Looks like a good, well-balanced diet,
does it not? No, apparently this pyramid seems to have some
controversial features; it encourages the use of calorie-rich
vegetable oils and discourages eating potatoes and white rice. The
USDA’s pyramid implies that all fats are dangerous and most
carbohydrates are safe. In contrast to this finding, more recent
research has shown that carbohydrates can be as deadly as fats.
Another pyramid of recent origins, devised
by Dr. Walter Willett and other staff at the Harvard School of Public
Health, promotes the message, “Eat, drink and be healthy.” This
new pyramid is called “The Healthy Eating Pyramid;” it breaks up
groups of fats or carbohydrates or proteins to highlight the best and
worst sources of those nutrients
Scientists have known since the 1960’s
that the fat in red meat and dairy products can raise cholesterol
levels and promote coronary disease. Studies have shown that unlike
butter and lard, the oils found in fish, nuts and vegetables help
protect against heart disease.
For some time now, food-makers have
realized the potential of low-fat processed foods. Cereal grains are
much more appealing when they are puffed, sweetened and put into a box
with a picture on the front and a toy inside, and you can charge more.
Low-fat cakes, cookies and snacks flooded the market in the early
1990’s, and consumers simply added them to what they were already
eating. Consumers assumed that anything low in fat must be harmless.
While the government health organization promoted lean meats and
low-fat dairy products, it neglected to think of snacks.
The calories and the way carbohydrates are
digested are the problems. Whole grains break down slowly in the
digestive system, but refined grains flood into the bloodstream as
glucose. If the glucose is not used to fuel activity, the body
produces a burst of insulin which goes out of circulation and goes
into fat and muscle cells for storage. A diet rich in refined
carbohydrates and simple sugars can erode the system. Cells become
more resistant to insulin and force the body to produce it in even
greater amounts. Eventually the system breaks down and results in
diabetes and fosters heart disease. An occasional glucose surge can be
alright for a lean, active person, but it adds fat to an inactive
body.
Weight management is critical. Daily
exercise and weight control are basic to good health. For most people
the best strategy is to boycott junk food. If you give up processed
foods in favor of whole foods, you can shed several hundred calories a
day. According to Dr. Willette, even the baked potato is a better
nutritional bargain than almost anything that comes in a package. A
baked potato with its skin on provides a full belly, vitamins,
minerals, and fiber - 150 calories. Whereas a bag of chips can carry
about 500 calories.
Eat plenty of vegetable - the USDA
endorses them. When you eat plenty of vegetables, the healthful diet
starts to look different. The Asian diet and the traditional
Mediterranean diet abound in fish, nuts and olive oil, and both the
Asian and Mediterranean diets are considered models of good eating.
Both diets rely on plants and fishes for fat. Both include some
refined grains, but neither treats cinnabuns as a food group.
You need to devise an eating plan that
embraces healthy cuisines and discourages excess food intake. You can
enjoy good carbohydrates (whole-grain foods) and good fats (plant
oils). Fast-burning carbohydrates are contained in red meat. In the
Healthy Eating Pyramid, nuts and legumes are at the top of the
hierarchy, followed by fish, poultry and eggs. Dairy products can be
optional if replaced by a calcium supplement.
There are critics of the Healthy Eating
Pyramid, but it is considered a definite step in the right direction
by many. It may take more than a healthy pyramid to improve your diet,
but if you are aware of the facts and are aware that eating well is
more fun than eating badly, it is a start in the right direction.
So, after all the research, new discoveries,
and controversies, what should we do? My suggestions is to stay away
from prepared, packaged foods and “Eat, drink and be healthy!”
