Yes, oats in their natural form without any additions like sugar or flavoring are considered kosher under Jewish dietary laws. In kosher dietary guidelines, oats are considered pareve, which means it is neither meat nor dairy. As long as it is prepared in accordance with kosher rules and does not come into contact with non-kosher ingredients or utensils, oats can be consumed by individuals observing kosher dietary laws. However, for processed oats such as oatmeal, it is important to look for a product that has a kosher certification on the packaging because processing methods or additives may not be kosher compliant.
