Wine: Is it really a toast to good health, and a healthy heart?

IMG_8348rt5x7bwYou may have seen recent articles in the media such as this that seem to contradict the notion that regular wine intake can be heart healthy. So this may be a good time to explore the link between wine intake and heart disease in more detail. For several decades, we have known that certain populations in the world, such as France, seems to have less heart disease despite a higher intake of saturated fats. One explanation for this finding (referred to as the “French paradox”) was the high intake of red wine in these populations, leading to speculation that red wine could somehow prevent heart disease. In fact, many studies have shown that so-called “moderate” alcoholic intake (one drink a day for women, or 2 or less for men) seems to lead to less chronic disease and a longer life span than those who drink heavily, or not at all.  Of course these are only observational (e.g. not randomized) studies, so there is always controversy about whether other factors could also play a role.

eca284793cc89e389f347e0f41da895aAlthough wine contains many heart-protective antioxidants, the agent which was postulated to be particularly protective is resveratrol, as animal studies have shown that high doses of this antioxidant can prevent chronic disease.  Although the studies were not really applicable to humans (due to extremely high doses of resveratrol), this led to the widespread notion that red wine is particularly “heart healthy”. Unfortunately, no other studies have been able to show that any particular agent in red wine makes it superior to other types of alcohol in the prevention of chronic disease. The new study released last week confirms this, as these researchers measured the amount of resveratrol in elderly Spaniards, to confirm their consumption of red wine.  They found no relationship between wine consumption and longevity, heart disease, or cancer.

So, what can we conclude about wine intake and heart disease?  First of all, you should ask your doctor about how alcohol could interact with your specific health conditions and overall risk profile.   Here are some other key points backed by the evidence:

1. Moderate alcohol use, as defined above, does seem to have a protective effect against chronic disease and increased longevity, compared to heavy drinkers or nondrinkers.

2. However, no specific type of alcohol, including wine, has clearly been shown to be superior in terms of its protective effect. Certainly, wine (red or white), with less alcohol and more antioxidants then other types of alcohol, would seem to be a reasonable choice for those who choose to drink alcohol.

3. Because the protective effect of alcohol has not been shown conclusively, there is not enough evidence to recommend that someone initiate regular alcohol use simply for the health benefits. Other lifestyle issues, such as a healthy diet, regular exercise, and weight maintenance are far more important.

4. In very detailed studies, there does not seem to be any specific elevated risk associated with mild or moderate alcohol use. Therefore those of us who incorporate alcohol into our lifestyle should focus on the quantity we drink, and making it part of a overall healthy lifestyle.

5. Increasing use beyond “moderate” can clearly increase the risk of complications and chronic illness.

So if you decide to incorporate alcohol into your lifestyle, do so for your enjoyment, not necessarily for your health – and always in moderation! And for more specific advice, check with your doctor.

Exercise – A Great Way to Multitask for Heart Health @CapCityHalf @OhioHealth

BW ARA labcoatEight thousand two hundred fifty three runners completed Saturday’s 11th Cap City Half marathon, in addition to participants in the Patron Quarter Marathon and Commit to Be Fit 5K events.  It was a great event for Ohio.  The HeartHealth Doctors have posted information about heart function and exercise.  Exercise such as running can be the ultimate way to multitask for heart health by managing stress, getting to or keeping goal weight, improving cholesterol profile, and reducing high blood pressure. Exercise has been shown to impact diabetes risk and can assist diabetes management.  Research shows being more active is key to heart health; walking is an excellent way to exercise.  Walking 10 minutes twice daily gets you close to the recommended guidelines for physical activity (150 minutes per week of moderate (means heart rate increases, but you can have a conversation)).

The American College of Cardiology’s Cardiosmart resource has great information about how to Move More. Being active directly impacts numerous risk factors for heart disease.

Heart Health professionals are responding to the evidence of heart health benefits of exercise and athletics.  Sports Cardiology is a section of the American College of Cardiology and provides an area for Cardiovascular Specialists (doctors who treat heart and vascular disease) to help people be active.  Someone wanting to be active could be a professional athlete, a young person, someone who participated in sports at school and now wants to return to competition, or patients who have completed cardiac rehabilitation programs and want to continue to develop their exercise regimen with the goal of improving their heart health.  The membership in the Sports Cardiology section of the American College of Cardiology has grown from 150 in 2011 to > 4000 members.  Cardiologists are working to promote the benefits of exercise, balanced with modifying/reducing risks athletes may face.

The half marathon run May 3 had an Ohio feel to it; weather ranging from cool temperature, warmer temperature, intermittent grey skies, intermittent rain, some sunshine.  There were great crowds, creative signs for encouragement, good music from bands, DJ’s, and the help of many many volunteers.  It was a well run event (!) and sets the stage for the U.S.A. Men’s and Women’s National Half Marathon Championships coming to Cap City in 2016, 2017.  You don’t have to be a national champion runner to get benefit from exercise; use a tracker to check your steps (> 22,000 yesterday!), or commit to someone (or a group) who want/s to be more active.  Yesterday ~11,955 total event participants at the Cap City Half / Patron Quarter Marathon / Commit to Be Fit 5K – did great heart health multitasking.
