Oats and peanut butter contain all nine indispensable amino acids, but the pair is not usually “complete” on its own unless the rest of your day fills the gaps.

Oats contain protein, yet they’re mainly a whole-grain carb, so they work best as a protein helper, not your only protein source.

Oats are mostly carbohydrates, but they also bring protein and fiber, so they work as both in a meal.

No, oats aren’t a complete protein on their own, but pairing them with milk, yogurt, or legumes rounds out amino acids.

Oats are mostly carbs (including fiber) and they also contain protein; per serving, carbs outweigh protein.

Oatmeal has moderate protein on its own, giving about 5–6 g per cooked cup, and it turns high-protein when paired with milk, yogurt, or eggs.

Nuts are mostly fat by calories, yet most give 4–6 g of protein per ounce, so they count as both.

Nuts aren’t grains; they’re seeds, and most nutrition guides count them with protein foods while their calories come mostly from fat.

Nuts are mostly fat, with moderate protein and low net carbs, but the balance shifts by nut and serving size.

Yes, nuts can add protein, but most are more fat dense; expect about 3 to 7 g protein per 1 oz (28 g) serving.
