8. Agave nectar

This plant-derived sweetener/syrup won’t impact your blood sugar levels like sugar will — which is why it’s often marketed as “healthy” or “diabetes-friendly” — but it does pose other harmful effects to the body.

Agave nectar is low in glucose, but very high in fructose. Consuming too much fructose can contribute to insulin resistance, metabolic syndrome, heart disease and type 2 diabetes, according to Healthline.

Your liver will start converting all that excess fructose into fat and this can potentially increase your “bad” cholesterol levels, your risk of fatty liver disease and belly fat accumulation.
