Why do kcal requirements tend to diminish after the age of 25? Why do nutrient requirements not diminish at the same time? Answer should be based on nutrition throughout lifespan

Answer 1

As people age, their metabolism tends to slow down, which can lead to a decrease in calorie requirements. This is because older adults tend to have less muscle mass and lower levels of physical activity, which both contribute to a lower energy expenditure. In addition, hormonal changes and other age-related factors can also play a role in decreasing calorie needs.

On the other hand, nutrient requirements do not diminish at the same time as calorie requirements because the body's need for essential nutrients remains constant regardless of age. In fact, nutrient needs may even increase in older adults due to factors such as decreased absorption of certain nutrients, changes in body composition, and higher risk of chronic diseases.

Therefore, it is important for older adults to focus on nutrient-dense foods that provide essential vitamins, minerals, and other nutrients needed for overall health and well-being. Meeting nutrient requirements through a balanced diet can help support healthy aging and reduce the risk of age-related diseases.
