The remaining 10–30% of type 1 diabetics have β-cell destruction but no sign of autoimmunity; this is called idiopathic type 1 diabetes and its cause remains unclear. Environmental
Various environmental risks have been studied in an attempt to understand what triggers β-cell autoimmunity. Many aspects of environment and life history are associated with slight increases in type 1 diabetes risk, however the connection between each risk and diabetes often remains unclear. Type 1 diabetes risk is slightly higher for children whose mothers are obese or older than 35, or for children born by caesarean section. Similarly, a childs weight gain in the first year of life, total weight, and BMI are associated with slightly increased type 1 diabetes risk. Some dietary habits have also been associated with type 1 diabetes risk, namely consumption of cows milk and dietary sugar intake. Animal studies and some large human studies have found small associations between type 1 diabetes risk and intake of gluten or dietary fiber; however, other large human studies have found no such association. Many potential environmental triggers have been investigated in large human studies and found to be unassociated with type 1 diabetes risk including duration of breastfeeding, time of introduction of cow milk into the diet, vitamin D consumption, blood levels of active vitamin D, and maternal intake of omega-3 fatty acids.A longstanding hypothesis for an environmental trigger is that some viral infection early in life contributes to type 1 diabetes development.
