There's no
shortage of health myths out there, but I believe the truth is
slowly but surely starting to seep out there and get a larger
audience. For example, two recent articles actually hit the nail
right on the head in terms of good nutrition advice.
Shape
Magazine features a slide show on "9 ingredients nutritionists
won’t touch,"1
and authoritynutrition.com listed “11 of the biggest lies
of mainstream nutrition."2
These health
topics are all essential to get "right" if you want to protect
your health, and the health of your loved ones, which is why I
was delighted to see both of these sources disseminating spot-on
advice. I highly recommend reading through both of them.
Here, I
will review my own top 10 lies and misconceptions of mainstream
nutrition some of which are included in the two featured
sources, plus a few additional ones I believe are important.
Lie # 1:
'Saturated Fat Causes Heart Disease'
As recently
as 2002, the "expert" Food & Nutrition Board issued the following
misguided statement, which epitomizes this myth:
"Saturated
fats and dietary cholesterol have no known beneficial role in
preventing chronic disease and are not required at any level in
the diet."
Similarly,
the National Academies’ Institute of Medicine recommends
adults to get 45–65 percent of their calories from carbohydrates,
20-35 percent from fat, and 10-35 percent from protein. This is
an inverse ideal fat to carb ratio that is virtually guaranteed
to lead you astray, and result in a heightened risk of chronic
disease.
Most people
benefit from 50-70 percent healthful fats in their diet for optimal
health, whereas you need very few, if any, carbohydrates to maintain
good health... Although that may seem like a lot, fat is much
denser and consumes a much smaller portion of your meal plate.
This dangerous
recommendation, which arose from an unproven hypothesis
from the mid-1950s, has been harming your health and that of your
loved ones for about 40 years now.
The truth
is, saturated fats from animal and vegetable sources provide the
building blocks for cell membranes and a variety of hormones and
hormone-like substances, without which your body cannot function
optimally. They also act as carriers for important fat-soluble
vitamins A, D, E and K. Dietary fats are also needed for the conversion
of carotene to vitamin A, for mineral absorption, and for a host
of other biological processes.
In fact,
saturated is the preferred fuel for your heart! For more information
about saturated fats and the essential role they play in maintaining
your health, please read my previous article The
Truth About Saturated Fat.
Lie # 2:
'Eating Fat Makes You Gain Weight'
The low-fat
myth may have done more harm to the health of millions than any
other dietary recommendation as the resulting low-fat craze led
to increased consumption of trans-fats, which we now know increases
your risk of obesity, diabetes and heart disease the very
health problems wrongfully attributed to saturated fats...
To end the
confusion, it's very important to realize that eating fat
will not make you fat!
The primary
cause of excess weight and all the chronic diseases associated
with it, is actually the consumption of too much sugar especially
fructose, but also all sorts of grains, which rapidly convert
to sugar in your body. If only the low-fat craze had been a low-sugar
craze... then we wouldn't have nearly as much chronic disease
as we have today. For an explanation of why and how a low-fat
diet can create the very health problems it's claimed to prevent,
please see this previous
article.
Lie # 3:
'Artificial Sweeteners are Safe Sugar-Replacements for Diabetics,
and Help Promote Weight Loss'
Most people
use artificial sweeteners to lose weight and/or because they’re
diabetic and need to avoid sugar. The amazing irony is that nearly
all the studies that have carefully analyzed their effectiveness
show that those who use artificial sweeteners actually gain
more weight than those who consume caloric sweeteners. Studies
have also revealed that artificial
sweeteners can be worse than sugar for diabetics.
In 2005,
data gathered from the 25-year-long San Antonio Heart Study showed
that drinking dietsoft drinks increased the likelihood
of serious weight gain, far more so than regular soda.3
On average, each diet soft drink the participants consumed per
day increased their risk of becoming overweight by 65 percent
within the next seven to eight years, and made them 41 percent
more likely to become obese. There are several potential causes
for this, including:
- Sweet
taste alone appears to increase hunger, regardless of caloric
content.
- Artificial
sweeteners appear to simply perpetuate a craving for sweets,
and overall sugar consumption is therefore not reduced leading
to further problems controlling your weight.4
- Artificial
sweeteners may disrupt your body's natural ability to "count
calories," as evidenced in studies such as this 2004 study at
Purdue University,5
which found that rats fed artificially sweetened liquids ate
more high-calorie food than rats fed high-caloric sweetened
liquids.
