How To Manage Food Allergy with Functional Nutrition

Functional Nutrition for Food & Fruit Allergies

Have you ever taken a bite from an apple and felt your mouth get itchy? Did a tasty banana cause your tongue or throat to swell? If so, chances are you have oral allergy syndrome, or pollen-food allergy. It happens because your immune system can’t tell the difference between proteins in these foods and pollen. The symptoms are usually itching, tingling, and swelling, mostly to the mouth, lips, and throat.

Food allergies and food intolerances has risen exponentially within the past decade. And allergy-friendly aisles have become commonplace in grocery stores.  Many schools and restaurants offer dietary accommodations for individuals with food allergies and intolerances. However, food allergies and intolerances have not always been such a big concern. In fact, it is only within the past decade that these conditions have skyrocketed. Between 1997 and 2011, IgE-mediated food allergies increased by 50 percent in American children.  In addition, research has found that more than 20 percent of the population of industrialized countries, including the United States, United Kingdom, Australia, and China, suffer from food allergies or intolerances.

What Is Allergy

An allergy is defined as the immune system reaction to a substance that’s not typically harmful coming in contact with or entering your body. These substances are called allergens and can include foods, pollen and grass, and chemicals.

What Is a Food Allergy (OAS)

Food or fruit allergy (OAS) is an allergic reaction to certain proteins in a variety of fruits, vegetables and nuts. The symptoms include itching and burning of the lips, mouth and throat. In more serious reactions, there may be swelling of the mouth, back of the throat and windpipe as well as hives.

Oral Allergy Syndrome OAS occurs from cross-reactivity between food and pollen. People who experience OAS usually also have seasonally hay fever symptoms as well. What happened is that the proteins in the foods look similar enough to the pollen proteins that your immune system causes an an allergic reaction or makes an exiting one worse. Usually the symptoms are mild, localized and dissipate pretty quickly, but they can cause enough discomfort to make you want to avoid that food.

Common Causes of Fruit Allergies

The most common pollens that cause this cross-reactivity are from birch, grasses and ragweed. Since the pollen production of these plants is seasonal, OAS symptoms can often increase or decline as the seasons change too. These are some of the most common foods that can cause OAS:

  • Birch pollen

The fruits and vegetables most commonly related to birch tree are apples, peaches, prunes, apricots, cherries, kiwi, pears, plum, carrots, celery, almonds, hazelnuts and peanuts

  • Grass pollen

The major Grass pollen fruit are: celery, melons, oranges, peaches, tomato.

  • Ragweed pollen
  • Many people who experience OAS are sensitive to pollen or latex. They may react to some other fruits such as passion fruit, fig, mango, kiwi, pineapple, acerola, coconut, date. grape, lychee, persimmon, papaya, avocado, pomegranate and strawberry.

The major ragweed pollen fruits are banana, cucumber, melons, sunflower seeds, zucchini.

Common Causes of Food Allergy

The most common allergenic foods that account for about 90 percent of all food allergies are:

  • eggs
  • fish
  • milk
  • nuts from trees (including hazelnuts, walnuts, almonds, and Brazil nuts)
  • peanuts (groundnuts)
  • shellfish (including shrimps, mussels, and crab)
  • soya
  • wheat

European countries have additional top allergens that include sesame, celery, lupin (a legume), and mustard.

Common Symptoms

OAS and fruit allergies can trigger symptoms that range from uncomfortable to severe and even life-threatening.

Common signs and symptoms include:

  • itching or tingling in the mouth
  • swelling of tongue, lips, and throat
  • sneezing and nasal congestion
  • lightheadedness
  • nausea
  • abdominal pain
  • diarrhea

In some cases, a life-threatening reaction called anaphylaxis may occur.

  • throat swelling
  • airway constriction
  • rapid pulse
  • dizziness
  • loss of consciousness
  • low blood pressure
  • shock

Food Intolerance

For some people, reaction to food isn’t a true allergy but rather a food intolerance. Because food allergies and food intolerances often have similar signs and symptoms, they can be mistaken for each other.

