After 40 years old: What should you avoid to prevent liver and kidney deterioration with age?

After the age of 40, the body gradually undergoes many physiological changes, in which liver and kidney function tend to decline. To prolong life, people need to pay attention to daily habits to protect the liver and kidneys.

To keep liver and kidney function stable over time, people over 40 years old need to limit the following:

Food with lots of oil and additives

Eating a lot of fatty foods, such as fried foods, fast foods, and processed meats, causes the liver to work too hard, causing inflammation and fatty liver.

Consuming too many additives such as preservatives, colorants, sweeteners, and flavorings will force the liver to work too hard, easily leading to damage. Some typical harmful effects of additives on the liver are increased risk of hepatitis, fatty liver degeneration, and toxicity to liver cells.

People over 40 years old should not eat too much red meat, especially when the meat is fried.

Drinking a lot of alcohol and sugar can easily cause hepatitis.

The liver is the main organ responsible for metabolizing alcohol. Excessive alcohol consumption leads to hepatitis, fatty liver, cirrhosis, and even liver cancer. Especially when entering middle age, the liver processes ethanol less well, so it is more susceptible to damage. Experts recommend drinking in moderation or, best of all, stopping altogether, according to the health website Healthline (USA).

Meanwhile, added sugars, especially soda, candy and pastries, easily convert to fat that accumulates in the liver, causing non-alcoholic steatohepatitis.

Too much salt and protein

Eating salty foods increases blood pressure, making the kidneys work harder, and can easily lead to chronic kidney disease. Many people think they don't eat enough salt. However, this isn't always true.

Processed foods containing hidden salt are the main cause of high salt intake. These foods include instant noodles, sausages, Chinese sausages, industrial ham, canned fish, fish sauce, pickles, soy sauce, fish sauce or salty snacks.

Meanwhile, a diet rich in red meat causes the body to absorb large amounts of protein. After digestion, protein is broken down into amino acids, which are then further metabolized in the liver and tissues. This metabolism produces nitrogen compounds, mainly ammonia.

The liver then converts ammonia into urea, which is then excreted by the kidneys. Therefore, eating too much protein can be harmful to both the kidneys and the liver.

Avoid overuse of painkillers

Painkillers are essential for controlling muscle pain, joint pain, headaches, toothaches, inflammation and fever. However, if taken regularly for a long time, it can reduce blood flow to the kidneys, causing kidney damage. Older people, especially those over 40, should consult a doctor and avoid taking painkillers for a long time, according to Healthline .
