Barley Grass

What is Barley Grass?

People often confuse barley grass with wheatgrass, but these are two very different plants. Barley grass is one of the earliest grown sweet grasses. The ancient Egyptians used barley grass to feed both their people and their animals.

The ancient Romans and Greeks used the grass to make barley bread for their athletes. They believed the bread boosted energy and strength.

Barley grass is now making a resurgence, as more people are focusing on living healthier lives and eating real, whole foods.

Barley grass is a nutritional powerhouse, rich in vitamins A, C, E, K, B1, B2, B3, B5 and B12. It also contains folic acid, beta carotene, pantothenic acid, iron, calcium, magnesium, potassium, phosphorus, and sodium. And like other healthy grasses, barley contains enzymes, amino acids, protein, chlorophyll and fiber.

Thanks to all of these nutrients, barley offers a number of health benefits, including:

An Immune System Boost

Barley grass contains copper, iron, folic acid, and vitamins C, B12 and B6 – all of which help boost the immune system.

Barley actually has five times more iron than spinach. Iron helps prevent fatigue and anemia while improving blood volume. Vitamin C improves the body’s resistance to infection and disease.


Barley grass is rich in antioxidants, which help fight free radical damage. Along with beta-carotene and vitamin E, barley grass is one of the best sources of the enzyme superoxide dismutase.

Superoxide dismutase neutralizes the effects of free radicals produced during metabolism. Oxidative stress has been linked to an array of diseases, and the antioxidants in barley grass can help provide some protection from these diseases.


Even if you eat a healthy diet, you’re exposed to toxins in your environment which can build up over time. Barley grass can help with metal chelation, ridding the body of toxic heavy metals.

The plant can also help eliminate waste materials, including mucus and crystalized acids. The chlorophyll in the plant helps provide oxygen and improve blood flow. These actions help in the removal of harmful toxins and impurities from the body.

Weight Loss

Barley grass can help jumpstart your weight loss. The plant is a source of insoluble fiber, which helps you feel fuller for longer. It also provides an array of nutrients that your body needs to thrive. At the same time, barley grass helps keep blood sugar levels under control to prevent those intense cravings in between meals.

Helping Type 2 Diabetes

Studies have shown that barley grass can actually help lower blood sugar levels and improve insulin resistance.

Barley grass contains beta-glucan, which is a soluble fiber that slows down the absorption of glucose.

Reduces Cholesterol

In one clinical study on the effects of barley grass on type 2 diabetes, researchers found that in addition to lowering blood sugar levels, the plant also helped lower cholesterol.

After 70 days of consuming barley grass daily, cholesterol levels of participants fell by 5.1%.

5 Unusual Health Benefits of Cannabidiol Oil

CBD Oil Health Benefits

CBD, THC’s calm cousin, is known for its anti-anxiety and pain-relieving effects, but this cannabinoid may also offer other health benefits.

From inflammation to weight loss and clear skin, CBD oil can have some surprising effects on the body.



Here are five unusual health benefits of cannabidiol oil.

1. Anti-Inflammatory Effects

Inflammation is believed to contribute to at least seven of the 10 leading causes of death, including cancer, heart disease, stroke, diabetes and Alzheimer’s disease.

A study published in the Journal of Experimental Medicine found that CBD reduced pain and chronic inflammation in some mice.

Cannabinoids exert their anti-inflammatory effects through inhibition of cell proliferation, induction of apoptosis (death of cells), induction of T-regulatory cells (Tregs) and suppression of cytokine production.

Cytokines are secreted from cells as a response to injury and infection in the body.

2. Overcome Addiction

There is some evidence that CBD can help people quit smoking and overcome other addictions.

In one study, published in Addictive Behaviors, smokers who used CBD-infused inhalers smoked fewer cigarettes and no longer had cravings for nicotine.

CBD has also been shown to reduce withdrawal symptoms in those suffering from substance abuse, including insomnia, pain, anxiety and mood-related symptoms (source CBDAlliance.org). It is believed that CBD modulates the neuronal circuits involved in drug addiction.

3. Weight Management and Diabetes

When it comes to weight management, CBD may help users stay on the right track. CBD affects the body’s metabolism, helping you maintain a healthy weight with greater ease.

In one study, published in Molecular and Cellular Biochemistry, CBD was shown to induce fat browning, improve the oxidation and breakdown of fat, decrease fat cell generation, and increase the body’s ability to burn calories.

Some researchers believe that CBD may have the potential to treat type 2 diabetes and cardiovascular disease due to its anti-inflammatory properties.

In one study, scientists found that cannabidiol prevented diabetes in young mice. Just 30% of the mice treated with CBD developed diabetes, while 86% of non-treated mice developed the disease.

It is believed that CBD may prevent and delay the destruction of insulin-producing cells in the pancreas, according to one mouse study. CBD may also reduce inflammatory cytokines in diabetic mice by changing the immune response.

