Possible concerns:
Cellulose is a food additive, not a whole-food ingredient with many chemical names which include Carboxymethyl Cellulose, sodium carboxymethyl cellulose, CMC, modified cellulose, and cellulose gel.
A 2015 study found that cellulose can affect gut bacteria and can trigger inflammatory bowel systems and other changes in the gut. It may act like a detergent to disrupt the mucous layer that lines the gut.
The Food and Drug Administration (FDA) has determined that cellulose is not dangerous or hazardous. It is very rare to have an allergic reaction to it. There is really no nutritional value to cellulose.
Of the additives used in processed foods, cellulose probably has very little risk associated with it, BUT the risk will more likely be from eating the highly processed foods it is found in! How many foods can you find in your kitchen with cellulose?
Be blessed and be a blessing,
