Along with physical exercise and maintaining a healthy body weight, it is also essential for the elderly to know about and understand nutrition. Eating well can be a challenge for some seniors. Not knowing how to cook for one or two, decreased senses of smell or taste making food less attractive, or a lack of transportation for grocery shopping are some of the barriers they face. As the body ages, proper nutrition becomes even more crucial for repairing tissue and bones, and keeping the body functioning well. Studies have proven that seniors who maintain a nutritional diet, keep a healthy body weight, and exercise regularly, have better mental and physical energy, leading to a higher quality of life.
