21 Quick and Nutritious Gluten-Free Snacks
If you have celiac disease or gluten intolerance, avoiding gluten is imperative (1).
However, you may struggle to find good snack options.
Though many convenient gluten-free snacks are available in stores, some may be unnecessarily high in calories or added sugars.
However, you don't have to rely on packaged foods for your next snack. It's also simple to make your own.
People with celiac disease should choose snacks rich in fiber, vitamins, and minerals, as dietary restrictions and gluten-related intestinal damage may increase your risk of nutrient deficiencies (2, 3).
Here are 21 quick and nutritious gluten-free snacks.
1. Popcorn with Fruit, Chocolate and Peanuts
For a snack, lightly drizzle air-popped popcorn with melted dark chocolate and toss in fiber-rich dried fruit, such as dried cranberries or cherries. Add peanuts for a good source of healthy fat and plant-based protein (5).
Chocolate and peanuts are naturally gluten-free. However, some may have additives, so be sure to choose products that are certified gluten-free.
2. Turkey-Wrapped Cheese Sticks
Notably, intolerance to lactose — the natural sugar in dairy products — is common in people with celiac disease, but this often improves as your intestine heals on a gluten-free diet (1).
3. Instant Oatmeal with Apple, Walnuts and Cinnamon
Oats are naturally gluten-free but may be contaminated with wheat and other grains during growing, harvest, transportation, and manufacturing. Therefore, you should only buy certified gluten-free oats (1, 8).
For a warm, filling snack, combine plain, instant oatmeal with apples, walnuts, and cinnamon.
4. Cucumber-Hummus Sandwiches
Hummus is a nutritious, protein-rich dip made from ground chickpeas and sesame seeds. Premade gluten-free hummus is sold in supermarkets.
To make mini sandwiches, spread hummus on thick, round slices of cucumber. If you desire, add another slice on top of the hummus.
5. Grass-Fed Beef Jerky
The protein in beef jerky makes it a filling snack. High-quality beef jerky, including gluten-free and grass-fed options, has become more widely available. Notably, grass-fed beef is higher in nutrients like anti-inflammatory omega-3 fats and antioxidants (5, 6, 9).
6. Fruit and Nut Tortilla Roll-Up
Warm the tortilla briefly in the oven, then spread one side with a thin layer of chunky, unsweetened almond butter. Top with fresh berries or half of a diced apple and roll the tortilla tightly.
7. Toast with Beans and Olive Oil
To make a satisfying, protein-rich snack, heat canned navy beans and spread them over toast. Drizzle with extra virgin olive oil and sprinkle with salt and pepper. The toast can also be topped with fresh herbs.
To avoid gluten contamination from toasters, it's a good idea to invest in a new one and only use it for gluten-free foods. When you're away from home, reusable toaster bags can prevent contact with crumbs (1).
8. Yogurt Parfait with Granola
To make this snack, alternate layers of plain Greek yogurt with berries or other fruit, then top with gluten-free granola and nuts or seeds.
Many yogurts contain live and active bacterial cultures that help break down lactose. Thus, you may tolerate these yogurts even if you don't digest milk well (9).
9. Bite-Size Zucchini Pizzas
Gluten-free pizza can be hard to find, but you can make your own with vegetables in place of crust.
Cut zucchini into thick, round slices and brush each side with olive oil. Put the slices on a lined baking sheet in the oven and broil each side for about two minutes, or until they start to brown.
Next, spread pasta sauce on each slice and top with shredded mozzarella or Parmesan cheese. Broil for one minute to melt the cheese.
10. Sweet and Crunchy Stuffed Dates
For a simple snack, fill pitted dates with unsweetened, crunchy peanut butter or a mix of chopped walnuts and unsweetened coconut flakes.
Three dates (72 grams) have 5 grams of fiber, which is 18% of the RDI. People on gluten-free diets are sometimes deficient in fiber and may experience constipation, so these dates may aid your digestive system (5, 16).
11. Mango with Lime Juice and Chili Powder
Chili powder may either be a blend of spices or simply ground chili peppers. To avoid contamination, make sure yours is labeled gluten-free.
12. Tomato-Basil Mozzarella Skewers
Skewered foods make festive appetizers for gatherings. Plus, they're easy to make and enjoyable whether or not you're gluten-free.
For a twist, try serving them with a dressing of extra virgin olive oil and balsamic vinegar.
13. Black Bean Salad with Avocado
For an easy, filling snack, toss half of a cubed avocado with 1/4 cup (43 grams) of black beans. Add chopped onion, fresh cilantro, lime juice, salt, and pepper.
14. Do-It-Yourself Trail Mix
Nutritious trail mix ingredients include nuts, seeds, and unsweetened, dried fruit, such as goji berries and apricots.
It's best to buy these foods in packages rather than bulk bins due to the risk of gluten contamination from containers and scoops.
