I have a friend who went on a vegan diet and is having fainting spells. She is ghostly pale and I told her she needed iron in her diet. She has refused to go to the doctor and I am really concerned about her. What advice can you give me?Thanks Tracey, that was what I was thinking. This vegan diet has caused her to become anemic.I got her to eat a little meat and drink some dairy milk and she said she feels better. It appears it was the vegan diet that made her sick and weak.
