How to Replace Greek Yogurt With a Non-Dairy Alternative in Smoothies

For creaminess and added healthy fats and fiber to satiate hunger, avocados are the perfect smoothie ingredient. Just stick to one-quarter of the fruit, as it's pretty high in calories. This grape, spinach, and avocado smoothie is packed with skin-clearing ingredients.

If you're missing the protein in Greek yogurt, white beans add 2.5 grams per 55-calorie quarter-cup serving. And because they're flavorless, you'll have no idea you're sipping them down. This metabolism-boosting smoothie contains cannellini beans, green tea, and broccoli — just replace the Greek yogurt with soy yogurt.

While whey protein powder is a great way to increase the protein in your smoothie, it can cause bloating or gas if you're not used to it. Tofu is another source of protein, but it's easy to digest and blends up super-creamy; it's the perfect smoothie ingredient. This smoothie that tastes like a vanilla milkshake is made with half a cup of soft tofu.
