GMO’s, or genetically modified organisms, have been a hot topic since the early 2000s. A GMO is an organism that has been modified or changed through genetic engineering. In food and crop science, it is common to take a gene from another organism, be it a plant, bacteria, virus, or animal and insert it into another organism to increase its usefulness in the food industry. There are many examples of the benefits of GMO crops, for example; scientists have developed tomatoes that resist frost or freezing temperatures by inserting a gene from a coldwater fish. So they may call that a tomato, but I call that a toCODo. While the FDA has deemed these products safe, many people argue that there are negative consequences to this practice. Anti- GMO activists tend to point to these negative consequences of genetic engineering in the food industry.GMO’s are unhealthy- studies point to organ damage, gastrointestinal and immune system disorders, accelerated aging, and infertility.
Studies in the US continue to fuel both sides of the debate. In Europe it is a different story though. In the early 2000s, the European Union, sought to ban the growing and cultivation of all GMO crops and products. 19 countries in total agreed to this ban including Germany, France, and Italy. Here is a map of the countries that have banned GMO crops. As a result of this ban, food scientists in Europe have been very cautious with their research. This has caused a debate surrounding the definition of the term GMO. More specifically, do new gene editing practices fall under the ban established by the EU? For example, a Swedish scientist developed a type of genetically modified weed that grows slower than the common variety of weeds (Read more about it here). This is accomplished using a new safer method of genetic engineering called CRISPR. CRISPR has been scientifically proven to increase precision, efficiency, and flexibility of genetic engineering. Many food scientists believe that this method is much safer and more reliable than older GMO practices because of its ability to make smaller edits to the genome. As a result, plants and organisms altered through CRISPR do not have any foreign or unrelated DNA.
If CRISPR is ruled legal, than researchers, like the Swedish scientists mentioned above, will receive increased funding, as well as, marketability for their solutions. Proponents of CRISPR believe that since the method results in an organism that contains no foreign DNA, than it should not fall under the EU’s ban. Others still point to the dangers of genetic engineering. The EU still has not ruled on CRISPR, so scientists in Europe continue to walk the legal research line. At Ham Farms, science is not our best subject, so we don’t mess with GMO’s. You can rest assured that all of our delicsious are 100% natural and harvested straight from the Earth.
Nearly half of the top ten oldest people living today are from Japan. In fact, Japanese men and women are more likely to reach 100 years old than any other demographic in the world today. For years, researchers have tried to figure out their secret and finally data is starting to point heavily in one direction. Most of this research is centered on an island 400 miles off the coast of Japan. Okinawa has a steady population of 1.3 million people mostly because of their extended life expectancy. Not only do the people in Okinawa live longer, but they actually age incredibly well too. Take a look at these facts;
So what’s their secret? Researchers have studied many factors that may contribute to this longevity trend. These studies tend to focus heavily on the Nature vs. Nurture discussion. Meaning, some findings suggest that the Okinawans have a natural ability to live longer and others suggest it is a product of environmental factors.
The nature debate tends to focus on their genetic makeup. They found that Okinawans have a genetic makeup that helps prevent inflammatory and autoimmune disease. I am not trying to argue that this is not a factor, but when Okinawans move to new environments they have a propensity to lose their longevity. This makes me believe that the Nurture side of the debate may have more of a positive correlation than their genetic makeup.
The Okinawa lifestyle and diet are the two main environmental factors that researchers focus on. In terms of lifestyle factors, Okinawans tend to be happier than the rest of the world. When tested, researchers found that they were generally stress-free and maintained a positive outlook on life. They also generally have strong coping skills and a deep sense of purpose. These factors have been correlated to a decrease in dementia and Alzheimer’s as well as a longer life.
Recent unearthed evidence credits their diet as the major factor in this longevity trend. American Gerontologist Dr. Craig Willcox outlines the benefits of the Okinawan diet in his book The Okinawa Program;
"The Okinawans have a low risk of arteriosclerosis and stomach cancer, a very low risk of hormone dependent cancers, such as breast and prostate cancer. They eat three servings of fish a week, on average….. plenty of whole grains, vegetables and soy products too, more tofu and more konbu seaweed than anyone else in the world as well as squid and octopus, which are rich in taurine – that could lower cholesterol and blood pressure."
Don’t like squid, octopus, or seaweed? Well there is good news for you. One of Okinawa’s main indigenous vegetables is the sweet potato. Their indigenous sweet potatoes are rich in flavenoids, carotenoids, vitamin E and lycopene.
Flavenoids- Have both antioxidant and anti-inflammatory effects, reducing the risk of heart disease especially atherosclerosis.
Carotenoids- Offer protection against certain cancers, macular degeneration, cataracts, and other free radical damaging conditions.
