The Nutritive Value of Indian Foods (NVIF 1989) provides nutrient composition for 592 key foods. Food composition values were measured by National Institute of Nutrition, Hyderabad. You can ask about composition of 592 key foods in India here: nvif1989.github.io.

Shown below is a text-query javascript API for search information through these tables. However, you may also add these to a database for more control over the query.

```javascript const nvif1989 = require('nvif1989');

async function main() { await nvif1989.compositions.load(); await nvif1989.codes.load(); nvif1989.columns.load(); nvif1989.groups.load(); /* load corpus first */

// NOTE: grup is wrong, curd is wrong nvif1989.compositions('pine apple'); nvif1989.compositions('ananas comosus'); nvif1989.compositions('sapuri'); nvif1989.compositions('294'); // [ // { // code: '294', // name: 'PINE APPLE', // scie: 'Ananas comosus', lang: 'B.
