Longevity is the achievement of a long life. We may hope for longevity so that we can experience many years of quality time with loved ones or have time to explore the world. But living to a ripe old age doesn’t necessarily mean healthy or happy longevity if it is burdened by disability or disease.
Healthy lifestyles are associated with better cognitive function in older adults — even those whose brains show signs of dementia, according to research published in JAMA Neurology last month. The study suggests a healthy lifestyle could buffer older adults against cognitive decline and boost their “cognitive reserve.”
As we age, our bodies change in many ways—inside and out. Metabolism tends to slow down, and muscle mass may diminish. These sorts of changes can affect how we process and use nutrients from the food we eat. It’s important to be aware of these changes and how they might affect your personal nutritional needs.
