Smoothies made with yogurt, fruits, milk, and nuts are a healthy choice. Such healthy smoothies can help in controlling weight and maintaining energy. But adding some spices to the smoothie may not give you the results you expect. Adding yogurt to smoothies is good for health. But it is better to avoid adding flavored yogurts to smoothies. Since they contain high amounts of sugar and other artificial ingredients, it is always better to add plain yogurt to smoothies. It contains high amounts of protein and vitamins. Since dry fruits do not contain water and have a high sugar content, it is not healthy to add them to smoothies for breakfast. It also increases the number of calories in the body.
