However, the fructose in HFCS is part of a man-made blend (as opposed to natural sugars in fruit) and it can have harmful effects as manufactured fructose metabolizes differently in the body.
In a study published in the Journal of Nutrition, researchers reported that consumption of HFCS led to higher levels of trigylcerides – fatty substances in the bloodstream that increase the risk of heart disease.
Fruit juices, whether from concentrate or not, can also be bad for Polycystic Ovarian Syndrome. They are a more concentrated source of sugar and lack the fiber of fresh fruit that blunts increases in blood sugar. Worse, some brands of juice even have added HFCS and more sugars overall than soft drinks!
Tip: Make a habit of reading the ingredient lists on bottles and packaging. Pay attention to controlling your sweet tooth and limit your intake of all added sweeteners – such as HFCS and sucrose (sugar) – to improve your control of blood sugar. Get sweetness naturally by eating moderate amounts of low glycemic index (GI) fruit for healthy fiber as part of your balanced, nutritious PCOS diet.
