Heart Disease and Your Immune System

Our immune system plays a crucial role in maintaining our quality of life. Whether in prevention of common colds and flus, or supporting our longevity through consistent resilience, it’s importance is widespread.

Our intestinal system is one of the most integral parts of our immune system. Host to immune cells and lymph nodes it is also a primary site for nutrient absorption. The bacteria balance in our intestinal system is crucial to overcoming microbes or viruses we are exposed to, but also for maintaining healthy cholesterol levels.

The link to cardiovascular health & risk factors for heart disease:

Probiotics are the healthy bacteria in our gut (and in several foods). They create an acid which signals the liver to cease cholesterol production (yes, we naturally manufacture it…it’s not just in foods). Probiotics also breakdown cholesterol, using it for nourishment. If this isn’t enough reason to pay attention to your gut (literally and figuratively!), probiotics also breakdown bile acids produced in the liver. This is significant because the liver makes bile (used in fat digestion)…from cholesterol. Therefore when probiotics breakdown bile, the liver needs to manufacture more, and thus uses up excess cholesterol. Excess cholesterol is a biomarker for heart disease.

Probiotics become depleted, and our intestinal flora imbalanced when we consume sugary foods, refined flour/grains, drink chlorinated water, are over stressed, have poor digestion, and from antibiotic use (the effects of which can linger for months or years!).

How does our immune system become compromised?

  • Poor quality sleep (remember: it’s quality over quantity)
  • Too much stress
  • Over training
  • Poor quality nutrition

Having been sick for two weeks now, I really feel confronted with the reality of imbalance. A whirlwind of germ exposure at a trade show, inconsistent sleep & work piled up (aka stress). Add on a couple of hard workouts, a few nights of drinking, and overindulging in sugar, and you have a recipe for disaster. I shouldn’t be surprised! Just a “safe” self reminder, I am not invincible. It’s reminders like this that cement good habits for me. Listen to the signals your body sends you!

I really have to focus on the health of my immune system so I can sustain my busy (and rewarding!) lifestyle...

I really have to focus on the health of my immune system so I can sustain my busy (and rewarding!) lifestyle…

I really believe it’s less about the germs you are exposed to, than the condition of your immune system. If your immune system is suppressed or compromised, you’re more likely to get sick…not the more germs you are exposed to.

From trial and error, and research, here’s how I recommend re-setting and supporting your immune system:

Clean up your diet: Refined flours, sugars, artificial food ingredients and any foods your highly sensitive to just don’t belong. They are neither necessary or nourishing.

Support your sleep: Get black out shades or use an eye mask, white noise machines (or use an app) if you live in a noisy space; change your sheets and tidy your bedroom. Set the scene for a restful night. You may also want to try these yoga poses 15-20 minutes before bed.

Choose not to take things personally, and always try your best: These two simple practices can help you let stress roll off your back, and feel confident that you did everything you could, even if things don’t always turn out.

Consume plenty of chlorophyll, antioxidants and essential fats: You may choose to supplement the diet, or emphasize these on your grocery list.

  • Chlorophyll is the green pigment in plants and aside from being rich in vitamins and minerals, it supports red blood cell production by increasing blood volume. Chlorophyll mimiks the structure of red blood cells, but has a central magnesium ion instead of iron. Eat chlorophyll (green) foods with iron rich foods like nuts & seeds.
  • Focus on eating a wide variety of fruits and vegetables. As a general rule of thumb, the richer the pigment, the higher the antioxidant value. Athletes should consider an additional antioxidant supplement.
  • Foods high in essential fats can be found in my recommended grocery list coming in a post later this week.

For the active crowd:

Train smarter, not harder: Instead of focusing on maximizing the hours spent sweating it out, focus on impactful training sessions and ample recovery time and nutrients to rebuild the best quality muscles for cardio or strength performance. Impactful training could mean working with a coach or trainer who will customize your workout, cross training & adding variety to your workouts, interval training (cardio), and techniques such as back to back sets, or compound exercises for strength training.

Eat plant based & nutrient dense foods 24 hours before & after a tough workout: Building on the above, this is important to reducing inflammation, maximizing your energy & accelerating recovery. Any athlete will know the importance of these three performance gains…

You are what you eat! Here’s to health.