4. Anti-Psychotic Properties

Unlike THC, CBD actually has anti-psychotic properties and may even reduce symptoms in schizophrenia.

Research suggests that CBD may be a natural alternative to anti-psychotic drugs, but with fewer side effects.

In one study involving 42 patients with acute schizophrenia, CBD (800 mg daily) improved all symptoms after four weeks.

5. Anti-Acne Properties

Acne is caused, in part, by inflammation and also be overworked sebaceous glands. CBD’s anti-inflammatory effects may help reduce breakouts, but it can also help keep your skin clear in other ways.

One study published in the Journal of Clinical Investigation found that CBD lowers sebum production. The reduced sebum production is due partly to the anti-inflammatory effects of CBD.

CBD benefits the body in many ways, both physically and mentally. But it’s important to ensure that you’re using high-quality CBD from a reputable brand to maximize its benefits.



Ancestry DNA Testing

Your pre-historical ancestry is buried in your DNA.

Leading anthropologists have turned to DNA because they can learn about the past by studying the present in DNA from people around the world. Now you can order the same DNA tests that have revolutionized the study of human history and embark on your own personal expedition of genetic discovery.

Individualized Testing Reports

Scientists study populations of people. The reports that come with your DNA tests explain what the results mean to you as an individual. What’s more important, they’re written in language you can understand.

Our Common Male Ancestor Test and Common Female Ancestor Test include a summary of what scientists have learned about the geographical origin and age of your maternal and paternal lines based on your DNA test results.

Our Ethnicity DNA Test provides a global overview of your genetic makeup telling you what percentage of your DNA is shared with Africans, Europeans, Asians and Native Americans. If the Ethnicity DNA testing shows that you have enough European ancestry to proceed, our European Ethnicity DNA Test will further breakdown your European heritage into Northern European, Mediterranean, Middle Eastern, and South Asian. Our Native American verification testing can confirm if you are of Native American descent.

Complete, Customized Testing Services

The complete battery of tests available online let you pick and choose to customize your own personal genetic “dig.”  From your own unique personality traits to understanding how to boost brain performance.

Here are some of the things you can find out by DNA testing.

  • Africans Were your ancestors from the Forest Dwellers (pygmies) or !Kung, the oldest existing human populations at more than 100,000 years? Or were they part of the Bantu expansion out of Central Africa? Markers largely confined to specific tribes, such as the Ibo, early merchants and travelers, may be discovered.


  • Europeans Do you have ancestors from the original hunter-gatherers of Europe or were they among the farmers who migrated from the Middle East? All Europeans are descended from seven maternal clans as outlined in The Seven Daughters of Eve by DNA researcher Brian Sykes. Which are you from? Do you have markers that are largely confined to specific areas of Europe, such as Sardinia or the Basque region?


  • Native Americans Four clans dominate the ancestry of Native Americans and each is associated with specific language groups and are thought to be evidence for the different waves of migration that originally populated the new world. Possession of one of these markers is some of the best genetic evidence available for demonstrating Native American Ancestry.


  • Genealogists Do you have a common last name such as Smith and are trying to track down other Smith’s that descend from the same male ancestor? Do you think you have found a removed cousin and want to confirm that you have the same great-great-great-great grandmother?

Deciding Which Family Members to Test

Testing of all individuals in a family is not necessary. Men have both mtDNA and Y DNA. Women have only mtDNA because Y is the sex determining gene and is present in males only. For example, a brother and sister will have the same mtDNA and brothers the same Y DNA. Test results apply to everyone in a given male or female lineage. Please call for help in deciding who to test in order to get a complete set of results for your family. Reporting of results will be based on the family tree that you submit when ordering your tests.

Limitations of testing.

Test results are statistical probabilities of your origins and must be interpreted with caution. Human populations have been mixing since they began leaving Africa more than 100,000 years ago. A genetic marker can strongly suggest an origin, but is not 100% proof because no markers have so far been found that exist exclusively in a single group. If all the available tests are run on any given individual that still represents only a small percent of their total DNA.

Although you may be predominantly from one of the main human population groups, the markers you discover in yourself can be from other groups because of the extensive mixing of human populations. Scientists believe that we’re all descended from fewer than 100,000 individuals and that we’re all related! The person sitting next to you, if they’re not your parent, child, sibling, uncle or aunt, then most likely they’re a distant cousin.


At Home DNA Test 101

At Home DNA Test Kit

“Where do I come from?  Where am I going?”

These questions are foundational to the human experience.  Where your ancestry and health are concerned, it is now easier than ever before to get answers thanks to the development of at home DNA test kits.

You have probably seen these test kits advertised on television and online, and may be wondering whether they are worth it.

Are they accurate?  Are they easy to use?  Can they help you protect your health? 