15. Vegetable Soup
A serving of gluten-free canned soup makes for a great snack. You can also freeze homemade soup in small glass containers for eating later.
Always check that canned soup is certified gluten-free. Besides obvious glutenous ingredients like noodles and barley, some soup is thickened with wheat flour.
16. Tuna Lettuce Cups
Avoid canned tuna with gluten-containing ingredients, such as broth made with wheat protein.
17. Rice Cakes with Peanut Butter and Banana
Rice cakes are commonly made with whole-grain brown rice. Some also contain other nutritious gluten-free whole grains, such as quinoa or sorghum.
Thin rice cakes are about half the thickness of regular ones and work well as sandwiches. Top them with unsweetened peanut butter, banana, and cinnamon.
18. Sweet Potato Chips with Tzatziki Sauce
For extra flavor, pair the chips with tzatziki sauce, which is a yogurt and cucumber dip. You can buy it premade or make your own.
You can also make your own chips. Toss thin slices of sweet potato with olive oil and sea salt, then spread on a pan and bake at 400℉ (204℃) for about 25 minutes or until the edges brown. Flip the chips once during cooking.
19. Honeydew with Raspberries
For a refreshing snack, toss cubed honeydew melon with raspberries, then sprinkle with fresh mint.
Honeydew and raspberries are naturally gluten-free and packed with fiber, minerals, and vitamins, including vitamin C.
20. Egg-Salad-Stuffed Mini Bell Peppers
Miniature bell peppers are perfectly sized for snacking. Cut the peppers in half and remove the seeds before adding egg salad.
To make the salad, chop a hard-boiled egg and mix it with diced green onion and plain Greek yogurt or mayonnaise. Add salt and pepper to taste.
Eggs are a good source of vitamin B12, which up to 41% of people newly diagnosed with celiac disease are deficient in. This vitamin is essential for energy production, nerve function, and DNA synthesis (3, 5, 21).
21. Pear Drizzled with Dark Chocolate
For a sweet snack, melt gluten-free dark chocolate and drizzle it over a sliced pear, then top with crushed walnuts for a boost of protein and healthy fat. Pear slices are also tasty dipped in unsweetened almond butter.
The Bottom Line
Gluten-free snacks don't have to be difficult to make. Plenty of tasty, unique snack combinations can be enjoyed on a gluten-free diet.
To avoid nutritional deficiencies, choose whole foods packed with fiber, vitamins, and minerals.
If you're craving healthy, homemade snacks, try some of these ideas today.

From the mythical minotaur to the mule, creatures created from merging two or more distinct organisms – hybrids – have played defining roles in human history and culture. However, not all hybrids are as fantastic as the minotaur or as dependable as the mule; in fact, some of them cause human diseases.
When Looking Through a Microscope Isn’t Close Enough.<p>For the last few years, <a href="http://www.rokaslab.org/" target="_blank">our team at Vanderbilt University</a>, <a href="https://www.researchgate.net/lab/Gustavo-Goldman-Lab" target="_blank">Gustavo Goldman's team at São Paulo University in Brazil</a> and many other collaborators around the world have been collecting samples of fungi from patients infected with different species of <em>Aspergillus</em> molds. One of the species we are particularly interested in is <a href="https://doi.org/10.1006/rwgn.2001.0082" target="_blank"><em>Aspergillus nidulans</em>, a relatively common and generally harmless fungus</a>. Clinical laboratories typically identify the species of <em>Aspergillus</em> causing the infection by examining cultures of the fungi under the microscope. The problem with this approach is that very closely related species of <em>Aspergillus</em> tend to look very similar in their broad morphology or physical appearance when viewing them through a microscope.</p><p>Interested in examining the varying abilities of different <em>A. nidulans</em> strains to cause disease, we decided to analyze their total genetic content, or genomes. What we saw came as a total surprise. We had not collected <em>A. nidulans</em> but <em>Aspergillus latus</em>, a close relative of <em>A. nidulans</em> and, as we were to soon find out, <a href="https://doi.org/10.1016/j.cub.2020.04.071" target="_blank">a hybrid species that evolved through the fusion of the genomes</a> of two other <em>Aspergillus</em> species: <em>Aspergillus spinulosporus</em> and an unknown close relative of <em>Aspergillus quadrilineatus</em>. Thus, we realized not only that these patients harbored infections from an entirely different species than we thought they were, but also that this species was the first ever <em>Aspergillus</em> hybrid known to cause human infections.</p>
Several Different Fungal Hybrids Cause Human Disease.<p>Hybrid fungi that can cause infections in humans are well known to occur in several different lineages of single-celled fungi known as yeasts. Notable examples include multiple different species of <a href="https://doi.org/10.1002/yea.3242" target="_blank">yeast hybrids</a> that cause the human diseases <a href="https://rarediseases.info.nih.gov/diseases/6218/cryptococcosis" target="_blank">cryptococcosis</a> and <a href="https://www.cdc.gov/fungal/diseases/candidiasis/index.html" target="_blank">candidiasis</a>. Although pathogenic yeast hybrids are well known, our discovery that the <em>A. latus</em> pathogen is a hybrid is a first for molds that cause disease in humans.</p>
