Yup, pregnancy/childbirth/rearing is particularly rife with these. Western sources suggest that eating sushi while pregnant is little short of stabbing yourself in the abdomen with a sharp knife, Japanese sources explicitly recommend sushi as a light and healthy meal. In the US giving any form of peanuts to babies is attempted murder, in Israel peanut puffs (Bamba) are among the first foods offered.
Many of these are due to cultural contexts. For example, I would trust sushi from 7-11 in Japan over most grocery store sushi in the US.
