The only crossword study book designed specifically for the Dietitian board exam
Tired of re-reading the same dense notes? Puzzle Your Way to RD Success by Registered Dietitian Merisa Martinez, RDN transforms exam preparation into an engaging, effective active-recall experience. Every puzzle maps directly to a real RD exam knowledge domain — so every minute you spend puzzling is a minute spent mastering exam-ready terminology.

Traditional RD exam prep often means staring at the same pages until the words blur. Puzzle Your Way to RD Success takes a fundamentally different approach — rooted in the science of active recall — and makes it genuinely enjoyable.
Written by Merisa Martinez, RDN at Live Nourished Today , every crossword was crafted to mirror the depth and clinical context of the actual RD board exam. This isn't trivia — it's targeted mastery.
Retrieving a term from memory under constraint creates far deeper encoding than re-reading flashcards or notes — the same cognitive process activated during your actual exam.
Clues use clinical framing, disease-specific contexts, and dietary reference language — not vague definitions. Written by someone who has sat the exam and works in practice daily.
Travel-sized paperback means you can study on your commute, between rotations, or anywhere your dietetic internship takes you — without draining your phone battery.
Puzzle-based studying has been shown to reduce cognitive fatigue while maintaining focus longer than traditional study formats — so you absorb more per session, every session.
Unlike generic crossword books, every puzzle in this collection was built around the knowledge areas tested on the NDTR and RD board exams. Pair it with personalized nutrition counseling to reinforce clinical application beyond the exam.
Disease-specific protocols, enteral & parenteral nutrition, nutrition assessment, biochemical markers, and therapeutic diet modifications for clinical conditions.
Macronutrient metabolic pathways, enzymatic functions, nutrient interactions, digestion and absorption mechanisms, and energy metabolism fundamentals.
Food composition, preparation methods, HACCP principles, food labeling standards, food safety regulations, and the science behind quality and preservation.
Fat-soluble and water-soluble vitamins, major and trace minerals, deficiency and toxicity conditions, DRIs, food sources, and clinical significance on the exam.
Federal nutrition programs (WIC, SNAP, MNP), nutrition guidelines, population health assessment, health disparities, and public health nutrition interventions.
Motivational interviewing, behavior change models, nutrition education strategies, counseling theories, and communication frameworks used in everyday dietetics practice.
Cognitive science is clear — active retrieval builds stronger, longer-lasting memory than passive review. Here's how this book puts that into practice, one puzzle at a time.
Each clue presents a clinical concept using the framing and language of real RD exam questions — not beginner definitions.
You search your memory for the exact term — including correct spelling. This retrieval effort is what drives deep encoding into long-term memory.
Crossing answers force you to verify answers using intersecting letters — requiring simultaneous recall of multiple nutrition concepts.
The included answer key lets you confirm and correct immediately — closing the feedback loop that cements lasting recall before exam day.
Crossword puzzles aren't just fun — they're a scientifically validated form of cognitive exercise. Research consistently shows that puzzle-solving strengthens memory, sharpens focus, and reduces mental fatigue — all essential qualities for high-stakes exam performance.
Studies published by UPMC Health Beat confirm that regular crossword puzzle activity strengthens neural pathways related to vocabulary retrieval and pattern recognition. Research from All Seniors Care further demonstrates that puzzles improve working memory and sustained attention — both critical for multi-hour board exams. And Progress Lifeline notes that puzzle-solving actively builds new cognitive connections, making information easier to retrieve under pressure.

"A creative and genuinely effective study tool. I use it alongside my traditional RD exam review books and I actually look forward to this one. The clinical clues are surprisingly well-aligned with what actually shows up on the exam."
"I was skeptical that crosswords could actually help me study. The MNT section alone covers terminology I'd been blanking on in practice tests. The fact that it's written by a real RDN makes a noticeable difference — the clues actually sound clinical."
"Bought as a gift for a friend in her dietetic internship and she absolutely loved it. Such a thoughtful and genuinely useful exam prep resource. Breaks up the monotony of studying in the best way. Will be buying copies for our entire cohort."
