I've been a vegetarian for many years and so has the mrs. We eat no meat or fish, but do eat/drink milk products. The "vegan" diet without any milk products is very dangerous, especially for children.
Tasty, and very easy to get enough protein, especially if more natural whole foods are eaten and little junk food.
We're happy with it, and we love animals. Especially when they're walking around!
Vegetarianism has a certain appeal for me too. I managed to stay with it for about six weeks,but after that, I did not feel well. A week now and then seems OK.
I need about 18-20 grams of protein at each meal with my veggies--about 3 ounces of meat, 4 ounces of fish, 3/4 cup cottage cheese, or three egg whites. All non-fat. I use very good X-virgin green Italian olive oil for fat plus cod liver oil. Do you use tofu? I try, but find it hard to like.
I had friends who raised the most beautiful white chickens who laid magnificent eggs. They were all named for saints: Saint Agnes, Saint Anne, etc. The chickens were affection trained and would leap into your arms for a cuddle once they got to know you. Chicken has been a little hard to eat ever since.
