In this new field of inquiry, separating hype from hope.Although the term "precision nutrition" may sound like a new fad diet, it is actually an established field of study supported by the National Institutes of Health under the general heading of "precision Dawae."
1,2 Precision nutrition is focused on nutritional consumption, while precision Dawae aims to improve the individualised treatment of illnesses.
Based on an individual's distinctive traits including DNA, race, gender, health history, and lifestyle choices, both create strategies to prevent or treat chronic diseases. Both seek to offer more precise and targeted solutions for illness prevention and treatment that are safer and more efficient.
According to precision nutrition, every person may react differently to particular foods and nutrients, meaning that the optimal diet for one person may not be the best diet for another.
How many times have we been persuaded to try a fad diet that a friend or celebrity claimed would help them "cure" their diabetes or lose 20 pounds? This method would be discouraged by the idea of precision nutrition, as each person's genetic makeup may necessitate a different dietary strategy.
The microbiome, the billions of bacteria in our bodies that are essential to many daily bodily functions, is another factor taken into account by precision nutrition.
Every person has different bacteria, both in terms of type and quantity. According to precision nutrition, the types of bacteria in our systems may affect how particular foods are broken down and which foods are best for our bodies. Our diets can affect the types of bacteria that reside in our digestive tracts, but the opposite is also true.
THE WAY IT WORKS
Precise nutrition, also known as individualised nutrition, places an emphasis on the individual as opposed to a group. Numerous scientific investigations into diets and nutrition offer communities and the general public vital information. In general, eating more vegetables, whole grains, and lean proteins while consuming fewer highly processed foods with added sugars and salt will help lower the risk of developing a number of diseases, according to high-quality nutrition research. But even though everyone are eating the same meals, studies like the PREDICT 1 trial that focus on individual responses to food have identified significant variability in blood levels of glucose and triglycerides.
After eating, the microbiota of the individual was found to affect blood triglyceride levels. Variations in blood levels of glucose and triglycerides after meals were also influenced by non-food factors like sleep, exercise, and mealtime.
Therefore, if a person follows tailored nutrition advice in addition to standard health suggestions, they may experience additional benefits.
The most efficient eating strategy to ward off or treat disease is determined through precision nutrition, which analyses a person's DNA, microbiota, and metabolic response to particular foods or dietary patterns.
ADVANCED DIETARY METHODS AND DISEASE MANAGEMENT:
A gluten-free diet is used to treat celiac disease, a lactose-free diet is used to treat lactose intolerance, and avoiding dietary phenylalanine (an amino acid found in protein foods and some artificial sweeteners) is used to treat phenylketonuria, an inherited disorder. These specific dietary treatments are based on genetic data and have been used for years.
However, precision nutrition is still in its infancy and is not yet being used as a broad population treatment for chronic disorders. Precision nutrition's use in treating type 2 diabetes, obesity, metabolic syndrome, and several malignancies is now being studied. 4,5.
CONSIDERATIONS AND DIFFICULTIES:
Due to a number of issues, including the absence of well-designed clinical studies with reliable results and the high cost of the technologies required to collect and analyse an individual's DNA, gut flora, and reaction to food consumption, precision nutrition is still in its infancy.
4 Before dietary therapies like these may be suggested for usage in conjunction with or even in place of traditional interventions for a given disease, high-quality evidence of their efficacy and consistency must be provided. Depending on the types of tests they employ, clinical trials of a person's metabolic response to a particular diet may also yield different results, which could lead to variations in the tailored nutrition advice given.
Precision nutrition necessitates the coordinated efforts of the entire healthcare team, therefore primary care doctors, registered dietitians, and other professionals who directly engage with a patient need to be educated on it.
Personalized dietary recommendations should nevertheless adhere to general nutrition principles (e.g., eating more fruits and vegetables, consuming less added sugar from sugary beverages, limiting sodium, etc.) despite individual variances in metabolic response to meals.
Despite the fact that commercial businesses have begun to offer genetic and microbiome testing to the general public in order to modify diets, more research is still needed to determine the efficacy and accuracy of these tests. Protecting customer privacy in the use of precision nutrition technology and testing is one of the ethical and legal considerations that should be made when putting precision nutrition into practise.
Additionally, it's critical to understand that access to individualised techniques may only be available to a tiny portion of the population, which might exacerbate health disparities. We must not lose sight of the importance of enhancing the general food environment through efficient laws, rules, and other population-based strategies that can support the defaulting of healthy food choices.
