Calcium: For adult women aged 19-50, the USDA recommended daily allowance is 1,000 mg/day. For women over 50, the recommended daily allowance is 1,200 mg/day. Good sources of calcium include dairy products, leafy green vegetables, certain fish, grains, tofu, cabbage, and summer squash. Your body cannot take in more than 500 mg at any one time and there’s no benefit to exceeding the recommended daily amount.
A 45-year-old woman who gets less than 30 minutes of daily physical activity in addition to her normal routine should consume six ounce of grains; two and a half cups of vegetables; one and a half cups of fruit; three cups of milk; five ounces of meat and/or beans; five teaspoons of oil; and just 195 calories of additional fat and sugar. With a higher level of daily activity (30 to 60 minutes), this woman would be able to consume a little more in certain food groups: her fruit intake could rise to two cups; meat and beans to five and a half ounces; oils to six teaspoons; and extra fat and sugar to 265 calories.
