An Ounce of Prevention is Worth a Pound of Cure

healthhabits — Wed, 20 Jan 2010 23:26:07 +0000

Mainstream Medicine may finally be catching on.

In a major shift of emphasis in the battle against cardiovascular disease, the American Heart Association is urging people to embrace prevention rather than just try to avoid risks long associated with the world’s leading killer.

.

The Dallas-based organization unveiled a list of seven steps people can take to help prevent heart attacks and strokes and live healthy lives well into old age. The recommendations, which include staying smoke-free, eating healthy foods and getting regular exercise, are all familiar.

.

But leaders hope a more pro-active message comprising the entire package of steps will help blunt the impact of the obesity epidemic and build on four decades of progress against the ravages of cardiovascular disease.

“We’ve always looked at this from the risk side of the equation,” said Donald Lloyd-Jones, head of preventive medicine at Northwestern University’s Feinberg School of Medicine, Chicago. “It’s important to push the agenda of promoting health, not just avoiding disease.”

Dr. Lloyd-Jones is lead author of a scientific statement being published in the AHA journal Circulation describing the science behind the strategy. The paper doesn’t break any new ground on heart-disease risk. Indeed, in addition to the steps on smoking, diet and exercise, the report urges people to control cholesterol, blood pressure, blood sugar and a measure of healthy weight called body mass index.

.

Each of the recommendations has long been at the foundation of heart-disease prevention, but Dr. Lloyd-Jones says their impact taken as a whole hasn’t previously been appreciated.

By attaining goals in all seven steps, Dr. Lloyd-Jones said, people would achieve “ideal” cardiovascular health with a likelihood of living healthy lives well into old age.

Together, they amount to “a fountain of youth for the heart.”

.

So, here’s my question….

.

How do we get from telling to doing?

.

There is a big difference between knowing that you should do something and actually doing it.

And, while education about disease prevention / health promotion is important, it still doesn’t get many big ole butts up off the sofa.

Did You Take Your Vitamin D This Morning?

healthhabits — Fri, 20 Nov 2009 02:51:17 +0000

Winter is on the way people.

And along with the frigid temperatures and slushy sidewalks, winter means less sunshine.

And less sunshine means less Vitamin D.

And, according to this study, less Vitamin D means you have an increased risk of stroke, heart disease and death.

The Study

For more than a year, the Intermountain Medical Center research team followed 27,686 patients who were 50 years of age or older with no prior history of cardiovascular disease. The participants had their blood Vitamin D levels tested during routine clinical care. The patients were divided into three groups based on their Vitamin D levels – normal (over 30 nanograms per milliliter), low (15-30 ng/ml), or very low (less than 15 ng/ml). The patients were then followed to see if they developed some form of heart disease.

Researchers found that patients with very low levels of Vitamin D were 77 percent more likely to die, 45 percent more likely to develop coronary artery disease, and 78 percent were more likely to have a stroke than patients with normal levels. Patients with very low levels of Vitamin D were also twice as likely to develop heart failure than those with normal Vitamin D levels.

The researchers concluded “that among patients 50 years of age or older, even a moderate deficiency of Vitamin D levels was associated with developing coronary artery disease, heart failure, stroke, and death,” she says. “This is important because Vitamin D deficiency is easily treated.

If increasing levels of Vitamin D can decrease some risk associated with these cardiovascular diseases, it could have a significant public health impact. When you consider that cardiovascular disease is the leading cause of death in America, you understand how this research can help improve the length and quality of people’s lives.”

So, did you take your Vitamin D today?

What does Healthy Look Like?

healthhabits — Thu, 19 Nov 2009 19:48:53 +0000

According to research out of the UK, the color of a person’s skin affects how healthy and therefore how attractive they appear.

And since the color of a person’s skin is directly influenced by the quality of their diet, the researchers concluded that your diet may be crucial to achieving the most desirable complexion and therefore maximizing your attractiveness.

So, it’s true…you are what you eat.

Or, in this case, you’re as attractive as you eat.

Note - Researchers were looking exclusively at Caucasian test subjects. The research was not concerned with racially differentiated skin colors.

The Study

Using specialist computer software, a total of 54 Caucasian participants of both sexes were asked to manipulate the skin color of male and female Caucasian faces to make them look as healthy as possible. They chose to increase the rosiness, yellowness and brightness of the skin.

“Most previous work on faces has focused on the shape of the face or the texture of the skin, but one of the most variable characteristics of the face is skin color,” said Dr. Ian Stephen who is now at the University of Bristol.

“We knew from our previous work that people who have more blood and more oxygen color in their skins looked healthy, and so we decided to see what other colors affect health perceptions.

