Made from Stevia Rebaudiana, a plant indigenous to Paraguay and Brazil, this zero-calorie sugar substitute tastes just like table sugar and won't cause a jump in blood sugar levels. In fact, a study in the journal "Metabolism" showed that Stevia increased insulin production in lab animals -- a potential boon for diabetics. Look for the FDA-approved purified extract of Stevia, Rebiana, on ingredient lists.

The Best No. 2: Agave nectar
Looking for a sugar substitute not concocted in a test tube? This honey-like sweetener is made from the sap found in the core of the agave plant. It's sweeter than table sugar, so you can use less to get the same results, while at the same time boosting your recommended daily allowance of vitamins and minerals: It has trace amounts of calcium, iron, potassium and magnesium. Agave nectar also has a lower glycemic index than table sugar (because of its high fructose count), so it won't cause a spike in blood sugar levels, says Alison Massey, MS, RD, a nutritionist at Mercy Medical Center in Baltimore, Md.

The Best No. 1: Honey
Want to lose those love handles fast? Sweeten your morning cup of coffee with honey. A study in "The Scientific World Journal" found that when subjects were given equal amounts of either honey or sugar, those in the honey group actually saw a reduction in both weight and body fat. What's more, this natural elixir has trace amounts of niacin, riboflavin, thiamin, vitamin B6, free-radical fighting antioxidants, and, in raw form, gut-friendly bacteria. This natural sugar substitute topped the lists of every expert we spoke to for good reason: It's low glycemic index keeps sugar levels in check, and it's up to 50 percent sweeter than the white stuff -- so your sweet tooth will be satisfied with less.
Remember the '70s? Disco. Wooden platform sandals. And, everyone's favorite no-calorie sugar substitute: Sweet N' Low. Finally, we could wash down our cake with a can of Tab and still fit into our favorite bell-bottom jeans. That is, until researchers found out that our new go-to sugar substitute was linked to cancer and made us rethink those promising pink packets.
The scary news didn't stop new sugar swaps from hitting the shelves: NutraSweet, Equal and Splenda all promise us zero calories and the same sweet taste as the white stuff. But nutritionists aren't as keen on these sugar substitutes as we are. Researchers at Purdue University in West Lafayette, Ind. found that lab animals given foods sweetened with an artificial sweetener gained more weight than those who consumed sugar. The reason? Sugar substitutes give a shot of sweet taste with zero calories, which confuses the body. When we taste something sweet without getting the expected calories that come with that flavor, it actually makes us hungrier. So we eat more -- and pack on the pounds.
Even natural sugar substitutes, which contain fructose, can wreak havoc on our health if we overindulge. "Very high doses of fructose may have a negative impact on the liver, and high dietary fructose is associated with metabolic syndrome, obesity, heart disease and type II diabetes," says Robin Foroutan, MS, RD, integrative nutritionist and communications chair for Dietitians in Integrative and Functional Medicine.
But let's face it: Living life without sugar isn't feasible. And with all kinds of sneaky sources of sugar (it's in ketchup, soy milk, tomato sauce and a laundry list of other foods you wouldn't expect) it's easy to overdo it. If you take your coffee with a teaspoon or two of the white stuff, you might want to reach for a sugar substitute every now and then. What's more, most sugar substitutes won't cause a spike in blood sugar levels, so you can sidestep the low energy and brain fog that usually follows a sweet treat.
Enter this list of the best and worst sugar substitutes out there. We asked dieticians to fill us in on the ones that aren't doing anything for our health, and the ones that (in moderation) are actually good for us.
