How Much Protein Is in Yellow Onion?

Yellow Onion is listed with 38 kcal, 0.8 g protein, 8.6 g carbs, and 0.1 g fat per 100g when available. These numbers are best treated as estimates because serving size, brand, cooking method, toppings, sauces, and restaurant preparation can all change the final nutrition profile. For protein, look at both the per-100g estimate and the realistic portion size. Foods with more protein may feel more filling for some people, but the overall meal still matters, including vegetables, grains, sauces, and drinks. If Yellow Onion is low in protein, pairing it with a lean protein or higher-protein side can generally make the meal more balanced. It can also help to compare Yellow Onion with a similar food instead of evaluating it in isolation. For example, two foods with similar calories may differ meaningfully in protein, fiber, sugar, or sodium. EatCheck can help scan meals, estimate calories, and keep the decision focused on context rather than strict rules. Nutrition estimates are for general wellness reference and may vary by serving size and preparation method.
