Alan Dickens (Letters, April 12) raised the problem of phosphorus regarding sewage treatment. We sink deeper into it if we contemplate that a particular variety of great apes decided to break ranks and switch from carbs-from-fruit to carbs-from-grain about ten thousand years ago.
Unfortunately grain has eight times as much phosphorus as fruit and the acidity of this globalised diet has been wreaking havoc in that particular great ape ever since. Prior to becoming sewage, the acidity [of carbs-from-grain] damages internal tissue, which stimulates inflammation, which then obstructs blood flow – resulting in almost every disease a great ape can think of.
It really shits me that the global food system continues to fart around feeding poison to billions of brainwashed great apes. The food-health industry has probably shortened more lives than the military-industrial complex.
