Let’s talk about them.

Change Your Diet To Follow Your Set of Do’s and Don’t Foods

If you’re preparing for a colonoscopy, your doctor may have given you a list of recommended foods to intake and avoid. Knowing these may help in guiding your food choices in the near future.

Remember to check with your dietician before making drastic changes to your diet without the medical recommendation.

Here is a list of some diet suggestions for approved and disapproved food when detoxifying your colon:

Clear liquidsHigh-salt food
FruitsWheat and Gluten
Cold-water fishAlcohol

We must always make diet changes slowly, and continue to maintain balance with what we intake. It applies to any diet change. If there are any nutritional imbalances that we cannot source readily, we can always supplement the lackings!

Drink More Fluids To Avoid Dehydration

The more liquid we intake, the more we dispel. This process is an essential factor in our built-in systems’ toxic waste management. So, it would make sense that we drink more fluids to further our cleanse.

pouring a liquid

When we are limited to certain foods and restricted from others in a particular diet, it is understandable that we would experience dehydration, nausea, and potentially even vomiting during a cleanse. Replenishing lost nutrients is vital, especially during a period when our guts are sensitive.

It is advised to consume about 6-8 glasses of liquids daily. 

Plain water can often be boring to the palette, especially with a low-sugar and low-sodium diet. However, don’t fret! Here are a bunch of delicious ways to help you attain your daily liquid consumption quota:

Eat high-liquid content fruits and vegetables: 

  • Watermelon
  • Strawberries
  • Pineapple
  • Peaches
  • Cucumber


  • Mint
  • Chamomile 
  • Turmeric 
  • Fenugreek 
  • Ginger with lemon

Fasting Diet

Fasting refers to the abstinence of some food and drink. Depending on what fasting type you choose to undergo, the periods of non-fast to fasting differ. 

Before we recommend the benefits, you must know that unbalanced fasting can negatively impact our health. Seek professional opinions before making health decisions, even temporarily.

With this in mind, you may be wondering what the benefits of fasting are on cleansing your gut. There are several reasons why fasting aids in the cleansing of one’s stomach and intestines. 

A popular theory on intermittent fasting as to why it benefits the guts is an interesting story. It says intermittent eating was what our species was most adapted to before food was constantly available. 

The benefits of fasting are health changes, microbiome changes, weight loss, and an improved metabolic system.

Regular Exercise 

Don’t be surprised. We knew exercise would eventually come up in this discussion. We’re mostly lazy bodies that just want to eat our way into a healthy lifestyle, but know this: a change of 30-40 minutes a day of activity is shown to improve our digestive health.

Understanding how the recent pandemic has affected us socially has also affected us biologically. Studies have shown that people in the UK have decreased in their physical activity since the pandemic hit.

You could be one of them. Incorporating a healthy habit requires patience and diligence.

It doesn’t have to be hard!

doing yoga on the beach

Below are some exercises you could do to aid your intestines directly:

  1. Cycling – A quick ride on the bike helps smoothen the guts’ function.
  2. Walking – Walking stimulates intestinal contractility, which refers to the ability of a muscle to flex and stretch at ease. Which aids in the easy passing of stool and waste.
  3. Yoga – Some yoga poses are proven to aid digestion and help reduce belly fat. 
  4. Standing Forward Bend
  5. “Boat” Pose
  6. “Downward and Upward Dog”
  7. “Bow” Pose

Colon Irrigation 

As the name suggests, it is a natural and medical procedure that involves manual flushing of liquid through and out of your digestive tract. This procedure may be done before a colonoscopy. Medical procedures like this are not the solution to your question: How to clean my digestive system naturally. 

Instead, a natural stomach flush should not include a trip to the operating room. Regardless, you still have to visit a doctor for proper instructions on how to clean a digestive system naturally.

It is only practiced for medical purposes and should never be done without professional assistance. Without a medical reason, avoid colon irrigation.

What to expect when you get your colon irrigated:

  • 60 Liters of warm, sterile, filtered water is pumped through a small, rectal tube. 
  • Some liquid may need to sit before passing
  • There may be concerns related to this procedure, such as dehydration, intestinal perforations or tears, infections, or even a change in electrolyte balance.

