Nutrition

Heathy — nutrition data (MCP server)

Nutrition for more than 1,100 whole plant foods and their flours and 39 Ayurvedic herbs, drawn from 30 food-composition tables covering 26 countries plus West Africa, the Pacific and FAO's global biodiversity table — including IFCT 2017 (India). It also answers which GB/EU and US nutrition claims the published data supports for a raw whole food or an unfortified flour.

What makes it different

Most nutrition APIs hand back a single number from a single national table. This one returns the number *and its provenance*:

• the median across the datasets that have the food,
• how many sources contributed and which ones,
• the min–max spread between them, and every source's own value.

So an agent can cite a figure instead of asserting it, and can tell when the sources disagree. Guava vitamin C, for example, comes back as 222 mg — the median of 13 tables, ranging 68–273 — with 20 national values listed side by side. That spread is real: soil, cultivar and analytical method differ between countries, and it is worth knowing before stating a figure as fact.

Indian foods are covered from IFCT 2017, so questions about karela, horse gram or millets are answered from Indian data rather than a US substitute.

How far the cross-checking goes

Be aware of coverage when you use the data:

• Fewer than half the foods are held by two or more tables — up to 26 for common produce.
• More than half come from a single table. Their sources count is 1; there is nothing to cross-check them against. Use min_sources on nutrient_ranking to keep these out of a ranking; they are then listed beside it.
• Some tables' licences allow their figures to be shown but not averaged. Those values appear under by_source but are not folded into the median, which is why sources can be lower than the number of values listed.

Tools

lookup_food

Full per-100 g nutrient profile for a whole plant food or flour, with provenance.

The full profile covers about 130 nutrients, plus a research tier marked tier: "research" (thin coverage, or a restatement of another nutrient).

What comes back when the name is not an exact match:

• An everyday name ("potato", "kela", "besan") opens the food most national tables carry. When the match was loose, the answer says so in matched_from, with the other foods it could have meant.
• Everyday nutrient names ("fiber", "omega 3", "calories", "vit c") are understood. A name that is not is listed in unrecognised_nutrients; the rest of the answer is returned.
• A cooked or prepared form ("lentils boiled", "brown rice cooked") is refused, and the reply names the unprepared food that is held. The unprepared figures are not returned in its place: per 100 g they are a different food.
• A food that is not held — animal foods, foods made from plants (tofu, pasta, sugar), refined wheat flours — gets a reply saying which of those it is.

search_foods

Resolve a name to a slug, including Hindi, Sanskrit and botanical aliases. Returns ranked candidates for a plain-English or local name.

nutrient_ranking

Rank foods by a nutrient per 100 g — the "highest in iron" question. Each row also gives the typical serving heathy.org holds for the food and the amount in it; the order is per 100 g.

Foods eaten a few grams at a time — dried herbs, spices, tea leaves, and dried seaweed, mushrooms and vegetables, 102 foods — are not ranked in results. They are reported beside it in also_higher.small_amounts: a count of those holding more per 100 g than the last row, and the first five. They are ranked in results when include_small_amounts is true, and when the category asked for is mostly such foods (spice, tea, seaweed).

herb_monograph

An Ayurvedic herb monograph. Traditional use and modern research are kept strictly separate — traditional records what the tradition claims, modern records what research shows with an evidence tier. Every response carries a mandatory `safety` block (cautions, pregnancy guidance, drug interactions).

check_claim

For a raw whole food or an unfortified single-ingredient flour, which nutrition claims ("source of potassium", "high in vitamin C") the data supports under GB/EU rules (Reg. 1924/2006, per 100 g) and US rules (21 CFR 101.54, per RACC). It flags where the answer depends on which national table was used, listing the tables that do and don't support it.

Scope. This is a screening tool, not permission to make a claim. It refuses cooked and manufactured products, whose composition depends on recipe and processing. A supported claim still needs an analysis of the producer's own produce: the law looks at the final product, not at a reference table. It lists the tables that do and do not support a claim; it does not choose one that qualifies.

search_recipes

Find original raw / no-cook vegan recipes on Heathy by free text, health goal, category, ingredient, time or allergen. Per-serving nutrition is computed from the same food rows lookup_food returns.

get_recipe

One recipe in full: ingredients with food slugs and gram weights, method, per-serving nutrition, allergens and carbon footprint.

health_topic

What to eat for a health goal — the nutrients involved, why each one, and which raw recipes carry them. Accepts a goal ("gut health") or a named condition ("PCOS", "anaemia"). Topics people reach for with a diagnosis carry a note on what the evidence does and does not support, with its own evidence rating. Omit topic to list every topic.

Examples

Response shape

Every tool returns the same envelope:

{

"data": { /* the payload */ }, "attribution": ["USDA FoodData Central …", "IFCT 2017, ICMR–NIN …"], "source_url": "https://heathy.org/food/guava-flesh-only-raw/", "disclaimer": "Informational only — not medical advice.", "license": "https://heathy.org/terms/" }

Each response includes attribution, disclaimer and source_url; herb responses also include a safety block with cautions, pregnancy guidance and drug interactions. The terms at https://heathy.org/terms/ ask that figures you republish carry the attribution.
