Sorry so late getting this in, but I was preoccupied with studying for my FAA test for my private pilot license. It paid off though. I got a great score!
Here is the recap from last Saturday's show:
Reading the “Nutrition Facts” panels on foods may not be as
reliable an indicator of a food’s nutrients as you may think.
"Good Morning America"
hired a lab to test a dozen packaged food products to see if the nutrients
matched the labels.
The government allows foods to contain 20 percent more diet-damaging
ingredients than the label lists before taking enforcement action, and all 12
products were indeed over in one way or another. Three were actually over by
more than 20 percent, including:
-David's Sunflower Seeds with 23 percent more saturated fat
-Ritz Crackers with 36 percent more sodium
-Wonderbread with 70 percent more total fat
Meanwhile, manufacturers are allowed to list "0"
on the label even if their product contains up to half a gram of the item in
question. Despite a "0" on the labels, there were small amounts of
saturated fat in Baked Lay's Potato Chips, Rold Gold pretzels, Special K Cereal
and Grape Nuts Trail Mix Crunch, and trans fats in Nabisco Cheese Nips.

How Does Aspartame Damage Your Brain?
|
|
Consuming a lot of aspartame may inhibit the ability of
enzymes in your brain to function normally, according to a new review by
scientists from the University of Pretoria and the University of Limpopo.
The review found that high doses of the sweetener may lead to
neurodegeneration. It has also previously been found that aspartame
consumption can cause neurological and behavioral disturbances in sensitive
individuals.
Specifically, the review found a number of direct and indirect changes that
occur in your brain as a result of high consumption levels of aspartame,
including disturbing:
- The metabolism of
amino acids
- Protein structure and
metabolism
- The integrity of
nucleic acids
- Neuronal function
- Endocrine balances
Further, the breakdown of aspartame causes nerves to fire
excessively, which can indirectly lead to a high rate of neuron depolarization.
Despite these growing concerns, neither the European Food Safety Authority
(EFSA) or the U.S. Food and Drug Administration (FDA) have changed their
guidelines regarding the safety of the ingredient or intake advice.

Natural Trans Fats Actually Have Health Benefits
|
|
Artificial trans fats are bad for you, but naturally
occurring ones may have very different effects.
A diet with enriched levels of trans vaccenic acid (VA) -- a natural animal
fat found in dairy and beef products -- can actually reduce risk factors
associated with heart disease, diabetes and obesity, according to a
researcher from the University
of Alberta.
The benefit was due in part to the ability of VA to reduce the production of
chylomicrons, which are particles of fat and cholesterol that form in your
small intestine following a meal. They are then rapidly processed
throughout the body, and may be related to a variety of conditions
arising from metabolic disorders.
Experiments on rats showed that VA in the diet could lower total cholesterol
by approximately 30 percent, LDL cholesterol by 25 percent, and triglyceride
levels by more than 50 percent.

Pet peeve of the day: Fitness and nutrition “experts” who
are overweight! When listening to an “expert” on weight loss or any personal
trainer on fitness, first ask yourself, “does it seem to be working for them”?
This can easily be assessed with a quick glance at their belly or hips! Also,
why do the “well known” trainers look so good on their product ads, but when
you see them in every day life, they don’t look so good? Could it be photo
retouching? Inconsistent lifestyle? Getting in shape for the photo shoot? Things
that make you go hmmmmm……
Next, is my pet peeve of the week and a response to recent
media attention about proper hydration. I was so peeved in fact, I wrote a
whole article on it for my X Gym members (and radio show listeners). Please
read it below.
Do You Really
Need To Drink 8 Glasses of Water a Day?
By PJ Glassey, CSCS
No! That’s
not enough! I’m really irritated with a few quacks (“Dorkters” I like to call
them) blithering on recently about how we don’t really need to drink 8 glasses
of water per day. They are just trying to get press time and create a stir by
going against current wisdom and sound, healthy advice. They are also merely
following the Dorkter who initially came out with this story a few months ago
to get himself in the press to promote his new book.
Following the lead guy is a common
technique Dorkters use, because they don’t have to do any research or work of
their own. They just rewrite the original story in their own words and then
claim it as their idea. I have seen several Dorkters saying the exact same
thing since this story initially came out a few months ago, so it’s obvious
they are just riding on his coattails.