Vitamin E- Plays a strong role in developing a strong immunity as well as healthy skin and eyes.
Lycopene- Prevents heart disease and cancer, especially cancer of the prostate, breast, lung, bladder, ovaries, colon and pancreas.
As a result of the makeup of the sweet potato, many scientists, like Dr. Willcox, point to the sweet potato as the dietary factor that contributes heavily to longevity. Okinawans, on average, eat over a pound of sweet potatoes each week. In fact Dr. Willcox pointed out that on Okinawa, “It’s not an ice cream truck that visits your street, it’s the sweet potato truck….. and Okinawans love purple sweet potato ice cream.”
Unfortunately, there is no fountain of youth or magic medicine that makes you live longer. Food is medicine and Okinawans have mastered the longevity diet. I find it very interesting that the genetic component of the debate corresponds directly to the benefits of eating sweet potatoes. Studies have proven that Okinawans’ ability to combat heart disease, stroke, and cancer can be attributed both to their genetic makeup, as well as, their diet consisting heavily of sweet potatoes. However, when a native Okinawan moves to a new environment this advantage diminishes or disappears altogether. This fact makes me believe that their diet plays a bigger role in their longevity than their genetics. Luckily, here in North Carolina we have plenty of sweet potatoes, so if you want to live a long healthy life, eat up.
My wife asked me to Netflix and Chill the other night. Now, before everyone gets ahead of themselves, for married folk that means debating about what to watch for an hour and falling asleep halfway through the movie. My wife loves Matt Damon. Luckily, my wife has never met him, and so we ended up watching The Martian. To give you a brief synopsis- he is an astronaut/botanist in the not so distant future who gets left on Mars and survives over a year by growing his own white potato crop. Since I am not entranced in Matt Damon’s looks I was able to let my mind wonder about how I could have improved his situation up there. Now, I am not advocating for putting a 30-year-old underachiever, like myself, on NASA’s team, but I bet I could have improved the astronaut’s life expectancy by replacing white potatoes with sweet potatoes. Here are 4 ways sweet potatoes could have saved Matt Damon’s life on Mars.
1. Eating sweet potatoes increases your energy levels
Space causes the human body to produce fewer red blood cells, which leads to fatigue, dizziness, and overall low energy levels. Iron in food helps the body produce blood cells at a higher rate and sweet potatoes contain more iron than white potatoes. Substituting sweet potatoes would have contributed to higher energy levels and brain function, allowing Mr. Damon to avoid blowing up his decompression chamber. If he had not blown up his decompression chamber, he still would have had his potato crop, reducing the need for rationing his food supply.
2. Eating sweet potatoes Helps promote healthy skin.
In the movie, NASA’s public relations director wanted him to take a selfie, while he was on Mars. Matt Damon ended up taking an unflattering picture of himself that was not shown to the public.
Sweet Potatoes contain around 1,000 times more Vitamin A than regular potatoes. Vitamin A promotes healthy eyes and skin. Even though Mars is closer to the sun, the atmosphere does not allow for sun bathing, decreasing Matt Damon’s intake of vitamin A. Without a consistent source of Vitamin A, Mr. Damon’s character would have dry, rough skin as well as corneal inflation making him look less attractive. Eating sweet potatoes would have supplied him with enough Vitamin A to easily be portrayed as “attractive”. If he had a more attractive appearance, NASA would have shown his selfie to the public, which would have garnered more sympathy for his cause.
Side Note: Luckily the director didn’t realize that Vitamin A is essential for the reproductive process too or there could have been Alien Matt Damon babies.
3. Sweet potatoes heal wounds.
To the amazement of my wife, Matt Damon took off his shirt to reveal some pretty nasty wounds and of course a six pack. Vitamin C is crucial for healing wounds. Sweet potatoes contain more Vitamin C. If his diet consisted of sweet potatoes rather than regular potatoes, his wounds would have healed faster.
4. Sweet Potatoes boast morale.
There is a scene in the movie where Matt Damon runs out of ketchup and turns to dipping his potatoes in Vicodin. While I have never tried Vicodin dipped sweet potatoes, I know they cannot be good for you. Luckily sweet potatoes simply taste better than regular potatoes and can be mixed with other condiments. The versatility of the sweet potato would be a huge morale boost to someone stuck on Mars.
Men may be from Mars and it may have some pretty awesome candy bars, but I believe growing sweet potatoes instead of white potatoes on the red planet would have been the best option for Matt Damon’s character. If anyone from NASA is reading this please note that sweet potatoes have more iron, 1,000 x more Vitamin A, more Vitamin C, and simply taste better than regular white potatoes. Sorry white potatoes, it’s science.
