Short answer: Yes, in normal days maida (refined wheat flour) is generally allowed in Jain diet. It is not a root vegetable, so it doesn’t fall under the common root-vegetable restrictions some Jains observe.

A few cautions:

• Some Jains follow additional rules during austerities or fasts (for example, restrictions on certain grains or processing methods). In those cases, check with your guru or local Jain community.
• Ensure the product is pure and free from any non-vegetarian additives or questionable processing, as practices vary by community.
