balanced diet, crazy...

i interpreted for a chinese woman at the clinic today. she has diabetes and kept telling me what a great diet she is on. everyday she drinks a glass of milk in the morning, then eats some veggies (mainly broccoli) for lunch, and then drinks a glass of milk before bed. that's it. she says absolutely no meats. WHA!? i felt bad because she has been so nervous about being diagnosed with diabetes that she's been on this strict diet. but it's all wrong. i tried to explain to her that she needs a balanced meal, with all food groups: carbohydrates and protein included. she didn't believe me. argh.
