Many studies show that a high-fiber diet is not only beneficial for the digestive system but can also reduce the risk of chronic kidney failure - a silent but very serious progression of the disease.
One of the nutritional factors that is focused on is fiber, a component mainly derived from plants such as green vegetables, fruits, whole grains and beans.
First of all, fiber helps improve digestive function and balance the intestinal microbiome. When fiber is consumed more, it will absorb water, soften stools and increase the amount of food in the intestines, thereby reducing constipation and reducing pressure on the intestinal nervous system.
A healthy digestive system helps reduce the burden on the metabolism of toxins and maintain the filtration function of the kidneys. Soluble fiber also helps reduce bad cholesterol levels and stabilize blood sugar - two main risk factors that damage blood vessels and worsen kidney function over time.
An important point in the link between fiber and kidney failure is that fiber helps reduce systemic inflammation and oxidative stress. Products metabolized by gut bacteria from fiber such as short-chain fatty acids have anti-inflammatory effects, supporting the protection of kidney cells from damage.
In addition, a high-fiber diet often comes with a reduced consumption of animal protein and processed foods. Thereby reducing the burden of nitrogen and acid on the kidneys – especially beneficial for people who are in the early stages of chronic kidney disease.
The role of weight control cannot be ignored. A high-fiber diet helps create a long-lasting feeling of fullness, supports weight control and reduces the risk of obesity – a factor that increases the risk of high blood pressure and diabetes, the two leading causes of kidney failure. Therefore, enhancing fiber not only directly improves kidney function but also indirectly protects kidneys through controlling related risk factors.
How to build a high-fiber diet
A diet rich in fiber, balanced and diverse is not only good for the digestive system but also plays an important role in reducing the risk of kidney failure through many mechanisms: Improving metabolism, reducing inflammation, controlling weight and protecting blood vessels.
Therefore, housewives should build a habit of eating more vegetables, fresh fruits and whole grains - a practical nutrition strategy to protect long-term kidney health for family members.
To have a high-fiber diet, housewives should choose vegetables such as cabbage, broccoli, napa cabbage, bell peppers, cucumbers; apples, pears, red grapes, pineapples, guava, tangerines; egg whites, salmon, fatty fish... In which, prioritize vegetables, choose suitable fruits, control salt intake and have reasonable protein.
