low-cholesterol-diet-lower-high-blood-pressure

Please pardon the harsh language, but I need to say this plainly and strongly.

EVERYTHING YOU KNOW ABOUT CHOLESTEROL IS BULL$HIT

Here’s a little crash course on cholesterol and heart disease. We know that most of the time atherosclerosis and heart disease patients usually have elevated levels of cholesterol in their blood. We also know that many of these patients have deposits of the goopy fatty stuff crusting on the insides of their blood vessels. These things are correlated, which means they are usually found together. That part is true. The conclusion that was made was that the dietary fat and serum cholesterol levels of these patients was the direct cause of the hardening of the blood vessels, the clogs and the heart attacks. That part is suspect, and the topic of this article.

That is certainly a possibility, but there are other ways to perceive this correlation. One popular theory is that other forces acting on your blood vessels cause damage and thinning. Different theories attribute this damage to anything from pH levels, to a lack of vitamin-C in the diet, to any number of other dietary and lifestyle factors. When this damage occurs in the artery walls your body directs cholesterol to the site and clumps it up to harden and support and patch the thin or damaged areas. This is only supposed to be a temporary fix, and if the conditions that caused the damage continue then the “patches” will continue to accumulate until they form serious clogs and cause heart attack or a stroke, among other things.

Assuming that the presence of a large amount of cholesterol in the blood is a cause is kind of like assuming that because you always see firemen at burning buildings that they must have set the fires. That’s not to say that high cholesterol is something to ignore. It can be a warning sign of some condition that has caused the need for those artery “patches” I mentioned. Then again it also can mean nothing at all. Some people have what is known as “familial hypercholesterolemia.” That’s just a fancy way of saying that they are genetically programmed to have high levels of blood cholesterol. Many people with this genetic predisposition lead happy and healthy lives without ever developing heart disease.

But let’s take one more look at that original theory about the dietary fat and cholesterol clogging up the arteries and being the cause of the problem. Ask any plumber and they will tell you that this doesn’t make sense. We can all agree that in the body it’s the largest blood vessels that run directly in and out of the heart that get all this clogging and hardening action. In terms of clogged plumbing, the smaller blood vessels would be the biggest problems first. They would clog up badly and way before the larger arteries were even a noticeable problem yet. But that isn’t what the findings show. The findings suggest that the clogging is directed and targeted in those large blood vessels, and if that’s the case, then the body is doing it itself, as suggested above. That would make the clogging not a cause, but a symptom of a larger problem.

I don’t mean to leave this topic on a down note, but make sure that you are assessing other risk factors when evaluating high cholesterol. Watch out for other factors that can create a problem such as a family history of heart disease, poor diet, smoking, sedentary lifestyle, high stress, etc. Be smart and work with a physician before making any decisions.

For more information (and a LOT of it) you can read more at THINCS (The International Network of Cholesterol Skeptics). It’s members include scientists from all over the world, including several nobel laureates. Some of them may disagree on what does cause heart disease, but they all agree that cholesterol does not.

China Study: A Closer Look

Thursday, July 15th, 2010

the-china-study

When I first heard about THE CHINA STUDY, and then later thumbed through the copy my girlfriend brought home from the library, I was immediately both interested and skeptical. As a fitness professional I am always interested in new food research, but I am also immediately skeptical of any conclusions until I see the data for myself. When the book first landed in my lap I opened to a random spot somewhere in the middle and found examples of bad scientific method straight away without even trying.

What struck me about Campbell’s conclusions from those first few pages was that he was disregarding way too many variables in his quest to support his points. He would describe the specific population, and ailment in a given section of the study and lay out some interesting numbers and then proceed to make astounding  leaps of logic that left me shaking my head, and saying “tsk tsk tsk.”

I don’t have the time or inclination to write a point-by-point breakdown of all the flaws in The China Study, but thankfully  RAW FOOD SOS does just that for us. What I love about her arguments is she backs them up with the actual numbers that Campbell used, she just approaches them with a sharper intellect. And did I mention the author, Denise minger, is a raw-foodie herself?

And before anyone gets angry with me (or Ms. Minger for that matter) for attacking The China Study, understand that we both already eat a heavily plant-based diet ourselves. I myself avoid dairy almost entirely, and eat meat products only a few times a week. Before finding the omnivorous equilibrium I have now I spent five years as a vegetarian, and then another five years eating large amounts of animal products. I won’t speak further for the author, but I have discovered that with regard to eating, like with most things in life, the middle of the road is the best way to go.

