At Austin Skye Wellness, we believe
that one's nutritional status has a major impact on health and
wellness, perhaps more so than any other single factor except maybe
lifestyle. Everyday, we participate in three activities that allow
chemicals to come into our bodies: that would be in the air we
breathe, the water we drink, and the food we eat. We put trust in
our elected officials and utility companies to see that our air and
water are as pure and safe as possible, and we would not allow them
to knowingly pollute our air or water or to allow them to become
unsafe. As a society, however, we have not given the same level of
concern to our food, as we have turned over the responsibility of
preparing our food to someone else, and in so doing we have given
up control over what goes into our food. We have become farther and
farther removed from the process of food preparation, and we have
allowed chemicals, preservatives, dyes, coloring agents, and flavor
enhancers to be added to food, when we would never consider adding
them ourselves. We have also given up control over the fat and
sugar content of our food, resulting in the epidemic of obesity we
now face. Other conditions seem to be on the rise as well, such as
asthma which is felt to be possibly related to food allergens; a
number of cancers, possibly linked to chemicals in our food;
degenerative diseases such as osteoarthritis, which is associated
with diets high in animal protein; and cardiovascular disease and
stroke, our nation's #1 cause of death which is associated directly
with the amount of dietary fat we consume.
The good news is that we can reclaim
control of the preparation of our food, and make informed decisions
regarding its' content. We can eliminate those things from our food
that are just not needed when we prepare our food ourselves, and
which have absolutely no beneficial effect on our health and are
likely harmful. We have solid scientific proof regarding the
effects our dietary choices can have on our health, allowing us to
make choices that can improve our overall health and well being, or
to choose a dietary plan aimed at treating a specific medical
problem.
The following nutritional advice can
be followed safely by anyone, except for those with specific
metabolic deficiencies. And following this advice will result in
improved health as outlined below. If we are seeing you for a
specific problem, we might be emphasizing specific parts of this
advice that might be especially helpful for you. Or, we may modify
this advice or add to it, depending on the problem.
EAT A PLANT-BASED, PREDOMINANTLY
VEGETARIAN DIET
Would it help you to believe in a
predominantly vegetarian diet if we told you it was endorsed by the
following agencies: The National Institutes of Health (NIH), the
National Academy of Science, the National Cancer Institute (NCI),
the U. S. Department of Agriculture, The National Research Council,
The U.S. Department of Health and Human Services, the American
Heart Association, and the American Cancer Society. No? Well, what
if we told you that the dietary guidelines that follow could either
lower your risk of developing or lessen the difficulty you are
having with the following problems:
Cardiovascular Disease.
Stroke.
Many types of
Cancer.
Inflammatory conditions such as
Rheumatoid Arthritis.
Autoimmune conditions such as Lupus
and Multiple Sclerosis.
Allergic conditions such as Asthma,
Eczema, and Atopic
Dermatitis.
Degenerative conditions such as
Rheumatoid
Arthritis.
Some behavioral and emotional
problems such as depression, PMS, and
ADHD.
Now that you are convinced that such
dietary choices would benefit you, how is this
accomplished?
THE FOOD GUIDE
PYRAMID:
In 1992, the USDA introduced the Food Guide Pyramid as a way of
selecting our foods such that we achieve a nearly vegetarian diet.
A copy of the pyramid is attached, with explanations regarding
servings and
calories.
The emphasis in the pyramid is on
increasing our consumption of fruits, vegetables, and grains, and
minimizing our consumption of fats and sweets. Accomplishing this
requires that we assume control of purchasing our food fresh, from
a supermarket, and that we follow through with the preparation of
that fresh food. This allows little room for prepared or processed
food due to the higher fat and sugar content of such
foods.
The health benefits of the
Pyramid are accomplished in the following
ways:
An increase in dietary fiber- This
results in a lowering of serum cholesterol and triglyceride,
improved bowel function and a lower risk of colon cancer.
A decrease in the consumption of
saturated fat and an increase in the consumption of essential fatty
acids- This results in a reduced risk of cardiovascular disease and
stroke. Saturated fat is found primarily in animal sources, the
consumption of which is limited in the pyramid, and is substituted
with unsaturated fat and essential fatty acids found in seeds,
legumes (nuts and soy), and grains.
An increase in the consumption of
antioxidants and phytochemicals such as flavonoids and carotenoids-
This results in a reduced risk of several cancers, a reduced risk
of cardiovascular disease and stroke, and possibly a slowing down
of the aging process.
