Some children have medical conditions (for example, nephrogenic diabetes insipidus) that require them to follow a very low sodium diet.
The low sodium diet is prescribed by a physician and is one component of effective treatment for NDI. Along with protein restriction, sodium restriction minimizes the kidney’s workload. Adequate water intake and diuretic therapy are also part of the treatment plan.
Some of the dietary restrictions can make it difficult to get enough vitamins and minerals. If your child is following a restricted diet, his or her intake should be monitored by a registered dietitian (RD), and vitamin and mineral supplements may be recommended.

Low Sodium Diet for Infants, Toddlers, and Children General Guidelines Many people with NDI follow a 300-500 mg sodium per day diet. (Compare this to the 2000 mg sodium per day guideline that is recommended for most Americans.) A diet pattern with 500 mg sodium per day should include foods from all food groups. Select foods low in sodium by following some general guidelines and the Food Guide Pyramid:
- Softened water (water treated in a softener) can contain large amounts of sodium. Don’t use softened water for ice cubes or for food preparation.
- Kosher meats and poultry are soaked in salt water. Look for low sodium Kosher products.
A QUICK “RULE OF THUMB”… Use the values below to make a quick estimate of sodium intake. (These are values for foods that are prepared without salt and/or are reduced or low sodium products.)
Milk/Dairy Products – 80 mg sodium per cup
Breads and Cereals – 80 mg sodium per 1/2 cup
Meat (plain) – 25 mg sodium per ounce
Vegetables – 15 mg sodium per 1/2 cup
Fruits – trace amounts of sodium
At this age, children should begin to explore new tastes and textures… slowly. It is a good idea to introduce one solid food at a time. Commercially prepared foods for this age group are generally low in sodium. Read the food label to make sure the foods your infant is eating are low in sodium. Do not add salt to baby food when making it at home. As your baby is introduced to 2nd and 3rd foods and progresses to table foods, pay close attention to the sodium content of foods. Many 3rd foods (especially meats) have more than 100 mg sodium per serving.
Combination foods (for example, meat and rice dinners) have too much sodium too — sometimes more than 200 mg sodium per serving. Because the sodium content of similar foods varies between brands, food labels are the best source of information about sodium content.
Your infant should be eating a variety of foods and exploring new textures. Gradually decrease the number of strained foods your child is offered and begin to introduce chopped, well-cooked vegetables. Slowly introduce a few table foods. As your child is able to grasp foods and bring them to his/her mouth, offer more finger foods. Foods with less than 35 mg sodium per serving Remember, the amount of sodium can vary between brands — always read the label.

Label Reading Tips… How to Find the Hidden Sodium
How to Read a Food Label
Reading food labels is the only way to be sure of the sodium content of foods. The sodium content must be listed on the package – it is usually on the nutrition information panel. Food manufacturers change ingredients all of the time; make it a habit to READ THE LABEL.
nutrition facts
- The label lists the amount of sodium per serving of food (not per package or container).
- Ingredients are listed in decreasing order by weight – if salt or sodium appears on the ingredient list at all, make sure it is near the end.
What the Label Really Means
If the label says… It means…
- Sodium free… salt free
- Very low sodium… Low sodium
- Reduced sodium… Light in sodium
- Unsalted… No added salt Less than 5 mg sodium per serving
- Less than 35 mg sodium per serving… Less than 140 mg sodium per serving
- At least 25% less sodium than the original product… At least 50% less sodium than the original product
- No salt added during processing (not necessarily sodium-free)… Ingredients that shout HIGH IN SODIUM!

How to Evaluate the Sodium Content of Favorite Recipes
- Examine the ingredients.
- What is the sodium content of packaged ingredients? (Read the labels of the ingredients you will use.)
- What is the sodium content of other ingredients?
- Examine any ingredients used in preparation.
- Total the approximate sodium content for the entire recipe.
- Divide the total sodium content by the number of servings the recipe makes.
- Make sure the serving size listed on the recipe is the same as what will actually be served.
- Does this food fit into your child’s food pattern?
- If he eats this, how much sodium will be “left” for the rest of the day?
Example: Billy Bob’s Grandma’s Best Apple Pie
Sodium content of packaged ingredients:
1 cup brown sugar | 86 mg |
2¼ cups all purpose flour | 7 mg |
1 cup butter | 2000 mg |
1 teaspoon salt | 2325 mg |
1 tsp baking powder | 200 mg |
Butter (1 Tbsp to grease pie plate) | 125 mg |
TOTAL | 4743 mg |
Sodium content of other ingredients:
2 1/2 lbs of Apples | 0 mg |
1 Teaspoon Cinnamon | 0 mg |
1 Teaspoon Lemon Zest | 0 mg |
4 Teaspoons Water | 0 mg |
. | |
. | |
TOTAL | 0 mg |
- Total sodium for this recipe equals: 4743 mg
- Total sodium divided by number of servings:
Although this recipe says it makes 12 servings, we make 10 large servings.
So, we divide 4743 by 10 = 474 mg sodium per serving. - Does the food fit into a low sodium food pattern?
This recipe is too high. Although one serving is less than the 500 mg sodium in Billy Bob’s food pattern, it does not leave him with much sodium for the rest of the day. (It would be impossible to eat enough food for one day and no more than 26 mg sodium!)
How to Adjust the Sodium Content of Favorite Recipes
Identify the “high sodium” ingredients.
Can these ingredients be omitted?
What low sodium ingredients can you use as substitutes?
Do the changes make the recipe acceptable? (Evaluate the modified recipe to make sure.)
Example: Billy Bob’s Grandma’s Best Apple Pie
High sodium ingredients:
Salt–can be omitted
Butter–substitute unsalted butter or vegetable shortening
Baking powder–could omit this or use low sodium baking powder
Evaluate the modified recipe:
Sodium content of packaged ingredients:
1 cup brown sugar | 86 mg |
2¼ cups all purpose flour | 7 mg |
1 cup unsalted butter | 0 mg |
1 tsp reduced sodium baking powder | 3 mg |
1 Tbsp unsalted butter (to grease pie plate) | 0 mg |
TOTAL | 96 mg |
Sodium content of other ingredients:
2 1/2 lbs of Apples | 0 mg |
1 Teaspoon Cinnamon | 0 mg |
1 Teaspoon Lemon Zest | 0 mg |
4 Teaspoons Water | 0 mg |
. | |
TOTAL | 0 mg |
- Total sodium for this modified recipe equals: 96 mg
- Total sodium divided by number of servings:
96 by 10 = 9.6 mg sodium per serving. This item will fit into a low sodium food pattern.
