1. Fruit is not healthy in large quantities. (Everything in moderation?) 2. If you eat fruit in its natural form (with the fiber etc), it has a much lower glycemic index than processed. Also consider the glycemic index and load of an apple is much lower than a potato. Its worth noting that in the form of something like a smoothy, a person can consume more fruit than would be possible eating actual fruit. Imagine a counter top of fruit turning into a single large smoothy...

Dried fruit is also incredibly deceptive.

Fruit is perfectly healthy in large quantities if it is raw with nothing added. The human body is very capable of processing the sugars in fruit. It's when those sugars get extracted and concentrated we run into trouble. Juices and smoothies are more dangerous because they concentrate the sugars while removing fiber. This decreases the liver's ability to process the sugar. But actual refined sugar is most dangerous.

  Do you have any evidence to back this up? Glucose is glucose and fructose is fructose as far as I know. There are no fundamental chemical changes.
  - hristov 11y ago
    You should check out Dr. Lustig's youtube videos and his papers. He cites plenty of evidence. He also explains the mechanism by which fructose is processed by the liver, and why the fructose in fruits does not cause problems.

      Ah, Lustig. Many of his fellow doctors are not on board with his conclusions: http://www.huffingtonpost.com/david-katz-md/sugar-health-evil-toxic_b_850032.html http://www.huffingtonpost.com/david-katz-md/sugar-health-evi...

    I've read a few papers that suggest our bodies absorb sugars differently in the presence of other chemicals that are present in the fruits themselves, but not in the processed versions? I think this is one of those papers? http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2871121/ http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2871121/

    In its natural form sugar is not singled out and thus other molecules from the fruit influence its absorption. For example, vitamin C in its oxidized form is transported by the same receptors as glucose (GLUT4) and quercetin is very good inhibitor of glucose transport. I still doubt tho, that high quantities of fruit are good for you. One of the reasons is that current forms of fruit we eat are selected toward sweater taste.

  This is all on a continuum, I would concur that large quantities of raw fruit is far better for you than the same payload in say Coca Cola. But is stands that it is possible to become insulin resistant from eating raw fruit, and this is simply not possible from eating eggs for example. In regards to insulin resistance there is an upper bounds of healthy fruit consumption, just there is with almost any food (although for some foods the consideration may bot be blood sugar, but rather be total calories or omega-6 poly-fat, etc)

    Most days I get 80% of my calories from fruit. Actually, eggs increase the risk of diabetes. http://nutritionfacts.org/video/eggs-and-diabetes/ http://nutritionfacts.org/video/eggs-and-diabetes/
    - voidlogic 11y ago
      That is very unlikely, show me some real science (not the one flawed study from a few years ago). Type II diabetes is severe insulin resistance. A food like eggs don't have sugar, your body doesn't produce insulin when you eat them, therefore its not possible through any known mechanism for them to contribute to type II diabetes. http://www.independent.co.uk/life-style/health-and-families/health-news/eating-eggs-and-high-fat-dairy-products-reduces-diabetes-risk-10155460.html http://www.independent.co.uk/life-style/health-and-families/... http://www.express.co.uk/news/uk/577051/Birmingham-University-Diabetes-four-eggs-week-risk-Type-2 http://www.express.co.uk/news/uk/577051/Birmingham-Universit...

        A food doesn't need sugar to produce insulin. A steak produces as much insulin as pure sugar.

        >A food doesn't need sugar to produce insulin. This is true. But non carbs have a much lower insulin response. >A steak produces as much insulin as pure sugar. Are you saying grams of protein to grams of sugar? A steak has a smaller insulin response than a piece of bread, not only that, the shape of the spike is drastically different.

  In what way does a smoothie remove fiber from fruit?
- mrfusion 11y ago
  How would smoothies remove the fiber. You're just grinding up the fruit, not taking anything out. All the fiber should still be there.
CuriouslyC 11y ago
Actually, most fruit is fine even in pretty darn large quantities, due to the fact that the sugar is absorbed slowly, and it is paired with phytonutrients that have anti-oxidant and anti-inflammatory properties. Bananas and dates are the main exceptions to this.
