High protein yogurts are not just a Greek phenomenon. it turns out that far to the north of the Mediterranean, skyr has been traditionally made for centuries. Just like Greek yogurt, Icelandic skyr is strained to concentrate the flavor and protein.
Siggi’s is the representative Icelandic yogurt sold in the US. Its sales are just a fraction of the Greek style competitors. We decided to compare Siggi’s to Chobani, using the Blueberry flavor (our favorite).
Both products come in a 5.3 oz cup (150 grams). Siggi’s is 110 calories, lower than Chobani’s 130. The sugar content in Siggi’s is 11 grams, one teaspoon less than Chobani’s – 15 grams. And when it comes to protein, Siggi’s has 14 grams vs Chobani’s 12 grams. Nutrients winner = Siggi’s.
This is the ingredient list for Siggi’s:
Nonfat Yogurt (Cultured Pasteurized Nonfat Milk), Live and Active Cultures, Blueberries, Evaporated Cane Juice, Pectin, Locust Bean Gum, Natural Flavor.
Both are pretty decent, with slight variations. There is more sugar than blueberry in Siggi’s even though the overall sugars count (blueberries have sugar too) is lower than Chobani’s. Both use fancy names for their sugar, but its the same exact ingredient – white table sugar.
Chobani’s listing of cultures before the other ingredients seems like a mistake, after all these are tiny bacteria. We like the fact that Siggi’s does not add any flavoring to its yogurt beyond the berries. The pectin in Siggi’s and locust bean gum in Chobani are added to improve the mouthfeel and consistency of the skim milk yogurt, a function that the fat would have played had it not been removed. Unfortunately, natural flavors are added by Chobani. Ingredients winner = Siggi’s.
Bottom line: Despite Siggi’s slight advantages, both yogurts are a good choice. Both will provide you with protein and probiotics in a relatively low calorie package. Though you won’t go wrong with either option, our recommendation is to buy plain yogurt and add your own fruit.
