I am new to this and understand that we should eat no more than 10g of sugar a day. When reading the food labels how do I calculate this?

Hi Sugar Girl and welcome.
All David said was to make sure there is no more than 3 grams of SUGAR per hundred grams  (or 3%) in any product.

It's really impossible to calculate how much fructose we are eating each day and we would go mad trying!!!! Just keep your fruit consumption down to two small pieces of fruit a day, berries are the lowest in fructose with lots of fiber. Nuts and vegetables do have some fructose in them but it's counteracted by the natural fiber in them.

Usually, on the ingredients list of products, there are the added sugars. Sometimes disguised with other names, like, something will say "no added sugar" but what they have added to sweeten the product, especially in some of the yoghurts, is fruit juice which is even worse. If a product is dairy, the sugars are partly lactose which is fine as it is a form of glucose and is usually about 4% of the sugar on the ingredients list. The rest will be some form of commercially added sugar.

There is always the taste test, if it's sweet, then there is added sugar. Someone made a salad when I went out for a lunch today, at friends, it was so sweet when I tried it, that it felt like it burned my tongue! Naturally I didn't have any.
