Because of body composition, an increased prevalence of health conditions and the need for medications, and generally less physical activity than our younger selves, the focus for seniors should be more on nutrients versus calories, according to the U.S. Department of Health and Human Services. Specifically, look to add protein, vitamin B12, and plenty of fruits, vegetables, and whole grains like quinoa and oats. And, even though your taste buds may thirst for it, try to stay away from too much sugar, salt, and saturated fats like fatty meats and desserts. Follow these guidelines and you can experience more energy and possibly even a decrease in some chronic condition symptoms.
