Is the husband obligated to feed his wife from the same food he eats? And does she have the right to request food that she desires or that follows a specific diet? And is he obligated to provide her with sweets and similar items if she has no money and he is well-off?

Maintenance is obligatory for the wife upon her husband, in accordance with what is customary, taking into account the financial status of both spouses, whether affluent or in hardship. If both are affluent, then the maintenance is for the affluent. If both are in hardship, then the maintenance is for those in hardship. If one is affluent and the other is in hardship, then the maintenance is for those of moderate means. This includes food, drink, clothing, housing, and what is appropriate for their situation, such as sweets and other items. He is not obligated to accede to every request she makes, but rather he is obligated to give her what is customarily due to someone like her. If the husband eats food that is superior to hers, there is no sin upon him, even if it contradicts chivalry. He is to provide her with sweets and fruits as is customary and considered a regular part of the diet.
