Diabetes is driven by a high-fat diet—not sugar alone, contrary to popular belief. It is often reversible with a low-fat, plant-based diet, though few physicians emphasize this.
The typical pattern: a patient is diagnosed, given medications to manage blood sugar, and keeps eating the foods that caused the problem. If you have type 1 or type 2 diabetes, work with your doctor to adjust medications safely as your needs change.
Type 1 diabetes is usually not reversible unless caught very early; dairy exposure in childhood may trigger autoimmune attack on insulin-producing cells. Type 1 patients may reduce insulin needs substantially on a whole-food plant-based diet—always with medical supervision, as insulin sensitivity can improve within 48 hours.
