Types of Fibers You Should Eat After Bariatric Surgery

Bariatric surgery aims to ensure the health and fitness of an individual. A balanced diet is vital for this purpose.

A balanced diet ensures the desired fitness of an individual according to his weight and height for each age group which is calculated as BMI (body mass index). Being either overweight or underweight is a risk factor for many unwanted diseases. Therefore, proper guidance related to dietary requirements is essential for every individual.

What is fiber?

Fibers are non-digestible carbohydrates found in foods. It is categorized on the basis of its solubility in water as Soluble and Insoluble. According to their metabolizing nature by gut bacteria as Fermentable and Non-fermentable, some types may overlap. 

Fibers are not digested foods. They are the source of nutrition for the good bacteria present in our gut. These bacteria are entirely harmless and naturally present in our hearts. They have special enzymes to ferment the fibers and get energy, otherwise serving essential functions in our body like production of short-chain fatty acids like acetate butyrate, propionate, etc., and vitamin K production. 


Sources of fibers

The sources of fibers differ according to the types. 

Foods with soluble fiber include oatmeal, nuts, beans, lentils, apples, and blueberries.

While, foods with insoluble fiber include wheat, whole wheat bread, whole grain couscous, brown rice, legumes, carrots, cucumbers, and tomatoes.

Soluble fibers dissolve in water. They help in decreasing blood glucose and cholesterol levels. Insoluble fibers do not get dissolved in water. They help in facilitating the movement of food within the gastrointestinal tract. They help in preventing and relieving constipation.
