Uncontrolled Levels of Minerals

Spinach has many minerals, so it seems logical to eat it when you want to replenish deficiencies. However, this can have quite the opposite effect.

Oxalates are absorbed by the body and combine with magnesium or calcium, reducing their amount in bones, muscles, and joints. The combinations of oxalates with minerals are permanent and detrimental to health.

Large amounts of minerals combined with vegetables rich in oxalic acid are also not a good idea. Such a condition further increases the absorption of oxalates from the digestive tract. In addition, oxalates can significantly increase the amount of calcium excreted, which can contribute to overstimulation.
