Some things to include might be vegetarian meals, veggie salads, pizza with veggies, raw veggies, soups, fruits, green juices. I've read that people with diabetes can have a problem converting carotene in foods to Vitamin A, so a supplement would help.

Other good supplements include Vitamin C with bioflavanoids. Green tea, other herbal teas, olive oil, Coenzyme Q10 which is good for the heart as well. Vitamin E complex is the best type of E (Swansonvitamins.com sells it at a discount); also a good vitamin and mineral supplement and filtered boiled water.
If any meat, it might be a small amount, or organic chicken, maybe a little beef but not much, Chinese food without the additives like msg, fish like salmon etc.

And kale, beets, potatoes, whole grain foods like brown rice, cornmeal, oats, beans (incl. lentil soup), dates, nuts (especially almonds), organic cow's milk and yogurt, olive leaf extract, echinacea capsules, fennel seed capsules, calcium and magnesium (she's also had calcium injections, but this would be only under a doctor's order), maybe acidophilus especially after taking antibiotics. There are so many dairy products to choose from, and also calcium even found in carrots and certain greens, that too much calcium in supplements is not needed.

Also walking, fresh air, etc. Watch out for herbs, as some of them can be toxic in large doses, not good for those who are pregnant, for the allergy prone, etc. It would be good to have a reference book on them, or do searches to find out what the side effects might be before taking any.
