What we eat has an enormous affect on our overall
health. Thousands of studies support the idea that diet is highly
correlated with the risk of developing various chronic degenerative
diseases. Food is our greatest drug. It can either be used incorrectly
and cause great problems or when used correctly, will protect our
health.
Recent studies have shown that by eating a healthy diet and exercising
moderately we can significantly reduce the risk of developing diabetes,
heart disease, cancer, and host of other chronic degenerative diseases.
When you add cellular nutrition to this healthy diet and modest exercise
program, you give yourself the absolute best chance of protecting your
health or regaining your health if you have already lost it. The diet I
recommend will take into consideration all of these diseases. If you
already are suffering from one of these chronic degenerative diseases,
it will offer you the best of hope of regaining your health.
Carbohydrates
Carbohydrates are simply long chains of sugars that
are released at various rates in our bodies. These include foods like
fruits, vegetables, grains, and sugars. It has been assumed for the past
one hundred years that the more simple the sugar, i.e. table sugar,
candy, or soda pop one consumes, the faster the sugar is absorbed into
the blood stream and the quicker one’s blood sugar rises. This has given
rise to the concept of simple sugars versus complex sugars (having long
chains of sugars). Medical research has since shown us that this theory
was totally wrong. In the past 20 years, medical evidence and research
now suggest that the most important consideration is the glycemic index.
Few of us realize that processed carbohydrates like white bread, white
flour, rice, cereals, and natural white potatoes release their sugars
faster than table sugar. These foods are considered high-glycemic
carbohydrates, because the body is able to absorb these sugars very
quickly and cause our blood sugars to rise very rapidly.
On the other hand, carbohydrates such as: cauliflower, beans, asparagus,
apples, oranges, and grapes release their sugars more slowly, thus
keeping blood sugars from spiking. These are considered low-glycemic
carbohydrates. These carbohydrates also contain high amounts of
fiber—the indigestible portion of our food.
Fiber
Fiber passes through the gastrointestinal tract without being absorbed,
allowing not only our nutrients to be absorbed at a much slower pace,
but also helping to eliminate toxins as it cleanses the colon. An
increased amount of fiber is very important in our overall diet and can
be found in fruits, vegetables and whole grains.
I recommend between 35 and 50 grams of fiber each day. Most Americans
only consume 8 to 10 grams of fiber each day. Our paradigm is limited.
Perhaps a broader worldview would prove enlightening.
Dr. Burkitt, a surgeon, famous for the disease, "Burkitt’s Lymphoma,"
practiced in Africa for over 20 years. While in Africa, he did not see a
single case of colon cancer, diverticulitis, hemorrhoids, gall bladder
disease, or even appendicitis among the native population. He attributed
this remarkable finding to the fact that his native African patients
consumed 60 to 70 grams of fiber per day and typically had three to five
bowel movements every day. When Dr. Burkitt returned to the United
States, he spent most of his time promoting the health benefits of a
high fiber diet.
Constipation is a $3 billion business in the United States alone.
Patients in the U. S. think they are heroes when they have a bowel
movement every other day. When I refer a patient to the
gastoenterologist, I can count on the fact that he or she will recommend
my patient to eat more fiber. The fiber in low-glycemic carbohydrates
provides most of this necessary fiber, however, many of us need to
supplement our diet with additional fiber in order to obtain the 35 to
50 grams needed each day. I guarantee the tremendous health benefits
reaped by making this intentional effort will prove worthwhile.
Sugars
Glucose (the basic sugar that is used by the body
and that all carbohydrates eventually become in the body) is extremely
easy for the body to absorb and in turn raises blood sugar rapidly. The
rate at which the blood sugar increases (the glycemic index) of glucose
is rated at 100. Fructose (which is found in our fruits), on the other
hand, is more difficult for the body to absorb and is therefore
considered low-glycemic with an index of 19. White table sugar has a
glycemic index of 60 because it is a disaccharide (made up of two
molecules: on molecule of glucose and one molecule of fructose).
Therefore, it's glycemic index is between glucose and fructose.
Surprising to many, wheat and white bread actually have a very high
glycemic index of 70 and 77, which is even higher than table sugar. The
fine particle size and the exploded structure caused by processing of
the grain and the leavening action of the yeast makes the surface of
wheat starch extremely accessible to digestive enzymes. Because it
causes our blood sugar to rise very rapidly, white bread and wheat flour
bread are actually worse for our bodies than table sugar. Rice cakes,
one of our favorite diet foods, has one of the highest glycemic indexes
of any food--GI of 120.
