> while lactose and butter fat are at best useless for nutrition and at worst harmful. They carry energy, and thus are useful. They would only become harmful if you would produce so much that our bodies, adopted for scarcity, were presented with an excess amount of it over longer periods. And you wouldn't build a society and industry around that kind of production, right? Right?

They carry energy in forms that can cause problems when they represent a too large fraction of the daily energy intake. Moreover, energy from vegetable products like maize, rice, wheat or high-oleic sunflower oil is many, many times cheaper, while also having much less health risks. So eating dairy for getting energy makes absolutely no sense. Energy as carbohydrates should consist mostly of glucose (preferably as starch, for slower digestion). Half of lactose is galactose, which like fructose cannot be used directly, but it must be converted by the liver, which may be overwhelmed when too much is ingested. There are studies that have concluded that galactose, when eaten in excess or when the liver is worse at converting it, can lead to eye cataract. While this is not certain, based on personal anecdotes I believe that this is true, because all of the people whom I know, and who had been eating a lot of dairy for a long time, eventually have developed eye cataracts in their old age. Energy as fat should consist mostly of oleic acid (the main component of storage fat in humans). While the effect of high daily intakes of saturated fatty acids is still debated, the overwhelming evidence is that they are harmful. From personal experience I believe this to be true. Until about 5 years ago, I had been eating large quantities of dairy products every day. Then I have been diagnosed with incipient atherosclerosis, which scared me. Examining my habits, I could not identify any other cause, except the high consumption of dairy. Based on this assumption, I have completely changed the composition of fat that I am eating daily. Now more than 90% of my daily intake of fats comes from a mixture of oils chosen such as to have adequate proportions of oleic acid, linoleic acid, DHA & EPA and liposoluble vitamins. About one year after this change from dairy to healthy fats, all symptoms of atherosclerosis have disappeared and there were also other very noticeable improvements in my cardiovascular health. So now I am pretty much convinced that the fat from dairy products is harmful, at least in excessive quantities. I do not believe that eating once a week something containing milk, cheese, whipped cream or butter can cause any problems, but eating such food every day, most likely will be bad.
