Milk-proteins are decomposed by enzymes into normal peptides, opioid peptides and amino acids. And to prevent the decomposition of the peptides, these peptides are relatively indigestible. These opioid peptides cause physical dependence in the young, to make sure it wants to drink lots of mother s milk. Also, it makes the young sleep enough. Unfortunately, adult milk-consumers also absorb those opioid peptides.
Wheat Plants use different tactics to scare off attackers.
Some plants contain poison, others just anaesthetize their attackers, like wheat does with opioid peptides. Because wheat contains opioid peptides, priests in ancient Egypt used wheat to hallucinate, and in bandages, to ease the pain of a wound. All wheat-products, like bread, pasta, pizza, cookies, cake and pastries contain opioid peptides. The roman rulers already new that the people wouldn't rise against them as long as they were entertained and fed bread. Some of these molecules are even 100 times more powerful than a morphine-molecule.
