Sodium and kids: how can schools help kids eat healthy?

Posted in: Blogs, Healthy Eating


School age children need between 1200 – 1500 mg of sodium (salt) per day. The upper limit is 2300 mg per day. (The upper limit is the highest level likely to not cause harm; it is not a recommended level of intake). Too much salt can raise blood pressure and increase the risk of heart disease.


Processed foods often contain a lot of sodium. The chart below shows the sodium content of some typical hot lunch items.

Food Approximate amount of Sodium (mg)
Fast food 4 pc chicken strips and fries 2500
1 – 540 mL can ready to eat hearty soup 1400 – 1700
1 – 85 g package of instant noodles 800 – 2100
1 – 425 g can pasta and beef in tomato sauce 1000 – 1400
1 small personal pepperoni pizza 900 – 1450
Fast food grilled chicken wrap 800 – 1300
Fast food chicken fries 850
Fast food 10 chicken nuggets 750
Fast food regular cheeseburger 600 – 700
1 microwave mac and cheese 580
3 slices (2 oz) of sliced sandwich meat (e.g. ham, chicken or turkey breast) 450-500


The amount of salt found in many of these choices exceeds the recommended amount of sodium for the whole day! How can you support kids to eat healthier? Start by offering less of the highly processed foods. Some healthier options for lunches are:

  • Sandwiches made with roasted meats
  • Whole wheat wraps made with eggs or roasted meats
  • Homemade hamburger soup
  • Pizzas made with whole wheat pitas and vegetables.

You can further decrease sodium in foods offered at lunch with these tips:

  • Check the nutrition info on the restaurant menu items and choose the healthier options
  • Limit how often higher sodium foods are offered
  • Offer smaller portions of high sodium foods
  • Get grilled meats if possible instead of the higher fat and salt processed options
  • Skip the fries, offer raw vegetables or canned fruit as a side
  • Choose whole grains (whole wheat or whole grain pasta, buns or pizza crust) where possible

An occasional less healthy food choice will not have a huge impact on a child’s health. However, frequent consumption due to increased availability of less healthy choices does add up. Schools can role model healthy eating by making the healthy choice the easy choice for kids!
