DESCRIPTION: Measuring the effects of a plant-based diet on the expression of hundreds of different genes at a time, a research group found that an antioxidant rich portfolio of plant foods such as berries, pomegranates, purple grapes, red cabbage, oregano, and walnuts was able to significantly modify the regulation of genes in the blood of volunteers. This is the final video of a three-part series about the latest discoveries on kiwi fruit. See also Tuesday's NutritionFacts.org video-of-the-day (http://nutritionfacts.org/video/kiwifruit-for-irritable-bowel-syndrome/) and yesterdays's video-of-the-day (http://nutritionfacts.org/video/kiwifruit-and-dna-repair/). The results of this follow-up study support the previous work on the importance of dietary diversity that I profiled in Apples and Oranges (http://nutritionfacts.org/video/apples-and-oranges-dietary-diversity/) and Garden Variety Anti-Inflammation (http://nutritionfacts.org/video/garden-variety-anti-inflammation/). The study of thousands of foods I mention is referring to Antioxidant Content of 3,139 Foods (http://nutritionfacts.org/video/antioxidant-content-of-3139-foods/), and Antioxidant Power of Plant Foods Versus Animal Foods (http://nutritionfacts.org/video/antioxidant-power-of-plant-foods-versus-animal-foods/). Note this study is measuring so-called "epigenetic" changes, meaning differential gene expression. Just because we have a certain set of genes doesn't mean you can't turn them on and off with changes in your diet. See Mitochondrial Theory of Aging (http://nutritionfacts.org/video/mitochondrial-theory-of-aging/) and Convergence of Evidence (http://nutritionfacts.org/video/convergence-of-evidence/) and the other thousand plus nutrition and health topics I address at http://nutritionfacts.org/topics/.
