Healthy Grilling Tips: How to Reduce HCAs and PAHs While Boosting Flavor and Nutrition
Summer grilling season is one of life's great pleasures. The smoky aromas, the great outdoors, time with family and friends…gathering around the grill is just part of what makes summer…well, summer! But did you know that, for better health, how you grill matters just as much as what you grill? (Keep reading to the end for my special marinade…)
When meats are cooked at very high temperatures, compounds called heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs) can form. That’s a mouthful. You just need to know that these problematic for our health. Research suggests that frequent exposure to large amounts of these compounds increases health risks over time. The good news? A few simple grilling strategies can dramatically reduce their formation while making your meals even more delicious and nutritious.
What Are HCAs and PAHs?
Heterocyclic amines (HCAs) form when proteins, sugars, and creatine in meat react at high temperatures, especially during grilling, pan-frying, and broiling.
Polycyclic aromatic hydrocarbons (PAHs) are created when fat and juices drip onto hot coals or flames, producing smoke that deposits these compounds back onto food.
Keep in mind that occasional exposure isn't a cause for alarm, adopting healthier grilling habits can help reduce your overall intake.
Healthy Grilling Tips: 5 Evidence-Based Ways to Reduce Harmful Compounds…Marinades are Your Friend!
Marinades do more than add flavor…they may significantly reduce HCA formation. Research from the National Cancer Institute suggests that herb- and spice-based marinades may significantly reduce the formation of heterocyclic amines (HCAs) during grilling…by up to 70-88%. Consider ingredients such as olive oil, lemon juice, garlic, rosemary, thyme, ginger, turmeric, etc. Aim to marinate proteins for at least 30 minutes before grilling.
How to Prevent Grill Flare-Ups and Reduce PAHs
When fat drips onto flames, PAH-rich smoke rises and coats the food. Less smoke means fewer harmful compounds. To minimize flare-ups:
Trim excess fat from meat
Choose leaner cuts
Keep a spray bottle of water nearby
Move food away from direct flames when flare-ups occur
Why Frequent Flipping Can Make Grilled Meat Healthier
Contrary to popular grilling myths, turning meat frequently may actually be beneficial. Frequent flipping:
Reduces surface overheating
Lowers HCA formation
Promotes more even cooking
Pre-Cook Meat for Healthier Summer Grilling and Avoid Charring
Large cuts of meat require longer grilling times, which can increase exposure to high heat. Try microwaving chicken, ribs, or thicker cuts briefly beforehand or oven-roasting your proteins partway before finishing on the grill. This reduces total grilling time while still delivering that signature grilled flavor. Charring…I know it can add a little flavor, BUT those blackened bits contain the highest concentrations of HCAs and PAHs.
The Healthiest Meats to Grill This Summer
Not all proteins behave the same on the grill. Consider choosing:
Skinless chicken breast
Turkey
Seafood
Pork tenderloin
93% lean ground beef
Leaner proteins produce less dripping fat and generally create fewer flare-ups. Minimize processed meats such as hot dogs (sorry), sausage, bacon (even more sorry) as these have been classified by several expert health organizations as Group 1 carcinogens, meaning there is strong evidence linking frequent consumption to increased cancer risk.
Plant-Based Grilling Recipes and Seafood: Smart Alternatives for Healthy Outdoor Cooking
Fish, shellfish, tofu, tempeh, and vegetables produce little to no HCAs compared to traditional meats. Great options include: Salmon, shrimp, tuna, tofu, tempeh, portobello mushrooms.
Grilled Vegetables and Fruit: The Secret to a Healthy Cookout
Vegetables and fruits produce virtually no HCAs and provide fiber, antioxidants, vitamins, minerals, and phytochemicals that support overall health. Try grilling:
Bell peppers
Zucchini
Asparagus
Mushrooms
Onions
Corn
Pineapple
Peaches
Safe Grilling Temperatures: Food Safety Tips for Outdoor Cooking
Safe grilling is healthy grilling so always use a meat thermometer!
Cook poultry to 165°F
Cook ground meats to 160°F
Cook whole cuts of beef, pork, and lamb to 145°F followed by a 3-minute rest
Use separate plates and utensils for raw and cooked foods
Refrigerate leftovers within 2 hours (1 hour if temperatures exceed 90°F)
MZ Marinade: Green Tea and Ginger Marinade (it’s a fav of mine)
Best for: Chicken breast, chicken thighs or pork tenderloin
Ingredients
1 cup strong brewed green tea, cooled
3 Tbsp low-sodium soy sauce or tamari
2 Tbsp rice vinegar
1 Tbsp grated ginger
2 garlic cloves, minced
1 Tbsp honey
1 tsp toasted sesame oil
Directions: Combine ingredients and marinate for 1–6 hours.
