All fish contain more omega 3 than omega 6. I looked up shark fish, and it comes under the ‘white fish’ category so the ratio of 3:6 is probably in the region of 10:1, although I couldn’t find the exact figure. (Swordfish has 800 mgs of omega-3 and 30 mgs of omega-6 per 100g, and I would imagine that shark fish is similar).

The main drawback of shark fish is that it has one of the highest levels of contaminants (.979ppm compared to .391ppm in tuna and .001ppm in shrimp).
Worryingly here are some of the recommendations from the UK Scientific Advisory Committee on Nutrition about eating fish when trying to get pregnant, or when breastfeeding:
Shark, swordfish and marlin: do not eat these if you are pregnant or trying to get pregnant. All other adults, including breastfeeding women, should eat no more than one portion per week. This is because these fish can contain more mercury than other types of fish, and this can damage a developing baby’s nervous system.

The easiest way of improving the omega-3 to omega-6 ratio in one’s diet is to reduce the amounts of omega-6 foods by cutting back on vegetable oils which are particularly high in omega-6 fats.

Very interesting articles indeed !

In Southern India, Shark fish is the Grandmothers recipe for pregnant and nursing mothers. Wondering if it contains more Omega 3 or 6.
