Greeks are more likely to be allergic to milk than any of their European Union counterparts and also have a high sensitivity to products containing grapes, sesame seeds and peanuts, with Athenians suffering the most, allergy experts said yesterday. Almost a third of residents in the capital suffer from allergies, compared to 22 percent in other big cities and only 15 percent in the countryside, doctors said ahead of a conference on allergies which is due to begin in Athens today. According to recent studies, 25 percent of youngsters in Greece suffer from hay fever and 10 percent have skin allergies. Some 8 percent of children have food allergies. The doctors from the Greek Allergy and Clinical Immunology Society said the sterile environments in which we live and the use of antibiotics have weakened people’s immune systems.
