A clear liquid diet is often recommended before a colonoscopy or other medical procedures. This diet includes water, tea, coffee (without creamer), clear juices, sports drinks, and broths. Solid foods and dairy products are not allowed. Hard candy is generally permitted as part of a clear liquid diet, but it is important to avoid red, blue, or purple colours as these can leave a residue in the bowel that resembles blood. So, while hard candy may be allowed, it is crucial to choose the right colours and follow medical advice to ensure a safe and accurate procedure.

What You'll Learn
Hard candy is allowed the day before a colonoscopy
A clear liquid diet is typically followed on the day before a colonoscopy. This includes beverages such as tea, coffee (without creamer and only in the morning), clear juices like apple, white grape, and white cranberry, sports drinks (excluding purple, red, or blue varieties), carbonated drinks without red colouring, and flavoured waters. Broths or consommés made from chicken or beef broth are also allowed.
Solid foods are generally not permitted as part of the pre-colonoscopy clear liquid diet. However, some soft foods that melt at room temperature, like Jell-O, are allowed as long as they are not red, blue, or purple. This is because red and purple food colouring can leave a residue in the bowel that resembles blood. Hard candy is typically allowed the day before a colonoscopy as long as it is not red, blue, or purple. This is in line with the guidelines for other foods and beverages, which specify avoiding these colours.
It is important to note that specific instructions may vary, and it is always best to consult with a doctor or healthcare provider for personalised advice. Some people have reported being instructed to follow a liquids-only diet before their procedure, which would exclude hard candy. Additionally, while some people have found that consuming light-coloured gummy bears before a colonoscopy was acceptable, others have been advised against it.
To summarise, hard candy in permitted colours (typically avoiding red, blue, and purple) is generally allowed the day before a colonoscopy as part of a clear liquid diet. However, it is important to follow the specific instructions provided by a healthcare professional, as there may be variations in pre-colonoscopy diets.

It should not be red, blue, purple, or contain dairy
A liquid diet is often recommended for those recovering from gastrointestinal procedures or with problems chewing or swallowing. It helps to reduce stress on the digestive tract and should be followed under medical supervision.
When on a liquid diet, it is important to avoid foods and drinks with red, blue, or purple colouring. This is because these colours can leave a residue in the bowel that looks like blood. This applies to items such as Jell-O, Popsicles, hard candy, drinks, and other items that may contain these colours.
Additionally, dairy products should also be avoided on a liquid diet. This includes milk and other milk products, as well as butter and margarine. Non-dairy creamers are also not allowed. Alternatives to dairy milk, such as lactose-free milk, can be consumed on a full liquid diet, but only in certain circumstances. For instance, babies, toddlers, and children may need adjustments to make the diet safe for them, and they should not be given honey if they are under one year old.
It is important to note that a clear liquid diet does not provide adequate calories and nutrients and should not be followed for more than five days unless supplemented by high-protein gelatin or other low-residue supplements.

It is not suitable for a clear liquid diet beyond five days
A clear liquid diet is typically followed on the day before a colonoscopy. This diet includes coffee without creamer and only in the morning, tea (hot or iced) without creamer, clear fruit juices with no pulp (such as apple, white grape, lemonade, or white cranberry), sports drinks that aren't red, blue, or purple, carbonated beverages that aren't red, and clear broths. Hard candy is also allowed, but it should not be red, blue, or purple. This diet is important because it ensures that there is no residue in the bowel that could be mistaken for blood during the colonoscopy. However, it is not suitable for more than five days as it does not provide adequate calories and nutrients.
A clear liquid diet is already lacking in nutrients and calories, and restricting oneself to clear liquids for more than five days can lead to malnutrition and other health issues. The body needs a variety of nutrients to function properly, including protein, carbohydrates, vitamins, and minerals. While some clear liquids, such as fruit juices and sports drinks, can provide some calories and nutrients, they are not sufficient to meet the body's daily needs.
Additionally, the lack of solid food can lead to digestive issues. Solid foods, especially high-fibre foods, are essential for proper digestion and regular bowel movements. Without solid food, the digestive system can become sluggish, leading to constipation and other gastrointestinal problems.
Furthermore, a clear liquid diet can be challenging to sustain over an extended period. It may not be practical or enjoyable to consume only clear liquids beyond a few days. This can lead to a lack of variety in the diet, which can make it difficult to stick to and increase the risk of nutritional deficiencies.
For these reasons, it is important to supplement the clear liquid diet with other low-residue foods or to resume a normal diet after five days. This might include introducing high-protein gelatin or other supplements to ensure adequate nutrient intake. Solid foods can be gradually reintroduced, but it is best to avoid solid foods with high residue, such as dairy products, solid meats, and high-fibre foods, which can be difficult to digest and may impact the accuracy of certain medical tests.
In summary, while a clear liquid diet may be necessary for specific medical procedures or short-term health reasons, it is not suitable for more than five days. Beyond this point, the lack of adequate calories and nutrients can lead to health issues, and the body requires a more diverse range of foods to function optimally. It is always important to consult with a healthcare professional before starting any restricted diet to ensure it is safe and appropriate for your individual needs.

It is not adequate in calories and nutrients
A clear liquid diet is not recommended for more than five days as it is inadequate in calories and nutrients. It delivers low calories, low levels of carbohydrates, and is also very low in protein, vitamins, and minerals. The average adult in the United States requires between 1,600 and 3,000 calories per day to function normally, and it is difficult to achieve this on a liquid diet.
A full liquid diet, on the other hand, includes foods that are nutritionally dense with higher levels of protein and carbohydrates. It can still be inadequate in fiber and certain vitamins, and it may be challenging to meet your optimal nutritional needs. A full liquid diet is generally prescribed for a few days to help transition back to a normal diet and is rarely used for longer than two weeks.
To meet the goals of a full liquid diet, it is important to focus on eating enough to feel satisfied, which may involve several smaller meals throughout the day. The diet should include a variety of six to seven different foods that are nutritionally dense, and it is recommended to keep a food diary to ensure nutritional needs are being met.
Hard candy is not typically considered part of a liquid diet, as it is a solid food. However, it is important to note that red and purple-colored candies should be avoided, as these colors can leave a residue in the bowel that resembles blood.

It should be supplemented with protein gelatin or low-residue supplements
A clear liquid diet is often used in preparation for surgery and lower endoscopy procedures. It includes liquids that you can see through, like tea, black coffee, strained fruit juices with no pulp (e.g. apple juice, white grape juice, and lemonade), and clear broths. Some flavoured gelatins and ice pops are also considered clear liquids if they do not have red, purple, or blue dye. However, this diet is inadequate in calories and nutrients and should not be followed for more than five days unless supplemented by high-protein gelatin or other low-residue supplements.
High-protein gelatin is a good source of protein and can be supplemented with a clear liquid diet to increase its nutritional value. It is important to note that red-coloured gelatin or drinks should be avoided as they can leave a residue in the bowel that resembles blood.
Low-residue supplements are also recommended to accompany a clear liquid diet. A low-residue diet includes restrictions on certain dairy products (no more than 2 cups a day) and proteins, excluding tougher meats and beans. Lean, tender, and soft meats such as beef, lamb, chicken, fish (no bones), and pork are allowed, as are eggs. Certain breads, cereals, and pastas, including white bread and grits (with less than 0.5 grams of fiber) are also part of a low-residue diet.
It is important to consult with a healthcare professional before starting a clear liquid diet or making any significant dietary changes. They will be able to advise on the appropriate duration and any necessary supplements to ensure adequate nutrition and health.
