Toxic Food Combinations [moved from General Topics board]

Ever since I was a little kid, my parents have told me that eating crabs and persimmons together in the same meal is lethal. I highly doubt the validity of this but the image of a slow crab-persimmon induced death has been forever etched in my subconscious.

Are there actual food combinations that are lethal/bad for you?

  1. I remember my grandmother having a taboo on fish and sweet (not buttermilk) milk. She would swear it would make you sick all night.

    1. According to my family history, one of my mom's siblings died after eating cherries and milk. Mom, of course, scoffs at the notion, but at least some of her older sisters still believe it, some 60+ years later.

      1. re: ricepad

        I think the cherries and milk myth is older than that--President Zachary Taylor died after a snack of cherries and milk in 1850. Could have been bad milk--typhoid or cholera or something like that.

        I have also heard of the fish and milk thing--my ex-husband swore that combination made him sick. Of course, he is an idiot.

        1. re: sparrowgrass

          I didn't mean that my family ORIGINATED the myth...only that some members believe it. Mom's sister did, in fact, die, and the proximal consumption of cherries and milk convinced my aunts of the connection.

          1. re: ricepad

            That's interesting, I wonder if cherry ice cream or just cherries and anything cream would be the same to them?

            Citrus and milk, mostly orange juice I NEVER have. I rather enjoy the lemon in my salad mixed with the cream sauce on my plate though.

            1. re: BamiaWruz

              One of my favourite things ever is orange juice with a big blog of vanilla ice cream in it.
              Reports of my death have been greatly exaggerated.

              1. re: BamiaWruz

                Better not eat my amazing blood orange panna cotta or lemon pudding cake?
                Imagine life without lemon cheesecake? I think not!

            2. re: sparrowgrass

              I think Taylor was likely poisoned by his 'doctors'. But yes, typhoid was widespread in Washington back then.

            3. re: ricepad

              That can't be right, there is cherry ice cream all over the place.

              1. re: ricepad

                I am horribly allergic to fresh cherries and fresh milk, when consumed within an hour or so of each other. How do I know? By observing cherries in my vomit (ew) many times as a teenager, then realizing that I always drank milk throughout the day, and then deliberately eating the combination twice (!!) and getting violently ill (from both ends) all night after both times. Sweating/chills, projectile vomiting and diarrhea for at least 12 hours, including dry heaves after the stomach was completely empty. Yikes. You would think I'd only have to try it once to figure out my toxic reaction...

                1. re: Emmarie59

                  Did you ever eat cherries by themselves to see if you had a reaction? I know quite a few people, including my kids, who have oral allergy syndrome to cherries.

                  1. re: chowser

                    Yes, many times I've over-eaten cherries with no reaction. This morning I ate around 25 cherries. What a piggie.

                  1. re: Robert Lauriston

                    Most especially durian and beer. Over ripe durian belches are best avoided if you value your sanity and your friends and family. I wanted to die the one time I had this combo, but unfortunately for the next few hours I remained alive... and suffered greatly. It's a bad day when the smell of your own burps makes your eyes water and you feel faint and nauseous.

                    1. re: JMF

                      That's hilarious! I remember to avoid that combo.

                      I think the perisimmons and crab combo is based on the old Chinese philosophy of ying and yang, that some foods are "hot" and others are "cold" and that certain combinations of these things can create "poisons" in the body. Or at least that's the only coherent explanation I was ever able to get from my parents.

                      1. re: mielimato

                        At a Shenzhen, China hotel, I saw a list of examples of what you're taking about. I wish I could recall the Chinese characters that were omnipresent in the list.

                          1. re: DeppityDawg

                            Ah yes. Though, it says "Cantonese" and lists Mandarin pinyin...

                            1. re: BuildingMyBento

                              Typical Wikipedia sloppiness… But did any of the characters ring a bell? I suspect that this vocabulary is pretty constant across the Chinese regional languages. Well, on second thought, I have no idea. But even in Shenzhen, most written Chinese would likely be in Mandarin (or it could be read equally well in Cantonese and Mandarin).

                        Dude- sounds like you should have stayed outside- in a crosswind.

                    2. the combination of crab and persimmon is very true, believe it or not. my mom just this very week had a really bad reaction and had to be hospitalized for a day. my mom never had any allergies before either. she first had persimmons then had a crab noodle soup later that night and she had a terrible rash break out all over her body. so, as crazy as it sounds, it's definitely true.

                        On Monday my wife finished up some crab and corn chowder that we had made this weekend. Last night (Tuesday) she ate a persimmon. She didn't say anything about not feeling well. On the other hand, she is still in bed- now I'm wondering if I need to go wake her up to check on her!

