Industrially processed pizzas, cereals, and convenience foods are responsible for a host of diseases. Policymakers and doctors need to lead the food fight.

@sinnerman That article is much better, thanks for sharing it! I'd never thought of ultraprocessing as predigestion before.

For a time, Kevin Hall, a nutrition and metabolism scientist at the National Institutes of Health, was also skeptical that ultra-processed foods were harmful.

To test the idea, he designed a study that compared what happened when men and women were recruited to live in a lab and fed different diets. In one phase of the study, the participants ate mostly ultra-processed foods for two weeks. Their daily meals consisted of things like honey nut oat cereal, flavored yogurt, blueberry muffins, canned ravioli, steak strips, mashed potatoes from a packet, baked potato chips, goldfish crackers, diet lemonade and low-fat chocolate milk.

In a second phase of the study, the participants were fed a diet of mostly homemade, unprocessed foods for two weeks that was matched for nutrients like salt, sugar, fat, and fiber. Their meals consisted of foods such as Greek yogurt with walnuts and fruit, spinach salad with grilled chicken, apple slices, bulgur and fresh vinaigrette, and beef tender roast with rice pilaf, steamed vegetables, balsamic vinaigrette, pecans and orange slices.

In both cases, the participants were allowed to eat as much or as little of the foods and snacks as they wanted.

“If it was really about the nutrients — and not about the processing — then there shouldn’t be any major difference in calorie intake between these two diets,” said Hall. “I thought that was going to be the result of the study.”

But, he added, “I was hugely wrong.”

When people ate the ultra-processed diet, they consumed substantially more calories — about 500 more calories a day compared to when they ate the mostly unprocessed diet. The result: They gained weight and body fat.

The researchers also noticed a difference in how quickly the participants consumed their food. They ate the ultra-processed meals significantly faster, at a rate of about 50 calories per minute, compared to just 30 calories per minute on the unprocessed diet.

Fascinating.

To say that this makes processed foods bad for you however is kinda ridiculous imo. Might as well tell people to only eat raw things because it has the least calories / most filling.

Bad food is bad for you, eating junk food is known to be a giant waste of calories and how it's prepared doesn't make it better or worse.

Outside of increased calories I have not seen any evidence that food being more "processed" is actually bad for you.

I'm not sure when this movement against junk food became a movement against processed foods but it's moving in the wrong direction. Plenty of shitty junk foods can have very little processing involved. And I'm convinced it's exactly those "low processed" junk food providers that are pushing all this bullshit.

"High consumption of ultra-processed foods has been linked to health concerns ranging from increased risk of obesity, hypertension, breast and colorectal cancer to dying prematurely from all causes."

Hall recruited 20 healthy adult volunteers to stay at an NIH facility for a four-week period

Wake me up when an actual legit study shows it. And yes obesity is bad and does all the negative things you put in your comment. So does eating too much red meat or consuming too much sodium or.... so on and so forth.

The 2nd article goes into more details

"Ultra-processing degrades the internal structure or “food matrix,” the complex internal structure that not only holds the corn together, but influences the bio-availability of the nutrients, how our bodies use the food and whether we feel full after eating it."
...
"But the process also appears to accelerate the speed at which our digestive tracts absorb glucose and other nutrients from food, causing greater spikes in blood sugar and insulin levels, studies show."
...
“"Extrusion cooking at very drastic pressures and temperatures is a kind of predigestion of your food,” said Anthony Fardet, a nutrition scientist at the French National Institute for Agriculture, Food, and Environment who studies the effects of food processing on health."

I also agree that a study of 20 adults is absurd.
