While there are many MS diets, most discourage gluten and dairy. Some also discourage beans and peanuts. My wife has been following this kind of diet for 9 years with no problems. This can easily be done now that gluten free is the new 'in' fad. Gluten free pastas (rice or corn) are usually available at most supermarkets, and are almost indistinguishable from regular pasta. Gluten free breads can also be found at many supermarkets. They are not as tasty as real bread, but some (like Udi's) are pretty good. As for dairy, rice milk tastes pretty close to real milk. Almond milk and flax milk are also options. Rice yougurt can sometimes be found in supermarkets - it's actually quite good. As for cheese, Diaya makes a dairy free, gluten free line of cheese substitutes that are pretty good, especially in a corn tortilla roll-up or gluten free pizza. Other cheese substitutes sometimes contain milk protien (not good). Of course eating a healthy diet with lots of veggies, fresh fruits, and seafood is a no brainer. Good snacks might include nuts, nut butters, fruits, salsa & chips, stuffed grape leaves, smoked salmon, and an occasional chunk of dark chocolate. Eating out can be tricky, but if you like asian food, you can get by. also things like a garden salad with grilled chicken or shrimp will work nicely. If you cheat a little at a restaurant, you are not going to keel over and die!
