Fructose Powers a Vicious Cycle

Researchers have found a hitherto unknown molecular mechanism that is driven by fructose and can lead to cardiac enlargement and heart failure.

High consumption of fructose can lead to uncontrolled growth of cardiomyocytes and heart attack.

In recent decades fructose spread throughout the food market, due to a reputation as being less harmful than glucose. In contrast to glucose, fructose barely increases blood glucose levels and insulin secretion. This avoids frequently recurring insulin spikes after any glucose consumption, which are judged harmful. In addition, fructose is sweeter to the taste.

But there’s a downside: the liver converts fructose very efficiently into fat. People who consume too much high-fructose food can in time become overweight and develop high blood pressure, dyslipidaemia with fatty liver and insulin resistance — symptoms that doctors group together under the name metabolic syndrome
