Dairy is not really a cheap source of protein. Most vegetable sources are cheaper - pulses and whole grains.
>It is, however, annoying that the price has gone up by about 22% in the last 10 years.
No, it's really not that annoying. Many of the other foods on that list have undergone similar increases and that 22% hasn't even kept up with inflation. This is also despite the fact that the dairy industry is pretty heavily subsidized. I'm far more annoyed that the price hasn't gone up more to reflect the true cost of dairy.
