Why in News?
Recently, the American Institute for Cancer Research found that grilling meat over high heat or an open flame produces cancer-causing carcinogens.
Recent Issue
- Grilled meat - Contains carcinogenic compounds that cause changes in the DNA.
- Cancer - It causes inflammation that makes you prone to cancer.
- Carcinogens found - Polycyclic aromatic hydrocarbons (PAHs) and heterocyclic aromatic amines (HCAs)
- Carcinogen group – Group 1.
Heterocyclic aromatic amines (HCAs)
- Formation - Formed when amino acids (the building blocks of proteins), sugars, and creatine or creatinine (substances found in muscle) react at high temperatures.
- Effects - Potent mutagens and carcinogens linked to an increased risk of various cancers.
Polycyclic Aromatic Hydrocarbons (PAHs)
- Formation -They are formed when fat and juices from meat grilled directly over a heated surface or open fire drip onto the surface or fire, causing flames and smoke.
- The smoke contains PAHs that then adhere to the surface of the meat.
- Other sources - Forest fires and volcanic eruptions.
- Effects - Carcinogens, mutagens, teratogens, and infertility.
Classification of carcinogens
Reducing steps
- While grilling - Always marinate, meat Shorten grill time, Flip the meat often.
- Food preferences - Never binge eat barbecue, always choose leaner meats.