I want to be clear that there are elements of the book I appreciated as well. He does lay out several things that most people don’t know and should. He also does draw some compelling conclusions here and there. But, in the name of good science, and good analysis, I cannot let the book stand as gospel as so many people do. It has issues, and most of those issues stem from a misleading representation of the statistics, and Ms. Minger’s website does a good job of illustrating these issues in a clear and concise manner.

Mark’s Daily Apple

I recently came across a website dedicated to “primal living” written by a man named Mark Sisson, and I’m hooked. It’s called MARK’S DAILY APPLE and I’ve added a permanent link to the right. It’s a great site, with day after day of new and interesting articles. Under his ABOUT ME section he discusses his personal health philosophies as the following:

“In a nutshell:
- fresh, organic, unprocessed food – no junk!
- daily activity – whether it’s the gym or a walk along the beach, it all counts
- plenty of quality sleep
- plenty of water, no soda or sweetened drinks
- antioxidants galore – the key to limiting stress
- a good fish-oil supplement

- lots of essential fats, reckless amounts of vegetables, and clean protein
- time for fun – don’t take anything too seriously – ethical behavior – because what goes around comes around
- taking responsibility for yourself and your life – openness to new things and ideas”

I’ve highlighted the two that I don’t really agree with. Those are both two things that you have likely heard from several different sources, but guess what: there is no real science to back that up. Those ideas have been disseminated by so many media outlets (magazines, infomercials, tv news, websites, etc) that we no longer question it, but where’s the evidence? I’ve never seen any. He has his own line of nutritional supplements which science has shown do next to nothing for you, so that tells you his incentive to advocate them.

But what I really like about this guy’s website is he is all about questioning everything. On that same “About Me” page he says just that. He gently jokes that you shouldn’t even always take his word for it. Ask questions, find out for yourself, and take your health into your own hands. YES! I love it!

Towards the end of a great article about a new SHAMPOO-LESS MOVEMENT he shares the following nugget of wisdom:  “Our bodies, left to their own devices, really can take care of themselves.” YES! You don’t need expensive supplements, or freaky-crazy detox diets. Just make good choices to give your body the tools it needs, and you’ll be fine.

He brings all kinds of interesting information to you, like THIS REVIEW OF A BOOK CALLED THE VEGETARIAN MYTH

Mediterranean Diet

t1largmediterreanandietgi1

I am not really an advocate of any dogmatic style of eating. I tend to look for what I know to be healthy and keep the nasty stuff (meaning sugary/oily snacks) down to a minimum. But The Mediterranean Diet does have a lot going for it. It’s high in fiber, vitamins and minerals and good fats, and low in animal products. Take a look at THIS ARTICLE ON CNN

If you’re looking for something new that is NOT a crash diet, but a whole new way of looking at eating, this might be for you.

Keep It Simple

chipsIf you’re becoming more conscious of what you put in your body, always remember that the simplest list of ingredients is always going to be better for you. A short list AND a list of words you recognize as actual food.

Here’s a great example. Lets look at a bag of Doritos:

Ingredients: Whole corn, corn oil, salt, cheddar cheese (cultured milk, salt, enzymes), buttermilk solids, whey protein concentrate, romano cheese from cow’s milk (cultured pasteurized milk, salt, enzymes), tomato powder, monosodium glutamate, onion powder, partially hydrogenated soybean and cottonseed oil, whey, wheat flour, garlic powder, artificial colors (including yellow 6 lake, yellow 5 lake, yellow 6, red 40, red 40 lake), dextrose, sugar, disodium phosphate, lactic acid, natural and artificial flavor, spice, citric acid, parmesan cheese (cultured milk, salt, enzymes), disodium inosinate and disodium guanylate.

I’ve highlighted in red the things that most people won’t recognize. Do you know what that stuff is? I do, and most of it is garbage that your body does not need.

And here’s a bag of Lay’s Potato Chips:

Potatoes, sunflower oil, salt

Obviously, chips aren’t the greatest thing to be eating anyway, but I am realistic. I know my clients like chips from time to time, and I like them too. Next time you want something crunchy though, reach for Lay’s, or better yet, baked crackers.

Trans Fats

Friday, June 19th, 2009

In the case of food “bad guys” we take a good idea too far in this country. We were terrified of fat when I was a kid, and then later, when I was in college, nobody was eating carbs. …sigh. I’ve already covered that, so let’s move on.

