Trace minerals and elements have not gotten the attention they deserve for our pets’ health.
One of the reasons this may be problematic is that many ill dogs have low levels of trace minerals. To make matters worse, testing can be difficult as these nutrients are not stored in the blood, making blood testing not very accurate.
The problem is that the soil that crops are grown in, which are used for food, is gradually becoming depleted of minerals due to repeat farming of the same plots of land over time. This is because it is uncommon for farmers to test the soil frequently enough to replace all of the missing nutrients. Sometimes excessive fertilization of some nutrients leads to an imbalance and crowds out absorption of other needed nutrients for the plant.
Another factor is that the source of many mineral like magnesium is from decaying organic material on the surface of the soil, which is not common in agriculture today. Finally, the plants themselves are now designed to be high yield, and tend to need larger amounts of these minerals and nutrients in the soil.
Here is a chart showing how the nutritional value of some foods has dropped over time:
|Table 2. Mineral Content of Selected Produce 1963 vs. 1999 – (mg/100g sample)|
|Apples, raw, with skin||7||7||8||5||110||115||84.8||83.9|
|Beans, snap, green, raw||56||37||32||25||243||209||90.1||90.2|
|Lettuce, iceberg, raw||20||19||11||9||175||158||95.5||95.8|
|Peas, green, raw||26||25||35||33||316||244||78.0||78.8|
It is true that pet foods are supplemented with necessary nutrients to help insure they get what they need. The problem however is that animals who are ill, in many cases including cancer require further support to due imbalances and deficiencies.
The take home message here is that it is important for a dog with cancer to take a multivitamin, as stated in the Guide. Apocaps contains a boost of both magnesium and zinc. Everpup is a good supplement containing an large array of beneficial nutrients as dogs age.
