How does aging generally affect nutrient absorption?

As individuals age, various physiological changes can impact nutrient absorption, and a notable effect is a decrease in digestive efficiency. With aging, the production of digestive enzymes may decline, and the stomach's ability to produce acid can also be reduced. These changes can impair the breakdown and absorption of nutrients from food, leading to potential deficiencies if dietary adjustments are not made.

Additionally, aging can affect the intestinal lining and its ability to absorb nutrients effectively. Factors such as decreased motility within the gastrointestinal tract and alterations in gut microbiota also contribute to this decline in efficiency. Overall, these age-related changes highlight the importance of monitoring nutritional intake and making dietary modifications to ensure that older adults receive adequate nutrients for maintaining health.