                      2. Raw shellfish and beer, I've heard. I always make sure to drink something else.

                          Raw oysters w/o beer? Please, say it isn't so!

                          1. re: coll

                            Guinness is a traditional accompaniment for oysters on the half shell. Beer often takes the place of sake at sushi and sashimi bars that serve raw scallops and other uncooked shellfish. Have never heard of anyone complaining of ill effects from the combination.

                                We had a local celebrity here once get pulled over for DUI and claimed it was the whiskey and oysters he had consumed, that was causing him to weave all over the road...

                                1. I was at an ice cream shop in Germany where everyone was having ice cream w/ beer on the side. I asked for water instead, the waiter stuck his tongue out at me, grimaced and said something to my German friend. My friend told me the waiter said water with ice cream would make me sick. So, beer and ice cream is fine but water will make me sick?

                                        I have that problem with fish and tomatoes--but cocktail sauce is fine, as is ketchup with salmon patties. So I'm pretty sure it's in my head.

                                        1. re: Peg

                                          Seafood or fish in a creamy sauce (like lobster newburg) makes me sick, especially when accompanied by a glass of wine. It's a shame, because it's a tasty and rather common combination. But it doesn't sit well with me at all.

                                        2. There can be some bad combinations.
                                          Ginseng can act as a blood thinner, so in combination with some other herbs/foods/medicines(aspirin) can cause bleeding.
                                          Alchohol can intensify certain properties.
                                          Most of the "bad" effects happen with raw or near raw combinations as cooking can often change the properties of the ingredients.

                                          has a lot of information on the properties of different foods.

                                          1. Emeril always cautioned against combining citrus with dairy. I don't really know why. I've made a sauce for years for veal scallipini that combines cream with mustard and lemon juice (and garlic, capers, tomatoes and olives).

                                              The sauce is probably fine, but one way to make sour milk for a cake is to mix lemon juice with milk and let it sit a few minutes.

                                                  Yeah, but I prefer using organic yoghurt. It doesn't ALWAYS do the whole job, sometimes I still have to add a little lemon juice, but it at least cuts it way way down.

                                                I made some lamb chops that involved yogurt and lemon juice (Epicurious, I think) and it was wonderful and we're fine.

                                                  Not claiming to be an expert, but I thought acids and milk could cause the solids to precipitate out, leading to chunks of material in the food? But maybe cream is protected by its fat content and the yogourt is already processed due to the fermentation process? Or if you add cream and acid to a sauce, you can ad them in a certain order to avoid the curdling?Any real experts out there? This is a good question...

                                                  another toxic combination: Korean salted pollack (fish) roe and chocolate. This is what happens when you eat a Korean meal and follow it up with a Western dessert. Fishy doesn't go so well with cocoa. To put it another way, there ain't going to be a Vosges Mo fish roe chocolate bar soon. Nor should Koreans come out with chocolate covered dried squid (although I have a sneaking suspicion that it has been tried, I wouldn't put it past my tribe)

                                                    Some of the flavor combos Koreans have come up with probably should go in the toxic category.
                                                    I believe I did see a short lived chocolate covered shrimp chip while I lived in Korea.

                                                              There is a ratio of how much lemon any milk or cream will handle before curdling. I posted my all-time-ever favorite cocktail (pink lady in a version that is sometimes called a pink rose) in another thread that is drop-dead fantastic, but has a really wicked kick. Tastes so innocently good I'm very careful who I serve it to. It contains gin, an egg white, half and half, grenadine and fresh lemon juice, but mess up on the ratios and you have a martini glassful of pink cottage cheese! blech! However, I don't have any experience trying to mix Bailey's Irish Cream with anything more than Bailey's Irish Cream! Some things just come across to me as trying to French fry beluga caviar. Why?

Has Baileys, dark rum, banana liqueur, fresh banana and pina colada mix in equal amounts, with lots of ice: can add a floater of dark rum on top. Talk about a wicked kick, after you think you just drank a milkshake!

