Oregano, Grapes and Cancer – Oh my!

With November here, most people are aware that “Movember” is also in full swing, promoting prostate cancer research, among other things. What isn’t so common knowledge is the fact that two rather yummy research endeavours are showing promise in the field of prostate cancer treatment.

Already well known for being an antioxidant, oregano was used in one study to test its effects on prostate cancer cells. Researchers tested carvacrol, a component of oregano, in varying concentrations against human prostate cancer cells for different time intervals. Amazingly, they discovered that the carvacrol completely wiped out the cancer cells!

From their research, the team found out that the carvacrol actually caused apoptosis, or ‘cell suicide’, in the cancer cells. It is still in its beginning stages but “if the study continues to yield positive results, this super-spice may represent a very promising therapy for patients with prostate cancer,” says Dr. Bavadekar, the lead researcher. Watch here as the SourceFed team talks about this new research:

The next study looks into the effects of a compound found in red wine and grape skin on prostate cancer cells. Previous studies have shown that this compound, resveratrol, may have health benefits concerning heart health and stroke prevention. In this study, researchers found that the compound caused the prostate cancer cells to be more vulnerable to radiation. Watch here as the MU News Bureau talks to the researchers about their discovery:

The resveratrol causes the cancer cells to express two proteins, perforin and granzyme B, which work together to cause the cell to weaken. When combined with radiation, more cancer cells were killed than with just radiation alone.

The drawback to this discovery is that the body metabolizes resveratrol very efficiently. This means that a very high dosage would need to be consumed in order for the compound to be effective at the tumour site. Due to this, researchers are looking into alternate delivery methods, as the treatment is otherwise promising.

I believe that both of these studies show a lot of potential and are particularly interesting because the compounds used are naturally occurring. It makes me wonder about all the other naturally occurring treatments that may still be out there. Who knows, maybe the next promising cancer treatment will be from pomegranates or blueberries!

New Car Smell

I’ve always loved the smell of a brand new car.  I personally associate the smell with success and happiness, in my opinion buying a new car is a big milestone and accomplishment.  Unfortunately, there are several hundred different chemicals used in the production of a vehicle’s parts creating the “new car smell.”

 

A new study from the Ecology Centre in Ann Arbor, Michigan, found more than 275 chemicals in 200 new cars.  A majority of the chemicals are found in upholstered areas of a vehicle, including the steering wheel, armrest, seats and dashboards.  The chemicals create toxic gases and fumes within vehicles that consumers inhale and associate with the “new car smell.”

The main chemicals found in new cars are Brominated Flame Retardants (BFRs), and metals such as chromium, and lead.  BFRs are a mixture of chemicals found in the plastic and fabric components of a vehicle’s interior.  BFRs are known to cause breast cancer, and thyroid hormone problems that are linked to brain and body development.  The combination of the chemicals and toxins has devastating consequences; they include birth defects, impaired learning, and liver issues.

A key question that arises to my mind is do all cars have the same amount of chemicals and toxic levels in their interiors?  Interestingly, out of the 200 examined cars, the 2012 Honda Civic has the healthiest interior and contained the least dangerous chemicals.  It was found to have no BFRs and minimum metals.  The worst vehicle was the 2011 Mitsubishi Outlander Sport and the 2011 Chrysler 200 SC.  These two vehicles have high levels of BFRs in their seats and other chemicals in the upholstery.

 

Overall, I believe it is important to consider the levels of dangerous chemicals when purchasing a new vehicle because as a consumer you will be spending large periods of time in your new vehicle and need to be aware of the potential dangers in the vapors you breathe.  Remember to buy a car based on its quality and minimum use of chemicals, not based on its smell.

Is Genetically-Modified Food Safe?

Genetcially modified foods (GMF) surround our daily lives. The vegetables and fruits at grocery stores, and the meat that  can be bought at a deli are all, at some point, attributed to the enhancement of genetics. What does it mean to be genetically modified? At a molecular level, the genetic make-up of an organism is either altered by insertion or deletion of specific segments of a gene, which results in different phenotypic traits. These traits exhibit better resistance to harsh weather conditions, resilience to insect infestations, and they are easier to grow across all conditions.

So what are some advantages to GMF? The biggest advantages are production cost and efficiency. GMF is cheap to produce and easy to grow. An example of this is corn. Thousands of tons of corn are produced each year, and about 82% of the corn on the market are genetically modified. Other advantages include pest resistance, disease resistance, drought tolerance, and salinity tolerance.

Fig.1 This is an example of what a genetically modified corn can look like. There are different colors located on different beads of corn.

As for disadvantages, there really hasn’t been any real implications or diseases associated with GMF in humans. In Canada, GMF are treated like any other food, and there are no specific laws that push for companies to label their products as genetically-modified. Though there hasn’t been human related health hazard cases, a study done in France on rats showed rats that were fed genetically-modified corn died prematurely, and tumors developed in the liver, kidney, and skin.

Fig.2 Rats that ate genetically-modified corn from Monsanto exhibited tumor growths around the body. These growths eventually lead to the death of the subjects prematurely.

So should consumers like ourselves trust the ongoing development of GMF? As of yet, there hasn’t been any concrete evidence to support that GMF can cause tumor growths, cancer, or any serious health issues in humans; however, there is a correlation between them. Presently, I think it is safe to consume GMF, but with a regulated diet including organic foods. In addition, I believe that  governments should push for stronger regulations and tighter laws that govern the production and distribution of GMF.