Many factors can cause a food intolerance, such as:

  • irritable bowel syndrome (IBS)
  • lactose intolerance
  • non-celiac gluten sensitivity
  • food additives, such as sulfites used for preserving dried fruit
  • psychological factors

How to Manage Food Allergies

  1. Consult with some allergy doctors
  • Do some allergy tests to identify the allergens that cause you have allergic reactions.
  • You may want to consider immunotherapy: Allergy “shot”, or under-the- tongue drops can be the good options.
  • Work with a Functional Nutritionist

Minimize allergy symptoms by using alternative approaches.  Instead of only treating the allergy symptoms, work with a holistic functional nutrition counselor to find out the root-cause to your fruit or food allergies. Develop a strategic plan to modify your diets, advanced nutrition supplements and lifestyle modification to minimize the symptoms. By detoxing and removing non-negotiable from the body system, improving immune system, modifying food ingestion, modifying lifestyle, bringing the deficiency to efficiency with key nutrients. Gradually and slowly your body can heal naturally itself from inside out.

Human body system is a big network. All parts of the organs are working together and correlated each each. When one part is out or order, the other part will not be happy and it will not be willing to work hard to keep you happy and healthy.  Of course, it will not function well. So let’s find out what food or fruit trigger your OAS symptoms; let’s find out which part of body system need to be repaired or replenished.

If you have food or fruit allergies, or if you have any other health challenge, please don’t be hesitated to email me, a holistic functional nutrition counselor, Wei Wei Ning via LifetsyleMedicine4U@Gmail.Com

The following is a good example of how I help one of my friends minimize her food & fruit allergies. Hope it will motivate you to see a new light of alternative approach to help you and your loved ones recover from health challenges and live a new life, a life of health, wellness, fit and longevity.

Step I. Remove Non-Negotiables

  • Identify problem foods and keep them in your diet journal
  • Avoid the foods or fruits that can cause you discomfort from your diet
  • Avoid the food that cause inflammation
  • Avoid Processed food

The pro-inflammatory sugars, trans-fats and additives are found in processed foods, baked goods and candies. They can keep stimulating your immune system

  • Dairy

Dairy can trigger mucus already rampant with allergies

  • Gluten

Gluten is found in bread, bakery and candies. When a person with celiac disease or gluten sensitivity eats gluten, the immune system jumps into action, causing inflammation and allergic reaction. The inflammation can affect the body’s organs and soft tissue.

  • Wheat

Wheat is found in many foods such as bread, and bread crumbs, cakes and muffins, cookies, cereals, pasta, crackers, soy sauce, ice cream, hot dogs, cold cuts, dairy, natural flavors, gelatinized starch,, modified food starch, vegetable gum, etc.

  • Red wine

Red wine is more likely to have lipid transfer proteins that cause notable allergic reactions that white wine is.  This is because red wine is fermented with protein-filled grapes skins while white wine is not.

  • Avoid Spicy Foods

Spicy foods create an outpouring of histamine

  • Avoid Raw Foods

Since OAS occurs in raw foods and fruits, try to avoid the food in raw forms is highly recommended.  

Step II. Improve Diets

No food is a proven cure. But fruits and vegetables are good for your whole body. They’re full of nutrients that can keep you healthy. They may also protect you from seasonal allergies.-

  • Eat cooked food & fruit

Usually cooking the food will change the protein structure enough that your body will not react. If a food cannot be eaten in cooked form, e.g., melons, you might choose to avoid eating those foods if they cause intolerable symptoms.

  •  Sprinkling the cut-up fruit with lemon juice and letting it sit for a few minutes may also work.
  • Using frozen fruits and veggies in your smoothies
  • Peel the skin of the fruit
  • Eat Onions, peppers, berries, and parsley

Onions, peppers, berries and parsley all have quercetin. Histamines are part of the allergic response. Quercetin is a natural plant chemical, that may reduce histamine reactions.  

  • Kiwi 

Kiwi is a fuzzy fruit rich in vitamin C. It can also cut down on histamines. You can get Vitamin C from lots of foods, including oranges and other citrus fruit.

  • Pineapple 

Pineapple has an enzyme called bromelain. According to Lawrence Rosen, MD, bromelain can reduce irritation in allergic diseases such as asthma.

  • Kefir

Kefir is a yogurtdrink that contains probiotics. These are good-for-you bacteria that live in your gut. Rosen says they may help prevent and even treat seasonal allergies. You can get probiotics in fermented foods. Look for yogurts that say “live active cultures” on the label. Sauerkraut and kimchi are also good sources. 

