Aging is something every one of us experiences, but how we age is influenced by much more than the number of candles on our birthday cake. Our bodies change over time. Muscle mass can gradually decline. Bone health becomes increasingly important. Appetite may change. We may become less active, and our calorie needs may decrease even though our need for many vitamins, minerals, protein, fiber, and other nutrients remains important.

When people talk about nutrition, certain nutrients tend to get all the attention. Protein is discussed for building muscle. Healthy fats are praised for supporting the heart and brain. Vitamins and minerals are often the focus of supplements and wellness conversations. Carbohydrates get plenty of attention—both positive and negative. But there is one incredibly important part of our diet that often doesn't get nearly enough attention: fiber.

Walk into almost any grocery store or health food store today and you will see protein everywhere. Protein bars line the shelves, protein powders fill entire sections, Greek yogurt has become a staple, and food companies proudly advertise the number of grams of protein on the front of their packages. With all of this attention, it's easy to assume that everyone needs to eat as much protein as possible. But is more always better? How much protein do you actually need?
