15 Surprising and Science-Backed Health Effects of Dark Chocolate

15 Surprising and Science-Backed Health Effects of Dark Chocolate

You have probably heard others talk about the benefits of eating foods packed with nutrients and antioxidants as a way to promote overall health. I would be willing to bet that chocolate, and more specifically dark chocolate, has come up in these conversations. While it seems almost too good to be true, the health benefits to eating a moderate amount of dark chocolate are backed by science. So rest assured, this is one instance where you can have your cake (or in this case, dark chocolate) and eat it too.

1. For centuries, dark chocolate has been long been associated with health benefits

Incas referred to a beverage made from cocoa as “the drink of the gods”, which eventually gave rise to its scientific name Theobroma cacoa, derived from the Greek words theo (god) and broma (drink). Aztec Emperor Montezuma stated that cocoa “builds up resistance and fights fatigue” and can “permit a man to walk for a whole day without food”.

2. Dark chocolate is rich in a class of phytonutrients called flavonoids

Flavonoids are one of the most common and largest groups of phytonutrients found in the diet. These phytonutrients are chemicals found in plants that promote health To date more than 4,000 varieties have been identified. Dark chocolate and cocoa contain specific flavonoids called flavan-3-ols (or flavanols).

3. Dark chocolate is chock(olate) full of other nutrients

A small bar of 70-85% dark chocolate, let’s say 50 grams/1.75 ounces, contains

  • nearly 6 grams of fiber for digestive health
  • a third of your recommended daily allowance (RDA) for iron to promote cardiovascular fitness
  • over a quarter of your RDA for magnesium for skeletal health
  • nearly 50% of your RDA for copper and manganese, important for antioxidant functions

It is also important to note, that a serving of dark chocolate contains 300 calories, so it is best to consume dark chocolate in moderation. And don’t worry! You can still get these healthy effects from smaller servings; just try to make sure you are eating dark chocolate that 70-90% cocoa.

4. Flavan-3-ols/flavonols in dark chocolate lower blood pressure

Research has shown that after consumption of dark chocolate, antioxidant capacity in blood increased, which led to the opening of blood vessels and decreased blood pressure.

5. Dark chocolate decreases “bad” cholesterol and increases “good” cholesterol levels

You may have heard LDL, HDL, or VLDL. But what does this alphabet soup mean to your cholesterol and overall health? Briefly, cholesterol is made up low-density lipoprotein (LDL), high-density lipoprotein (HDL) and very low-density lipoprotein (VLDL). LDL is considered the “bad” cholesterol that can build up on the walls of arteries, while “HDL” is called the good cholesterol, which can block LDL from building up on arteries. A variety of studies have shown that both dark chocolate and cocoa powder reduced LDL and oxidized LDL levels and increased HDL levels.

6. Dark chocolate reduces platelet aggregation

Platelets are components found in blood cells that help to form clots. While clots are critical in stopping excessive bleeding, hyperactive platelets can contribute to coronary heart disease. A study investigating the effects of white, milk, or dark chocolate showed that dark chocolate inhibited platelet accumulation, while white and milk chocolate had no effect on platelet clustering.

7. Risk for cardiovascular disease is slashed by dark chocolate

Points #4-6 may be all well and good, but does dark chocolate broadly impact hearth health? Turns out, it does. A study researching the long-term diet habits in nearly 500 elderly men revealed that cocoa intake was inversely correlated with cardiovascular disease and mortality rates that were assessed 15 years after the study began. Another epidemiological study in the US general population demonstrated that consumption of chocolate was inversely related to coronary heart disease and that eating chocolate 5 times per week lowered the coronary heart disease risk by 57%. So go ahead and enjoy a daily piece of dark chocolate.

8. Moderate dark chocolate consumption lowers the risk for stroke

What about stroke? An analysis of five different studies demonstrated a nearly 20% stroke risk reduction when comparing those defined as high consumers (~ 62.9 grams/week or a tenth of a pound for our non-metric friends out there) to those defined as low consumers of dark chocolate (~ 0 grams/week).

9. Insulin blood sugar spikes are reduced by dark chocolate

Unfortunately, diabetes is a growing concern in the United States, so wouldn’t it be great if dark chocolate could mitigate rates of diabetes? An analysis over 40 clinical trials, including nearly 1300 participants, found that nutritional interventions with cocoa or chocolate significantly reduced fasting insulin concentrations and insulin resistance, endpoints which are used to assess risk for the development of diabetes and cardiovascular disease. Again, moderation is key here and the distinction between cocoa/dark chocolate and milk/white chocolate is critical since milk/white chocolate have lower levels of healthful components.

