Is it better for your health to drink milk which still contains the permeate?
There are minimal nutrient and no health differences between permeate-free milk and milk where permeate is added.

Permeate refers to the natural lactose, vitamins and minerals component of milk, which is different to the milk protein and fat, collectively known as the 'milk solids'.
Permeate is routinely filtered in a process called ultrafiltration and can be added to milk batches as a way of standardising the nutrient content of fresh milk. Milk’s nutrient content naturally fluctuates between seasons so permeate may be added to ensure a consistent year-round composition.

Some manufacturers will label their milk as 'permeate free' or 'no added permeate'. This means that during processing, permeate is not added to the milk to standardise it. There is no evidence to show which end milk product is better for you.
