This one is easy - YES! Starting your day with a smoothie is a fantastic idea, and breakfast is the perfect time to enjoy one! However, it's all about diversity. Smoothies contain loads of vitamins, and you'll want to make sure you consume different types of veggies, fruits, and berries in your smoothies to make them versatile enough. Also, be mindful of citrus fruits and other ingredients, like nuts, that can be allergic. It is possible to experience an allergic reaction to citrus fruits, such as oranges and lemons, even if you typically do not have any issues with them. This may occur when consuming large quantities of these fruits.