As such, there are other ways to flush out the colon. It is just one of the many fast ways we can detox our colon

Saltwater Flush

A saltwater flush is one of the methods some use to stimulate colon movements naturally. Those looking to avoid high-sodium intake should stay clear of this method. 

Done alongside excessive water flushing, this method of purging kickstarts the waste movement out of the body.

It is made using warm water and salt that isn’t iodized. This mixture provides a laxative effect that is a fast and non-invasive method. 

The unofficial recipe for this concoction is simple:

  1. 2 Teaspoons of Himalayan salt 
  2. 4 cups warm water 
  3. Mix until it dissolves
  4. Drink the mixture on an empty stomach

You can expect to feel bowel movements shortly after drinking the saltwater.

Consult with your dietitian before trying anything for the first time.

High-fiber Diet

The role of fiber in the waste disposal process of our body helps bulk up waste for ease of passage. Fiber is the carbohydrate component of our food that we don’t digest. Which eventually ends up in our body’s waste.

We can attain this from most types of fruits and vegetables like grapefruits, okras, popcorn, and other high-fiber foods.

Incorporate Probiotics and Prebiotics

Probiotics are the good bacteria we get from fermented foods such as yogurt and kombucha.

Prebiotics refer to soluble fiber that we use to feed that good bacteria. We get prebiotics from foods such as:

  • Dandelion Greens
  • Garlic
  • Onions
  • Cold Pasta which is a source of the prebiotic: resistant-starch.
  • Unripe Green Bananas

A healthy balance of both in the gut aids for a better functioning digestive system.

Poppy Seeds

These are excellent sources of fiber and are highly beneficial to your digestive system. Poppy seeds are often used as a natural cure for constipation. 

Adding these to your diet can surely supplement your cleanse, but shouldn’t be handled the wrong way. Do not put poppy seeds into hot water to steep into a tea. The hot temperature of the water activates the natural opioid of the seed and that is not desirable.

Drinking Herbal Teas

Different teas have different effects on the digestive tract. Teas such as Senna have a natural laxative effect on the body. See which ones you would like to incorporate in your diet.

Below is a list of other ingredients for tea that aids the gut:

  • Peppermint Tea to relax an upset stomach
  • Marshmallow Root with laxative effects
  • Parsley helps with constipation
  • Licorice Root has a soothing effect

Olive Oil

Did you know olive oil can be used as a natural colon cleanser? Olive oil can be a safe way to get stool moving and helps to relieve constipation.

Add it to your routine by consuming one tablespoon of olive oil on an empty stomach in mornings.


If some ingredients that help clean the stomach are unavailable, don’t hesitate to obtain these in the next best thing: Supplements. 

A supplement has its ingredients packed at a specific serving per pill to satisfy the required daily dosage. If you’re looking to turn to supplements to depend on your colon cleansing, here is a list of ingredients that help make that work:

holding a supplement
  • Slippery Elm Bark Powder 
  • Marshmallow Root Powder
  • Licorice Root Extract
  • L-Glutamine
  • Turkey Tail Mushroom

It would be ideal to choose the best supplements for gut health whose ingredients fit the scope of enzymes, probiotics, and prebiotics, as well as antioxidants, to ensure optimal gut health.

7 Tips to Enhance Colon Health

  1. Regular examination of the colon should be performed. See if anything needs to be dealt with, such as early detection of colon cancer.
  2. Adding apple cider vinegar to our regular diet improves the breakdown of sugars, improves digestion, and provides probiotics for our gut.
  3. Increasing the fiber in our diet to about 25-30 grams a day has resulted in better waste passage throughout systems
  4. Vitamin D is known to benefit colon health maintenance and the prevention of osteoporosis.
  5. Stay adequately hydrated. Insufficient hydration can lead to toxin build-up in the body.
  6. Don’t hold back your bowel movements. When you feel them coming, let them go.
  7. Staying active helps in aiding keeping your colon functioning smoothly.
