Summer often brings a change in routines, lighter meals, more travel, and for many, a renewed motivation to feel good in their bodies. It’s also the perfect time to pay attention to something most people overlook that is your gut microbiome.
Composed of trillions of bacteria, fungi, and microbes, your gut microbiome plays a key role in digestion, energy levels, skin clarity, immune function, and even mood.
But with busy schedules, processed foods, and summer indulgences, your gut may need a little extra TLC, and July is the ideal month to start.

What Happens to Your Gut in the Summer?
Warm weather can affect your gut both positively and negatively. On one hand, we’re more active, spend more time outdoors, and tend to crave fresh fruits and veggies, all of which are great for microbial diversity.
On the other hand, summer also brings:
- More sugary beverages and alcohol
- Late-night meals or irregular eating patterns
- Travel-related stress or digestive upset
- Reduced fiber intake from BBQ-heavy meals
All of these factors can impact gut balance, leading to bloating, sluggish digestion, or irregularity.
The Science of a Microbiome Reset
Resetting your microbiome doesn’t mean starting from scratch; instead, it means gently nourishing the good bacteria already living in your gut while reducing what harms them. According to the Canadian Digestive Health Foundation and research published in Nature Reviews Gastroenterology & Hepatology, key areas of support include:
- Microbial diversity (more types of good bacteria = better health outcomes)
- Prebiotic intake (fiber that feeds good bacteria)
- Probiotic intake (introducing new beneficial strains)
- Minimizing inflammatory foods (processed, high-sugar, low-fiber)
This isn’t a quick fix; microbiome health is a long game. But small, consistent steps can lead to meaningful changes.
Key Gut-Supporting Habits to Focus On This Month
1. Increase Fiber-Rich Whole Foods
Fiber is your microbiome’s favorite food. When fermented by gut bacteria, it produces short-chain fatty acids that support digestion, immunity, and gut lining integrity.
Try adding:
- Lentils, chickpeas, and black beans
- Berries, bananas (especially green-tipped), apples
- Broccoli, carrots, kale, artichokes
- Chia, flax, and hemp seeds
Fun fact: According to the Dietary Guidelines for Americans, most adults should aim for 25–34g of fiber daily, but average intake is only around 16g.
2. Include Fermented Foods for Probiotic Support
Fermented foods naturally contain beneficial bacteria that may help repopulate your gut and enhance microbial diversity.
Smart additions:
- Yogurt with live cultures
- Kefir (fermented milk) or plant-based alternatives
- Sauerkraut, kimchi, tempeh, miso
- Kombucha (unsweetened, if possible)
These are best consumed daily in small portions. Pair with a prebiotic-rich meal for optimal effect.
3. Limit Ultra-Processed and Sugary Foods
Processed snacks, added sugars, and emulsifiers can disrupt microbial balance and encourage the growth of inflammatory strains.
Watch out for:
- Hidden sugars in sauces, smoothies, and protein bars
- Artificial sweeteners like aspartame or sucralose
- Frequent consumption of deli meats, chips, or white bread
Instead, opt for nutrient-dense snacks: roasted chickpeas, fruit with nut butter, or air-popped popcorn with olive oil.
4. Hydration + Polyphenols = Gut Glow
Staying hydrated helps move food and waste through your intestines and keeps your gut lining healthy. Polyphenols, found in plant foods, have antioxidant and microbiome-enhancing effects.
Try:
- Green tea or hibiscus iced tea
- Berries, grapes, pomegranate
- Dark chocolate (70%+ cacao)
- Olive oil and flaxseed oil
Bonus: These foods may also support skin health, a win-win for hot girl summer.
Lifestyle Habits That Support Your Gut
Gut health isn’t just about what’s on your plate; it’s also about your stress levels, sleep, and movement.
Studies show:
- Chronic stress may disrupt the gut-brain axis
- Poor sleep can reduce microbial diversity
- Exercise promotes microbial balance and digestive flow
Simple summer tips:
- Take a 20-minute post-dinner walk
- Try journaling or box-breathing for stress
- Keep a consistent sleep-wake routine, even on weekends
What If You're Coming Off Antibiotics or a High-Stress Season?
If you've recently been on antibiotics, dealt with burnout, or eaten more processed foods than usual, a reset can help, but patience is key. A gut reset isn’t a detox or cleanse; it’s about:
- Gradual reintroduction of whole foods and fermented items
- Staying consistent with daily fiber
- Giving your gut time (4–8 weeks) to respond
A good place to start? Add a fermented food and fiber source to one meal per day and build from there.
Want to Look Hot this Summer?
During July, gut health offers the perfect seasonal shift to tune in. With more fresh produce, lighter meals, and time outdoors, you can make small but lasting choices that your microbiome will thank you for.
Start with a fiber-rich salad, sip on green tea, add some sauerkraut to your sandwich, and remember: progress, not perfection. Your gut reset doesn’t need to be drastic, just intentional.
Frequently Asked Questions
Can gut health affect mood and energy?
Yes. The gut produces neurotransmitters like serotonin and dopamine. An imbalanced microbiome has been linked to fatigue and low mood in emerging research.
Do I need probiotic supplements?
Not always. Fermented foods are often enough. But after antibiotics or digestive issues, some people may benefit from targeted strains. Speak with your provider before starting a new supplement.
Is it okay to drink kombucha daily?
Many people enjoy kombucha regularly, but opt for low-sugar options and watch your portion size (4–8 oz). Overconsumption may cause bloating in sensitive individuals.
