The nitrogen-based chemicals can be transformed into toxic chemical‚ n-Nitrosamines‚ under acidic environment or high temperature while cooking. Scanlan RA states that the most common Nitrosamines occur in

However‚ antioxidants like vitamin C and E may inhibit nitrosamine formation. Studies have linked it to various types of cancer. * It has been linked to the triggering migraines in migraine prone individuals. * Frequent ingestion of cured meats may

More recently‚ medical research has shown that sodium nitrate and nitrite have been linked to numerous modern-day illnesses‚ including heart disease and pancreatic cancer. The preservative is converted in your body to nitrosamines‚ which are toxic to humans and promote the growth of cancer cells. Sodium nitrite is not good for your health at all. Potassium bromate (KBrO3)‚ is a bromate of potassium and takes the form of white crystals or powder. It is also an ionic compound

specifically to babies. Therefore‚ it is illegal to use nitrites on fresh meat but it can still be used on packaged meats. Another health concern is the discovery of nitrates in contaminated water. Once the nitrate enters our body it can create nitrosamines which can cause cancer and it has also been shown to cause birth defects. Additionally‚ the nitrate can react with the hemoglobin in our body‚ depleting the cells of incoming oxygen and one can turn blue‚ this is also called the “Blue Baby Syndrome”

The International Agency for Research on Cancer(IARC) is a group of scientists and experts who scrutinize the overall evidence on how likely things are to cause cancer. This agency recently announced that processed meat is a carcinogen‚ this announcement is backed by over 800 studies done to link diet to cancer(Dunlop). Processed meat is defined as any meat preserved by smoking‚ curing or salting‚ or with the addition of chemical preservatives; examples include bacon‚ salami‚ sausages‚ hot dogs or

of N-nitrosamines depends on the organs. For example‚ their targets for cancer in rodents include thyroid‚ pancreas‚ urinary bladder‚ trachea‚ lung‚ oral and nasal cavities‚ esophagus‚ kidney and liver. With respect to N-nitrosamides‚ skin‚ bone‚ peripheral nervous system‚ brain‚ small intestine and glandular stomach are targeted organs for cancers. Besides cancer‚ acute myelocytic leukemia and T and B cell lymphoma have also been triggered by N-nitrosamides. In table 8.1‚ some N-nitrosamines and

It can react with secondary amines to form nitrosamines. Research has shown that some nitrosamines can cause cancer (Mygind‚ 1991). Furthermore‚ in our blood there is a reaction between nitrite and haemoglobin. Nitrite can oxidise the haemoglobin in the blood to methaemoglobin which is incapable of binding with oxygen and

Food additives are in most of the things we eat. Most People consume food additives every day in all the foods they eat. There are many additives used that people know about and many that the average person has no knowledge about. This paper will give you a greater understanding which food additives are common and what effect it has on your health. According to the U.S. Food and Drug Administration (FDA)‚ a food additive is any substance added to food. Legally the term means‚ "any substance the
