Something to consider about your past experience:
Your disagreement with fish oil may in part be due to the quality of fish oil you were using.
Especially with fish oil, it is important to account for quality. Not only to be certain that the mercury levels are indeed safe, but also to avoid fish oil that may be rancid or poor quality due to less than stellar manufacturing processes.
Not all fish oil is created equal in this regard. If the fish oil you were using was in fact rancid or partially rancid due to poor quality assurance, it would have made your stomach upset, given you nasty fish burps, and your skin would smell like fish over prolonged use. Anything you can buy at an average grocery store/OTC pharmacy will give these results.
Try fish oil that is labeled as molecularly distilled or pharmaceutical grade, as it will remedy these problems. There are also fish oils that are flavored if you do not like the smell/taste. One good combination of both of these is Barlean’s fresh catch.
However, I do wonder if some of these problems may come up in the soylent oil mixture, especially considering that cost seems to be a big deal for proponents and high quality fish oil is not particularly cheap. Canola oil also has a bad reputation for going bad/degrading over short periods of time, often times when it hits the shelf it has already gone partially bad. By bad, I do not mean unsafe, but many of the health benefits have diminished.
I’d like to hear thoughts on this.
