The perfect smoothie can satisfy your sweet tooth without a lot of calories — but with bunch of nutrients. Looking for cool ideas to throw in your blender? There are plenty of options for you to try.

They’ll give your smoothie weight, thickness, and a silky texture. Yes, they’re full of fat, but it’s the “good” fat. The kind that’s linked to good heart health and good cholesterol levels. They’ll also help you feel full longer.

You can’t — ahem — beat them, really. They have lots of fiber and will add sweetness and a beautiful red color to your smoothies. They’re also good for your heart and your brain and are loaded with antioxidants. If red’s not your color, you can use yellow beets instead.

Peanut Butter
In a smoothie? Yeah, lots of people do it. It not only adds flavor, it also changes the texture — especially if you use the “crunchy” kind. It has some fiber, and it’s a great source of protein and potassium.

It’s full of nutrients, like potassium and manganese, and will add body and texture to your smoothie. Any kind will do, but check out young Thai coconuts — they’re the ones used to make the “coconut water” sold as a natural, lower-sugar sports drink.

This king of the green leafy veggies is one of the most nutrient-dense foods you can eat, with only 33 calories per 2.5-ounce serving. And along with fruit or lemon juice, it’s surprisingly good in a smoothie.

It’s high in fiber and omega-3 fatty acids, and can help keep your cholesterol levels in a healthy range. Ground flaxseed makes for a smoother smoothie than whole seeds, and your body can absorb it more easily. But go easy: It’s commonly used to help with constipation, so you can imagine what happens when you eat too much of it.

Chia Seeds
They have lots of antioxidants and fatty acids that are linked to healthy cholesterol levels and good heart health, but you may not be able to get them from these seeds as well as you can from other foods. Either way, they’ll add more texture and a nutty flavor to your smoothie — but don’t use more than a tablespoon or so, or you’ll end up with a glass of jelly instead.

It makes everything a little sweeter. Just don’t overdo it — it’s still mostly sugar. The exact ingredients depend on where the honey’s made, but most have small amounts of amino acids, vitamins, minerals, and enzymes that are good for your digestion.

Agave Syrup
Be careful with this one — it’s really just a kind of sugar. It may sound natural, but it’s highly processed, like high-fructose corn syrup. It’s sweeter than regular sugar, so you may use less.
