Re: --Calcium & Vit D plus other Alkaline Minerals--
ML is right... many acid forming foods today should not be acid forming. These foods were not acid forming in an age when most foods were wild crafted or grown and cultivated in good soils maintained with good stewardship practices. They are acid forming today due to their very poor quality, caused in part by corporate farming practices that have only one thing in mind... profit.
In general, organic food is better quality than conventional food, HOWEVER, organic quality is not what many believe it to be and in fact can be of very poor quality. I would go so far to state that ALL available foods are declining in food value as time goes on, whether that food is organic or conventional for any number of reasons.
"Processed" foods whether organic or not have been found to be equal in nutritional value. Organic processed food may eliminate chemical corporate food production poisons, however the nutritional value is no different... this causes a more acidic forming food as the alkaline minerals are reduced and the balance is lost.
Whole, organic food costs more and is more labor intensive to prepare than processed foods... but, if of high quality, whole organic foods retain the nutritional value that is stripped out of the food and sold to you again as nutritional supplements in the health food store, right alongside the very food that sourced the supplements...
