Milk contains lots of hormones ie prolactin, oxytocin, progesterone, oestrogen etc. When the hormones are out of balance, it may affect the various functions of the body. Many cows are artificially inseminated and impregnated merely two months after they have given birth. The milk of such a cow contains about thirty times more hormones as compared to a non pregnant cow. Such milk, if consumed, could negatively affect our hormonal systems. From an Ayurvedic perspective, both Diabetes and Thyroid are due to an imbalance in the Kapha Dosha ( Earth and Water Elements ). Bad quality milk will lead to the formation of bad quality Kapha which may lead to Kapha related disorders such as Diabetes and Thyroid issues.
