True. Fortunately, I do not have milk digestion problems, so I can use whey protein concentrate, from which (by mixing with a vegetable oil) I make something that has the aspect and taste of melted cheese, which I use instead of real cheese. While whey protein concentrate has a little lactose, it has much less lactose than almost all other dairy products. Where I live, in Europe, whey protein concentrate is $0.575 per 25 g of pure protein, including taxes (i.e. VAT) and shipping, so it is a little cheaper than the cheapest protein source on this list. While this list includes enough items with a reasonable price, any of those with a price over $1 per 25 g of pure protein is likely to be an attempt to exploit naive buyers of fitness-related products, by including excessive profit margins.
