Recent reports noted the possible dangers of kissing to people with food allergies. A study at the University of California at Davis found that even a kiss on the check can cause an allergic response such as a hive or even anaphylactic shock if the person has recently eaten the specific food.
You hear very little about it, but food allergies send some 30,000 people to the hospital every year and about 200 die. That is three times the number that die from bee stings.
If someone in your family has food allergies, it may be wise to keep kissing to a minimum if you eat the offending food. The most common trigger foods includes tree nuts, peanuts, and sea foods,
While we usually think of kissing as being a way to express affection, it can also be a way of spreading disease. Both bacteria and viruses can be spread through the lips and saliva.
Among the list of contagious diseases that may be spread by kissing are mononucleosis (the kissing disease), Herpes, Hepatitis B, cold sores, Meningitis, as well as the common cold.
Dentists warn that you can even pass on the risk of cavities, especially if it is 20 minutes after dessert when the levels of sugar or bacteria in the saliva are highest.
While brushing will reduce this risk of spreading germs, there is no protection against diseases such as herpes or mono. You just may want to be very careful with whom you share your affection.
