HFCS provides detailed consumption data but is less common, while HCES, more cost-effective, faces challenges in accurately capturing food consumed outside the home. Recommendations for improvement include standardized classification systems and specific data collection methods.

It highlights strategies to improve accuracy, such as using automated reporting tools, shorter recall periods, and standardized coding methods. The importance of thorough data processing and adherence to guidelines is emphasized, alongside studies illustrating the effects of various biases on dietary assessments.

The HEI allocates points for adequacy and moderation, validating its effectiveness in assessing dietary patterns and health outcomes. While primarily developed for adults, adaptations for children exist, and related indices are emerging in other countries.

While it offers high-resolution images, its high radiation exposure and cost are limitations. Innovations like peripheral quantitative CT (pQCT) seek to minimize radiation while assessing bone health. CT is becoming more important in studying sarcopenia, but the absence of clear diagnostic standards hampers its clinical use.

Fat acts as an energy reserve, with subcutaneous and visceral types, the latter linked to higher health risks. Ectopic fat accumulation can further increase disease risks. Muscle, part of fat-free mass, is crucial for health, and its loss is harmful, particularly in malnutrition and aging.
