Cocoa Improves Insulin Resistance

The oxidative stress theory of insulin resistance suggests that excessive free radical production is a causative agent in the development of insulin resistance. Such free radicals are generated by nutrient overload, possibly through fructose feeding, which increases the de novo … Continue reading

Metabolic Syndrome: The Common Link Between Diabetes and Cardiovascular Disease?

The metabolic syndrome is a cluster of metabolic dysfunctions that centre on the development of insulin resistance. Insulin resistance, is a condition that occurs when the hormone insulin no longer is able to elicit cellular effects efficiently. As a result … Continue reading

The Vascular Benefits of Flavonoids

Observational studies show that flavonoid rich foods, including fruits and vegetables, are protective of cardiovascular disease. Further, clinical studies investigating the effects of isolated flavonoids in humans and animals show that they are biologically active. The protective effects of flavonoids … Continue reading

Folic Acid Deficiency: The Cardiovascular Disease Link

Homocysteine is a product of cellular methionine metabolism. Evidence suggests that high levels of plasma homocysteine are a risk factor for cardiovascular disease. Homocysteine may interfere with endothelial physiology through inhibition of nitric oxide synthesis, inducing endothelial dysfunction possibly via … Continue reading

Dietary Arginine and Nitric Oxide Production

Nitric oxide is a signal molecule that has an extensive role in the regulation of cellular function. In particular, nitric oxide is required for the dilation of arteries and low levels in the endothelial lining of the arteries is thought … Continue reading

Arginine and Athletic Performance

Arginine is a conditionally essential protogenic amino acid. Arginine is of interest to athletes because it is known to cause the release of significant amounts of growth hormone. Doses required for this effect are thought to be around 15 to … Continue reading

Atherosclerosis: Is the Old Paradigm Dying?

The traditional view of atherosclerosis is that it is caused by an accumulation of lipids in the endothelial lining of arteries. These lipids we are told, are derived mainly from dietary cholesterol and transported to the artery walls by low … Continue reading
