By "cereal" I have meant cereal plants, i.e. wheat, rye, barley, oats, rice, maize, millet, sorghum and so on, in their raw ingredient forms, i.e. as grains, meal or flour form. Cereals have been the main sources of energy in human food for the last ten thousand years, and among them wheat (because oats is only a minor crop) has also been a non-negligible source of proteins during all this time. I have not referred to "breakfast cereals", which are the most obvious example of garbage food provided by industrial production. (Many decades ago, there has been a time when I was too focused on professional problems and too careless about health and nutrition, and for a long time I have been eating some Nestlé breakfast cereals. After realizing the errors of my ways and blacklisting breakfast cereals, together with other junk food, like fruit juices or fruit yogurt, I was surprised by the quick improvements brought by this decision.)
