Consume at least 25g of fiber per day for women and 35g for men, and use fiber supplements as a simple solution to bridge the common consumption gap.

Data regarding the fiber deficit are very robust: observational surveys such as the NHANES study confirm that average intake hovers around 15g per day, which is about half of the official nutritional guidelines. Regarding health benefits, a major meta-analysis published in The Lancet by Reynolds et al. strongly supports the link between high fiber consumption and better overall vitality. As for the use of supplements to make up for this shortfall, randomized clinical trials (such as those synthesized by McRorie in 2015) demonstrate that they effectively increase intake and support digestive comfort. However, nutrition research qualifies this shortcut: isolated fiber supplements do not offer the same diversity of prebiotics and synergistic micronutrients as whole foods. Dr. Snyder's claim therefore holds up: using supplements is a minimal and pragmatic fallback solution, even if diversifying one's plate remains the ideal.
