What You Should Eat For Stronger Immune System
The right foods can prevent you from getting sick and help you recover quicker if you do fall ill. Here’s how to build a strong immune system and help your body fight off the bad guys.
You got sneezed on in the subway. Coughed on in the coffee shop. Your colleagues keep coming to work when they should be calling in sick. And your kids are bringing home illnesses you never even heard of. How the heck are you supposed to stay healthy?
It might seem like seasonal illness is out of your control. And, yeah, sometimes, sick happens. But you have more power than you think.
Your immune system is an incredible thing. The bacteria in your gut is actually a powerful army willing to fight on your behalf, but only if you feed them properly. And if you do get sick, certain foods can help you recover quicker. What you eat today can determine whether or not you get sick tomorrow.
Here’s how to build a strong immune system and help your body fight off the bad guys.
The immune system is your best line of defense.
OK, gang, it’s time to layer on the armor and bolster our defenses. (And I’m not just talking about scarves and winter coats, though those are probably good to have around too.) To stay healthy, energetic and sick-day-free, we have to strengthen our immune systems.
Here’s how the immune system works: Our body’s battle for immunity begins in the mouth. Bet you didn’t know that your saliva contains powerful antimicrobials like lysozyme, alpha-amylase and lactoferrin.
Any germs that sneak past those will confront our stomach’s hydrochloric acid.
Then, should they survive, they’ll go up against the proteins and chemical compounds in our digestive system that break down bad bacteria.
Finally, our own personal good bacterial population goes to work. They prevent bad bacteria from entering our bloodstream or taking root in our small intestine and colon. Those good bacteria are called probiotics. Think of them as an army against illness.
Feed your bacteria army.
The GI tract comprises over 70 percent of the immune system. That’s home to our good gut bacteria, which fight off a whole lot of yucky stuff.
If you want those bacteria to work for you, you’ve got to feed ’em. They love to chow down on nutrient-dense, fiber-rich whole foods. But processed foods, fats and sugars? Not so much. That’s why a balanced whole-foods diet is your best insurance against all kinds of viruses and infections.
In other words, if your diet is lousy, you’ll get sick more often and stay sick for longer. Eating poorly while you’re sick will only make you sicker. Good nutrition, on the other hand, enables your body to deliver a swift roundhouse kick straight to those germy invaders.
Prebiotics and probiotics.
Want a ready-to-roll squadron of healthy bacteria? Here’s how to keep the soldiers well fed.
Prebiotics (aka bacteria food) help nourish our good microbial friends. Essentially, prebiotics are a form of semi-digestible fiber. You should get at least two to three servings of prebiotic-rich foods each day (more if you’re unhealthy and need extra support from your gut flora).