Imbibe This: A Nutritionist Evaluates the Drinking Dilemma

Could your doctor soon be handing over a prescription indicating: “drink more”? Recently released by the University of Calgary, an analysis of over 84 studies on the relationship of alcohol consumption and cardiovascular disease, would like us to believe so. I’ve decided to share the natural nutritionists side to the modern day drinkers dilemma.

http://topnews.in/healthcare/sites/default/files/red-wine.jpg

I recently headed out with my Mum, visiting from Canada, for a wine tasting in the Yarra Valley. This coincided with a rather timely e-update to my inbox from theheartwire.org indicating “Light to moderate drinking: Likely cardioprotective, but recommended?” You might also agree that this isn’t the first time you’ve heard a little vino here and there has been popularly accepted as a heart healthy choice. However being that one of my principles includes not accepting here-say, rather researching and applying my nutritionist’s perspective to heart health focus topics, dictated my need to delve further into the debate.

Dr. Paul Ronksley and Dr. Susan Brien’s meta analysis concluded that one drink per day for women and two for men has shown to increase HDL Cholesterol (the good one!), and decrease biomarkers for cardiovascular disease and strokes such as fibrinogen levels. The increase in HDL Cholesterol levels was shown to be greater than any currently available individual pharmacological therapy.

The study followed drinkers and non-drinkers without pre-existing cardiovascular disease, with an average of 11 years of follow up across the 84 studies evaluated. The effects were independent of whether alcohol was consumed in beer, wine, or liquor.

“…Alcohol, in moderation, may have overall health benefits that outweigh the risks in selected subsets of patients” says Dr. William Ghali (senior author of the analysis). However, the results of this analysis has massive implications for administering the advice to potential candidates of therapeutic alcohol consumption.

Dr. Ghali adds, “The strategy for counseling patients would have to be evaluated in pragmatic clinical trials that assess the questions of optimal patient selection, compliance, risks, and benefits.” Such considerations would need to include: family (heart) health history, family history of alcoholism, predisposition to mental health imbalance or addiction, age, current drinking habits etc…

Please note: it’s not all “drink up” advice. While the analysis I have reviewed here includes positive support for the incorporation of a drink or two a day in individuals with no contraindications, there does exist a flip side. Take for example, a study from the University of California that indicates the correlation between alcohol consumption and arrhythmias (irregular heart beats, heart flutters etc…). This study noted an increased risk with an increase in alcohol intake. Those particularly prone included binge drinkers.

“Even at the recommended one to two drinks per day, there was an increased and significant risk for atrial flutter. While alcohol in limited amounts is known to be cardioprotective, many patients with atrial fibrillation might be under the impression that they should be drinking one or two drinks per day.” Dr. Gregory Marcus (University of California) indicates.

Advocating a more widely accepted, less contested method of reducing cardiovascular disease through means such as diet and exercise is far more likely to gain widespread appeal, than the recommendation to drink more. Particularly when alcohol provides no nutritional benefit, being “empty calories”. We also can’t simply ignore the effect of alcohol on additional body systems such as our liver. Already typically overburdened with its role in detoxification and breaking down excess hormones and cholesterol.

My take? If we look at the preparation of alcohol, we know all alcohol is subject to some form of fermentation via fibrin (a fibrous organic matter), gluten (wheat), casein (an enzyme found in dairy), egg whites or yeast. This fermentation, while typically in the presence of sugar and high heat, does mimic the beneficial fermentation of probiotic rich foods such as yogurt, kefir, pickled vegetables such as sauerkraut, tempeh and miso.

Fermenting wine @ fieldstonewine.com

Probiotics, such as those in the previously mentioned food sources have been shown to reduce cholesterol by breaking down bile in the colon, inhibiting its re-absorption into the blood. Probiotics can also help to reduce inflammation in the body, which can also decrease your cardiovascular disease risk.

Is there a connection between heart healthy probiotics and the fermentation in alcohol? Of this I can only speculate. However, if I was to find an alcohol made from whole grains, and/or without the use of refined sugars in the fermentation, which was heated at low temperatures during the distillation, and has no added preservatives…I might be easily convinced. Do you know of one?!

If was to place my faith in any aspect of this debate; it would be in the celebratory enjoyment of a good quality drink for those who have no current pre-disposition to addiction, arythmia, or mental health disorders. If you find yourself in this category…Cheers!

