What Is A Clear Liquid Diet?
According to the National Library of Medicine (NIH), a clear liquid diet is a dietary plan that “consists solely of liquids/semi-liquids that are fully clear.” It is restricted to liquids that remain transparent at room temperature. The foods can have color but have to be transparent. This 3 to 5 day-long diet plan is prescribed by a doctor for people dealing with digestion problems, gastrointestinal tract issues, ulcers, diverticulitis, and before or after gastrointestinal or colon surgeries. We will discuss how a clear liquid diet works in the next section. Read on.
How The Clear Liquid Diet Works
The clear liquid diet is rich in nutrients and electrolytes without being too harsh on digestion. It is meant for those dealing with GI tract inflammation or digestion problems that warrant a surgery or any other medical procedure. The diet provides hydration and the calories required to sustain a normal life for a short period of 3 to 5 days. But can being on a very low-calorie diet for so long be good for you? Yes! Find out why in the next section.
Why Clear Liquid Diet Is Good For You
The clear liquid diet is good for you as it is very light on your stomach. Diarrhea, vomiting, nausea, IBS/IBD, ulcer, diverticulitis, colonoscopy, or any other surgery involving the digestive system calls for giving complete rest to the stomach and the GI tract. You will be on this diet only for a few days before you gradually introduce semi-solid and solid foods to your routine.
