Dr. Dennis Goodman, an associate professor of cardiology at New York University and the director of integrative medicine at New York Medical Associates, advocates magnesium-rich foods. His recent book, Magnificent Magnesium explores the mineral's many health benefits which include increased heart health, better sleep, and stress-reduction. With a healthy serving of bananas and spinach, this smoothie contains more than half the recommended daily intake of magnesium, as suggested by the FDA, and is only 210 calories.
