eggs and milks have different disadvantages
i will just throw into the mix that tubers, nuts and drupes have things in them that have certain benefits, notably especially potassium, zinc and magnesium, milks also have a lot of potassium, egg whites can be problematic, i know at least for sure that they cause anemia in felines so probably there is some dangers for us in albumin binding up stuff in our GI tract and blood also, but at the same time there is some great stuff in yolk but at the same time, those hard cholesterols can play havoc with the gallbladder as well!
for sure, boron, potassium and magnesium are three minerals you should investigate because all three can have issues both with mainstream food supplies and with keto/carnivore diets
various other factors play into why these are important, for example, barium additives and pollution from especially aircraft fuel additives can deplete and interfere with potassium, radioactive isotopes like Cesium 137 mess with your potassium also, most processed starchy foods will be low in Boron which leads to elimination of magnesium and potassium
and not to forget, bromine and fluorine cause all kinds of problems in the endocrine system and the main cure is iodine, and the best form is Lugol's iodine and it's important to take it, as much as possible, on an empty stomach without any ascorbic acid or alkali present so that the elemental form gets into the blood as well as the hydriodic acid form
the modern food system and industrial contaminants and building materials are so messed up, there is a whole matrix of problems being caused that are really hard to figure out and some of us poor bastards have had to suffer with for decades