                                                                I know this is many years old, but I went looking for this tonight because…

                                                                Around 11:30 this AM I got a latte from Starbucks, non fat milk. Didn't get to drink it for quite awhile, because I wanted it with my breakfast I had yet to make. Breakfast was cheese toast (melted Dubliner on a very dense, nutty European bread), super pulpy orange juice (which I very rarely drink) and the now lukewarm latte. Started feeling a bit crappy about 30 minutes later, almost as if I had eaten too much (although I only had one piece of toast), and it just got worse throughout the day. Around 3 I took the dogs out, and had to cut our walk short because I felt so achy and tired and nauseas. Couldn't get off the couch for about three hours, and the only reason I did is because I was freezing (it was in the '70's in SoCal) and thought a bath would help. Obviously by this time I'm thinking flu. Had a scalding bath, but could not get warm. Finally got out, and barely had the energy to throw on sweats and a sweatshirt before I fell back on the couch (still freezing). After another hour of writhing my aching legs and groaning, I made myself puke (sorry--TMI) and ended up violently projectiling what smelled like (again, sorry) very curdled milk. It's now about 3 hours later, and I'm just starting to feel pretty normal-a bit hungry, even. The only thing I can think of is the warm milk/ OJ combo. Also, my stomach was very bloated all day- which means it's probably dairy related? Anyway, it's never happened before, but then, if I make coffee at home, I usually use CoffeeMate creamer, which I think is non-dairy. Not sure why it happened, but it is a combo I will be staying away from for the rest of my life!!! PS-I soaked a washcloth in cold water and a few drops of lavender oil-it's really helped get the old-baby-puke smell out of my nostrils :)

                                                                1. re: schrutefarms

                                                                  glad you're feeling better.

                                                                  1. re: schrutefarms

                                                                    i drink my coffee with half and half even hours after it has reached room temp. but then i'm "ironstomach" woman. (usually ;-).

                                                                    1. re: alkapal

I'm pretty sensitive to coffee - I can only drink about 1/4 of a cup at a time, or I get strangely feverish/cold. So I either pour myself a tiny cup, or I have a regular sized cup that I let sit around until lunchtime. Never bothered me a bit!

                                                                      1. re: khh1138

Also, I've had cereal with milk and a glass of OJ for breakfast and was never bothered. I think Starbucks gave me some rancid milk. Either that or didn't wash their hands. That seems to be the only real logical explaination.

                                                                        1. re: schrutefarms

                                                                              1. re: maria lorraine

I have tons of friends coming down with it and it's decimating attendance in some classrooms. I had it myself 2 weeks ago and my husband had it last weekend. Intense cramping, diarrhea, nausea, vomiting, fatigue. I find it extremely unlikely that all of these people are coming down with undiagnosed food poisoning.

                                                                                1. re: Chris VR

                                                                                  1. re: Chris VR

                                                                                  3. re: Chris VR

                                                                                      1. re: pikawicca

                                                                                        1. re: maria lorraine

                                                                                          She said she's been seeing a dozen or more people a day recently, all with the same symptoms.

                                                                                          Since very few of them eat in the same places, it's highly unlikely to be food poisoning -- her patients range from toddlers to retirees.

                                                                                          It just might be what she said it is.

                                                                                            As well as touching surfaces contaminated with the virus, and being exposed to infected persons.

                                                                                            1. re: maria lorraine

                                                                                              I'm pretty sure if it were norovirus, it would be called norovirus and not a "24-hour bug that's going around".

                                                                                              How is it you can acquire enough information to diagnose patients whom you've not examined, and whose history you don't know?

                                                                                              1. re: sunshine842

                                                                                                Norovirus usually takes longer to resolve than 24 hours (the resolution here was about 5 hours, too quick for noro, and after vomiting/elimination). With norovirus, also, the onset is .5 to 7 days after exposure.

                                                                                                I've just checked with the medical folks around me about norovirus, and with some other folks versed in food poisoning onset and resolution, and I'm standing by what I have written.

                                                                                                True, none of us can diagnose from a distance.

Here's what makes me think it might be a poisoning of some sort--right after I threw up, all the body aches/fever/freezing cold feeling went away, although I was still nauseas the next day (but I don't think I got it all out). Usually when I've had a sort of flu/virus thing, the puking comes along for the ride. This time, it was the aching/fever etc that was hanging on the throw-ups coat tails. As soon as the contents of the stomach were eleminated, the rest went away too. And the thought of having a latte makes me shudder! (Although I had a hot cocoa tonight and it was fine).

                                                                                                  1. re: schrutefarms

Both times the symptoms went on for (torturous) hours. I am no sort of medical professional, that's just been my experience.

                                                                                                2. re: sunshine842

I'm just a snot-nosed resident but not sure why Maria Lorraine is insisting that only food poisoning is short-lived. Many stomach viruses can be symptomatically short lived. Perhaps they infected days before symptoms but to the sufferer it can be a 24-36 hour illness and not be food poisoning. Norivirus is not the only cause of non food-borne gastroenteritis.

