Some anecdotes. In some traditional cultures I am aware of (Korea, high-altitude eastern Himalayas), fern consumption tends to be, but is not always, linked to the start of spring (end of winter) as the ferns are often the first things to emerge from snow, and only the smallest fronds and not the mature fronds are eaten. This may have a bearing on carcinogenic capacity. I've personally eaten a lot of fern in Yunnan. However, stomach cancer is highest in the world in Korea and highest in men and they are not huge fern eaters. One assumes the projected causes would be behavioral (high alcohol liquor) and dietary (meat, kimchi = lowers stomach pH + chilli to irritate stomach lining) in conjunction. Could have easily been the same in the article's sample size of one. In China edible ferns are referred to as 蕨菜 (jue cai). They're quite tasty stir-fried with tomato and garlic. Tell you what though - fern spori are scary looking under a microscope! I just did some research on raspberries (commercial berries are notorious for pesticide residue) and apparently hydroponically grown berries are roughly equivalent to soil-grown berries in blind student taste tests and, despite soil-grown being technically sweeter if you do the chemistry, this is theorised as being due to water-related stress (so you could perhaps emulate this with a more sporadic hydroponic watering schedule if you want extra-sweet berries). In short: no reason not to grow at home, if you are familiar with the basics. https://www.scirp.org/pdf/FNS_2015121614300010.pdf https://www.scirp.org/pdf/FNS_2015121614300010.pdf https://file.scirp.org/pdf/FNS_2015062414290599.pdf https://file.scirp.org/pdf/FNS_2015062414290599.pdf
