oh my aching foot!

Well folks, I must say that I'm extra glad to be off work, and for it to be summer break, since my health problems seem to keep on coming. 

My right "pointer" toe has been giving me problems for a while.  I get shooting electrical pain running up from my toe to my ankle in a straight line.  I didn't do much about it, because of my interceding gall bladder trouble.  Once that was done, and I was more mobile again, the foot pain started back up.

Finally I went to my doctor, who gave me a (in my view) dreaded cortisone shot in between my pointer and middle toe (ouch!).  I was referred to podiatry.  Well, the cortisone did nothing but give me injection site pain, as is my usual experience with them.

I went in to the podiatrist, x-rays showed no stress fracture, and (yay) no arthritis in my foot at all.  He determined I had a Morton Neuroma.  What is that, you may ask?  Well......

Morton's Neuroma is an inflammation of and tissue buildup around the nerves between the metatarsal bones in the foot.  As the nerves grow, they push against each other and all of the other ligaments, tendons, bones, etc. in that area.  It causes heat to radiate from the area (it feels like your foot is too close to a fire, weird), you feel like theres a stone or marble in your foot, a lot of electrical-like nerve pain, etc.  It is no fun.
This neuroma is between the third and fourth toe, mine is between the second and third.


In most cases the neuroma is caused by wearing ill fitting shoes, shoes that are too tight, or pointy-toed shoes that compress the toe area together.  Or it can be caused from over flexation, as in tennis players, runners, or ballet dancers.  Clearly, I am none of those (although I did play tennis in high school). 

My neuroma condition is a culmination of the past 35 years.... well I guess it would actually be 34, since I wasn't walking at birth.  Because I was such a giant baby who was a month overdue, and because my mom is so little, I was cramped in the womb (but unwilling to leave apparently, as I was born a month late).  My hips turn in instead of being open flat (it's hard to explain).  Because of this my feet turn in.  When I was a baby my terrible pediatritian thought it was a problem with my feet, and I had to wear these stupid baby shoes (which were not as trendy as baby shoes today!) attached to braces while I slept to "retrain" my feet.  It wasn't until I was ready to enter kindergarten that we had better insurence and they figured out it was my hips.  By this time the only remedy would have been to break my hips, readjust them, put me in a full body cast for a while, and then reteach me how to walk.  Clearly this was not feasible.

As a result of my hip issue, I had to teach myself to walk with my feet straight.  This happened around middle school when this evil girl kept making fun of me, telling me "You walk like a retard, why aren't you in the retard class?"  Clearly I was her intellectual superior, as I was walking from Honors Literature to Advanced Band when she tormented me, but I digress.......

So, I figured out how to walk kind of normal, however, I still pronate to the outside of my feet.  My shoes wear very unevenly.  If I'm very tired, say, after walking around Disneyland for the whole day, my feet will still turn in.  And when I'm standing they are more than likely pointed inward and crossed over each other.  That's just my comfortable way of standing. 

After 30+ years all of this pronation causes my arches to collapse when I step, which causes the nerves and bones in the "ball" area of my foot to compress and irritate each other.  Now there's a little tumor like growth of nerve tissue that's built up and is causing trouble. 

What treatment is needed?  Well first they try the cortisone shots which (A) I don't believe in and (2) don't work on me, ever.  I have to go have my feet casted and have hard orthotic insoles made which I have to wear in all of my shoes.  If those don't make any difference they will have to look at surgery to remove the neuroma, leaving what is called a "nerve stump" which can start the process again, but, since I'd still be wearing the inserts, hopefully would not grow back. 

The surgery would be done from the top of my foot.  They would go in, carefully cut between all the ligaments and tendons and such to go down to the nerve.  They would cut out the swollen knob.  This could cause permanent numbness in one or both affected toes, which could cause balance issues.  And, as you all know, I don't need more balance issues, I have enough trouble just standing as it is.  But, it would be worth it to relieve all of this burning and shocking pain.  It even affects my sleep - I awaken suddenly in the night with horrible pain. 

In the photo (1) is a swollen digital nerve, (2) is the Morton's Neuroma to be removed, and (3) are the two individual nerves that rubbed together, became inflamed, and caused the neuroma to develop.

Following the surgery the site has to be kept dry until the follow up appointment - which should be interesting to achieve.  After 10 days or so the stiches are removed, and the foot can be washed (yay!).  The foot must be elevated for 10 to 14 days.  After that a "post operative shoe" must be worn.  The more you walk, the longer you have to wear it.  Finally, after 6-8 weeks regular shoes can be attempted, with the orthodic insoles still in them. 

