number one thing you can do for your teeth is to eliminate all sugars except for lactose.

second thing that helps is avoiding acids, acetic, citric, tartaric, especially tartaric acid, that shit turns into rocks. main source is grapes. malic acid too, from apples, isn't much good either.

basically, a diet based on fresh milk and fresh meat, with no starchy vegetables. basically, leaves are ok, but everything else is a no.

yoghurt is ok but i have to avoid cheese too, i have discovered that i break out in a rash if i eat cheese. the other day i had like 400ml of sweetened yoghurt and by the time i got back from a 5km walk home i had a rash that took a bit over a day to subside. that would have been probably 20g of sucrose, cane sugar.

i'm now of the opinion that most general malaise is caused by sugars, most especially malts, but to a lesser extent fruit sugars and acids. and if you want to totally destroy your nervous system, you should try sucralose, and acesulfame potassium. that gave me chronic double vision and tinnitis. i am pretty sure they also operate through the same mechanism - they feed bacteria, and the metabolites of the bacteria are nerve and endocrine poisons that disrupt your whole body.
