With industry's sales and marketing machines cloaked in mantles of charitable virtue, no wonder most Americans don't realize that the junk that passes for food is in fact the biggest contributor to our health crisis, and the junk that passes for medicine keeps us just well enough to continue to spend on both the food and the medicine.

If we limit our sight to individual players, we'll never see the big picture. The issue is a systemic one, maintained by interconnected actors, all acting in their self-interest to further their goals. The trouble is not, or not always, the actors themselves, or their intrinsic motivations. Instead, it's the overarching goal of the entire system that's at fault: corporate profit above public health.

Even rational, data-driven scientists could be sent into prolonged states of hysteria when presented with evidence that their favorite foods might be killing them.

This is also the case with our disease-care system: it focuses on treating symptoms as if they were root causes, and as a result, it tends to choose interventions that completely ignore the true root causes and thus make it highly likely that symptoms will reappear.

We don't need to know the effects of single agents on health, because this is not the way that nature works. Nutrition has a wholistic effect on health; one that we consistently miss and misinterpret when we focus on isolated nutrients.

The problem is that we are asking the wrong questions - questions based on a fundamental misunderstanding of the wholistic nature of nutrition. We're asking, "How much vitamin C are we getting?" when we should be asking, "What foods should we be eating to support our bodies' ability to maintain health?

I have heard one doctor call high-protein, high-fat, low-carbohydrate diets “make-yourself-sick” diets, and I think that’s an appropriate moniker. You can also lose weight by undergoing chemotherapy or starting a heroin addiction, but I wouldn’t recommend those, either.

Americans love to hear good things about their bad habits.