(Left) Candida yeasts live on parts of the human body. Imbalance of microbes on the body can allow these yeasts, some of which are hybrids, to grow and cause infection. (Right) Cryptococcus yeasts, including ones that are hybrids, can cause life-threatening infections in primarily immunocompromised people. Centers for Disease Control and Prevention<p><a href="https://doi.org/10.1371/journal.ppat.1008315" target="_blank">Why certain <em>Aspergillus</em> species are so deadly</a> while others are harmless remains unknown. This may in part be because <a href="https://doi.org/10.1016/j.fbr.2007.02.007" target="_blank">combinations of traits, rather than individual traits</a>, underlie organisms' ability to cause disease. So why then are hybrids frequently associated with human disease? Hybrids inherit genetic material from both parents, which may result in new combinations of traits. This may make them more similar to one parent in some of their characteristics, reflect both parents in others or may differ from both in the rest. It is precisely this mix and match of traits that hybrids have inherited from their parental species that <a href="https://www.nytimes.com/2010/09/14/science/14creatures.html" target="_blank">facilitates their evolutionary success</a>, including their ability to cause disease.</p>
The Evolutionary Origin of an Aspergillus Hybrid.<p>Multiple evolutionary paths can lead to the emergence of hybrids. One path is through mating, just as the horse and donkey mate to create a mule. Another path is through the merging or fusion of genetic material from cells of different species.</p><p>It is this second path that appears to have been taken by our fungus. <em>A. latus</em> appears to have two of almost everything compared to its parental species: twice the genome size, twice the total number of genes and so on. But unlike other hybrids, which are often sterile like the mule, we found that <em>A. latus</em> is capable of reproducing both asexually and sexually.</p><p>But how distinct were the parents of <em>A. latus</em>? By comparing the parts contributed by each parent in the <em>A. latus</em> genome, we estimate that its parents are approximately 93% genetically similar, which is about as related as we humans are with lemurs. In other words, <em>A. latus</em>, an agent of infectious disease, is the fungal equivalent of a human-lemur hybrid.</p>
How A. Latus Differs From its Parents.<p>Elucidating the identity of closely related fungal pathogens and how they differ from each other in infection-relevant characteristics is a key step toward reducing the burden of fungal disease. For example, we found that <em>A. latus</em> was three times more resistant than <em>A. nidulans</em>, the species it was originally identified as using microscopy-based methods, to one of the most common antifungal drugs, <a href="https://www.drugbank.ca/drugs/DB00520" target="_blank">caspofungin</a>. This result provides a clear example of the potential importance of accurate identification of the <em>Aspergillus</em> pathogen causing an infection.</p><p>We also examined how <em>A. latus</em> and <em>A. nidulans</em> interact with cells from our immune system. We found that immune cells were less efficient at combating <em>A. latus</em> compared to <em>A. nidulans</em>, suggesting the hybrid fungus may be trickier for our immune systems to identify and destroy.</p><p>In the midst of the COVID-19 pandemic, our quest to understand <em>Aspergillus</em> pathogens is becoming more urgent. Growing evidence suggests that <a href="https://doi.org/10.1111/myc.13096" target="_blank">a fraction of COVID-19 patients are also infected with <em>Aspergillus</em>.</a> More worrying is that these <a href="https://doi.org/10.3201/eid2607.201603" target="_blank">secondary <em>Aspergillus</em> infections</a> can worsen the clinical outcomes for those infected with the novel coronavirus. That being said, we stress that little is known about <em>Aspergillus</em> infections in COVID-19 patients due to a lack of systematic testing, and none of the infections identified so far appear to have been caused by hybrids.</p><p>So, when it comes to hybrids, some are fantastic (the minotaur), some are helpful (the mule) and some are dangerous (<em>Aspergillus latus</em>). Understanding more about the biology of <em>Aspergillus latus</em> may help in our understanding of how microbial pathogens arise and how to best prevent and combat their infections.</p>

World Environment Day: A Time to Consider the Planet We’ll Return To, and Decide How to Care for It Going Forward
It's a different kind of World Environment Day this year. In prior years, it might have been enough to plant a tree, spend some extra time in the garden, or teach kids the importance of recycling. This year we have heavier tasks at hand. It's been months since we've been able to spend sufficient time outside, and as we lustfully watch the beauty of a new spring through our kitchen's glass windows, we have to decide how we'll interact with the natural world on our release, and how we can prevent, or be equipped to handle, future threats against our wellbeing.
