Nutrition for Children with 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 cubes
Ice cream, sherbet, frozen yogurt
Popsicles
Gelatin
Soup
Pudding

Helpful hints for restricting your child's fluid intake

Your child's doctor will discuss with you how much fluid your child should have on a daily basis based on your child's medical condition. The following recommendations may help with effectively monitoring and restricting your child's fluid intake. Talk to your child's doctor for more information.

Identify the amount of fluid your child's favorite glass or cup holds so that you do not have to measure 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 their mouth with cold water, but not swallow it.
Sucking on a lemon wedge can stimulate saliva and moisten the mouth.
Splashing cold water on your child's face and body can help them 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 doctor or dietitian will advise you on how much fluid your child may have each day. This amount is usually given in ounces (oz), cups, or cubic centimeters (cc).

1 oz = 30 cc

1 cup = 8 oz = 240 cc

1 pint = 2 cups = 16 oz = 480 cc

1 quart = 4 cups = 32 oz = 960 cc

1 tablespoon = 1/2 oz = 15 cc

1 teaspoon = 5 cc

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 doctor 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 1,500 to 2,000 mg per day. Sodium intake for your child will often be based on their weight. 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. Your child should not eat them if they have been prescribed a low-sodium diet:

Most canned foods (vegetables, meats, pasta meals)
Processed foods (meats, such as bologna, pepperoni, salami, hot dogs, and sausage)
Cheese
Dried pasta and rice mixes
Most soups (canned and dried)
Snack foods (chips, popcorn, pretzels, cheese puffs, salted nuts)
Dips, sauces, and salad dressings

You can often find low-sodium versions of different foods to use in place of the higher-sodium varieties.

What foods are low in sodium?

Plain breads, cereals, rice, and pasta (not dried pasta or rice mixes)
Vegetables and fruits (fresh or frozen)
Meats (fresh cuts, not processed meats)
Milk and yogurt (these tend to be moderate in sodium)
Drinks such as juices, tea, fruit drink or punch, and some soda (sports drinks have sodium so these may need to be limited)

The following are considered low-sodium seasonings and don't need to be restricted:

Allspice
Bay leaf
Basil

Chives
Cinnamon
Cloves
Curry powder

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 doctor, 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.
