Yoplait Greek 100 Blueberry Fat Free Yogurt: 14g Protein, Labelgrade B+ (80/100)

The short answer

Yoplait Greek 100 Protein Blueberry gives you 14.4 g of protein for 101 calories in a single 5.3 oz (150 g) cup — about 9.6 g of protein per 100 g (USDA FDC 2717929). It earns a Labelgrade B+ (80/100). The strengths are real and easy to verify on the panel: 14 g of protein in a 100-calorie cup, 0.083 g of saturated fat, 54.6 mg of sodium, and only 6.5 g of total sugar. Two things keep it honest, though. The “100” is the calorie number, not the protein — and the only way a sweet blueberry yogurt lands at 100 calories is by pairing a little added sugar with two no-calorie sweeteners, sucralose and acesulfame potassium. This is a well-built diet yogurt, not a clean-label or a protein-maxed one.

Why the B+

Read top to bottom, the grade tells a consistent story: the dairy itself scores near-perfect on the things a low-fat yogurt should ace (sodium, saturated fat, sugar), and the two soft spots are both about how the cup is engineered — a protein density the name oversells, and a sweetener strategy that leans on sucralose and ace-K. There’s no hidden flaw here; a B+ is exactly where an honestly-built 100-calorie flavored Greek yogurt should land.

What “100” really buys you

The number on the lid is a calorie ceiling, and Yoplait hits it by attacking calories from two directions. Fat is the first: nonfat milk strips the cup to 0.245 g of total fat, removing roughly 50-70 calories versus a whole-milk yogurt. Sugar is the second, and it’s where the formula gets interesting. Instead of sweetening a blueberry yogurt with the 12-15 g of sugar that taste would normally require, the recipe uses just 2.04 g of added sugar (the “sugar” and “fructose” you see in the fruit blend) and lets sucralose and acesulfame potassium carry the rest of the sweetness for zero calories. That’s the whole trick: a sugar-sweetened blueberry cup this size would land closer to 140-170 calories. Whether that trade is worth it depends entirely on how you feel about artificial sweeteners — there’s no nutritional penalty, but there’s no pretending they aren’t there either.

The protein-density gap, in real terms

The single most misleading thing a shopper can assume about this cup is that “Greek 100 Protein” means it’s protein-dense. It isn’t, and the C grade is the honest signal. At 9.6 g per 100 g, you’re getting a real high-protein serving (14.4 g) only because the cup is a full 150 g — the milk solids are diluted by added water and the blueberry blend. A thick strained plain Greek yogurt does 17-23 g of protein in the same size cup, because nothing has been added back to it. If your goal is grams-per-bite — say you’re hitting a protein target on a tight calorie budget — a plain strained Greek is the denser tool. If your goal is a portion-controlled, pre-sweetened 100-calorie snack that still delivers 14 g, this cup is purpose-built for exactly that.

How it compares

Inside Yoplait’s own Greek 100 line the three flavors are near-twins, and the blueberry cup is actually the quiet pick of the bunch: it posts the most protein (14.4 g vs 14 g) and the least total sugar (6.5 g vs 7 g) on the USDA panels, which is why it earns its own B+ (80), a single point below the strawberry cup’s B+ (81). The more meaningful contrast is the same-flavor showdown with Chobani Less Sugar Wild Blueberry. Chobani gives you noticeably more protein (18 g, and a denser 12 g per 100 g) and skips artificial sweeteners entirely, sweetening only with cane sugar — but you pay 79 more calories and more than double the sugar (13.5 g) for it. That’s the real fork: fewest calories and no real-sugar load if you’re fine with sucralose and ace-K (Yoplait), or more protein and a cleaner sweetener list at a higher calorie and sugar cost (Chobani).

Build it from real fruit

The cleanest way to understand this product is to rebuild it. Start with 150 g of plain nonfat Greek yogurt — 15-16 g of protein, 0 g added sugar, no artificial sweeteners, for roughly the same calories as this cup. Stir in a small handful of fresh or frozen blueberries: about 5 g of natural sugar and ~1 g of fiber that the Yoplait cup, despite listing blueberries, doesn’t deliver (its fiber is 0 g). You end up with more protein, real fruit, a gram of fiber, and a panel with no sucralose, no ace-K, and no modified corn starch. What Yoplait sells over that DIY version is the only thing the DIY version lacks: a sealed, pre-portioned, grab-and-go cup. If convenience is the point, that’s a fair trade; if the ingredient list is the point, the 30-second homemade version wins.

Ingredients

Pasteurized grade A nonfat milk, fruit blend (blueberries, water, sugar, fructose, modified corn starch, pectin, guar gum, citric acid, tricalcium phosphate, malic acid, vitamin A acetate, vitamin D3, sodium citrate). Contains 0.5% or less of: natural flavor, yogurt cultures (L. bulgaricus, S. thermophilus), acesulfame potassium, sucralose.

The honest read on this list: a clean nonfat-milk-and-cultures base, a fruit blend doing double duty as flavor and texture (modified corn starch and the gums build body; tricalcium phosphate firms it and bumps calcium to 153 mg), and the two no-calorie sweeteners at the very end that make the 100-calorie math work.
