Can people on a kosher diet eat peanut butter?

The answer is: it depends

Explanation:

According to Orthodox Jewish dietary laws, peanut butter is considered parve, which means that it is neither meat nor dairy. However, some kosher consumers choose to avoid peanut butter because it is often processed on the same equipment as non-kosher foods, such as pork or shellfish. Additionally, some kosher consumers may avoid peanut butter because it is a common allergen, and they wish to avoid any potential health risks.
