With such a bewildering array of diets available, it is nearly
impossible for most of us to know how to eat in the healthiest way
possible. Much of this confusion exists because not one single diet
fits every person. For example, people with heart disease are urged
to follow low-fat diets; elite athletes focus on protein intake;
and, cancer patients are told to avoid foods containing chemicals.
Yet, when it comes to eating right, there are a few basic principles
of human physiology that hold true for all of us. Understanding
these principles-and experimenting with them a little-can help you
find a way to eat that best
promotes your own health.

The
Vital Role of Blood Sugar Control |
|
 |
| |
Optimum health can only be achieved when you consume a hormonally
balanced diet. This means maintaining a steady blood sugar
level by eating at the right times and consuming the right
amount of protein, carbohydrates, and fat with each meal and
snack.
Maintaining adequate blood sugar control, or glycemic control,
is much like keeping enough gas in your car so that it will
run. If your car runs out of fuel, it will stall. Similarly,
if your body does not have an adequate level of blood sugar
(the fuel that the body gets from food), you too will stall.
Classic symptoms of a low blood sugar level are headaches,
brain fog, sweet cravings, nervousness, inability to think
clearly, and even depression in some situations. For some
people, the problem goes unnoticed because there are no obvious
symptoms.
To ensure that you have an adequate blood sugar level, you
must eat the proper foods. Eating the right food fuels the
body by providing adequate blood sugar. If your blood sugar
level is low, your body will go into a predominantly catabolic
state, breaking down muscle, organ, and bone tissue in order
to keep the body going. At the same time, your immune system
may become compromised.
Clinically speaking, blood sugar control occurs when insulin
and glucagon (two hormones) are in balance. The pancreas produces
both of these hormones in response to the foods you eat:
- Carbohydrate consumption produces insulin, the hormone
responsible for storing fat (or producing energy).
- Protein consumption produces glucagon, the hormone that
promotes the mobilization and utilization of fat for energy.
- Glucagon works to counter balance insulin.
- High insulin is associated with virtually every disease
known to mankind, including cancer.
Eating more of one type of food over the other can create
a hormonal imbalance, which can cause illness. For example,
when excess carbohydrates are consumed, the body produces
excess insulin and little glucagon. As a result, more fat
is formed and stored, and your blood sugar level drops. In
an attempt to normalize the blood sugar level, the body initiates
a counter-regulatory process during which the adrenal glands
are stimulated to secrete increased levels of cortisol (the
primary hormone that regulates the immune system). Remember
that if the adrenal glands are stimulated over a prolonged
period of time-say, because you continue to eat too much carbohydrates
over protein-the ability of the glands to produce cortisol
will wane, eventually leading to cortisol depletion and adrenal
exhaustion/fatigue.
You can avoid creating a hormonal imbalance by eating some
protein. Glucagon is released when you eat protein, and this
hormone keeps insulin in check.
Of course, eating too much protein over carbohydrates isn't
good either. Eating an excess of protein can cause an unhealthy
state of high acidity, which adversely affects digestion and
overall health. The glycemic
index will help you understand how to easily create this
balance.

