Food Additive Sensitivity
Adverse reactions to artificial food additives including MSG, aspartame, artificial colors, and preservatives — managed by eliminating all processed and packaged foods, reading labels vigilantly, and eating only fresh whole foods: fruits, vegetables, whole grains, legumes, and nuts.
Also known as: MSG sensitivity, food additive reaction, artificial additive intolerance, preservative sensitivity, palpitations (definition: sensation of rapid or irregular heartbeat), nausea (definition: feeling of sickness or urge to vomit)
📝 At a glance
Likely root causes: Monosodium glutamate (MSG) — found in restaurant food, chips, canned soups, frozen meals, and hundreds of processed foods under disguised names (hydrolyzed vegetable protein, yeast extract, natural flavors, etc.).; Aspartame (NutraSweet, Equal) — in diet foods and beverages.; Artificial colors (FD&C dyes)..
First thing to try: Eliminate the offending additive completely.
See a doctor if: See a doctor if symptoms are severe, persistent, or worsening, or if you are unsure — natural supports are meant to complement, not replace, professional care.
🔎 Start with the cause
Lasting relief rarely comes from covering a symptom. First find what is feeding the problem, change what you can, and then help the body do what it was designed to do — heal.
Likely root causes
- Monosodium glutamate (MSG) — found in restaurant food, chips, canned soups, frozen meals, and hundreds of processed foods under disguised names (hydrolyzed vegetable protein, yeast extract, natural flavors, etc.).
- Aspartame (NutraSweet, Equal) — in diet foods and beverages.
- Artificial colors (FD&C dyes).
- Sulfites (in dried fruits, wine, preserved foods).
- Nitrates/nitrites (in processed meats).
- BHT/BHA preservatives.
Change what you can
- Eliminate the offending additive completely.
- Read ALL food labels — MSG appears under many disguised names including: hydrolyzed vegetable protein, hydrolyzed protein, plant protein extract, sodium caseinate, calcium caseinate, yeast extract, textured protein, autolyzed yeast, natural flavors, malt extract, bouillon, broth, stock.
- Eat only fresh whole foodsFoods close to how they grow in nature, with little or no processing. More →: fruits, vegetables, whole grains, legumes, and nuts.
- Cook from scratch with whole ingredients.
- Plan and prep meals ahead so you're less tempted by convenient packaged foods when you're busy or hungry.
- When eating out, ask how dishes are prepared and choose simple, freshly cooked options over sauces and premade mixes.
- Introduce one new food at a time when rebuilding your diet, so it's easier to spot a reaction.
- See a doctor or allergist if reactions are severe, involve swelling or trouble breathing, or if you're unsure which additive is the trigger.

This foundational approach helps identify a true personal trigger before assuming any single additive is the cause.
How to do it ▾
Why it works: Removing processed and packaged foods for a period, then reintroducing one additive at a time, can help identify a personal trigger since lab testing for additive sensitivity is limited.
- For 2-3 weeks, eat only fresh, whole foods you prepare yourself: fruits, vegetables, whole grains, legumes, and nuts.
- Avoid packaged, canned, and restaurant foods where additives are common and often hidden.
- Keep a daily journal of what you eat and any symptoms that follow.
- After the elimination period, reintroduce one suspected additive at a time, several days apart, and note any reaction.
2-3 weeks elimination, then gradual reintroduction · Daily during the trial period
Caution: Keep a written log — sensitivity to additives can be hard to pin down and easy to imagine without careful tracking. Do not restrict a child's diet drastically without guidance from a pediatrician, since growing bodies need consistent nutrition.
When to get help: Seek emergency care immediately for swelling of the lips, tongue, or throat, difficulty breathing, or widespread hives after eating, which can signal a serious allergic reaction.

