Is milk good or bad for health?

Almost all plants have evolved to resist being eaten by animals. Up to 25% of the content of many plants is there not because it helps the plant to grow or propagate but to stop animals, mainly insects but also other animals, from eating the plant. To put this more bluntly, the purpose of up to 25% of all vegetable matter, is to kill you!
Of course, animals have evolved ways to detoxify or excrete the toxins that plants contain, by having livers for example. Many insects specialize in eating one or a small number of plants that their bodies can deal with, other animals, such as humans, can deal with a wider range of vegetable matter, but many plants are still extremely toxic to humans. Animals have even evolved to be unable to synthesize certain essential compounds because they can obtain them from plants.
The point that I am making is that there is nothing inherently natural, safe, or good about eating plants. Roots and leaves all contain toxins intended to kill us but over an evolutionary timespan, we have developed ways to beat some plant defenses and eat them. The only exception to this argument is fruit that is dispersed by animals. In this case, it may be to the benefit of both the plant and the animal that the fruit gets eaten.
Animals also have defenses against being eaten but these are generally, camouflage, speed or weaponry rather than toxins.
Milk, on the other hand, has evolved to be a complete food for the young of the species. Cow’s milk is intended to be a complete food for calves. There has never been any evolutionary pressure for animals to add toxins to their milk. The only animals to seriously consume milk from other species have been humans, who have generally looked after their milk providers. There has, on the other hand, been strong evolutionary pressure not to allow toxins or pathogens to be present in milk.
Most adult mammals cannot digest lactose, the sugar found in milk, but most adult humans can. That tells me that adult humans have consumed milk from other animals for long enough to have evolved the ability for most adults to digest lactose. In other words, we have been consuming milk from dairy animals for a long time. Milk, on the face of it, should, therefore, be one of the safest and nutritious foods that we can consume. Of course, certain farming techniques, such as the excessive use of antibiotics do make milkless good than it otherwise would be, but then pasteurization makes it safer. Also, the general rule that excessive consumption of anything is bad for you still hold.
