The CBP website is quite clear and permits your friend to click on the specific type of product. What it does not answer are the also details not in your OP such as the specific location where the product is manufactured and purchased and where in the US it is destined.

Emailing is not the way to go here. Your post is a bit confusing because you say that this for a friend, but it then shifts to the first person. So, whether it is for you or for a friend, call CBP and ask about the specific products and provide the specific destinations.

As you note, even if permitted, on your Declaration, whether paper or electronic, there is a yes/no box for food and you must check "yes" for food if you have any even if it is permitted.