Skin that is slightly flushed with blood and full of oxygen suggests a strong heart and lungs, supporting the study’s findings that rosier skin appeared healthy. Smokers and people with diabetes or heart disease have fewer blood vessels in their skin, and so skin would appear less rosy.

.

The preference for more golden or ‘yellow-toned’ skin as healthier might be explained by the ‘carotenoid pigments’ that we get from the fruit and vegetables in our diet. These plant pigments are powerful antioxidants that soak up dangerous compounds produced when the body combats disease. They are also important for our immune and reproductive systems and may help prevent cancer.

.

.

They are the same dietary pigments that brightly colored birds and fish use to show off their healthiness and attract mates, and the researchers think that similar biological mechanisms may be at work in humans.

“In the West we often think that sun tanning is the best way to improve the color of your skin,” said Ian Stephen, “but our research suggests that living a healthy lifestyle with a good diet might actually be better.”

Melanin, the pigment that causes the tan color when skin is exposed to the sun makes the skin darker and more yellow, but participants in the study chose to make skin lighter and more yellow to make it look healthier.

Conclusion

Beauty = Health

And until all of us start carrying our health records around with us, we will have to rely on our ancient “lizard brains” to determine if another person looks healthy and therefore attractive.

Researchers Find the Answer to Senior Citizen Heart Health

DR — Mon, 26 Oct 2009 17:13:13 +0000

Researchers have discovered a cutting edge technique to help senior citizens improve the elasticity of their arteries – thereby reducing their risk of heart disease and stroke.

Led by Dr. Kenneth Madden, the researchers were able to reduce arterial stiffness by 15 to 20% in only 3 months time.

But wait, it gets better.

Unlike most cardiovascular treatments, the cost of this new cure-all is…….nothing, zero, nada, rien…it’s free.

It’s free because the treatment is:

Exercise

Wow!!!

Exercise instead of drugs…who would have thought of that???

The Study

Dr. Madden divided his test subjects into two groups.

The first group performed one hour of vigorous physical activity for one hour, three times a week for three months.
The second group continued to live a sedentary lifestyle.

Subjects were classified as sedentary at the beginning of the study but gradually increased their fitness levels until they were working at 70 per cent of their maximum heart rate, using treadmills and cycling machines. They were supervised by a certified exercise trainer.

And after three months, the exercise group was healthier, while the sedentary group wasn’t.

So, as a public service to all of my 65+ readers (and those readers with friends & family who are 65+), I will be posting “no equipment necessary” workouts geared toward trainees who are boomer age and older.

Enjoy

BTW, this post is for my Dad…who should be outside right now getting some exercise

Vinegar is a Fat-Burning, Waist Shrinking, Cholesterol Lowering Superfood

DR — Thu, 15 Oct 2009 16:28:42 +0000

In yesterday’s post, I introduced you to a study which showed that plain ole’ vinegar is effective in suppressing body fat accumulation.

More specifically, the researchers found that laboratory mice fed a high-fat diet and given acetic acid developed significantly less body fat (up to 10 percent less) than other mice.

I was so excited by this low-tech, inexpensive weight loss trick that I contacted the author of the study.

And to my surprise, he emailed an even more recent study which looks at the fat-burning effects of vinegar on actual human beings….no more mice studies.

The Science

In this study, researchers investigated the effects of vinegar intake on the reduction of body-fat mass in obese Japanese students.

The 175 students were randomly assigned to three groups of similar body-weight, BMI and waist circumference.

During the 12 week study, the participants ingested 500ml daily of a beverage containing either 15 ml of apple vinegar (750 mg AcOH – acetic acid), 30 ml of vinegar (1500 mg AcOH) or 0 ml of vinegar (0 mg AcOH, placebo).

In place of vinegar, the placebo group ingested 1250 mg of lactate.

To make them more palatable, all beverages contained the equal amount of flavor and artificial sweetener.

The Results

After only 4 weeks, the vinegar-group participants saw their body-weight, BMI and body-fat percentages improve. These improvements continued in a dose dependent manner for the entire 12 weeks

Translation: more vinegar = more fat loss

In addition to BF, BMI and BF%, waist circumference, waist-hip ratio, LDL cholesterol and serum TG (triglyceride) levels also fell (starting in week 8).

These results can be considered to be due to the body-fat loss because the VFA (visceral fat), SFA (subcutaneous fat) and TFA (total fat) values were significantly lower in the vinegar groups than in the placebo group.

Does the vinegar make these "diet" chips?

Conclusion

15 ml (0.5 oz or 1 tbsp) of vinegar per day is enough to significantly improve your:

Body-Weight
BMI
Body-Fat Percentage
Waist Circumference
Waist-Hip ratio
LDL Cholesterol
Serum TG
Visceral Body-Fat, and
Subcutaneous Body-Fat

And considering that these health markers are associated with type 2 diabetes, heart disease, stroke and metabolic syndrome, perhaps it might be wise to consider adding a tbsp or two of vinegar to your daily diet.

