This is impossible for other animals. The human being is meant for self-realization, and for that purpose he is not to eat anything which is not first offered to the Lord. The Lord accepts from His devotee all kinds of food preparations made of vegetables, fruits, leaves and grains. Fruits, leaves and milk in different varieties can be offered to the Lord, and after the Lord accepts the foodstuff, the devotee can partake of the prasāda, by which all suffering in the struggle for existence will be gradually mitigated. This is confirmed in the Bhagavad-gītā (9.26).
(Srimad Bhagavatam-----1:13:47-----purport).

The living beings are created by the creator Brahmā, and just to maintain the created living being progressively towards the path back to Godhead, the system of performing sacrifice is also created by him. The system is that living beings live on the produce of grains and vegetables, and by eating such foodstuff they get vital power of the body in the shape of blood and semen, and from blood and semen one living being is able to create other living beings.
(Srimad Bhagavatam-----1:16:20-----purport).

The mlecchas, however, make plans to install slaughterhouses for killing bulls and cows along with other animals, thinking that they will prosper by increasing the number of factories and live on animal food without caring for performance of sacrifices and production of grains. But they must know that even for the animals they must produce grass andvegetables, otherwise the animals cannot live. And to produce grass for the animals, they require sufficient rains. Therefore they have to depend ultimately on the mercy of the demigods like the sun-god, Indra and Candra, and such demigods must be satisfied by performances of sacrifice.
(Srimad Bhagavatam-----1:16:20-----purport).

The human necessities of life are fully supplied by the Lord in the shape of food grains, milk, fruit, wood, stone, sugar, silk, jewels, cotton, salt, water, vegetables, etc., in sufficient quantity to feed and care for the human race of the world as well as the living beings on each and every planet within the universe. The supply source is complete, and only a little energy by the human being is required to get his necessities into the proper channel.
(Srimad Bhagavatam-----2:2:37-----purport).

Persons who have no discrimination in the matter of foodstuff and who eat all sorts of rubbish are compared to hogs. Hogs are very much attached to eating stools. So stool is a kind of foodstuff for a particular type of animal. And even stones are eatables for a particular type of animal or bird. But the human being is not meant for eating everything and anything; he is meant to eat grains, vegetables, fruits, milk, sugar, etc. Animal food is not meant for the human being. For chewing solid food, the human being has a particular type of teeth meant for cutting fruits and vegetables.
(Srimad Bhagavatam-----2:3:19-----purport).

According to Bhakti-rasāmṛta-sindhu, the science of devotional service, one should not eat more than what he requires to maintain body and soul together. Vegetablediets and milk are sufficient for maintenance of the human body, and therefore one has no need to eat anything more to satisfy the palate. One should also not accumulate money to become puffed up in the material world.
(Srimad Bhagavatam-----2:8:21-----purport).

Sensations of touch are perceived due to the thin layer on the skin, and bone is as good as hard stone. The breathing air of life is produced of sky, air and water, and therefore open air, regular bath and ample space in which to live are favorable for healthy vitality. Fresh produce from the earth like grains and vegetables, as well as fresh water and heat, is good for the upkeep of the gross body.
(Srimad Bhagavatam-----2:10:31-----purport).

The word uru-rasam is also significant here. Hundreds of delicacies can be prepared simply by the combination of grains, vegetables and milk. All such preparations are in the mode of goodness and therefore may be offered to the Personality of Godhead. As stated in Bhagavad-gītā (9.26), the Lord accepts only foodstuffs which are within the range of fruits, flowers, leaves and liquids, provided they are offered in complete devotional service.
(Srimad Bhagavatam-----3:3:28-----purport).

A civilized man is expected to live on foodstuffs comprising fruits, vegetables, grains, sugar and milk. The bull helps in the agricultural process of producing grain, etc., and thus in one sense the bull is the father of humankind, whereas the cow is the mother, for she supplies milk to human society. A civilized man is therefore expected to give all protection to the bulls and cows.
(Srimad Bhagavatam-----3:5:7-----purport).

The jungle animals are also maintained by the Lord with their respective foodstuffs, but they are not advanced in God consciousness. Similarly, human beings are provided with food grains, vegetables, fruits and milk by the grace of the Lord, but it is the duty of human beings to acknowledge the mercy of the Lord. As a matter of gratitude, they should feel obliged to the Lord for their supply of foodstuff, and they must first offer Him food in sacrifice and then partake of the remnants.
(Srimad Bhagavatam-----3:5:49-----purport).
