Why do our nutrition needs change as we age?
As we age, our bodies become less efficient at absorbing and utilizing nutrients. Metabolic flexibility decreases, and our ability to process energy-dense foods like sugar diminishes. Additionally, appetite and thirst responses weaken, increasing the risk of dehydration and malnutrition.
What dietary changes are recommended for people over 65?
For those over 65, it's crucial to focus on a high-nutrient diet and avoid overconsumption of energy-dense foods. Nutrient-dense meals, such as soups, stews, and dishes with beans, lentils, and whole grains, are recommended. These foods are hydrating, fiber-rich, and help prevent constipation, which is common in older adults.
How does aging affect hydration and appetite?
As people age, their thirst response becomes less efficient, increasing the risk of dehydration. Appetite also tends to decrease, making it easier to rely on ultra-processed foods that are low in nutrients and hydration. This can lead to malnutrition and dehydration, which have severe health consequences for older adults.
What are the risks of relying on ultra-processed foods in later life?
Ultra-processed foods are low in nutrients and hydration, making them unsuitable for older adults. They can lead to malnutrition, dehydration, and constipation, which are particularly harmful in later life. These foods also lack fiber, exacerbating mobility issues and increasing the risk of severe constipation.
How does protein intake need to change as we age?
Older adults need slightly more protein because they become less efficient at absorbing it due to increased insulin resistance. The recommended intake increases from 0.83 grams to about 1 gram per kilogram of body weight. However, this can be achieved through nutrient-dense meals with plant proteins, eggs, or oily fish, rather than excessive meat consumption.
Why is physical activity important for maintaining muscle mass in older adults?
Physical activity is crucial for maintaining or building muscle mass because simply consuming protein isn't enough. Movement stimulates muscle tissue, making it more effective than dietary protein alone. A balanced diet with nutrient-dense foods provides sufficient amino acids, but exercise is essential for muscle health.
