It is common for manufacturers to include large amounts of information that is not required by law (descriptions of the taste, for example); this is referred to as ‘voluntary information’.
You can include as much voluntary information as you please, provided it is not false or misleading; however, you cannot do so at the expense of mandatory information.
If you find that you have no room for mandatory information (or would have to use a font size that is too small, or not use the required format) because you have given label space over to voluntary information, then the voluntary information will either need to be removed or reduced.
