A Complete Guide

Everything you need to know about gluten-free grains.


Eating gluten-free doesn’t mean missing out on grains! Explore delicious options that fit your lifestyle without gluten. Discover a variety of nutritious, gluten-free grains and how to add them to your meal plans.

What Is Gluten, and Do You Need to Avoid It?

Gluten is a protein found in wheat, barley, and rye that acts as a “binder” and helps give bread its signature, chewy texture. For most people, it’s a natural source of essential amino acids, fiber, and B vitamins like folate and niacin—nutrients that support your overall wellness. However, it can cause issues for folks with celiac disease or those with gluten intolerance.

The most popular grains contain gluten, but there are plenty of nutritious grains that are naturally gluten-free, too! From breakfasts to snacks, delicious foods are plentiful. 

In this guide, we'll explore which grains to avoid, which are safe for people with gluten intolerance to nosh on, and how you can enjoy them in a nourishing, plant-based lifestyle.

Which Grains Contain Gluten? (Avoid These!)

If you’re following a gluten-free diet, stay away from all foods and drinks that contain the following. Be cautious as even some unexpected products may contain gluten (they can be quite sneaky!):

  • Wheat & Wheat Varieties (Keep an eye out for these wheat terms: Durum, Einkorn, Emmer, Kamut, Spelt, Farro) Always be sure to check the nutritional list on products as well.

  • Barley

  • Rye

  • Triticale 

  • Oats (unless labeled gluten-free—more on this below!)

So… What’s The Deal With Oats?

While oats are naturally gluten-free, they’re often processed in facilities that also handle wheat, barley, or rye, leading to cross-contamination. Next time you’re at the grocery store, look for oats and oat products that are labeled gluten-free. This means the oats haven’t been cross-contaminated.

Which Grains Are Gluten-Free?

Whether you’re looking for breakfast foods, lunch, or dinner, many delicious options are available for everyone. The good news is that there are plenty of naturally gluten-free grains available, providing a good source of fiber, protein, and key nutrients.

Switching to gluten-free whole grains provides a lot of nutritional benefits, including:3

1. High in Fiber for Digestive Health

Fiber is essential for gut health and digestion. Grains like buckwheat, quinoa, and sorghum are fiber-packed, supporting a healthy digestive system.

2. Packed with Essential Vitamins & Minerals

  • Iron & Calcium - Found in teff, amaranth, and quinoa. iron helps carry oxygen throughout your body, keeping energy levels up. Meanwhile, calcium helps maintain strong bones and muscles.

  • Magnesium - Supports heart health and relaxation, especially in millet and brown rice.

  • B Vitamins - Essential for boosting energy and overall health.

3. Blood Sugar — Friendly & Heart Healthy

Many gluten-free grains digest more slowly, which helps keep your blood sugar levels steady and reduces spikes that can lead to crashes. This makes them a great choice for overall heart health, as well as sustained energy throughout the day. 

4. Excellent Source of Plant-Based Protein

Grains like quinoa, amaranth, and teff provide complete protein, making them ideal for a plant-based diet. Protein is essential for building muscle, repairing tissues, and keeping your immune system strong.

Pro Cooking Tips

Want to level up your gluten-free grains? Toast them before cooking. This enhances their natural flavors, especially in quinoa and amaranth, giving them a rich, delicious flavor. 

Meanwhile, tougher grains like sorghum and millet benefit from a quick soak to soften their texture and improve digestibility. And if you really want to maximize flavor, cook your grains in broth instead of water. This easy swap packs every bite with extra nutrients and a deeper, more satisfying taste!

How to Ensure Your Grains Are Truly Gluten-Free

Even naturally gluten-free grains can be contaminated (like oats). Here’s how you can keep things safe:

  • Buy grains labeled “Certified Gluten-Free”.

  • Store gluten-free grains separately from gluten-containing grains.

  • Use separate cookware for gluten-free meal preparation.

What About Ancient Grains?

Ancient grains are a group of grains and seeds that have remained mostly unchanged for thousands of years. These dietary staples are popular in Asia, Africa, and the Middle East.

Ancient grains tend to be less processed and pack more vitamins, minerals, and fiber than common grains like corn, rice, and modern-day wheat. Some studies even show that eating ancient grains can lead to health benefits like lower heart disease risk, improved blood sugar levels, and better digestion.

Are All Ancient Grains Safe To Eat On a Gluten-Free Diet?

Nope! Folks with celiac disease or gluten sensitivity should steer clear of ancient grains that contain gluten, such as barley, einkorn, emmer, farro, freekeh, kamut, and spelt. But good news—gluten-free ancient grains like amaranth, fonio, millet, sorghum, and teff are safe and packed with nutrients.

Which Ancient Grains Are Gluten-Free and Lectin-Free?

If you're looking for grains that are both gluten-free and lectin-free, three stand out: sorghum, millet, and teff. These grains have been staples in African and Asian cuisines for centuries and provide a nutrient-dense, easily digestible alternative for those avoiding both gluten and lectins.