The interesting fact to me, is that
these Dorkters don’t cite any reasons that drinking 8 glasses of water is bad!
They make the false claim that there aren’t enough well designed research
studies proving 8 glasses or more is necessary, but totally neglect to cite a
single study that supports drinking less than 8 glasses a day. It took me all
of about 10 minutes to find the 12 research studies listed at the bottom of
this article to support my opinion. Anyone can Google Pub Med online and see
for them self how many well designed studies are out there now.
Shouldn’t doctors be spending their
time telling us about stuff that would harm us or help us, instead of wasting
their time talking about stuff that doesn’t matter if it isn’t true? This just
proves my point that they are pointlessly blithering because they know it will
get them some attention. There are no health problems associated with drinking
8 glasses per day, but many serious health problems have been proven to result
from drinking less than 8 glasses a day, including death! Shouldn’t the
Dorkters err on the safe side if they are doing us a service and not try to
convert people to hypo hydration and all of its proven risks?
So far every “expert” I have seen
who has claimed that we don’t need 8 or more glasses of water per day has a
little fat to lose themselves, and every layperson who has repeated this
message to me has also been at least moderately overweight. If I am only
hearing this message from those with excess weight, it sure seems to confirm
the fat loss benefits of proper hydration.
I did run across one water-naysayer
who appeared to be relatively thin (at least between the ears), but I could
detect a little “pooch” in his stomach area despite his loose shirt. He stated
he was proof that my claim in the preceding paragraph was false, so I just
responded, “OK, I’ll count to three, and then we will both pull up our shirts
and do a quick comparison of my 12-20 cups a day abs to your 5-7 cups a day
abs.” I started counting, and by the time I got to 2, he had already turned
around and stormed off.
Our brains are 85% water, so it
figures that only the dehydrated people are preaching the less water message in
spite of all the scientific evidence available. Even if there were no
scientific proof for proper hydration, it would still make for basic common
sense. I guess us smart, hydrated folks have to “dumb it down” for the
dehydrated population. If you are one of the 75% of Americans who are chronically
dehydrated, I’ll try to type slowly for the rest of this article so you can
keep up.
With the lack of water intake,
abundance of coffee, sodas, and alcohol, it’s no wonder everyone is always sick
and overweight! The bottom line is that even if you doubt what I am saying
here, the risk of getting too little water is much worse than the risk of
getting a little too much. If I’m wrong, you are only making more trips the
bathroom. If I’m right, your whole life changes, and I’ve seen that happen over
and over! Let’s just look at a few of the most common general knowledge side
effects of both sides of the coin:

The
low-water “Dorkters” also waste their time talking about the dangers of drastic
over hydration. Drinking too much water to the point of upsetting your
electrolyte balance (hyponatremia) is very hard to do. This would require
drinking at least your weight in ounces over a 12 hour period, so hyponatremia
really isn’t an issue for people without Obsessive Compulsive Disorder. Some
extreme endurance athletes and babies of stupid parents can fall victim to
hyponatremia, but it takes such high water volumes to cause problems
(especially in our high sodium culture), it’s hardly worth mentioning.
If you want to know how much water
your body uses in a day, just weigh yourself right before bed, and then again
right when you wake up. You will be 1-2 pounds lighter in the morning, simply
from exhaling water vapor while you slept! This means that if you stayed asleep
for 24 hours, you would breathe out 48-96 ounces of water in that time. This
equates to 6-12 glasses of water right there! Now add normal daily activities with some conversation, and you are
already over the traditional 8 glass recommendation even before exercise!
Our thirst mechanisms do not work
right when we are chronically dehydrated. Our bodies are forced to pull water
out of our food to keep us alive, and this teaches our system to tell us we are
hungry when we are really just
thirsty! I’ll restate this
point for those of you who are dehydrated and may be falling behind by now: You
have taught your body that it must get its water from food, so it craves food
instead of water when it needs water!
If you don’t believe this, try
drinking your proper amount of water for 3 weeks, and you will see for yourself
that you get thirsty more often than you get hungry instead of vice versa. This
is because when you are properly hydrated, and your body is getting its needs
from water instead of extracting it from food, it just asks for more water!
