    What a pointless tread, if you want to make a claim about diet you have to back it up with good scientific papers and i will emphasis good, there's plenty of ****e out there to tell you that McDonald's is good for you and so on.

    Otherwise its just people spouting stuff they heard/read once and took it as gospel.

    I did

    Juicing, smoothies all that stuff. Has to be nonsense. Eat the full thing and stop mashing it up.

    What is your source? This is hilarious!

    Organic food production is governed by EU regulation and strictly implemented by the Department of Agriculture.

    The common misconception is that all organic food is fresh. Sometimes the vendor keeps it too long and all you have are sorry looking wilted vegetables with a high price tag...

    Basically you're mechanically breaking down all of the fibre and turning it into easily absorbed sugar, which will be digested quickly and give you a nice sugar rush and an even nicer sugar crash. Way better off munching the whole fruit and a) digesting the fibre and b) feeling fuller for longer.

    Having said that, my OH won't eat fruit or veg so I blend it and he downs it in one, so it's better than none at all.

    Fair play.

    But realistically unless everyone is doing that, there is no point having the argument, a fact is not a fact unless its backed up with evidence.

    Juicing removes the fiber (contained in the pulp) - making a smoothie does not.

    Breaking down the fibre to sugar??? Are you serious here??

    This thread was about debunking myths, should have been moved to a science forum

    Actually there's studies showing the opposite. You're better off eating your carbs at night as they assist with the production of melatonin, the sleep hormone, who anyone who has gotten drowsy after a carby meal with attest to.

    Carbs at dinner lead to better weight loss.

    Can anyone debunk coconut oil, i've been using it for a while now, and i really like cooking with it and its supposed to be really beneficial but again it was recommended by a friend.

    Coconut oil cannot be debunked, because it's awesome. It does some seriously good stuff to your body. One thing I would advise is Extra Virgin Coconut Oil is totally pointless and not work the extra money. Get the cheap refined stuff if like me, you don't like the taste of it.

    I'm gonna state something that probably no-one will agree with but one of the biggest myths out there is that we all have the same capability to be thin, and that a thin person is always more disciplined than a heavy person. That all you need to do is eat less, like defying hunger every single day for the rest of your life is an easy thing to do.

    Most thin people who were never fat are just lucky. 70% of the differences in body fat between two given people are based on inherited factors. (Note I didn't say genetics, as maternal diet in utero plays a big role also.)

    I agree!:D

    Some really interesting stuff out there on food reward brain signaling and how people differ. For an obese person dieting it really fires up.

    From what I've read (and I've read a lot in the last 5 years), most overweight/obese adults are always going to struggle in the long term; the dysfunction in how their body defends a high bodyfat level will probably be always with them to some degree.

    Sorry I was using simple terms (typing on my phone), I meant that without the stomach needing to break down the fibre into glucose, thus slowing down the absorption, the sugar hits your bloodstream quicker than if you ate the fruit whole.

    It mechanically breaks it down, so the stomach acids do not need to do it chemically.

    You still get the benefit of eating the fibre such as feeling full for longer and keeping everything running smoothly BUT you also make the sugars in the fruits more bio-available so while it is better than juice it's still not a great idea for weight loss and it makes it a lot easier to consume a lot of calories from fruit than you would if you had to chew the individual pieces.

    The following are BS myths


    2. Breakfast is the most important meal of the day - I believe that one, simply cos if I don't have a decent breakfast I can't focus/have no energy

    6.you shouldn't eat carbs after 6pm - If the person tends to be more sedentary after 6pm then I would think they should reduce carbs but I agree about not cutting them out

    And I don't eat until 1pm. It may be important to you but its still a myth.

    Do you think your body shuts down if you aren't moving after 6? Calorie requirements are over the day and even week. Eating after 6 means nothing.

    I think a huge problem here is the tendency to make everything so black and white. Things have advantages and disadvantages; if you took out the terms "must" and "have to" from most of this stuff they'd be worth considering.

    I think another stumbling-block is that different foods /strategies are good for achieving different goals rather than being universally "healthy".

    protein : chicken w/rice tatoes pasta for cholestrol

    chiliis : loads of varieties

    wholemeal vitaminc : kiwis oranges lemons (with skins) other various fruits with their skins(all oraganic) and brocolli.

    100 years plus no joke

    The effects of coconut oil , have they been proven to show benefits in humans or are we talking about lab studies only?

    Yeah but look at the impact of modern life, out of my family the only person who is (now) probably overweight has a different lifestyle to the rest of us. That's not blaming them because to a big extent its understandable time constraints convenience etc etc

    For me the biggest myths are that "organic" offers any advantages over convential vegetables and secondly that antioxidants are beneficial.

    "Organic food is better for you". No it's not. It's wallet-lightening though. (It may taste better, but that's a different issue.)

    It can be, grass fed vs meal fed cows for example.

    And just looking it up atm, found a study which claims organic fruit and vegetables have higher levels of antioxidants and lower levels of heavy metals and pesticides.

    Could also be benefits mentally with people thinking they're eating more environmentally friendly produce and there's less cruelty to animals.

    The benefits of antioxidants are a bit of a myth, think they have actually been associated with higher mortality rates.

    Lower levels of pesticides and heavy metals doesn't necessarily mean better. Does the study define the threshold at which these pesticides and heavy metals constitute a risk to health?

    That article is total garbage. Pacific islanders eating their traditional diet (sadly becoming rarer) eat 50% of the calories as coconut oil and have vanishingly small rates of heart disease. Coconut oil is by no means a panacea, and some of the health claims overstep the mark by a wide margin, but it is a very healthy ingredient.

    Like what were you thinking? There's an RCT that it's good for gum health that was published a while back. There's a good few studies on functional foods that use components of coconut oil to boost cognition. The research is fairly young in terms of human trials, and as I said I wouldn't expect it to cure any disease. But we have a tonne of epidemiological data showing it's very safe to consume. I have a personal bias as I feel it boosts my energy levels and it's convenient.

    Sorry, but my teeth also break down fruit, its soft fruit, not lumps of meat!

    The benefits of having a thick smoothie for someone who wouldnt otherwise be eating that fruit outweight (har har) any negative effects of the fructose.

    Also, a proper smoothie is a meal, if you are treating it like a dessert, expect the same results as eating a dessert.

    According to this article it raises both good and bad cholestrol and other claims have yet to be shown in humans.

    Other factors could explain low heart disease in pacific islanders.

    How so? Are you saying coconut water actually "will do everything from beautifying your skin to boosting your immunity"?

    Or that it isn't " rich in saturated fats"?
