Owners of Goldens that live/d longer than their average lifespan of 10-12 years old, what food do you feed them

My pup just celebrated his 6th birthday which is already half way of his supposedly lifespan. I know there are plenty of other factors impacting the longevity of their life, but I hope maybe some of you can share your experience/tips in terms of food for a healthy long living Golden! TIA
