In Type 1 Diabetes, Fat May Lower Severity of Heart Disease
According to the Pittsburgh Epidemiology of Diabetes Complications Study, a sixteen-year examination of 225 type 1 patients, fat puts you at greater risk of heart disease; once you do get heart disease, however, it's less severe.
When the researchers measured calcium build-up in the coronary arteries that feed the heart (which reflects severity of heart disease), they found that as body weight and fat increased, the risk of heart disease increased along with it. However, as the weight of the patients increased even more, the severity of the heart disease dropped. The effect was even more pronounced in women.
The researchers speculated that the association of fat with less severe heart disease might reflect better control with insulin, which is sometimes correlated with weight gain. They pointed out, however, that weight gain is probably not a good idea and noted that their findings emphasize the complexity of the relationship between diabetes and heart disease.
