Agreed with Patch, since I am low carbing and eating tons of vegetables and berries I havent had the remotest sign of a cold.
Every year I freeze elderberries, they are meant to be particularly good in boosting the immune system, I think thats why this Sambucol stuff is so popular (google it), its a elderberry extract.
If you can get hold of elderberries next autumn, they grow just about everywhere, do yourself a favour, freeze them, then you can cook them and serve with ice cream or cream for dessert YUM, but any berries are good, you can buy frozen berries quite cheap from most supermarkets.
And I make lots of soups, using home made chicken stock, chicken soup is supposed to make you feel better when you are poorly with cold and flu, but I think its therapeutic any time.
I will post a few delicious soup recipes in the low carb recipes forum as soon as the school holidays are over.
Hope everyone stays healthy x
