Beans! Beans! The Magical Fruit?

Posted October 13, 2008 12:01 AM by Jaxy

I never really thought there was any truth to the phrase 'Beans! Beans! The magical fruit; the more you eat; the more you toot!' After all, beans are a vegetable, right? Then I took a quiz from MIStupid.com to try to tell if various plants are fruits or vegetables. I learned that while many foods may be harvested like vegetables, they are actually classified as fruits.

I was brought up thinking that the fresh produce grown in our garden were vegetables - plants like cucumbers, pumpkins, peppers, lettuce, potatoes and tomatoes. Later, it was learned that tomatoes were considered a fruit. This new classification didn't change how we gathered tomatoes and planted them in the (mostly) vegetable garden. Now, I have been reading more and more that a lot of the foods we planted in our so called 'vegetable garden' are really fruits. So what gives?

A lot of websites have definitions for fruits and vegetables. Fruits are defined as the maturing ovary of flowering plants. This makes sense. There are flowers on apple trees right before tiny round apples appear. It never dawned on me, however, that - like apple trees in the Spring - peppers, cucumbers and pumpkins all have flowers before their associated crop starts to grow. Now you know what a fruit really is.

The basic definition of a vegetable is a plant where you eat anything besides the reproductive organs. Some examples of edible plant parts are the stalk (celery), bulbs (garlic), leaves (lettuce), and roots (carrot). So as long as you aren't eating the flesh of a mature ovary in your garden, you are eating a vegetable. Not very appetizing, huh?

By understanding these definitions of fruits and vegetables, it is easy to see why some of what we thought were vegetables are really fruits. Historically, fruits have been known for their sweet, pungent tastes and aromas. But now there are new fruits in town. And these new fruits are found in your garden not on your trees.

An interesting theme......could I humbly ask Jaxy to investigate 'Berries' at some time ? A recent viewing of the BBC TV programme QI had some interesting stuff about the definition of 'Berry'. As Cnpower says, it tastes nice whatever you call it (Shaeksperean mode is off, otherwise I'd have gone for the obvious 'a rose by any other name.......' quote).

Living in UK climes, I've never tasted the Durian. Do any members have direct experience, and does it really taste like custard one you get over the smell ?

Berry interesting topic! Durian - smells like the near-rhyming carrion - has the approximate texture of custard, but not the precise flavor. And of course, that depends on the custard itself. Flan is usually a caramel flavor, while lemon custard is citrus. Obviously, the flavor additives are going to make a difference.

I will definitely have to look into 'Berries'. It sounds very interesting, as I am an avid fan of native berries (blackberries, strawberries, etc.). I will keep you posted!

They are and they aren't the ovary either. Beans are the actual seed.

Aha! Biology! Yes, they are legumes, which is like saying wheat is a grass. True, but not germane. And yes, beans and peas are seeds, but the pods containing them (string beans, peapods) are technically a fruit. Or perhaps more to your taste (so to speak) a "fruiting body", since the seeds are contained within them, much as the seeds of an apple or an orange are contained in their respective fruits. Nuts are similar, in that the contents of the shell is the seed, and the shell is essentially the pod. Vegetables consist of the "vegetative body" of the plant, such as roots, stems, and leaves.

But potatoes, onions and cattails, aren't they considered tubers?

Yes they are, and tubers are in the definition of the vegetable. As long as no part of the reproductive system is being eaten (seeds and otherwise), they are considered veggies.

That raises an interesting question - what do people crave in the morning ? With me it's the coffee + a cigarrette. Some poor souls like a cup of tea, and others salivate at toast and marmalade. Maybe STLEngineer could upgrade his previous thread about 'What was your evening meal". Boiled (chicken) eggs are nice.

Why, as a matter of fact, raw coffee beans when picked are called "cherries". Wouldn't think a pie made from 'em would be as good as the cuppa they provide to wash down a pie, tho'! And that ain't tellin' ya no pork pies, either...

All these terms are getting terribly confusing ! A cherry contains a single stone (?), so an Avocado is a cherry - I wonder if that makes it the biggest cherry, or at least the cherry with the biggest stone. To add to my confusion, drupes get subdivided. Ive just discovered the etymology of avocado - They'll never taste the same again !

And don't forget the drupelets! Did you read this part about the avocado? A very strange fruit indeed!

The avocado is unusual in that the timing of the male and female flower phases differs among cultivars. There are two flowering types, "A" and "B". "A" cultivar flowers open as female on the morning of the first day and close in late morning or early afternoon. Then they open as male in the afternoon of the second day. "B" varieties open as female on the afternoon of the first day, close in late afternoon and reopen as male the following morning.

Nothing like trying to classify food to get you really confused. Next time I eat something I can't help but wonder, 'is this a fruit or a veggie, berry or a fake fruit or even an aggregate fruit, is it picked as a cherry...?' I don't think I will enjoy my produce as much anymore

But on the upside, I already knew avocado's were weird, so this isn't a surprise to me...

Farfel is new on me.....I think The Herbs must have been stop-motion. I'm pretty sure we also invented claymation with 'Morph' as first introduced on Vision On. Tony Hart's show was pure genius. Another one (more recent) called Art Attack was excellent. Sadly, I think one of the main presenters killed himself. Rotten shame - he had a huge talent for creating pictures out of all sorts of random items (eg spreading clothing across a floor to create a picture). Very 'Rolf' - creating a large picture that during initial creation made no sense. People like those probably inspired more people to try art than any so called 'famous' artists. I haven't checked, but I'm sure much of their work will be found on the web. The artist Banksy has recently hit the States - he's something of a cult hero in the UK ; a sort of Robin Hood of art. Well worth looking up.

Have I been wrong all these 80+ years?

I learned the rhyme as MUSICAL......not magical...to me it makes more sense with "toot".

I'm not obviously qualified to answer whether you've been wrong for 80+ years or not. Could be so, doesn't have to be so. However, I too learned it as "the musical fruit" vice "magical" so in that, you seem to be correct.

I learned it as magical. Perhaps it is magic that it makes you "toot" consistently?

I suppose kids learn it differently.

You could very well be right, but I learned it as magical, so that is the way I have remembered the rhyme.

At one time in the U.S., various vegetables were categorized as "fruits" because of a tariff on vegetables. There was no tariff on fruits.

What a fruity practice! Lettuce rejoice that we have progressed beyond such...we haven't? Oh, well never mind then...

You heard about the down-on-his-luck hitman named Artie didn't you? Guy hired him to kill his wife for a buck. With such a thin profit margin, he decided the best way to hit her was to strangle her. He followed her when she went shopping, and caught her in the produce department of the grocery store. Unfortunately, when he did the dirty deed, the produce manager walked out of the back room and saw the hit go down. In order to not leave witnesses, Artie strangled him, too. However, the police caught him because the video surveillance cameras also saw the whole thing. The next day, the newspaper headline read...

...are you ready for this?

"Artie Chokes Two For a Dollar at A&P"
