The Claim
Alpha-cellulose administered at a dose of 0.5 g per kg body weight per day has no significant effect on zinc absorption in young men, with absorption rates remaining at 33.8% compared to 34.0% under a 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.
Taking 0.5 grams of alpha-cellulose per kilogram of body weight each day does not change how much zinc the body absorbs from food in young men.
See the scientific wording
Alpha-cellulose at a dose of 0.5 g per kg body weight per day has no significant effect on zinc absorption in young men, as absorption remained at 33.8% compared to 34.0% in the basal diet, indicating that this form of dietary fiber does not interfere with zinc uptake under these conditions.
Alpha-cellulose passes through the gut without binding to zinc or changing the environment where zinc is absorbed, so zinc can still dissolve and be taken up by the gut lining just like it would without the fiber.
What the research says
1 studyStudy: A stable isotope study of zinc absorption in young men: effects of phytate and alpha-cellulose.
Adding this specific type of fiber (alpha-cellulose) to the diet didn’t make young men absorb less zinc — their zinc absorption stayed almost exactly the same as when they didn’t eat the fiber. So, this fiber doesn’t block zinc like some other compounds do.
