How Can Canned Food Products Affect Your Kidneys?

Blood circulation is one of the most important functions in our body because blood is the medium that carries oxygen and all the significant nutrients to the different organs. When blood circulation takes place, a certain pressure is exerted on the arteries of the heart and the blood vessels. However, when this pressure increases, a condition called high blood pressure develops whereby the systolic and the diastolic pressure escalate above the normal levels. High blood pressure not only leads to the damage of the heart, the brain and the eyes, it also leads to the impairment of the kidneys.

To combat a fast-paced life in an urban setting, we adapt certain lifestyle measures which serve some of the core purposes, like satiating our hunger, quickly. One of these measures includes the intake of canned products. With canned foods, cooking becomes faster and easier. But, one of the major downsides of canned foods is that too much of it can lead to the development of high blood pressure.

The link between BPA and canned foods
BPA or Bisphenol A is an industrial chemical that is present in high concentrations in canned foods and beverages. According to researchers, our body contains the reproductive hormone, estrogen in a particular amount. However, BPA mimics the properties of estrogen and tampers with the cells of the heart and our blood vessels that are otherwise sensitive to estrogen, thereby increasing the chances of high blood pressure. Because of that, same reason BPA can also lead to the development of cardiovascular disorders.


BPA is also the primary chemical used to prepare the food containers or the cans. That is why when people drink or eat from these cans, the body accumulates the chemical as well.

According to medical experts, the systolic pressure rises by 5 mm of Hg after consuming two bottles of canned beverages. To detect this effect better, a medical team conducted a study using 60 men and women, among whom some were asked to drink soy milk from canned bottles and the remaining drank the same product from glass bottles. After this, these 60 men and women underwent a urine test. The test results showed that those who drank from canned bottles had a significant amount of BPA in the urine, which concluded the fact that canned foods are not such a healthy option after all.
