But at this USDA kitchen, there\u0027s no pinch of this, dash of that, no dollops or smidgens of anything. Here, nutritionists in white coats painstakingly measure every single ingredient, down to the tenth of a gram.Sheryn Stover is expected to eat every crumb of her pizza; any tiny morsels she does miss go back to the kitchen, where they\u0027re scrutinized like evidence of some dietary crime.Stover (or participant #8180, as she\u0027s known) is one of some 10,000 volunteers enrolled in a $170 million nutrition study run by the National Institutes of Health. \"At 78, not many people get to do studies that are going to affect a great amount of people, and I thought this was a great opportunity to do that,\" she said. It\u0027s called the Nutrition for Precision Health Study. \"When I tell people about the study, the reaction usually is, \u0027Oh, that\u0027s so cool, can I do it?\u0027\" said coordinator Holly Nicastro. She explained just what \"precise\" precisely means: \"Precision nutrition means tailoring nutrition or dietary guidance to the individual.\"The government has long offered guidelines to help us eat better. In the 1940s we had the \"Basic 7.\" In the \u002750s, the \"Basic 4.\" We\u0027ve had the \"Food Wheel,\" the \"Food Pyramid,\" and currently, \"My Plate.\"They\u0027re all well-intentioned, except they\u0027re all based on averages \u2013 what works best for most people, most of the time. But according to Nicastro, there is no one best way to eat. \"We know from virtually every nutrition study ever conducted, we have inner individual variability,\" she said. \"That means we have some people that are going to respond, and some people that aren\u0027t. There\u0027s no one-size-fits-all.\"The study\u0027s participants, like Stover, are all being drawn from another NIH study program called All Of Us, a massive undertaking to create a database of at least a million people who are volunteering everything from their electronic health records to their DNA. \u00a0It was from that All of Us research that Stover discovered she has the gene that makes some foods taste bitter, which could explain why she ate more of one kind of food than another. Professor Sai Das, who oversees the study at Tufts University, says the goal of precision nutrition is to drill down even deeper into those individual differences. \"We\u0027re moving away from just saying everybody go do this, to being able to say, \u0027Okay, if you have X, Y and Z characteristics, then you\u0027re more likely to respond to a diet, and somebody else that has A, B and C characteristics will be responding to the diet differently,\u0027\" Das said. It\u0027s a big commitment for Stover, who is one of 150 people being paid to live at a handful of test sites around the country for six weeks \u2013 two weeks at a time. It\u0027s so precise she can\u0027t even go for a walk without a dietary chaperone. \"Well, you could stop and buy candy \u2026 God forbid, you can\u0027t do that!\" she laughed. While she\u0027s here, everything from her resting metabolic rate, her body fat percentage, her bone mineral content, even the microbes in her gut (digested by a machine that essentially is a smart toilet paper reading device) are being analyzed for how hers may differ from someone else\u0027s.\u00a0Nicastro said, \"We really think that what\u0027s going on in your poop is going to tell us a lot of information about your health and how you respond to food.\" \u00a0Stover says she doesn\u0027t mind, except for the odd sounds the machine makes. While she is a live-in participant, thousands of others are participating from their homes, where electronic wearables track all kinds of health data, including special glasses that record everything they eat, activated when someone starts chewing. Artificial intelligence can then be used to determine not only which foods the person is eating, but how many calories are consumed.This study is expected to be wrapped up by 2027, and because of it, we may indeed know not only to eat more fruits and vegetables, but what combination of foods is really best for us. \u00a0The question that even Holly Nicastro can\u0027t answer is, will we listen? \"You can lead a horse to water; you can\u0027t make them drink,\" she said. \"We can tailor the interventions all day. But one hypothesis I have is that if the guidance is tailored to the individual, it\u0027s going to make that individual more likely to follow it, because this is for me, this was designed for me.\"\u00a0 \u00a0 \u00a0\u00a0For more info:Nutrition for Precision Health Study (National Institutes of Health)\u00a0 \u00a0 \u00a0Story produced by Mark Hudspeth.

