Here at That's Fit, we often talk about how a healthy diet is good for you. But what does "good for you" actually mean? According to Diet-Blog, a healthy diet can have a positive impact on your immune system -- important information as we head into cold and flu season.

How does diet affect your ability to prevent or fight off nasty bugs? It gives your body the nutrients it needs to not only run efficiently, but also to fight off invaders before they infect. Since eating these foods won't stop a cold once it starts, you'll need to make these highly nutritional choices part of your daily diet.

For a healthy immune system, eat foods like:

• leafy greens, carrots, and sweet potatoes
• 100% juice
• high-quality protein like lean meats and fish, beans, lentils, or soy
• vitamin E-rich nuts and seeds, like sunflower, almonds, and walnuts
• whole grains, oats, quinoa, and brown rice
  
  

Of course, the choices are endless and Diet-Blog has even more ideas for you. Pair a healthy diet with sleep and exercise, and you can say bye-bye to those bugs and hello to a healthy winter.
