We all know about lemon, honey and ginger for fighting colds and boosting immunity. Here are some  delicious alternatives to tempt your taste buds whilst fighting infections.

Brazil Nuts

Just one ounce contains your daily recommended dose of selenium. Selenium boosts your body’s production of cytokines. These small proteins are helpful in clearing viruses. Studies suggest that people low on selenium experience more lung inflammation during colds and flu viruses.


Natural yogurt is full of beneficial bacteria which lives in the gut and blocks the replication of viruses once they enter the body. Choose an organic variety with no added sugars.

Sweet Potatoes

Full of beta carotene Sweet potatoes convert into vitamin A in our bodies; supporting our immune system and helping in the rebuilding of mucus membranes. Sweet potatoes are also a source of virus-fighting vitamins C and D. Sweet potatoes are lovely in soups (add lots of greens for detoxification) or cut into wedges with a little olive oil in the oven.


The amino acid cysteine, released from chicken during cooking, chemically resembles the bronchitis drug acetylcysteine, which may explain the results. The soup's salty broth keeps mucus thin the same way cough medicines do. Added spices, such as garlic and onions, can increase soup's immune-boosting power.


Selenium, plentiful in shellfish such as oysters, lobsters, crabs, and clams, helps white blood cells produce cytokines—proteins that help clear flu viruses out of the body. Salmon, mackerel, and herring are rich in omega-3 fats, which reduce inflammation, increasing airflow and protecting lungs from colds and respiratory infections.


In Traditional Chinese Medicine, Mushrooms – particularly shitake, reishi and maitake are recommended to fight respiratory ailments. Recent western studies show that all types of edible mushrooms can fortify immunity. Lightly fried they make a great breakfast alternative.

Red bell Peppers

High doses of vitamin C are crucial to curing colds and viruses. Bell peppers have a very high vitamin C content and are delicious eaten raw.
