What It Is

nutritionalassessment.org primarily hosts the online revised content for the 3rd edition of Principles of Nutritional Assessment. The main text indicates that this edition is a major revision of R.S. Gibson’s Principles of Nutritional Assessment, published in 2005, and that more than thirty chapters or subsections are already freely available. As such, it is closer to an open online textbook or professional reference work than to a traditional online course with classes, assignments, and certificates.

Core Content and Format

The content covers the core framework of nutritional assessment: food supply and individual intake, food composition and bioavailability, dietary assessment errors/reproducibility/validity, nutrient reference values, diet quality, anthropometry, body composition, laboratory methods, biomarkers, and the assessment of specific nutrients such as protein, iron, vitamins A/D/E/C, B vitamins, calcium, zinc, iodine, and selenium. The introductory section also systematically explains four types of assessment systems—nutrition surveys, nutrition surveillance, nutrition screening, and nutrition interventions—and discusses newer developments such as DHS, NHANES, WHO guidelines, POCT, e/m-Health, and personalized nutrition.

Pricing and Certificates

The main text explicitly mentions that multiple revised chapters are “freely available,” so the core reading content appears to be open access. No information was found about paid subscriptions, course purchases, payment methods, completion certificates, or credit accreditation.

Pros and Cons

Its strengths are its high academic depth, comprehensive chapter structure, and extensive references to public health nutrition practice and research literature, making it suitable for serious study of nutritional assessment methods. It is especially valuable for scenarios such as nutrition surveys in low- and middle-income countries, clinical nutrition screening, and monitoring and evaluation of intervention programs. The drawbacks are also clear: the site is presented as a long-form English textbook, so the learning barrier is relatively high; there are no videos, quizzes, assignments, instructor Q&A, or learning community; and the 3rd edition is still under revision, so its completeness may change as chapters are updated.

Who It’s For

It is best suited for students, researchers, and practitioners in nutrition, public health, epidemiology, and clinical nutrition, as well as people who need to design nutrition surveys, screening programs, or intervention evaluation plans. It is less suitable for general learners who want beginner-friendly video courses, Chinese-language explanations, or certificate-backed learning.

Access in China

The main text does not provide information about access from mainland China, so it is not possible to determine whether the site can be accessed directly and reliably. Actual access testing is recommended.
