1. Dried fruit
Apricots are a potassium-rich food (especially dried apricots), so avoid including them in the diet of people with kidney disease. Each 165g of raw apricot provides more than 400mg of potassium; and 130g of dried apricot provides more than 1,500mg of potassium.
Date, grapes and dried plums also have high potassium content, which is not suitable for people with kidney disease to use. It is estimated that 174g of dried plums provides 1,270mg of potassium. Only 4 dates provide 668mg of potassium.
2. Canned and instant food
Canned foods such as soup, beans, vegetables... all contain high sodium content, because salt is added to increase the shelf life of food. Therefore, people with kidney disease are recommended to limit or avoid using canned foods. Similarly, ready-to-eat foods such as instant noodles, frozen pizza... also contain a lot of sodium, kidney patients should avoid using them.
3. Processed meat
Processed meat is believed to be related to chronic diseases (including kidney diseases) and is often considered unhealthy food due to containing preservatives. Processed meat is meat that has been salted, dried or canned, such as: bacon, sausage, beef jerky... Processed meat often contains a lot of salt in its ingredients, mainly to enhance flavor and increase storage time. If a diet contains a lot of processed meat, the body may tolerate excess sodium.
Processed meat also has a high protein content. If your doctor asks you to monitor your protein intake, people should limit processed meat consumption.
4. Animal organs
Animal organs (such as kidneys, liver, heart... of livestock/poultry) often contain high levels of purines. Eating this type of food too much can increase uric acid levels in urine, thereby potentially creating kidney stones.
5. Pickled foods
Pickled foods are also considered not good for the kidneys. Usually, a large amount of salt will be used in the pickling process, such as a pickle plant that may contain about 283mg of sodium.
6. Alcohol
Drinking a lot of alcohol can negatively affect kidney function. People with kidney disease need to limit alcohol consumption. Because alcohol can affect the ability to maintain the balance of water and electrolytes in the kidneys. This leads to impaired kidney function, increasing the risk of kidney stone formation. In addition, kidney stone formation can also occur due to dehydration when drinking alcohol.
7. Some types of seafood
Squid, scallops... often contain a lot of purines in their composition. Consuming a lot of purines will increase the level of uric acid in the blood, promoting the formation of kidney stones. Therefore, some types of seafood are also considered foods that are not good for the kidneys. If you have kidney disease, patients need to limit including these seafoods in their diet.
Frozen shrimp, packaged shrimp... often contain more salt to enhance flavor and contain preservatives rich in sodium. For example, tripolyphosphate sodium is often added to help reduce moisture loss upon thawing. A portion of 85g of frozen shrimp without powder can contain up to 800mg of sodium. Fried shrimp and shrimp with powder also have similar salinity.
It is estimated that 85g of canned tuna contains an average of about 247mg of sodium. People with kidney disease also need to be careful when using this type of food.
