Nutrition and Nephrotic Syndrome
Nutritional requirements for a child with nephrotic syndrome
Children with nephrotic syndrome may have trouble regulating their body's water balance. This can cause fluid retention (edema). The diet for a child with nephrotic syndrome may include salt (sodium) and fluid restriction. These restrictions in the diet may help to regulate your child's fluid balance. Any food that is liquid at room temperature counts as a fluid. This includes the following:
Milk, water, juice, soda, and other drinks
Ice cream, sherbet, frozen yogurt
Helpful hints for restricting your child's fluid intake
Your child's healthcare provider will discuss with you how much fluid your child should have on a daily basis, based on his or her medical condition. The following recommendations may help with effectively monitoring and restricting your child's fluid intake. Talk to your child's healthcare provider for more information:
Identify the amount of fluid your child's favorite glass or cup holds, so that you do not have to measure your fluids every time. Try using small glasses. Small amounts of fluid in a big glass look like less than small amounts of fluid in a small glass.
Keep track of how much fluid your child drinks each day. Record amounts on a chart by the refrigerator or another convenient place.
Avoid salty foods, as they increase thirst.
Iced tea and lemonade quench thirst better than soda.
Frozen pieces of fruit (melon, berries, grapes) can help quench thirst.
Chewing gum or hard candy can help to quench thirst.
Have your child rinse his or her mouth with cold water, but not swallow.
Sucking on a lemon wedge can stimulate saliva and moisten the mouth.
Splashing cold water on your child's face and body can help him or her cool off.
Staying out of the sun can help keep your child from becoming thirsty on a hot day.
Helpful fluid conversions
Your child's healthcare provider or dietitian will advise you on how much fluid your child may have each day. This amount is usually given in ounces, cups, or cc.
1 ounce = 30cc
1 cup = 8 ounces = 240cc
1 pint = 2 cups = 16 ounces = 480cc
1 quart = 4 cups = 32 ounces = 960cc
1 tablespoon = 1/2 ounce = 15cc
1 teaspoon = 5cc
Following a low-sodium diet
A low-sodium or salt-restricted diet may be used to help prevent or reduce fluid retention in your child's body. The amount of sodium allowed in your child's diet depends on your child's medical condition. Your child's healthcare provider or dietitian will determine how much sodium your child can have. This is usually expressed in milligrams (mg) per day. Some common sodium restrictions include 2,000, 3,000, or 4,000 mg per day. With most low-sodium diets, high-sodium foods are limited. Salt is not allowed in food preparation or at the table.
What foods are high in sodium?
The following foods are high in sodium. They should be avoided if your child has been prescribed a low-sodium diet:
Canned foods (vegetables, meats, pasta meals)
Processed foods (meats, such as bologna, pepperoni, salami, hot dogs, sausage)
Dried pasta and rice mixes
Soups (canned and dried)
Snack foods (chips, popcorn, pretzels, cheese puffs, salted nuts)

What foods are low in sodium?
Plain breads, cereals, rice, and pasta (not dried pasta or rice mixes)

Drinks such as juices, tea, fruit drink or punch, and soda (sports drinks have sodium so these may need to be limited)

How to reduce your child's salt intake
The following recommendations may help to decrease the amount of salt in your child's diet:
Don't use salt in cooking or at the table.
Cook with herbs and spices or, if permitted by your child's healthcare provider, use salt substitutes.
Seasonings with the word salt in the name are high in sodium. When seasoning foods, use fresh garlic or garlic powder instead of garlic salt. Use onion powder instead of onion salt. And try celery seed rather that celery salt.
Eat home-prepared meals, using fresh ingredients, instead of canned, frozen, or packaged meals. When dining out, ask for dressings and sauces on the side for your child. Ask the chef to hold the salt in food preparation.

Orange juice (1/2 cup)Dry cereal (1/2 cup)Toast (1 slice)Margarine (1 tsp)Jelly (1 Tbsp)Low-fat milk (1 cup)
