The most important characteristic of a healthy diet is balance of food types, and of intake and output. Low protein intake is associated with a higher risk of bone fracture. There is controversy about whether high animal protein intake increases the risk of fractures in women. Menopausal women are at increased risk for osteoporosis, especially if they are Caucasian and/or thin. The best calcium source is dairy products. Three servings provide the recommended daily allowance of 1000 mg. With fewer women taking hormone replacement therapy, more women are looking for alternatives to control menopausal symptoms, particularly hot flashes. The type of natural product most commonly used for menopausal symptoms are phytoestrogens or plant estrogens. Eating disorders are most commonly associated with younger women: teenagers and young adults. The recommended diet for people with diabetes should contain carbohydrate, protein, and fat in reasonable proportions.
