The knowledge graph
Everything here connects
This isn't a pile of articles. Each nutrient links to the foods that carry it, the shortfalls it causes, and the people most at risk — so you can follow a thread from a symptom all the way to a $2 dinner.
- 1
Start with who you are — an athlete and an older adult have different priorities.
- 2
That points to your priority nutrients, and the shortfalls worth watching for.
- 3
Each nutrient lists the foods that carry it — priced at every local store.
- 4
Those foods turn into recipes with a real cost per serving.
-

Everything here is general nutrition information, not medical advice. For anything about your own health, talk to a doctor or a registered dietitian.
