alt hed: The Poop about Stool Sample Tests & Personalized Nutrition. Changing your diet to improve your health has been a tradition for people with diabetes, obesity and other chronic conditions. But new and sophisticated knowledge about biochemistry, nutrition, and artificial intelligence has given people more tools to figure out what to eat for good health, leading to a boom in the field of personalized nutrition.Personalized nutrition, often used interchangeably with the terms “precision nutrition” or “individualized nutrition” is an emerging branch of science that uses machine learning and “omics” technologies (genomics, proteomics, and metabolomics) to analyze what people eat and predict how they respond to it. Scientists, nutritionists, and health care professionals take the data, analyze it, and use it for a variety of purposes including identifying diet and lifestyle interventions to treat disease, promote health, and enhance performance in elite athletes.Increasingly, it’s being adopted by businesses to sell products and services such as nutritional supplements, apps that use machine learning to provide a nutritional analysis of a meal based on a photograph, and stool-sample tests whose results are used to create customized dietary advice that promises to fight bloat, brain fog, and a myriad of other maladies.”Nutrition is the single most powerful lever for our health,” says Mike Stroka, CEO of the American Nutrition Association (ANA), the professional organization whose mandate includes certifying nutritionists and educating the public about science-based nutrition for health care practice. “Personalized nutrition will be even bigger.”In 2019, according to ResearchandMarkets.Com, personalized nutrition was a $3.7 billion industry. It is expected to reach $16.6 billion by 2027. It is expected to be worth $16.6 billion by 2027. Scientists began to look at how genes influence how we eat and how our bodies react. Consider coffee for example: Some people can metabolize caffeine and other nutrients in coffee in a productive and healthy manner. Others don’t. Others don’t. The gut microbiome is the least-known organ in the body. It contains more than 1000 species and other microbes. It weighs in at nearly a pound and produces hormones, digests food the stomach can’t and sends thousands of different diet derived chemicals through our bodies each day. The microbiome is crucial to understanding nutrition and is used by nutritionists, researchers, and health care professionals to measure the microbiome and the chemicals it produces (known as metabolites). These data are sometimes combined with self-reported data from surveys or interviews to provide nutrition advice.
