So, should bananas be banished from your smoothies? It all depends on your goals, says science. <a href=\"https:\/\/pubs.rsc.org\/en\/content\/articlelanding\/2023\/fo\/d3fo01599h\" target=\"_blank\" rel=\"noopener\">Research published in the Royal Society of Chemistry\u2019s <em>Food and Function<\/em> journal<\/a>, looking to find the best combination of fruits for your smoothie, found that adding banana significantly decreases the level of heart-healthy flavonoids, leading scientists from the University of California, David, to conclude that blending certain ingredients together can positively, or negatively, influence the health-boosting effects of your beloved smoothie. Apparently, <a href=\"https:\/\/www.ucdavis.edu\/health\/news\/right-combo-getting-most-health-benefits-fruit-smoothies\" target=\"_blank\" rel=\"noopener\">it\u2019s all down to an enzyme called polyphenol oxidase<\/a> and how it interacts with flavanols, the bio active compounds that benefit the heart and brain. Polyphenol oxidase, or PPO, can be seen when it reacts with the air and turns the fruit\u2019s peel and flesh brown.<\/p>\n<p>\u201cWe sought to understand, on a very practical level, how a common food and food preparation like a banana-based smoothie could affect the availability of flavanols to be absorbed after intake,\u201d said the study\u2019s lead author, Javier Ottaviani.<\/p>\n\n<div class=\"link-related article link-related__with-thumb\">\n\t\t\t<a class=\"article__thumbnail\" href=\"https:\/\/www.muscleandfitness.com\/muscle-fitness-hers\/hers-nutrition\/7-effective-nutrients-boost-your-immune-system-now\/\" target=\"_blank\">\n\t\t\t<figure class=\"article__figure\">\n\t\t\t\t<div style=\"padding-bottom:56%;\" class=\"ratio-based-placeholder\"><img loading=\"lazy\" decoding=\"async\" src=\"\/wp-content\/themes\/muscle-and-fitness\/assets\/build\/images\/placeholders\/default-muscleandfitness.svg\" data-src=\"https:\/\/i0.wp.com\/www.muscleandfitness.com\/wp-content\/uploads\/2020\/03\/immune-boosting-foods-1109.jpg?w=150&amp;h=84&amp;crop=1&amp;quality=86&amp;strip=all\" srcset=\"\" data-srcset=\"https:\/\/i0.wp.com\/www.muscleandfitness.com\/wp-content\/uploads\/2020\/03\/immune-boosting-foods-1109.jpg?w=150&amp;h=84&amp;crop=1&amp;quality=86&amp;strip=all 150w, https:\/\/i0.wp.com\/www.muscleandfitness.com\/wp-content\/uploads\/2020\/03\/immune-boosting-foods-1109.jpg?w=280&amp;h=158&amp;crop=1&amp;quality=86&amp;strip=all 280w, https:\/\/i0.wp.com\/www.muscleandfitness.com\/wp-content\/uploads\/2020\/03\/immune-boosting-foods-1109.jpg?w=300&amp;h=169&amp;crop=1&amp;quality=86&amp;strip=all 300w, https:\/\/i0.wp.com\/www.muscleandfitness.com\/wp-content\/uploads\/2020\/03\/immune-boosting-foods-1109.jpg?w=400&amp;h=225&amp;crop=1&amp;quality=86&amp;strip=all 400w, https:\/\/i0.wp.com\/www.muscleandfitness.com\/wp-content\/uploads\/2020\/03\/immune-boosting-foods-1109.jpg?w=560&amp;h=315&amp;crop=1&amp;quality=86&amp;strip=all 560w, https:\/\/i0.wp.com\/www.muscleandfitness.com\/wp-content\/uploads\/2020\/03\/immune-boosting-foods-1109.jpg?w=600&amp;h=337&amp;crop=1&amp;quality=86&amp;strip=all 600w, https:\/\/i0.wp.com\/www.muscleandfitness.com\/wp-content\/uploads\/2020\/03\/immune-boosting-foods-1109.jpg?w=700&amp;h=394&amp;crop=1&amp;quality=86&amp;strip=all 700w, https:\/\/i0.wp.com\/www.muscleandfitness.com\/wp-content\/uploads\/2020\/03\/immune-boosting-foods-1109.jpg?w=800&amp;h=450&amp;crop=1&amp;quality=86&amp;strip=all 