Based on my experience conducting systematic reviews and book chapters, I help researchers plan and write systematic reviews in nutrition, chronic disease, functional foods, and related health topics. This includes defining focused research questions, developing search strategies, screening and organizing articles, structuring PRISMA‑style sections, and supporting narrative synthesis of findings. The service is ideal for M.Sc., Ph.D. scholars, or early‑career researchers who have basic data ready but need guidance in methodical organization and writing; I do not perform full literature searches on behalf of ethics‑bound projects but guide and support you through each step.
