cliff notes:

- zuviel EPA/DHA ist ungesund, da es das immunsystem schwächt
---->
Thies and colleagues examined the 12-week effect of various fatty acid
supplement mixes on healthy subjects [19]. Various blends of placebo oil and oils
rich in ALA, GLA, AA, DHA, or EPA (720mg) + DHA (280mg) were compared. Total
fat intake from the 9-capsule dose was 4 g/d. The EPA/DHA treatment was the
only one that had a negative effect on immunity, significantly decreasing natural
killer cell activity by 48%. This effect was reversed after 4 weeks of ceasing
intake of the supplement.




- Auch Pflanzenöl kann in EPA umgewandelt werden
----->
As a side note, there’s a widespread belief that ALA from flaxseed is worthless
for increasing EPA/DHA since the conversion is inefficient. However, Harper’s
team recently saw 3g ALA/day (from 5.2g flaxseed oil) raise plasma EPA levels by
60% at the end of a 12-week trial




- Fazit: Fischöl ist kein Wundermittel, und mehr hilft nicht mehr. Der Abnehmeffekt
ist zu vernachlässigen. Viele verschiedene Fette zu sich zu nehmen ist besser
als 50% fischöl am tag aus der Flasche zu trinken.
------->
To sum everything up, fish oil has health benefits, as well as potential risks. It’s
certainly not a matter of more-is-better. It might have minor fat loss effects in
the obese and overweight population, but their fat loss effect in general is far
from conclusively established. Get a variety of fats in your diet, and get them
from whole foods whenever possible. Fish oil is merely one of many agents that
can contribute to optimal health within the context of well-balanced nutrition.
Keep it in perspective, and keep your eye on the facts.
