I see that there's a new Vulnerable Group reared its head - or swished its little tails! - There are some genetically modified mice that are very vulnerable to becoming obese because of a mutation in a particular gene, reported here. Well I don't think we need to trouble ourselves about that particular vulnerability, though one feels sympathy for the mice having their genes damaged, apparently in the cause of providing some information for the drug industry to avail itself of in its never-ending trawl for profitable products to unload on innocent citizens. Unless we allow drug researchers or their mates who work in genetic engineering to interfere with our genes we are unlikely to suffer this genetic problem ourselves, or - perish the thought! - any of us is tricked into eating any of these GM mice and something untoward happens... (Memo: best to avoid eating GM foods, whether animal or vegetable, and best to avoid eating animals that have been fed GM crops. Since no one knows what could happen, the precautionary principle should be applied.)
The Vulnerable Groups in whom I am most interested are those who are vulnerable to becoming obese because of salt sensitivity or sodium retention. The groups of people vulnerable to salt are babies and children, people who take or who have taken certain prescribed steroids, including prednisone and prednisolone, or certain other prescribed drugs, women who take or have taken HRT or other oestrogen-containing drugs such as some contraceptive medications, people who take or have taken amitriptyline or other tricyclic antidepressants or some other psychotropic/psychoactive drugs, pregnant mothers, PMT sufferers and people who ate salt as children. These groups need to minimise their salt intake. They will lose weight easily if they eat less salt and salty food.
