Yoplait Greek 100 Peach: Nutrition & Labelgrade B+ (80/100)
B+ 80 / 100 — Very low saturated fat, very low sodium, and low added sugar — but the low calorie/low sugar count is engineered with sucralose and acesulfame potassium, not by leaving the yogurt unsweetened. Protein density is solid for a flavored cup but below the strained-Greek leaders.
🛒 Buy on Amazon →The short answer
Yoplait Greek 100 Peach delivers 14 g of protein for 100 calories in a 5.3 oz (150 g) cup, with 7 g of total sugar — of which only about 2 g is added (USDA FDC 2737534). It earns a B+ (80/100): near-perfect on saturated fat and sodium, low on added sugar, but held back because the low-calorie, low-sugar profile is engineered with sucralose and acesulfame potassium, not achieved by leaving the cup lightly sweetened.
That’s the one honest caveat the front-of-pack “100 calories” badge skips. The protein is genuinely good for a flavored cup; the sweetener question is the whole decision.
Why the B+
| Dimension | Grade | Score | Why |
|---|---|---|---|
| Protein density | C | 64 / 100 | 9.3 g per 100 g — good for a flavored cup, but the peach-and-water fruit blend dilutes the nonfat-milk base below plain strained-Greek leaders |
| Ingredient quality | B | 77 / 100 | 20 ingredients; flagged for two artificial sweeteners plus tricalcium phosphate and modified corn starch. No HFCS, and real peaches are present |
| Saturated fat | A+ | 100 / 100 | 0 g — nonfat-milk base |
| Sodium | A+ | 100 / 100 | 55.5 mg per cup (~10 mg per oz) — very low |
| Sugar | A | 92 / 100 | 7 g total, ~2 g added. Legitimately low added sugar — but read it alongside the sweeteners that make it possible |
| Fiber | F | 30 / 100 | 0 g — unavoidable for plain dairy |
The fiber “F” is structural — yogurt has no fiber and the formula doesn’t pretend otherwise. The two real, debatable scores are protein density (a “C” because the fruit blend pulls protein-per-100 g below an unflavored strained cup) and ingredient quality (a “B,” docked for the sucralose/ace-K pairing and the starch-and-phosphate body builders). Sodium, saturated fat, and added sugar are all genuinely excellent.
The catch: “low sugar” is built, not baked in
Read the panel in order and the engineering is obvious. The fruit blend contributes a little fructose and sugar, which is why ~2 g of added sugar still shows up — but the sweetness you actually taste comes from acesulfame potassium and sucralose, parked at the very end of the “0.5% or less” group because high-intensity sweeteners work in milligram doses. Strip those two out and a peach cup this lightly sugared would taste sour.
This is the difference between low-sugar and lightly sweetened, and it’s the entire grading story. A sugar-sweetened flavored Greek cup of the same size typically runs 140–170 calories; Yoplait holds it to 100. If artificial sweeteners are a non-issue for you, that’s a clean trade — 14 g of protein, almost no sugar, ready to eat. If you avoid them, the low added-sugar number is misleading and this is the wrong cup.
The peach quirk: a point behind its own twin
Here’s a detail you’d only catch by lining the flavors up side by side: Peach grades B+ (80), but the Strawberry grades B+ (81) — despite identical protein (14 g), identical calories (100), and the identical sucralose-plus-ace-K sweetener system. The gap is one point, entirely from ingredient quality (77 vs 80).
The cause is small but real. The Peach blend lists tricalcium phosphate and its potassium sorbate preservative inside the main ingredient list, while the Strawberry reformulation uses calcium lactate for its calcium and pushes the sorbate down into the “0.5% or less” group. Same brand, same line, same nutrition story — the Peach just carries a slightly heavier additive footprint on paper. It’s a labeling nuance, not a reason to choose one flavor over the other on health grounds.
