Bottom line
If you feel you might benefit from adding some sources of protein into your diet, be sure to talk with your doctor before making any drastic changes. Increasing your protein consumption will not be a silver bullet to keeping your body healthy as you age. Staying physically active is also important to help maintain your health and live your best life.
Beans and legumes, including all types of dried beans, split peas and lentils, are considered good sources of protein.
