It sits next to coffee, toast, cereal, and school lunches as if it were almost the same thing as eating an orange.<\/p>\n\n\n\n<p>Biochemist Jessie Inchausp\u00e9, known online as the Glucose Goddess, is challenging that idea in a very direct way. Her warning is not that fruit should disappear from the table, but that modern fruit has been shaped by humans and that juice removes the fiber that helps the body handle sugar.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Fruit is not so simple<\/h2>\n\n\n\n<p>\u201cFruit is not natural. Fruit is the product of human engineering,\u201d Inchausp\u00e9 said during a conversation on \u201cThe Diary Of A CEO.\u201d The line is meant to make people pause, and it does.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"They&#039;re Lying About &#039;Healthy&#039; Foods &amp; Sugar!

Think of today\u2019s banana, with its smooth texture and no hard seeds, compared with older wild versions that were smaller and much less convenient.<\/p>\n\n\n\n<p>That does not make fruit bad. But it does mean the fruit bowl on the kitchen counter is not some untouched relic from the forest. It is also a record of what humans have wanted food to be.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The real issue is juice<\/h2>\n\n\n\n<p>The bigger concern, according to Inchausp\u00e9, comes when fruit is turned into juice. A whole orange contains water, vitamins, plant compounds, and fiber in one package.<\/p>\n\n\n\n<div class=\"gb-element-a00da4e5\">\n<div><div class=\"gb-looper-46613eed\">\n<div class=\"gb-loop-item gb-loop-item-a8390598 post-27220 post type-post status-publish format-standard has-post-thumbnail hentry category-psychology resize-featured-image\">\n<h3 class=\"gb-text gb-text-24a51617\">Read More: <a href=\"https:\/\/okdiario.com\/metabolic\/en\/psychology\/the-psychological-reason-why-some-overly-nice-people-end-up-feeling-lonely-even-when-theyre-surrounded-by-people-27220\/\">The psychological reason why some \u201coverly nice\u201d people end up feeling lonely even when they&#8217;re surrounded by people<\/a><\/h3>\n<\/div>\n<\/div><\/div>\n<\/div>\n\n\n\n<p>Juice keeps some nutrients, but it loses much of the chewy structure that slows eating down. That is the <a href=\"https:\/\/okdiario.com\/metabolic\/en\/nutrition\/americans-favorite-breakfast-is-a-true-comfort-food-but-experts-warn-against-the-deceptive-combination-that-many-order-without-thinking-27102\/\">breakfast trap<\/a>. You can drink the sugar from several oranges in a few minutes, while eating those same oranges would take more time and feel much more filling.<\/p>\n\n\n\n<p>Current U.S. guidance points in the same direction. The <a href=\"https:\/\/medlineplus.gov\/ency\/article\/002093.htm\" target=\"_blank\" rel=\"noopener\">2025 to 2030 Dietary Guidelines<\/a> encourage eating whole fruits and vegetables in their original form and say 100 percent fruit or vegetable juice should be limited or diluted with water.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What the sugar numbers show<\/h2>\n\n\n\n<p>The comparison with <a href=\"https:\/\/okdiario.com\/metabolic\/en\/nutrition\/is-your-sugar-free-soda-causing-your-brain-to-age-a-study-of-12772-people-links-artificial-sweeteners-to-cognitive-decline-that-is-up-to-62-faster-27084\/\">soda<\/a> is where the debate gets uncomfortable. A 1-cup glass of raw orange juice, about 8 ounces, contains around 20.8 grams of total sugar and only about 0.5 grams of fiber, based on nutrition data drawn from <a href=\"https:\/\/fdc.nal.usda.gov\/?utm_source=chatgpt.com\" target=\"_blank\" rel=\"noopener\">USDA FoodData Central<\/a>. That is roughly 5 teaspoons of sugar in a quick pour.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.coca-cola.com\/us\/en\/brands\/coca-cola\/products\/original\" target=\"_blank\" rel=\"noopener\">Coca-Cola<\/a> says a 12-ounce can of regular Coke contains 39 grams of sugar, while a 7.5-ounce mini can contains 25 grams. So the exact comparison depends on the glass or can size, but the broader point still lands. Juice can deliver a lot of sugar very quickly.<\/p>\n\n\n\n<p>Still, orange juice and soda are not identical foods. Orange juice may contain vitamin C and other plant compounds, while soda is mainly a sugary drink. But for blood sugar, the missing fiber matters.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why fiber changes the picture<\/h2>\n\n\n\n<p>Fiber slows digestion and helps keep food moving through the body at a steadier pace. That is why eating an orange is different from drinking orange juice, even if both came from fruit.<\/p>\n\n\n\n<div class=\"gb-element-5104a158\">\n<div><div class=\"gb-looper-ff767e3f\">\n<div class=\"gb-loop-item gb-loop-item-a3ab2a0a post-27201 post type-post status-publish format-standard has-post-thumbnail hentry category-sports resize-featured-image\">\n<h3 class=\"gb-text gb-text-c2ec7b47\">Read More: <a href=\"https:\/\/okdiario.com\/metabolic\/en\/sports\/neither-running-nor-walking-the-exercise-that-according-to-experts-strengthens-the-heart-and-reduces-cardiovascular-risk-after-age-40-27201\/\">Neither running nor walking: the exercise that, according to experts, strengthens the heart and reduces cardiovascular risk after age 40<\/a><\/h3>\n<\/div>\n<\/div><\/div>\n<\/div>\n\n\n\n<p>This is also why \u201cnatural sugar\u201d can be a confusing phrase. Sugar molecules from fruit juice and sugar molecules from other <a href=\"https:\/\/okdiario.com\/metabolic\/en\/nutrition\/its-not-sugar-but-its-not-magic-either-the-sugar-free-sweetener-found-in-keto-bars-and-diet-sodas-could-set-off-the-brains-defense-mechanisms-27125\/\">sweet drinks<\/a> are not given a special passport once they enter the bloodstream. The body still has to process them.