This blog may help people explore some of the 'hidden' issues involved in certain media treatments of environmental and scientific issues. Using personal digital images, it's also intended to emphasise seasonal (and other) changes in natural history of the Swansea (South Wales) area. The material should help participants in field-based modules and people generally interested in the natural world. The views are wholly those of the author.

Fishing For Relief?
Worldwide, Chronic Kidney Disease (CKD) affects about 700 million people. The condition can result in kidney failure and death, especially if dialysis is unavailable. Rather obviously, a simple means of lowering the risk of contracting CKD would benefit lots of folk (https://www.theguardian.com/science/2023/jan/18/scientists-eating-oily-fish-lower-risk-of-chronic-kidney-disease-omega-3-fatty-acids). Eating at least 2 portions of oily fish (e.g. Mackerel, Sardines and Herrings) each week, is linked to a reduced risk of developing CKD as well as a slower decline of kidney function. It now appears that higher doses of omega 3 fatty acids, from oily fish and other seafood, account for the link. No such link was seen, however, with omega 3 fatty acids derived from plants. Consequently, vegans would not benefit from the protective actions of omega 3 fatty acids.
