Are you looking for snacks that feature foods to strengthen your immune system? If you snack, make snack foods count towards your health by including superfoods for your immune system!

Superfoods for immune system

Why and how to include superfoods for immune system function

A healthy diet that includes a wide variety of immune-boosting nutrients can be part of your strategy for optimal health. In fact, it is best to explore a wide variety of nutrients and antioxidants from foods instead of focusing on a single dietary supplement or nutrient.

Some immune-system strengthening nutrients found in superfoods include protein, vitamin A, vitamin B6, vitamin C, vitamin E, folic acid, selenium, zinc, iron, and copper. Scientists are also exploring how our digestive system defends us from outside invaders. This is where prebiotics and probiotics come into the picture. They help you maintain a healthy gut.

Of course, along with a healthy diet, holistic strategies such as getting enough sleep, staying active, managing stress, and washing hands are essential for a robust immune system.

Ideas for including immune system superfoods at snack time

If you are a snacker, selecting foods that count towards your health is smart. Ask yourself"Do I focus on healthy foods during meals but use snack time to junk out?"

Here are some superfood snack ideas, all under 150 calories, which focus on essential immune system strengtheners (e.g., nutrients, antioxidants, prebiotics, and probiotics) to boost your immune system's power.
