I think the salt is somewhat over-emphasised as an unhealthy food constituent, though the likelihood is that most of us eat more of it than is strictly good for us. Personally, I don’t consume much salt because I don’t eat much processed food (where most of our salt comes from) and I add little, if […]
Sunlight
As a big believer in the health-boosting potential of sunshine, I do what I can to get my fair share of this free commodity. One a recent trip to the Algarve in Portugal, I made being out in the sun a priority. I have olive skin, which means, as long as I don’t go mad, […]
Diabetes/Metabolic Syndrome
Back in December I reported on a study which found that supplementing men with an extract of green tea led to a significant reduction in their weight, waist size and ‘fat mass’. The extract in question, which goes by the name of epigallocatechin-3-gallate (EGCG), is believed to boost metabolism by stimulating the burning of fat […]
Children's Health
I love being out in the sun. And not just because I like it, but also because of the abundant evidence linking sunlight exposure with a reduced risk of conditions such as cancer and multiple sclerosis as well as improved physical and psychological functioning. And it’s free. And I like sporting a tan. I recently […]
Diabetes/Metabolic Syndrome
Variously on this site I, and quite a few commentators, have expressed concern for the conventional vogue of advising a diet rich in carbohydrate. Excesses of carbohydrate can cause gluts of the hormone insulin which in turn can predispose us to all sorts of problems including weight gain, type 2 diabetes, metabolic syndrome and cardiovascular […]
Exercise and Activity
I see a lot of different health issues in practice, and these can broadly be divided into what you might call ‘primary’ and ‘secondary’ concerns. I see primary concerns as the sort of things that cause individuals to make appointments to see me. Common example include fatigue, irritable bowel syndrome, asthma and eczema. On the […]
Food and Medical Politics
If I were to summarise what is conventionally regarded as a ‘healthy’ diet, I’d say it would be one which is low in fat, and rich in carbohydrate, including fruit and vegetables and fibre. I don’t particularly have much enthusiasm for such as diet myself: while I’m a general fan of fruit of veg, I […]
Sleep
While sleep can seem like ‘wasted time’ to a lot of us, the reality is that it plays a critical role in health and wellbeing. Not so long ago I wrote about a study that found a correlation between reduced sleep over time and an increased risk of death, particularly from cardiovascular disease. Other studies […]
Children's Health
Over the years, I’ve spoken to or have been consulted by a fair few people who, by their own admission, don’t have the best eating habits. A quite common picture I see involves the skipping or breakfast, a sandwich-centric lunch, followed by general overeating in the evening. This will usually entail some snacking before supper […]
Exercise and Activity
I was in a meeting today, and the subject of weight loss came up. As some of you may know, I have previously written about how exercise tends not to be particularly effective for those wishing to shed pounds. I made the point that those wanting to lose weight would do better to, among other […]
