How does blending/processing fruits/veggies remove the fibre?

Something I don't understand is, how can blending vegetables/fruit remove their fibre? I mean, we chew them until they are fine also, don't we? What's the difference then if you save yourself the chewing work and just swallow it?

  • There isn't really, why are you assuming there is?
  • It does not. If you use a juicer though, then many of them, if not all, will only give you the juice, without the fruit pulp, so less fiber. If you just take the fruit, puree it and then eat everything, of course nothing changes. The only potential problem is regarding vitamin c, because it gets oxidized when exposed to air, and pretty fast, so if e.g. you blend your fruit, and consume the mix 2 hours later, you have lost vitamins.
  • Oh okay. There are some veggies (spinach, broccoli, cauliflower, peas) that I can't stomach whole. So it's easier for me to get them in my body if they are a finer texture. But I am eating so much of them for their fibre, (helps out my tum) that's why I'm asking.

    I didn't assume it's something I read that baffled me.
  • Juicing and blending are often confused. As described above, juicing leaves behind a lot of the good stuff, whereas blending leaves it in.
  • Also, off topic question, because I don't want to create another thread:

    Those instant oatmeal packages which you just add boiling water to, do you think you could double their volume by adding twice the water like with normal oatmeal? And not have it be like soup?
  • Nah, you could probably get away with a little extra water, but the oats have a saturation point and after that they won't absorb any more water and it will either stay soup or boil off, which defeats the purpose of adding more water in the first place.

    heat damages the structure of vegetables. This renders varying amounts of their fiber useless to your body. For example, steaming or boiling carrots or broccoli destroys much of their soluble fiber. Deep-frying a potato breaks down both the insoluble and soluble fiber, leaving very little your body can utilize. For the highest fiber retention, eat your vegetables raw or as close to raw as possible. Cooking your vegetables, through boiling or any other method, can reduce the fiber your body can use by almost half.

  • if you want more fibre in your diet, the one thing that is excellent is linseed and flaxseed. You can get both sorts milled and they go great on salad or porridge or in your smoothies.
    They will definitely keep you regular

    Really? Lol thank you, you just saved me money. I was going to order some from Amazon later and some chia seed. That's not the same as well is it.
  • Hehe nah,chia seeds are different. I have both chia and flaxseed in my smoothies everyday.

    And here I thought I couldn't find flaxseeds ANYWHERE! :neutral: when actually all the damn supermarkets have them. Lol. Benefits of being illiterate. :lol:

    Well you learn something new every day ha ha i did not know that
  • Well I'm just happy I helped someone today xx
    Go forth and enjoy your flaxseed/linseed or whichever you choose to call it :)
  • @SkinnyMiss053 , if you want to bulk up your oatmeal, try adding a tablespoon of chia. The soluble fiber on those seeds is truly amazing.

    I call BS. Insoluble fiber is called that for a reason. I can't imagine that boiling, frying, or baking would reduce it at all. Now there might be a case that vitamins, minerals, and antioxidants are destroyed by cooking, but not always. A recent study found that beta-carotene is absorbed better from cooked carrots.

    I believe in the UK we call flaxseed Linseed so it's the same thing. Heard this yesterday on one of those commercials fro nutribullets.