The average dietitian does not utilize the glycemic index, which was
introduced in the early 80’s by Dr. Jenkins. However, a recent study in
the Journal of American Medical Association points out the potential
serious outcomes of America’s and the industrialized nation’s tremendous
use of high-glycemic foods. Problems like hypertension, obesity,
elevated cholesterol and triglycerides, heart attacks, strokes, and
diabetes are primarily related to our diet.
Dr. Walter Willet, head of nutrition and preventive medicine at Harvard,
in his book, Eat, Drink, and be Healthy (Simon and Schuster, 2001)
believes white bread, white flours, pasta, rice, and potatoes should be
placed at the top of the food pyramid above the sweets and snacks. In
turn, as you will learn in the Healthy for Life Program, I encourage my
patients and participants to eat less refined bread and switch
completely to whole grain breads, cereals, pasta, rice, and lower
glycemic red or new potatoes. By simply eating more whole foods—fruits
and vegetables, you are not only going to get the good fiber but also
these foods are primarily low-glycemic. Please read the discussion on
glycemic index to better understand this concept and learn why glycemic
load is also important.
Low-glycemic carbohydrates need to be balanced with good proteins and
fats. When protein and fat are combined with low-glycemic carbohydrates
during a meal, the absorption of sugar is slowed and the release of
glucagon (this hormone is the opposite of insulin) is stimulated. All of
the bad metabolic changes that occur with elevated blood levels of
insulin (high blood pressure, elevated triglycerides, lower HDL
cholesterol, central obesity) are actually reversed by increasing the
levels of glucagon. Click here to learn more about the glycemic index.
Protein
Protein has been maligned over the years due to the
tremendous focus on low-fat diets. Since most of the "bad" fats are
contained in proteins, we have thrown the protein out with the fat.
People have been led to believe that a high-carbohydrate, low-fat diet
is the healthiest diet we can eat. However, amino acids only found in
proteins are essential for all of our body’s functions, especially our
immune system. However, we must choose good protein sources.
Vegetable proteins are the very best proteins we can eat; the greatest
advantage of plant protein being the fact that it contains less
environmental toxins and chemicals than animal protein. Because of the
highly commercialized production of animal protein, it now contains
significantly greater amounts of hormones, antibiotics, and toxins.
Our bodies require 10 essential amino acids and vegetable protein is
sometimes criticized for not being complete. I don’t find any problem
with this because you can easily mix and combine many different plant
proteins. Some examples are soy protein, nuts, legumes, and certain
whole grains.
Cold-water fish offers the next best source of protein. Cold-water fish,
like salmon, mackerel, sardines, and tuna not only gives you a good
source of protein but also the good omega-3 essential fatty acids, which
I will discuss more under fats. Again, be aware of toxins these fish may
contain because of industrial pollution of our waters. Mercury poisoning
as well as many other toxins are increasing in all fish species.
Shellfish and larger saltwater fish are the worst. Knowing the source of
the fish is helpful.
Fowl is the next best source of protein. The fat of the bird is located
just underneath the skin and is not marbled into the meat. When you
remove the skin and fat from chicken and turkey, you have a very lean
piece of protein even though it contains saturated fat. Since most
toxins found in these animals accumulate in the fat, you can easily also
avoid them by removing the skin and fat from the meat leaving an
excellent source of protein. Organically grown fowl is a great choice if
you have it available.
Animal products are less desirable sources of protein due to the high
levels of saturated fat marbled inside red meat. I encourage my patients
to keep their consumption of red meat to a minimum, knowing that some of
us simply like to have a good steak once in a while. I recommend for
those patients who eat red meat to choose the leanest cut they can get.
Remember, no one needs to eat the 24-ounce cut. Eat small, fine cuts of
steak along with tasty low-glycemic vegetables. You do need to avoid
meats like bacon, hot dogs, salami, and lunchmeats. Organ meats (liver,
brain, and kidney) should also be avoided due to high toxin
concentrations.
Dairy products are the least desirable protein source because they have
the highest concentration of saturated fats. Milk, cheese, butter, and
buttermilk are ranked among some of the unhealthiest foods that we eat.
The problem is that they make our recipes taste so good. You can
markedly improve your diet by eating low-fat or non-fat milk and cheese.
