People with kidney disease are able to eat tomatoes. When it comes to kidney disease, it usually refers to nephrotic syndrome, and the food that needs to be avoided in this disease is mainly too salty food and high protein food. Because this disease edema is more obvious, so if you eat too salty will lead to edema aggravation, so for salt, salty food need to limit. The other is high protein food, because a big characteristic of this disease is to lose a lot of protein through the kidneys, if you eat too much protein-rich food, the protein lost from the kidneys will also increase, which will also lead to the aggravation of this disease. And protein-rich foods are mainly dairy, meat, soy products and so on. Tomatoes contain mainly fiber and some water, so it is OK for patients with nephrotic syndrome to eat. However, if the patient’s edema is more obvious, the food such as tomatoes should be appropriately limited, because eating too many tomatoes is equivalent to consuming too much water, which may lead to further aggravation of edema.
