Since the early 1980s food trends have gradually begun to change, with the introduction and fast popularization of processed prepackaged convenience foods. With this popularization, these foods also increased the consumption of high amounts of sugar, sodium, and high-fat foods which have a lower nutrient-density value that can have great adverse effects on health.

Due to the higher demand for processed prepackaged convenience food such as beef in your fast food burger, farmers began to industrially farm livestock to produce more meat to meet the food industry's demand. To meet the demands farmers began to feed livestock corn, soy, and grain. Corn is the most used animal feed in the United States. Compared to grass-fed beef, grain-fed beef was higher in saturated fatty acids along with a less favorable omega fatty acids profile, highlighting the imbalance of nutrients in these kinds of foods.
