Cholesterol and Statins
Dairy products are, from a conventional nutritional perspective, very much a ‘double-edged sword.’ On the one hand, we are told, they provide the body with valuable calcium for healthy bones. On the other, they can be rich in ‘artery-clogging’ saturated fat and cholesterol. The answer, we are assured, it to consume dairy products in low-fat […]
Cholesterol and Statins
What is deemed a desirable cholesterol level in the mind of many health professionals has a lot to do with the opinion of panels of ‘experts’ who, essentially, tell doctors what to think and how to manage their patients. One such endeavour in the US is known as the Adult Treatment Protocol (ATP), which itself […]
Cholesterol and Statins
I don’t believe bread, as we commonly eat it, is a healthy or wholesome food (far from it). And last year I was surprised to read a ‘review’ lauding the nutritious attributes of bread and lamenting the fact that, here in the UK, bread consumption is declining. The review was authored by a scientist connected […]
Brain and Behaviour
I came across this report recently of a study which found that stopping men sleeping for a night led to them choosing bigger portions of ‘energy-dense’ food at a buffet [1]. Previous work from the same group at Uppsala University in Sweden found that sleep deprivation caused greater activity in the parts of the brain […]
Food and Medical Politics
I noticed yesterday that a certain study [1] concerning artificial sweeteners had got some press. In the study, overweight and obese adults were randomized to one of three dietary interventions: 1. advice to replace more than 200 calories a day of calorific beverages (softs drinks/soda) with water 2. advice to replace more than 200 calories […]
Diabetes/Metabolic Syndrome
In one of my blog posts last week I reported on a study which suggested that obesity is a potential cause of vitamin D deficiency, but that vitamin D deficiency is unlikely to have a big role in driving obesity. However, even if this conclusion is utterly correct, it does not mean that boosting vitamin […]
Brain and Behaviour
I read a review paper recently about the assessment of dehydration [1]. The authors conclude that we don’t have very good standardised tests for dehydration, but a reasonable test is to measure heart rate when sitting, and then again immediately on standing. During dehydration the blood volume tends to be lower and blood pressure too. […]
Cholesterol and Statins
We’re often told that statin (cholesterol-reducing) drugs are effective for preventing heart disease and stroke (cardiovascular disease). Whether you buy into this statement or not depends, to a degree, on how you look at the data. It is true that statins reduce the risk of heart attack by about a third. However, this ‘relative risk’ […]
Cholesterol and Statins
So-called ‘omega-3’ fats found in oily fish (like salmon, trout, mackerel and herring) have a reputation for being healthy, including an ability to ward off cardiovascular diseases such as heart disease and stroke. I was interested to read a recent study which points out that while earlier studies found that supplementing individuals with omega-3 fats […]
Specific conditions
Previous research has found a link between lower levels of vitamin D and higher body weight, causing some to speculate that vitamin D deficiency may be a factor in obesity. The problem with this sort of evidence is that while it can show a link between vitamin D deficiency and, say, obesity, we can’t tell […]
