Hello! I'm Elena, your nutrition expert from Castelló. Today we're going to travel to the center of our body to talk about the guardians of our health: prebiotics and probiotics.
This morning, while having a natural yogurt here in Novelda, I was thinking about how amazing it is that we have almost 1 kilo of bacteria living in our intestines. Technically, we're walking ecosystems. If we take care of that gut flora, it will take care of us by acting as a filter against pathogens and improving our digestion. But do you know how to tell the difference between the "germ" and its "food"?
Probiotics: The living guests
Probiotics are live microorganisms that, when consumed in adequate amounts, colonize our intestines and balance the flora.
-
Where to find them: In fermented foods such as plain yogurt, kefir, sauerkraut, miso, or kimchi.
-
Direct benefit: They strengthen the intestine's protective barrier, improve nutrient absorption, and help make digestion lighter and reduce gas.
Prebiotics: The feast for your flora
Prebiotics are not alive; they are ingredients (fibers like inulin or FOS) that we cannot digest. They reach the intestine intact and serve as food for our "good" bacteria to multiply.
-
Where to find them: In everyday foods such as artichokes, onion, garlic, asparagus, leeks, legumes, and bananas.
-
The potato trick: If you cook potatoes or sweet potatoes and let them cool, the starch turns into resistant starch. This starch reaches the intestine unchanged, becoming a luxury prebiotic. A cold potato salad is a gift for your microbiota!
Diet vs. Advertising: Don't be fooled
You've probably seen ads for very expensive fermented milks or fortified products. Here's my technical take:
-
Watch out for sugar: Many "detox" fermented milks contain added sugar. Sugar encourages undesirable bacteria such as Clostridium to grow, canceling out the probiotic effect.
-
Plain yogurt: A simple plain yogurt (unsweetened) has the same beneficial effect and is much more affordable.
-
Real food: You don't need milk fortified with inulin if you already eat onion, bananas, and whole grains. Nature has already done the work for you.
Elena's "Life Tip"
Listen to your microbiota: If you notice that when you start eating more fiber (prebiotics) you get more gas, don't worry; your bacteria are adjusting to the feast. Start slowly and stay well hydrated. A healthy flora prevents allergies and improves diseases like Crohn's or colitis. Eat real food and your bacteria will thank you with excellent health!
Are you one of those who already eat fermented foods every day, or do you still struggle to move beyond classic yogurt? Tell me your tips for taking care of your gut flora!