  • Local Honey

The research shows that mixing some local honey helps you head off allergies. “If you take small doses of the honey early in the season,” Rosen says, “you may develop a tolerance toward pollen in your area.”

  • Eat a Whole-Foods Diet

Whole-Foods are organic, none GMO and additives.  The nutrient-dense diet may have additional protection against food allergies and intolerances. Whole foods are generally those that remain close to their state in nature. They do not have additives such as sugars, starches, flavorings, or other manufactured ingredients. They are not primarily produced in a factory; in this way, they are the opposite of processed foods. Because they are not manufactured, they are not manipulated to be addictive. Choosing mostly whole foods will provide a nutritious diet and one that is probably higher in fiber.

  • Eat a Low Salt Diet
  • Studies have found that eating a diet higher in salt may be associated with more severe asthma, and small studies have found that eating a low-salt diet can improve lung function, decrease symptoms, and reduce the need for medications in people with asthma.
–       Sinus-Clearing Spices

Spicy foods and with a little kick can help kick out allergy symptoms. Anise, fennel, horseradish, and hot mustard can all act as natural decongestants. They offer allergy relief by stimulating the mucosal cilia to help break up congestion.

–       Eat Foods Rich in Vitamin E

Studies shows that vitamin E can decrease allergy-related inflammation.

  • Eat cold-water fish

Cold-water fish like salmon is rich in omega-3 fatty acids. Studies have been shown that omega-3 fatty acids from cold-water fish have anti-inflammatory effects that may help with allergy relief.  

  • Walnuts & Flaxseeds

Walnut and flaxeeds are rich in inflammation-fighting omega-3s that will help with allergy symptoms.

Step III. Bring Deficiency to Sufficiency

Improve Gut Microbios by Detoxing the Body System

Nutriclean 7 Day Cleanzer

If you eat, drink and breathe the air you have toxins within your body. Detoxification is a great way to remove toxins from the body system, increase energy levels,  improve vitality, decrease food & fruit allergens, revitalizing your immune system.


Aloe Vera Juice

Aloe Vera plant is considered a miracle plant because of the multitude of curative and healing benefits. Aloe Vera leaves are filled with a gel containing vitamins A, B1, B2, B3, B6, B12, C and E, and folic acid, as well as a wide variety of minerals copper, iron, sodium, calcium, zinc, potassium, chromium, magnesium and manganese.

Aloe is safe to use externally and internally, and many around the globe use this plant for treating various health conditions, from minor burns to cancer. If Aloe can impact cancer, imagine what it can do to improve common allergy symptoms like:

  • fatigue and brain fog
  • lung and nasal issues
  • itchy eyes and throat
  • gas, bloating and skin flare-ups

Factors associated with allergies:

  • digestion, constipation and bowel health
  • reaction to pollen and other airborne allergens
  • antibiotics and prescription drug reliance

Aloe Vera provides flavonoids and aids nutrient absorption. The whole leaf Aloe Vera plant contains over 100 actives, including Yellow Sap which works quickly as a digestive bitter supporting stomach acid. Together with other essential properties, it improves vital core nutrient absorption, while easing occasional indigestion discomfort and revving up the body’s metabolism.

Why Ultimate Aloe Vera

Aloe Vera has an acidic pH which helps to encourage the body to secrete the exact amounts of hydrochloric acid to improve digestion and absorption. Many allergy sufferers have weak digestion which does not allow the body to receive the nutritional benefits from foods and supplements.

Whole leaf aloe can help to provide relief from allergic responses by strengthen connective tissue called collagen. Weak collagen tissue in nasal passages, lung tissues, and intestinal tract cell walls allow foreign invaders to enter the blood stream and cause an allergy response.

By drinking whole leaf Aloe Vera juice daily, you are providing the body with needed flavonoids (plant phyto-nutrients,) and you may begin to reverse allergy sensitivity.

Once these flavonoids and other nutrients are absorbed at the cellular level, the body can support collagen and tissue structure development to screen out the allergies. The glycomannan complex, present in whole leaf aloe vera, helps to provide additional n strengthening of tissue cell walls.

Natural anti-inflammatory and analgesics, found in the yellow sap, help to reduce swelling, pain and skin irritation. Campesterol, B-sitosterol, lupeol, and salicylic acid help to promote additional allergy relief.

