An increase in phosphate intake increases blood pressure in healthy adults
Burgers are fashionable. It is known that the increase in consumption of sandwiches with burgers of white flour increases the risk of diabetes and obesity and the consumption of meat should be rather moderate. The Patty's acute crickets also cause carcinogens. Largely unknown is that Scheiblettenkäse is anything but healthy. A study has shown that sliced cheese contains phosphates that can cause high blood pressure in healthy young people.
Fast food puts a strain on the body
A lot of fats and carbohydrates and few fibers: fast food is a huge burden for our body. According to experts, it takes several hours to get rid of high fat and high calorie foods. However, not only unhealthy fats are problematic, but also some salts, which are often found in such foods. For example, in melted cheese, which is used to make hamburgers, you can usually find many phosphates. Those who take large quantities risk high blood pressure, as researchers have discovered.
Although phosphates are also found in natural foods, today's eating habits mean that we are consuming more and more of these salts.
After all, they are used as additives in numerous industrially produced foods: phosphates support the preservation of many meat-based products, keep the coffee in free-flowing powder and make the spreadable cheese spread.
For example, scientific studies have shown that phosphates can alter the inner walls of vessels, increasing the risk of heart attack and stroke. Furthermore, the risk of osteoporosis is increased by too much phosphate in the body.
Even healthy young adults face health consequences: if they ingest too much phosphate through diet, blood pressure and heart rate increase.
This is demonstrated by a study conducted by the University of Basel, which is nowMagazine of the American Society of Nephrology"Has been published.
Risk also to health
As it is in one communication According to the University of Basel, a low phosphate diet has long been recommended for people with chronic kidney problems because a high level of phosphate, for example, leads to deposits in the blood vessels.
With the increase in phosphate intake through diet, however, the likelihood of developing or even dying of vascular calcification or cardiovascular disease also increases in healthy people.
This is indicated by epidemiological studies that examine the relationship between potential risk factors and specific diseases.
A research group led by Professor Reto Krapf of the University of Basel has now examined this statistical report for the first time in a study of 20 healthy subjects.
Half of the study participants received an additional dose of sodium phosphate in tablets for eleven weeks as part of their normal diet, which increased the phosphate content in the blood above the average, although widespread among the general population .
Subjects in the second group took a drug that binds phosphate and inhibits absorption in the body. Furthermore, they received saline solution to make them equal to the first group in terms of sodium administration.
Increased blood pressure and increased heart rate
After six weeks, doctors looked at how different diets affect various indicators of cardiovascular function, such as blood pressure and heart rate.
A comparison between the two groups showed that an increase in phosphate intake significantly increased systolic and diastolic blood pressure in healthy young adults of 4.1 and 3.2 millimeters of mercury, respectively.
At the same time, the pulse rate has increased by an average of four beats per minute.
As a cause, scientists suspect that the increase in phosphate intake or an increase in serum phosphate level affects the sympathetic nervous system, which affects cardiac activity and blood pressure.
However, the effect was reversible: two months after completing the study, the subjects had returned to normal.
Vitamin D without effect
In a second phase, it was examined how the additional administration of vitamin D has an effect. Although the vitamin increases the absorption of phosphates in the intestine, no impact on cardiovascular levels was observed in either group.
"Our results provide an important explanation for the relationship between dietary phosphate intake and the increase in cardiovascular morbidity and mortality in the general population," said study leader Reto Krapf. "These conclusions are important for public health and should be further studied by larger studies in different population groups." (Sb, ad)