Even though eggs contain a lot of cholesterol, cholesterol intake does
not appear to increase your cholesterol levels. Only saturated fat has
truly been found to increase your cholesterol levels. If you do eat
eggs, consider eating more egg whites than egg yolks. Even better is to
eat range fed chicken eggs, which also contains those good omega-3-fatty
acids.
Fats
Proteins have been given a bad rap, but not nearly as much as fats. The
consumption of fats in our diet has certainly been the talk of this past
half-century. Still, people are as confused about fats today as they
were a generation ago. In fact, in many ways they are even more
confused. The bottom line is that our bodies need fat to thrive and live
healthy. Fat is needed for many aspects of the cell but especially in
the formation of the cell membrane. Fat is also needed for the
production of many of our hormones, natural anti-inflammatories, and
basic energy needs. Not only must we decipher between good and bad fats,
but we need to know how and when to consume what kind of fats for good
health.
Saturated Fats
Saturated fats come primarily from animal fat and dairy products. These
are the worst fats that we can consume. These saturated fats increase
total cholesterol and LDL or "bad" cholesterol and lower HDL or "good"
cholesterol. Most Americans and people in the industrialized nations
consume the majority of their fats in the form of saturated fats.
Numerous studies reveal as I have mentioned earlier that the actual
consumption of cholesterol does little to increase our cholesterol
levels; however, the consumption of saturated fats and high-glycemic
carbohydrates play a large part in elevating cholesterol and
triglyceride levels. Most nutritionists now realize that it is not
simply the fat in our diet causing problems; but rather, the types of
fats we are consuming.
Polyunsaturated Fats
In the 1950’s, polyunsaturated fats became popular as a "healthy"
substitute for saturated fats. Fore example, vegetable oils were made
into margarine as a substitute for butter. Vegetable oils primarily
contain what is known as polyunsaturated fats. These fats do in fact
lower LDL or "bad" cholesterol, but the problem is that they also lower
HDL or "good" cholesterol. Polyunsaturated fats are also vulnerable to
oxidation and easily transform into "trans-fatty acids", which are
rancid fats. These fats make poor building blocks for our cell membranes
and are anything but healthy. Many vegetable oils are now subjected to a
process called partial hydrogenation. The reason food manufactures go to
the trouble of this process is to improve taste, spreadability,
pleasurable sensation in the mouth, and to extend shelf life. It has
nothing to do with making a "healthy" alternative.
To hydrogenate oils, manufactures heat the oils to high temperatures
under pressure with hydrogen gas. This process is stopped before it is
completed or all the fats would become saturated. However, this
abbreviated process provides a mixture of fats--saturated,
polyunsaturated, with a high concentration of trans-fatty acids. When
you look at food labels you will be amazed how many processed foods are
made of partially hydrogenated fat. The medical evidence is growing that
these partially hydrogenated fats or what is becoming known as rancid
fats are now considered the worst fats you can eat. I recommend avoiding
these kinds of fats all together. Therefore, anything that contains
partially hydrogenated fats in their label just leave on the grocery
shelf. In fact, these fats have been totally outlawed in Europe.
Monosaturated Fats
These fats are found in many of our vegetables, nuts, and certain
vegetable oils. These are considered healthy fats because they actually
help lower total cholesterol and LDL cholesterol while maintaining HDL
cholesterol levels. They are found in foods like cashews, almonds,
avocados, olive oil, and pistachio nuts. Virgin olive oil is a very good
source of these types of fats. Canola and peanut oils are also high in
these types of fat. Even though these fats do not contain the essential
fatty acids, they appear to be much healthier and in some ways
protective against heart disease. You must however be careful not to
heat these oils very much because they can become rancid fats very
easily. If you do use them in your cooking, you need to use very low
heat and use a high quality virgin olive oil.
Essential Fats: Omega-3 and Omega-6 Essential Fatty Acids
These essential fats are just that—essential. Our body cannot make them,
so we need to get them from our diet. They are critical in the
production of hormones called prostaglandins, which control
inflammation, cell growth and differentiation, blood clotting, and our
key nutrients for our immune system. We get plenty of omega-6 fatty
acids in the Western diet, however; almost all of us are deficient in
the omega-3 fatty acids.
