Healthy Eating
I recently had a query via email recently regarding the benefits, or otherwise, of ‘food combining’, and thought I’d blog about it today. Food combining is a term used to describe the nutritional practice of separating concentrated sources of protein (e.g. meat, fish, egg) and carbohydrate (e.g. bread, potato, rice, pasta) at mealtime. Proponents of […]
Healthy Eating
A lot of people find they can lose excess weight reasonably effectively. However, maintaining that weight loss can be another matter. It’s not uncommon for the pounds that have been shed to slowly return, often with a bit of additional interest too. The reasons for failure in this respect are varied and are perhaps the […]
Cholesterol and Statins
BBC Radio 4 this morning had a brief item about margarine. The item focused on the fact that margarine manufacturers can trumpet the presence of ‘heart-healthy’ omega-3 fats on the label. Professor Jack Winkler, Professor of Nutrition Policy at London Metropolitan University made the claim that such labelling is misleading. It seems that margarine manufacturers […]
Nutrients and Supplements
Earlier this month I blogged about a study which found that supplementing elderly individuals with vitamin D was found to enhance their muscle strength. This has at least some relevance because as people age, they can tend to go out less, and therefore be a particular risk for vitamin D deficiency. Vitamin D deficiency is […]
Diabetes/Metabolic Syndrome
Last month, one of my blogs focused on a paper from the American Heart Association which warned of the hazards of eating sugar on cardiovascular health. It put at least some focus on the sugar fructose, which makes up half of table sugar (sucrose), as well as being found in fruit and vegetables, honey and […]
Nutrients and Supplements
Scanning some on-line newspapers today my eye was caught by reports of a couple of studies concerning vitamin D and cancer. The link between this nutrient and this condition is not new ” there is a huge stack of evidence now which shows as association between higher levels of vitamin D in the body and […]
Diabetes/Metabolic Syndrome
When carbohydrate is eaten, blood sugar (glucose) levels usually rise. The speed and extent to which blood sugar releases into the bloodstream has important implications for health. For example, the greater the level of blood sugar disruption, the more insulin will tend to be secreted by a functioning pancreas in response. High levels of this […]
Exercise and Activity
On Monday this week my blog focused on benefits from exercise seen in obese adolescents and children, even in the absence of weight loss. This week also saw the publication of a study which suggests that exercise may have benefits for the elderly too [1]. In this study, almost 2000 elderly individuals aged 70 were […]
Diabetes/Metabolic Syndrome
The obvious answer to this question is ‘yes’, seeing as many wheat-based foods are very disruptive to blood sugar (they have high glycaemic index), particularly when eaten in quantity (meaning they have high glycaemic load too). As a result, the pancreas will generally need to pump out plenty of insulin. This, in time, can lead […]
Children's Health
Last month one of my blogs focused on the evidence which shows that exercise is, generally speaking, really quite ineffective for the purposes of weight loss. That is not to say that there’s nothing to be said for exercise. It is, for example, linked with a reduced risk of chronic and potentially fatal conditions such […]