A more targeted step for those whose symptoms include wheezing or hives after eating preserved foods.
How to do it ▾
Why it works: Sulfites, used to preserve dried fruit, wine, and some prepared foods, are a documented trigger for asthma flares and hives in a subset of sensitive people, so limiting exposure can reduce symptom frequency.
- If you have asthma or hives that seem to follow certain foods, note whether dried fruits, wine, or prepared salads are involved.
- Choose unsulfured dried fruit and freshly prepared foods instead of processed versions when possible.
- Carry any prescribed rescue medication (such as an inhaler) if you have asthma, in case of accidental exposure.
- Discuss a personal sulfite sensitivity with your doctor or allergist for formal evaluation.
Ongoing habit · Every time you shop or eat out
Caution: People with asthma should never stop or delay prescribed asthma medication in favor of dietary changes alone. Sulfite reactions can occasionally be severe — anyone with a known reaction should carry emergency medication as advised by their doctor.
When to get help: Seek emergency care immediately for wheezing, difficulty breathing, throat tightness, or widespread hives after eating sulfite-containing foods.

Once a trigger is identified, this habit helps you avoid it long-term.
How to do it ▾
Why it works: Many additives, especially MSG and sulfites, appear under many different ingredient names, so learning to recognize them on labels helps you avoid a known personal trigger going forward.
- Learn the common disguised names for additives you react to (for MSG: hydrolyzed vegetable protein, yeast extract, autolyzed yeast, natural flavors; for sulfites: sodium metabisulfite, potassium bisulfite).
- Read every ingredient label before buying packaged food, especially soups, dried fruit, wine, and processed meats.
- When eating out, ask how food is prepared and whether particular additives are used.
- Favor foods with short, recognizable ingredient lists.
Ongoing habit · Every time you shop or eat out
Caution: Ingredient lists can change, so re-check labels on products you buy regularly. Restaurant staff may not always know every ingredient — when reactions are severe, it is safest to prepare food yourself.
When to get help: Seek emergency care immediately for swelling of the lips, tongue, or throat, difficulty breathing, or widespread hives after eating.

“Disease is an effort of nature to free the system from conditions that result from a violation of the laws of health... In case of sickness 1cause should be ascertained, 2go to work intelligently to remove the disease. 3Unhealthful conditions should be changed, 4wrong habits corrected. 5Then nature is to be assisted in her effort 6to expel impurities and 7to re-establish right conditions in the system.”
🌿 Overview
Food additives — including monosodium glutamate (MSG), aspartame, artificial colors, preservatives, and flavor enhancers — can cause a wide range of adverse reactions in sensitive individuals. MSG and aspartame are classified as excitotoxins — chemicals that over-stimulate neurons and can cause brain cell damage. Many of these additives are hidden under multiple names on ingredient lists. The safest approach is to avoid all foods containing additives and eat only whole, unprocessed foods.
Some people notice symptoms — such as headaches, flushing, digestive upset, hives, or feeling unwell — that they associate with certain food additives, like particular colorings, preservatives, sulfites, or flavor enhancers. Genuine reactions to specific additives do occur (sulfites, for example, can trigger symptoms in some people, especially those with asthma), though true additive sensitivities are less common than often assumed, and many suspected reactions have other explanations.
The practical approach is observation and a varied, whole-food diet: keeping a simple food-and-symptom diary can reveal whether a particular additive genuinely tracks with symptoms, and eating mostly fresh, minimally-processed foods naturally reduces additive intake while improving nutrition overall. Because food reactions overlap with many conditions, and because cutting out foods unnecessarily can be limiting, it is worth getting persistent or significant symptoms evaluated by a doctor or dietitian. Importantly, any reaction involving difficulty breathing, swelling, or other signs of a true allergy is a medical matter needing prompt attention.

🍽️ Eating to help
Food is one of the gentlest medicines — small, steady changes help most.
Eat exclusively whole, fresh foods. Cook from scratch. Avoid restaurant food and all packaged, processed, preserved foods. Read every label — if the ingredient list is long and unrecognizable, avoid the product. Organic whole foods are the safest choice.
⚖️ Good to know
- MSG sensitivity can mimic many other conditions — keep a food diary to identify patterns.
- Aspartame reactions are well-documented and include seizures, vision problems, and neurological symptoms — avoid it completely.
- Children's brains are especially vulnerable to excitotoxins.
- Sulfite allergy can trigger asthma attacks in sensitive individuals.
