Is it true that belting causes vocal nodes?

No, it is not true that belting causes vocal nodes. Vocal nodes are caused when the vocal cords do not come together. The cords or vocal folds must adduct cleanly and stay pressed together for closure. The firmer and more complete the approximation the better.

Fiber optic studies of the vocal cords show that in the properly trained Belt singer, the vocal cords are held together even tighter and for longer periods of time than in the classical voice. The nature of the Belt technique itself favors proper approximation, even more so than in the classical voice.

When the vocal cords (folds) are thrown together without vibrating air passing through them, a rather hard attack is heard and can be felt. This attack is called a "glottal." It can happen to any kind of singer, classical or belt. Proper closure can be taught as a correct principle of support and production. It can be taught to a belter or a classical singer. Belting does not cause glottals-faulty technique does!

Vocal nodes are a serious concern to all kinds of singers because of the damage they cause to the vocal instrument. However, nodes are a result of improper singing technique, speaking and yelling improperly, clearing one's throat continually, or numerous other problems but NOT correct Belt singing.
