Near as anyone can tell — not that there's a big difference — Satchel Paige was around 41 or 42 when he signed with the Cleveland Indians in 1948. In his rookie season, he went 6-1 with a 2.48 earned run average. By the time he left the Majors in 1953 at 46 (give or take), he had pitched 59 games with a 3.29 ERA in the bigs. (He made a single start in '65 at 58ish, going 3.0 innings with 1 hit allowed.) As one of the all-time greats who spent the prime of his career segregated from the Majors, he was inducted into Cooperstown in 1971. Perhaps most famous of all, he's remembered for his philosophy on aging: 'If you don't mind, it don't matter.' That was clearly true for Satchel Paige. The rest of us likely aren't that lucky. As Abbott's Pam Nisevich Bede and Steven Hertzler know well, minding your diet and protein intake sooner than you might think you need to can matter a great deal to how your body ages. The 'Pro' in Protein The impact of better and more purposeful nutrition matters across all of life's stages. Yet with each passing year, consuming adequate amounts of protein and nutrients becomes more critical. Eating for longevity becomes a double edge sword: Our nutrient needs increase yet we become less proficient in putting these nutrients to work. 'We become less efficient at utilizing protein as we age,' said Bede, a registered dietitian and member of Abbott's Nutrition Scientific and Medical Affairs team. 'In fact, starting as early as age 40, we can start to lose up to 10% of our muscle each decade. In early adulthood, we need to start prioritizing protein because otherwise muscle loss can be a concern as the effects of aging set in.'
