It's simply an industrially produced edible substance.\n\nTake a food product from your kitchen cabinet and check its ingredient list: modified corn starch, soy lecithin, acidity regulators, guar gum, maltodextrin, palm stearin, isolated protein, dextrose, artificial coloring, flavoring, sweeteners, stabilizers... Tiny, densely packed words that are hard to even read. These ingredients are created through sophisticated equipment and complex processes. Crops like corn and soybeans are broken down into components like oil, protein, and starch, chemically modified, then reassembled with additives using industrial techniques like molding, extrusion, and pressure. It wouldn't be an exaggeration to call ultra-processed food the triumph of ever-advancing food processing science.\n\nChris van Tulleken, author of Ultra-Processed People: Why Do We Eat Foods That Aren't Real Food?, states that if even one ingredient on a food label is something you wouldn't commonly find in an ordinary kitchen, that food qualifies as \"ultra-processed.\" By this standard, it's hard to find food that ISN'T ultra-processed. Yet somehow, ultra-processed food has become the poster child for dangerous eating. So what exactly does ultra-processed food do to our bodies?\n\nCancer, cardiovascular disease, dementia, obesity, type 2 diabetes, metabolic disease, eating disorders... Ultra-processed food may be the primary cause of virtually every disease.\n\nTo understand how ultra-processed food affects the body, Chris decided to experiment on himself. For four weeks, he filled over 80 percent of his daily calories with ultra-processed food alone. (This experiment is documented in detail in the widely-discussed BBC documentary, \"What Are We Feeding Our Kids?\") After the experiment, Chris's body underwent several changes: he gained 7 kilograms, developed indigestion, constipation, and hemorrhoids, and experienced reduced concentration and poor sleep. But the most significant change Chris noticed was that his appetite hormones were thrown completely out of balance. The hormone that signals fullness barely responded even after he ate until full, while the hunger hormone spiked even right after meals. Leptin, a hormone released by fat cells, was five times higher than normal, and inflammation markers had doubled.\n\nThese results—showing appetite hormones failing to function normally—mirror findings from a 2019 study led by Kevin Hall. Researchers gave one group of 20 adults an ultra-processed diet and another group an unprocessed diet for two weeks, then switched the diets between groups for another two weeks. Salt, sugar, and fat content were carefully controlled to eliminate variance, and participants were allowed to eat as much as they wanted. The results showed that people on the ultra-processed diet ate an average of 500 more calories per day than those on the unprocessed diet, and naturally gained more weight. What's remarkable is that participants on the unprocessed diet actually lost weight, even though they ate as much as they wanted. It wasn't even that the ultra-processed food tasted better—there was something else, beyond taste, that drove people to overeat ultra-processed food. Since this study, growing evidence increasingly points to ultra-processed food as a primary driver behind the global surge in various health problems.\n\nUltra-Processed Food Is Pre-Chewed Food: How Soft, Dry Textures Drive Overconsumption\n\nSome argue that ultra-processed food is unhealthy simply because it's high in saturated fat, sodium, and sugar while being nutritionally poor. But studies that control for all these factors still produce the same results. This book presents evidence from various studies showing that ultra-processed food isn't harmful merely because it's high in fat, salt, or sugar—the processing method itself is the problem, not the nutritional content. For example, food that has been industrially modified, powdered, and compressed has its fiber structure completely destroyed, becoming extremely soft and easy to chew. In effect, it's essentially \"pre-chewed\" food.","brand":"IBOOKPARK","offers":[{"title":"Default Title","offer_id":49624353145060,"sku":"05122025999","price":36.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0831\/9788\/6692\/files\/9788901288475.jpg?v=1786426769","url":"https:\/\/ibookpark.com\/en\/products\/%ec%b4%88%ea%b0%80%ea%b3%b5%ec%8b%9d%ed%92%88-%ec%9d%8c%ec%8b%9d%ec%9d%b4-%ec%95%84%eb%8b%8c-%ec%9d%8c%ec%8b%9d%ec%97%90-%ec%a4%91%eb%8f%85%eb%90%98%eb%8b%a4","provider":"IBOOKPARK","version":"1.0","type":"link"}