Your Omega 3 Prescription

DR — Fri, 04 Sep 2009 18:27:41 +0000

By this point, you should already know that you need more Omega 3 fatty acids into your diet.

The question is: how much?

A teaspoon of fish oils?
A tablespoon?
3 pills?
or a great big slab of smoked salmon?

Well, according to this study, researchers believe that “a 200 mg dose of DHA per day is enough to affect biochemical markers that reliably predict cardiovascular problems, such as those related to aging, atherosclerosis, and diabetes”.

This study is the first to identify how much DHA is necessary to promote optimal heart health.

The Study

To determine the optimal dose of DHA, the researchers examined the effects of increasing doses of DHA on 12 healthy male volunteers between ages of 53 and 65. These men consumed doses of DHA at 200, 400, 800, and 1600 mg per day for two weeks for each dose amount, with DHA being the only omega-3 fatty acid in their diet. (No EPA)

Blood and urine samples were collected before and after each dose and at eight weeks after DHA supplementation stopped. The researchers then examined these samples for biochemical markers indicating the effects of each dose on the volunteers.

They found that supplementation with only 200 mg/d DHA for 2 wk induced an antioxidanteffect.

They concluded that “low consumption of DHA could bean effective and nonpharmacological way to protect healthy menfrom platelet-related cardiovascular events”.

Conclusion

If this study is correct, you need only 200 mg of DHA per day to reap the cardiovascular benefits of the Omega 3 fatty acid DHA.

And how do you get 200 mg of DHA?

1/2 tsp of fish oil
2 of these kiddie chewable DHA supplements
5 Krill capsules
2 oz of fresh/frozen salmon or tuna

OxyCholesterol…the most serious cardiovascular health threat of all?

DR — Mon, 31 Aug 2009 16:34:51 +0000

Researchers have found that a (virtually unknown to the public) form of cholesterol called oxycholesterol may be your most serious cardiovascular health threat.

“Total cholesterol, low-density lipoprotein cholesterol (LDL), and the heart-healthy high-density lipoprotein cholesterol (HDL) are still important health issues,” says study leader Zhen-Yu Chen, Ph.D., of Chinese University of Hong Kong. “But the public should recognize that oxycholesterol is also important and cannot be ignored.

Our work demonstrated that oxycholesterol boosts total cholesterol levels and promotes atherosclerosis ["hardening of the arteries"] more than non-oxidized cholesterol.”

Q. So, how do we get this oxidized cholesterol – oxycholesterol?

A. Fried food, processed food, junk food…basically all of the food that makes you fat also has high levels of oxycholesterol. Quel surprise.

Scientists have known for years that a reaction between fats and oxygen, a process termed oxidation, produces oxycholesterol in the body.

Oxidation occurs, for instance, when fat-containing foods are heated, as in frying chicken or grilling burgers or steaks.

Food manufacturers produce oxycholesterol intentionally in the form of oxidized oils such as trans-fatty acids and partially-hydrogenated vegetable oils. When added to processed foods, those substances improve texture, taste and stability.

Until now, however, much of the research focused on oxycholesterol’s effects in damaging cells, DNA, and its biochemical effects in contributing to atherosclerosis. Dr. Chen believes this is one of the first studies on oxycholesterol’s effects in raising blood cholesterol levels compared to non-oxidized cholesterol.

In the new study, researchers compared the effects of a oxycholesterol rich diet to a diet rich in regular non-oxidized cholesterol.

The oxycholesterol group showed greater deposition of cholesterol in the lining of their arteries and a tendency to develop larger deposits of cholesterol. These fatty deposits, called atherosclerotic plaques, increase the risk for heart attack and stroke.

More importantly, oxycholesterol had undesirable effects on “artery function.”

Oxycholesterol reduced the elasticity of arteries, impairing their ability to expand and carry more blood.

In a healthy, elastic artery, expansion allows for more blood to flow through arteries that are partially blocked by plaques, potentially reducing the risk that a clot will form and cause a heart attack or stroke.

Luckily, a healthy diet rich in antioxidants can counter these effects, Chen said, noting that these substances may block the oxidation process that forms oxycholesterol.

Scientists do not know whether the popular anti-cholesterol drugs called statins lower oxycholesterol.

And how do we get a diet rich in antioxidants?

Fruits, vegetables, nuts, seeds, herbs and spices….aka real food.

SuperFood: Beet Root

DR — Fri, 07 Aug 2009 18:24:15 +0000

An interesting new study shows that drinking beet root juice boosts your stamina and could help you exercise for up to 16% longer.

The theory is that the nitrate contained in beet root juice leads to a reduction in oxygen uptake, making exercise less tiring.

