Healthy Diet
Another way of treating cold sores is to consume a balanced diet. This helps to strengthen the immune system against viruses. It’s advisable to add raw alkalizing foods (fruits and vegetables are very good for the immune system) to your diet. Research has shown that vegetables such as broccoli, cauliflower avoid arginine: cold sores need arginine (amino acid) to persist, so doctors always advise patients to stay away from excess amino acid cabbage. Brussels sprouts and kale are great to improve cold sores. Nuts, chocolate, oats, and some protein have high arginine levels, so they are to be avoided. A healthy diet also helps to prevent outbreaks. Eating a balanced diet and getting regular sleep can help prevent the spreading of cold sores. Sometimes a dietician is needed to maintain consistency.
