Why The Food Pyramid Failed?
The following is an article written by by Dr. Prab R. Tumpati, MD published in 4Health Magazine.
In May 2011, the USDA released a graphic called “My Plate” to help people choose what foods to eat. This new guideline is meant to replace the old “Food Pyramid» that many people grew up with. Remember the triangle shape with the bread, cereal, and rice at the bottom and the fats and oils to be «used sparingly» at the top? This useless and misleading food pyramid,which has been confusing consumers for over 25 years, has advocated a philosophy of eating more grains and other less “fatty” foods.
What the Food Pyramid failed to do was to differentiate simple versus complex sugars. It also placed undue importance on grain-based products. Grain-based “simple carbohydrates” such as breads, potatoes, rice, cereal and pasta, although often low in fat, also rate high on the glycemic index. That means that they break
down quickly in the body, overwhelming the blood with sugars and potentially leading to a phenomenon called “insulin resistance.» Affecting up to one in every three Americans, insulin resistance is very common and can lead to difficulty losing weight, pre-diabetes, or type II diabetes, heart disease and other long-term health problems associated with obesity. With the new «My Plate» guidelines and some other tips, more Americans may be able to avoid these unhealthy complications.
WHAT IS INSULIN RESISTANCE?
Insulin resistance is a condition in which the body produces insulin, but does not use it properly.
Insulin, a hormone made by the pancreas, helps the body use glucose (natural sugar) for energy. When people are insulin resistant, their muscle, fat, and liver cells do not respond properly
to insulin. As a result, their bodies need more insulin to help glucose enter cells. The pancreas tries to keep up with this increased demand for insulin by producing more. Eventually, it becomes overworked and may no longer be able to meet that demand. Excess glucose builds up in the bloodstream, setting the stage for diabetes. Many people with insulin resistance have high levels of both glucose and insulin circulating in their blood at the same time. Learning about insulin resistance is the first step toward making lifestyle changes that can help prevent diabetes and other health problems.
TIPS FOR AVOIDING INSULIN RESISTANCE
According to the American Diabetes Association,nearly two million new cases of diabetes were diagnosed
in people aged 20 years and older in 2010.Since the grossly misleading food pyramid was introduced.
Could High Insulin Make You Fat? A New Study Says Yes
When we eat too much, obesity may develop as a result of chronically high insulin levels, not the other way around. That’s according to new evidence in mice reported…
