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.

A-Salted?
Too much salt in the human diet has detrimental effects on health. For example, it raises the blood pressure, increasing the risk of a stroke. Many people in 'Western' populations, when they eat, automatically reach for the salt. Up to 20% of their total sodium intake, is added to food at the table. A recent study suggests that this added salt can reduce life expectancy (https://www.theguardian.com/society/2022/jul/11/adding-salt-table-food-linked-earlier-death-study ). The study was carried out on 500,000 middle-aged Britons. Adding salt to food at the table, may be a proxy for a less healthy lifestyle. It was found, however, that using the salt dispenser, knocked 2 years off the life expectancies of men and 1.5 years off women. This study did not include the seasoning, that was added in the cooking and/or manufacturing processes. Many low quality processed foods, include high salt levels as a 'taste enhancer'. Although the study has these limitations, it at least suggests that a modest reduction in sodium intake (by adding less or no salt to food at the table), would have a measurable health benefit. Go easy on that salt!
