Top Ten Things to Know About Food and Diet
by Ronald Steriti, ND, Ph.D.
During my first “Ask The Naturopath” TeleClass several
questions were asked about diets.
This Top Ten List was written to answer some of these questions and help sort
out some of the confusing and often contradictory information that is available
about food and diet. This List begins with the basic categories of foods and
then introduces several popular diets.
Carbohydrates
Carbohydrates include starch which is found in grains, cereals, and vegetables.
Sugar, bread and pasta are also carbohydrates. Carbohydrates are broken down to
form energy in the body. If there is no need for this energy, the carbohydrates
are made into fats which are stored for future use.
Simple Carbohydrates
Simple carbohydrates include monosaccharides and disaccharides. The word
saccharide is derived from the Latin word meaning sweet. Mono means one, and di
means two. Therefore simple carbohydrates have either one or two “sweet”
molecules bound together. Sugar (sucrose) is the most common simple
carbohydrate. Other simple carbohydrates are galactose, fructose, maltose and
lactose.
Complex Carbohydrates
Starch is a complex carbohydrate found only in plants. Starch is formed from
polysaccharides, which are long chains of “sweet” molecules (poly means many).
Many of the ailments of modern man, including diabetes and obesity, are believed
to be caused by the introduction and widespread use of simple carbohydrates such
as white sugar and white bread.
Protein.
Protein is made from amino acids which are the building blocks of the body.
Although meat and fish are the most well known sources of protein, blue-green
algae contains more protein per gram (and also is high in many B vitamins) which
is why it is included in many protein powders. Protein is also found in beans,
lentils, tempeh, oats and other grains. Many protein powder supplements are made
from rice, soy and whey.
Fats
Fats are composed of carbohydrate chains (called fatty acids) attached to a
glyceride molecule. They are used to store energy in the body. Oil is a liquid
form of fat. The omega-3 and omega-6 oils are also called essential fatty acids
because the body needs them to remain healthy. The brain is composed almost
entirely of essential fatty acids. Clinically, essential fatty acids (like flax
and borage oils) have a marked anti-inflammatory effect on the body.
The Balanced Diet
Traditional naturopathic diets stress a balanced ratio of fats, carbohydrates
and protein. These diets are often called 30/30/40 diets referring to the
percentages of fats, carbohydrates and proteins. This is similar to the diet
recommended by Barry Sears in his book The Zone Diet. For many people this means
dramatically reducing the number of carbohydrates (such as bread, sugar and
pasta) and increasing the amounts of protein and fats.
The Low Carbohydrate
Diet
Dr. Atkins in his book Dr. Atkins’ Diet Revolution advocates a diet very low in
carbohydrates which is mainly used to lose weight. In his book he advocates high
protein meals with an emphasis on meats. If followed strictly, his diet will
result in what he terms “benign dietary ketoacidosis” with accelerated weight
loss.
Glycemic Index
The Glycemic Index refers to the rate blood glucose levels rise after certain
foods are ingested in comparison to an equivalent amount of pure glucose
(sugar). Sometimes pure glucose is replaced by white bread as a standard. Foods
with high glycemic indexes include corn flakes, instant and regular potatoes,
honey, bread and rice. Interestingly ice cream has a fairly low glycemic index.
This is due to the fats which tend to slow blood sugar rises.
The Blood Type Diet
Dr. Peter D'Adamo is a naturopathic doctor that has thoroughly researched the
relationship between human blood types and diet. His book "Eat Right For Your
Type" was a best seller. Many people with chronic illness find that their
symptoms improve when following his recommendations and return when they go back
to their old eating habits. Dr. D'Adamo has an extensive web site at http://www.dadamo.com
Low Fat Foods
I
would like to end with a caution about many of the “low fat” products currently
available. The term “low fat” means that the product has much less fat than the
regular brand. It has nothing to do with either diets or losing weight. In fact
many of these products are high in carbohydrates which may cause exactly the
opposite. Labels should be read carefully.
Unfortunately no one has designed a “high health” label, and even if
they did there most likely would not be agreement as to which products are
healthy.
