Outline of proposed changes
I have revised and expanded the History section of this wiki. I modified the original statement that attributed sugar, sodium, and high fat as the sole culprits for its unhealthiness. I made this alteration because these are essential nutrients that should not be vilified due to a lack of context. What makes them unhealthy is their overabundance when combined with a lack of other essential micronutrients such as vitamins, minerals, and a well-balanced fatty acid profile. I included an NIH source on the fatty acid composition of grain-versus grass-fed beef to support this revision.

Furthermore, I introduced a historical perspective on the evolution of the US food industry, highlighting its shift towards faster and more convenient food production. This change in consumer demand led to a higher demand for meat. In order to meet this growing demand farmers increased sought livestock that could yield greater quantities of meat for profit. Consequently, the preference for grain feed emerged as a solution, as it facilitated livestock in producing more meat for sale. This, in turn, connects back to the comparison between grain-fed and grass-fed livestock, demonstrating that the deviation from a natural diet resulted in a decline in nutrient density and a less favorable fatty acid profile. I referenced USDA data to illustrate that the majority of meat production in the US relies on corn (a grain) as livestock feed, underscoring the prevalence of grain-fed livestock in the US.
