This recipe is great for high-calorie snacks because it offers a combination of fresh fruits, vegetables, and healthy omega-3 fatty acids from chia seeds. The orange and carrot provide vitamin C and beta-carotene, while the banana is a good source of natural sweetness and fiber. The addition of chia seeds increases the nutritional value of the smoothie by providing additional protein, fiber, and healthy fats. The almond milk or oat barista provides a creamy consistency and additional nutrients.
