For the most part they've evolved to eat veg, fruit, grains and small amounts of meat.

I'd love to see a definition of " normal" food wink
I note you've missed the bit about evolving to drink calories in the form of smoothied fruit.

Normal food would be whatever you eat to get through the day. If you then consume hundreds of calories in the form of fructose on a regular basis, it really won't end well.

Juice bars are fine as an occasional thing. I really wouldn't recommend using them thinking their in some way healthy.

Fyi, I am a medical doctor
What's wrong with fructose?
In terms of the chemistry please. If you are an md you should know the answer.
Your phrasing suggests that you don't believe he is a medical doctor.

I prefer to take posters at their word.

A glance at the Wikipedia page gives this

"As for any sugar, excessive consumption of fructose may contribute to insulin resistance, obesity, elevated LDL cholesterol and triglycerides, leading to metabolic syndrome, type 2 diabetes and cardiovascular disease"

Look up Dr Lustig's video's on Youtube,or other MDs research.

Essentially when you eat a piece of fruit/Veg, you are eating a combination of fibre and fructose which your body handles fine. However when you break this down into juice, the body does not handle it right and you may as well be having normal sugar.

As said, juices are fine if occasional but take care. Also along with the sugar hit, another problem with juices is that they may not fill you up, so many people have a smoothie and then also a breakfast when the smoothie had enough calories to be the breakfast.

That's nothing to do with the chemistry.

Blending doesn't break things down at the chemical level. What do you think your stomach does to the food you eat?

Hey, I'm not the researcher(s). Go read the findings and then say how you disagree

Example of what I'm looking for.

If the topic was maltose. I would say it's a disaccharide consisting of two glucose molecules joined at alpha 1-4 carbons. A brush border enzyme called maltase catalyses the hydrolysis of maltose into the mono saccharide glucose.

Example of what I am looking for. You as our new resident internet expert to go and read the research and tell us how it is all wrong.

When should we expect a reply Liam??

Answering a question with a question is poor form.

Expert? This is very basic biochemistry

Expecting to be spoon fed is also poor form.

From my side it is quite simple, I have no particular interest scientifically so if the prevailing opinion from people who are qualified in the field are saying this is the case, then I am inclined to believe them untill evidence is presented to the contrary.

You on the other hand appear to want to deep dive and challenge the current thinking, however instead of going to the source and seeing what is what, you instead want to be on a Pistonheads thread playing expert.

So go and read the research and come up with your own finding, if you do find it is flawed than congrats and hope you get the resulting fame and fortunes from it.

Let me know when your done with your work smile

Spoon fed?

I asked a question to someone claiming to be an md.

I gave an example of an answer as irevelant things were being posted.

Maybe I will read the research one day, but im not even in medical school yet. I'm still an undergraduate.

Looks like you have found it then, well done you.

Nah, I don't understand it.

But they say a little knowledge is a dangerous thing, and it seems you have been taught something recently and feel you can call out a medical doctor based on that. Bad form on your part.

Your GP will not know the biochemistry involved in eating an orange Vs drinking some juice. Not over and above what anyone not living under a rock knows anyway. It's not their job to know and they don't need to.

It'd be a dietician that knows all the technical stuff about that sort of business.

So you wanted an answer that related directly to your own field of study, hoping to catch out another poster, rather than discuss whether the products of juice bars are healthy.

Very true

No. This is stuff taught at A level

and feel you can call out a medical doctor based on that. Bad form on your part.

A medical doctor should know this. It's very very basic stuff.

They certainly would have taught it. Whether they remember it is another matter

Again no. This is basic biochem that any a level student should be able to tell you.

It is directly related to whether juice bars are healthy.
