Canned tuna in water — extremely lean protein, shelf-stable, cheap.

Best protein-per-dollar at most grocery stores. ~70 kcal/can with 16g protein. Mercury concerns limit to 2-3 cans/week for most adults.

Best for

  • cutting or high-protein days — 26g protein / 100g at 116 kcal
  • meals where you want volume of protein without a fat bomb

Watch out

  • restaurant versions that are breaded, sauced, or cooked in oil — the log is for the plain item
  • weighing cooked vs raw without matching the database state

How to log it

Prefer weighing canned tuna (in water) after cooking if that is how you eat it, or stick to one convention. 1 can (5 oz) (~142g) is the practical unit in the app.

Where it fits the day

Fits as the protein anchor. Pair with a carb and produce so the plate is not only lean protein and boredom.
