I never eat the skin of a cucumber - it CANNOT be digested - yuk! I limit raw spinach to baby spinich added to salads along with a variety of lettuce. Never raw root vegegables or eggplant. And a far as other posts regarding digestion of greens, that is what our Appendix was once used for - to aid in the digestion of grasses and the like - but, since "cooking" came into existance, the use of this organ declined, now it is a "useless" organ. Just fyi.

Really fresh, at their peak Brussels sprouts are fine raw, and in fact can be quite good. I've had them in salads many times. Here's a recipe for you (though I don't usually use much of a recipe): http://www.101cookbooks.com/archives/...

Red kidney beans (The toxin Phytohaemagglutnin is strong enough that just 4 or 5 beans can start nausea, vomiting, and abdominal pain.Take note preschool art teachers!), and Buckwheat greens ( [I have also heard sprouts in high amounts] contain fagopyrin, which causes skin to become hypersensitive to sunlight. Fagopyrism also causes some people to itch, feel fuzzy, numb, tingly, or dizzy and skin painful when exposed to cold or hot).

I guess this goes into the raw potato issue, but while I'm completely ok with eating chopped raw onion or rings of raw onion on a sandwich or in a salad - I know some people who eat raw white onions like apples.

ackee, technically a fruit...not only must it be cooked but it has to be of pefect ripeness (you can't pick them, you have to wait for them to fall off the tree BUT they can't be overripe or its poisonous as well).
With potatoes, I think it's just the green part of a raw one (if found) that is toxic.›1 Reply-
re: epicura
from "the inquisitev cooks"
The greenish hue is actually chlorophyll, but it is also an indicator that an alkaloid, called solanine, may be present under the skin of the potato. Solanine develops in potatoes when they are stored in the presence of light (which also encourages chlorophyll formation) and either at very cold or quite warm temperatures. It is toxic, however it would take a very large number of green potatoes to make you ill.

I wouldn't eat large eggplant raw, but I know "Thai" eggplant, those little round, green and white balls, are eaten raw with laap sometimes.
However, I must admit, that isn't to my taste. My parents like it like that. I prefer Thai eggplant in my red curry stir fry. It's good. :)

"Raw spinach can cause calcium deficiency if you eat lots of it and your diet is low in calcium. Apparently, spinach shouldn't be eaten by folks w/ arthritis or kidney problems, either, as the oxalic acid can exacerbate these conditions."
Raw spinach will not cause calcium deficiency. Spinach contains some calcium, but the oxalic acid in spinach binds with the calcium in spinach and this oxalic acid-calcium complex is not absorbable. However, the oxalic acid in spinach does not tie up any other co-ingested calcium--that is, calcium in your digestive tract but not in the spinach.
Also, the concern of oxalic acid and kidney problems really only applies to people who are "stone formers". Most kidney stones are made of calcium oxalate--an oxalic acid-calcium complex. Oxalic acid (which, by the way, is a breakdown product of vitamin C) does not cause any other kidney problems that I know of.

re: ATS
Calcium is calcium and the oxalic acid binds up calcium in whatever it is that you consumed. It can also tie up iron, magnesium and potassium. A quick reference (go ahead and complain about my cheap source, Wikipedia)
http://en.wikipedia.org/wiki/Oxalic_acid
Apparently, though, and in your defense, it takes a LOT of oxalate containing foods to cause troubles and, in my defense, I said it's only a problem in a diet that is low in calcium.

re: ATS
Having once had a kidney stone that was made of oxalic acid and having subsequently looked up oxalic acid and learned that it's in spinach, I quickly gave up spinach. But now that I am in touch with experts I'd like to ask about other greens like collards, kale, mustard, turnips. Are they also sources of oxalic acid? Many thanks for any info.

re: JMF
Yep. Raw spinach can cause calcium deficiency if you eat lots of it and your diet is low in calcium. Apparently, spinach shouldn't be eaten by folks w/ arthritis or kidney problems, either, as the oxalic acid can exacerbate these conditions. And I don't know how much oxalic acid is destroyed by cooking. Is there a chemist in the house? (IUPAC fans: ethanedioic acid)
I've also heard that the iron in cooked spinach is more readily usable than that in raw spinach. Don't have a source to back the spinach/ iron claim up, though.

