GlucholSalt, food and blood-pressure-related dietary impact
Understand salt and sodium in packaged foods and restaurant meals, and why dietary estimates cannot measure or diagnose blood pressure.
Can an app measure blood pressure from food?
No. Food analysis can describe dietary factors associated with blood pressure, but it cannot measure your blood pressure or predict an exact reading after eating. Gluchol's dietary-impact output is not a replacement for a validated blood pressure monitor.
Salt, sodium and food labels
The NHS advises adults to have no more than 6g of salt a day, including salt already present in food and added during cooking or at the table. This is general UK adult guidance, not an individual prescription.
Sodium and salt are related but not identical label quantities. Salt is approximately sodium multiplied by 2.5 when expressed in the same units. Check whether a label gives grams of salt or milligrams of sodium before comparing products.
Restaurant meals and practical comparisons
Sauces, dressings, cured meats and packaged ingredients can add salt. Ask for available restaurant nutrition information and compare portions and sides. A missing sodium or salt value does not mean a dish is low in salt.
The NHS recommends checking labels and using herbs, spices or other flavourings instead of extra salt where appropriate. If you have medical dietary restrictions, follow your healthcare team's advice rather than relying on a general food comparison.
