Andre's (Many) Food Sensitivities

This is the table of foods I am sensitive to and my responses to them.

Food Glutamic Acid Lactose Citric acid Sulphites Chocolate Beef
Type Metabolic disorder (Fast glutamate uptake/slow breakdown) Metabolic disorder (Lactase deficiency) Metabolic disorder (See notes) Metabolic disorder (Sulphite oxidase deficiency due to molybdenum deficiency) Metabolic disorder (Xanthine oxidase deficiency due to molybdenum deficiency) Unknown
Symptom Severity Mild Severe Mild Moderate Moderate Moderate
Dose Response Linear Step Linear Linear Step Step
Response Time Hours 3 hours (full stomach) 5–8 hours ½–1½ hours 5–8 hours 5–8 hours
Partial Recovery Time (After Onset of Symptoms) None – Always Functional 1 hour 1 hour None – Always Functional 1 hour 1 hour
Full Recovery Time 1 day 1 day 2 days 4 days 1 day 1 day
Obvious/Natural Sources None Milk, Cheese, Ice Cream Citrus fruit, pineapple, most berries, tomatoes None Chocolate, cocoa, cocoa butter Duh
Weird Ingredient Sources MSG Lactose (especially in medications), milk ingredients (very common in processed foods) Pectin, citric acid, citrate Sulphite (including metabisulphite), saccharin, acesulfame-K, yellow #5 (potentially any colour), wine, vinegar (all except white or malt), molasses, brown sugar (contains molasses), maple syrup, cold cuts/preserved meat, dried fruits, caramel colour, bottled citrus juice, certain preserved seafood None None
Preventative Measure None Lactase enzyme caplets, lactose-free equivalent Molybdenum supplement Molybdenum supplement Molybdenum supplement None
Behaviour without Preventative Measure Avoid Avoid Eat reduced quantities Avoid Avoid Avoid
Behaviour with Preventative Measure Avoid As much as desired, with food Eat moderate quantities Eat small quantities, occasionally Eat trace quantities Avoid
Notes Must be labelled, therefore easy to avoid Very aged cheeses (e.g., Parmesan) are effectively lactose-free Suspected pantothentic acid hyper-metabolism, but testing suggests not. Possibly molybdenum-related Must be labelled in Canada after August 2009; illegal on fresh produce

“Always functional” means that if I was experiencing these symptoms, I would be in pain, but capable of hiding it.

There are only four molybdenum-dependant enzymes in humans: xanthine oxidase, ferrodoxin, sulphite oxidase, and nitrate reductase. I suspect that I have a molybdenum processing disorder, but it doesn't really make sense. I have no symptoms of nitrate reductase deficiency (higher met-haemoglobin in the blood) and if I have xanthine oxidase deficiency, I should have trouble with a number of purine-rich foods, including pork and cheese, which I don't. Ferrodoxin might explain the citric acid sensitivity, but then how am I not dead? Admittedly, the deficiency must be small and the biochemistry must be complicated. This is my best hypothesis, but there aren't many tests I can do on my own at this point.

It's also worth noting that lactose-intolerance is wild-type and lactose-tolerance is the mutant phenotype.

The Elimination Diet

This is the elimination diet I followed to determine my sensitivities. My sister also used it and discovered she is sensitive to wheat, pork, and the mint-family herb. It's a composite of many I found online. Keep a journal of what you eat, approximate times, bowel movements, and any GI discomfort.


For two weeks (though plan for three since you will probably make mistakes the first week), eat only the following foods. You should have no symptoms at the end of those weeks.

Beans – green beans, wax beans, dried beans, chickpeas, lentils, peas, dried peas
Beet Family – beets, beet greens, Swiss chard
Cabbage Family – cabbage, bok choy, napa cabbage, broccoli, cauliflower, rapini, broccolini, mustard greens, collard greens, kholrobi
Carrot Family – carrots, parsnips, parsley, celery, celery root
Cooking Ingredients – tapioca starch, white vinegar
Fruits – olives, blueberries, grapes, apples, pears, dates, apple juice/cider/sauce if unsweetened
Grains – Rice, quinoa, amaranth, millet
Lilly Family – onions, garlic, shallots, leeks
Nuts – almonds, sesame, walnuts, coconut, sunflower seeds (and their oils and butters)
Poultry – chicken, turkey, duck, goose
Seasonings – salt, black pepper, ginger (fresh or dried), olive oil, sunflower oil, canola oil, most herbs and spices
Squash – zucchini, pumpkin, butternut squash, acorn squash, turban squash, etc.
Sweet potato

No sweeteners other than rice syrup. Rice milk is also acceptable if you can find one that contains only rice, water, and enzyme.


When reintroducting, eat two servings a day for two days. Basically, put some of the target food in two different meals everyday. You should experience nothing noticeable. The order doesn't matter, though some things must be tested in order. If an item is marked with a ★, then it should be the target food for testing.

If you feel a reaction, remove the offending food and wait about 4 days until symptoms go away and proceed to the next food. Re-test all offending foods at the end.
