Intuitive eating or new age BS?

Is there a way that our bodies know what they need at a particular time?

Part of me has heard 'Oh, I just need something sweet in the afternoon" and answered "No, you just need real food, because you're hungry for nutrients" so many times that it wants to say c'mon, leave the new age BS behind. Another part makes interesting spontaneous choices at the grocery store or the fruit stand.

Consider these occasions.
Last winter I was walking home feeling a bit nauseous. I walked by the fruit stand and saw a pineapple. I hadn't bought one in a year. I ate pineapples all week, then got tired of them. At the time of choice I was convinced I needed it. After eating it, I felt great.
A few days ago I bough salmon and spinach. Just like that. There was nothing else I wanted. There were plenty of options.
Today I bought eggplant and garlic and made a rich and quite smelly salad that tasted great. I hadn't made it in 6 months. I had the conscious conviction that this was the best for me at the moment.

So here comes the question? If part of me believes that the need for "something sweet" in the afternoon means that you are just hungry and if a part of me believes that you cannot 'need" processed foods, then does another part believe that you can intuitively choose what's best for you at the moment.

Is there a way that food may connect us to past experiences. When your brain says "pear", does your memory say " eating a pear with Peter on the bench and feeling happy!". When your brain says "pineapple" does it need the digestive enzymes or your childhood memories of feeling safe and cozy?

Is there a map in our subconscious minds of what foods are good when, and if so, is it possible that we can only read it when we don't abuse our bodies with processed foods, alcohol, sodas, etc?

Does the map change with our beliefs?
