How to calculate the salt content of food

Research has shown that reducing average salt intake to 6 grams a day would prevent 70,000 strokes and heart attacks a year.

Some labels do give you the salt content of food per serving, but this currently only applies to a small number of foods; other labels on foods give the amount of sodium in grams per 100g of food.

To convert sodium to salt, you need to multiply the amount of sodium by 2.5

1 gram of sodium per 100g = 2.5 grams salt

You then need to know the weight of the serving portion in grams, then multiply this to work out the amount of salt in the serving.

As a guide a child's salt consumption should not be more than 4 grams of salt a day.

This information is supplied by CASH (Consensus Action on Salt and Health) which is a group of specialists concerned with salt and its effects on health.