Many people have lost fat from proper hydration alone, because their food
consumption goes down so much after their thirst mechanism gets dialed in
properly.
Fat loss from proper hydration is
also tied into your liver function. When you are dehydrated, your kidneys need
help and your liver comes to their rescue. One of the liver’s main jobs is to
extract fat out of your tissues to be burned off, and when the liver is busy
helping the kidneys, guess which job it’s not doing anymore?
Water also keeps your immune system
functioning optimally. When we are ill, we lose water at an accelerated rate
because we are blowing our nose, sweating, coughing, expectorating, and in the
worst cases, launching out one end and/or the other. Lots of fluid is being lost and it must be
replenished quickly, because our cells are 70-90% water and this is where the
war is waging between the good guys and the virus or bacteria!
Your blood plasma is mostly water.
Plasma acts as a reservoir that can either replenish insufficient water or
absorb excess water from tissues. When body tissues need additional liquid,
water from plasma is the first resource to meet that need. Plasma circulation
plays a vital role in regulating body temperature by carrying heat generated in
core body tissues through areas that lose heat more readily, such as the arms,
legs, and head. It’s pretty easy to see the damage done when you are dehydrated
while you are sick with a fever.
Your skin is your first defense
against infection. When you are dehydrated, your skin cracks and your lips
chap. This provides nice little gateways for tiny little viruses and bacteria
to sneak through. Mucus membranes are
also one of your first lines of defense. When those are dried up from a lack of
water, bad stuff gets by them too. White blood cells are the internal defense
mechanisms that take care of the stuff that gets into your bloodstream. Guess
what their main ingredient is? Yep, water. They can’t fight for you effectively
if you are not hydrating them too!
Another reason we preach water so
hard at the X Gym is because muscles are 75% water. When you train with us, you
are breaking down your muscles, much like a tornado would break down your house
(appropriate analogy don’t you think?). If you give your body a little excess
water, you are providing excess building
materials to rebuild. This is like Home Depot dropping off too much lumber to
rebuild your house after the storm. You get to add on and make it better than
before!
Most gyms make you buy your water
so they can make more money off of you. If they do have free water, it comes
out of a drinking fountain straight from municipal sources with all the toxic
city chemicals included for your convenience. You probably don’t want to drink
out of the fountain anyway because you just saw Bruno Barbell Head wrap his
lips around the nozzle and then spit some back out to clear out the extra
saliva production from the steroids he’s on.
Instead of charging you for water, we pay for
the best possible filtration process and give it to you free. Our WETCOOLERS.COM systems filter the water
through three different stages, ending with reverse osmosis filtration, for the
purest water available. Then it goes to a stainless steel holding tank, where
it is sterilized by activated oxygen so you get pure, sterile, filtered water
in your cup.
We have the best water system
because we have the best workouts, and for you to get the best results, you
need the best water absorption. We encourage members to bring extra water
bottles so they can take this water home too, so fill up! It’s another benefit
of being an X Gym member!
The only way you can depend on your
thirst mechanism to accurately tell you when you need water (and not more food)
is to be properly hydrated. To calculate your water needs, divide your body
weight in half and then drink that many ounces of water each day. Some people
under 100 pounds might need more, and others over 250 pounds might need less,
but it’s a good general rule.
Another important point the
Dorkters fail to mention is that heavy people, well-muscled individuals, and
genetically heavy sweaters will suffer much worse effects from less than 8
glasses a day than those of “normal weight” and sweat rates. Under-hydrated
individuals with weight problems will crave food to satisfy their broken thirst
mechanism even more than normal weight people, which further perpetuates their
weight problem.
Children are at greater risk for
dehydration than adults due to their higher surface-to-mass ratio.
Additionally, children have different thirst sensitivities and body cooling
mechanisms than adults. Children differ from adults in total body water
content, and boys and girls differ in body water content with maturation.
Research in young adults shows that mild dehydration corresponding to only 1%
to 2% of body weight loss can lead to significant impairment in cognitive
function. Dehydration in infants is associated with confusion, irritability,
and lethargy; in children, it even produces decrements in cognitive
performance.
The research makes the case for
proper hydration indisputable, and simple common sense verifies it. Water is
free, so I’m not getting anything out of being on this soap box other than the
satisfaction of seeing you succeed in your fitness and health goals. Just do it!
