What is a clear liquid diet?

Sometimes when we have problems with our stomach or digestive system, we may be asked by our doctors to stick to a clear liquid diet for a couple of days.

So, what can we have while on a clear liquid diet? Well, that depends a little bit on why you’re following it. For example, if you are preparing for surgery or a colonoscopy, you may have extra restrictions in place.

Generally, though, clear liquid diets involve anything that is a clear liquid at room temperature. Examples of acceptable foods and drinks on a clear liquid diet are:

  • Water
  • chicken, beef or vegetable broth (strained to remove any pieces)
  • Black coffee/tea (no milks or creamers)
  • Herbal/green teas
  • clear soda drinks (e.g. Sprite/7up)
  • Jelly/Jello (US)
  • Clear fruit juices without pulp (e.g. clear apple juice)
  • Clear ice lollies/popsicles
  • drinks made from powdered sachets (e.g. Kool Aid, Bolero, etc.)

It’s a good idea to avoid any clear foods or drinks that have red or purple dyes. These can stain the inside of the bowel, making it look inflamed or can cause alarm if vomiting.

Are there any side effects of a clear liquid diet?

Well, this diet is not intended to be followed long term since it cannot provide all of the nutrients you need. You may notice while on a clear liquid diet that you feel hungry, maybe a little nausea at times and you may feel weak or tired. This is quite normal.

DISCLAIMER: If you are diabetic, please seek advice from your doctor before undertaking a clear liquid diet.
