Meat is a good source of key nutrients like zinc, protein and vitamin B12, they point out, as well as iron, which humans absorb more easily from meat than from plants.
"This decision doesn't mean you need to stop eating any red and processed meat," said Tim Key, an epidemiologist at Cancer Research UK.
"But if you eat lots of it, you may want to think about cutting down. You could try having fish for your dinner rather than sausages, or choosing to have a bean salad for lunch over a BLT (bacon, lettuce and tomato sandwich)."
I was a vegetarian for a good number of years _ or rather a pescatarian, I should say. Since going back to meat eating, I rarely eat red meat. Took a liking to turkey sauces recently, but I think it's better avoid processed meat as much as possible.
