In response to Gars and not necessarily the OP, most sweet things are made with refined sugars now which is a suppressant to the immune system in the body and increase the chances of infections in the body. As for the throat thing, there were studies that show that things like sugars, dairy (due to a protein in dairy called Caesin and Lactalbumin), as well, soy, alcohol will aggravate the membrane lining of the throat where the mucous producing glands are. This will further irritate the already sensitive throat and it will cause the mucous to drip back in the throat causing sore throats. Honey is usually a substitute as you would most likely see all those lemon-honey flavored cough drops at the Pharmacy. Honey is one of those rare food items that will last forever due to it's waxy coating that won't irritate the throat. It also has antibacterial properties.
As for cold drinks, I'm assuming it's due to various reasons. There was an article published last year about studies that showed the effects of hot drinks vs cold drinks in aiding of cold and flu symptoms. I don't believe it's the virus we're we're attacking considering viruses can not be cured, but it's the symptoms. As well there's been many cases that show cold drinks triggering bronchial asthma attacks, just simply due to the fact that the inflammation of the bronchial tubes are so sensitive that anything from dust to a sudden change in temperature can trigger an attack.