<\/p>\n\n\n\n<p>What changes is the food matrix, meaning the full structure of the food around that sugar. In plain English, it is the difference between biting, chewing, and swallowing a whole fruit and drinking a sweet liquid on an empty stomach.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">A more nuanced finding<\/h2>\n\n\n\n<p>A 2026 randomized crossover trial in healthy young men looked at about 10 ounces of 100 percent orange juice and compared it with sugar-matched drinks that had less or none of the orange juice \u201cfruit matrix.\u201d The researchers found that 100 percent orange juice significantly lowered the peak <a href=\"https:\/\/okdiario.com\/metabolic\/en\/nutrition\/a-team-from-the-cnrs-has-identified-the-sugar-switch-that-triggers-memories-and-the-key-lay-in-some-hungry-flies-25047\/\">glucose response<\/a> compared with a sugar-only orange-flavored drink.<\/p>\n\n\n\n<p>That is an important nuance. It suggests orange juice may not behave exactly like plain sugar water in every setting, especially because it contains compounds beyond sugar.<\/p>\n\n\n\n<p>But the same study also had limits. It included 25 healthy young men, measured short-term responses, and the authors said the findings cannot be generalized to women, older adults, or people with metabolic disorders such as prediabetes or type 2 diabetes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What health agencies recommend<\/h2>\n\n\n\n<p>The <a href=\"https:\/\/www.who.int\/publications\/i\/item\/9789241549028\" target=\"_blank\" rel=\"noopener\">World Health Organization<\/a> recommends reducing free sugars throughout life and says adults and children should keep them below 10 percent of total daily energy intake. It also suggests that going below 5 percent may bring additional benefits, which is often described as about 25 grams, or roughly 6 teaspoons, per day for an average adult.<\/p>\n\n\n\n<div class=\"gb-element-dd2b7ad4\">\n<div><div class=\"gb-looper-368fc37e\">\n<div class=\"gb-loop-item gb-loop-item-950cde84 post-27193 post type-post status-publish format-standard has-post-thumbnail hentry category-psychology resize-featured-image\">\n<h3 class=\"gb-text gb-text-dbfd2779\">Read More: <a href=\"https:\/\/okdiario.com\/metabolic\/en\/psychology\/most-people-dont-realize-that-patience-isnt-just-about-putting-up-with-things-in-many-cases-its-the-ability-to-prevent-anger-anxiety-or-impatience-from-taking-over-before-the-more-level-headed-par-27193\/\">Most people don&#8217;t realize that patience isn&#8217;t just about putting up with things; in many cases, it&#8217;s the ability to prevent anger, anxiety, or impatience from taking over before the more level-headed part of oneself has a chance to react<\/a><\/h3>\n<\/div>\n<\/div><\/div>\n<\/div>\n\n\n\n<p>Here is the key detail. WHO counts sugars naturally present in fruit juices as \u201cfree sugars,\u201d while sugars inside intact whole fruits are treated differently. That is why a whole orange and a glass of orange juice do not carry the same nutrition message.<\/p>\n\n\n\n<p>For most people, the practical takeaway is simple. Eat the fruit. Keep juice occasional, small, or diluted, especially if breakfast is already packed with sweet foods.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Better breakfast choices<\/h2>\n\n\n\n<p>What does this look like in real life? It may mean swapping a large glass of orange juice for a whole orange, a bowl of berries, or fruit paired with plain yogurt, eggs, nuts, or another protein-rich food.<\/p>\n\n\n\n<p>It may also mean rethinking the rushed morning routine. A sweet drink on an empty stomach can feel refreshing, but it may not keep you satisfied for long. Who has not felt that midmorning crash after a fast, sugary breakfast?<\/p>\n\n\n\n<p>People managing diabetes, prediabetes, or blood sugar swings should be especially careful and follow personalized advice from a clinician or registered dietitian. For everyone else, the goal is not fear. It is awareness.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The bottom line<\/h2>\n\n\n\n<p><a href=\"https:\/\/okdiario.com\/metabolic\/en\/nutrition\/this-fruit-could-hydrate-your-body-more-effectively-than-a-glass-of-water-says-nutritionist-22259\/\">Fruit<\/a> still belongs in a healthy diet. In fact, U.S. guidance lists fruits and vegetables as daily staples and encourages people to choose whole, minimally processed foods.<\/p>\n\n\n\n<div class=\"gb-element-20beebca\">\n<div><div class=\"gb-looper-f72b9584\">\n<div class=\"gb-loop-item gb-loop-item-596a91d6 post-27208 post type-post status-publish format-standard has-post-thumbnail hentry category-nutrition resize-featured-image\">\n<h3 class=\"gb-text gb-text-e3753514\">Read More: <a href=\"https:\/\/okdiario.com\/metabolic\/en\/nutrition\/the-mistake-millions-make-when-buying-healthy-bread-why-the-dark-color-can-completely-fool-you-27208\/\">The mistake millions make when buying \u201chealthy\u201d bread: why the dark color can completely fool you<\/a><\/h3>\n<\/div>\n<\/div><\/div>\n<\/div>\n\n\n\n<p>The problem is the health halo around juice.
