Including a Banana to Your Smoothie May Reduce ‘Coronary heart-Wholesome’ Flavanol Absorption by 84%
Smoothies are a super-convenient choice for grabbing wholesome vitamins whereas on the go, however a brand new research has discovered that including a banana may minimize the physique’s absorption of flavanols by 84%. So, ought to bananas be banished out of your smoothies? All of it will depend on your objectives, says science. Analysis printed within the Royal Society of Chemistry’s Meals and Perform journal, seeking to discover the very best mixture of fruits on your smoothie, discovered that including banana considerably decreases the extent of heart-healthy flavonoids, main scientists from the College of California, David, to conclude that mixing sure elements collectively can positively, or negatively, affect the health-boosting results of your loved one smoothie.

Polyphenol oxidase, or PPO, may be seen when it reacts with the air and turns the fruit’s peel and flesh brown.
“We sought to grasp, on a really sensible degree, how a standard meals and meals preparation like a banana-based smoothie may have an effect on the provision of flavanols to be absorbed after consumption,” stated the research’s lead creator, Javier Ottaviani.
How was the research carried out?
The researchers had individuals drink a smoothie made with a banana—naturally excessive in PPO—and a second smoothie made with blended berries. People have been additionally supplied with a flavonoid capsule for management functions. Blood and urine samples have been then analyzed to find out the presence of flavanols within the physique.
What have been the outcomes?
The banana’s results have been important and contributed to an as much as 84% decrease degree of flavonoids within the physique. “We have been actually shocked to see how rapidly including a single banana decreased the extent of flavanols within the smoothie and the degrees of flavanol absorbed within the physique,” stated Ottaviani. “This highlights how meals preparation and combos can have an effect on the absorption of dietary compounds in meals.”
So, ought to bananas be banished from smoothies? It’s a matter of dietary objectives, defined Ottaviani. Banana’s supply a wide range of different advantages, together with heart-healthy potassium, digestion aiding fiber, and power boosting carbohydrates and nutritional vitamins. However for individuals who need to use their smoothie to spice up flavanols, different choices would possibly work higher. To decide on the proper fruit pairing, Ottaviani says reaching the advisable goal of 400 to 600 milligrams of flavanols per day, for cardiometabolic well being, entails selections like combining flavol-rich fruits equivalent to berries with fruits which are naturally low in PPO, like pineapple, oranges, or mango.
