Purpura nephritis is a relatively serious type of nephritis, and once it occurs, patients will suffer for life. Although nephritis is not common, with the continuous improvement of people’s living standards, the incidence of this disease is also increasing, and many healthy individuals have contracted purpura nephritis. After the onset, dietary and lifestyle adjustments are necessary. So, what can purpura nephritis patients eat? What are the taboos?

1. Increase the intake of light and diuretic foods. Foods with diuretic and edema-reducing effects include crucian carp, crucian carp, goat’s milk, watermelon, winter melon, mung beans, and red beans. Boiling water with watermelon rind has a good diuretic effect.

2. Increase the intake of foods rich in vitamins. Fresh vegetables and fruits are alkaline foods that can provide a variety of vitamins and promote the recovery of kidney function.

3. Avoid high-sodium diets. The relationship between edema in chronic nephritis and blood volume, as well as sodium, is significant, so it is necessary to limit salt intake and provide a low-sodium diet. The daily intake of salt should be controlled below 2-4 grams to prevent the exacerbation of edema and an increase in blood volume, which may lead to accidents.

4. Avoid or eat less high-fat foods. Chronic nephritis patients may have symptoms of hypertension and anemia. Animal fats are detrimental factors for hypertension and anemia because they can exacerbate atherosclerosis and inhibit hematopoietic function, so chronic nephritis patients should not consume excessive amounts of animal fats.

5. Avoid using strong seasonings, as strong seasonings are detrimental to kidney function and should be avoided. Monosodium glutamate should be used sparingly due to its tendency to cause thirst and a desire for drinking, especially when water intake is restricted.

6. Limit the intake of plant proteins, and the amount of protein should be determined according to the condition of kidney function. When patients exhibit oliguria, edema, hypertension, and nitrogen retention, reduce the burden on the kidneys and avoid the accumulation of non-protein nitrogen in the body. In particular, plant proteins contain a large amount of purine, which can exacerbate the intermediate metabolism of the kidneys, so it is not advisable to use legumes and legume products as nutritional supplements.