There is
also a large number of health dangers associated with artificial
sweeteners and aspartame in particular. I've compiled an ever-growing
list of studies pertaining to health problems associated with
aspartame, which you can find here.
If you're still on the fence, I highly recommend reviewing these
studies for yourself so that you can make an educated decision.
For more information on aspartame, the worst artificial sweetener,
please see my aspartame
video.
Lie # 4:
'Your Body Cannot Tell the Difference Between Sugar and Fructose'
Of the many
health-harming ingredients listed in the featured article by Shape
Magazine all of which you're bound to get in excess
if you consume processed foods fructose is perhaps the greatest
threat to your health. Mounting evidence testifies to the fact
that excess fructose, primarily in the form of high fructose corn
syrup (HFCS), is a primary factor causing not just obesity, but
also chronic and lethal disease. In fact, I am convinced that
fructose is one of the leading causes of a great deal of needless
suffering from poor health and premature
death.
Many conventional
health "experts," contend that sugar and fructose in moderation
is perfectly okay and part of a normal "healthy" diet, and the
corn industry vehemently denies any evidence showing that fructose
is metabolically more harmful than regular sugar (sucrose). This
widespread denial and sweeping the evidence under the carpet poses
a massive threat to your health, unless you do your own research.
As a standard
recommendation, I advise keeping your total fructose consumption
below 25 grams per day. For most people it would also be wise
to limit your fructose from fruit to 15 grams or less. Unfortunately,
while this is theoretically possible, precious few people are
actually doing that.
Cutting out
a few desserts will not make a big difference if you're still
eating a "standard American diet" in fact, I've previously
written about how various foods and beverages contain far more
sugar
than a glazed doughnut. Because of the prevalence of HFCS in foods
and beverages, the average person now consumes 1/3 of a pound
of sugar EVERY DAY, which is five ounces or 150 grams, half of
which is fructose.
That's 300
percent more than the amount that will trigger biochemical havoc.
Remember that is the AVERAGE; many actually consume more than
twice that amount. For more details about the health dangers of
fructose and my recommendations, please see my recent article
Confirmed Fructose
Can Increase Your Hunger and Lead to Overeating.
Lie # 5:
'Soy is a Health Food'
The meteoric
rise of soy as a "health food" is a perfect example of how a brilliant
marketing strategy can fool millions. But make no mistake about
it, unfermented soy products are NOT healthful additions to your
diet, and can be equally troublesome for men and women of all
ages. If you find this recommendation startling then I would encourage
you to review some of the many articles listed on my Soy
Index Page.
Contrary
to popular belief, thousands of studies have actually linked unfermented
soy to malnutrition, digestive distress, immune-system breakdown,
thyroid dysfunction, cognitive decline, reproductive disorders
and infertility even cancer and heart disease.
Not only
that, but more than 90 percent of American soy crops are genetically
modified, which carries its own set of health risks.6
I am not opposed to all soy, however. Organic
and, most importantly, properly fermented soy does have
great health benefits. Examples of such healthful fermented soy
products include tempeh, miso and natto. Here is a small sampling
of the detrimental health effects linked to unfermented
soy consumption:
|
Breast cancer |
Brain damage |
Infant abnormalities |
|
Thyroid disorders |
Kidney stones |
Immune system impairment |
|
Severe, potentially fatal food allergies |
Impaired fertility |
Danger during pregnancy and breastfeeding |
Lie # 6:
'Eggs are a Source of Unhealthy Cholesterol'
Eggs are
probably one of the most demonized foods in the United States,
mainly because of the misguided idea implied by the lipid hypothesis
that eating egg yolk increases the cholesterol levels in your
body. You can forget about such concerns, because contrary to
popular belief, eggs are one of the healthiest
foods you can eat and they do not have a detrimental
impact on cholesterol levels. Numerous nutritional studies have
dispelled the myth that you should avoid eating eggs, so this
recommendation is really hanging on by a very bare thread...
