Overstimulation of IGF-1-signaling pathways in the brain due to milk consumption could thus accelerate the onset of neurodegenerative disease. IGF-1 passes the blood-brain barrier and reaches the neurons in the brain.

We report the unusual occurrence of eight cases of vitamin D intoxication that appear to have been caused by excessive vitamin D fortification of dairy milk... All eight patients drank milk produced by a local dairy in amounts ranging from 1/2 to 3 cups (118 to 710 ml) daily...
Analysis of the dairy's vitamin D—fortified milk revealed concentrations of vitamin D3 (cholecalciferol) that ranged from undetectable to as high as 232,565 IU per quart (245,840 IU per liter). An analysis of the concentrate that was used to fortify the milk, labeled as containing vitamin D2 (ergocalciferol), revealed that it contained vitamin D3.

Baby rats need rat milk, baby cats need cat milk, baby dogs need dog milk, baby humans need human milk, baby cows need cow milk, baby chimps need chimp milk.. Would anyone believe it if someone claimed adult giraffes need elephant milk? or adult horses need squirrel milk? or adult possums need goat milk? or adult humans need cow milk? oh, wait, no, that last one makes total sense.. NOT

It’s hard to imagine calling the dairy industry anything but “inhumane” when you consider that on dairy farms, cows are artificially inseminated and forced to give birth, only to have their beloved babies torn away from them so the milk that nature intended for them can instead be consumed by humans. Both mother cows and their calves are emotionally traumatised when forcibly separated from one another. The mother cows bellow in desperation, and their calves bawl in distress. They cry out for each other for days – in vain.

The male calves – often referred to as “by-products” – are either shot at birth or destined to become veal. The female calves, like their mothers, face a lifetime of repeated forcible impregnation and anguish over their stolen babies. Their bodies are strained to the limit in order to squeeze out every last drop of milk. Today, British cows typically produce 10 times more milk than they would naturally in order to feed their calves.

If we keep the calves away from their mothers there is a real risk that dairy production will go out of business in markets where animal welfare is a priority for the consumers.

Organic production has a particular challenge since the ideology of organic production and the expectations from consumers include that the food is produced in a natural way and it is very difficult to argue that it is natural for a new-born mammal to be separated from its mother at birth.
