You’ve likely heard the terms probiotics and prebiotics , but what do they really mean, and why do they matter more as you age?
Your digestive system is home to trillions of bacteria, many of which support digestion, immune function, and even mental clarity. Keeping those bacteria in balance becomes more important, and more challenging as you get older. The right foods can help you maintain a healthy, well-functioning digestive system.
What Are Probiotics?
Probiotics are live, beneficial bacteria that support a healthy balance in your digestive system . They help crowd out harmful bacteria and support digestion.
Probiotic Health Benefits
Helps prevent or ease constipation.
Reduce inflammation in the gut.
Boost the immune system.
May even improve mood and memory.
Best Probiotic Food Sources
Yogurt with live cultures
Kefir
Miso
Tempeh
Kimchi
Sauerkraut
Kombucha
Tip: Always check labels for phrases like “live and active cultures” to make sure you’re getting real probiotics.
What Are Prebiotics?
Prebiotics are a type of fiber your body can’t digest. Your good gut bacteria love to eat them. They act as “fuel” to help probiotics thrive.
Prebiotic Health Benefits
Helps probiotics multiply and stay active.
Supports better nutrient absorption.
Promotes regular bowel movements.
Improves calcium absorption and bone health.
Best Food Sources
Garlic
Onions
Leeks
Asparagus
Bananas
Oats
Apples

📝 Tip: You likely already eat some prebiotics without realizing it. Just aim to eat them more consistently.
Why You Need Probiotics & Prebiotics
Probiotics and prebiotics work best together, similar to a garden and fertilizer. You plant the good bacteria (probiotics), then feed them (prebiotics) so they grow and flourish.
This combo is sometimes referred to as “synbiotics.”
Easy Prebiotic and Probiotic Meal Pairings
Yogurt + banana
Oats + apples
Stir-fried tempeh + garlic and onions
Miso soup + mushrooms and green onions
Should You Take A Supplement?
Food is the best source for pre and probiotics. But a supplement can help if any of these reasons apply.
You’ve recently taken antibiotics.
You have ongoing digestive issues.
Your diet lacks variety.
What To Look For In A Supplement
Contains multiple strains, such as Lactobacillus and Bifidobacterium.
Contains at least 10 billion CFUs.
A label that ensures shelf stability or refrigeration.
📌 Always consult with a healthcare provider before starting new supplements.

Your digestive system plays a major role in your overall health, especially as you get older. From nutrient absorption to immune defense and even mood regulation, your gut does a lot more than break down food. And with age, its needs change. Fortunately, what you eat can help keep things running smoothly.
In this post, we’ll look at how aging affects your gut—and what foods can help support it.
How Aging Affects Your Digestive System
You might notice that digestion feels a little different in your 50s, 60s, and beyond. That’s because several age-related changes begin to affect how your gut functions:
Slower digestion: Your metabolism slows down, which means food moves more slowly through the digestive tract.
Reduced stomach acid: This can impact the absorption of important nutrients like vitamin B12, iron, and calcium.
Less diverse gut bacteria: The balance of “good” bacteria in your gut can shift, affecting everything from digestion to immunity.
More constipation and bloating: Decreased muscle tone in the digestive tract can lead to discomfort and irregularity.
The good news? Food can help address many of these issues—if you give your gut what it needs.
