Is there any suggestion or inputs in diet for my father who will be going through his Full mouth dental implant

He is 55 years old. He will be getting his teeth removed first and for the next two months would be w his denture and then finally the teeth will be placed on his implants.

Is there any suggestion for what kind of diet should I look forward to?

I have thought to make him drink brewed clove and cinnamon water twice a day.

He drinks 1tsp homemade sanjeevni powder water every morning. He also drinks this concussion of turmeric and ginger pulp water every day.

Is there anything else that i can do? Would love to get some insights
