Up to 15% of the observed association was explained by the gut microbiome suggesting these microbes play a key role in metabolising flavonoids to enhance their cardioprotective effects.<\/p>\n<p>The study of &gt;900 German adults found that higher habitual intakes of flavonoid-rich foods, specifically berries, red wine, apples\/pears were associated with clinically relevant reductions in systolic blood pressure and pulse pressure, greater microbial diversity and lower abundance of Parabacteroides<\/p>\n<p>These blood-pressure-lowering effects are achievable with simple changes to the daily diet. Eating ~1.5 servings berries\/day was associated with a 4.1 mmHg reduction in systolic BP, and 12% of the association was explained by gut microbiome factors. Drinking ~3 glasses\/week of red wine was associated with 3.7 mmHg lower systolic BP levels, of which 15% could be explained by the gut microbiome.<\/p>\n<p>Prof Cassidy, also based in the School of Biological Sciences at Queen\u2019s University Belfast said: \u201cOur gut microbiome plays a key role in metabolising flavonoids to enhance their cardioprotective effects, and this study provides evidence to suggest these blood pressure-lowering effects are achievable with simple changes to the daily diet.<\/p>\n<p>\u201cOur findings indicate future trials should look at participants according to metabolic profile in order to more accurately study the roles of metabolism and the gut microbiome in regulating the effects of flavonoids on blood pressure. A better understanding of the highly individual variability of flavonoid metabolism could very well explain why some people have greater cardiovascular protection benefits from flavonoid-rich foods than others.\u201d<\/p>\n<p>The flavonoid\u2013gut microbiome interaction associated with blood pressure highlighted in this paper suggests research should focus on inter-individual variability in the gut microbiome in mediating the cardiovascular benefits.<\/p>\n<p>The analysis of habitual flavonoid intake with gut microbiome and blood pressure levels found:<\/p>\n<p>\u2022 Study participants who had the highest intake of flavonoid-rich foods, including berries, red wine, apples and pears, had lower systolic blood pressure levels, as well as greater diversity in their gut microbiome than the participants who consumed the lowest levels of flavonoid-rich foods.<\/p>\n<p>\u2022 Up to 15.2% of the association between flavonoid-rich foods and systolic blood pressure could be explained by the diversity found in participants\u2019 gut microbiome<\/p>\n<p>\u2022 Eating 80 grams of berries a day was associated with an average reduction in systolic blood pressure levels of 4.1 mm Hg, and about 12% of the association was explained by gut microbiome factors.<\/p>\n<p>Drinking 250ml of red wine a week, just under three small glasses, was associated with an average of 3.7mm Hg lower systolic blood pressure level of which 15% could be explained by the gut microbiome.<\/p>\n<\/div><\/section><br \/>\n<div  class='av-social-sharing-box  avia-builder-el-7  el_after_av_textblock  avia-builder-el-last  av-social-sharing-box-minimal '><div class='av-share-box'><h5 class='av-share-link-description av-no-toc '>Share this<\/h5><ul class='av-share-box-list noLightbox'><li class='av-share-link av-social-link-facebook' ><a target=\"_blank\" aria-label=\"Share on Facebook\" href='https:\/\/www.facebook.com\/sharer.php?u=https:\/\/fei-online.com\/study-shows-flavonoid-rich-foodstuffs-lower-blood-pressure\/&#038;t=Study%20shows%20flavonoid-rich%20foodstuffs%20lower%20blood%20pressure' aria-hidden='false' data-av_icon='\ue8f3' data-av_iconfont='entypo-fontello' title='' data-avia-related-tooltip='Share on Facebook' rel=\"noopener\"><span class='avia_hidden_link_text'>Share on Facebook<\/span><\/a><\/li><li class='av-share-link av-social-link-twitter' ><a target=\"_blank\" aria-label=\"Share on Twitter\" href='https:\/\/twitter.com\/share?text=Study%20shows%20flavonoid-rich%20foodstuffs%20lower%20blood%20pressure&#038;url=https:\/\/fei-online.com\/?p=10029' aria-hidden='false' data-av_icon='\ue8f1' data-av_iconfont='entypo-fontello' title='' data-avia-related-tooltip='Share on Twitter' rel=\"noopener\"><span class='avia_hidden_link_text'>Share on Twitter<\/span><\/a><\/li><li class='av-share-link av-social-link-whatsapp' ><a target=\"_blank\" aria-label=\"Share on WhatsApp\" href='https:\/\/api.whatsapp.com\/send?text=https:\/\/fei-online.com\/study-shows-flavonoid-rich-foodstuffs-lower-blood-pressure\/' aria-hidden='false' data-av_icon='\uf232' data-av_iconfont='entypo-fontello' title='' data-avia-related-tooltip='Share on WhatsApp' rel=\"noopener\"><span class='avia_hidden_link_text'>Share on WhatsApp<\/span><\/a><\/li><li class='av-share-link av-social-link-linkedin' ><a target=\"_blank\" aria-label=\"Share on LinkedIn\" href='https:\/\/linkedin.com\/shareArticle?mini=true&#038;title=Study%20shows%20flavonoid-rich%20foodstuffs%20lower%20blood%20pressure&#038;url=https:\/\/fei-online.com\/study-shows-flavonoid-rich-foodstuffs-lower-blood-pressure\/' aria-hidden='false' data-av_icon='\ue8fc' data-av_iconfont='entypo-fontello' title='' data-avia-related-tooltip='Share on LinkedIn' rel=\"noopener\"><span class='avia_hidden_link_text'>Share on LinkedIn<\/span><\/a><\/li><li class='av-share-link av-social-link-mail' ><a  aria-label=\"Share by Mail\" href='mailto:?subject=Study%20shows%20flavonoid-rich%20foodstuffs%20lower%20blood%20pressure&#038;body=https:\/\/fei-online.com\/study-shows-flavonoid-rich-foodstuffs-lower-blood-pressure\/' aria-hidden='false' data-av_icon='\ue805' data-av_iconfont='entypo-fontello' title='' data-avia-related-tooltip='Share by Mail'><span class='avia_hidden_link_text'>Share by Mail<\/span><\/a><\/li><\/ul><\/div><\/div><\/p><\/div><div class=\"flex_column av_one_fifth  flex_column_div av-zero-column-padding   avia-builder-el-8  el_after_av_three_fifth  avia-builder-el-last  \" style='border-radius:0px;
