Exercise can make your body feel younger. . . and (maybe) actually make it younger?

IMG_8348rt5x7bwAs we prepare for Thanksgiving (and in my case, the Thanksgiving Day Turkey Trot!) there is some good news on exercise and aging.  We know that lifelong regular exercise can reverse many of the effects of aging – at least in “elite” or professional lifelong athletes. But what about “regular people” who commit to a lifestyle of regular activity? Can their bodies become “younger” too?

A recent study (link to full study here) tried to answer this question – by studying the Running Turkeybodies (specifically, muscle tissue) of older individuals who had remained active though regular leisurely activities. The main findings, according to this article in the New York Times summarizing the study:

“The muscles of the older exercisers resembled those of the young people, with as many capillaries and enzymes as theirs, and far more than in the muscles of the sedentary elderly.

The active elderly group did have lower aerobic capacities than the young people, but their capacities were about 40 percent higher than those of their inactive peers.

In fact, when the researchers compared the active older people’s aerobic capacities to those of established data about “normal” capacities at different ages, they calculated that the aged, active group had the cardiovascular health of people 30 years younger than themselves.”

What does this mean?

  1. Committing to an active lifestyle can slow, or even eliminate” many of the changes in our muscles that we consider “normal aging”
  2. Even though our overall exercise capacity does diminish over age, these changes are slowed significantly in those who remain active, compared to less active older individuals.
  3. In the words of one of the researchers, “exercise could help us to build a reserve of good health now that might enable us to slow or evade physical frailty later”

So this is more evidence for all of us to stay active – here is our overview of physical activity and its benefits on heart health, and here are more articles on exercise:

Omega-3’s? Vitamin D? Vitamins? Which can prevent heart disease?

IMG_8348rt5x7bwWith heart disease continuing to be a leading cause of death throughout the world, researchers continue to look at how diet, supplements and other habits can impact the development of heart disease. Here is a rundown of some new studies that continue to shed light on how to prevent (or in some cases, not prevent) heart disease:

As most doctors have suspected for a while, vitamin D seems to have minimal effect on your heart and circulation system. This new study seems to confirm that fact.  Certainly, people with a severe deficiency should have replacement therapy, but routine use does not appear to have a significant preventive benefit.

The news with multivitamins is similar. We have suspected this for a while (see our prior article on the role of supplements) but now a large study on thousands of patients (in this case, limited to men) seems to confirm that routine multivitamin use really does not prevent future heart disease. This does not exclude other benefits, but reinforces our recommendation that multivitamins are probably not needed for those with a well-rounded diet.

How about fish oil? Here is a link to a nice updated article addressing which patients may benefit from omega-3 fatty acids. Despite high hopes, no studies have really shown a broad benefit to most healthy adults. But those with specific conditions may benefit.

These studies reinforce the Heart Health Doctors’ dietary advice – eat a balanced diet low in processed foods, unnecessary carbs (especially wheat-based) and saturated fats, and watch the total calories. As always, you should consult with your health provider about what specific diet is best for your health, and your medical conditions.

Here are our earlier articles on diet, supplements and heart disease:

Heart Health and Type 1 Diabetes

 

Diabetes plays such a role in heart disease that it is considered not only a risk factor but a coronary artery disease equivalent. Women who experience gestational diabetes have increased heart risk throughout their adult life. There a multiple presentations and forms of diabetes but broadly can be considered type 1 and type 2.

Fewer people have Type 1 Diabetes compared with Type 2 Diabetes, however in general Type 1 can present at much younger ages. I was diagnosed with type 1 diabetes at age 20 (also called “Juvenile diabetes” I was insulted to be diagnosed when I was no longer a juvenile – only to learn that the ‘juvenile’ terminology was no longer accurate, and yes, I did have T1D).

Recommendations for heart health and using lifestyle to reduce risk for heart disease applies if you have diabetes – and is even more important.

Heart Health and Type 1 Diabetes is a post for the organization Beyond Type 1 that outlines heart health and Type 1 Diabetes. Heart Health Docs followers will recognize a lot of the content and emphasis on heart healthy choices including the American Heart Association Life’s Simple 7

Take a few minutes this Labor Day weekend to check out The Beyond Type 1 website  ~ an excellent source of information covering nutrition, health, and stress management for anyone looking to improve their health, and is a great place to learn about type 1 diabetes specifically.

 

 

Diet and Heart Disease – What Does the Science Say About What to Eat?

IMG_8348rt5x7bwIt is so hard to keep up with research on diet and disease prevention, especially with so many conflicting reports in the media. To try to sort through this, some researchers looked comprehensively at all of the high quality research available about diet and prevention of heart disease. They put together this nice summary table showing which foods show evidence of harm, which show evidence of benefit, and which are inconclusive.
It is important to remember that this is addressing heart disease specifically, not general health or general disease prevention.  And they limited their conclusions to the most thorough studies of heart disease outcomes.  For example, I think a diet which is low in wheat-based carbohydrates can be very beneficial for maintaining weight and preventing long-term health complications.
If you, or a family member, suffers from chronic heart disease, this table is a good starting point for a discussion with your physician and other health providers about the optimal diet to prevent future heart issues.

You Really Are (and might die from) What You Eat (. . .or Don’t Eat)!

IMG_8348rt5x7bwMost of us understand that there is a link between what we eat and our health – but how strong, and how important, is that connection? Heart and circulatory disease is the number one killer of American adults, and we know that certain dietary behaviors can either promote, or reduce, health consequences.

