Sweet Strawberry Jam that we made two days ago, raw with active enzymes and unheated! Strawberries contain heart healthy nutrients such as fiber, Vitamin C, potassium and folate. They are among the top three fresh fruits that provide a healthy antioxidant boost. Strawberries pack 10% of our daily iodine needs. One cup of fresh organic strawberries has approximately 13/mcg of iodine. It is important to have a sufficient amount of iodine in the body, so you don't take on radioactive iodine that may be present in the environment.
