Nutrition refers to the consumption of food and drink and the process of breaking down and using nutrients as fuel for fueling our bodies. Nutrition plays an integral part of healthy aging by supporting weight management, strengthening immune responses and maintaining bone and muscle health. A diet rich in fruits, vegetables, lean proteins and whole grains should be consumed along with water consumption to stay hydrated; also choose unsalted or low-sodium options when selecting meals and drinks.
Macronutrients – carbohydrates, proteins and fats – form the cornerstones of a nutritious diet. Older adults may require lower calorie needs but similar or even increased nutrient requirements than younger people due to decreased physical activity and changes in metabolism. Calcium, zinc, iron and vitamin B9 are essential in supporting immune function and maintaining bone health; protein malnutrition from poor diet is associated with muscle atrophy and functional decline.
Not only is having a healthy diet important, but social interaction also plays a key role in keeping older adults in good health. Volunteering, joining a book club or enrolling in academic courses are great ways to meet people and build social capital – these interactions may also help enhance mental and emotional wellbeing and reduce depression risk. Regular visits to healthcare providers for screenings or checkups is essential to detect any potential health problems as they arise.