But according to Nicastro, there is no one best way to eat. "We know from virtually every nutrition study ever conducted, we have inner individual variability," she said. "That means we have some people that are going to respond, and some people that aren't. There's no one-size-fits-all."</p> <div id="mpu-plus-outstream-middle" data-ad="mpu-plus-outstream-middle" class="ad-mpu-plus-outstream-middle ad-wrapper " data-ad-unit='"mpu-plus-outstream-middle"'> </div> <p>The study's participants, like Stover, are all being drawn from another NIH study program called <a href="https://allofus.nih.gov/" target="_blank" rel="nofollow noopener">All Of Us</a>, a massive undertaking to create a database of at least a million people who are volunteering everything from their electronic health records to their DNA. It was from that All of Us research that Stover discovered she has the gene that makes some foods taste bitter, which could explain why she ate more of one kind of food than another. </p><p>Professor Sai Das, who oversees the study at Tufts University, says the goal of precision nutrition is to drill down even deeper into those individual differences. "We're moving away from just saying everybody go do this, to being able to say, 'Okay, if you have X, Y and Z characteristics, then you're more likely to respond to a diet, and somebody else that has A, B and C characteristics will be responding to the diet differently,'" Das said. </p><p>It's a big commitment for Stover, who is one of 150 people being paid to live at a handful of test sites around the country for six weeks – two weeks at a time. It's so precise she can't even go for a walk without a dietary chaperone. "Well, you could stop and buy candy … God forbid, you can't do that!" she laughed. </p><p>While she's here, everything from her resting metabolic rate, her body fat percentage, her bone mineral content, even the microbes in her gut (digested by a machine that essentially is a smart toilet paper reading device) are being analyzed for how hers may differ from someone else's. </p> <div id="leader-plus-inc3" data-ad="leader-plus-inc" class="ad-leader-plus-inc ad-wrapper " data-ad-unit='["leader-plus-inc",3]'> </div> <p>Nicastro said, "We really think that what's going on in your poop is going to tell us a lot of information about your health and how you respond to food." </p><figure class="embed embed--type-image is-image embed--float-none embed--size-large"><span class="img embed__content"><img src="https://assets1.cbsnewsstatic.com/hub/i/r/2024/11/23/8bd05701-cfd2-43b3-b4e6-7ac200b2bd4c/thumbnail/620x349/498ce613fab14369da8ceadbc8adaa56/microbe-reader.jpg?v=b1635869826311f914073798d8df6484#" alt="microbe-reader.jpg " height="349" width="620" class=" lazyload" data-srcset="https://assets1.cbsnewsstatic.com/hub/i/r/2024/11/23/8bd05701-cfd2-43b3-b4e6-7ac200b2bd4c/thumbnail/620x349/498ce613fab14369da8ceadbc8adaa56/microbe-reader.jpg?v=b1635869826311f914073798d8df6484 1x, https://assets3.cbsnewsstatic.com/hub/i/r/2024/11/23/8bd05701-cfd2-43b3-b4e6-7ac200b2bd4c/thumbnail/1240x698/4a28c1e0f78da44cb9e9be6141d4a53d/microbe-reader.jpg?v=b1635869826311f914073798d8df6484 2x" srcset="data:image/svg+xml,%3Csvg%20xmlns%3D'http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg'%20viewBox%3D'0%200%20620%20349'%2F%3E"></span> <figcaption class="embed__caption-container"><span class="embed__caption">Microbiome analysis – studying microbes and genetic material found in the stool samples of program participants – is one of the components of the Nutrition for Precision Health Study. </span> <span class="embed__credit"> CBS News </span> </figcaption></figure><p>Stover says she doesn't mind, except for the odd sounds the machine makes. While she is a live-in participant, thousands of others are participating from their homes, where electronic wearables track all kinds of health data, including special glasses that record everything they eat, activated when someone starts chewing. Artificial intelligence can then be used to determine not only which foods the person is eating, but how many calories are consumed.</p><p>This study is expected to be wrapped up by 2027, and because of it, we may indeed know not only to eat more fruits and vegetables, but what combination of foods is really best for <em>us</em>. The question that even Holly Nicastro can't answer is, will we listen? "You can lead a horse to water; you can't make them drink," she said. "We can tailor the interventions all day. But one hypothesis I have is that if the guidance is tailored to the individual, it's going to make that individual more likely to follow it, because this is for <em>me</em>, this was designed for <em>me</em>."</p><p><strong> <br>For more info:</strong></p><ul><li><a href="https://nutritionforprecisionhealth.org/" target="_blank" rel="nofollow noopener">Nutrition for Precision Health Study (National Institutes of Health)</a></li></ul><p><em> <br>Story produced by Mark Hudspeth.