800w, https:\/\/i0.wp.com\/www.muscleandfitness.com\/wp-content\/uploads\/2020\/03\/immune-boosting-foods-1109.jpg?w=940&amp;h=529&amp;crop=1&amp;quality=86&amp;strip=all 940w, https:\/\/i0.wp.com\/www.muscleandfitness.com\/wp-content\/uploads\/2020\/03\/immune-boosting-foods-1109.jpg?w=1200&amp;h=675&amp;crop=1&amp;quality=86&amp;strip=all 1200w\" sizes=\"auto, 280px\" alt=\"7 Effective Nutrients to Boost Your Immune System Now \" width=\"150\" height=\"84\" data-fallback-img=\"https:\/\/i0.wp.com\/www.muscleandfitness.com\/wp-content\/uploads\/2020\/03\/immune-boosting-foods-1109.jpg?quality=86&amp;strip=all\"><\/div>\t\t\t<\/figure>\n\t\t<\/a>\n\t\n\t<div class=\"article__content\">\n\t\t\t\t\t\t<a class=\"article__category\" href=\"https:\/\/www.muscleandfitness.com\/category\/muscle-fitness-hers\/hers-nutrition\/\">Hers Nutrition<\/a>\n\t\t\t\t\t<h3 class=\"article__title\">\n\t\t\t<a class=\"article__title-link\" href=\"https:\/\/www.muscleandfitness.com\/muscle-fitness-hers\/hers-nutrition\/7-effective-nutrients-boost-your-immune-system-now\/\" target=\"_blank\">7 Immune System-Boosting Nutrients<\/a>\n\t\t<\/h3>\n\n\t\t\t\t\t<p class=\"article__subtitle\">Fight a case of the cold with these immune-enhancing herbs and supplements<\/p>\n\t\t\n\t\t<a href=\"https:\/\/www.muscleandfitness.com\/muscle-fitness-hers\/hers-nutrition\/7-effective-nutrients-boost-your-immune-system-now\/\" class=\"article__more\" target=\"_blank\">Read article<\/a>\n\t<\/div>\n\n<\/div>\n\n<h2>How was the study carried out?<\/h2>\n<p>The researchers had participants drink a smoothie made with a banana\u2014naturally high in PPO\u2014and a second smoothie made with mixed berries. Individuals were also provided with a flavonoid capsule for control purposes. Blood and urine samples were then analyzed to determine the presence of flavanols in the body.<\/p>\n<h2>What were the results?<\/h2>\n<p>The banana\u2019s effects were significant and contributed to an up to 84% lower level of flavonoids in the body. \u201cWe were really surprised to see how quickly adding a single banana decreased the level of flavanols in the smoothie and the levels of flavanol absorbed in the body,\u201d said Ottaviani. \u201cThis highlights how food preparation and combinations can affect the absorption of dietary compounds in foods.\u201d<\/p>\n<p>So, should bananas be banished from smoothies? It\u2019s a matter of nutritional goals, explained Ottaviani. Banana\u2019s offer a variety of other <a href=\"https:\/\/www.muscleandfitness.com\/nutrition\/lose-fat\/10-superfoods-super-health-2\/\" target=\"_blank\" rel=\"noopener\">benefits, including heart-healthy potassium<\/a>, digestion aiding fiber, and energy boosting carbohydrates and vitamins. But for those who want to use their smoothie to boost flavanols, other options might work better. To choose the right fruit pairing, Ottaviani says reaching the recommended target of 400 to 600 milligrams of flavanols per day, for cardiometabolic health, involves choices like combining flavol-rich fruits such as berries with fruits that are naturally low in PPO, like pineapple, oranges, or mango.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Smoothies are a super-convenient option for grabbing healthy nutrients while on the go, but a new study has found that adding a banana could cut the body\u2019s absorption of flavanols by 84%.