                                                                                                  1. re: fldhkybnva

                                                                                                    I'm quite familiar with food-borne illnesses, safety, precaution, etc.

When I make paneer (an Indian soft cheese), it involves boiling a gallon of whole milk and then throwing in some lemon juice.

                                                                              1. re: goodhealthgourmet

I tried to connect to the "I can't poop!" link on Youtube but unfortunately they had removed their video. Good thing, I might have popped a gut laughing... Not quite what they were intending with their whole Colonic Cleansing message.

Among the forbidden pairs: acid + starch. My inner italian laughed every time I scooped some tomato sauce over a nice plate of spaghetti. Carbonara drove her absolutely bonkers ("oh my god! you can't mix eggs with cheese! and protein and grain together! no!")

                                                                                  I think that was when I decided to never use scientific sounding terms I didn't really understand ("protein", "carbohydrate", "lactose") in place of actual food words because that seemed to lead to deep confusion.

                                                                                  1. re: Chuckles the Clone

                                                                                      "If that is the case, you may well wonder, then why does the stomach have no trouble handling foods that naturally contain both protein and starch, such as whole grains?

                                                                                      As Dr. Shelton points out, "There is a great difference between the digestion of a food, however complex its composition, and the digestion of a mixture of different foods."

                                                                                      To a single article of food that is a starch-protein combination, the body can easily adjust its juices, both as to strength and timing, to the digestive requirements of the food. But when two foods are eaten with different, even opposite, digestive needs, this precise adjustment of juices to requirements becomes impossible."

                                                                                      I love it . My stomach is smart enough to figure out the difference between a single type of food vs. 2 different types of food. How can we NOT believe?????

GFJ + Xanax (alprazolam) will actually prevent the body from metabolizing the Xanax, thus making it feel considerably stronger and make it last longer. This could be undesirable or even dangerous for some people.

When their doctor put them on Lipitor, they asked him about the sign on the side that said they couldn't eat grapefruit. He said that it probably wouldn't hurt them since the daily grapefruit consumption predated the Lipitor. So they continue to take their Lipitor and eat their grapefruit, and their cholesterol counts are where they're supposed to be now. YMMV, however, and folks should obviously check with their own doctors.

                                                                                            1. re: revsharkie

It can be potentially dangerous, especially the Lipitor (or other cholesterol lowering meds) and grapefruit, either whole fruit or juice. Apparently the grapefruit actually raises the concentration of the drug in your system (does not block the medication, as mentioned above). My grandfather ate a grapefruit every morning and several months after starting Lipitor was diagnosed with painful and debilitating peripheral neuropathy - basically the nerves in his hands and feet were permanently damaged and he could no longer walk. Please let your folks know. There's lots more info out there on this awful side effect.

You can easily check by looking at the back of one of those thin yearly Chinese Almanac-type book. While most combo they list (with drawings of the items, so you don't really have to read Chinese to get it) are not lethal, they always list the antidote for the condition. I think about 70% of the time, green mung bean soup is the antidote. This is especially so if the condition is some sort of skin rash.

                                                                                              As for the validity? You all can laugh all you want. Do stop to consider that perhaps in the olden time various food had more distinct properties than they do today. As a kid I was traumatized when my face broke out with boils after eating crab and pumpkin (or persimmon?), not even in the same meal, but probably in the same day. The thing that stuck out in my mind was the stupid things that kids do to scare themselves... there were only a couple of them left to heal, as they're scabbing, I kept staring at the one on my nose...me with a mirror in my hand...focussing so hard on this ugly ugly boil...quickly looking away, and then inevitably unable to NOT look, I look again, and back and forth, and of course, eventually got so disgusted that I started yelling and crying...
                                                                                              ah well, I was maybe 5, 6 years old...but it DID happen!

                                                                                              1. Persimmons generally can be dangerous if they aren't ripe. Unripe persimmons, especially some varieties, contain lots and lots of tannin that can bind with protein in your stomach and create a bezoar (google persimmon bezoar), which is an indigestible mass that sticks around in your stomach for a while. I don't know if crab has anything unique that exacerbates this, but it is high in protein so it would certainly contribute.

I seem to remember a similar do not drink milk with stuff like lobster rule too........when i was growing up.

I'm not sure of the validity of this, but I've heard that one apple core can contain enough HCN to possibly harm a child. Probably a good idea to avoid eating them.

                                                                                                      1. re: vorpal

So they are only dangerous if you break the seeds covering. The numbers I read said that it takes about 100g (approx 1/2 cup) of seeds with the skins broken to make a 150 lb person ill. That's a lot of seeds!!

