Green beans are the perfect side dish, high in fiber, folic acid, calcium, iron, manganese, copper, potassium and vitamins A, C, K and B6. Skip the can of creamed mushroom and, instead, roast green beans or grill them.  If green beans aren’t your family’s vegetable of choice, try roasted broccoli, also high in calcium. Brussels sprouts are also delicious roasted with some olive oil, garlic and balsamic vinegar. And if you’re making a salad, move away from the standard iceberg lettuce and choose some leafy spinach, which can help protect the brain from Alzheimer’s disease.
