The human diet
The Evolution of the Human Diet
The examination of the human diet and its evolution reveals that up until the early 1900’s, the human diet only contained about 25% total fat. Since that era, eating habits have slowly begun to change, a result of the industrialization and commercialization of our food supply and rapid population growth. Today, the western diet has increased the average fat intake to a staggering high of 40%.
Not only has the fat intake drastically increased, but the ratio of saturated fat to polyunsaturated fat has doubled. Humans are now consuming twice as much saturated fat as they once were just a century prior. To make matters worse, the ratio of Omega-6 to Omega-3 has widened. What was once a 1:1 Omega-6 to Omega-3 ratio is now a 20:1 Omega-6 to Omega-3 ratio. Many believe this shift in our diet puts us as a risk for many "western" illnesses. Taking into consideration the change in our Omega-6 to Omega-3 ratio and the changes in the immune system response that is created, it is easy to understand the increased risk in chronic disorders of the heart, skin, joints and brain. A 20-fold increase in pro-inflammatory Omega-6 versus Omega-3s is bound to have a negative impact.
It is easy to see that we have two options, decrease our consumption of Omega-6 fats or increase our consumption of Omega-3 fish oil. Fortunately, today we have more options than ever before to include high concentrate Omega-3 fish oil into our diet. Some of the benefits from a properly balanced ratio are:
- Improved blood flow
- Protection of the blood vessel walls
- An increase in “good” HDL Cholesterol
- Helps to maintain a normal heart function
- Support immune system responses in our joints and skin
- Positive effects on development, maintenance and performance of our brain, eyesight and nerves.
