Fructose Toxicity – #drjasonfung #science #shorts

insulin resistance, diabetes, blood sugar, weight loss

Why is Fructose so bad for you? It's all in the way it gets metabolized in our body. Table sugar is 1 molecule of glucose and 1 molecule of fructose. Starches are almost all glucose with no fructose. Almost every cell in the body can use glucose, but not fructose, so all the fructose is delivered to the liver for metabolism, where it can lead to fatty liver and insulin resistance.

    Watch out for those poison blueberries, that’s what’s killing you /s

    Watch out for those killer bananas, they will knock you out instantly 😅

    • @jackiedelvalle says:

      Yup. The moment I stopped eating 2 a day, the weight dropped off. Now I rarely eat fruit and a teeny amount of veg.

    • @nickverduyn7723 says:

      I was just being sarcastic about bananas. I love them. Fruit is the best. Just watch your calories intake and you will be fine.

      For every food there is someone online telling you it’s bad. Meat is bad, being vegan is bad, cheese is bad, carbs are bad, oils are bad, salt is bad and now fruit is bad.

    That means fruits are like poison….😢😢

    • @debiwillis9045 says:

      It’s not just fruits…or all fruits, quite a few vegggues are high in fructans too!

    • @marilynsik-nt3zb says:

      That’s what my oncologist say. You want to lose weight don’t eat fruits . I said what about apple ? Yes you can but in moderation. Fruits are very high in sugar according to my doctor.

    • @africangodman6145 says:

      ​@@marilynsik-nt3zbIt depends on the fruits, research the low glycemic levels in fruits.

    • @marilynsik-nt3zb says:

      @@africangodman6145 highest content of sugar are fruit ending in melon, watermelon for example, grapes has also highest sugar content . So yes . I stop eating those fruits . I love fruits pineapple, anything ends in melon, bananas no wonder I have been putting on so much weight. So when I discovered Dr Jason Fung and Dr Jamnadas I come to realise that yes fasting is the only way to lose weight . I stop the sugar intake and fast . And yes I have lost weight . Without knowing it I fitted on my pants from 20 years ago. I feel lighter . I was 69 kgs then 58 . Haven’t done the 3 days fasting for awhile but doing the intermittent . Whichever one is comfortable just do it. I suppose whatever you do in moderation.

      Yep. Almost like plants are living beings that also don’t want to be eaten or smth

    The best explanation I’ve heard about fructose, always Jason Fung explains in a concise way.

    My thought is frucktose that fructose!!

  • @benisrood says:

    So, wait, are bodies arent evolved for eating fruit?

    • @limekatfruit2 says:

      Fruit has been breeded over hundreds of years by humans to be sweeter and less fibrous. Fruit is healthy in its natural form, not so healthy in smoothies/juices.

      I picked a dozen blackberries a week ago. I picked some last year around this time. Once a year is good for me.

    • @christineguttilla6465 says:

      It isn’t that we aren’t evolved to eat and digest it. It’s where it is metabolized (the Liver) since the cells in your body can’t use it for energy like it can glucose. This leads to fatty liver and insulin resistance.

  • @dehydrohalogenation says:

    Eat all seasonal fruits! They are good for humans! Dont forget to move around, do physical activity! Then you can eat anything!
    Main problem is people becoming couch potato!

  • @knightraider1362 says:

    Doctor Fung I started doing I.F. again because I want to loose weight and purify my body! On the 3d day I stared getting shaky , nervous , and felt like I couldn’t breathe

    • @christineguttilla6465 says:

      That’s called the Keto Flu. It is completely normal. As soon as your body starts to burn fat for energy that will all go away. It’s usually around 3 days for the switch. Hang in.

    WHAT ABOUT FRUIT FRUCTOSE ..

    • @davebboggs2000 says:

      Seasonal…. food pyramid everyday blows out your liver… like being a alcoholic

    • @christineguttilla6465 says:

      Fruit is fructose. You’re conflating high fructose corn syrup with fruit fructose. Fructose is fructose… your body is going to metabolize it the same exact way. Fructose is no good in any form.

  • @paoloa.1821 says:

    That is why fruits are served in hotels in a small bowls. Example. 2 slices of pineapple, 1/2 slice of mango. Anything fruit.

    And now I understand, why some Asians, and I used to pair fruits or dried fruits with Black tea or green tea. Because it helps to lower the effects of insulin spikes.

  • @tonyli2739 says:

    Dr.Fung, would you be more specific and give us some examples…i.e. banana, pineapple, apple, grape, orange, watermelon… etc. thank you!

    • @onlyonecai says:

      We’ve been selective breeding all these for excessive sugar content for hundreds of years, nothing like those in the nature we’ve evolved for. I’d stay away from them as much as possible

    • @christineguttilla6465 says:

      ALL fruit is loaded with Fructose. Lower fructose fruits are only berries but in small quantities. It’s STILL Fructose sugar.
