The rule book is actually very clear about this, page 7 (emphasis mine):
NATURAL GOODS – Recover
During your turn, you may discard a natural good to regain one lost *heart*. You may do so as many times as you wish and as long as your turn has not been finished (even if all of your AP have been depleated).
So yes, you can move - collect natural good - move - collect natural good - eat natural good - move - eat natural good - end your turn. In this sequence or any sequence you prefer: move - collect natural good - collect natural good - collect natural good - eat natural good - eat natural good - move - move end your turn... and so on. And please don't take this too serious. As long as you have AP you can do everything. Eating and collecting natural goods can also be done with 0 AP remaining as long as you haven't declared your turn over.
