Milk is not a necessity of life, plus it's not that healthy. So who cares. The pricier the better.
The milk is a very important food stuff and nutrient, for all age groups; the natural milk of cows and sheep is of a very high value for its content of protein, fat, carbohydrate, vitamins, minerals and so many other essential substances and compounds including also many antibodies against the microbes and the rest of nutrient substances.
َQuran 16: 66, which means:
{
Surely there is a lesson [and indication] for you [about God’s might], included in the cattle:
We give you to drink of that which is in the interior [of the udder] – from between the filth and the blood – pure milk, [uncontaminated with any filth or blood] e, palatable to drinkers.}
...........................................................
e That is because
the fodder which the cattle eat, will lead to the formation of the blood and the milk and the rest will be filth or dung.
So God – be glorified – did not mean with His saying (from between): the place between the dung and the blood; but this is a parable of the might and ability; the Arab say: “From among many hundreds, it was I who succeeded.”
And “From among all people, it was I alone who could see the crescent or the new moon.”
It means: I was capable to succeed so I succeeded and I saw it.
Therefore, (from between the filth and the blood) means:
the food will form the blood and the rest will become dung; but with Our might and ability,
We formed another item which is the milk, for We made another set for milk formation in the udder of the female among the cattle and others, and We gave it to you to drink.
Moreover, (of that which is in the interior [of the udder]) indicates the masculine tense in Arabic grammar; it is about the inside of the udder, not about the inside the belly of the cattle, because the site of the milk is not in the abdomen of the cattle but in their udders.
And for this reason, it is mentioned in masculine tense in the aya.
