Fructose: 5 Research-Backed Side-Effects
Fructose is a natural sugar found in many foods like fruits, but it is also made into high fructose corn syrup, called non-fruit fructose.
Regular consumption of non-fruit fructose, like fruit juices, sweeteners, or sodas, might cause health problems.
Research has shown that excessive intake of non-fruit fructose can lead to metabolic disorders like obesity, dyslipidemia, hypertension, insulin resistance, pro-inflammatory state, and pro-thrombosis.
In this article, we list claims of potential benefits and/or side-effects of fructose that we have found research on. Every claim is listed with all of its sources. We get these claims from our Nutrition Tool.
