Change your diet Improving your health is nothing new – people with diabetes, obesity, Crohn’s disease, celiac disease, food allergies, and a host of other conditions have long done so as part of their treatment. But new and evolving knowledge about biochemistry, nutrition and artificial intelligence has given people more tools to learn what to eat for good health, leading to a boom in the field of personalized nutrition.
Personal nutrition, often used interchangeably with the terms Micro Nutrition or individual nutrition It is an emerging branch of science that uses machine learning techniques and “omics” (genomics, proteomics and metabolism) to analyze what people eat and predict how they will respond to it. Scientists, nutritionists, and healthcare professionals take data, analyze it, and use it for a variety of purposes, including determining diet and lifestyle interventions to treat disease, promote health, and improve performance in elite athletes.
Increasingly, it’s being adopted by companies to sell products and services like nutritional supplements, apps that use machine learning to provide nutritional analysis of a meal based on an image, and stool sample tests whose results are used to create personalized nutritional advice that promises to fight bloat, brain fog, and countless other diseases. .
“Nutrition is the most powerful lever on our health,” says Mike Struka, CEO of the American Dietetic Association, a professional organization whose mandate includes accrediting nutrition experts and educating the public about science-based nutrition for healthcare practice. ‘Dedicated feeding will be greater.’
In 2019, according to ResearchandMarkets.Com, personal nutrition was valued at $3.7 billion. By 2027, it is expected to be worth $16.6 billion. Among the factors driving this growth are consumer demand, the lower cost of new technologies, greater ability to provide information, and a growing body of evidence that there is no such thing as a one-size-fits-all diet.
The sequencing of the human genome, which began in 1990 and ended 13 years later, paved the way for scientists to find easier and more precise links between diet and genetics.
When the term “personalized nutrition” first appeared in the scientific literature, in 1999, the focus was on using computers to help educate people about their nutritional needs. It wasn’t until 2004 that scientists began to think about the way genes influence how and what we eat, and how our bodies respond. Take coffee, for example: Some people metabolize the caffeine and other nutrients in coffee in a productive and healthy way. Others do not. The camp you fall into depends on a range of factors including genetics, age, environment, gender and lifestyle.
Recently, researchers have been studying the links between the health of the gut microbiome and disease conditions including Alzheimer’s disease, Parkinson’s disease, and depression. The gut microbiome, the body’s least known organ, is made up of more than 1,000 species of bacteria and other microbes. It weighs about a pound, produces hormones, digests food the stomach can’t, and sends out thousands of chemicals derived from different diets roaming our bodies every day. In many respects, the microbiome is key to understanding nutrition and is the basis of growth in personalized nutrition.