Glycemic
Index |
|
 |
| |
You can ensure that you are eating balanced meals by becoming
familiar with the
glycemic index of the foods you eat. The glycemic index
of a food refers to the rate at which that particular food
causes glucose (sugar) levels to rise in the blood. The higher
the glycemic index, the faster that food converts to blood
sugar. The faster a food converts to blood sugar, the more
insulin your body makes and the harder it is to maintain good
glycemic (blood sugar) control.
As a general rule, all "above-the-ground" vegetables-broccoli,
lettuce, cabbage, and the like-have a low glycemic index (less
than 80). All "below-the-ground," or root, vegetables-potatoes,
carrots, yams, and the like-have a high glycemic index (greater
than or equal to 80). Corn, rice, breads, pasta, bagels, and
all grains are other examples of carbohydrates with high glycemic
indices. Even certain juices and fruits like bananas are high-glycemic
carbohydrates. A healthy meal would include larger amounts
of carbohydrates with a low glycemic
index and smaller amounts of carbohydrates with a high
glycemic
index.
When choosing the correct proportion of carbohydrate to protein,
you must consider the carbohydrate's glycemic
index. If a carbohydrate has a high glycemic index, eat
about one portion of carbohydrate to one portion of protein.
For example, let's say that you want eggs and potatoes for
breakfast. Because potatoes have a high glycemic index, you
should eat roughly the same amount (by weight in grams, or
by portion size) of eggs as you do potatoes. However, if you
scrap the potatoes in favor of carbohydrates with a lower
glycemic index-such as green peppers, onions, and mushrooms-you
can increase your portion of carbohydrates by at least twice
that of the eggs (your protein).
In general, to maintain the optimum level of insulin to glucagon,
you should eat a diet consisting of approximately two parts
(or two grams) carbohydrates with one part (or one gram) of
protein. (Also keep in mind that 70 - 80% of your total carbohydrate
portion of each meal should come from foods that have a glycemic
index below 80.) The following is a good example of a glycemically
controlled, balanced meal:
Carbohydrates:
2 cups of fresh broccoli (lightly steamed) = 5.2 grams
1/2 baked potato (in skin) = 25.5 grams
1/2 cup boiled then mashed acorn squash = 10.7 grams
------------------------------------------------------------
Total carbohydrates = 41.4 grams
Protein:
3 oz. Chicken = 20 - 22 grams
Total grams for the meal:
41.4 grams of carbohydrates to 22 grams of protein
Carbohydrates-to-protein ratio: Approximately 2-to-1
Note: 1 - 2 ounces of nuts, seeds, or olives make a good
snack between meals. Also consider eating various glycemic
control (protein) bars, which are available at health food
stores.
Keep in mind, however, that individual dietary requirements
will vary depending on a person's activity level and age.
You will need to experiment to find the ratio of protein and
carbohydrate that works the best for you. In general, if you
feel mentally and physically alert throughout the day, this
is generally a good sign that you are eating frequently enough
and in the right balance. Please note that headaches, brain
fog, and shakiness are classic signs of low blood sugar. You
can avoid this-just take control!

Choosing
Proteins |
|
 |
| |
You should eat low-fat proteins more frequently than high-fat
proteins. Low-fat proteins include chicken, turkey, most fish,
tofu, tempeh, low-fat yogurt, and low-fat cottage cheese.
Other sources of higher fat protein are eggs, beef, pork,
lamb, cheese, nuts (almonds and walnuts), nut butters, and
certain seeds (sunflower, pumpkin, or sesame).

Where
Fats Fit In |
|
 |
| |
Fat is probably the most maligned, misjudged, and misunderstood
of all the macronutrients. In truth, the body needs healthy
fats, called essential fatty acids, in very small amounts
to maintain many life-sustaining physiological functions.
Good fats are the building blocks for hormones and cell membranes,
and are responsible for healthy nerve conduction. Moreover,
essential fatty acids eaten in small amounts help us to control
our weight by slowing down and regulating the rate at which
sugar (glucose) enters the blood stream. This controlled release
of glucose helps you avoid getting a quick sugar rush and
further enhances good blood sugar control.
Essential fatty acids are commonly found in fish, seeds,
nuts, and plants. Olive oil, canola oil, flaxseed oil, almonds,
and avocados are examples of other healthy sources of fats.
Omega-3 oils from fish (salmon and sardines) or fish oil supplements
are also healthy essential fats. Be aware, however, that there
are fats that are potentially harmful to the body. Margarine
and other hydrogenated oils are potentially harmful, for example,
because they are trans-fatty acids. Trans-fatty acids have
been artificially altered to preserve their shelf life-a process
that makes these acids harmful to your cells. Trans-fatty
acids resemble essential fatty acids, making it difficult
for cell membranes to distinguish the two kinds of fat apart.
However, when trans-fatty acids do enter a cell, they cannot
perform the normal functions that essential fatty acids do,
thus opening the door for significant health problems.
Saturated fats are also potentially harmful to the body.
They are found in red meats and dairy products like cheese
and milk. Like trans-fatty acids, saturated fats should be
eaten less frequently than essential fatty acids.

