There is no special arthrogryposis diet that improves the condition itself. A healthy balanced diet can still help quality of life by supporting energy, muscle health, bone health, healing, and keeping weight from adding extra strain on the joints. There is not one specific food everyone with arthrogryposis has to avoid, but it makes sense to limit heavily processed foods, too much sugar, and anything that leads to unwanted weight gain or poor nutrition. If the person has chewing, swallowing, or feeding issues, then food choices may need to be adjusted for that.
