So in order to become Kṛṣṇa conscious, this is necessary, just like an important segment of the work. We cannot accept anything which is not offered to Kṛṣṇa. Therefore this diet, this sort of diet, as you have tasted in our love feast, that is important. We cannot take outside the scope. So in that sense, diet is important. Besides that, from health point of view also, you require a balanced food—carbohydrate, starch, protein, and fat. That is scientific. So fat we are getting from milk, butter. So if I can get fat from milk and butter, why shall I kill the cow and animal? This is humanity.
