Altering dietary habits with age is significant, as metabolic processes and nutrient requirements change. As individuals age, they may require fewer calories but a higher intake of nutrients such as calcium, vitamin D, and fiber. Adjusting macros can help manage weight and reduce the risk of age-related diseases. Incorporating more whole foods, fruits, and vegetables while minimizing processed sugars and saturated fats can improve overall health. Additionally, staying hydrated remains crucial, as older adults may experience decreased thirst perception, leading to potential dehydration.
