People Are Taking More Probiotics, but Still Skimping on Fiber

Key Points:

• A recent study analyzing NHANES data found a significant increase in probiotic supplement use from 2009 to 2023, rising from 0.63% to 5.58% in people under 20 and from 1.8% to 6.96% in adults over 20, while fiber intake remained unchanged.
• Experts highlight a disconnect between growing interest in gut health and actual dietary habits, noting that many people prefer supplements as a quick fix rather than improving their fiber-rich diet, which is essential for supporting beneficial gut bacteria.
• Probiotic supplements can support gut health in specific cases, such as reducing antibiotic-associated diarrhea, but they do not replace the broad benefits of a diverse, fiber-rich diet that includes fruits, vegetables, whole grains, and fermented foods.
• Dietitians recommend focusing on a balanced, plant-forward diet, gradually increasing fiber intake, limiting processed foods and added sugars, and incorporating lifestyle factors like sleep, physical activity, and stress management to support overall gut health.
• While probiotic supplement use is rising, experts advise consulting healthcare providers to determine if supplementation is appropriate, especially for people with serious illnesses or compromised immune systems, and emphasize that supplements are only one part of maintaining gut health.
