Why is it that we sometimes crave certain foods? Can it be that your body is sending you a message?

The theory is that people will have a craving for certain things
that will provide a nutrient that is lacking.

In our culture I don’t think there is a metabolic reason for food
cravings. You know if you are used to consuming sugary sweets
and that is all you eat, your metabolism adapts and your body guides you to the foods you are used to consuming.

An example of that would be someone who has gone on a
vegetarian diet and eliminated meat from their diet temporarily.
Then they start to reintroduce meat and their stomach is upset.
Their stomach is not used to digesting that kind of food. They
have adapted to digesting just non-meat items. There are food
digestive adaptations to the kinds of food that you eat. One
would have to believe that those are the kinds of foods that you
get used to.
