Onion, cabbage, radish, potato, drumstick, lotus root, etc., are among the vegetables that are to be avoided. Modern day fruits such as Kiwi, etc. are not accepted by elders
Notes:
Swami Desikan has explained clearly about the vegetables that are fit for consumption in Aharaniyamam, along with those that are to be avoided. In short, fruits and vegetables that are not offered to Bhagavan are to be avoided by us.
