Salt, water and potassium describe different parts of the diary, and Calk reads each of them on its own.
Salt Pattern#
What Calk calculates. Calk estimates salt from all recorded foods and compares the daily average with your salt limit. When the average is over the limit, the card lists up to three foods that supplied the most salt, each with its grams per day. 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 first food on the list. 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. The potassium card works like the mineral cards: Calk compares the recorded daily average with the reference for your age and sex, and the card appears when food alone reaches it. 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.
