Immunity Boosting Foods

Our diet and what we eat is more important than ever today. For most of us, we’re cooking more, exploring new ways of being active and seeking out new hobbies to pass the time at home. For others, there’s a need to save money and keep anxiety at bay.

First, know that in today’s unprecedented time, there is no right or wrong way to feel. Eating a healthy, balanced meal 100% of the time is not feasible for every family, and especially during a time like this, comfort foods are sometimes what we need to feel better. And that’s totally okay!

There’s no magic food that can keep illness at bay, but there are plenty immunity boosting foods available that can also help fight off infection. We’re exploring a few budget-friendly immunity boosting foods below, along with other important tips to keep ourselves and our immune systems healthy.

Which foods can help boost our immunity?

What we eat can play a role in minimizing inflammation and supporting a healthy immune system. It all starts with what you add to your grocery cart.

Best Immunity Boosting Foods

Fresh Produce

The produce department is usually the first destination when you walk into the grocery store. When heading to the produce department, think about what is in season. This is a great time to stock up on in season immunity boosting foods.

When a fruit or veggie is in season, it’s abundant and, not surprisingly, it’s available at a more affordable price. For example, summer is berry season, so that’s why strawberries and other berries are so much more affordable during the summer months.

Keep these longer-lasting fruits and veggies in mind too for a well-stocked kitchen.

Canned food is nutritious!

To ensure that foods are packed at their peak of freshness, most canning facilities are located within a few miles of the point of harvest. Fruit and vegetable canneries often can be seen from the fields where produce is harvested. Making them easy options to add more immunity boosting foods to your diet.

Cheap Immunity Boosting Foods

Don’t forget about frozen produce too.

Frozen can be just as healthy as fresh thanks to American inventor Clarence Frank Birdseye II, who invented the process of flash freezing. Flash freezing of fruits, vegetables, meats, and seafood preserve flavor, quality, and nutrients.

Birdseye discovered the key was freezing the food quickly, locking in foods nutritional value. Flash freezing forms small ice crystals which prevent the cell walls from bursting. Large ice crystals turn the food to mush.

How to boost immunity

Get moving.

Those who exercise regularly have shown to have lower incidences of both acute illness (like an infection) and chronic illness (like diabetes). Exercise contributes to general good health and therefore to a healthier immune system.

Physical activity may contribute by promoting good circulation, which allows the cells and substances of the immune system to move through the body freely and do their job more efficiently.

Looking to move more as a family? In the Making Exercise a Family Affair episode of the Healthy Family Project, Lesley Daniels discusses the importance of exercising as a family.

Lesley shares tips on everything from fitting in exercise in your family’s daily routine, how to fit exercise in no matter the season and how to enjoy exercise as a family.

Easy ways to boost immunity

Get enough sleep.

Research shows that people who are not getting quality sleep or simply enough sleep are more prone to get sick after being exposed to a virus, such as the common cold. During sleep, your immune system releases proteins called cytokines. Certain cytokines increase production when fighting off an infection. Lack of sleep can cause a decrease in the production of these cells making it harder for your body to recover.

Prioritize better sleep hygiene by creating a relaxing nighttime routine. Turn off electronics at least a couple hours before bed.

Best ways to boost immunity

Wash your hands.

May seem like a no brainer, but be more mindful of washing your hands throughout the day beyond after using the restroom or before preparing food. Wash hands every time after playing outside, using a tissue, running errands, etc. Your hands touch many surfaces throughout the day that can easily pick up germs.

Top ways to boost immunity

Manage stress.

Long term stress can elevate cortisol levels, the steroid hormone that regulates a wide range of processes throughout the body, including metabolism and the immune response.

When cortisol levels are constantly elevated, it slows down the immune system to kick into gear to do its job to protect and fight against germs like viruses and bacteria.

Find a stress-reducing technique that works best for you. Try a meditation app like Headspace or Calm. Do a crossword puzzle or color. Find what works best for you.
