Let's see, Gout, avoid calcium rich foods; Kidney disease, avoid high protein foods; Diabetes, avoid high carb foods.
Sounds like the perfect time to make a great salad, with a fruity oil and vinegar dressing, and a really good soup, such as split pea (hold the ham), or French Canadien Yellow Pea soup, or maybe a tomato based soup. These will have body without having to rely on starches to thicken (carbs) or flavored broths rich with protein and collagen.
Vegetable stir fries with veggies such as cauliflower, snow peas, water chestnuts, onion, bamboo shoots, bean sprouts, bok choy, or pak choy, seasoned with a little real soy sauce and Chinese 5-spice powder, maybe a little ginger, served with bean thread (cellophane) noodles would work too.
Look on the glycemic index and glycemic load charts to find veggies that will work well for diabetics. The nutrition tables that often accompany those charts will let you know the protein content as well.
You can almost never go wrong with servings of fresh berries, and fruits native to the U.S. Tropical fruits, according to my nutritionist, contain too much sugar.
Hope this helps.
