I've read that walnuts can help regulate blood sugar, is that right?

Among the many studies into the use of walnut oil in the management of diabetes, there is research looking at what the oil can do to help to improve the condition of those suffering from diabetes mellitus type 2, which is increasing globally. It found that walnut oil significantly helped to reduce the dangerously high levels of blood sugar in the patients (1).

However, as with anything else, professional advice should be sought before attempting to treat oneself medically with walnut oil.
