Health statistics researcher and coauthor of a 2026 review on confounding in nutrition research
In nutrition research, confounding is an important challenge. Owing to the complexities involved in dietary interventions, such research is often subject to three types of confounders: measured confounders, unmeasured confounders, and time-varying confounders. Inadequate control of these confounders can lead to distorted research conclusions and even undermine the credibility of dietary guidelines.

Disputed The quoted passage appears verbatim in the abstract on the official journal page and in the PDF for "Controlling confounding in nutrition research: Methodological strategies, software implementation, and reporting guidelines," and the official page lists "Published Online: April 16, 2026." However, the source attributes that text to a six-author article—Mujie Shen, Jiawei Zhou, Dongfang You, Fang Shao, Guoshuang Feng, and Yang Zhao—not to Jiawei Zhou alone, so this cannot be verified as a single-author quote under the platform’s rules.
