Power foods that fight cold sores – Part I

They say:  What you eat is what you are. For cold sore sufferers this expression should be gospel. Your diet has a direct impact on your body and immune system. When your immune system is not in shape… A cold sore outbreak can occur. Here are some foods that you should consider integrating in your daily diet.

Cruciferous veggies

Broccoli, Garden Cress, turnip, Brussels sprout, cauliflower, cabbage, Bok Choy has a high level of Indole-3-Carbinol.  Indole-3-carbinol(I3C) is a phytochemical, a compound found naturally in cruciferous veggies. Clinical studies show that this compound has the potential to interfere with the way the Herpes simplex virus (HSV) reproduces. 2 daily portions of cruciferous veggies are recommended for cold sore sufferers.


Papaya is literally packed with Vitamin C. Vitamin C has a huge role to play in cold sore prevention. Vitamin C has been used since the 1930?s as cold sore treatment. They realized that Vitamin C was effective to fight the herpes virus when taken orally. A papaya a day can help you to prevent cold sores!

Cheddar Cheese

Cheddar cheese is very rich in Lysine. Taken in sufficient dosage, Lysine has been proven to slow down the growth of cold sores. Studies came to the conclusion that Lysine can reduce the frequency and intensity of outbreaks. 50g to 75g of cheese daily will give you 1500mg. This is the recommended dose for cold sores prevention.

Organic Sea vegetables

With their high level of sulfated polysaccharides sea vegetables are recommended for cold sore sufferers. The inhibitory effects of sulfated polysaccharides on the replication of herpes simplex virus (HSV) and other viruses have been studied years ago by the Leuven University in Belgium.

Look for sea vegetables that are sold in tightly sealed packages. Avoid those that have evidence of excessive moisture. Some types of sea vegetables are sold in different forms. For example, nori can be found in sheets, flakes, or powder. Choose the form of sea vegetables that will best meet your culinary needs.
