Carbohydrates, Proteins, and Hidden Fats
is popular search term and you should find the information you are seeking here. Please drop me a line if you need more on .
Recent TV news showed that various food brands are offering
low carbohydrate foods due to public demand. That just shows
how poorly informed the public can be.
The Mayo Clinic (http://www.mayoclinic.com/) tells us that
"Every day your body requires certain nutrients, such as
carbohydrates, fats and protein, to function properly. Too
much of one nutrient or not enough of another can influence
your health."
Encyclopedia Britannica (http://www.britannica.com) tells
how carbohydrates can be classified, but they are all
described as molecules of Carbon, Hydrogen, and Oxygen.
"Carbohydrates are the most abundant molecules in all
biology."
Carbohydrates and oils are the means that plants store
energy. Few plant fats are saturated.
Fats are also compounds of Carbon, Hydrogen, and Oxygen,
but in more complex structures than carbohydrates. The more
structural bonds, the less liquid is the fat at room
temperature. Such liquid fats are called oils.
Hydrogenating oils creates more hydrogen bonds to make
liquids into soft or hard fats. These trans-fats are bad
for cardiovascular health. The "essential fatty acids" are
the ones that the human body cannot create from other
foods, such as proteins.
Proteins have many structures, but are mostly composed of
Carbon, Hydrogen, Oxygen plus Nitrogen. The essential amino
acids are those proteins which the human body cannot create
from other foods.
Of course, foods also contain essential vitamins and
minerals. Supplements of these can be beneficial, if not

High / Low Carbohydrate / Protein diets really miss the
target. Once minimal needs of each food type are met, the
real issue is high or low calories compared to those used.
If you eat more than your exercise can burn, you gain
weight, and vice versa.
Carbohydrates as sugars are fine as nature provides them,
but not as refined and concentrated by humans. Like any
source of calories, excess consumption leads to body fat.
The details will vary, but a five pound bag of fresh fruit
contains fewer calories than a typical candy bar.
Supposed high protein diets are often filled with hidden
fats. For example, consider ground beef.
Center for Science in the Public Interest, with reports
on-line at www.cspinet.org, tells us "USDA allows ground
beef labels to make claims that would be illegal on other
foods." "Ground beef accounts for 45 percent of the beef
sold in the U.S. and it adds more fat -- and more artery-
clogging saturated fat -- to the average American's diet
than any other single food." "The USDA allows no more than
10 percent fat by weight in most foods that are labeled
'lean.' But the USDA allows ground beef that is up to 22.5
percent fat to be called 'lean.'" Of course, that fat is
"saturated".
In contrast, protein from plants, such as grains and
legumes, has much less fat than ground beef and none of it
is saturated. Tempeh, an Asian food made from whole soy
beans with careful fermentation, has more protein than an
equal amount (volume or weight) of ground beef, and also
contains all the essential amino acids.
So try this for healthy diet rules. Eat all the vegetables
and fruits you can stand, but without sauces, dressings,
added sugar, butter, margarine, or cheese. The same applies to
grain foods, such as whole grain breads and pastas. Get at
least some of your proteins from plant sources. Avoid all
foods fried in fat or oil.
I lost weight and one third of my blood cholesterol by
reducing my beef and pork consumption, increasing my use of
broiled and baked fish and chicken, and learning about soy
foods that are now available in North America.
Even Ph.D. scientists can mis-lead themselves with wishful
thinking. A former colleague of mine was often heard to
describe his high protein, low carb diet in terms of complex
biochemical theories, yet he was always at least 100 pounds
overweight. He also ate and drank about three times as much
as I did at shared meals. Get Real!