And while the researchers are not yet sure of the exact mechanism that causes the nitrate in the beet root juice to boost stamina, they suspect it could be a result of the nitrate turning into nitric oxide in the body, reducing the oxygen cost of exercise.

In fact, drinking beet root juice reduces oxygen uptake and improves endurance better than any other known means, including training.

Including training!

Obviously, this is big news for endurance athletes.

The Science

The researchers gave the test subjects 500ml per day of organic beet root juice for six consecutive days before completing a series of tests, involving cycling on an exercise bike.

On another occasion, they were given a placebo of blackcurrant cordial for six consecutive days before completing the same cycling tests.

After drinking beet root juice the group was able to cycle for an average of 11.25 minutes, which is 92 seconds longer than when they were given the placebo.

Beet root supplementation resulted in a 19% reduction in the amplitude of the pulmonary O2 response during moderate cardio exercise

As an extra added bonus, the group that had consumed the beet root juice also had lower resting blood pressure. (systolic pressure dropped 6 mmHg)

This blood pressure benefit was also found in a 2008 study.

In that study, researchers discovered that within 1 hour of drinking 500ml of beet root juice, volunteers experienced a drop in blood pressure, with the peak drop 3 to 4 hours after ingestion.

Some degree of reduction continued to be observed until up to 24 hours after ingestion.

Researchers showed that the decrease in blood pressure was due to the chemical formation of nitrite from the dietary nitrate in the juice. The nitrate in the juice is converted in saliva, by bacteria on the tongue, into nitrite. This nitrite-containing saliva is swallowed, and in the acidic environment of the stomach is either converted into nitric oxide or re-enters the circulation as nitrite.

The peak time of reduction in blood pressure correlated with the appearance and peak levels of nitrite in the circulation, an effect that was absent in a second group of volunteers who refrained from swallowing their saliva during, and for 3 hours following, beet root ingestion.

This research suggests that drinking beet root juice, or consuming other nitrate-rich vegetables, might be a simple, effective and inexpensive way to reduce blood pressure and maintain a healthy cardiovascular system.

Conclusion

If you are interested in:

Lowering your blood pressure
Reducing your risk of heart disease
Increasing your aerobic endurance
and making you cardio sessions feel much, much easier

Drink your beet juice.

And if you can’t get your hands on some fresh beet root juice, there are a number of GreenFood/SuperFood/Antioxidant drinks that have beet root powder as an ingredient.

High Carb Diet = Heart Attack

DR — Tue, 30 Jun 2009 12:14:04 +0000

IHOPs Butterscotch Rocks Pancake....mmmmmm distended brachial arteries

For the first time in medical history, researchers have been able to visualize what happens inside our arteries before, during and after eating high carb foods.

And it ain’t a pretty sight.

Looking inside the arteries of students eating a variety of foods, Dr. Michael Shechter ( Tel Aviv University) visualized exactly what happens inside the body when the wrong foods for a healthy heart are eaten.

He found that foods with a high glycemic index resulted in distended brachial arteries for several hours.

Dr. Shechter continues:

Elasticity of arteries anywhere in the body can be a measure of heart health.

But when aggravated over time, a sudden expansion of the artery wall can cause a number of negative health effects, including reduced elasticity, which can cause heart disease or sudden death.

So, let’s recap:

High GI foods (bread, sugar, desserts, pop, pizza, cereal, 99% of the food sold at any fast food restaurant…) leads to distended brachial arteries which can lead to heart attacks which can lead to death.

The Science

Using 56 healthy volunteers, the researchers looked at four groups.

Group One ate a cornflake mush mixed with milk,

Group Two ate a pure sugar mixture,

Group Three ate bran flakes,

Group Four was given a placebo (water).

Over four weeks, Dr. Shechter applied his method of “brachial reactive testing” to each group. The test uses a cuff on the arm, like those used to measure blood pressure, which can visualize arterial function in real time.

The results were dramatic. Before any of the patients ate, arterial function was essentially the same. After eating, except for the placebo group, all had reduced functioning.

Enormous peaks indicating arterial stress were found in the high glycemic index groups: the cornflakes and sugar group.

“We knew high glycemic foods were bad for the heart. Now we have a mechanism that shows how,” says Dr. Shechter. “Foods like cornflakes, white bread, french fries, and sweetened soda all put undue stress on our arteries.

We’ve explained for the first time how high glycemic carbs can affect the progression of heart disease.”

During the consumption of foods high in sugar, there appears to be a temporary and sudden dysfunction in the endothelial walls of the arteries.

Endothelial health can be traced back to almost every disorder and disease in the body.

It is “the riskiest of the risk factors,” says Dr. Shechter.

So how come my doctor tells me to eat cereal for breakfast?
