Flu season is rough. The best way to avoid getting sick is by supporting your immune system throughout the year. This can be done naturally, at home with diet and supplements. I've already done a couple of posts of how to survive flu season: Preparing for the Flu Season and Surviving the Flu Season. Today I'd like to focus on foods that support the immune system.
We all know that when you start to feel under the weather, you take high doses of vitamin C to kick-start your immune system. Foods such as grapefruits, oranges, lemons, limes, tangerines, clementines, red peppers, papaya, broccoli, and spinach are all high in vitamin C.
I did a post dedicated to vitamin D and all its benefits. You can check it out here: Vitamin D. Getting out in the sun can be a little more difficult in the winter when it's too cold to go outside. There are plenty of wonderful foods that contain this essential vitamin, such as whole milk yogurt, fish, kale, olive oil, and sunflower seeds (to name only a few).
This vitamin is an essential antioxidant and free-radical fighter. Foods such as sunflower seeds, broccoli, almonds, and avocados are high in vitamin E.
