HCA formation during grilling.

✅ Health tip: marinate meat in red wine or beer (boiled first to remove alcohol), with herbs and spices.

Portion Control

Even with healthier BBQ, large portions of red meat increase cancer and heart disease risk.

✅ Health tip: balance the plate with vegetables, legumes, and whole grains. Limit red meat to ~500 g (1 lb) per week, as recommended by cancer prevention guidelines.

Resting Meat

Letting cooked meat rest allows juices to redistribute, improving tenderness and flavor.

✅ Health tip: wrap in foil or cover lightly, let it rest 5–15 min depending on size, to avoid overcooking and dryness.

Salt & Sodium

Essential mineral, but excess sodium intake is linked to hypertension and cardiovascular risk. Many BBQ rubs and sauces are very salty.

✅ Health tip: reduce added salt, use spices/herbs for flavor, and make homemade sauces to control sodium.

Smoke Point of Oils

Temperature at which an oil breaks down and produces toxic compounds.

✅ Health tip: for BBQ, prefer oils with a high smoke point such as avocado oil or grapeseed oil.

Smoke Quality

Clean blue smoke (thin, almost invisible) carries flavor without excess toxins. Thick white or black smoke contains higher PAHs.

✅ Health tip: always burn clean wood, keep vents open, avoid smoldering or greasy smoke.

Sugar in BBQ

Sugar is common in rubs, glazes, and sauces. When exposed to high heat, it caramelizes (flavor) but also burns easily, leading to acrylamide and other harmful byproducts.

✅ Health tip: apply sugary sauces at the end of cooking, not at the beginning, to avoid burning.

Wood Choice

Hardwoods (oak, hickory, apple, cherry) are safe for BBQ. Softwoods (pine, spruce) contain resins that produce toxic smoke.

✅ Health tip: always use untreated hardwood, never painted or chemically treated wood.
