Precautions To Take While Consuming Cranberry Juice

Here are a few precautions you may take while drinking cranberry juice.

  1. Choose your packaged juice. Read the nutrition label while making a purchase. Cranberry juice cocktail (or cocktail drink) is different from real cranberry juice. Juice that is labeled as “made with 100% real juice” and has added natural sweeteners, such as apple juice while breastfeeding may be preferred.
  1. If you plan to prepare cranberry juice at home, then follow the safety and hygiene guidelines to mitigate bacterial contamination. Also, try to retain as much pulp as possible since it can provide you with dietary fiber.

  1. Mothers with type-2 diabetes should discuss the safe intake limit of cranberry juice with a nutritionist.
  1. Prefer whole fruits to juices. Raw cranberry generally has an extremely tart taste. Thus, use it as an added flavor in soups, salads, and other preparations.
