<p>Anyone become allergic later? I am having symptoms (itching , runny nose , sneezing) Very intensely about one day a week . I am wondering if I am suddenly allergic to nuts or tomatoes/ red peppers . </p>
<p>Any experiences? </p>
<p>Those wouldn’t be likely to be the symptoms of a food allergy. More likely something in the air.</p>
<p>They are listed as symptoms of food allergy. </p>
<p>Maybe you’re allergic to that day of the week. I myself am allergic to Mondays. :)) </p>
<p>If you have a list of suspected foods, and the symptoms as yet are not incapacitating, try excluding one at a time. Otherwise, there’s no way to figure out which one is the culprit. I would start with nuts.</p>
<p>The alternative is to get referred to an allergist and go through a scratch test (or whatever else they do these days).</p>
<p>My bro developed a severe allergic reaction to oregano and SisIL to mint as adults. H and S are developing allergies to shellfish. They cause hives and GI issues. H and D also have lactose intolerance and gluten intolerance. </p>
<p>When I was pregnant, had allergy to tomatoes and Parmesan cheese–thankfully resolved. </p>
<p>Natural Jewish , one of the leading allergy centers admits that elimination diets are best at pinpointing what you may be allergic to that you consume. Skin and blood testing is useful for things in the environment you may touch or engage but not for food allergies. Such testing can have many false negative and positives for foods. </p>
<p>As the parent of a kid who has a life threatening nut allergy, I say get tested. The itching…is it near your mouth/face/lips? Don’t risk another exposure…the second reaction is almost always worse in a true allergy, (note:many people use allergy when in fact intolerance is more accurate. A true allergy will usually cause increasingly worse reactions that are far more severe than the temporary inconvenience/discomfort of an intolerance…ie, intolerances may cause belly aches/headaches/general not feeling good symptoms, whereas allergies (especially nut/shellfish) can affect the respiratory system and cause life threatening issues). Intolerances and allergies can both develop at anytime in life, but certain allergies (again, nuts and shellfish in particular) are generally never outgrown. Whether it’s an allergy or an intolerance, your body is trying to tell you something. A visit to a good allergist is in order. If he suspects it is nuts, he will likely do bloodwork as a skin test can be risky in highly sensitive individuals. My D had a clueless allergist when she was a toddler (after an anaphylactic reaction) who did a skin test to confirm. Her arm blew up like a balloon! Her next doc said that it was borderline negligent to do that test in an office, without emergency life saving equipment on hand. So he did bloodwork instead. Sorry for the novel…too much experience in this area, unfortunately 
Good luck.</p>
<p>I don’t know about foods specifically, but you certainly CAN develop new allergies over time. I had no allergies as a kid and am now affected by pollen, mold or anything related to growing plants. And I live in the Pacific Northwest. Not fun. I hope you find the cause of your reactions.</p>
<p>Thanks all. Yes -itching is around my mouth , face and head. Seems really acute. That’s why I was thinking food
was a possibility. </p>
<p>If it is an allergy, itching/runny nose/sneezing are more commonly associated with external allergens such as pollens or environmental triggers rather than food allergies. True food allergies will typically cause swelling along the digestive track, difficulty breathing, and often hives. Oral allergy syndrome, which differs from an anaphylactic reaction, will usually cause redness in face, itching of mouth/throat/tongue and possibly hives. Oral allergy syndrome is typically not as dangerous,although it can proceed to anaphylaxis is some people. OAS is strongly correlated to pollen allergies - for example, I can’t eat apples, certain nuts, or carrots during birch pollen season as my birch tree allergy heightens my sensitivity to apples and carrots and nuts.</p>
<p>If you haven’t tried an over the counter antihistamine such as Claritin or Zyrtec you should. If that helps your symptoms, then seeing an allergist might make sense. Or the over the counter meds might be all you need.</p>
<p>You certainly can develop allergies at any point in your life, and there are some allergies that sometimes get better or go away in some people.</p>
<p>Food and other allergies can develop later in life. Mr B unpleasantly discovered that he became allergic to raw (not roasted) filberts when he turned 30 or so. The symptoms are scratchy throat, itchy lips and face, etc.</p>
<p>@veruca Better safe, than sorry. Keep a food diary, and eliminate one food at a time while you await an appt with an allergist. Since you have an idea of possible culprits, this should be doable. Keep plenty of allergy meds on hand just in case. </p>
<p>Sounds like a plan. Thanks everyone </p>
