Eating healthy is one of the easiest ways to boost your energy levels, because foods provide the macro- and micronutrients needed to power your cells. Yet in 2015 less than 14% of Americans over 40 ate the recommended number of servings of fruit each day. For vegetable intake, it was worse—less than 11% hit this target.
Harry says that as we get older, our ability to absorb certain nutrients from our food can also decrease, such as vitamin B12, which is needed to convert food into energy. Vitamin B12 deficiency is common among older adults, but vegans and vegetarians who don’t take B12 supplements are also at risk.
In addition to eating healthy, physical activity “can go a long way to [keeping] us vibrant and energetic as we get older,” says Harry. However, in 2015 only about 23% of adults ages 18 to 64 got enough aerobic and strengthening exercise each week.
