Partner is making BLW difficult

We’ve been doing BLW for 2 weeks now, since bub turned 6 months old on the dot. We are using the solid starts app which has been amazing. My partner has been really controlling over what to give our baby, however. I’m happy for bub to try a range of things, especially vegetables. My partner has said no to potato and sweet potato (“too much starch”), no to any wheat or oats (“until baby’s first molars come in”), no to broccoli, carrots, cheese (basically any food that is “not iron rich”) and no to most fruits except for strawberry, due to sugar. He claims this is all to lay the foundations for good gut health and prevent type ii diabetes, which runs in his family. He doesn’t prepare our baby’s solids and I feel like it’s really limiting what I can give him. I know it’s still early days in the BLW journey, but my partner hasn’t given me an indication of when, or if, our baby will ever be allowed to try these things? I’ve told him he needs to perhaps do some more research into his claims, which hasn’t gone down well. What is everyone’s opinion of this and is he correct? (My partner will only allow egg, natural yoghurt, steak, strawberries and avocado).
