it could mean consuming other foods along with sweet foods in order to reduce the glycemic index and thereby, slow or blunt the release of dopamine.

The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

It can be advantageous to ingest sweet foods, either alone or in combination with foods that reduce glycemic index or reduce glycemic load.
if we zoom out and take our perspective on all of this discussion about the glycemic index through the lens of the nervous system and we remind ourselves that neurons prefer glucose for energy and that all sweet things or things that we perceive as sweet, but also sweet things that are ingested and registered by those neuropod cells in our gut trigger the release of dopamine and trigger these neural circuits to make us want to eat more of these foods. What we start to realize is that a sharp rise in blood glucose or a very high degree of elevation in blood glucose is going to be a much more potent signal than will a more moderate rise in blood glucose or a slower rise in blood glucose. And so for those of you that are trying to reduce sugar intake and you want to do that through an understanding of how these neural circuits work and you want to shortcircuit some of the dopamine release that's caused by ingesting sugary foods, it can be advantageous to ingest sweet foods in combination with foods that reduce glycemic index or reduce glycemic load.
So, if you really wanted to adjust your sugar cravings and you really still want to inest some sugary foods, you probably would be better off combining fiber with that sugary or sweet food.
