To not understand the puréed fruit thing?

[DeadGood]

So whole fruit is ok. Mashed fruit is ok. But puréed fruit is not.

Why? I've read something about sugars being released but it makes no sense to me.

[Tarla]

The way I understand it is that it's to do with density. So you could juice/puree half a dozen peaches and drink them down but you'd struggle to eat six whole peaches as you'd be full after two, maybe three at most.

But, having said that, everything in moderation is key and a bowl of apple puree is still healthier than a bowl of Ben and Jerry's!

[DeadGood]

Really? It's just about quantity?

So what's the "sugar stored in cell walls pseudoscience stuff?

[mikado1]

By pursuing you are voiding the fruit of its fibre (and vitamins?!) and reducing it to pure sugar.

[ItsAllGoingToBeFine]

How?

To me pureeing would involve taking fruit and whizzing it up. No difference in vitamins as no heating, no difference in fibre as all fruit is still there just in a different format.

[Sugarcoma]

When you whizz it up you breakdown the fibre.

[BarbaraofSeville]

Is whizzing really that different to chewing though?

Isn't it just that purees and smoothies make it easier to consume larger quantities and hence more calories?

But then people never make these accusations about soup. You can eat all the vegetable soup you like without any suggestion that it doesn't count as vegetables or is unhealthy.

[DeadGood]

Mikado1 you are kind of answering my question with my own question.

How does puréeing fruit reduce it to pure sugar?

[DeadGood]

Exactly barbara

[DeadGood]

A dietician (nutritionist? Not sure) once told me in answer to this question that "digestion begins in the mouth"

What's that about? Related to the chewing thing? Surely chewing and puréeing are sort of the same?

[Talcott2007]

I think it's to do with the 'work' your body has to do to digest it....whole means the body has to put more effort and energy into breaking down and absorbing everything and therefore uses more calories during the eating and digesting process...if it is juice or puree it's easier for the body to digest so more of the sugars are left over

[DeadGood]

I've heard that you should drink fresh juice / fruit smoothies right away as otherwise good stuff escapes

Stupid as it sounds, I can sort of believe that... The sugar thing though? Magicking up sugar where it wasn't before? Whhhhhaaaaa?!

[lolalament]

Your teeth use energy to chew. But your blender is using electricity

[Temporaryname137]

When I had GD, the dietitian explained it to me like a parcel. The sugar is on the inside and the fruit itself is like the brown paper wrapping. So it takes your body much more time and effort to process it, whereas purée or juice is already in liquid sugar form!

[LoisEighty]

Normal pureed fruit is fine.

'Sweetened with fruit puree' puree in baby yoghurts etc is super concentrated until it is basically just sugar with no other nutritional value.

Juices/smoothies lack fibre and have loads more sugar than you would consume if eating fruit eg. you wouldn't sit down and eat 6 oranges in one go.

[DeadGood]

Talcott I kind of get that, but not fully.

What work is involved in digestion? I can't believe that the act of chewing, or the action of the stomach lining really takes that much effort? Or does it?!

[ClopySow]

It's to do with how your body deals with the sugar.

Whole fruit still has a fibrous structure which you absorb the sugar slowly from. Something different happens with pureed fruit and it makes your blood sugar spike which fucks with everything. And ting.

I just read that on the internet.

[DeadGood]

"Your teeth use energy to chew. But your blender is using electricity"

Seriously?! You can't honestly believe that the action of chewing uses up so much energy that to remove it (via purée) renders the entire fruit pure sugar?

What??

[FrameyMcFrame]

When you purée or juice fruit the complex structures inside the fruit are destroyed.
Your body processes the sugar much more quickly, which means more insulin is released into your blood which causes fat to be stored in the body.

[HarveySchlumpfenburger]

You might regret asking this OP. I get the feeling this thread will end up making you more confused rather than less.

[GerdaLovesLili]

Wait! Is it like if you eat sucrose your body turns it into glucose and then into energy.....but if you eat glucose the energy is already there without the extra work?

[Grumpyaboutchristmas]

Clopysow sounds the most plausible so far, the other explanations don't make any sense to me whatsoever. Any scientist out there who can explain the difference?

As someone who has a smoothie for breakfast every day (God bless The Bullet) with a banana, berries, oats, yogurt, seeds and (a small glass of) fresh fruit juice all whizzed up, I'll be fucking gutted if I may as well start the day with a can of coke (although I'd bloody love that). I honestly thought my breakfast was as good as it got.

[Grumpyaboutchristmas]

Ps I'm whippet thin, so the fat issue doesn't bother me Framey, does that make it healthy for me?

[DeadGood]

Clopy I can get behind that. So you can get to the sugar faster, so you spike. Ok. So the amount of sugar is the same but the access is different?
Which leads me to the next question which is if the amount of sugar is the same... Is spiking a bad thing? So, you get all the sugar at once. Is that bad? And why?

[DeadGood]

framey that makes even more sense. So insulin is the baddie here?

I am prepared to believe this. I just needed compelling evidence!

[ItsAllGoingToBeFine]

When you purée or juice fruit the complex structures inside the fruit are destroyed.

Have you got any links? I'd be interested to read more. I can understand it with juice as you filter out a lot of the pulp/fibre, but if you blend a fruit you don't lose anything, and I doubt a blender can destroy (I'm assuming) very small complex structures.
