I don't know if SoL supports custom nutrition (from a quick glance at the CF page anyway), but here's a list of items that I'll keep updated that don't have nutrition groups and what I think it should be
Notes:
A lot of these don't have nutrition auto assigned because they don't have recipes assigned (or in some cases, can't be accessed by JEI)
Some foods are also obtained only by placing a parent food and using a bowl/knife on it (see: guardian soup, plate of dragon leg, stuffed hoglin)
A lot of other foods should be autofixed if they have foods that don't have nutrition groups in their recipes (see: ground strider, nether skewer)
I will also be excluding items that can be eaten, but don't give you hunger/saturation (see: healing stone)
Also, might want to consider adding a nutrition group for dairy? Seems to be a whole lot of it in foods
