Why is red meat a cancer risk?
Nitrates and nitrites
When we eat them, nitrites can become cancer-causing chemicals (N-nitroso compounds or NOCs). These chemicals may be the reason why processed meat increases the risk of cancer more than fresh red meat.
How carcinogenic is red meat?
In 2015, based on data from 800 studies, IARC classified processed meat as a human carcinogen (Group 1), meaning that there is enough evidence to conclude that it can cause cancer in humans. The evidence for red meat was less definitive, so IARC classified it as a probable carcinogen (Group 2A).
What meat is carcinogenic?
Consumption of processed meat was classified as carcinogenic and red meat as probably carcinogenic after the IARC Working Group – comprised of 22 scientists from ten countries – evaluated over 800 studies.
How much does red meat increase cancer risk?
Dose-response analysis showed that the intake of 120 g/d of red meat increases cancer risk by 24% and 30 g/day of processed meat increases this risk by 36% according to this meta-analysis. If average red meat intake is reduced to 70 g/week, CRC risk hypothetically decreases by 7-24%.
Is chicken a carcinogen?
Carcinogens occur naturally in chicken. In a Physicians Committee study compiled from independent laboratory tests, 100% of 100 grilled chicken samples from top restaurant chains in California contained PhIP, a federally recognized carcinogen that has been linked to breast, prostate, and other cancers.
Are eggs carcinogenic?
Eggs can be a source of carcinogenic chemicals that are formed during high temperature frying. That would be consistent with the bladder cancer data, suggesting fried egg consumption may double cancer risk, but not boiled eggs.
Is Coca Cola a carcinogen?
There have also been claims that chemicals in soft drinks can increase cancer risk. While some studies have detected very low levels of chemicals such as benzene and 4-methylimidazole (4-Mel) in certain soft drinks, there is no evidence they increase the risk of cancer at the low levels found in soft drinks.
Is canned tuna carcinogenic?
However, tinned sardines and tuna do offer a variety of health benefits, including omega 3 fatty acids. Canned food is unlikely to be a cause of cancer when consumed as part of a balanced diet.
Are apples carcinogenic?
Broccoli, apples, onions, oranges, strawberries, lemons and mushrooms all contain acetaldehyde, a natural by-product of oxidation and a known human carcinogen.
Is peanut butter a carcinogen?
Currently, all commercially produced peanut butter is tested for aflatoxin, but the less processed the peanut butter is, the more likely it contains the carcinogen.
What foods are high in carcinogens?
Of these, red and processed meats raise the most concern in terms of cancer risk. Red meat includes pork, beef, veal, and lamb. Processed meat includes bacon, ham, lunch meats, meat jerky, hot dogs, salami, and other cured meat products.

Is egg a carcinogen?
From these results it appears that both egg white and egg yolk are carcinogenic, but that their carcinogenicity differs. A carcinogenic substance causing the development of lymphosarcomas and lung adenocarcinomas, would be present in both, while a mammary carcinogen, lipid in nature, is present in the yolk only.
What foods prevent all cancers?
Foods such as broccoli, berries, and garlic showed some of the strongest links to cancer prevention. They’re low in calories and fat and power-packed with phytochemicals and antioxidants that may help reduce your cancer risk.
