Foods that have a high amount of calories, but little fiber or nutrients, should be reduced or eliminated. These can include foods reported to be very common in the Standard American Diet such as: cheese, sweetened cereal, chips, fast food, ice cream, processed meats like cold cuts or hot dogs, and high-sodium frozen foods.
Fried Foods
Trans fats (commonly only found in fried foods, fast food and fatty packaged products) slow down stool’s transit time through the intestines and essentially “clog up” digestion.
Alcohol
Because it increases urine production and fluid loss, alcohol is difficult on the digestive system and can make constipation worse. To prevent becoming dehydrated, consume alcohol only in small-to-moderate amounts and drink plenty of water at the same time.
Caffeine
Caffeine has various effects on digestion depending on the person. For some, caffeine can cause increased urine production and sometimes worsen feelings of anxiety and constipation — all symptoms of a caffeine overdose. For other people, it helps improve bowel movements by stimulating muscle contractions. Either way, only plan to drink coffee in moderation. Also, consume enough other hydrating liquids throughout the day to offset dehydration from fluid loss.
Refined Flour
Refined flour by nature does not contain any fiber and, therefore, will not help with constipation.
Pasteurized Dairy Products
Many people are lactose intolerant and can become constipated from the over consumption of dairy products. This can also lead to infant constipation, so look out for signs of an intolerance.
