My girl asked me one day:
"Mummy, is fish smart?"
"Hmm.. I don't think so. They have very small brains."
"Then why did Grandma say I must eat fish to be smart?"
That really cracked me up! ;D
The old wives' tale that eating fish is good for brains has its place.
I am, however, more concerned about the level of mercury in fish as nowadays, our rivers and seas are superbly toxic what with oil spills, toxic waste and chemicals conveniently dumped into our global waters. I have a friend who used to work off shore on an oil rig and he said that whatever liquid chemicals that weren't needed anymore were poured into the sea-- on a daily basis!
What is considered a dangerous level of mercury in our bodies?
What is considered a dangerous level of mercury in our bodies?
"Most non-exposed people have mercury levels of 0 to 2 (all blood measurements are in micrograms of mercury per deciliter of blood, or ug/dl). Levels above 2.8 ug/dl are required to be reported to the Health Department. This test can be influenced by eating fish, because fish (particularly certain deep sea fish) may contain mercury."
So I compiled a list of fish which has the lowest to the highest content of mercury as a guideline. Hope you'll find it helpful.