How it stacks up against its siblings
| Product | Protein / cup | Calories | Added sugar | Sweeteners | Labelgrade |
|---|---|---|---|---|---|
| Yoplait Greek 100 Peach (this) | 14 g | 100 | ~1.95 g | Sucralose + ace-K | B+ (80) |
| Yoplait Greek 100 Strawberry | 14 g | 100 | ~1.95 g | Sucralose + ace-K | B+ (81) |
| Yoplait Greek 100 Blueberry | 14.4 g | 101 | ~2.04 g | Sucralose + ace-K | B+ (80) |
| Dannon Light + Fit (nonfat) | 12 g | ~80 | 3 g | Sucralose + ace-K | B+ (80) |
The three Yoplait Greek 100 flavors are effectively the same cup wearing different fruit — protein clusters at 14 g, added sugar near 2 g, and the sweetener system is constant across all of them. Against the classic diet-yogurt benchmark, Dannon Light + Fit, the Peach trades ~20 extra calories for 2 more grams of protein (14 g vs 12 g) and a hair less added sugar; both lean on the exact same sucralose/ace-K pairing, so neither escapes the artificial-sweetener question. If that question is a dealbreaker, the fix isn’t another cup in this table — it’s a plain Greek yogurt you sweeten yourself, or a cane-sugar-only brand.
Who it’s for
A portable, ready-to-eat 14 g of protein for 100 calories, with calcium (150 mg, ~12% DV) and live cultures, that you can keep in a desk fridge and eat without prep. The cost is a 20-item label and two artificial sweeteners. Buy it if you want diet-friendly protein and don’t mind sucralose; skip it if you do — and if you’re choosing purely on the numbers, the Strawberry is the same product one grade-point cleaner.

Frequently Asked Questions
How much protein is in Yoplait Greek 100 Peach?
14 g of protein per 5.3 oz (150 g) cup (USDA FDC 2737534). That works out to about 9.3 g per 100 g, or 2.6 g per ounce — solid for a flavored yogurt, though plain strained Greek yogurts like Fage 0% or Chobani Plain run higher (16-18 g per cup).
How does it hit only 100 calories?
Two ways. First, it's fat-free (nonfat milk). Second, instead of sweetening with a full dose of sugar, Yoplait uses a small amount of fructose and sugar in the fruit blend plus two no-calorie artificial sweeteners — sucralose and acesulfame potassium. That keeps added sugar to about 2 g and total calories to 100. A sugar-sweetened flavored yogurt this size would typically run 140-170 calories.
How much added sugar is in Yoplait Greek 100 Peach?
About 1.95 g of added sugar per cup (4% of the FDA's 50 g Daily Value), from the fructose and sugar in the fruit blend. Total sugars are 7 g; the rest is naturally-occurring lactose from the milk. The added sugar genuinely is low — but that's because the bulk of the sweetness comes from sucralose and acesulfame potassium, not because the yogurt is lightly sweetened.
Does Yoplait Greek 100 Peach contain artificial sweeteners?
Yes — both sucralose and acesulfame potassium. They're listed at the end of the ingredient panel (in the '0.5% or less' group), which is normal for high-intensity sweeteners since they're used in tiny amounts. If you're avoiding artificial sweeteners, this is the product to skip; a plain Greek yogurt with your own fruit, or a brand that sweetens only with cane sugar, would be the alternative.
Why does the Peach grade one point lower than the Strawberry?
Same 14 g protein, same 100 calories, same sweeteners — but Peach scores B+ (80) and Strawberry B+ (81). The single difference is ingredient quality (77 vs 80): the Peach blend lists tricalcium phosphate and potassium sorbate inside the main ingredient list, while the Strawberry uses calcium lactate and tucks the preservative into the '0.5% or less' group. It's a one-point distinction, not a meaningful nutrition gap.
Is Yoplait Greek 100 Peach actually Greek yogurt?
It's marketed as Greek-style and has the thicker texture and higher protein you'd expect (14 g per cup vs ~5-6 g in Yoplait Original). Modified corn starch, pectin, and guar gum help build the body. It delivers Greek-yogurt protein at a low calorie count; the trade-off is a longer ingredient list than traditional strained Greek yogurt.
Is Yoplait Greek 100 Peach 'high in protein' under FDA rules?
Yes — 14 g per cup is 28% of the FDA's 50 g Daily Value, above the 20% threshold required for a 'high in protein' claim.