So, that's the road ahead of me.  I'd like to be hopeful that the insoles will work, but since this has been 34 years in the making, I'm having a hard time being optomistic.  It seems like I have a long road ahead, and it's frustrating.  Not being able to walk far without pain, not sleeping well (which I already had issues with), having random sudden flashes of pain for no apparent reason, it's very annoying.  But, it's all in God's hands, and I feel blessed that I don't have to work while this is going on, and I have a full month before school starts.  I'm also lucky to have a temporary handicap placard so that when school does start I'll be able to park close to the buildings I need.

I will post updates as they occur.  And a piece of advice to all of you - wear shoes that fit well, massage your feel after wearing heels or tight shoes, and make sure you're walking flat on your feet.  =)

oil oil everywhere, but which is safe to eat? The truth about Canola

As someone who tries to eat healthfully (as we all should), one major question me and mine have run across is which cooking oil is best to use.  Olive oil has been used for thousands of years, but it is difficult to use for stir fries and the like because of its distinct taste and low smoke point. 

So, I've decided to research and find out which oils are best, and worst.  Upon beginning said research, I was overwhelmed with information on Canola.  I was already aware of some of the negatives in this widely used product, but I discovered some even more disturbing information.  So, this will be the first in a series on cooking oils and thier benefits and negatives.

First off - The Truth about Canola

All oils are made of pure fat, but not all fats are created equal.  In this day and age I'd hope that everyone knows that monounsatrated fats are the best for us, these are found in olive oil.  They are heart healthy, and do not contribute to high "bad" cholesterol.  Also well known is the fact that trans fats are bad.  They can be carcinogenic (cancer causing) and contribute to heart problems. 

There are a few ways to get oil from seeds, beans, olives, etc.  The cold press method is just that, a giant press that squeezes the oil from the product.  No heat is applied in this method, so none of the oil molecules are damaged or transformed.  Olive oil is usually cold pressed.  Items more difficult to press, are processed in giant cranks that chew up the product until the oil is released.  This is the expeller method, and it also requires no heat.  Finally there are refined oils.  Items like soybeans and rapeseeds (which become canola oil) are so difficult to extract oil from must be chemically changed.  High heat is involved, and then various chemical solvents are added to remove the oil from the seed.  The oil becomes instantly rancid because of the exposure to high heat, so deodorizers are added to mask the smell.  The oils are also bleached and have anti-foaming agents added in.  By the end of the process, these oils are pale, clear, have no smell or flavor, and have no health benefits, but may actually be dangerous.  Because they are so processed, they have  very high smoke point, and are therefore popular in the resturant and fast food industries for frying.

But now onto Canola. 

First off, there is no Canola plant.  Canola oil is derived fom a genetically manipulated rapeseed.  The rapeseed is actually a toxic member of the mustard family.  Mustard gas, used during WWI was made from the rapeseed plant.  In order to make this toxic plant edible it must be genetically modified.  The levels of Erucic acid must be reduced.  One way to accomplish this is through irradiation, another is to genetically implant another plant's genes into the rapeseed plant.  Either way, the Canola plant does not exist in nature. 
In addition to genetic modification, saturated fats must be added to the rapeseed oil.  The end result is 60% monounsaturated fat and 10% Omega 3 fatty acids, which on the surface seems good.  

Throughout North America in the 1970's, polyunsaturated fats were being promoted, dispite the fact that more and more scientific evidence was pointed towards the fats being linked with increasing Cancer rates.  Ideally, the push should have been toward known healthy monounsaturated fats, like those in olive oil, however, supplies were limited, and it would have been very costly for wide manufacturing into salad dressings and (ew) margarine.

Instead of pushing healthy oils or focusing on a way to lessen use of herbicides and lowering fuel costs, research was done to transform the toxic rapeseed into a marketable oil.  Because of it's toxic nature, insects naturally avoid the rapeseed plant.  Farmers found this wonderful.  Baldu Stefanson of the University of Manitoba is given credit as the first to successfully engineer the plant that would become Canola Oil. 

The oil resulting from the modified rapeseed plant was originally called LEAR (Low Erucic Acid Rapeseed).  Marketing a product containing the words Rape and LEAR proved difficult, and the name was changed to Canola (CANadian Oil, Low Acid), the term was coined in 1978.  Today Canola is Canada's largest export.

Canola was further genetically modified to increase the content of the monounsaturated Oleic acid, which is naturally and abundantly found in olive oil. 

