5 Surprising Things You Didn’t Know Weren’t Vegan

Complete avoidance of animal products can sometimes feel well-nigh impossible for even the most conscientious consumer. For those on the vegan-vegetarian-discerning omnivore spectrum, there may still be products in your everyday life you’re unaware contain or whose production involved animal ingredients.

Since anyone can benefit from being more informed about what they’re consuming, in Veganissimo A to Z, Reuben Proctor and Lars Thomsen offer a comprehensive reference guide to identifying and avoiding ingredients of animal origin, including some things not commonly thought of as not vegan.

Here are five of those harder-to-pin-down products:

Catgut, gut strings from sheep, has been used in surgical sutures and as strings for musical instruments and tennis rackets. There are now synthetic alternatives widely available.

String instruments like the violin and cello still use horsehair in their bows, but there is such a thing as a vegan violin bow.

Foods Containing Natural Red Dyes

Starbucks came under fire in 2012 for using carmine, a red dye from crushed female cochineal scale insects, in products like the Strawberries & Cream Frappuccino and the Red Velvet Whoopie Pie. Starbucks has discontinued the practice, but cochineal extract continues to be used as food coloring and as a fabric and cosmetics dye.

Carmine is labeled as Natural Red 4 and E120.

Any vegan worth their vegan salt substitute already has gelatin’s number. The gel-forming protein derived from animal skin and bone, especially cattle and pigs, is used as a binding agent and thickener in candies and cakes as well as meat products, but did you know gelatin can be found in the emulsion layer of photographs, films, and x-rays? Unless you’re seeing a movie in digital projection, your next trip to the theater may not be vegan.

Blood Clot Medication

Batroxobin, an enzyme from snake venom, is commonly used in blood work and for treating blood clot disorders.

Heparin, usually obtained from the intestinal mucous membrane of pigs, is a polysaccharide compound used routinely as a medicinal active agent for preventing and treating blood clots following severe injuries, after surgery or in the case of bedridden patients, either as subcutaneous injections or continual infusions.

Beer and Wine

Isinglass, fish glue derived from the air bladders of sturgeons and now other fishes, is used as a fining agent for wine, beer, and other beverages. Here’s a guide to what’s safe (and not) to drink.


 
PETA’s list of animal-derived ingredients and their alternatives is here to help you avoid animal ingredients in food, cosmetics, and other products. Keep in mind that this list is not all-inclusive. There are thousands of technical and patented names for ingredient variations. Many ingredients known by one name can be of animal, vegetable, or synthetic origin. However, don’t let all this overwhelm you—this list is a resource and is here to help! If you have any questions regarding an ingredient in a product, you can always call the manufacturer.

While we hope this list proves helpful, we also want to emphasize that no one can avoid every single animal ingredient. Being vegan is about helping animals, not maintaining personal purity. Boycotting products that may contain trace amounts of animal products can actually be harmful to animals in the long run. For example, by refusing to eat a veggie burger from a restaurant because the bun may contain traces of milk or eggs, you are discouraging that restaurant from offering vegan options because it is seems too difficult a task. So use our list as a guide, and do your best to avoid animal ingredients.


I think we have to die to be a true vegetarian. Very sad.
 
Suture
Background


A surgical suture is used to close the edges of a wound or incision and to repair damaged tissue. There are many kinds of sutures, with different properties suitable for various uses. Sutures can be divided into two main groups: absorbable and non-absorbable. An absorbable suture decomposes in the body. It degrades as a wound or incision heals. A non-absorbable suture resists the body's attempt to dissolve it. Non-absorbable sutures may be removed by a surgeon after a surface incision has healed.

Sutures are made from both man-made and natural materials. Natural suture materials include silk, linen, and catgut, which is actually the dried and treated intestine of a cow or sheep. Synthetic sutures are made from a variety of textiles such as nylon or polyester, formulated specifically for surgical use. Absorbable synthetic sutures are made from polyglycolic acid or other glycolide polymers. Most of the synthetic suture materials have proprietary names, such as Dexon and Vicryl. The water-resistant material Goretex has been used for surgical sutures, and other sutures are made from thin metal wire.

Today, most sutures are made of synthetic polymer fibers. Silk and, rarely, gut sutures are the only materials still in use from ancient times. In fact, gut sutures have been banned in Europe and Japan owing to concerns regarding bovine spongiform encephalopathy. Silk suture is still used, mainly to secure surgical drains.