                                                                                                        1. re: Sooeygun

He supposedly died. But, the cyanide has such a bitter taste, I'm surprised anyone could eat that many.

                                                                                                    2. You must be Korean because I vaguely remember my mom telling me this as well. A quick google search led me to this:

                                                                                                      http://www.zagalchi.co.kr/zagal/eza-s...

                                                                                                      People on this board seem to be ridiculing this food combining guy because he's saying things that are not based on scientific claims. I haven't seen his website, but I do know a lot of people who have had an easier time with digestion once they did incorporate food combining principles. It's probably not for everybody. But in my experience those who have serious problems with digestion do find some benefit. I'm not sure what terminology he's using to describe it -- but basically food combining principles say if you eat meat, dairy or legumes you should combine it with green low-carb vegetables as opposed to complex starches (eg. grains) for more efficient digestion. I don't think I could do this because this means I would have to give up dumplings.

                                                                                                      I feel that before completely dismissing something to try it for oneself. When I was younger I laughed at so many things because it wasn't scientific (I was involved with science and mathematic research) and sounded ridiculous. However, as I get older and experience new things, I see the wisdom in a lot of these claims. And I realize how presumptive I was in the past. It pays to keep an open mind. So don't beat it until you try it.

Too many rules and like I already said, it takes the JOY out of eating. By all means you go ahead and try it and let us know how it goes. If I was to try to follow all of his ridiculous rules I would probably be eating every hour. Which would wear down the enamel on my teeth because my mouth would be so acidic. Etc. Etc. Nope I still think its the stupidest thing I ever heard of.

Drinking water with your pork would dilute the gastric juices, impeding digestion.

                                                                                                                      2. I quickly browsed through the other posts, so if I repeat something already mentioned, I apologize ahead of time.

She even had what we called the "fortune telling book" which listed all the "dangereous" food combinations. Right there in black and white characters was the warning against combining tempura and watermelon in the same sitting. Or maybe she just didn't want to cut up the melon. Hmm.

                                                                                                                            On a funnier note, I knew someone who took the "no acid/milk" thing literally, until the point when I noted that by that defintion, and ice cream soda or root beer float was impossible, since even if you found a soda that was citric acid free (an practically all types have citric acid in them somewhere) your still left with the fact that carbonated water is istelf an acid (H2O+CO2=H2CO3(carbonic acid) and is more than capable of curding milk on its own (I know I actually tried it once) .

In addition, the crab and persimmon all belong to the cold and cool things , at the same time can easily cause to uncomfortable if take it excessively .

The idea is that drinking cold water, interacting with the cheese in your stomach, creates a ball of cheese, making for a very unpleasant digestion. I had alwyas heard this ("you must drink wine, my dear") and my step-son confirms that he had a terrible experince in Switzerland chowing fondue and guzzleing water.

Try to follow these rules and something along the line of the USDA reccomended daily servings, and youd pretty much have to structure your diet so that youd have to be eating all of your daily servings of each category at one sitting (since I'm failry sure, based on the terms this person is using, that one has to wait until the meal you just ate is fully digested before you can move onto the next one) which probably isn't good for you. In fact, given some of the intereactions, you'd probably have to designate specific days for every nutrient (eat only meat on monday, only starches on tuesday, only fruit on wed, etc and have to practically gorge yourself on that days nutrient (Imagine trying to to eat a weeks worth of carbos in one day) to compensate. which can't be good for you. They also deserve an "F" in basic nutrition, since some of the foods they mentioned would tecnically be completely inedible under thier rules. For example the person says that you can't eat beans or peas with carbo's becuse protein stimulates you acid, and carbo's your alkaline. well if that were true then you couln't eat beans etc. at all becuse they are in and of themselves BOTH legumes contain both proteins AND starch as does practically every other seed (some seeds store more of thier energy as fats some most as starch but pretty much all seeds have a bit of both)

According to them, the proteins and starches in legumes are in fact very difficult for the human body to digest as is or on thier own. supposedly however all of those spices (ginger, coriander, chile etc.) that are added to the legume dishes (espicially in the case of Indain "dal" dishes serve to make all of the legume nutrients avaliable. They are also supposed to provide the body with the enzymes needed to digest raffinose (a common sugar in legumes and some other vegatbles (like cabbage) and supposedly the reason this foods are so gas producing (we can't digest it, but the bacteria in our guts can, by fermentation) which is why people from cultures whose diets are legume heavy are not all constantly passing gas. anyone know if all of this is true?
