I'm allergic to fruits and most vegetables.

This does sound odd that someone would be allergic to all fruits and most vegetables, but I guess it's possible. If it's an issue of not "liking" certain vegetables or fruit, then that's a different story. Try some protein shakes maybe, or drink the fruit and veggies in smoothie form if you don't like it raw. You can eat whatever you want really as long as you stay in a calorie deficit. and drink lots of water. That's all I got.

allergic to fruits and vegetables?? you mean u have some sort of anxiety issue with them right? don't think the human body would reject some blueberries and break out in rashes or throat closing up.

It's actually possible. Rare, I think though. I am actually allergic to honey dew mellon. If I eat too much my throat burns and becomes red and itchy.

I'm also very allergic to most fruits, so it's a real allergy. Do you have seasonal allergies? There is a syndrome thats caused by having intense seasonal allergies, specifically when you are highly allergic to birch or sage. They have a very similar protein that matches and our body thinks its the allergen.

I'm allergic to apples, peaches, pears, plums, cherries, nectarines, etc. and figs. and also raw nuts. Some people are also allergic to mangos and bananas, although I'm not. Also there are a few veggies on the list, specifically carrots. I can eat carrots peeled no problem. Most of the time the protein is in the skin.

I can eat nearly ALL these fruits when cooked, as the protein that causes the allergy is easily broken down.. hence the ability to eat applesauce, apple pie etc. its been cooked. I get the same as you, a very itchy sore SORE mouth, like intense sores all over the roof of my mouth, and down my throat. Figs cause my throat to swell so I think that one is different.

Do you have a problem with berries? I can't strawberries unless freshly picked as there is a fungus that gives me an itchy mouth.

if you can eat berries, then those are super good for you. Blueberries have a lot of fiber too.

OAS produces symptoms when an affected person eats certain fruits, vegetables and nuts. Some individuals may only show allergy to only one particular food, and others may show an allergic response to many foods.[8]
Individuals with an allergy to tree pollen may develop OAS to a variety of foods. While the tree pollen allergy has been worked out, the grass pollen is not well understood. Furthermore, some individuals have severe reactions to certain fruits and vegetables that do not fall into any particular allergy category. In recent years, it has also become apparent that when tropical foods initiate OAS, allergy to latex may be the underlying cause.[9]
Because the allergenic proteins associated with OAS are usually destroyed by cooking, most reactions are caused by eating raw foods. The main exceptions to this are celery and nuts, which may cause reactions even after being cooked.
Cross reactions[edit]
Allergies to a specific pollen are usually associated with OAS reactions to other certain foods. For instance, an allergy to ragweed is associated with OAS reactions to banana, watermelon, cantaloupe, honeydew, zucchini, and cucumber. This does not mean that all sufferers of an allergy to ragweed will experience adverse effects from all or even any of these foods. Reactions may be associated with one type of food, with new reactions to other foods developing later. However, reaction to one or more foods in any given category does not necessarily mean a person is allergic to all foods in that group.
Alder pollen: almonds, apples, celery, cherries, hazel nuts, peaches, pears, parsley, strawberry, raspberry
Birch pollen: almonds, apples, apricots, avocados, bananas,[10] carrots, celery, cherries, chicory,[11] coriander, fennel, fig,[12] hazel nuts, kiwifruit, nectarines, parsley, parsnips, peaches, pears, peppers, plums, potatoes, prunes, soy, strawberries, wheat; Potential: walnuts
Grass pollen: fig,[12] melons, tomatoes, oranges
Mugwort pollen : carrots, celery, coriander, fennel, parsley, peppers, sunflower
Ragweed pollen : banana, cantaloupe, cucumber, green pepper, paprika, sunflower seeds/oil, honeydew, watermelon, zucchini, echinacea, artichoke, dandelions, honey (if bees pollinate from wild flowers), hibiscus or chamomile tea
Possible cross-reactions (to any of the above): berries (strawberries, blueberries, raspberries, etc), citrus (oranges, lemons, etc), grapes, mango, figs, peanut, pineapple, pomegranates, watermelon

Was going to say, sounds like Oral Allergy Syndrome.

I would speak further with an allergist who understands this. Not all totally get it. Find out if there is a way to see what fruits and vegetables you can handle cooked instead of raw. Go from there. Hopefully you can find a few. If nothing else, it will broaden your options which is NEVER a bad thing!
