How Healthy are Red Wine, Coffee, and Dark Chocolate?
By Claudia Jones
Promoted for their youth-enhancing properties, foods and drinks containing anti-oxidants are increasing in popularity among consumers. The occasional cup of coffee, glass of red wine and square or two of dark chocolate is considered a treat to be savored by many health conscious people; the alcohol, sugar or caffeine content being overlooked in favor of the anti-oxidant benefits.
Wellness Director Claudia Jones takes a look at some of the scientific research into the health benefits of antioxidants in coffee, red wine and dark chocolate and whether we should or shouldn't indulge.
Let's start with coffee
While coffee drinking is not advised for those suffering from high blood pressure, coffee is a rich source of antioxidants and its regular consumption has been linked to protection against certain types of cancer; colon, liver and colo-rectal cancers in particular. It is also been associated with prevention of Parkinson's disease and type two diabetes. Sound good? Well, perhaps hold on before you switch on the coffee machine or rush down to your nearest Starbucks for a mochaccino with two extra shots and know that the caffeine content of coffee is the reason it affects blood pressure levels. Considered rajasic in terms of Ayurveda, caffeine can also make you feel jittery and anxious therefore its that the caffeine content of coffee conducive to yogic practices such as meditation, so keep your intake moderate and consume it at times when you need the extra stimulation, rather than at times when you are trying to experience stillness. The healthiest way to experience the anti-oxidant benefits without consuming the caffeine is by choosing a decaffeinated option (non-chemical process is best).
Red wine is also know for its anti-oxidant health benefits, but isn't consuming alcohol supposed to be bad for our health? Well, the 'French Paradox' may partly help us in answering this. For a culture that has a diet so high in saturated fat, it has a surprisingly low incidence of cardiovascular disease compared to other western cultures and this is thought to be due in part to the regular drinking of red wine. The polyphenols in red wine, such as flavonoids and resveratrol may play a role in limiting the start and progression of atherosclerosis (the formation of fatty plaques in the blood vessels, in particular the coronary arteries, which can lead to heart attacks) and have anti - platelet aggregation benefits.
The evidence, however, is not sufficient for a non-drinker to start drinking red wine as a preventative measure, (we know that excessive alcohol consumption can lead to serious health conditions) but fortunately, resveratrol is actually found in the skin of the red grape and can just as easily be obtained from drinking red grape juice or taking a resveratrol supplement. In Ayurveda alcohol is considered tamasic because it dulls the mind and the senses. So only minimal red wine consumption can be recommended at most a glass or two on occasions; sugar-free red grape juice would be the healthier anti-oxidant boosting option.
The cocoa in chocolate is known to have a very high anti-oxidant capacity and its consumption has been shown to offer significant health benefits. Dark chocolate contains more cocoa and therefore offers more benefits than milk chocolate that contains high levels of milk and sugar and comparatively little cocoa. Raw cacao is superior again containing an abundance of minerals and is the healthiest way to get your chocolate 'fix'. Raw cacao powder can be added to smoothies without the need to use sugar, so it's the super healthy option in its least processed form.
Studies on cocoa have been shown to exert beneficial effects on cardiovascular risk by lowering blood pressure, increasing insulin sensitivity, reducing inflammation, increasing HDL (good cholesterol) decreasing LDL (bad cholesterol) oxidation and through its anti-platelet function. Research also suggests that cocoa and dark chocolate is cholesterol neutral.
A comparative study of black tea, green tea, red wine and cocoa shows that although they all high in phenols such as resveratrol, cocoa is more beneficial to health due to its higher antioxidant capacity. It is important to note that cocoa also contains caffeine so is best avoided by those suffering from high blood pressure. It also contains the obromine that stimulates the central nervous system and dilates blood vessels so eating chocolate would not be advised at meditation time.
So enjoying a cup of coffee, glass or red wine or indulging in some dark chocolate does have its health benefits; however it is important to remember that caffeine, sugar and alcohol can both negatively impact your health so should be consumed only in moderation. Fresh fruits and vegetables contain an abundance of anti-oxidants so keep your diet full of them. Organic, fresh and unprocessed as possible is always best. Enjoy!