It’s amazing to me that after Denmark and Canada banned foods containing hydrogenated oils, and health researchers all over the world came to the same conclusion about them, that they have only kind of became a “bad guy” in America. People are talking about them, but nobody really seems to understand. We all cried wolf over fats and carbs, so now trans fats seem like just another silly thing to blow over. Trust me, people, this is NOT another silly fad. This one is a REAL bad guy.

Trans fats are the real monsters in our food, and many of us are shoveling them down our throats with reckless abandon. If you’re eating chips, or crackers, or cookies, or snack cakes, then chances are you are eating them. WIKIPEDIA had this to say about it:

“Unlike other dietary fats, trans fats are neither required nor beneficial for health. Eating trans fats increases the risk of coronary heart disease. For these reasons, health authorities worldwide recommend that consumption of trans fat be reduced to trace amounts. Trans fats from partially hydrogenated oils are generally considered to be more of a health risk than those occurring naturally.”

To close, I will just leave you with this description of precisely what hydrogenated means. Keep in mind, if you’re eating like most Americans, you put LOTS of this in your body every day.

“First they take vegetable oil, soy, corn or cottonseed, of a cheap quality. The oil may be already rancid from the extraction process. Then they mix it with tiny metal particles, usually nickel oxide, a toxic substance, and then they subject the mixture to hydrogen in a high pressure high temperature reactor. Next, in order to remove the unappetizing odor of the mixture and give it a better consistancy, soap-like emulsifiers and starch are squeezed in, and the oil is, yet again, subjected to high temperatures like steam cleaning. The resulting mixture is an unattractive grey color. In order to make the hydrogenated solid oil mixture look like butter, the original gray is removed by adding bleach and coal tar dyes. Finally, strong flavors are mixed in to make it taste like butter. And this mixture is compressed into tubs or blocks which the consumer buys as margarine.”

Mmm Mmm Gluten

Friday, June 19th, 2009

Some of you have been probably been hearing a new food buzz word the last couple years, and wondered what it was all about.

I am referring to the trend towards “gluten free” everything.

Gluten is a protein that occurs in grasses, and most notably in wheat. It comprises about 80% of the protein in wheat, to be precise. To about 99.9% of Americans this protein is not only harmless, but quite nutritious. In a very small minority it can create painful and dangerous side effects, but as I said that is only in a small percentage of us. It’s estimated to be less than 1% of us. To read more about the science of gluten and this reaction, CLICK HERE.
You may or may not have noticed it, because if you’re like most people, you many not really read the labels of what you eat very closely, but there has been a growing list of products that are bragging about being gluten free in recent years. I had a jar of natural peanut butter the other day that was gluten free. I had to laugh out loud because there was never any reason for a person to suspect a jar of peanut butter contained gluten in the first place.

But, that brings me to my point. Most of us wouldn’t worry if there was gluten in our peanut butter, and most of us don’t need to worry about gluten at all, and in fact eat it all the time. It’s in wheat bread, it makes bagels chewier, and gives pizza crust it’s texture. The only people who need to concern themselves with gluten should be well-informed by their doctor about what foods are dangerous for them, and what ingredients to look for, and they would know better than to suspect peanut butter. When the list of ingredients is “peanuts and salt” it’s pretty obvious that it’s safe for anyone who doesn’t have a peanut allergy.

The reason it’s on that label is because of this growing fear of gluten. It’s becoming the new “bad guy” in food. We’ve had many over the years, this one is only the newest. There was a while where fat was our enemy, and then it was sodium for a while, and who can forget the most idiotic one; the Atkins attack on carbs. There was a kernel of truth in those attacks of the past. Yes, in large amounts, those things are bad for you. BUT in the right amounts those things are good for you. Fat is necessary for healthy skin and hair and joint function, among other things. Too little sodium intake can make you just as sick as too much. And carbs… besides the fact that they are you body’s primary fuel source, they are your brain’s ONLY fuel source… do I even need to address this one again?

Anyway, that’s a whole different discussion. The point is, gluten is not your enemy… unless you have Celiac disease, then it is, but you probably already know that. If not, then you will know soon enough, but more than likely you are one of the overwhelming majority of us who simply don’t need to care.

Carbs Are Not Your Enemy

Friday, May 1st, 2009

carbs

I am never going to suggest anybody CUT carbs. Carbs are like gasoline for your internal motor, and more importantly they are the ONLY fuel your brain runs on. That’s right, your brain does not run on fat or protein or anything else. Only carbs.

But Many of us eat carbs in gigantic quantities, more than we really need. Cutting DOWN is always a good idea.
