How processed meat causes cancer – During cooking processed meat produces heterocyclic aromatic amines as well as other chemicals including polycyclic aromatic hydrocarbons . These chemicals are suspected carcinogens. When you consume it , cancer causing compounds start residing in our body.

How does red meat causes cancer – In red meat problems seem to start when a chemical called haem – part of red pigment in the blood haemoglobin is broken down in our gut to form a family of chemicals called N nitroso compounds. These have been found to damage the cells that line the bowel  . So other cells in the bowl lining have to replicate more in order to heal and it’s this extra replication that can increase the chance of errors developing in the cells DNA.  This is the first step on road to cancer .

Studies also show that people who eat a lot of red meat are found  eating fewer plant based foods. So they benefit less from their cancer protective properties.

How to avoid cancer -Meat is fine in moderation  quantities , because it’s a good source of protein, iron ,zinc etc.  So its fine to include a moderate intake of 65-100 g of cooked red meat, 3-4 times a week as part of healthy balanced diet .
