The Claim
The addition of 0.5 g of alpha-cellulose per kg body weight to a controlled liquid diet has no significant effect on zinc absorption in healthy young men, with absorption rates remaining at 33.8% compared to 34.0% on the basal diet.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Adding 0.5 grams of alpha-cellulose per kilogram of body weight to a liquid diet does not change how much zinc the body absorbs in healthy young men.
See the scientific wording
The addition of 0.5 g of alpha-cellulose per kg body weight to a controlled liquid diet has no significant effect on zinc absorption in healthy young men, as absorption remained at 33.8% compared to 34.0% on the basal diet, indicating that this form of dietary fiber does not impair zinc bioavailability under these conditions.
Adding this type of fiber to the diet doesn’t change how well the body absorbs zinc because it doesn’t bind to zinc or block the cells in the gut that take it in. Zinc stays soluble and moves normally into the bloodstream, just like it does without the fiber.
What the research says
1 studyStudy: A stable isotope study of zinc absorption in young men: effects of phytate and a-cellulose
Adding a small amount of this type of fiber to the diet didn’t change how much zinc the men’s bodies absorbed — it stayed almost exactly the same as when they didn’t have the fiber. So, this fiber doesn’t stop the body from taking in zinc.