Myth Busting: Is Green Tea as Good as We’ve Heard?

Since becoming a Nutritionist, I’ve vowed not to believe hearsay and research health claims for myself before accepting their validity. As I had often heard time and again how good green tea is for our health, I decided to research it for myself. However…the more I dug around for what I thought would be studies of overwhelming support, the more conflicting information I found, and less sure I became. Is the famed health drink a fallacy?

www.ideal-living.com/wp-content/uploads/2009/05/green-tea.jpg

Survey Says:

Studies have (so far) not been able to prove a link between regular green tea consumption and a decreased risk for cardiovascular disease (CVD), and high blood pressure. While some studies have recorded as much as a 40-50% decrease in markers for CVD, others have produced no correlation to green tea and a reduced risk. **See footnotes for references.

What we do know however…

From it’s chemical make up, we know green tea is chock full of flavonoids. Flavonoids have been witnessed to scavenge the body for free radicals. Free radicals are the nasty unstable molecules that de-stabilize other cells in your body in order to stabilize themselves. Selfish! This is why free radicals are often associated with premature aging. Polyphenols (the parent category to flavonoids), can also help promote the death of irregular cells and inhibit the growth of mutated cells (hence the benefits to cancer prevention).

In lab studies, when the flavonoids found in green tea were added directly to LDL cholesterol, they helped to prevent oxidation (the destabilization produced by free radicals). While LDL cholesterol is known to be the “bad” cholesterol, it’s not “bad” until it’s been oxidized. Therefore, we need to work on keeping the oxidation process, and free radical formation low in order to help prevent the development of cardiovascular risk factors. For more information on this process please visit the following article by Dr. Stephen Stiteler: http://www.my-health-and-wellness-coach.com/cholesterol-levels.html

Wait a minute!

This suggests the potential for green tea to dramatically impact the health of our cells. So why have so many studies not been able to prove the positive connection? The common thread in the research suggests that there have been too many variables to accurately assess if green tea alone is the magic elixir. Variables such as tea quality, strength, and variety; and lifestyle factors such as diet, smoking and exercise have all been associated with affecting the results (favorably or not). This suggests we need to look at green tea in combination with other factors that could create some of the benefits we’ve believed in for so long.

Drinking Green Tea as part of a Hearty Lifestyle:

  • Often habitual tea drinkers will not be as dependent on coffee for stimulation, and may therefore have reduced stress on their adrenal glands. Stress of any kind produces excess of the hormone cortisol in the body, which promotes inflammation. Try: Swapping a few of your habitual coffee’s each week for a green tea (or even start with a green tea latte!). You can add a splash of 100% apple juice to lightly sweeten it.
  • Green tea is anti microbial and anti viral and can help to improve your immunity and your intestinal flora balance, which benefits your nutrient absorption. Try: Incorporating green tea into your day as you would a multi vitamin!
  • Green tea is the least processed tea leaf, being steamed rather than oxidized (as black tea is). Try: Making the swap if black tea is your stand by favorite, or bring green tea into rotation. Green tea also has the highest flavonoid content of all the teas (at 25-30%).
  • Of the popular caffeinated beverages available, green tea is the least caffeinated. Green tea will therefore help hydrate you as opposed to use more water in its assimilation. Being hydrated improves your body’s natural inflammation response, boosts immunity and helps balance blood pressure. Try: counting a cup of green tea as part of your daily water intake and see if you end up drinking more water than usual in a day!
  • Japanese culture uses traditional tea ceremonies as a means of practicing spiritual release, serenity, harmony and peace. There are even whole sections of homes, and yards devoted to serving tea, specifically to be able to use it as a form of meditation and unwind. It’s also traditionally used as a means to honor and respect guests. Try: Unwinding after a stressful with a green tea rather than a sweet treat. Share it with those you care about as a way to slow down and enjoy each others company.

This Holiday Season:

Let’s take a note from traditional societies and incorporate such a symbolic and vitality promoting ingredient into our own celebrations. Give the gift of tea; unwind with friends and family over tea; have a tea party to celebrate the holidays instead of a cocktail party (why not?!); or use it in your holiday baking as a means to create some festive colors and get people talking about this dynamic ingredient….

Coming later this month: Creative ways to incorporate green tea into your diet…