Flavonoids can be found in the red and purple pigmented fruits and
vegetables such as: Tomatoes, red cabbage, red onions, berries, and
plums.
Carotenoids can be found in the yellow and orange fruits and
vegetables such as: carrots, apricots, yams, mangoes, and squash,
as well as in green leafy vegetables and in legumes, seeds and
grains. You will see recommendations regarding supplementation with
beta-carotene, but evidence shows that naturally acquired carotenes
are more effective than those taken as a supplement.
A decrease in the consumption of
animal protein- Diets high in animal protein have been linked to
inflammatory conditions such as rheumatoid arthritis, autoimmune
conditions such as lupus and MS, and degenerative conditions such
as osteoarthritis.
A reduced intake in the consumption
of refined sugar- these are the so-called "simple sugars."
Consumption of simple sugars is associated with high insulin
levels, which are linked to higher rates of cardiovascular disease
and stroke, and which may effect certain mood and behavioral
disorders.
These five areas are addressed separately
below.
AN INCREASE IN DIETARY
FIBER
Fiber refers to the indigestible and
non-absorbable components of our food. It consists primarily of the
walls of the cells of our fruits and vegetables, composed primarily
of cellulose. The consumption of high amounts of fiber is
associated with a lowering of serum cholesterol, and is believed to
lower the risk of colon cancer and possibly breast cancer. It also
improves bowel function and lessens the development of the
diverticular diseases in the colon, diverticulitis and
diverticulosis.
Fiber also contributes to satiety,
which is the sensation of fullness. As such, it can contribute in
this way to calorie restriction and weight
management.
The ability of dietary fiber to
lower cholesterol has been strongly proven in multiple studies of
oat bran and oatmeal. This effect seems to be stronger in people
with high serum cholesterol compared to people with normal
cholesterol who show little change in cholesterol from dietary
fiber. Consumption of the equivalent of 3 gm of soluble oat fiber
will lower total cholesterol by 8-23%. The importance of this is
that each 1% drop in total cholesterol result in a 2% decrease in
the risk of developing heart disease. 3 gm of fiber is provided by
approximately one bowl of oat bran cereal or oat
meal.
The target for dietary fiber
consumption is 35gm of fiber per day. Examples of fiber content are
as
follows:
1 medium apple- 3.5
gm
1 medium banana-2.4
gm
1 medium orange- 2.6
gm
1 medium tomato- 1.5
gm
½ cup celery- 1.1
gm
1 cup broccoli- 4.4
gm
1 cup carrots- 4.6
gm
½ cup baked beans- 8.8
gm
½ cup navy beans 6
gm
½ cup white rice- 0.2
gm
½ cup brown rice-1.0
gm
½ cup all bran- 8.5
gm
½ cup grape nuts- 2.8
gm
1 ¼ cup corn flakes 0.6
gm
DIETARY FAT
In a perfect vegetarian world, we would consume no animal fat at
all. The American Heart Association and the American Cancer Society
have established guidelines that recommend limiting the intake of
fat such that the calories from fat make-up no more than 30% of
total calories. As well, by limiting the intake of animal fat in
favor of fat from seeds, legumes, nuts, and seeds, the type of fat
consumed changes from saturated fat to polyunsaturated fat, which
lowers the risk of heart disease and stroke. The amount of fat
consumed from animal protein should be limited to 4-6 ounces per
day, and should consist primarily of fish, skinless poultry, or
lean lean lean cuts of
beef.
SATURATED FAT VS. UNSATURATED
FAT:
The gist of saturated vs. unsaturated fat is as follows. The term
saturation refers to the number of hydrogen atoms attached to the
carbon atoms in the fat molecule. That is, a saturated fat has the
most hydrogen atoms possible attached to the carbon atoms, but
that's not important. What is important is that this chemical
property determines which fats will cause deposits in the arterial
walls of the heart, or will lead to inflammatory reactions in our
joints, or will affect the deterioration and function of our cells
and lead to cancer. Saturated fat is obtained primarily from animal
sources, and is solid at room temperature. Unsaturated fat is
obtained primarily from vegetable sources, and is liquid at room
temperature. Saturated fat causes heart disease, stroke, cancers,
inflammatory conditions, skin conditions, and a variety of other
disorders. Unsaturated fat is associated with a lower risk of these
conditions, and can even cause improvements in the symptoms
associated with
them.
