The Lipid-Hypothesis vs. Science

I'm no scientist, but I remember learning early on in scienve class that the hyposthesis is the basis, the foundation, if you will, of good, sound science. Without the hypothesis all is conjecture.  Now, I unfortunately do not own a Webster's, but my American Heritage College Dictionary defines hypothesis as
1) A tentative explaination that accounts for a set of facts and can be tested by further investigation; a theory. 2) Something taken to be true for the purpose of argument or investigation; an assumption. emphasis mine.  In other words one guesses at the reason for something he does not understand.  He then investigates to find out whether or not he was correct, and shares what he has learned and why he was right or wrong. Sadly this does not appear to be the case with the lipid-hypothesis, rather they seem to have made an assumption and then set about proving it correct at all cost.
Lest my ranting fall on uninformed ears, the lipid -hypothesis was coined by Ancel Keys in 1950 as scientists and doctors stuggled to gain insight into the alarming increases in deaths from heart disease since the 1920s.  In essence it states that saturated fats and cholesterol which in turn leads to heart disease. Two main studies are sited in support of this theory: the Framingham Study and David Kritchevsky's rabbits.  The results are somewhat startling when you consider the effect they have had on the treatment and prevention of heart disease since.
Kritchevsky conducted and experiment in which he fed large ammounts of cholesterol to rabbits.  While he did, indeed find that his rabbits developed atherosclerosis, his findings do little to prove the lipid-hypothesis if viewed objectively.  For one thing, rabbits are vegitarian animals.  They were never meant to consume animal foods as humans, omnivores, were. Second, these rabbits were fed highly processed cholesterol that is not found in any natural foods and third, the  kind of plaque which developed in the rabbits is compeletly different from what develops in humans.  Nonetheless, the AHA ran with it, presenting the hypothesis as proven fact and recommending the Prudent Diet in which the beef, eggs, lard and butter that americans were used to consuming were replaced by liquid vegetable oils, margerine, chicken and cold breakfast cereals.
The Framingham Study launched in 1948 with follow up studies in 1964 and 1978.  In the earliest portion of the study nearly 1000 people were asked about their eating habits and test for blood cholesterol levels.  The findings? There was no connection between diet and cholesterol levels.  This portion of the study was never published!  The follow-up in 1964 revealed that almost half of those who had suffered heart attacks actually had low cholesterol; in 1978 it was determined that "For every 1mg/dl drop [in blood cholesterol] there was an 11 percent increase in coronary and total mortality".  Reardless, the "Circulation" journal published this statement from the AHA: "The reasults of the Framingham Study indicate that a 1 percent reduction...of cholesterol [corresponds to] a 2 percent reduction in CHD risk."  The exact opposite of what was actually found.  There are numerous studies that prove saturated fat plays an important roll in all of our bodily functions, and liquid vegetable oils are actually liked to heart disease.  More on that another time.

Where are we now? Our journey.

We started on this journey in early 2005 when we were transferred to Knoxville, TN with my husband's new job.  Driving through the Blue Ridge Mountains to our new home, my husband suddenly looked at me and said "we should find someone who sells raw milk".  As a young boy, he drank raw milk as it was gifted his father,the pastor of a small church in New York, from a dairyman in the congregation.  I readily agreed having drunk (and loved) the raw milk we were given for breakfast, on a mission trip to East Germany. Little did we know at the time where this would lead us. We were propelled onward by unseen forces.  Always meeting the right people and the right time.  I had no access to the Internet at the time, but read everything I could find and asked tons of questions of the family we found to buy our "pet grade" milk from.   I began making butter, homemade yogurt, and even experimented with sauerkraut and kombucha.  We were really on a roll, but it all came to a screeching halt when we moved again and couldn't find a good source of raw milk close to us, nor could we afford the organic meats and produce at the only, tiny, health food store in near proximity.  Since mail order is something my husband was unwilling to consider at the time, and I still did not have access to the wealth of information on the Internet, all seemed lost

Why Get Physicallly Fit?

Let's face it, we all want to look our best.  I'm no exception. I'm not going to lie to you, I've never really considered myself fat. I've never had a six pack, and my thighs have never exactly measured up to my standards but I have a small frame-- 4' 11" tall and not a whole lot on it.  This morning I weighed 105.5 on my scale that measures by the half pound.  I'm not too concerned with that number, It's about 3 pounds more than I weighed when I got married 8+ years ago; but since that time not only have I gained 3 pounds, I've also given birth to 4 good sized healthy babies.  That has taken a toll on my body, plain and simple.  Over the years I figure (if you include what the babies and amniotic fluid weighed) I've gained and lost over 200 pounds!  I've exercised pretty much whenever I wasn't pregnant, mostly "the Firm" workouts.  But I never really got where I wanted to be.  I never lost this pouch on my belly that hangs over my belt and makes me feel gross.  I never really understood why I was lifting the weight that I was lifting, the number of reps, or exactly which muscle group I was supposed to be working, and how that would benefit me.

About this blog

This is my first blog post. Ever. Honestly, I never thought I would have a blog; I've always kinda thought "who really cares what you think", but the blogging world is opening up to me.  There are so many great blogs out there.  They aren't just dumb online journals that anyone can read.   At this point im my life, I am starting (over) on a journey that I wanted to chronicle; and since I am terrible at keeping a journal, and I am hopeful that my experiences could possibly benefit others, the idea of a blog now appeals to me.
