22. Canned foods can be harmful.
Canned foods, such as soups, vegetables, and beans, are often purchased because of their low cost and convenience. However, most canned foods contain high amounts of sodium, as salt is added as a preservative to increase its shelf life. Due to the amount of sodium found in canned goods, it’s often recommended that people with kidney disease avoid or limit their consumption. What’s even more worrisome is that, according to a study published in the Journal Kidney International, the lining inside food cans might increase the risk of kidney and cardiovascular disease at the same time.
The study compared the levels of BPA (Bisphenol A), which is used to make the epoxy linings inside the cans, with the protein albumin levels. Too much albumin can indicate kidney problems and cardiovascular disease. The study concluded that a high-level concentration of BPA in the urine is also connected with the albumin. Choosing lower-sodium varieties or those labeled “no salt added” is typically best. Additionally, draining and rinsing canned foods, such as canned beans and tuna, can decrease the sodium content by 33-80%, depending on the product.
