Red Onion
By Foodbe.ai · June 22, 2026

Red onions are not only a flavorful addition to various dishes but also pack a healthful punch. With around 40 calories per 100 grams, they provide antioxidants that may support the body's defense against inflammation. Their pungent yet sweet flavor profile makes them a versatile ingredient, suitable for both raw and cooked applications, while their prebiotic properties can contribute positively to gut health.

In the kitchen, red onions shine when combined with a variety of colorful ingredients. To maximize their polyphenol content, consider incorporating them into a grain bowl or a vibrant chopped salad alongside dark leafy greens and tomatoes. This approach not only enhances the dish's flavor but also boosts its nutritional density, making your meals more healthful and satisfying.
