How are onions and garlic to be considered as non vegetarian food?
Once, in Satya Yuga the rishis were performing gomedha and asvamedha sacrifices for the welfare of the whole universe. A cow or a horse would be cut into pieces and placed in the fire. Afterwards the rishis would utter mantras and the same animal would come alive in a beautiful young body. One time the rishi who was about to perform a gomedha sacrifice, his wife was pregnant. She had a very strong desire to eat and she had heard that if, during pregnancy one has a desire to eat and does not fulfill this, then the baby that will be born will always have saliva coming from its mouth. Very strangely, she desired strongly to eat meat, thus she decided to keep one piece of meat of the cow’s body that was offered in sacrifice. She hid it and was making a plan to eat it very soon. At that time the rishi was finishing the sacrifice and uttered all the mantras for the new young cow tocome to life. However when he saw the new cow, he noticed that there was a little part missing from her left side. He went into meditation and realized that his wife had taken away a piece of meat during the sacrifice. Now his wife also understood what happened and quickly threw the meat far away in a field. Due to the effect of the mantras uttered by the rishi there was now life in this piece of meat. Then the bones in that piece of meat became garlic and the meat became onions in that field. Thus these foods are never taken by any Vaishnava devotee because it is not vegetarian. Plus it is in the mode of ignorance.
Don't know which purana it is from.
From practical/scientific standpoint, they are considered non-vegetarian because they have similar effect on body - they incite nervous system & stimulate sexual desires. In fact, garlic is prescribed as medication for men for sexual imbalances.