Fiber Powder

Prebiotics support the growth of probiotics, which help keep bad bacteria under control. By supporting the good bacteria, prebiotics help to prevent diseases, improve digestion and nutrient absorption. Especially minerals, and enhance the immune system. Good prebiotics are onions, leeks, Jerusalem artichokes, and asparagus.

Why Nutriclean Fiber Powder

NutriClean Advanced Fiber Powder delivers top quality soluble fiber with beneficial probiotics, which promotes the growth of good bacteria in the colon, keeping things in balance in terms of microorganisms.

Verified by our in-house scientists, NutriClean Advanced Fiber powder contains one of the most advantageous mixtures of L-glutamine, inulin, Fibersol-2 and probiotics. NutriClean Advanced Fiber Powder’s probiotic blend supplies 1.5 billion healthful microorganisms. Taking a good-quality colon and digestive cleansing system and detoxification regimen may be beneficial to clear out waste products and balance the bowel.

Digestive Enzymes with Probiotics

The root cause of food intolerance is an inability to digest certain foods due to lack of an inherent digestive enzyme—resulting in digestive discomfort. That’s when supplemental digestive enzymes can be especially helpful.

Why Isotonix Digestive Enzymes with Probiotics

Isotonix Digestive enzymes with probiotics, including DigeZyme – a blend of amylase, protease, cellulase, lactase and lipase – and Lactospore (Bacillus coagulans). Digestive enzymes help your body break down food to utilize the complete spectrum of nutrients in the food you eat, resulting in a more complete digestive process and better nutritional absorption. The addition of probiotics helps promote a healthy intestinal tract environment. Besides supporting a healthy digestive tract and absorption of nutrients. Digestive Enzymes with Probiotics helps maintain epithelial structure and barrier function and supports healthy skin, helps maintain healthy cholesterol levels, supports healthy immune functions, and may help ease occasional stomach upset.


Probiotics have been proven to provide both anti-inflammatory and anti-allergic effects, especially when given in pregnancy and breastfeeding,” says William Silvers, MD, an allergist in Englewood, Colo., and chairman of ACAAI’s sports medicine committee. In a recent study published in the British Journal of Dermatology, mothers who drank milk containing a probiotic supplement during and after pregnancy were able to cut the chances their babies would develop eczema, a condition related to other allergies, by nearly half. Additionally, an Italian study found that young children (aged 2 to 5) with allergic rhinitis who drank fermented milk containing the probiotic Lactobacillus casei for 12 months experienced fewer allergic episodes than children who drank a placebo.

The therapeutic use of probiotics could truly be a breakthrough in the prevention and treatment of food allergies and intolerances, decrease atopic sensitization, and potentially reverse sensitization, prevent and reverse food allergies.

Probiotics upregulate gut microbes, the bacteria normally present in the gut that are responsible for interacting with the immune system to promote tolerance of foods.

Probiotics also reduce intestinal permeability, thus decreasing antigen uptake from the intestinal lumen; this phenomenon is the first step in food allergen sensitization.

Probiotics increase intestinal IgA, an immunoglobulin associated with immune tolerance and a reduced risk of IgE-mediated allergic diseases. 

Probiotics may ameliorate food intolerances by crowding out pathogenic bacteria and reducing intestinal inflammation.

Why Probiotics 10

Probiotics-10 utilizes LiveBac technology, a unique tableting process to deliver high-viability probiotic products that are far less susceptible to damaging environmental factors. This extends the active shelf life of our product.

Probiotics-10 also defends against the effects of stomach acid during digestion with BIO-tract. Probiotics may become ineffective when they meet stomach acid during the digestive process. Meaning, when you take a probiotic supplement, the number of viable strains and CFUs may greatly reduce by the time they are absorbed into the body. BIO-tract protects probiotic organisms from stomach acid on their way to the intestinal tract, supporting a significantly higher percentage of organisms to reach the intestine alive.

DNA Miracles Flora Melts

DNA Miracles Flora Melts are a delicious dietary supplement for children, delivering probiotic and prebiotic support for digestive and immune health. They provide a unique group of prebiotic functional starches paired with Lactospore, a probiotic for optimal digestive and intestinal microflora health in children and adults.

