YOUR GUT & YOUR GAME

Exploring the Microbiome–Performance Link for Kids, Adults & Seniors

When we think about athletic performance and everyday well-being, we tend to focus on muscles, hydration, sleep, and mental toughness. But an unexpected player is gaining attention among scientists and trainers: your gut microbiome—the trillions of bacteria living in your digestive tract. And whether you’re a young athlete, an active adult, or a senior aiming to stay strong and energized, your gut may be just as important as your muscles or your mindset.

Why Your Microbiome Matters

Your microbiome influences:

• Energy levels

• Digestion and nutrient absorption

• Inflammation and soreness

• Immunity

• Mood and focus

• Recovery after activity

For athletes—and anyone who wants to feel and function better—a healthy gut can improve endurance, reduce GI distress, sharpen focus, and support overall resilience.

FOR EVERYONE: THE FOUNDATION

Performance-Boosting Bacteria

Elite athletes have been found to harbor higher levels of certain bacteria such as Veillonella, which metabolize lactate and turn it into extra energy. Other beneficial microbes lower inflammation, help build a stronger gut lining, and improve blood sugar control.

These advantages aren’t limited to pros. Anyone can build a stronger microbiome through daily habits.

What to Eat to Strengthen Your Microbiome

1. Prebiotic-Rich Foods (the food your good bacteria love):

• Oats

• Peanut butter

• Berries

• Bananas

• Whole grains

• Beans

• Onions & garlic

• Sweet potatoes

2. Fermented Foods (add more good bacteria):

• Yogurt

• Greek yogurt

• Kefir

• Sauerkraut

• Kimchi

• Miso

• Kombucha

3. Anti-Inflammatory Foods:

• Salmon

• Tuna

• Leafy greens

• Nuts & seeds

• Olive oil

Colorful fruits (blueberries, oranges, cherries)

Lifestyle Habits That Protect Your Gut

• Sleep: Aim for 7–9 hours

• Hydration: Keeps digestion and gut lining strong

• Stress control: Deep breathing, light movement, time outdoors

• Limit processed foods: Reduces inflammation

KIDS: BUILDING A HEALTHY GUT EARLY

Children’s microbiomes are still developing, which means their gut health responds quickly to habits—good or bad. And for young athletes, a healthy gut supports growth, immunity, and energy.

Why Gut Health Matters for Kids

• Fewer stomach aches and GI issues

• Better focus in school and sports

• More consistent energy levels

• Stronger immunity during the school year

• Improved nutrient absorption during growth spurts

Kid-Friendly Gut-Boosting Foods

• Yogurt with berries

• Oatmeal with banana

• Whole-grain toast with peanut butter

• Apples, pears, and strawberries

• Carrot sticks with hummus

• Whole-grain crackers

• Easy fermented options like kefir smoothies
  

Tips for Parents & Coaches

• Keep snacks simple before games: banana, granola bar, low-fat yogurt

• Avoid heavy, greasy foods right before activity

• Encourage water over sugary drinks

• Add one fiber-rich fruit or veggie per day

• Allow kids to explore new foods—diversity helps their microbes grow

Red Flags to Watch

• Frequent stomach pain

• Bloating after meals

• Low energy or irritability

Chronic constipation
These may signal an imbalanced gut or dietary gaps.

SENIORS: GUT HEALTH FOR LONGEVITY, ENERGY & MOBILITY

As we age, the composition of our microbiome naturally shifts. Seniors often experience decreased microbial diversity, slower digestion, and greater inflammation. But the right habits can restore balance and dramatically improve quality of life.

Why Gut Health Matters for Seniors

• Better nutrient absorption (critical for protein & vitamins)

• Stronger immune system

• Improved cognitive function through the gut–brain axis

• Reduced inflammation in joints and muscles

• More stable blood sugar and energy levels

• Lower risk of constipation and digestive discomfort

Senior-Friendly Gut-Boosting Foods

• Greek yogurt or kefir (high protein)

• Oatmeal or high-fiber cereals

• Soft fruits (berries, ripe bananas, cooked apples)

• Cooked vegetables (easier on digestion)

• Salmon, trout, chia seeds (omega-3s for inflammation)

• Warm soups with beans or lentils

Lifestyle Recommendations for Seniors

• Stay hydrated—dehydration slows digestion and affects microbiome balance

• Aim for gentle daily movement: walking, stretching, tai chi

• Prioritize sleep routines—poor sleep disrupts gut bacteria

• Add probiotics only if recommended by a clinician

• Avoid excessive NSAIDs (they can disrupt gut lining)

• Increase fiber slowly to avoid bloating

Warning Signs That May Require Medical Input

• Unexplained weight loss

• Severe constipation or diarrhea

• Sudden appetite changes

Chronic bloating
These can indicate gut imbalance or underlying medical issues.

THE BOTTOM LINE: YOUR GUT IS PART OF YOUR TEAM

Whether you’re a kid learning to play the game, an adult pushing for peak performance, or a senior staying active and independent, your microbiome is working behind the scenes to support your body and your brain.

Feed it well. Protect it. Treat it like a teammate.

Because when your gut is healthy—your whole game gets better.
