Leaky Gut and Gluten: What the Science Says

Leaky gut is the popular name for increased intestinal permeability: the tight junctions between gut cells loosen and let larger particles through. It is a real, measurable phenomenon, and it shows up in celiac disease, Crohn's, and other conditions. The murky part is the wellness industry's version, which blames it for everything from skin rashes to fatigue on thin evidence.

The science does support one clear link: in celiac disease, gluten triggers zonulin release, which opens those junctions. Removing gluten lets the gut lining heal, and permeability normalizes in most people. That part is well documented, not alternative medicine.

Be skeptical of expensive leaky gut protocols sold online. The proven intervention for celiac-related permeability is the gluten-free diet itself, done strictly. No supplement stack has strong evidence behind it.

If gut symptoms persist months into a strict diet, go back to your gastroenterologist rather than a supplement store. Ongoing damage has causes worth finding. Gentle food supports healing. This chicken noodle soup is a good place to start: gluten-free chicken noodle soup.

Popular Gluten-Free Bread Brands: A Shopper's Guide

Image
The gluten-free bread aisle is much bigger than it used to be, and the bags look alike. This guide covers five brands sold in US stores or online, using what each company says about its own products: who certifies them, what else they leave out, and which lines they make. It does not rank them. Taste is yours to judge. What you can check before you buy is the package. What to check on the package A gluten-free claim. In the US, a food labeled gluten-free must contain less than 20 parts per million of gluten under the FDA rule at 21 CFR 101.91. A certification mark, if you want one. A mark such as GFCO's means a third-party program has certified that product. It counts only when it is printed on the bag in your hand. The ingredient list and the allergen statement. Brands differ on eggs, dairy, nuts, soy and sesame, so read both if anyone at your table has other allergies. Where to store it. Some loaves are sold frozen, some fresh and some shelf-stable. The bag tells yo...

Gluten-Free Pumpkin Bread That Stays Moist for Days

Image
October is pumpkin season, and gluten-free pumpkin bread is one of the few quick breads that can taste better without gluten. Pumpkin puree does the heavy lifting: it keeps the crumb moist in a way that gluten-free flour blends struggle to do on their own. The flour blend matters more than the recipe card suggests. A 1-to-1 gluten-free blend that already contains xanthan gum gives the best structure. Skip the rice-flour-heavy mixes, which dry out by day two. If you bake with your own blend, add a quarter teaspoon of xanthan gum per cup of flour. Use canned pumpkin puree, not pumpkin pie filling. Pie filling comes pre-sweetened and pre-spiced, which throws off the sugar and spice balance. Let the puree come to room temperature before mixing so it blends evenly and you avoid streaks of raw flour. The doneness test is where most people go wrong. A toothpick should come out with moist crumbs, not clean. Clean means the loaf baked past its peak. Pull it when the top springs back lightly and...

Cross-Contamination: How to Keep Your Kitchen Safe

For someone with celiac disease, even a tiny amount of gluten can trigger an immune response that damages the small intestine. Cross-contamination in the kitchen is therefore just as dangerous as knowingly eating gluten. The contamination is invisible with no taste or smell. What Is Cross-Contamination? Cross-contamination occurs whenever gluten from one source transfers to gluten-free food. This can happen through shared utensils, cooking surfaces, cooking water, cutting boards, and even airborne flour particles. Equipment That Must Be Dedicated Colanders and strainers: Pasta water from wheat pasta leaves gluten residue trapped in the holes that washing cannot fully remove. Keep a separate GF colander in a distinctive color. Cutting boards: Wooden and plastic boards develop grooves that harbor gluten protein. Dedicate at least one board exclusively to GF use. Wooden utensils: Porous materials absorb proteins that survive washing. Replace with silicone or stainless steel, or maintain a...