One such
study7,
conducted by the Yale Prevention Research Center and published
in 2010, showed that egg consumption did not have a negative effect
on endothelial function – a measure of cardiac risk –
and did not cause a spike on cholesterol levels. The
participants of the Yale study ate two eggs per day for a period
of six weeks. There are many benefits associated with eggs, including:
|
One egg contains 6 grams of high quality protein and all 9
essential amino acids |
Eggs are good for your eyes because they contain lutein and
zeaxanthin, antioxidants found in your lens and retina. These
two compounds help protect your eyes from damage caused by
free radicals and avoid eye diseases like macular degeneration
and cataracts |
Eggs are a good source of choline (one egg contains about
300 micrograms), a member of the vitamin B family essential
for the normal function of human cells and helps regulate
the nervous and cardiovascular systems. Choline is especially
beneficial for pregnant mothers as it is influences normal
brain development of the unborn child |
|
Eggs are one of the few foods that contain naturally occurring
vitamin D (24.5 grams) |
Eggs may help promote healthy hair and nails due to their
high sulphur content |
Eggs also contain biotin, calcium, copper, folate, iodine,
iron, manganese, magnesium, niacin, potassium, selenium, sodium,
thiamine, vitamin A, vitamin B2, vitamin B12, vitamin E and
zinc |
Choose free-range
organic eggs, and avoid “omega-3 eggs” as this
is not the proper way to optimize your omega-3 levels. To produce
these omega-3 eggs, the hens are usually fed poor-quality sources
of omega-3 fats that are already oxidized. Omega-3 eggs are more
perishable than non-omega-3 eggs.
Lie # 7:
'Whole Grains are Good for Everyone'
The use of
whole-grains is an easy subject to get confused on especially
for those who have a passion for nutrition, as for the longest
time we were told the fiber in whole grains is highly beneficial.
Unfortunately ALL grains, including whole-grain and organic varieties,
can elevate your insulin levels, which can increase your risk
of disease. They also contain gluten, which many are sensitive
to, if not outright allergic. It has been my experience that more
than 85 percent of Americans have trouble controlling their insulin
levels especially those who have the following conditions:
- Overweight
- Diabetes
- High blood
pressure
- High cholesterol
- Protein
metabolic types
In addition,
sub-clinical gluten intolerance is far more common than you might
think, which can also wreak havoc with your health. As a general
rule, I strongly recommend eliminating or at least restricting
grains as well as sugars/fructose from your diet, especially if
you have any of the above conditions that are related to insulin
resistance. The higher your insulin levels and the more prominent
your signs of insulin overload are, the more ambitious your grain
elimination needs to be.
If you are
one of the fortunate ones without insulin resistance and of normal
body weight, then grains are fine, especially whole grains as
long as you don’t have any issues with gluten and select
organic and unrefined forms. It is wise to continue to monitor
your grain consumption and your health as life is dynamic and
constantly changing. What might be fine when you are 25 or 30
could become a major problem at 40 when your growth hormone and
level of exercise is different.
Lie # 8:
'Milk Does Your Body Good'
Unfortunately,
the myth that conventional pasteurized milk has health benefits
is a persistent one, even though it’s far from true. Conventional
health agencies also refuse to address the real dangers of the
growth hormones and antibiotics found in conventional
milk. I do not recommend drinking pasteurized milk of any
kind, including organic, because once milk has been pasteurized
its physical structure is changed in a way that can actually cause
allergies and immune problems.
Important
enzymes like lactase are destroyed during the pasteurization process,
which causes many people to not be able to digest milk. Additionally,
vitamins (such as A, C, B6 and B12) are diminished and fragile
milk proteins are radically transformed from health nurturing
to unnatural amino acid configurations that can actually worsen
your health. The eradication of beneficial bacteria through the
pasteurization process also ends up promoting pathogens rather
than protecting you from them.
The healthy
alternative to pasteurized milk is raw
milk, which is an outstanding source of nutrients including
beneficial bacteria such as lactobacillus acidophilus, vitamins
and enzymes, and it is, in my estimation, one of the finest sources
of calcium available. For more details please watch the interview
I did with Mark
McAfee, who is the owner of Organic Pastures, the largest
organic dairy in the US.
