Excess sugar consumption is a primary driver of metabolic syndrome
the verdict
SUPPORTED
the evidence backs this
confidence 86/100
Excessive consumption of sugar, particularly fructose, is widely supported by mechanistic, animal, and epidemiological studies as a major driver of metabolic syndrome and its components, such as insulin resistance and hepatic steatosis.
