5 Best Foods for Flu & Cold Season

Getting sick during cold and flu season may seem inevitable. However, it’s possible to give your immune system a well-needed boost with a few easy adjustments to your diet. Here’s what you need to know about the link between what you eat and how well your body can fight off diseases.

How Eating The Right Food Helps Your Immune System

Researchers are still learning a lot about the link between nutrition and how it affects the body’s defenses. One thing that’s clear, however, is that eating well has a positive impact on the immune system.

While it’s normal for persons to grab a supplement during cold and flu season, that’s not usually enough. The immune system is a complex structure that includes the skin, respiratory system, digestive system, and an entire tracking network that targets pathogens.

That means the immune system is more likely to benefit from a regular infusion of nutrients than the occasional boost of vitamins and minerals. To get to the bottom of this phenomenon, scientists have identified that maintaining a healthy gut microbiome is key.

This microbiome consists of trillions of microorganisms whose activities directly influence a healthy immune response.

For example, certain microorganisms focus on breaking down the short-chain fatty acids that typically stimulate activity in immune cells.

By maintaining the right diet, you’ll encourage the growth of those beneficial microorganisms in the gut microbiome.

Why This Knowledge Is Important

Regardless of the available evidence, some persons still think that proper nutrition only affects weight loss and illnesses such as diabetes, high blood pressure, and heart disease. African Americans, in particular, need to pay attention to taking care of their immune systems.

According to recent data from the Centers for Disease Prevention and Control (CDC), people of color appear to be more likely to catch the seasonal flu. Additionally, they’re at a higher risk of being hospitalized with the flu or flu-related complications.

If adding foods to your diet sounds overwhelming, try going slowly. Research shows that you’re more likely to stick to these changes if they’re introduced at a comfortable pace.

Of course, tweaking your diet might not do much if you don’t take the necessary precautions to protect yourself during cold and flu season. Remember to get the flu vaccine, avoid persons who aren’t feeling well, and keep your hands clean.
