Reddit reviews Nutricology Dietary Fiber Celllulose, 250-Grams (8.8 ozs)

Cellulose is a form of sugar found in plant life; if you eat vegetables you are eating large amounts of cellulose. Fiber supplements you buy at the store often are cellulose-based. here is some at Amazon

Notice how the author of this article spends most of his time describing where the cellulose is and only has this to say about the cellulose itself: it's fiber, non-nutritional, and possibly linked to adverse effects on cholesterol. That's all he can say.

He frames it negatively, but people generally associate poor foods as having no fiber, so fast food having some added would be a good thing. Every food has chemical parts of it that aren't a nutrient so saying something isn't a nutrient is meaningless. You can look at an apple and find all sorts of chemicals in it that aren't nutrients either, cellulose being one of them.

That study was done on mice and while mice are a good mammalian model, their digestion is not going to be same as ours especially considering our different diets. Cholesterol (or anything related to metabolism) regulation in the body has been the subject of constant studies for decades now and we're still learning the precise mechanics of it. If one day there is enough evidence against cellulose I would follow that and not use it. Until then, it seems safe since we eat it all the time in many different foods and it's a major natural component of vegetables and fruits which we could assume humans have evolved to handle just fine.

This article is just bandwagon hot air. Yes, please tell me more about the non-digestible wood pulp Mr. Cohen, and use more scare quotes this time.