Each serving of Flora Melts features LactoSpore, a spore of the probiotic strain Bacillus coagulans, that provides strong immune and intestinal defense while surviving stomach acid and the harsh gastrointestinal environment. In addition, DNA Miracles Flora Melts contain one gram of soluble fiber and three different sources of prebiotics – a blend of Jerusalem artichoke, apple fiber and chicory root fiber – to promote optimal health.  By offering three powerful, yet different prebiotic fibers, DNA Miracles Flora Melts also support healthy metabolism.

Vitamin D

Vitamin D is well-known the sunshine vitamin. It has long been linked to allergies. Studies have shown that children who live farther from the equator are more likely to develop allergies and suffer higher rates of hospital admissions due to allergic reactions.  From November through February, it is thought that people in the north (at a latitude above 35°) cannot synthesize vitamin D because they are not sufficiently exposed to sun.

Children and adolescents with lower levels of vitamin D in their blood are more sensitive to allergens than those with higher vitamin D levels.

Vitamin D likely reduces the chance of developing allergies because of its effect on the immune system, which has been demonstrated in a number of ways. Vitamin D has been shown to quickly rid the body of hives and other allergy symptoms. This vitamin is critical to the proper functioning of T-cells, which are a major part of the immune system.

Vitamin C

Vitamin C boosts the immune system. It also acts as a natural antihistamine. According to a 2018 study on vitamin C in the treatment of allergies, oxidative stress plays a key role in allergic diseases. As vitamin C is a powerful antioxidant and anti-inflammatory, it may act as a treatment for allergies.

The researchers observed that high doses of intravenous vitamin C reduced allergy symptoms. They also reported that a deficiency in vitamin C might lead to allergy-related diseases. Another study from 2000 suggests taking 2 grams (g) of vitamin C daily to act as an antihistamine.


Magnesium is involved in many biological processes within the body. Magnesium deficiency causes many disorders, including impairment of immunity and skin allergy reactions. Magnesium deficiency in experimental animals, mainly rats, leads to characteristic hyperemia, an increase in IgE, neutrophilia and eosinophilia, an increase in the level of proinflammatory cytokines, mastocyte degranulation, histaminemia, and splenomegaly.


Bromelain is an enzyme found in the core and juice of pineapples and is also available as a supplement.

Bromelain is a popular natural remedy for swelling or inflammation, especially of the sinuses and following injury or surgery.

Researches on mice suggests that bromelain can reduce allergic sensitization and allergic airway disease thanks to its anti-inflammatory and anti-allergic properties.

People who are allergic to pineapple should avoid bromelain.


Turmeric is well-known as an anti-inflammatory powerhouse for a good reason. Its active ingredient, curcumin, has been linked to reduced symptoms of many inflammation-driven diseases, and could help minimize the swelling and irritation caused by allergic rhinitis. May 30, 2019

Turmeric has multiple health restoring properties. It has been used in treating several diseases including several respiratory disorders. Turmeric is a common spice used in the culinary preparations in South and East Asian countries. The active component of turmeric is curcumin, a polyphenolic phytochemical, with anti-inflammatory, antiamyloid, antiseptic, antitumor, and antioxidative properties.

Curcumin was reported to have antiallergic properties with inhibitory effect on histamine release from mast cells. The effectiveness of curcumin in allergy and asthma has been further investigated using a murine model of allergy. The results indicate a marked inhibition of allergic response in animals treated with curcumin suggesting a major role for curcumin in reducing the allergic response. 

Peppermint Oil

Peppermint oil is one of the very few essential oils that can be safely ingested. 2-3 drops in a glass of water is the normal dose for an upset stomach.

Eucalyptus Oil

Eucalyptus oil to soothe exhausted body, stress & mental sluggishness. It is anti-inflammatory, analgesic and works well in treating joint, rheumatism, fibrosis, stiff muscles and muscle pain. For germicidal properties, it is used in dental hygiene products to treat plaque and other dental infections. This oil is also beneficial in treating acne and skin infections.

Step III. Lifestyle Modification

  •  Drink plenty of water

Histamine is a major driver of allergic symptoms. It is increased when you dehydrated. So be sure to stay well-hydrated with water or non-caffeinated herbal teas throughout the day.

  • Reduce Stress

Stress increases inflammation, which can make your system to be more reactive to allergens. Try to minimize your stress level my doing Yoga and Meditation will help minimize allergy symptoms.

  • Exercises

Exercise isn’t a cure for your allergies, but physical activity can help to soothe some of your symptoms. Exercise can improve blood flow and activate cells and boost immune system.
