Tasty Ideas to Reduce Cancer Risk

Tasty Ideas to Reduce Cancer Risk

Heterocyclic amines (HCAs) are potent cancer-causing agents. They form when meat is cooked at high temperatures. HCAs also form with frying, broiling and smoking, but not baking. High intake of grilled meat is linked with cancers of the colon, breast, prostate and pancreas.

HCAs build up on all flesh foods—meat, poultry and fish (not fruit or vegetables)—four minutes after the temperature reaches 325°F.  The longer the cooking time and the higher the temperature, the more HCAs are formed.

Polycyclic aromatic hydrocarbons (PAHs) are formed after the fat on the meat melts from the high temperature, drips onto the coals and then reattaches itself to the meat through the smoke.There are ways to reduce your exposure to these carcinogens:

  • Reduce the frequency and serving size of grilled meat
  • Choose leaner cuts, this results in less dripping fat causing flare-ups
  • Flip the meat frequently
  • Reduce the heat—cooking at slightly lower temperatures is enough to substantially reduce formation of HCAs
  • Cut off the charred portions and don’t eat them
  • Use a marinade—studies have shown that marinating your meat before grilling can decrease formation of HCAs by up to 96 percent

Using a marinade like the tip above suggests can have some exciting culinary results. The marinade should include beneficial plant ingredients. Spice rubs are popular now and these are great—you can rub these onto solid meat or add these to your recipes when you work with ground meat such as making burgers. Here are some examples:

  • Herbs and spices especially rosemary leaves or extract
  • Beer*
  • Extra virgin olive oil
  • Green or black tea
  • Garlic
  • Lemon juice

If you’re not sure where to start, begin with rosemary. Rosemary has a good track record in research studies. According to Bon Appetite Magazine, here is the basic formula for making a marinade:

Oil+Acid+Something Salty+Spices

Here are some combinations that work well together:

  • Olive oil, lemon juice, garlic, basil, oregano and thyme
  • Orange juice, lime juice, cilantro, salt and ginger
  • White wine, Dijon mustard and cayenne pepper

*In a study on the effectiveness of 3 different types of beer on the reduction of PAHs on grilled pork, black beer was the most effective followed by non-alcoholic pilsner and pilsner (see reference list below for more details)