10. Flavanols stimulate blood flow to the brain

A 450 milligram dose (about 1/6 of a teaspoon) of cocoa flavanols increased cerebral blood flow to gray matter in the brain. Additionally, a five day regimen of 150 milligrams of cocoa flavanols increased blood oxygenation levels. But does blood flow translate into smarts? I’m so glad you asked, see the next point.

11. Increasing intake of cocoa can improve cognitive function

A study in 90 elderly participants investigated the effects of a high (~990 milligrams), intermediate (~520 milligrams), or low (~45 milligrams) cocoa flavanol doses. Researchers found that participants on the high flavanol track were able to complete cognitive tests much faster and scored better on verbal fluency test scores in comparison to those assigned to low flavanol supplementation. So you are telling me that dark chocolate could make me smarter? Sweet.

12. Dark chocolate reduces stress

This list just gets better and better. Personally, I feel like a weight has been lifted off my chest and this next point only helps this feeling. Preliminary studies demonstrate that dark chocolate consumption reduced excretion of cortisol and catecholamines, hormones involved in the body’s stress response. Additionally, other researchers have shown that consumption of dark chocolate buffered stress responses and reduced levels of perceived stress as assessed through a stress questionnaire. Now it makes even more sense to keep a bar of dark chocolate at work.

13. Dark chocolate boosts energy

I am always looking for an alternative pick me up to my traditional afternoon cup of coffee. Dark chocolate contains a small amount of caffeine to help give you a boost during the mid-afternoon slump.

14. Flavanols from dark chocolate can protect the skin

Just in time for summer! Consumption of flavanol rich chocolate protects against UV rays by increasing the minimum amount of UV rays required to cause skin redness. Moreover, flavanols from cocoa improve blood flow to the skin and increases skin hydration and thickness.

15. Dark chocolate can improve teeth health

Sparkle up that smile. Dark chocolate is rich in the antioxidant theobromine, which has been shown to protect the enamel surfaces of teeth. Additionally, this potent antioxidant is better than fluoride at remineralizing and hardening tooth enamel. Knowing these facts only makes me smile more.

As you can see, the health effects of dark chocolate are supported by science and exhibit how dark chocolate and cocoa broadly promote health. Even though I am a dark chocolate lover already, reading over this list has only further convinced me to pick up another bar the next time I am grocery shopping to enjoy this treat (in moderation)!

How to Stop Procrastinating: 11 Practical Ways for Procrastinators

How to Stop Procrastinating: 11 Practical Ways for Procrastinators

You have a deadline looming. However, instead of doing your work, you are fiddling with miscellaneous things like checking email, social media, watching videos, surfing blogs and forums. You know you should be working, but you just don’t feel like doing anything.

We are all familiar with the procrastination phenomenon. When we procrastinate, we squander away our free time and put off important tasks we should be doing them till it’s too late. And when it is indeed too late, we panic and wish we got started earlier.

The chronic procrastinators I know have spent years of their life looped in this cycle. Delaying, putting off things, slacking, hiding from work, facing work only when it’s unavoidable, then repeating this loop all over again. It’s a bad habit that eats us away and prevents us from achieving greater results in life.

Don’t let procrastination take over your life. Here, I will share my personal steps on how to stop procrastinating. These 11 steps will definitely apply to you too:

1. Break Your Work into Little Steps

Part of the reason why we procrastinate is because subconsciously, we find the work too overwhelming for us. Break it down into little parts, then focus on one part at the time. If you still procrastinate on the task after breaking it down, then break it down even further. Soon, your task will be so simple that you will be thinking “gee, this is so simple that I might as well just do it now!”.

For example, I’m currently writing a new book (on How to achieve anything in life). Book writing at its full scale is an enormous project and can be overwhelming. However, when I break it down into phases such as –

Advertising

  • (1) Research
  • (2) Deciding the topic
  • (3) Creating the outline
  • (4) Drafting the content
  • (5) Writing Chapters #1 to #10,
  • (6) Revision
  • (7) etc.

Suddenly it seems very manageable. What I do then is to focus on the immediate phase and get it done to my best ability, without thinking about the other phases. When it’s done, I move on to the next.

2. Change Your Environment

Different environments have different impact on our productivity. Look at your work desk and your room. Do they make you want to work or do they make you want to snuggle and sleep? If it’s the latter, you should look into changing your workspace.