re: JMF
I keep trying to research this question whenever it comes up and always have a hard time finding scientifically based source (as opposed to popular articles with everyone repeating the same factoids). Here's the best I've come up with this time:
http://www.whfoods.com/genpage.php?tn...
The upshot seems to be that if you have a medical condition where you should avoid oxalates, definitely avoid spinach, raw or cooked. But it isn't a worry for most of us.
I found this statement most intriguing:
"Repeated food chemistry studies have shown no statistically significant lowering of oxalate content following the blanching or boiling of green leafy vegetables. A lowering of oxalate content by about 5-15% is the most you should expect when cooking a high-oxalate food. "
-
re: Karen_Schaffer
Yeah. I am slightly skeptical that cooking destroys oxalic acid. You'd definitely have to get it to a temp above that at which water boils because it is a double carboxylic acid and you have to bust up lots of H bonds to break it down. I'd imagine that most folks w/ a medical condition of concern are aware of whether or not they can consume spinach raw or cooked.

re: JMF
I don't know, I see more on the web recommending raw spinach for its health benefits. I guess if you have problems with oxalic acid it shouldn't be eaten. But there are a gazillion recipes using raw spinach. I enjoyed the spinach salad with hot bacon dressing at Marie Callendars for many years.

We occasionally use a juicer to make carrot juice.
One time we got some organic young beets from someone's garden and made raw beet juice. It was so pretty.One sip of it -- and my throat closed up as though I had swallowed shards of glass. Never again. And I am not allergic to any food.
Some mixed vegetable juices have small amounts of beet juice in them, but that may be cooked juice. I love cooked beets and can eat large quantities of them. I have tasted small slivers of raw beets, thinly sliced, with no ill effect. Maybe the juice has the causative factor, maybe the fibers in the raw fruit have a protective effect.

>>> One sip of it -- and my throat closed up as though I had swallowed shards of glass. Never again. And I am not allergic to any food.
Well, you could be alergic to beet juice. Raw beet juice is recommended for helping with kidney problems and arthritis.
Mexicans drink a beverage called a vamipira which is a mix of vegetables and raw beets. I had this and didn't have any problems. I watched them put a peeled uncooked beet in the juice. Didn't have any problems with it.
Could be also be a reaction to whatever it was your neighbor was using to grow the beet, however organic. When I was a teen, we took a trip to Amish country ... and ate at a place where everthing was natural food ... no own else was bothered, but I broke out in a rash and my legs swelled up. So something was in all that natural food that I reacted to.

re: rworange
And I've used raw beet juice to make sorbet. It's actually pretty tasty.
But I agree with Morton that you don't get the full nutritional value of many vegetables if you don't cook them. This even applies to vegetables commonly eaten raw, like carrots. The cooking helps break down the cell walls so the nutrients can be absorbed.
Personally, I'm not big on most raw veggies -- very few aren't improved by at least blanching.

re: Ruth Lafler
The raw food movement believes just the opposite even though I have never seen any scientific evidence supporting their beliefs. If anybody has some evidence for them beyond wild conjecture, please cite it.
Blanching to destroy the allegedly valuable enzymes is a technique to stop internal deterioration of many foods and is a necessity when freezing most vegetables.

re: Eldon Kreider
My wife wrote a research paper on anti-oxidants in various grape products. She found that some anti-oxidants were lost in the winemaking, juicing, or sun drying processes. But others become more concentrated & bio-available.
Based on all the journals she read during the study... she concluded as a rule of thumb (whenever viable)... we should eat a combination of processed (cooked) & raw foods for optimal nutrition. Another way to look at it... we have been consuming both cooked & raw produce... ever since the first classifiable Homo Sapiens... and basically we evolved to flourish in that environment.
It should be noted that the oldest civilizations all have codes / rules that foment a balance of cooked to raw foods (typically the proportion of cooked is higher than raw)... this is true in Persian, Mexican, Chinese, Ethiopian & other very old cuisines.

