Back to school time means your kids will be going off to a day of classes with their backpacks and lunch boxes in tow. Now is a great time to instill young minds not only with math and science but also with healthy eating habits – ones that will be beneficial for them as they grow up into adults.

Food is fuel for the brain and for the body. When at school, a healthy lunch and proper nourishment provide a better learning experience and can help with performance in school. In general, kids focus better when they are well-fed, so a healthy lunch is a great way to keep the brain stimulated at school.

Here are a few tips for packing a healthy lunch for the kids:

Sandwiches Made Smarter

Changing up the sandwich is a great way to incorporate healthy choices in an exciting way. Using 100% whole-wheat grains provide extra fiber, which is great for the digestive system and cholesterol and blood pressure levels. Swapping the whole-wheat bread for 100% whole-wheat pita pockets or 100% whole-wheat wraps can add variety to lunches. It is important to look for bread that does not have any hydrogenated oils and that are low in saturated fat. All of this information can be found on the ingredient label. Roll-ups are a great way to have a bread-less lunch. Putting your favorite veggies and deli meats into lettuce-wrapped roll-ups will make it fun for the kids.

For different protein options, try leftover grilled chicken or turkey. Instead of mayonnaise and cheese, substitute avocado, mustard, and/or hummus. Do not forget to add lettuce and tomato for filler, as they make the sandwich larger and provides your kids with extra veggies. Switching the lettuce and tomato for shredded carrots, cucumbers, or zucchini is a good way to change things up, too.

Embrace the Leftovers

Using leftovers for lunch the next day is a great way to add variety to lunches! Plus, we all know meals taste better after a day or two in the fridge! Leftover pasta, preferably whole wheat, with some tomato sauce, or soups, or even chili (turkey or chicken chili) kept in a thermos is a great warm alternative to the daily sandwich. Leftover meat can also be made into kabobs with some extra veggies for a colorful lunch.

It’s Fun to Dunk

Dunking is always enjoyable for the kids and provides a fun way to eat fruits and veggies. Some healthy dunking combinations include:

• Apple or pear slices to dip with low-fat plain yogurt or peanut butter
• Carrot, celery, or pepper sticks with hummus or salsa
• Whole-grain or whole wheat crackers with soups and low-fat dips

Let the Kids Choose

Get the kids involved by letting them choose what to eat for lunch. If the kids are a part of the preparation process, they are more inclined to eat what they made. The night before, have them pick out the bread and fillings to add to the sandwich. In addition, have them choose what kind of fruit or veggie they want to dip and have them help assemble their lunch.

Lastly, make the trip to the grocery store a fun learning experience for the kids. Have them check out the different fruits and vegetables and get them intrigued by the whole shopping process. Eating habits are important, especially at an early age, so there is no better time to start.
