...about and why is it so important? The science that has been produced in this area has come to the conclusion that the early human being had an omega 6 to omega 3 ratio of 3:1. With the changes in lifestyle and especially after the introduction of the food industry, which feeds animals with seeds, soy, flour (ie Omega 6), humans have been showing since 1960 (turning point), a ratio of 4 :1, and today 15:1 in Europe. In the US the ratio is 25:1. What's the problem with a 15:1 ratio? Our cells to summarize in a simple way can be compared to a filter. If this filter is clogged, nutrients have difficulty getting in and waste has difficulty getting out of the cells. This causes anomalies at the cellular level in the long term. A ratio of 1:1 or 3:1, as science says, is th...
