Ms. Geek Speaks: Colonoscopy Do it Diet

My husband and I have both had colonoscopy surgeries, but we had different approaches. I started my preparations a full week ahead (seven days). He just did the 24-hour no solid food prep and his day was painful.

My husband’s doctor didn’t mention anything about what to do a week before. My doctor(s) didn’t say anything about preparing seven days before, but I did some research. This is what made the difference for the day you face the Miralax and Gatorade. 


For seven to four days before your procedure, you should avoid:


  • whole grains,
  • popcorn,
  • fatty food
  • tough meat
  • corn, 
  • broccoli
  • cabbage
  • beans
  • peas
  • nuts,
  • seeds,
  • dried fruits or
  • raw fruits/vegetables
  • seaweed
  • glutinous rice, black rice
  • bamboo shoots
  • dragonfruit
  • black fungus
  • sesame
  • animal blood, animal liver, 
  • red dates

Also on the list is glutinous rice and seaweed which means no sushi. This list was for an East Asian dietary restrictions. 



  • Digestive tea 
  • Milk, Cream, Buttermilk
  • Hot chocolate
  • Cheese, including Cottage Cheese
  • Yogurt,  Sour Cream
  • White flour breads including muffins and bagels
  • Plain Crackers
  • Low-fiber cereal (puffed rice, cream of wheat or corn flakes)
  • Pasta
  • Smoothies
  • Fruit juice without pulp
  • Melon (cantaloupe and honeydew)
  • Peeled Apricots and peaches
  • Canned Fruit without seeds or Skin
  • Eggs
  • White Rice
  • Salmon 
  • Fish, Seafood
  • Chicken , Turkey
  • Lamb
  • Pork, Veal
  • Tofu
  • Steamed vegetables without skin
  • Potatoes without skin
  • Cucumbers without seeds or peel
  • Cream nut butter

I also added flour tortillas and cheese without any nuts, berries, spices or red pieces in it.

Kaiser Permanente has a great list.

Favorite Drinks for Colonoscopy Prep

  • Organic low-sodium broth
  • Really good JELL-O (not red, orange or purple)
  • Martinelli’s Gold Medal apple juice
  • White grape juice
  • Flavored sparkling water
  • 7-UP or Sprite
  • Good coffee (without creamer)
  • Gummy bears – pull out the red and purple ones, and suck the light ones for a little treat

WebMD: How to Prepare for a Colonoscopy

I was dubious about the instructions, the doctor sent because it gave the same preparation for people of any size. I am the size of a 12-year-old (under five feet high and under 100 lbs.) , so I did half of what was required which was:

  • 2 tablets of 5 MG Dulcolax at 12 p.m. with clear fluids
  • 8.15 oz of Miralax into a 32-oz bottle of Smartwater at 4 p.m. but in a split dose. Half at 4 p.m. and the rest at 6 p.m. 

Check the numbers to make sure you’re getting the right amount and don’t go by bottle/pill or price.  I made a mistake because originally, I was given kits, but this time, I was not sent a kit. 

Here is the sheet I was given:


  • DO EAT

    • White bread, pasta, and rice
    • Well-cooked vegetables without skin
    • Fruit without skin or seeds
    • Lean meat, chicken, or fish
    • Eggs
