New research found that fermented foods like sauerkraut and kimchi help fight flu. 

A new study by Korea University, the World Institute of Kimchi, and Daesang Corporation found that laboratory rats injected with the flu virus and fed daily lactic acid bacteria had a 100% survival rate with no side effects. 

The research team has applied for two patents based on the research, and intend to develop and market "functional foods." 

We recommend plenty of fermented vegetable foods in your diet, foods like sauerkraut, kimchi and fermented hot sauce, which are Spartan Diet staples and which you can make at home.