One thing to note is that an environment that makes us feel inspired before may lose its effect after a period of time. If that’s the case, then it’s time to change things around. Refer to Steps #2 and #3 of 13 Strategies To Jumpstart Your Productivity, which talks about revamping your environment and workspace.

3. Create a Detailed Timeline with Specific Deadlines

Having just 1 deadline for your work is like an invitation to procrastinate. That’s because we get the impression that we have time and keep pushing everything back, until it’s too late.

Break down your project (see tip #1), then create an overall timeline with specific deadlines for each small task. This way, you know you have to finish each task by a certain date. Your timelines must be robust, too – i.e. if you don’t finish this by today, it’s going to jeopardize everything else you have planned after that. This way it creates the urgency to act.

My goals are broken down into monthly, weekly, right down to the daily task lists, and the list is a call to action that I must accomplish this by the specified date, else my goals will be put off.

4. Eliminate Your Procrastination Pit-Stops

If you are procrastinating a little too much, maybe that’s because you make it easy to procrastinate.

Identify your browser bookmarks that take up a lot of your time and shift them into a separate folder that is less accessible. Disable the automatic notification option in your email client. Get rid of the distractions around you.

I know some people will out of the way and delete or deactivate their facebook accounts. I think it’s a little drastic and extreme as addressing procrastination is more about being conscious of our actions than counteracting via self-binding methods, but if you feel that’s what’s needed, go for it.

5. Hang out with People Who Inspire You to Take Action

I’m pretty sure if you spend just 10 minutes talking to Steve Jobs or Bill Gates, you’ll be more inspired to act than if you spent the 10 minutes doing nothing. The people we are with influence our behaviors. Of course spending time with Steve Jobs or Bill Gates every day is probably not a feasible method, but the principle applies — The Hidden Power of Every Single Person Around You

Identify the people, friends or colleagues who trigger you – most likely the go-getters and hard workers – and hang out with them more often. Soon you will inculcate their drive and spirit too.

As a personal development blogger, I “hang out” with inspiring personal development experts by reading their blogs and corresponding with them regularly via email and social media. It’s communication via new media and it works all the same.

6. Get a Buddy

Having a companion makes the whole process much more fun. Ideally, your buddy should be someone who has his/her own set of goals. Both of you will hold each other accountable to your goals and plans. While it’s not necessary for both of you to have the same goals, it’ll be even better if that’s the case, so you can learn from each other.

I have a good friend whom I talk to regularly, and we always ask each other about our goals and progress in achieving those goals. Needless to say, it spurs us to keep taking action.

7. Tell Others About Your Goals

This serves the same function as #6, on a larger scale. Tell all your friends, colleagues, acquaintances and family about your projects. Now whenever you see them, they are bound to ask you about your status on those projects.

For example, sometimes I announce my projects on The Personal Excellence Blog, Twitter and Facebook, and my readers will ask me about them on an ongoing basis. It’s a great way to keep myself accountable to my plans.

8. Seek out Someone Who Has Already Achieved the Outcome

What is it you want to accomplish here, and who are the people who have accomplished this already? Go seek them out and connect with them. Seeing living proof that your goals are very well achievable if you take action is one of the best triggers for action.

9. Re-Clarify Your Goals

If you have been procrastinating for an extended period of time, it might reflect a misalignment between what you want and what you are currently doing. Often times, we outgrow our goals as we discover more about ourselves, but we don’t change our goals to reflect that.

Get away from your work (a short vacation will be good, else just a weekend break or staycation will do too) and take some time to regroup yourself. What exactly do you want to achieve? What should you do to get there? What are the steps to take? Does your current work align with that? If not, what can you do about it?

10. Stop Over-Complicating Things

Are you waiting for a perfect time to do this? That maybe now is not the best time because of X, Y, Z reasons? Ditch that thought because there’s never a perfect time. If you keep waiting for one, you are never going to accomplish anything.

Perfectionism is one of the biggest reasons for procrastination. Read more about why perfectionist tendencies can be a bane than a boon: Why Being A Perfectionist May Not Be So Perfect.

11. Get a Grip and Just Do It

At the end, it boils down to taking action. You can do all the strategizing, planning and hypothesizing, but if you don’t take action, nothing’s going to happen. Occasionally, I get readers and clients who keep complaining about their situations but they still refuse to take action at the end of the day.

Reality check:

I have never heard anyone procrastinate their way to success before and I doubt it’s going to change in the near future.  Whatever it is you are procrastinating on, if you want to get it done, you need to get a grip on yourself and do it.