So, how does this effect the choices
I make in my selection of food?
Where can my fat come
from?
THE WORST
CHOICES:
High intake of saturated fat from
animal sources such as
beef.
High intake of saturated fat from
butter.
The use of oils such as corn oil,
safflower oil, and soy. Eventhough these are composed of
polyunsaturated fats, they are unstable when exposed to heat and
light and form toxic derivatives called lipid
peroxides.
The use of Margarine and Shortenings
due to their content of "Trans" fatty acids (see separate
description
below).
High intake of
cholesterol.
THE BEST
CHOICES:
Follow the Food Guide Pyramid. See
Pyramid
Guidelines.
Vegetables: 3-5 servings per
day.
Fruits: 2-4 servings per
day.
Breads, Grains, Cereals, Pastas, and
Rice: 6-11 servings per
day.
Milk, Yogurt, and Cheeses: 2-3
servings per
day.
Meat, Poultry, Fish, Eggs, Beans,
and Nuts: 2-3 servings per
day:
Limit animal protein (and its fat
content) to 4-6 ounces per day, coming mostly from lean beef, fish,
and skinless
poultry.
Oils: Choose Olive Oil and Canola
Oil.
Avoid Margarine: See section on
"Trans"
Fat.
Use Butter instead of Margarine, but
in limited amounts ("Sparingly" according to the
pyramid.)
Limit calories from fat to 30% of
total calories, with only 10% of that coming from saturated
fat.
Calories from fat should preferably
come from fruits, veggies, nuts, and beans rather than from animal
sources. This favors polyunsaturated and monounsaturated fat over
saturated
fat.
Limit cholesterol intake to 300 mg
per day. Only foods of animal origin contain
cholesterol.
"TRANS" FAT:
The FDA recently changed the labeling requirements for food, now
requiring that labels contain not only the amount of fat contained
in food, but also the amount of what is called "trans" fat, short
for trans-fatty acids. This change is prompted by the recognition
that trans fat poses some health
risks.
Understanding trans fat requires a
brief chemistry lesson. Certain chemicals, such as fats, can occur
in two similar but geometrically different forms called isomers.
Isomers are basically the same chemical, but appear "backward" as
if you held them in front of a mirror. These two backward shapes
are the isomers, and are given the names "cis' and
"trans."
We have told you that the preferred
fats are the unsaturated fats, and the fats to be avoided are the
saturated fats ("sat fat"), and that sat fat is generally solid at
room temperature and unsaturated fat is generally liquid at room
temperature. The problem occurs in the preparation of margarine and
shortening, where normally liquid unsaturated oils, in the "cis"
configuration, are partially hydrogenated to make them solid,,
whereby they become more saturated and are now in the "trans"
configuration.
Having said that, why are "trans"
fat-containing margarines and shortenings a
problem?
The problem is that even though
margarine contains mainly unsaturated fat, it has been changed to
the trans configuration, which behaves as if it were saturated,
raising the risk of heart disease, etc. Trans fat raises LDL
(so-called "bad" cholesterol) and lowers HDL ("good" cholesterol).
Trans fat also interferes with the metabolism of essential fatty
acids (see that section) which serve many functions, such as the
formation of healthy cell membranes and the production of
prostaglandins. Alterations in essential fatty acid metabolism have
been linked to an increased risk of certain cancers including
breast
cancer.
It is for this reason that the
labeling change to include trans fat was made and why our advice at
Nature's Healthcare is to avoid trans fat, so much so that we now
believe it is wiser and healthier to use butter sparingly than
margarine liberally, and shortening
never.
ANTIOXIDANTS
Normal cellular metabolism produces
substances called "Free Radicals." If left unchecked, free radicals
are capable of producing cellular damage, and they are felt to be
involved in the development of certain cancers, of cardiovascular
disease, and in the cellular destruction that accompanies aging.
The compounds that keep free radicals in check are called
"Antioxidants." Consumption of antioxidants has been shown to
reduce the risk of cardiovascular disease and cancer, and may slow
the aging process.
The major antioxidants
are:
Vitamin
C.
Vitamin
E.
Carotenoids, mainly
beta-carotene.
Selenium.
Flavonoids.
Antioxidant supplementation is more
effective when taken as a group rather than selecting a specific
antioxidant to be taken alone and the best way to obtain
antioxidants is felt to be from a combination of supplementation
along with a diet high in antioxidant-containing
foods.
