Green Tea May Improve Your Rat’s Memory

Posted on June 2, 2016 by Robert Barrington

Owning a rat with poor memory is not a common problem. Rats age relatively rapidly and so as their memories decline with advancing years they are already on borrowed time and long-term care is not likely to be a problem. … Continue reading →

Plasma Antioxidants Associated with Insulin Sensitivity

Posted on April 21, 2016 by Robert Barrington

Insulin resistance is characterised by an increase in the fasting plasma levels of insulin and glucose, and this is caused by a reduction in the efficiency of the insulin signalling system in the peripheral tissues. The development of insulin resistance … Continue reading →

The Oxidative Stress Theory of Insulin Resistance

Posted on April 6, 2016 by Robert Barrington

Insulin resistance is a state whereby the insulin receptor become insensitive to the effects of insulin. As a result blood glucose levels remain elevated even in the fasted state. The presence of glucose in the blood postprandially, when normally levels … Continue reading →

Nitrosamine in Processed Meat May Cause Insulin Resistance

Posted on April 4, 2016 by Robert Barrington

Insulin resistance is now implicated in the development of a number of Western lifestyle diseases including type 2 diabetes, obesity and cardiovascular disease. In addition, deleterious changes to the brain, that can result in dementia may also be caused by … Continue reading →

Why Do Oxidised Fats and Oils Contribute to Insulin Resistance?

Posted on November 3, 2015 by Robert Barrington

Oxidised oils and fats are damaging to the health because when ingested, they are absorbed and interact with tissues causing the initiation free radical chain reactions. This creates oxidative stress in the cells and tissues of the body and in … Continue reading →

Insulin Resistance And Oxidative Stress

Posted on October 25, 2015 by Robert Barrington

Insulin resistance is a likely driver of weight gain. Insulin resistance is characterised by a deterioration of the strength of the signal elicited by insulin on the cell, and as a result the insulin signal becomes less efficient at stimulating … Continue reading →

Is Oxidative Stress The Main Driver of Insulin Resistance?

Posted on October 18, 2015 by Robert Barrington

Obesity, cardiovascular disease and type 2 diabetes are all aetiologically linked through the metabolic syndrome. The observation that all three diseases are associated with oxidative stress, has lead some to speculate that oxidative stress is the causative factor in metabolic … Continue reading →

Oxidised Oils

Posted on October 3, 2015 by Robert Barrington

As well as trans fats the typical Western diet also contains a group of oils called the oxidised fats. Like all biomolecules, fats can react with a number of substances to produce derivatives that change their chemical and physical properties. … Continue reading →

Pycnogenol: Antioxidant Bark

Posted on August 1, 2015 by Robert Barrington

Antioxidants are protective of disease because they inhibit free radical chain reactions, and this reduces oxidative stress. Oxidative stress is associated with many Western lifestyle diseases including cancer, cardiovascular disease, type 2 diabetes, arthritis and obesity. Oxidative stress may initiate … Continue reading →
