What the flag wavers seem to overlook is the feedback loop that results in obesity. Excess consumption of sugar leads to an insulin spike, which subsequently results in low blood sugar, which causes a craving for more sugar, ad infinitum. All the while, the excess insulin affects the body's ability to use calories efficiently, which leads to obesity. So if you get onto that ride from hell, it can become self-supporting and addictive. Insulin resistance occurs whereby the reduction in insulin sensitivity causes the pancreas to over-compensate by releasing even more insulin. This leads to two common outcomes: diabetes, or obesity combined with high cholesterol and increased rates of heart disease.
Bottom line: accommodating people who are stuck in the feedback loop with all-around access to the very thing that is addicting and killing them is secondary to the 24/7 waving of the flag. It's like making alcohol readily accessible to alcoholics, wherever they may be, so that the draw is always there, unrelenting. It's like knowing there is a gambling problem among the population, but installing gambling arcades on every corner. Freedom. Ra ra.
I do not have an addictive personality and have better dietay discipline than most, and certainly everyone I know personally. However, there are some foods that I find hard to resist, and the only way I do resist them fully is by avoiding where they may be available. What favors are we doing to people with perhaps less discipline and who are already in the insulin feedback loop, by making fully accessible virtually everywhere within an arm's reach the very thing that draws them, despite their best intentions? The very thing that is killing them?
