High protein content has become a selling point on foods ranging from breakfast cereals to yoghurts. For anyone hoping to build muscle or stay strong as they age, choosing the product with the most protein can seem sensible. But whether an extra serving will help depends on what they already eat and how they use their muscles.
Someone who regularly lifts weights may benefit from additional protein to support muscle growth. An older person with a small appetite may need help getting enough to maintain strength. Someone already eating enough protein may gain little from adding more.