In this article, I am going to answer those questions so that you can make an informed choice.  First, I will tell you all about at home DNA test kits: how they work, what they can tell you, and what their limitations are.

Then I will tell you about my favourite at home DNA testing company and the kits I recommend for health and well-being.  Let’s dive in.

What Are Home DNA Test Kits?

To some, the concept of an at home DNA test may seem obvious.  But for others, it might not.  I know the first time I heard about it, it seemed like something out of a science fiction movie.

The idea couldn’t be simpler.

You order a test kit online.  It is shipped to you in the mail.  You take a sample and send it back.

There’s nothing technical about it—at least not on your end.  The technical stuff all happens at the lab.  You just kick back and wait for your results.

There are a number of popular brands which are offering affordable at home DNA test kits right now.  A lot of them are geared toward helping you uncover your ancestry.

The test kit I’m going to suggest is for something even more important: helping you take care of your health.

DNA test kits for health fill a gaping void when it comes to healthcare, and that is providing you with the building blocks for a customized plan for wellness.

That means you can say goodbye to one-size-fits-all diet and weight loss plans, and you can take steps now to protect yourself from diseases which you may be genetically predisposed to.  That is the power of DNA.


How The Home DNA Testing Process Works

Let’s talk a little bit more about the process.  It varies from company to company, but for HomeDNA Testing, the company I recommend, it works like this:

  1. You order your test kit through the HomeDNA store online. You can do this in the comfort of your own home on your desktop, laptop or mobile device.
  2. You register your kit in order to activate it. This step is also done online.
  3. Wait for your DNA test kit to arrive in the mail.
  4. When the test kit arrives, open it up and read the instructions carefully.
  5. Collect your DNA samples. You do this by taking cheek swabs. There are no needles involved, which means zero pain.
  6. Mail back the samples.
  7. The lab will check out your DNA against thousands of markers. This process takes around 4-6 weeks. During this time, you also will need to fill out a short survey to describe your health and lifestyle goals.
  8. The company will email you a report. In it, you can learn about your genetic profile. You also will be given personalized recommendations for health and lifestyle based on your genes.  How cool is that?

That’s all there is to it!  It could not be easier or faster to learn about your unique makeup.


What Are the Advantages of Home DNA Test Kits Over Traditional DNA Tests?

There are three major benefits to at home DNA testing:

  • Cost
  • Convenience
  • Privacy

According to the National Institutes of Health, DNA tests can range in price anywhere from $100 to $2,000, sometimes even higher.

Traditionally, it was common to have to pay thousands of dollars if you wanted to get your DNA tested at a hospital or clinic.

It has only been over the past few years that DNA tests have become affordable to the average consumer.

By getting your DNA tested at home, you can save hundreds, maybe even thousands of dollars.

Getting your DNA tested at home also spares you the hassle of getting in your car, driving to a clinic or testing center, and waiting to get your samples taken.

In fact, the entire process at home is close to effortless.  Instead of taking hours, it takes only minutes.

Plus, if for whatever reason you want to be discreet about your test, you can.  Nobody but you has to know that you are delving into your DNA.

Are There Any Limitations to Home DNA Tests?

On the whole, if you are making a casual inquiry into your DNA, I would say that at home testing makes a lot more sense than going to a clinic.  You will save a ton of time and money.

The two main limitations I can identify are these:

  • Accuracy issues (depending on the company and the method)
  • Lack of counseling

Not all DNA companies use the same techniques to draw conclusions from your DNA.  Some are using outmoded methods.  In fact, even some at home DNA testing companies have pointed out the challenges in providing consumers with accurate results.

That is why it is so important to make sure that you are using a company which is at the cutting edge in the field and is performing analysis in line with the latest research.

It is also helpful to keep in mind that accuracy issues can happen if you go the traditional route with testing as well.

The other limitation of at home DNA testing is that you are given your results in a report, but you do not have a licensed doctor on hand to explain them to you or put them in context.

If you are anxiety-prone, you might assume a certain marker means you will get a certain disease.

But let’s try to remember Gattaca.  While that movie was a work of fiction, its message was relevant. Probabilities do not always equal realities.

Keep that in mind when you get your report, and if you do have concerns, get in touch with your healthcare provider.

What Features Should You Shop For in a High Quality Home DNA Test Kit?

Now you know both the benefits and limitations of at home DNA test kits.  So long as you choose a quality company, you can keep inaccuracies to a minimum and enjoy the cost savings and other great benefits.

