regards dukan vegetarianism....
Dukan says:
"So how can we be a vegetarian? It all depends on how this word is defined. If it means just cutting out all red meat, there are many other sources of animal protein such as fish, seafood, eggs and dairy products that can provide an ample intake.
If it means not eating anything from an animal that has been raised and slaughtered for us to eat then it becomes more difficult, as this leaves only eggs and dairy products, but this is possible and sufficient for people who are not trying to lose weight.
If vegetarian means only eating vegetables, my diet becomes very hard to follow as there is no other choice but to use incomplete vegetable proteins that have to be very cleverly teamed up with cereals and leguminous plants to ensure that all amino acids are consumed because without all of them it is impossible to produce vital proteins."
hope this helps x
