I’ll Have a Glass of Red Wine, Please
If you’re a wine enthusiast you’re in for a treat. If you’re just like me, who knew nothing about wine and its benefits for cholesterol, then you’re in for a surprise. It turns out that several medical studies done at the University of California, London School of Medicine and other institutions, report a decline in cholesterol after consuming red wine. Now, let’s immerse into the world of wine, shall we?
Red Wine and Saponins
According to Andrew Waterhouse, a PhD in Enology (study of wine chemistry) at UC Davis, scientists have found certain chemicals that may help lower cholesterol. These chemicals are called saponins which are found in grapes’ skin. Researchers believe that saponins bind to cholesterol and prevent absorption. Saponins are also found in other foods such as olive oil, chickpeas and soy beans. The discovery of saponins in wine, specifically in red wine, might give scientists further clues and evidence that red wine has certain health benefits.
For example, let’s take a look at the French Paradox. Cheese, butter, croissants and other very delicious foods are part of the French diet. Even though these foods are delicious, they are very high in fat. Yet, the French heart disease rates are lower than in the U.S. France is also one of the largest consumers of wine. Many researchers believe that there is a link between red wine and the French Paradox. The discovery of saponins will definetly support this link. Or, maybe it’s because the French eat whole foods, not processed, but that’s just a maybe.
Everything in Moderation
Another research study shows that having a glass of red wine daily for a 4 week period increased HDL cholesterol (the good kind) up to 16% while lowering the LDL (the bad kind). The Institute of Preventative Medicine in Denmark showed that moderate consumption of red wine for a period of one month is associated with desirable changes in HDL, even compared to red grape extract. But, moderation is the key. The recommended amount is only around 5 oz. of red wine. One glass of red wine already contains about a half of daily dose of saponins, but one glass was enough to show benefits in lowering cholesterol.
Which Kind Is Better?
For all of you wine enthusiasts, studies showed highest amounts of saponins and antioxidants in red Zinfandel, followed by Pinot Noir and Cabernet Sauvignon. If you’re a fan of white wine, the amount of saponins and antioxidants are much less compared to red wine. Sorry.
So, keep in mind that red wine has more beneficial content than white wine, in case you’re deciding on which wine to drink for today’s dinner.
Whole Foods and Heart Health
It’s interesting to see how researches keep finding more and more healthful chemicals in our foods. Whether its avocados with their beneficial monounsaturated fats or red wine with newly discovered saponins, there are plenty of whole foods available that may help lower cholesterol and benefit our health.
Just remember, when it comes to alcoholic beverages such as wine, use common sense and moderation. If not sure, ask your doctor if you are able to consume one glass of red wine once in a while. Enjoy your dinner!
