Without disturbing the ecstasy of His mother's affection, Kṛṣṇa opened His mouth and displayed His own natural opulences. When a person is given varieties of food, there may be a hundred and one varieties, but if one likes ordinary śāka, spinach, he prefers to eat that. Similarly, although Kṛṣṇa was full of opulences, now, by the order of Mother Yaśodā, He opened wide His mouth like a human child and did not neglect the transcendental humor of maternal affection.

Cāturmāsya should be observed by all sections of the population. It does not matter whether one is a gṛhastha or a sannyāsī. The observance is obligatory for all āśramas. The real purpose behind the vow taken during these four months is to minimize the quantity of sense gratification. This is not very difficult. In the month of Śrāvaṇa one should not eat spinach, in the month of Bhādra one should not eat yogurt, and in the month of Āśvina one should not drink milk. One should not eat fish or other nonvegetarian food during the month of Kārttika. A nonvegetarian diet means fish and meat. Similarly, masūra dhal and urad dhal are also considered nonvegetarian. These two dhals contain a great amount of protein, and food rich in protein is considered nonvegetarian. On the whole, during the four-month period of Cāturmāsya one should practice giving up all food intended for sense enjoyment.
(SRI CAITANYA CARITAMRTA-----2:4:169-----PURPORT).

There are six kinds of rasas (tastes), and if one is agitated by any one of them, he becomes controlled by the urges of the tongue. Some persons are attracted to the eating of meat, fish, crabs, eggs and other things produced by semina and blood and eaten in the form of dead bodies. Others are attracted by eating vegetables, creepers,spinach or milk products, but all for the satisfaction of the tongue's demands. Such eating for sense gratification—including the use of extra quantities of spices like chili and tamarind—is to be given up by Kṛṣṇa conscious persons. The use of pan, haritakī, betel nuts, various spices used in pan-making, tobacco, LSD, marijuana, opium, liquor, coffee and tea is indulged in to fulfill illicit demands. If we can practice accepting only remnants of food offered to Kṛṣṇa, it is possible to get free from māyā's victimization. Vegetables, grains, fruits, milk products and water are proper foods to offer to the Lord, as Lord Kṛṣṇa Himself prescribes.
