Fructose, a natural sugar found in fruits and honey, isn't inherently bad; however, excess consumption, particularly from processed sources like high-fructose corn syrup (HFCS), poses significant health risks.
The Two Sides of Fructose:
Natural Fructose (in fruits, honey): As part of a balanced diet, fructose from natural sources offers nutritional benefits alongside vitamins, minerals, and fiber. Moderate intake is generally considered safe and even healthy.
Processed Fructose (in HFCS, sugary drinks): The problem arises with added fructose, especially in highly processed foods and beverages. Studies show a link between excessive consumption of processed fructose and various health issues.

Moderate Fructose Intake: Benefits and Risks
While excessive fructose is detrimental, moderate consumption from natural sources appears to pose minimal risk. One study suggests that intake between 0 and ~80-90 grams per day is unlikely to cause significant health problems for most people.
