Nutrigenomics/Nutrigenetics

-

The field of nutrigenetics and nutrigenomics are becoming more prevalent in today’s society. Nutrigenetics is role of DNA sequence variation in the response to nutrients (Bouchard-Mercier, Descroches, & Vohl, 2016). Nutrigenomics identifies how the nutrients and food alter the DNA transcription and translation process and how the gene that regulate metabolic pathways are affecting health outcomes. In simpler terms, nutrigenomics is the study of what we eat and how that has an impact and/or manipulate on our gene expressions and chronic disease management. Nutrigenetics is the study of how genetic variation effects dietary responses, nucleotide polymorphism, reduce a patient’s risk of developing a certain disease, and DNA interacting with food. Genes and diet interaction can help determine predisposition to disease and help identify how diet responds to the gene (Dennet, 2017).
With different diets being available in society with little or inaccurate information can alter a person’s health. As expects in nutrition, dietitians can help educate and inform people of how food and nutrients can alter genes for better or worse. There is a need for education regarding nutrigenetics and nutrigenomics to push for personalizing medicine and nutrition based on the patient individually. Nutrigenomics and nutrigenetics is still a new field of study to dietitians. Registered dietitians with less than five years of experience were more likely to be exposed to nutrigenomics in college (Bouchard-Mercier, Descroches, & Vohl, 2016). This results in the higher acceptance and interest in nutrigenetics in newer dietitians.  There is not a lot of educational content available directly for registered dietitians about nutrigenetics. There needs to more educational content available to help dietitians motivate clients to change their diet and lifestyle using individualized data. Everyone responds to food/diets differently and nutrigenomics will look at every single nucleotide polymorphism interaction with diet, disease, and other health issues (Dennet, 2017). It can see how the body and cells changes due to nutrient interactions. If we have more data to help back up our reasonings as to why an individual’s health and lifestyle can change for the better by altering their food intake, they may be more likely to follow their diet prescription. Prescribed diets by dietitians can help individualize them based on their genome and genetic variations even more than how it is already being individualized. There is so much that needs to be learned and an endless amount of benefits if nutrigenomics and nutrigenetics become more prevalent in nutrition counseling.

Do you struggle with pre and post exercise nutrition?

What should i eat before and after a workout? First things first…carbohydrates, proteins and fats are important for the body before  and after exercise. Exercising muscle preferentially uses carbohydrates from stored glycogen, but fats are also an important fuel source for energy production during exercise. Fats and carbohydrates are the two major fuel sources during exercise. Fats must be translocated and broken down from their storage form before they are used. Typically there is enough carbohydrate stored as muscle glycogen for exercise but as muscle glycogen stores decline, the skeletal muscle will then use some amino acids (basic components of all protein). More specifically, the amino acid leucine is used for energy.              It is important to consume an adequate amount of carbohydrates exercise to delay fatigue and minimize gastrointestinal distress. It is also important to consume enough fluids to prev...

Child Malnutrition

New approach to childhood malnutrition may reduce relapses, deaths http://www.sciencedaily.com/releases/2015/02/150211124024.htm               Moderate acute malnutrition is experienced by 35 million children worldwide. A new study led by researchers from Washington University School of Medicine in St. Louis has suggested that feeding children until they have met target measures of arm circumference and weight may be more important than a set 12 week feeding time. However, researchers have found that the current targets, set by the World Health Organization (WHO) may not be sufficient and raising these targets slightly could significantly reduce the risk of relapse in malnourished children; a condition that has a 37% relapse rate. The study took place in rural Malawi and was comprised of 2,349 moderately malnourished children aged 6 months to 5 years old. Children were evaluated 12 months after treatment; 1,967 rec...
