Fructose is a form of sugar found naturally in fruits and vegetables. It’s also a component of refined table sugar, or sucrose, which is half glucose and half fructose, and of high fructose corn syrup (HFCS), which has a ratio of 55% fructose to 42% glucose.When it was discovered that fructose, unlike glucose, didn’t raise blood sugar levels or insulin and was significantly sweeter than glucose, it was hailed as a boon to all diabetics who could now satisfy a sweet tooth with impunity.But then a dark side of fructose came to light. Scientists discovered that while the body can handle reasonable amounts of fructose from fruits and vegetables without serum fructose concentrations rising to dangerous levels, it can be overwhelmed by large quantities of fructose, especially refined (man-made) fructose. Unfortunately, our steadily increasing consumption of refined sugar and HFCS seems to have done just that.In the 19th century, average refined sugar consumption was about 7 pounds per year p…

A large proportion of our society (36.9% at last estimate) now suffers from “metabolic syndrome.” Metabolic syndrome, which greatly increases the risk of developing heart disease, diabetes and non-alcoholic fatty liver disease (NAFLD), is defined as having at least three of the five following conditions:abdominal obesity (waist circumference greater than 102 cm in men or 88 cm in women)high blood pressure (systolic blood pressure at least 130 mm Hg or diastolic blood pressure at least 85 mm Hg or taking hypertension medications)high blood sugar(fasting plasma glucose level at least 100 mg/dL or taking diabetes medications)high triglycerides (greater than 150 mg/dL)low levels of high density lipoprotein (HDL), the “good” cholesterol (less than 40 mg/dL in men or less than 50 mg/dL in women)Epidemiological studies link fructose found in table sugar (a combination of fructose and glucose) and high fructose corn syrup with metabolic syndrome, but it’s been hard to prove causality.
