1, sodium intake: edema should be into a low-salt diet, so as not to aggravate edema, generally no more than 2g of salt per day is appropriate, prohibited pickled products, less use of monosodium glutamate and alkalinity, edema subsides, plasma protein is close to normal, can be restored to ordinary diet. 2, protein intake: nephrotic syndrome, a large amount of plasma protein from the urinary excretion, the human body protein is reduced in protein malnutrition, hypoproteinemia makes plasma colloid osmolality decline, resulting in stubborn edema, body resistance also declined, therefore, in the absence of renal failure, the early, extreme period should be given a high quality protein diet (0.8 ~ 1.0g/kg * d), such as fish and meat. such as fish and meat. This helps to alleviate hypoproteinemia and some of the ensuing comorbidities. When the urine protein turns negative, plasma albumin is normal, then switch to low quality protein diet. Fat intake: patients with nephrotic syndrome often have hyperlipidemia, which can cause arteriosclerosis and glomerular injury, sclerosis, etc. Therefore, we should limit the intake of cholesterol-rich and fat-rich foods, such as animal offal, fatty meat and certain seafood. Supplementation of trace elements: Due to the increased permeability of glomerular basement membrane in patients with nephrotic syndrome, in addition to the loss of a large amount of protein in the urine, there is also a loss of certain trace elements and hormones combined with protein, resulting in the lack of calcium, magnesium, zinc, iron and other elements in the human body, which should be given appropriate supplementation. Generally, you can eat vegetables, fruits, grains, seafood, etc., which are rich in vitamins and trace elements.
