Well, my mom is forced to to grain-free against her will -- she has a really bad ulcer. We didn't know what it was and it got worse and worse, and finally someone at work told her it sounded like an ulcer. She was reading that grains make it worse, and she got really overwhelmed at having to change her diet. She usually eats oatmeal for breakfast, hummus on rice cakes for lunch with creamy tomato soup, and some kind of simple dinner, like an omelette.
Now she can't have grains, or milk, or acid fruits like tomato, and can't have heavy meats either, so basically she's a lacto-ovo Primal vegetarian now. (Cheese is fine, but milk is not.)
I drew up a sample meal plan for her to show her what she could eat so she wouldn't be so overwhelmed, like a spinach and cheese omelette with a side of stewed pears for breakfast, a veggie frittata with sides of fried plantains and roast broccoli, and a dinner of a baked sweet potato with cabbage slaw on the side, and banana and almonds for a snack.
I had like three jars of sauerkraut in the fridge, so I strained out all the juice and gave it to her, as it is supposed to be incredibly healing for ulcers. She said it was delicious. We went to the store and she got lots of aloe vera juice too. I cooked and peeled hard-boiled eggs for her to eat for breakfast tomorrow, so she doesn't have to think about it.
I told her if she'd like I could meal plan and cook for her at first, so she could learn what foods were available to her without having to do it all by herself. I enjoy cooking, I don't like to see her in pain, and I do like to see when a food seems good for her, like the sauerkraut juice.
I hope she has much healing at the end of all this, and greater energy as a result.
