Re:
Sardines are on my craving list too, and it is pretty intense when it comes. What I believe to be true is that as long as the body has the basic needs, the craving will be for relatively "healthy" food.
I found out that if fighting my cravings that would make the food taste and feel less good than it "should".
One other possibility is that our subconscious mind / soul knows better than the day-conciousness what the body needs, and make sure we get the drift by cravings.
I rarely crave like sweets, when it happens I only need a little to feel fulfilled.
