Our knowledge of nutrition is tightly controlled by professional bodies and by the messages the food industry wants us to believe. Much of what we've been taught to believe about food is has no basis in science, even though those who now claim to offer us "evidence Based advice" tell us that they have professional knowledge.
Finding a Heart Healthy Diet
When the dietary standards for most developed societies were written, they copied the American Standard Diet soon after 1980. The focus in the minds of the politicians who made that legislation was to recommend a "Heart Healthy Diet" often called the "Prudent Diet."
The Standard American Diet and it's Effects.
Sadly the recommended diet did not have any dramatic effect on heart health, or on the other problem, cancer. Instead, obesity increased, and a number of lifestyle diseases became common, making the health of all the nations in the English speaking world, and beyond, much worse. There is recognition of this reality. In South Africa, the language of recent guidelines has changed. In Brazil they have chosen to promote a simple ten step healthy diet guide.
Lipophobia and the Sugar Debate
A key message in the "Heart Healthy Diet" was to limit fat in the diet, particularly saturated fat. This meant by necessity, that people needed to eat more carbohydrate than was normal. It's also left most of us with a fear of dietary fat that isn't at all supported by science.
Our Hybrid Metabolic (Fuel) System
We've never been taught about a hybrid metabolic system we all have. The lipid metabolic system can fuel our bodies almost entirely with dietary fat. It's the metabolism we all used when we were being breast fed by our mothers. The glucose metabolic system can fuel our bodies almost entirely with glucose and carbohydrates.
The Obesidemic Environment and Commercial Influence
The current level of obesity in society isn't the fault of individuals. Our governments, and professional groups and industry have worked together to create an obesidemic environment. They might have begun with good intentions, but their actions have had unintended consequences.
Professionals Oppose the Paradigm
Today, with the Internet, it's become quite clear that there are many professionals who believe that the current dietary guidelines do not help community health. There is growing scientific evidence that a change in those dietary standards is badly needed. A growing number of professionals are openly saying so, sometimes at the risk of their professional status.
