Smoothies are thick beverages made by blending fruits, vegetables, and other ingredients. They can be a great way to increase your intake of fruits and vegetables, fiber, vitamins, and minerals. Common ingredients include leafy greens like spinach and kale, water, yogurt, and fruits. Smoothies can help improve bone strength, support immunity, lower the risk of chronic diseases, and help maintain healthy cholesterol levels. However, people with high blood sugar levels, those concerned about weight gain, and those on certain medications should be cautious. Smoothies can contain high amounts of natural sugars, calories, and vitamin K, which can interfere with some medications.