Omega-6 fatty acids produce hormones (prostaglandins) that promote
inflammation, cell growth, and blood clotting. Omega-3 fatty acids
produce hormones (prostaglandins) with just the opposite affect. In the
event that you are injured, you need to have a good inflammatory
response to bring about quicker healing--the inflammatory response
brings blood and immune cells to the wounded area. However, if you have
not been hurt, an inflammatory response can damage tissue and cause
major problems, i.e. asthma, arthritis, and heart disease. Therefore, it
is critical that these essential fats are consumed in a balanced fashion
so that the hormones they produce will also occur in balance. If these
prostaglandins are not kept in balance they can cause serious health
problems such as cancer, heart disease, inflammatory diseases, and
autoimmune diseases.
Omega-6 fatty acids are found in meats, margarines, peanuts, poultry,
and many of our processed foods. Omega-3 fatty acids are found in
cold-water fish, flaxseed, soybeans, organic eggs, walnuts, and oils
made from flaxseed, walnuts, and soybeans. It is most beneficial to
consume these essential fats in a ratio of 2 omega-6 fatty acids to 1
omega-3 fatty acid (2:1 ratio). However, Americans consume an estimated
ratio of 20:1 and in some cases, 40:1 omega-6 fatty acids to omega-3
fatty acids. Is it any wonder that we have such tremendous inflammation
in our bodies, which is one of the major reasons we are in a health
crisis.
It is imperative that you make a concerted effort to consume foods high
in omega-3 fatty acids in order to balance out these two essential fats.
Eating adequate quantities of the omega-3 fatty acids will actually
lower your total cholesterol and LDL cholesterol. Most people simply
need to supplement their diet with cold-pressed flax seed, sunflower,
pumpkin seed oils or fish oil.
I realize most people will eat saturated fats and at times even
partially hydrogenated fats. Still, it is important to get the majority
of your fats from essential fatty acids and monosaturated fats. Many
researchers now argue that fat is not the problem, rather the types of
fats we are consuming is the major contributor to elevated cholesterol
levels.
Combining Carbohydrates, Proteins, and Fats
It is critical that you have a portion of carbohydrate, protein, and fat
with each meal or snack. Every time we eat, we need to be sure that we
are taking in good nutrition and that we are not going to be spiking our
blood sugar. We need to eat for hormonal control and not calorie
control. Insulin is our "storage" hormone and most of us do not want to
store any more fat than we already have.
Glucagon, on the other hand, actually utilizes fat as an energy source.
A healthy lifestyle actually has a side effect of
fat loss. If you don’t need to lose any weight, then you won’t. You
simply just feel better and become healthier.
I believe that around 40 to 50% of our calories should come from low-glycemic
carbohydrates, 25 to 30% of our calories from good protein, and 25 to
30% of our calories should come from good fat. You should eat five to
six small meals each day. Eat breakfast within one hour of awakening and
a meal or snack every four hours throughout the day to keep your
metabolism going and blood sugars stable. I find weighing foods is not
necessary, although reading nutritional labels is essential.
Don't get caught up in anything too
complicated—like weighing foods. Simply use your hand as a guide. The
palm of the hand (circumference and thickness) = 1 protein serving (red
meat—use ½ the palm of your hand). 1 fist (1 ¼ cups) = fruit serving
(carbohydrate) or vegetable serving (carbohydrate). Tip of the thumb (1
tsp.) = 1 fat serving.
A typical meal should contain two servings of carbohydrates (although if
you eat low-glycemic carbohydrates you really don't need to worry about
the quantity you eat--the more the better), one serving of protein, and
one serving of fat. If your body frame is large, you may need double
this amount. The important thing to remember is the fact that you should leave every meal or snack
satisfied--not hungry and not full.
Here are some principles to help you enjoy food and keep you on track:
Be careful not to consume high-glycemic carbohydrates. Recent research
reveals it would be best to avoid high-glycemic foods all together.
(read the discussion about the glycemic index).
Be creative with your snacks and be sure that they contain the right
balance of good carbohydrates, good fat, and good protein and do not
spike your blood sugar.
Always have healthy snacks readily available. If you don’t, you will eat
whatever is around when you get hungry.
Purchase low-glyemic nutritional drinks and bars that you can have
readily available at any time.
You will tend to have some withdrawal from the traditional high-glycemic
carbohydrates. This is because of what is referred to as a "Carbohydrate
Addiction". This actually leads to much of the overeating that many of
us experience. However, once you become consistent with this diet you
will feel much better with a marked increase in energy.