Here is what to look for to ensure that you are getting a quality test from a trusted brand:

  • Choose a company which conducts its analysis in labs which are CAP-accredited and CLIA-certified.
  • Analysis should be conducted according to the most up-to-date research.  You should deal with a company which is constantly refining its techniques for the highest possible accuracy.
  • The actual test kit should be manufactured in compliance with FDA regulations.
  • Check the privacy policy with care.  Make sure that your information will never be shared with or sold to third parties without your explicit permission.
  • Pick a company which will cater to your needs.  If you want detailed health recommendations for example, it doesn’t make sense to get a kit which only looks at your ancestry.  Make sure that you will actually get a personalized report, not something generic.
  • A price you can afford.  Most DNA test kits cost $200 or less, so it should be relatively easy to find more than a few reasonably priced options.  For that reason, I suggest you focus mainly on features and benefits.
  • Customer service.  If at any point you have a question or concern and need a fast response, you will want to be working with a team that has you covered.

What is the Best Home DNA Test Kit for Health?

best home dna test kit
I’ve ordered DNA test kits from a number of brands now, so I have had plenty of opportunity to cross-compare features, pros and cons.

By far, I have had the best experiences with HomeDNA.

Here is what I love about this company:

  • HomeDNA offers a variety of DNA tests for different purposes, mainly focused on health.
  • The HomeDNA lab is the DNA Diagnostics Center (DCC®).  This laboratory has been in operation since 1995, and has processed more than a million samples.  You may have heard of them.  Celebrities like Anna Nicole Smith and Prince have used them, and they’ve been featured on TV.  All research and analysis is conducted by PhDs.
  • You can order a HomeDNA test kit online or pick it up at a store near your location.
  • Shipping on HomeDNA test kits is free.  That includes the postage when you mail in your samples.
  • The company has outstanding customer service.  Other companies I ordered from didn’t bother telling me when they’d received my samples.  HomeDNA emailed me right away when they got mine.  They also emailed me when the results of the analysis were available in my online account.
  • HomeDNA has a very strict privacy policy.  They promise to never sell your information to third parties.  Even more impressive, they destroy your samples once they are finished with the analysis.  Other companies keep them.

There are three HomeDNA tests which I recommend for health:

  • GPS Origins Advanced Ancestry Report
  • HomeDNA™ Healthy Weight
  • HomeDNA™ Skin Care

The Healthy Weight test is aimed at those who are struggling to lose or maintain weight based on “one-size-fits-all” diets.  Based on your genotype, the lab will compile a report which gives you specific suggestions for your diet and workouts in order to optimize weight loss.

The Skin Care test assesses collagen, elasticity, pigmentation, sensitivity, and other areas of skin health based on your genetics.  This allows you to make educated decisions in purchasing supplements, topical ointments and other skincare treatments which will best fit your skin profile.

These are both awesome products if you are just interested in those specific areas of health.  But my top recommendation by far is the company’s flagship test kit, Vitagene® Health Report + Ancestry.

When You Order Vitagene® Health Report + Ancestry, Here Is What You Get:

  • An all-in-one test for ancestry and health.  The lab will examine over 700,000 genetic markers.  That is a lot of data.  You’ll be given a full breakdown of your genetic heritage by region.
  • An in-depth diet report.  You will be given a customized food plan which you can follow to mitigate obesity risk, gluten sensitivity, lactose sensitivity and more.  Your personalized diet will help you control cholesterol and triglycerides to prevent cardiovascular disease.
  • A personalized exercise program.  Based on your physiology as well as your answers to the questionnaire, this program will help you optimize the intensity and frequency of your workouts to maximize your gains and achieve your goals.  It will also direct you toward different types of exercise which may suit your body.
  • A customized supplement report.  Ever wonder exactly which nutritional supplements you should be taking to maximize your health?  Finally the guessing game can end.  Your report will tell you which supplements are most important given your genetic profile.

I’ve ordered test kits from other companies that promised me “customized plans” but gave me little more than “eat fruits and vegetables.”

When I ordered Vitagene® Health Report + Ancestry, I was blown away by the level of detail in the reports. 

I love how this company has taken the leading edge of nutritional research in anti-aging supplements nd matched it up with individual genotypes and tailored it to the lifestyles and goals of customers.

Since receiving my report, I’ve made major adjustments to my diet, started a new exercise program, and switched out several of my supplements.

I can’t even tell you the difference it has made in my life. 

I’m feeling physically better than I have in ages.  The renewed energy, the weight I’ve finally dropped on the scale, and my falling triglycerides have been amazing.

But that isn’t all.  I’ve saved money on healthcare products I didn’t really need to be buying, and I’ve gotten away from diets and workout programs that were never going to work for me.

I am so much less stressed.  The peace of mind is a huge deal.  I feel like I am finally able to take care of my body and mind in a way that is uniquely right for me.

Where Can You Order Vitagene® Health Report + Ancestry from HomeDNA?

Knowledge is power, and the truth you learn from your genes can revolutionize your life.  It’s time to take control of your diet, exercise and supplements, and finally get on track toward your health and wellness goals.  Ready to take the next steps and get your own personalized Vitagene® Health and Ancestry Report?
