The primary ingredient in a smoothie is typically fruit or a combination of fruits. Common choices include bananas, berries, mangoes, and spinach, depending on personal taste and nutritional goals. Smoothies often include additional ingredients such as yogurt, milk, juice, or plant-based milk to enhance creaminess and flavor. To boost nutritional value, people may add ingredients like protein powder, chia seeds, or nut butter. The consistency is usually blended to a smooth texture, making smoothies a convenient and nutritious option for breakfast or snacks that can be easily customized to individual preferences.