In 1995 the infamous Monsanto (don't know about Monsanto?  Watch "Food Inc." and you'll never look at corn or soy the same way again..... seriously, watch it!) got involved and created a strain of rapeseed/canola that is resistant to RoundUp (also created by Monsanto).  Today over 82% of canola crops are genetically modified by Monsanto.
In April of 1997 Monsanto was forced to recall over 60,000 bags of genetically modified canola seeds.  an unapproved gene had slipped into the seeds by mistake, one that was not approved for human consumption.  I find it terrifying that these extra genes are just lying around, and are able to be engineered into foodstuffs.  The seeds in the recall were enough to plant over 700,000 acres of crops. 

Canada began marketing Canola to the U.S. in the 1980's.  In order to be sold in stores, Canola had to be granted GRAS (generally regarded as safe) status from the FDA.  Food and herb products labeled GRAS are generally products that have been used for hundreds of years with no adverse side effects reported.  Canola, however, was a brand new product, that did not exist naturally, and that was made from a plant known to be toxic.  How was Canola granted GRAS status so quickly?  No one knows for sure, but it is widely rumored that the Canadian government spent $50 million US on its Canola campaign.  Once in the US market, Canola spread to world wide use by the 1990's.

Canada's publicity campaign did not target the general public, but selectively advertised to the science and health care industries.  Due to it's high monounsaturated fat and omega 3 content, nutritionists began suggesting it to their patients.  Books like The Omega Plan and the Zone Diet pushed the use of Canola.  Even Andrew Weil was tricked by the canola propaganda for a while. 

In my mind, besides the problems I have with ALL genetically modified foods, there are 3 major problems with canola oil.  These are the traditional uses for rapeseed oil, the changes that take place in the oil during the refining process, and the negative effects that have appeared in experiments with canola oil. 

Rapeseed oil was originally used as a lubricant in the shipping industry.  Rapeseed/canola oils are also (still) used as lubricants, fuels, soap, synthetic rubber bases, and the slick finish on magazine pages.  Maybe it's just me, but it seems creepy to eat something that is was originally used to lubricate ship parts.

The oil refining process described here is not exclusive to canola oil.  It is used for many, including safflower and soy.  These are generally sold as "vegetable oil."  Most oil is refined with strong acids, and with the same base used in products to unclog drains.  The oil is heated to a very high temperature, which cause the Omega 3 fatty acids present to be either destroyed or mutated into trans fats.  The oil then enters a bleaching process which, according to Udo Erasmus, "removes every essential nutriant except fatty acids."  Because the oil has been turned rancid by the heat applied earlier, it undergoes a deodorization process to mask the rancid smell.  This is done through steam distillation, and the heat applied here transforms even more fatty acids into trans-fatty acids, which interfere with any beneficial ingrediants that might still be around.  Lastly, when the finished oil is used for cooking, either at home or in a resturant setting, even more trans fats may be created if the oil is heated to its smoking point.

The crux of this matter is that canola oil is advertised as the "best oil" to use because of its high percentage of monounsaturated fats and omega 3's.  In fact, the vast majority of these ingredients are destroyed during the refining process, AND, many of those once healthy ingredients are transformed into cancer causing agents.

Canola has only existed for 30 years, nothing is yet known about the long term effects this man-made product has on us, as humans.  No human trials were conducted before canola oil was released for sale.  The animal trials I will discuss were conducted after the oil's release, and are still being done (my personal views against animal testing notwithstanding, some pretty terrible things have happened in the name of canola oil). 

Soon after the creation of canola, an study showed that rats developed more heart leisons when being fed canola and flaxseed oils than on olive and sunflower oils.  Once the rats were no longer forced to eat the canola the leisons went away, but severe scarring remained.

In 1997 a study involving piglets (poor baby pigs - I detest animal testing!) resulted in the piglets developing severe Vitamin E defeciencies when fed mild with canola in it, dispite the fact that the piglets were given an adequate amount of Vitamin E. 
The study continued into 1998 as the same piglets suffered decreased platlet counts and increased platlet size.  When cut (again, animal testing is BAD), the piglets bled longer than they should have.

As for humans, Canola consumption has been linked to Vitamin E defeciency and growth retardation.  For this reason the FDA has banned canola us in infant formula.  Canola can also cause a latex-like consubstance that have caused red blood corpuscles to clump together.  Canola can also deteriorate mylein sheaths (the coating around nerve cells) possibly leading to nervous disorders such as Altzheimer's Disease and Multiple Sclorosis. 

So, overall, Canola would seem to be a bad thing.  I stopped using Canola a while ago, and I didn't even know a lot of these things. 

Stay tuned for the next installment of oil oil everywhere, but which is safe to eat?  I'm thinking it will be grapeseed oil.

As always, thanks for stopping by.  If you have questions about the history or healthfullness of any food,just let me know and I'll try to look into it.  <3
