DNA testing for nutrition involves analyzing an individual's genetic makeup to gain insights into how their genes influence their nutritional needs, metabolism, and response to different dietary components. This type of testing focuses on variations in specific genes that are related to traits like metabolism, nutrient absorption, food sensitivities, and more.
RNA testing for nutrition, on the other hand, focuses on analyzing an individual's RNA molecules, which are involved in the expression of genes and the production of proteins. RNA testing can provide information about how genes are being actively expressed in response to different dietary factors.
A DNA SNP, which stands for "Single Nucleotide Polymorphism," is a common type of genetic variation that occurs within a person's DNA sequence. It represents a single-letter change in the DNA code at a specific location in the genome. This variation is a result of one nucleotide (a building block of DNA) being replaced by another at a specific position in the DNA sequence.
Single: SNP refers to a change involving a single nucleotide, meaning only one letter of the DNA code is altered.
Nucleotide: DNA is made up of a sequence of four different nucleotides: adenine (A), thymine (T), cytosine (C), and guanine (G). SNPs involve the substitution of one of these nucleotides with another.
Polymorphism: This term indicates that the variation is common in the population. In other words, SNPs are genetic changes that are found in more than 1% of the population.
