In recent weeks, a series of viral videos circulating on social media platforms like Instagram, Facebook, and TikTok have been warning people to steer clear of packaged, preshredded cheeses. These videos claim that the powdery substance found on shredded cheese, which prevents clumping, is actually “wood shavings,” “bark,” or “sawdust.” The alarming claims have sparked concern among viewers, with many stating that they will no longer purchase shredded cheese. But what do dietitians have to say about these claims?
Registered dietitian Kristina Cooke warns that such videos can instill fear in viewers who are already skeptical about the food system. She emphasizes the importance of obtaining information from scientifically sound and credible sources to avoid misinformation. Experts in the field assert that both preshredded and block cheeses are safe and healthy to consume, debunking the myths propagated by these viral videos.
The powdery substance found on shredded cheese is known as cellulose, an organic structural compound. Cellulose, also referred to as cellulose gum, carboxymethyl cellulose, or microcrystalline cellulose, serves as a food additive to prevent cheese from clumping together. Caroline Susie, a registered dietitian, explains that cellulose is also used as a calorie reducer, anti-caking agent, thickener, and texture enhancer in various food products. Additionally, cellulose helps absorb excess moisture, thereby extending the shelf life of certain items.
Cellulose used in food additives is typically derived from wood pulp or cotton lint, according to the Center for Science in the Public Interest. Cooke clarifies that the edible cellulose used in food is extracted from non-edible portions and is molecularly identical to the cellulose found in plant matter. In fact, cellulose is naturally present in all plant-based foods, contributing to their structural integrity.
The safety of consuming cellulose, whether natural or additive, is supported by the Food and Drug Administration, which recognizes it as generally safe (GRAS). Jen Messer, a registered dietitian, explains that humans lack the enzymes necessary to break down cellulose, allowing it to pass through the digestive system without absorption. Cellulose also functions as dietary fiber, aiding in digestive health, cholesterol and blood sugar regulation, and promoting satiety.
Cellulose can be found in a variety of foods beyond shredded cheese, including bread, ice cream, pancake syrup, condiments, granola bars, yogurt, spices, processed meat, meal replacement shakes, and fiber supplements. It is naturally abundant in fruits, vegetables, grains, beans, lentils, nuts, and seeds. Amy Goodson, a nutritionist, highlights celery as a particularly rich source of cellulose, noting its stringy texture.
When it comes to choosing between block and shredded cheese, experts emphasize that both options offer similar nutritional benefits. Goodson points out that both types of cheese provide essential nutrients such as calcium, protein, vitamin B12, selenium, niacin, riboflavin, and iodine. The decision between block and shredded cheese often boils down to factors like cost, convenience, and taste preferences.
While shredded cheese may contain additives and preservatives that slightly alter its flavor compared to freshly grated cheese, it offers greater convenience and longer shelf life. On the other hand, block cheese may provide a fresher taste and smoother melting properties. Ultimately, the choice between block and shredded cheese depends on individual preferences and needs.
In conclusion, the recent viral videos spreading misinformation about shredded cheese highlight the importance of seeking information from reliable sources. Cellulose, the powdery substance found on shredded cheese, is safe to consume and serves various functions in food products. Both block and shredded cheeses are nutritious options, with differences in taste, convenience, and cost. By understanding the facts about cellulose and shredded cheese, consumers can make informed choices about their dietary preferences.
