Salt, water and potassium describe different parts of the diary. Calk keeps them separate, then combines them only when the recorded pattern supports a useful comparison.
Salt Pattern#
What Calk calculates. Calk estimates salt from all recorded foods, compares the daily average with the current reference and identifies a repeated source when one is clear. WHO recommends less than 5 g of salt a day for adults, equivalent to less than 2 g of sodium World 2012.
The estimate depends on the food data. Restaurant recipes, seasoning added at the table and products with an incomplete label can make it less certain.
What you can do. Start with the named contributor. Bread, cheese, processed meat, sauces, ready meals and restaurant food can contribute more than the salt shaker. Compare a lower-salt version, change frequency, reduce the sauce or keep the food and adjust another repeated source.
Water Intake#
What Calk calculates. Calk adds the water contained in recorded food and drinks. It also checks whether beverages were entered on enough complete days to support an interpretation.
If drinks are rarely recorded, the app reports a logging gap. Food records cannot assess hydration status, fluid losses, climate, illness or medical fluid restrictions.
What you can do. If you want this view to be useful, record the drinks you normally consume. Use medical advice for fluid targets when kidney, heart or endocrine conditions, pregnancy, medication or intense heat and exercise make general guidance inappropriate EFSA 2010.
Potassium Sources#
What Calk calculates. Calk counts complete days containing a meaningful food source of potassium and shows familiar or new options from the ingredient catalog. WHO suggests at least 3,510 mg of potassium a day for adults World 2012.
What you can do. Add a source that fits an existing meal: potatoes, beans, lentils, leafy greens, fruit, dairy or fish. Do not use a potassium supplement or salt substitute without medical advice if kidney function, medication or another condition can affect potassium handling.
Salt and Potassium Together#
What Calk calculates. This result appears when recorded salt is high, potassium-rich foods appear infrequently and the diary contains a clear salt source plus realistic potassium options.
What you can do. Work both sides if appropriate: reduce one repeated salt source and add one ordinary potassium-rich food. The two actions serve different purposes; adding potassium does not erase a high salt intake.
