All food is just macros, in the end. You can become obese eating healthy food, as many can attest. Plenty of overweight or obese vegans due to too much nuts or tofu.

Obese vegans don’t eat too much tofu and nuts. That would be quite a challenge. Potato chips, Oreos, candy, alcohol, there’s plenty of tasty stuff to binge on

A trajectory question: have we have definitive answer to why the US now has so many obese people when before 70s not so many (or I just got the wrong impression from poor sampling of videos)? It's not like the US didn't have enough supply of food or people didn't have access to cars. The US was wealthy then and still wealthy now.

The most likely explanation is that back in the 70s, the dietary villain of the day was high-fat foods. So manufacturers switched to low-fat varieties and marketed them based on the lower fat content. But foods in which the fat was lowered tasted blander, so to compensate they added a potent flavorant -- sugar. Sugar was safe, right? It was a simple carbohydrate, not a fat, so it wouldn't make you fat... right?

IMO the problem is the definition. According to wikipedia UPF is "an industrially formulated edible substance derived from natural food or synthesized from other organic compounds. The resulting products are designed to be highly profitable, convenient, and hyperpalatable, often through food additives such as preservatives, colourings, and flavourings." The Wikipedia features a photo of fruit loops breakfast cereal b…

It is a confusing definition. I wouldn’t consider most bread and pasta to be ultra processed but simply processed (except the bread that lasts for weeks). Ultra processed in my mind is when you take the source materials down to constitute parts and then Frankenstein a new food item out of it. Like Pringles. And then a traditional actual sliced potato chip is processed food because it’s a deep fried sliced potato. The…

> It’s also confusing because I’ve had lentil or chickpea pasta which is ultra processed but has higher fiber and is probably healthier.

That's why I think the nutrition value is the right way to look at it. The lentil pasta I've seen usually still has all its protein and fiber content like whole wheat pasta, but semolina pasta and white bread are made by first removing the bran and germ from the wheat which removes a lot of the nutritional value. That's why I'm arguing that white bread and pasta are ultra processed, whereas other foods like whole wheat and lentil pasta are highly processed, but not UPF.

IMO removing the bran and germ and milling it is taking the materials down to constituent parts and Frankensteining a new food item out of it. It's not as extreme as getting down to basic chemistry but it's still ultra processing.

The (sliced) potato chip is an interesting outlier. I don't think they're particularly processed but they're not very healthy to begin with. Focusing on UPF to the exclusion of nutrition value is a trap though.

When I go hiking for long periods of time, I make sure to include lots of nuts in my pack. Pecans and peanuts are staples, but macadamia nuts are best of all: They're the most calorie-dense food on the planet, at about 720 calories per 100g.

Peanut Butter Twix -- the apotheosis of ultra-processed calorie-dense junk food -- isn't even close, at 536 calories per 100g.

One can easily gain lots of weight by eating too many nuts -- and it takes fewer of 'em than one might think.

Obesity is on the rise globally, not just in the US (though the US is leading the pack).

I don't think we've figured out exactly what's causing it. The simplest explanation is an abundance of easy, cheap calories. Some think it's some unknown/unstudied environmental factor like PFAS. There are various other theories. It's another unsolved billion dollar question.

I’ll save you the trouble of researching this - we don’t know the answer to this and probably won’t in this lifetime.

We still don’t understand how amino acids are able to perform such complex functions. We have zero understanding of how the same exact cell in every sense can evolve into different organs in the human body. We don’t even know how we fall asleep, or the complete role of serotonin and melatonin on sleep and mood - their interactivity (which influences which).

So who knows how the amino acids or whatever are the constituents of the foods we consume interact in our body. It’s definitely not a black and white answer. Depends on what exactly are we talking about and the physiology of the individual that likely influences it.

What always gets lost in the great diet debate is that if you did (preferably high intensity) routine exercise that will represent a far greater improvement to your health.

Note I am also not talking about weight or weight loss. I am talking about being healthy, generally in the "lives longer and lives better" deconstruction of "healthy".

Yeah looks like you could use the term "modern" food and it'll be as (in)accurate for the food group they want to refer

Processed foods were actually a boon in the 50s because they were much better than the alternative, which was often rotten food or simply starving. Famine was a real danger late into the 20th century even in the USA. The memories of WWII and Dust Bowl famine were still fresh in adults' minds. And foods spoiled quickly unless pickled, refrigerated, etc. So anything that could prolong the shelf life and make the food supply stretch while still remaining appetizing was welcome from a food security standpoint -- even with all those additives and preservatives. The trope of "starving kids in China would be glad to eat that" was a thing for a reason; under Chairman Mao people really were starving in China, and starvation was still almost at your doorstep even in the USA.

These days we have agro-tech out the wazoo and can, potentially, feed billions with fresh crops reliably and relatively cheaply, so the processed stuff doesn't have the advantages it once had and numerous disadvantages.
