Health effects
Fiddleheads contain various vitamins and minerals, as well as omega-3 and omega-6 fatty acids. They are a source of antioxidants and dietary fibre.[2] They are low in sodium, but rich in potassium, which may make them suitable for people who need a low-sodium diet.[4]
Fiddleheads may harbour microbes, and should be washed and cooked before eating.[2]
Many ferns also contain the enzyme thiaminase, which breaks down thiamine. This can lead to beriberi and other vitamin B complex deficiencies if consumed to excess or if one's diet is lacking in these vitamins.[5]
Further, there is some evidence that certain varieties of fiddleheads, e.g. bracken (Pteridium genus), are carcinogenic. Ostrich fern (Matteuccia struthiopteris) is not thought to cause cancer,[6] although there is evidence it contains an as yet unidentified toxin.[7]
咱这的蕨菜是Ostrich fern,无害滴。但不能生吃,必须好好洗,开水抄过才能吃。自己看吧:http://www.hc-sc.gc.ca/fn-an/securit/kitchen-cuisine/fiddlehead-fougere-eng.php