You can also make a salad of raw beets. The one I do is either from South India or Sri Lanka (I'm not sure, to tell the truth- I'm just copying what I've had served to me) and the raw beets are shredded in a box grater. Add sliced onion, chiles, herbs and lemon juice and voila, a very tasty accompaniment that is somehow more than the sum of its parts.

I would say bigger leaves of kale or mustard greens would be a bit tough on the digestion. Eggplant of course. Artichokes are pretty bitter raw but I have had a salad of paper thin shaved hearts that was to die for.
Rhubarb needs to be cooked because of the oxalic acid in it.
It seems sweet potatoes, chayote and okra would need to be cooked, but I may be wrong on those.

Rhubarb leaves and roots contain oxalic acid. The stems don't and are delicious raw. Paula Wolfert's *The Slow Mediterranean Kitchen* has a recipe for a salad of raw rhubarb, cucumber, arugula and mint that is a knockout with salmon poached in olive oil.

re: ipsedixit
Good point. I guess it depends on whether you're talking to a botanist or a chef.
It's definitely a stretch of the word, but the meaning of vegetable is extremely ambigious (do vegetables include fruit? Do they only include savory fruit? Do they include nuts, seeds and legumes?) and I prefer a broad definition.
-
-
re: Thefoodgenius
Just because you think you know the meaning of a word doesn't make it unambiguous.
The dictionary definition of vegetable includes all parts of an edible plant. So according to Webster, an apple is a vegetable. But in common culinary usage, vegetables are distinct from fruits. And where the line falls between the two is sufficiently unclear that the US Supreme Court has become involved in making that distinction. (Nix v. Hedden (1893) 149 U.S. 304 [tomatoes, though botanically fruit, are vegetables for culinary purposes and subject to taxation as such]).
If that's not ambiguity, I don't know what ambiguity is.

re: Morton the Mousse
To clarify: these foods should be cooked to fully utlize nutritional content, to avoid small quanities of naturally occuring toxins, and for taste reasons.
Raw olives contain an extremely bitter substance called oleuropein. They are inedible to all but the most stubborn raw foodists. Brining olives removes the oleuropein, as does pressing them into oil.
Raw eggplant contains the toxin solamine. Most of the nightshade family contain toxins in at least one part of the plan, but eggplants are noted for a high toxin quantity in the fruit. Solamine wont kill you, but it wont help you either. More importantly, eggplant should be salted, pressed and cooked in order to obtain a desirable flavor and texture.
Many raw mushrooms contain trace amounts of toxins that break down when cooked. Of course it depends on the variety of mushrooms and those standard, supermaket whitecaps are fairly benign. Again, cooking is also desirable for taste reasons.
Raw high fiber greens such as spinach and kale contain few bioavailable nutrients. The complex fibers are simply too difficult for your digestive system to break down unless you chew each bite 50 times. It's not going to hurt you, but you're not going to benefit from all of the naturally occuring nutrients. Greens also taste better cooked, especially in a bit of pork fat.
Cooking food was one of the most crucial developments in human evolution as it allowed us to eliminate naturally occuring toxins and break down nutrients so they are easier to absorb. Why some raw foodists feel the need to transcend out physiology is beyond me.

re: chocolatetartguy
The raw food movement is so fatally flawed I don't even know where to begin. Yes, in this fat-filled country it's nice to sit down to a plate of raw, fat free, additive free food once in awhile. But to say that raw>cooked all the time is ludicrous.
Taro causes throat itching if consumed raw, and can sometimes cause more severe reactions. If you've ever tried to peel a taro root without wearing gloves, you'll have noticed the skin on your arms turns very red and itchy. Imagine that in your throat.
Soy beans have small amounts of toxins unless processed.
-
re: Pei
You might want to learn more about raw foods and raw recipes before making such a denigrating comment. I have never, for example, seen a raw food recipe that includes taro root, nor soy beans. By the way, soy has a terribly high oxalate content and is best avoided altogether.
Often with raw recipes sprouting is used to increase nutrition and bio-availability.
As for kale--if I feel low energy or unwell, a kale salad with sprouts is like a miracle. And chewing is quite important. One should chew all their food thoroughly, not just leafy greens.
You have to know how to make these foods yummy and when to use sprouting, soaking, or the dehydrator. The raw food movement is nothing like the idea people have of sitting down to a bunch of uncooked veggies.

