Many of his students assumed that meant they should exclusively work with supplements to achieve the goal. However, many of those same students failed to recognize that various foods have higher or lower contents of those same calcium groups depending on the specific food and also depending on the quality level of the food.
It is well known that Dr. Reams never tired of reminding his students that they should constantly seek out foods higher in overall mineral composition as denoted by higher Brix values. During prodding at the Advanced Anatomy class held in 1984, Dr. Reams shared some nominal calcium type "prominence" values of particular foods he had discovered in over 50 years of research. This seemed a logical outgrowth of his constantly shared information about particular foods being known for particular minerals such as beets being richer in copper, asparagus richer in arsenic, carrots richer in iodine, etc.
This research trove was later organized by Michael Olszta into a single page chart that is of great use to the student trying to minimize certain calcium type overloads and at the same time maximize certain calcium type deficiencies. For example, food "A" may contain more of a particular calcium type (with lesser quantities of other calcium types), while food "B" may have a different calcium type dominance (with lower quantities of other calcium types following).
The wise student usually soon realizes that there is little economy in continuing to eat too much of particular foods richer in certain calcium types at the same time as they are forced to buy supplements to compensate for the lack of other more needed calcium types.
