Not all of it was correct. My parents' generation "learned" to avoid eating fats to not become overweight. My grandmother knew that you shouldn't eat fresh bread before it cooled down (unhealthy or so). We researched the latter recently and found out, that this idea was spread after the war so that the children would not eat too much of the freshly baken bread, because it tasted better. No health implications at all.
