About this record

WHO recommends limiting sodium intake to less than 2 g per day, equivalent to 5 g of salt. Since 1 g of sodium corresponds to roughly 2.5 g of salt, the two figures express the same limit — food labels usually report sodium while policy documents usually use salt.

Figures for this record

Four sources, one unit: grams of sodium per dayWHO (global) · tbm-0172.0EFSA (EU) · tbm-1972.0US Dietary Guidelines · tbm-1292.3China Dietary Guidelines · tbm-1262.0Unit: g/day (sodium)
One dietary limit, four sources — why the numbers differ
China's guideline says 'salt under 5 g/day'; WHO (record tbm-017) states that 1 g of sodium ≈ 2.5 g of salt, so 5 g salt ≈ 2.0 g sodium/day. Sodium and salt are two labels for one limit — mixing them up is the most common misreading.

Look up confidence / source / as_of by record ID — all records on this page can be verified this way.

Reuse this work

Text, figures and structured data on this page are free to reuse (including commercially), under two conditions:

  1. Attribution: credit "Source: Trustbase Lab" and keep a link to https://trustbaselab.com/en/record/tbm-017/;
  2. Keep the identifiers: when citing a single fact, keep the record ID, as_of and confidence grade — they are the carriers of verifiability. Remove them and the citation loses its point.

Figures are generated at build time as inline SVG from our own data (data.json) — no external chart services, reproducible offline. Upstream third-party sources (UN Comtrade, EU official journals, ISO, WHO and others) remain the property of their respective rights holders; this page cites them factually and attributes them.
