Food as Medicine: Christa Orechio at TEDxVillageGate Christa Orecchio is a clinical and holistic nutritionist and founder of The Whole Journey, a private nutrition practice and informational website established to help people live healthier, coque iphone xr happier, and more energetic lives through whole food nutrition, quality supplementation, soldes coque iphone 2019 and healthy lifestyle guidance. Christa’s goal is to holistically heal chronic health concerns from the root cause, coque iphone 6 in lieu of addressing individual symptoms. coque iphone She also focuses on elements that nourish other than food, acheter coque iphone en ligne including honest and open relationships, a meaningful spiritual practice, a career or creative outlet that inspires, soldes coque iphone and physical activity that is enjoyable.
Robyn O’Brien At TEDx Austin Robyn shares her personal story and how it inspired her current path as a “Real Food” evangelist. coque iphone 6 Grounded in a successful Wall Street career that was more interested in food as good business than good-for-you, coque iphone 2019 this mother of four was shaken awake by the dangerous allergic reaction of one of her children to a “typical” breakfast. coque iphone 8 Her mission to unearth the cause revealed more about the food industry than she could stomach, coque iphone 2019 and impelled her to share her findings with others. coque iphone Informative and inspiring.
Once nurture seemed clearly distinct from nature. Now it appears that our diets and lifestyles can change the expression of our genes. coque iphone 6 How? By influencing a network of chemical switches within our cells collectively known as the epigenome. This new understanding may lead us to potent new medical therapies. vente de coque iphone Epigenetic cancer therapy, for one, already seems to be yielding promising results. http://www.pbs.org/wgbh/nova/body/epigenetics.html
In biology, and specifically genetics, epigenetics is the study of heritable changes in gene activity that are not caused by changes in the DNA sequence; it also can be used to describe the study of stable, long-term alterations in the transcriptional potential of a cell that are not necessarily heritable. Unlike simple genetics based on changes to the DNA sequence (the genotype), the changes in gene expression or cellular phenotype of epigenetics have other causes, thus use of the term epi- (Greek: επί- over, outside of, around) -genetics. The term also refers to the changes themselves: functionally relevant changes to the genome that do not involve a change in the nucleotide sequence. coqueiphone
Examples of mechanisms that produce such changes are DNA methylation and histone modification, each of which alters how genes are expressed without altering the underlying DNA sequence. coque iphone
Gene expression can be controlled through the action of repressor proteins that attach to silencer regions of the DNA. coque iphone
These epigenetic changes may last through cell divisions for the duration of the cell’s life, and may also last for multiple generations even though they do not involve changes in the underlying DNA sequence of the organism; instead, non-genetic factors cause the organism’s genes to behave (or “express themselves”) differently. (There are objections to the use of the term epigenetic to describe chemical modification of histone, since it remains unclear whether or not histone modifications are heritable.) One example of an epigenetic change in eukaryotic biology is the process of cellular differentiation. During morphogenesis, totipotent stem cells become the various pluripotent cell lines of the embryo, which in turn become fully differentiated cells. In other words, as a single fertilized egg cell – the zygote – continues to divide, the resulting daughter cells change into all the different cell types in an organism, including neurons, muscle cells, epithelium, endothelium of blood vessels, etc., by activating some genes while inhibiting the expression of others. In 2011, it was demonstrated that the methylation of mRNA plays a critical role in human energy homeostasis. The obesity-associated FTO gene is shown to be able to demethylate N6-methyladenosine in RNA.
