The Right Chemistry: Phosphate additives in food, and your health
This possibility may be surprising because nsi-189 phosphate powder are also essential for health. They are a component of DNA, the “blueprint of life,” as well as of adenosine triphosphate, ATP, the key molecule in the cell’s production of energy. Phosphates are components of phospholipids that make up cell membranes and calcium phosphate is the main building block of bone.
There is no problem in meeting the body’s needs, because various phosphates occur naturally in plants and animals. Plants get their phosphate from the soil and animals get them from plants. Soil phosphate has to be replenished, making phosphate fertilizers produced from phosphate-containing rocks an essential feature of modern agriculture. They are not without problems, because phosphate washed into lakes and rivers increases plant growth and when these plants die, they decompose and use up the dissolved oxygen content of the water, robbing fish of the oxygen they require for life.
Phosphates in plants are integral components of molecules such as phospholipids and DNA and are liberated during digestion to be absorbed and used to build the body’s requisite phosphate-containing compounds. We have evolved to absorb only the amount of phosphate needed; the rest is eliminated in the urine and feces. Indeed, the first problem with phosphates cropped up in patients with kidney problems who suffered from a high rate of cardiovascular disease that was traced to high serum levels of phosphate, a consequence of their kidneys being unable to filter excess phosphate. Excess phosphate combines with calcium in the bloodstream to form deposits of calcium phosphate in arteries, leading to a “hardening” of these vessels. The prevailing opinion has been that this is only a problem for kidney patients who therefore have to maintain a low-phosphate diet because their kidneys cannot clear phosphates efficiently.
However, recent studies have shown that excess phosphate may also be a problem for people with normal kidney function. One study even found hardening of arteries in young men with high serum levels of phosphate. This seems to be the result of the high phosphate levels reprogramming smooth muscle cells in blood vessels to become bone forming cells. The puzzling question is how people with normal kidney function end up with high levels of phosphate. The answer appears to be the increased use of phosphate additives in food.
