Most gluten-free guides focus on what you CAN'T eat. That's backwards — especially if you're training hard.

Here are 5 underrated gluten-free foods that actually support athletic performance:

1. Buckwheat (despite the name, it's 100% gluten-free) — loaded with magnesium and complete protein. Great as a pre-workout carb source.

2. Teff — tiny grain, massive iron content. Perfect for endurance athletes who are already at higher risk of iron deficiency with celiac.

3. Sweet potatoes — slow-digesting carbs, potassium for cramp prevention, and easy on a sensitive gut. The ultimate post-workout recovery food.

4. Sardines — omega-3s for inflammation (which celiac already amplifies), plus calcium and vitamin D. Most celiac athletes are deficient in both.

5. Hemp seeds — 10g protein per 3 tablespoons, complete amino acid profile, and zero gut irritation. Toss them on anything.

The biggest mistake celiac athletes make is just removing gluten and hoping for the best. Your body needs MORE strategic nutrition, not less.

If you want the full breakdown — meal plans, macros, competition-day protocols — I put together a complete guide for exactly this.
