The major allergen from peach, is a 9-kDa allergen belonging to the family of lipid-transfer proteins which has been proven to be cross-reactive to homologous proteins both in Rosaceae fruits and in other plant derived foods.Peach allergy is the most common form of IgE-mediated hypersensitivity to fresh fruits.Peach allergy is rarely observed as an isolated allergy, and most patients present with some other food or inhalant allergies. The foods most frequently associated are other members of the Rosaceae family, such as apple and pear, and apricot, cherry and plum. According to clinical observations, apple allergy is the most frequent food allergy associated to peach allergy.
The allergenicity of peach juices and nectars could only be reduced by lye peeling of fruits and ultrafiltration of juices, respectively.

I have terrible allergies/intolerances to inhalants, chemicals and foods. I am currently only able to eat freshly cooked beef, pork, chicken, black beans, field peas, carrots, cauliflower, celery, white rice. That is it...no fruits no wheat, eggs, yeast, dairy, green vegetables ( can t tolerate the chlorophyl), no seasonings beyond salt. I cannot be tested by allergist because it takes 1 week to test one thing at a time. The last time they tried to test multiple sensitivities my arm swelled up twice its size and they all panicked. Could these allergies be related to thyroid or adrenal gland issues? I have so many allergies/intolerances could they be related to a deeper problem? and no i have NO medical problems except for these allergies

Hello doctor i have a friend here who is suffering from a very severe case of dust allergy. He s had his tonsils removed when he was a child and that proved to be a mistake as his doctor says. When he was 11 years old, he suffered an allergic attack and he was hospitalised. He lay in coma for 2 days. His doctor says that he has extremely low resistance and another attack like that may prove fatal. Now he is 19 years old. He gets very high fever frequently, like once in 2 weeks, and a bad cold almost every day. He gets small attacks often. These are seemingly caused by nothing, they are always sudden. He can t stand in even a mild dusty place without coughing continously for 30 minutes. He has a high eosinophil count of 13% and his doctor has told he cannot be cured unless he builds his resistance. He s been a weak chld since birth. He takes evening walks and eats fruits to improve his resistance. He absolutely refuses to take up meditation as he believs its of no use, and nothing can cure him. I get scared now everytime he gets an attack cos he speaks like it might be his last breath. Please help.

I've been watching my blood pressure. Sometime its normal, sometime not. My pulse also is doing that. This reading is 137/84 and pulse is 45. I was just wondering how lower your pulse can go and be okay? Reading earlier was 139/76 and pulse 110. One of my high ones was 133/94 and pulse 46. I have been taking prednesone since yesterday in a tapering dose due to an unknown allergic reaction under my eyes/swelling. But my blood pressure has been doing the high/normal stuff for some time.
