Food for Thought
For older adults, healthy balanced nutrition can be a major factor in determining overall quality of life. Yet for many older adults, getting all the necessary nutrients for optimal health can be a challenge. According to the National Resource Center on Nutrition, Physical Activity and Aging, malnutrition in older adults is highly prevalent amongst older adults living in their own homes, in long-term care facilities, and in hospitals. A 2013 study published in “Osteoporosis International” found malnutrition, especially inadequate protein, to be a major contributing factor to muscle wasting, and loss of strength. As fitness professionals, we need to be aware of the nutritional obstacles faced by our older adult clients so that we can help them achieve peak health and optimal daily function.
Many physical changes take place as a direct consequence of aging that can affect nutritional choices. Dental problems can make chewing difficult, causing older adults to steer clear of foods like meat and raw produce. Diminished senses of taste and smell can make food seem less appetizing. Poor prostate and bladder function, combined with reduced ambulatory function, can be a deterrent to staying hydrated, as every trip to the bathroom becomes a challenge. Reduced strength and diminished reaction time can make cooking and food preparation a chore.
In addition to natural physical changes, many other factors can keep older adults from eating well. Medications can affect the taste and smell of foods, making them seem unappetizing. Chemicals and preservatives in processed convenience foods can interfere with digestion and vital organ function, and microwave ovens can deplete nutrients. Antibiotics in animal products and medications can disrupt digestive intestinal flora, causing upset stomach, constipation and diarrhea. Poverty among older adults is also a critical component of malnutrition.
Despite the many obstacles faced by older adults, getting essential nutrients can be simple. A daily smoothie made from whole ingredients like bananas, berries, greens and organic Greek yogurt can provide a wide range of vitamins, minerals, enzymes and protein. Ingredients can be prepared and frozen in meal-sized portions, ready to be blended. Organic peanut butter on whole grain bread can provide protein and healthy fat. Organic free-range hard boiled eggs are a rich source of protein and nutrients. The yolks contain lutein for eye health, and egg yolks are a rich source of vitamins A, B and D. Plain organic yogurt is an excellent source of protein and digestive enzymes. A probiotic supplement may help improve digestion.
Understanding the needs and physical limitations of older adults is important for trainers who wish to tap into this lucrative and growing market.
