Hi,
Simply put, keloid growth is not related to any food factors, although there are the usual unsubstantiated internet claims that sugars, nitrate-rich foods, alcohol, and caffeine may worsen keloids.
The major known risk factors of keloid growth include genetic factors, location of injury (back of neck, upper back, shoulders and front of chest having the greatest risk), tension of wound, infection, and persistent inflammation.
These are the main factors that really need to be considered carefully when deciding on non-emergency and non-critical surgery in a keloid-prone patient.
Hope this helps!
