How Personalized Nutrition Is Shaping the Future of Food
The functional foods and nutraceuticals market has witnessed significant growth in recent years, and the evolution of personalized nutrition has replaced the concept of a one-size-fits-all approach. Personalized nutrition is precision nutrition that focuses on individuals instead of a group of people. It is a diet recommendation tailored to meet a person’s personal nutritional requirements depending on the genetic profile, personal wellness goals, metabolism, and microbiome composition.
Over time people are becoming more conscious about their food choices and living style. This increase in demand for a healthy lifestyle, along with customization in the food and medicine sector, is leading to the growth of personalized nutrition. According to research, the global market of personal nutrition is increasing at 9.5% CAGR and is expected to reach 2.76 billion dollars by 2025.
What Is Personalized Nutrition?
According to the American Nutrition Association, personalized nutrition is defined as “A domain that harnesses the unique characteristics of individuals to shape nutrition approaches aimed at preventing, managing, and treating diseases while optimizing overall health. It assumes that every individual’s body responds differently to specific foods and nutrition, so a speck of dirt that is best for one individual may have the opposite effect on the body of another individual.
Often people follow a flashy diet plan that a celebrity or a friend promoted through which they lose 20 pounds. Personalized nutrition discourages one-size-fits-all approaches because each individual’s body has unique dietary requirements for optimal success.
What Are The Factors That Trigger Personalization Of Nutrition?
“Personalization” is a buzzword becoming prominent in all sectors and spreading globally. Most businesses are now run by extracting their customers’ personal information and requirements, creating personalized products or services, and using media as a catalyst to promote their customized plans. According to a recent study by Monetate, 93% of businesses use advanced personalization strategies to increase their revenue in different sectors such as insurance, retail, travel, and hospitality.
In this era of customization, nutrition is stepping up its game when it comes to personalized approaches for better health. There are many factors contributing to this trend:
- People now seek personalized experiences in all aspects of their lives, including their dietary choices.
- As consumers become more informed, there is a greater appreciation for the importance of healthy eating.
- Technological advancements enable individuals to continuously monitor their health data and vital signs, allowing for more tailored nutrition plans.
- The rise of personalized medicine has also played a role in driving the personalization of nutrition.
All these factors combined have propelled the field of nutrition to adapt and provide more individualized approaches to support people’s health goals.
What Are The Main Scientific Drivers of Personalized Nutrition?
Implementing effective technology supported by scientific evidence in personalized nutrition is a process that requires time and effort. However, two primary factors play a crucial role in driving personalized nutrition and food supply chain.
1. DNA Profiling
How genes and nutrients interact with each other at a cellular level to dictate an outcome in individuals is known as nutrigenomics or nutritional genomics. We know that the bodies of different individuals metabolize the same nutrients differently depending on their genetic makeup. For example, bodies respond to cholesterol, starch, and caffeine differently.
On the other hand, nutrients also interact with human genomes and alter how genes are expressed. For example, when obese people start a diet and change their dietary carbohydrate intake, their metabolism genes express differently, leading to weight loss. Nutrients also influence epigenetic outcomes, which is changing the expression of genes without altering the DNA. Research shows that long-term intake of folate, Vitamin B12, and Vitamin B6 can cause epigenetic changes that greatly impact our well-being.
Since the milestone achievement of sequencing the human genome in 2003, precision medicine has advanced rapidly. However, our understanding of the intricate relationship between nutrition and our genetic makeup is still in its early stages. Nevertheless, entrepreneurs have recognized the potential in this emerging field and are actively working to provide solutions based on the latest data.
2. Gut Microbiome Analysis
Our gut is a host to trillions of microbes that mostly include bacteria, but fungi, viruses, and protozoa are also present that form our gut microbiome. It is unsurprising that the microbiome DNA displaces that of our own and plays an important role in digestion and metabolism, directly affecting our fitness and health. Though each of us is known to be born with a unique microbiome, many factors help reshape the microbiome population, such as mode of birth, genetic makeup, diet, age, and antibiotics. The gut microbes also produce vitamins and other compounds that humans cannot synthesize, thus determining what nutrients are available in our food.
Completing the Human Microbiome Project in 2012 opened up new possibilities for utilizing the blueprint of an individual’s gut microbiome in personalized nutrition. This approach shows great promise but also calls for further scientific evidence to support its potential benefits fully.
Can Personalized Nutrition Help In Disease Prevention?
Personalized nutrition holds immense potential in preventing and managing various health conditions. Personalized nutrition can be crucial in optimizing health outcomes by tailoring dietary interventions based on an individual’s genetic predispositions, risk factors, and specific nutritional needs. It can assist in managing conditions like diabetes, heart disease, obesity, and gastrointestinal disorders more effectively, helping individuals achieve better control and potentially reducing the risk of complications.
Personalized Nutrition Changing The Behaviour Of Individuals
One of the key strengths of personalized nutrition lies in its ability to empower individuals to take charge of their health. By providing personalized insights and recommendations, individuals can better understand how their unique genetic makeup and lifestyle choices influence their nutritional needs. This knowledge fosters a sense of ownership and motivation, leading to sustainable behavioral changes that support long-term health and well-being.
Challenges And Future Directions Of Personalized Nutrition
While personalized nutrition holds great promise, several challenges remain. The field is still in its infancy, and more research is needed to fully understand the complex interactions between genetics, diet, and health outcomes. Ensuring the privacy and security of personal data is also of utmost importance. Additionally, making personalized nutrition accessible and affordable to a wider population is crucial for widespread adoption.
Conclusion
Personalized nutrition is revolutionizing the future of the food industry by offering tailored dietary approaches that consider an individual’s unique characteristics, genetic profile, and health goals. As the market for functional foods and nutraceuticals grows, the demand for personalized nutrition is rising. This approach acknowledges that a one-size-fits-all approach to nutrition is no longer sufficient and instead focuses on providing customized dietary recommendations to optimize health and prevent diseases.
Integrating scientific advancements, such as DNA profiling and gut microbiome analysis, has paved the way for personalized nutrition to become a prospective approach. By understanding the interactions between genes, nutrients, and the gut microbiome, personalized nutrition can offer targeted interventions for better health outcomes. However, further scientific evidence is still needed to support personalized nutrition’s potential benefits fully.
