Iron supplementation found to improve brain function
Iron is an essential nutrient for the making of haemoglobin – the component in red blood cells that carries oxygen and delivers it to the tissues. If iron is deficient in the body, haemoglobin levels can fall and eventually cause anaemia (pathologically low haemoglobin). Symptoms of this can include mental and physical fatigue and low [...]

The meaningless and misleading nature of food health claims
On Tuesday I was giving a presentation, and part of my advice was for individuals to avoid eating much in the way of processed food, including those emblazoned with health-related claims.

Walking and glucosamine helps people with osteoarthritis
Osteoarthritis is a condition characterised by degeneration of cartilage in joints. I commonly affects joints such as the hips and knees, and when it does, it can make walking (and other movements) difficult and painful.

Higher protein diet plus resistance exercise aids weight and fat loss in type 2 diabetics
Where weight and fat loss is concerned, I favour a relatively low-carbohydrate, high-protein diet on the basis that such diets generally outperform low-fat, carb-rich diets traditionally advocated for weight loss. A lower-carb diet I think may have particular advantages for diabetics because, well, they have difficulty handling carbohydrate as a result of impaired insulin function [...]

Why drink water, and how much is enough?

Water makes up about two-thirds of the body, and therefore has the potential to play a critical role in just about any bodily process one cares to mention. Like what? Well, now the benefits [...]

Cranberry found to be effective for urinary tract infection prevention in girls
Urinary tract infections are common in women, and for some women can be recurrent and require repeated doses of antibiotics or even prophylactic antibiotics. Organisms (usually E. coli) that cause UTIs generally gain access to the bladder via the urethra (the pipe connecting the bladder with the outside). Some of the strategies that may help [...]

My friend’s son reminds me how important blood sugar control is to energy and mood
I was talking to a son of a friend of mine over the weekend. Mark (not his real name) is 18 and has been finding his energy and motivation can flag at times. Some of the time he can be energised and motivated. Other times he feels lethargic and “can’t be bothered with life”. Naturally, [...]

On Wednesday morning I had a nice chat over coffee with Oliver Gillie, a writer and researcher with a particular interest in vitamin D. We spent much of our time talking about the role vitamin D may have in a wide range of conditions including role in a range of conditions including cancer, diabetes, multiple [...]
