Sugar vs. artificial sweeteners—a sweet showdown that stumps even the most health-conscience. Sweetening your coffee isn’t as straightforward as a spoonful of sugar anymore. Here’s what to consider when making your choice:

Artificial sweeteners have come a long way since Sweet’N Low. There are plenty of natural, calorie-free options to choose from—such as stevia, xylitol and erythritol. Unlike sugar, these alternatives are ideal for your pearly whites because they won’t cause cavities. They’re great for diabetics, too!

Natural sweeteners are essentially sugar alcohols. Many people sensitive these may experience symptoms such as cramping, nausea and headaches. Sugar alcohols also pass through your body mostly undigested. Because of this, your appetite may not be as satisfied as it would with regular sugar.

When it comes to the battle of sugar vs. artificial sweeteners, take a hint from our favorite nanny. Whether you enjoy calorie-free or cane, make “a spoonful of sugar” your moderation mantra.
