I have been in the practice of consuming approx. 2/3 cup of vinegar per day for the past 3 months. It has yielded increases in energy and a feeling of 'cleanliness'(ie. digestive tract). I recently added lemon juice to the concoction that I consume prior to meals hearing that it would stimulate the production of hydrochloric acid and so facilitate digestion. Usually I consume only a few sips equally approx. 3 tbsps. of vinegar/lemon juice diluted in spring water(probably 125 ml of liquid) and this four times per day minimum. I have noticed that with the addition of the lemon juice I have observed(visually and through other senses-tongue, etc.) that my teeth have worn down to some extent becoming more opaque and less 'calcified', if thats the proper term. In short less dense. I assume tooth enamel is a correct index of bone density under normal conditions so I am wondering if either the lemon juice or vinegar(or both) are decreasing bone density. Note: I am drinking this concoction through a straw so as to avoid contact with the teeth. I had done some research into the drinking of vinegar as an ancient practice in the orient and greece and this led me to include it in the diet. Maybe I should diminish the amount consumed, limit/omit the lemon juice, increase calcium/minerals/vitamins that increase bone mass...or something else...or nothing else? Does anyone have any ideas about the influence of exogenous consumption of acetic/citric acid on bone density?
