Friday Favorites: Are Pre-Cut Vegetables Just as Healthy?

Endotoxins can build up on pre-chopped vegetables and undermine some of their benefits.

Here are those old videos I mentioned: The Exogenous Endotoxin Theory (https://nutritionfacts.org/video/the-exogenous-endotoxin-theory/) and Dead Meat Bacteria Endotoxemia (https://nutritionfacts.org/video/dead-meat-bacteria-endotoxemia/).

52 Risposte a “Friday Favorites: Are Pre-Cut Vegetables Just as Healthy?”

  1. It’s far cheaper (as well as healthier) to cut & chop your own + it lasts longer as the rest isn’t chopped up + less waste + more health gains to your body (compared to shop pre chopped). Lots of pluses… 👍

  2. would this effect happen with cooked vegetables aswell? I usually prepare them in bulk and store them in the fridge for the next 5 days.

  3. that is why they all say whole plant foods, the more you process them and longer you store them the worse it gets.

  4. I usually buy whole vegetables in good quantities and chop myself, mix and keep freezed (to be steamed) or fridged (to be eaten raw) in portions of 3 to 4 servings.

  5. 0:16 Okay, so if you’ve lost your egg and sausage sandwich virginity, having already destroyed your arterial health, you might as well give up and wallow in egg and sausage sandwiches for the rest of your short life.

  6. Good, but surprised there's no mention of (low/no salt) fermentation. Lactic Acid Bacteria can metabolize some endotoxins and reduce or eliminate any pathogenic bacterial load on cut veggies. Study: "Isolation of Endotoxin Eliminating Lactic Acid Bacteria and a Property of Endotoxin Eliminating Protein."

  7. I hear and understand. I'm still going to buy prechopped cabbage, and I'm still going to make my breakfast salad before bed (which almost always is low fat and sos free). But, I will memorize this detail in case I ever need some extra anti-inflammatory boost. Life is a balance of limited resources. But, I love learning about all the research, so I can make informed decisions (good or bad). Thanks Dr. Greger and team!

  8. Big fan here, but 1 onion study?
    Granted the word "maybe" was said, like the evidence based mindset should with lesser data, but still isn't it a bit of a grasp to generalise that to all vegetables?

  9. Here's something interesting to add. What it means I'll leave to all of you. I have two pigmy goats and they love vegetables, even freshly cut; but if I give them frozen precut veggies (takes a few minutes to thaw outside, btw) they not only ignore them like they're poop, they give me the stink eye like I played a bad joke on them. Subtle humor aside, they will NOT touch the purchased frozen precut veggies, whereas, they will devour fresh uncut veggies (like kids given free rein in a candy store), even if they were *refrigerated first. Go figure.
    *Note: I refrigerateed them for only one day to serve them the treat on Thanksgiving.

    Dunno if the reasons are applicable to this video, but I will say I always assumed that wherever these precut veggies were sourced, that wherever they were sourced failed to list some chemical spread over said veggies. In fact, it's because of this is why I now only eat fresh veggies and not the frozen (more convenient) veggies sold in stores. Thoughts? Please share. Thx.

  10. I always have felt that pre-chopped is not as fresh and tasty as fresh chopped fruits and veggies. Lately I chop up onion and keep that in the refrigerator for a few days for my dinner salad, but it looks like I am better off chopping a little onion just before I make the dinner salad.

  11. Makes me wonder about spices. We mostly use whole and grind them fresh for better flavor, but the same issues probably apply to preground. Hopefully at a lower level because spices are higher antibiotic than veg.

  12. I wonder what the study would find with frozen chopped vegetables vs if we bought whole vegetables, chopped and froze them for meal prep ourselves? We've always been taught that the store bought frozen were "just as healthy or better than fresh" because they are flash frozen. Side note: My horse will not eat baby carrots but loves big whole carrots broken into smaller pieces. I always thought that it was because of the bleach wash process that they go through. I stopped buying the baby carrots because of this.

  13. Does that count for frozen veggies too? Like broccoli, peppers etc.?😢🌱 It’s so easy, cheap and always accessible 🙇🏼‍♀️

  14. I wonder what this would mean for meal prepping too? It’d be nice if there was a paper showing the change in inflammatory status over time. Like how soon after freshly chopping should you consume the foods?

  15. Could be frozen or canned is the best way to go. Recently heard that produce that’s grown to be frozen or canned tends to have lower amounts of pesticides, etc. And pathogens are not an issue. Frozen and canned are also picked closer to full ripeness. That’s why a can of tomatoes will almost always taste better than a tomato you buy in the produce aisle that was picked green two weeks ago. Those canned tomatoes were picked ripe. One problem though, you can’t buy frozen salad greens.
