1. Processing removes essential nutrients and fiber from foods. Almost 3/4 of Americans don't get RDA amounts of magnesium and zinc due to their refined food diets. These nutrients are required for health.
2. Processing adds sugar and preservatives that have a negative impact on health. The former head of the FDA said that if table sugar came up for review today as a food additive it would be denied due to its negative impact on human health. Many of the preservatives have been shown to be carcinogenic or have other unhealthy impacts on human health.
3. The additives and processing negatively impact insulin sensitivity and increase the caloric content of the food. This leads to overconsumption of calories and obesity, a leading cause of death in the United States.