re: Morton the Mousse
I eat raw white button mushrooms, never considered eating the other types raw. Even then, I'll never forget a tv show that had someone who grew mushrooms commercially and explained the process.
For some reason he was asked if he ate the mushrooms raw. The look on that man's face haunts me to this day ... it was sort of a 'are you out of your mind' look ... he paused and just said sometimes he ate them cooked, but never raw. I think his reasons had more to do with fertiilier though.

re: rworange
White button mushrooms were (and probably still are) often grown in a mixture of straw and horse manure that has been composted. Somebody who has been composting tons of this stuff and putting it in his mushroom beds might develop an aversion to eating the product raw even though the heat of composting kills most pathogens.
-
re: rworange
Cultivated button mushrooms are generally raised in a compost made from oat hay straw and horse poop trucked in from horse farms, racetracks, large stables. It is mechanically and thoroughly composted (taken to a minimum 160 degrees) while it composts and breaks down into, well, that well-known garden soil supplement, Mushroom Compost.
It has to be benign before being innoculated with button mushroom spores, or too many wild fungus inhibit the growth of the cash crop. There should be no human-harmful bacteria surviving in compost ready for mushroom growing, otherwise wouldn't packages be labeled with food-handling precaution statements as are meats?
When the wild spores begin to invade the mushroom house, the used compost is sold to the garden supply industry and a new batch is loaded into the houses.
I'm not a mushroom grower or a scientist, just a lifelong home gardener who has been around mushroom compost and mushroom farms a lot.

re: Morton the Mousse
Eggplant does not need to be salted and pressed unless it is too mature, stale or is going to be fried. We never salt the eggplant we grow, but then it is goes into the compost bin if it gets as mature as the commercial stuff and is cooked the same day or day after picking. There is no bitterness with either Orient Express or Rosa Bianca, the two cultivars we are growing this year.
I can't see eating eggplant raw, though. We cook a lot of the surplus lightly, usually with tomato and garlic or onion and then freeze.

re: Morton the Mousse
Oh wow, I just found this page and it is really unfortunate that this person Morton the Mousse is probably gone - because his biochemistry education is AWFUL.
First off, the compound is solanine - not solamine.
Secondly, solanine is in more than just eggplant - it is also in potatoes and unripe tomatoes. However, I think that if I were to decide to eat a starchy vegetable like a potato, I would take the low solanine concentrations in an uncooked potato anyday over the acrylamide content in cooked potato products.
Thirdly, where exactly do you get off talking about how raw leafy greens contain few bioavailable nutrients? about 75% of all the vitamins in raw leafy greens are denatured and become unusuable when exposed to that amount of heat and almost 100% of all the phytonutrients are destroyed by heat as well.
Fourthly, concerning your point about chewing eat bite 50 times, it is already well known that you can only ever get as much nutrition out of your diet if you chew your food, especially your greens, into a fine paste/poultice/liquid before swallowing. This is the whole reason for making green smoothies - all of the nutrition of green leafy vegetables with the chewing already done for you.
So i could go on and on about your argument's fallacies and your lack of biochemical education but I honestly can't handle any more of it - it takes too much time to type it all out. If you have any specific nutritional biochemistry questions that I can clear up for you in the future, feel free to respond to this post.

re: Morton the Mousse
hey sorry to bother you but i don't see how you can't get the nutrients from spinach? i mean yes MOST green leafy vegetables have complex fibres of starch and cellulose, and cellulose cannot be broken down through digestion because of the hydrogen bonding. but it can be broken apart by physical processes such as chewing?
and how do the complex fibres stop you from getting nutrients?
oh and how does cooking fix this issue?????
