Me watching the video about Abbey: 😏👏🤘
Me watching the video about me: 😲😒🤨🧐

(Also - I do agree with you that I shouldn’t have said “IS” leading to all of these issues vs 'is associated with'. But we all make mistakes lol)

If you eat ultra processed foods all the time you feel pretty bad, that's just a fact

[lindz]

As a watcher of both you and Kiana, I rewatched her video and I wanted to point out a few things I think you misrepresented about her video: 1. She clearly explains what she means by "predigested" 2. She makes a clear distinction between processed and ultra processed food. 3. She uses lot's of qualifying words such as "may be" or "could be" even in the first few minutes. At the end of the day, she's giving people something to think about in terms of reducing the amount of ultra processed food they eat which lets face it, is a major issue in our western diet, so what's so terrible about that?

[alexwilder]

As an Australian, her video on the most obese country in the world was absolutely vital. I do not hesitate to tell people here how our meat consumption is effecting the lives of others overseas. Perhaps that video was predigested information, too, but either way it hooked me in, I watched it and I got value out of it and now I deeply care about something I previously didn't even know about.

[Jessamine]

I don't know what kind of apple pie people are making, but for me the one from the store is crazy sweet. Homemade pie is definitely more nutritious and has barely any added sugar, so I absolutely don't agree that it's comparable.

[mynameisambertoo]

I hate the lack of basic chemical knowledge either. Hydrolysis is a common reaction that happens *everywhere*. Not just the stomach. Your body does hydrolysis outside of digestion. This is why comparing something to a hyper specific action does more harm. Hydrolysis, to be plainly simply, is just... a reaction involving water.

[TC-byil]

I usually like these videos and the nuance is important, but I feel like you were a little too nitpicky on this one. Clearly the point was that some processing of food has an effect of how satiating it is, based on specific physiological responses. Hunger hormones and the brain is more than just macros.

[GlowBreeze]

I tend to prefer the term "hyper-palatable food" because it cuts more closely to the actual issue.

[e_i_e_i_bro]

Are we pretending we have no idea what people are talking about when referring to Processed foods? We're usually referring to the types of foods that many scientists are deeply concerned with. The ones with additives, hormone dysruptors, and 200% of your daily value of sugar. Again, we're obviously not talking about boiling pasta or beans. I'm genuinely confused by this video because we have systematic reviews and meta analyses on this subject. There's a strong link between ultra processed foods and poor physical and mental health.

[andreaglowig]

So I didn't bother to rewatch Kiana's video but I do remember watching it and then ending up buying a copy of Chris van Tulleken's book "Ultra-Processed People" about the drawbacks of ultra-processed food. I highly suggest reading it and trying to debunk his claims instead of going after Kiana's video - to me it seems like she just tried to do some sort of "teaser" for this important and complex issue.

[alenfishman]

I just recently learned I'm sensitive to emulsifiers, I always had wacky poops, so I figured that's what life was. But s few years ago, I learned I had food sensitives. Just a few weeks ago, I figured out emulsifiers was a big factor. Now my intestinal issues are much better. I'm 40, so that sucks it took so long. Who knows how much damage I've done to my body because of these things.

[gmcrow]

Yeah, I am a fan of Kiana but this video had me confused. Like it's trying to create fear of "predigested food" when to me that doesn't sound as bad as she is making it out to be. Yes, don't eat all these heavily processed foods often, but it being "predigested" doesn't make it worse than other foods.

[TasteOfButterflies]

You have to admit it's pretty funny that she's demonizing predigested food while basing her video on predigested information.

[culverculver]

Overall I agree with most of the points you made, but I feel like I have to defend the Kevin Hall study on the effect of food processing on calorie intake. The aim of the study was to investigate the effect of food processing (and only food processing) on intake. The difference in the meals looks funny because it’s not necessarily reflective of how a real world meal would be put together, but that’s because the aim of the study was to vary the extent of food processing while controlling for the density & total amount of energy, macronutrients, and fiber. If I remember correctly, they even tried to equate the palatability of the foods, as measured by subjective participant ratings. Of course the sample size was small, as the trial involved strictly controlling and measuring people’s food intake over a period of weeks. I think the real takeaway from the study is that food processing can lead to overeating by simply making food physically easier/faster to consume, regardless of nutrient content and even how tasty it is, and that this effect is significant enough to amount to hundreds of calories per day.

F.e. experts always recommend getting vitamins and minerals from food sources instead of vitamin pills. Also, foods that contain phytonutrients such as antioxidants have been shown to be beneficial for health. Yet extracted antioxidants have been found to have no benefit or have even been shown to have detrimental effect. Nutrition as a science is new and there's tons experts don't yet know. Every real health experts suggests to avoid processed especially ultra processed foods. You can't just use cronometer as a source to show there's no difference. Foods are made up on such a large variety of different compounds that interact with each other that to look at macro and micro nutrients is only a small part of it

PS I don't think original video said potato chips or apple pie is healthy. Just that ultraprocess them and it's even worse.
PPS canned beans is probably fine and healthy although lately people have been starting to pay attention to chemicals such as bpa, microplastics etc and their negative effects on health.

[gordonv.cormack]

I think that "hyper palatable" is probably more important than "ultra processed." Hyper-palatability is defined as two of: high salt, high sugar, high fat. There's some evidence that of the pairings high salt + high fat is the worst. I have experimented on myself by comparing my response to strawberry twizzlers vs. JuJube candies. They are both basically 1/2 sugar and 1/2 modified starch. But the Twizzlers are laced with sodium, and I have a great deal of trouble stopping eating them. JuJubes no problem. I still eat quite a few in a sitting, but then I feel full & stop. Similarly, I can eat a protein bar and not want another; a candy bar not so much.

[justicejones]

Its bizarre to hear someone say that processed food is "nutrient devoid" when the problem with it is that it's nutrient dense. Fats, and carbs are nutrients too, and processed foods have A LOT of them. I think it makes more sense to say they are devoid of micro nutrients, bc processing foods removes or destroys many vitamins, minerals and other components like polyphenols.

I usually enjoy Kiana's content a lot but this video didn't feel like her usual standard at all!

2:45: pan-frying broccoli with just olive oil and salt: This is actually one of my favorite things to eat as part of my lunch!!!

[jaime]

Studies are emerging that show ultraprocessed food leads to weight gain. This is compared to eating the exact same number of calories of whole foods, which are also matched for macros and micros.

Ultraprocessed food is also correlated with increased hunger, so a greater drive to overeat on top of that. Ultraprocessed food is also correlated with depression.

It’s probably very complex, but gut flora likely has a lot to do with it. The wolf you feed, sort of thing.
