I have been trying to lose weight and eat less fattening foods. That is going well for me. However, my friend stated that I should not eat my salad with vinegar. I do not use dressing and I like just vinegar. She says that it will mess up my teeth since I eat to many salads now. I am not sure about this since I seem to recall someone else saying something like that too. I am doing very well with my weight and I am feeling better about myself. I do not want to start having teeth problems now. What do you think? Any advise please.