However,
again, if you have insulin issues and are struggling with weight
issues, high blood pressure, diabetes, cancer or high cholesterol
it would be best to restrict your dairy to organic butter as the
carbohydrate content, lactose, could be contribute to insulin
and leptin resistance. Fermented organic raw dairy would eliminate
the lactose issue and would be better tolerated. But if you are
sensitive to dairy it might be best to avoid these too.
Lie # 9:
'Genetically Engineered Foods are Safe and Comparable to Conventional
Foods'
Make no
mistake about it; genetically engineered (GE) foods may be one
of the absolute most dangerous aspects of our food supply today.
I strongly recommend avoiding ALL GE foods. Since over 90 percent
of all corn grown in the US is GE corn, and over 95 percent all
soy is GE soy, this means that virtually every processed food
you encounter at your local supermarket that does not bear the
"USDA Organic" label likely contains one or more GE components.
To avoid GE foods, first memorize the following list of well-known
and oft-used GE crops:
Fresh zucchini,
crookneck squash and Hawaiian papaya are also commonly GE. It’s
important to realize that unless you're buying all organic food,
or grow your own veggies and raise your own livestock, or at
the very least buy all whole foods (even if conventionally
grown) and cook everything from scratch, chances are you're consuming
GE foods every single day... What ultimate impact these foods
will have on your health is still unknown, but increased
disease, infertility and birth defects appear to be on the
top of the list of most likely side effects. The first-ever
lifetime feeding study also showed a dramatic increase in
organ damage, cancer, and reduced lifespan.
Lie # 10:
'Lunch Meats Make for a Healthy Nutritious Meal'
Lastly,
processed meats, which includes everything from hot dogs, deli
meats, bacon, and pepperoni are rarely thought of as strict no-no’s,
but they really should be, if you’re concerned about your
health. Virtually all processed meat products contain dangerous
compounds that put them squarely on the list of foods to avoid
or eliminate entirely. These compounds include:
- Heterocyclic
amines (HCAs): a potent carcinogen, which is created when
meat or fish is cooked at high temperatures.
- Sodium
nitrite: a commonly used preservative and antimicrobial agent
that also adds color and flavor to processed and cured meats.
- Polycyclic
Aromatic Hydrocarbons (PAHs): Many processed meats are smoked
as part of the curing process, which causes PAHs to form.
- Advanced
Glycation End Products (AGEs): When food is cooked at high temperatures including
when it is pasteurized or sterilized it increases the
formation of AGEs in your food. AGEs build up in your body over
time leading to oxidative stress, inflammation and an increased
risk of heart disease, diabetes and kidney disease.
This recommendation
is backed up by a report commissioned by The World Cancer Research
Fund8
(WCRF). The review, which evaluated the findings of more than
7,000 clinical studies, was funded by money raised from the general
public, so the findings were not influenced by vested interests.
It's also the biggest review of the evidence ever undertaken,
and it confirms previous findings: Processed meats increase your
risk of cancer, especially bowel cancer, and NO amount of processed
meat is "safe." A previous analysis by the WCRF found that eating
just one sausage
a day raises your risk of developing bowel cancer by 20 percent,
and other studies have found that processed meats increase your
risk of:
- Colon
cancer by 50 percent
- Bladder
cancer by 59 percent
- Stomach
cancer by 38 percent
- Pancreatic
cancer by 67 percent
Processed
meats may also increase your risk of diabetes by 50 percent, and
lower your lung function and increase your risk of chronic obstructive
pulmonary disease (COPD). If you absolutely want or need a hot
dog or other processed meats once in awhile, you can reduce your
risk by:
- Looking
for "uncured" varieties that contain NO nitrates
- Choosing
varieties that say 100% beef, 100% chicken, etc. This is the
only way to know that the meat is from a single species and
does not include byproducts (like chicken skin or chicken fat
or other parts)
- Avoiding
any meat that contains MSG, high-fructose corn syrup, preservatives,
artificial flavor or artificial color
Ideally,
purchase sausages and other processed meats from a small, local
farmer who can tell you exactly what's in their products. These
are just some of the health myths and misconceptions out there.
There are certainly many more. The ones listed above are some
of the most important ones, in my view, simply because they’re
so widely misunderstood. They’re also critical to get "right"
if you want to protect your health, and the health of your loved
ones. For more great advise, please review the two featured sources.
