Last month you met your gut microbiome. This week: the grocery list.
A few weeks back, we talked about the trillions of bacteria living in your gut, your "second brain," and how they influence your mood, immunity, and energy.
The response was great, and a few of you asked the obvious follow-up question:
"Okay… so what do I actually eat?"
Fair. Let's fix that. No $80 supplements required.
The Two Words That Matter: Probiotics vs. Prebiotics
Here's the simplest way to remember it:
Probiotics are the good bacteria themselves. You're adding new residents to the neighborhood.
Prebiotics are the food those bacteria eat. You're stocking the neighborhood fridge.
You need both. Most people focus on the first and completely skip the second, which is like adopting a pet and never buying pet food.
The $25 Gut Health Grocery List (Yes, at Publix)
You don't need a specialty store. On your next regular grocery run, grab:
1. Plain Greek yogurt. Look for "live and active cultures" on the label. Skip the flavored ones; some carry more sugar than a candy bar, and sugar feeds the bacteria you don't want. Add your own fruit instead.
2. Bananas. One of the cheapest prebiotics on the shelf. Slightly green ones are even better because they contain resistant starch, a favorite meal for good gut bacteria.
3. Oats. Real oats, not the sugary instant packets. A warm bowl in the morning is a prebiotic powerhouse hiding in plain sight.
4. Sauerkraut or kimchi. Check the refrigerated section. If it's sitting unrefrigerated on a shelf, the good bacteria didn't survive the trip. A forkful as a side dish is plenty.
5. Garlic and onions. You're probably already buying them. Two of the strongest prebiotics there are, and they make everything taste better. Everybody wins.
What About Probiotic Supplements?
Here's the honest answer: most people eating a decent variety of the foods above don't need one.
The supplement aisle is full of bold promises, and the science on which strains help which people is still young. If you do try one, that's a conversation worth having with your doctor first, especially if you have any digestive conditions or take medications.
Food first. Pills second, if at all.
🧬 Feeling Tired, Foggy, or "Off" No Matter What You Do?
The answer might be in your DNA. Your methylation genes control how your body makes energy, balances mood, detoxes, and uses nutrients. When they're not firing right, you feel it.
SelfDecode's at-home Methylation Test analyzes 23 genes (including MTHFR, COMT, and MTR) and turns your DNA into a personalized plan: the exact vitamins, supplements, and habits your body actually needs. No more guessing in the supplement aisle.

The One Habit That Beats Everything on This List
Variety.
Your gut bacteria thrive on different plant foods. Researchers have found that people who eat 30 or more different plants a week (fruits, veggies, nuts, beans, grains, even coffee and herbs count) have noticeably healthier microbiomes than people who eat the same 5 things on repeat.
Don't overthink it. Just ask yourself at the store: "What's one plant I didn't buy last week?"
The Bottom Line
Your second brain is always listening to what you feed it. This week, feed it well:
Yogurt with real fruit. Oats in the morning. A forkful of kraut. One new plant.
Small deposits, big returns.
As always, this newsletter is for information, not medical advice. If you're dealing with ongoing digestive issues, bloating, or changes in your gut health, that's worth a real conversation with your doctor.
Stay well, South Florida. 🌴