Eating
Smart |
|
 |
| |
Practically speaking, following some simple rules of eating
can help you regulate your blood sugar level
Rule of 5 - Eat five times a day. Eat a balanced breakfast,
lunch, and dinner, and have two small snacks-one in the afternoon
and one around bedtime-every day.
Breakfast is the most important meal of the day; after all,
you fasted all night. To maintain a balanced blood sugar level--thereby
giving yourself energy throughout the day--try to make the
time to prepare a balanced meal in the morning. After four
to six hours, you will need to eat another balanced meal or
snack to replenish yourself and keep your blood sugar level
steady.
Eat before you become hungry. Unfortunately, many people
do not think about food until they are hungry. By that time,
they are running out of fuel (i.e. blood sugar may already
be low). Skipping meals also causes a low blood sugar level.
The longer you wait between meals, the longer you will be
in a catabolic state. This in turn places more stress on your
hormone and immune systems.
Eat balanced meals and snacks. To recap, a balanced meal
or snack consists of two parts carbohydrates and one part
protein. For example, a balanced breakfast might consist of
low-fat yogurt or cottage cheese (the protein) and your favorite
fresh fruit (a carbohydrate). You might also combine protein
sources like eggs, chicken, or turkey sausages with carbohydrates
like fresh fruit and a small amount of potatoes or toast.
Again, avoid eating a large amount of carbohydrates without
protein. Eating just carbohydrates will produce a sugar rush.
An hour or two later, your blood sugar level will drop. As
a result, you will likely feel sluggish or irritable and may
have difficulty thinking clearly. Eating a balanced meal (with
a small amount of fat) will help you avoid the sugar rush
and prevent the peaks and valleys of blood sugar swings.
Eat organic foods. One way to improve your nutritional status
is to eat organic foods, which are richer in nutrients than
commercially grown foods. Studies have shown that organically
grown food contains a minimum of 50 - 100% more nutrients
than commercially grown foods. (In fact, some commercially
grown vegetables virtually lack essential minerals.) Eating
organic foods also helps you avoid consuming the toxic pesticides,
antibiotics, hormones, and herbicides that are found in commercially
grown foods. Be aware, however, that organic foods may contain
harmful organisms. Likewise, commercially grown foods must
be cleaned well to remove any pesticide residue. So, be sure
to wash your food thoroughly.
- To clean your vegetables:
- Put 1/4 - 1/2 cup of white, distilled vinegar into a bowl
of water.
- Place the produce into the bowl.
- Soak for 20 - 30 minutes.
- Rinse the produce several times to remove the vinegar
and drain.
Store the produce in Tupperware or plastic bags in the refrigerator;
this will help maintain the food's freshness up to four more
days. Produce that is prepared in advance this way makes an
excellent ready-to-eat, nutritious snack. As an extra precaution,
equip your kitchen with separate cutting boards-one for meats
and one for vegetables-to avoid contamination of produce with
harmful bacteria, which are often found in meats. All cutting
boards and knives that come into contact with meat or poultry
should be thoroughly washed.

Drink
Sufficient Water |
|
 |
| |
Drinking enough water is vital for maintaining your health.
Water is the substance that bathes each of our cells, removes
waste products, and assists most biochemical reactions in
your cells. Unfortunately, most Americans do not drink enough
water. As a result, dehydration is one of the more common
nutritional deficiencies in the United States. Clinically
speaking, when a person is chronically dehydrated, the thirst
centers of the brain stop sending the signals that indicate
the need for water. Most people must force themselves to drink
pure water for about one month to reestablish the normal firing
of these nerve centers. Once you rehydrate yourself, however,
the normal thirst signals will return.
The key to adequate hydration is to drink pure water. Coffee,
tea, or soda dehydrates us even further, and fruit juice is
no substitute for pure water. Most people need a minimum of
eight 8-ounce glasses of pure water each day. This ensures
good digestive functioning, good nerve conduction, and the
elimination of toxins. It's also best to drink a minimum of
8 to 16 ounces of water within 30 minutes of waking up, since
you become slightly dehydrated from breathing at night . You
should also drink water a minimum of 30 minutes before a meal
to maintain the level of stomach acid and promote digestion.
Avoid drinking anything more than a small amount of fluid
while eating, since this can dilute stomach acid and impair
digestion and absorption in some people.