But a new study  just released, shows just how strong that association is between diet and heart disease. These researchers looked at all of the important studies of specific food types and disease associations, then compared this to national surveys of Americans’ eating habits. They then estimated what proportion was due these various dietary habits.

Overeating, or not eating enough, of the 10 foods and nutrients contributes to nearly half of U.S. deaths from heart and circulatory disease, the study suggests.bread

“Good” foods that were under-eaten include: nuts and seeds, seafood rich in omega-3 fats including salmon and sardines; fruits and vegetables; and whole grains.

“Bad” foods or nutrients that were over-eaten include salt and salty foods; processed meats including bacon, bologna and hot dogs; red meat including steaks and hamburgers; and sugary drinks.

Of course, this was a study of populations, and most of us are most concerned about our personal habits and risk of disease (remember, only your doctor or health care provider can give your specific advice about your health care). And most importantly, the fact that certain dietary habits are “associated” with bad health, doesn’t mean those foods “cause” bad health.   But this is an interesting study that helps quantify the most important targets for change in our diet.  (click here to read  the full study)

#GoRedCbus ~ When should you learn about Heart Failure?

BW ARA labcoatThe American Heart Association’s Go Red for Women event February 23, 2017 gave Columbus information about Heart Health for Women, and provided opportunity to support AHA in advocacy, research, and education.

Left – right, JS, Dr. Albers, Dr. Basuray

Dr Anup Basuray (photo) presented a breakout session on a complex topic. The name Heart Failure does not in fact mean a heart has stopped working (my engineer/math husband is one of many who question the name Heart Failure – but this has been and remains our wording). The term is broad covering symptoms that occur when the heart is not fully functioning – leading to symptoms including shortness of breath, leg swelling, abdominal swelling, fatigue, and/or weight gain or loss. In his presentation, Prevent. Treat. Recover. : Transforming Heart Failure into a Success Story Dr. Basuray highlighted examples of young women patients he has treated. His case presentations illustrated the different ways people get heart failure; some specific to women, for example in the case of problems associated with pregnancy.

Heart Failure is diverse in cause, outcomes, and treatment. The slide here shows ~ 10 causes of Heart Failure, more recently identified is history of cancer treatment, and also included is ‘unknown‘ or doctor-speak, idiopathic. Heart valve disease, genetics (inherited causes), high blood pressure, drugs and alcohol, infection, coronary artery disease, pregnancy related, and irregular heart rate/rhythm can all be causes of Heart Failure.

Heart Failure results in fluid retention by the kidneys, a problem that is worse with high sodium diet. Western diets have high sodium – top sources are Breads and rolls, cold cuts and cured meats, pizza, poultry, soups, sandwiches, cheese, pasta dishes, meat dishes, SNACKS. Reading labels and being aware of sodium is key to heart health in general and to limiting fluid retention in Heart Failure in particular. Knowledge is power when considering what we eat – see here https://hearthealthdocs.com/heart-healthy-diet/  , and for surprising sources of salt https://hearthealthdocs.com/2016/06/08/surprise-sources-of-salt-in-your-diet/

Dr. Basuray addressed the power of prevention and how to stay healthy by knowing the following KEY modifiable risk factors for heart failure

  • High blood pressure
  • Diabetes
  • Obesity
  • High cholesterol

Know your numbers

  • Blood pressure, cholesterol, diabetes (blood glucose) screen
  • Every 4-6 years, as early as age 20

2013 AHA/ACC Heart Failure Guidelines 

So when should you learn about Heart Failure? Now is good. Same with choosing to live a heart healthier life.

Who Benefits from Fish, or Fish Oil? Some New Info on the Link to Heart Disease

IMG_8348rt5x7bwWhile we have known for some time about the potential benefits of fish in the diet, the specific role of supplements containing the beneficial component, omega-3 fatty acids, has been less clear, due to inconsistent results from various studies.

Fortunately, a new study released this month has clarified the link between supplementation with omega-3 fatty acids and the development of heart disease. This was actually a meta-analysis, meaning it summarized the data from multiple previous studies, in a manner that yields more information than the individual studies themselves. This was a very thorough analysis, specifically looking at the best quality studies (called randomized trials), and specifically looking at the useful component of omega-3 fatty acids, EPA and DHA. Moreover, the researchers were focused specifically on heart and circulatory complications.

What did they find? The intake of omega-3 fatty acids, either from food or supplements,fish-oil reduced the risk of heart disease by 6%. This reduction is mild, and was actually insignificant, but there was a significant decrease specifically patients who started out with high triglyceride levels (> 150 mg/dL) or LDL cholesterol (> 130 mg/dL). When the researchers included additional nonrandomized studies, the reduction in heart disease was 18%. Another important conclusion was that there does not appear to be any harmful effect of supplementation.

So what can we conclude?
First, supplementation with 1 g of omega-3 fatty acids daily, either from food or supplements, appears to be mildly beneficial in preventing heart and circulatory disease.
Second, the majority of the benefit is in patients who start out with elevation of triglyceride or LDL cholesterol. Previous studies (such as this) have shown that otherwise healthy patients derive minimal or no benefit from fish oil supplementation.
Third, there does not appear to be evidence of harm at this level of supplementation.

Also of note, more detailed studies are ongoing to determine the optimal level of supplementation and specific patients. Finally, keep in mind that there are other potential benefits of fish oil supplementation unrelated to heart disease, so if supplementation makes you feel better or healthier, it may be reasonable.  As always you should discuss your specific health situation with your doctor before considering any supplement or other therapy.
