Whatever the occasion, McDonald’s holds a special place in the memories of many people. But what does it hold for your health? We all heard of the “pink slime” allegations a few years back, when the company had to become more transparent of what went into their burgers and chicken nuggets. But what about the fries? Surely, aside from the oil and salt, there cannot be too much wrong with McDonald’s fries, can there?

List of Ingredients in McDonald’s Fries

According to the U.S. published ingredient list on McDonald’s web site, the French fries have several various additives, like TBHQ, dimethylpolysiloxane, and hydrogenated soybean oil.

To explain these unfamiliar terms, TBHQ, or tertiary butylhydroquione, is an aromatic organic compound mainly used to preserve the shelf life of products. It is found in many edible processed food such as noodles and crackers. It is deemed safe in small quantities by the United States Food and Drug Administration. The compound is also used industrially for biodiesel, varnish, and perfume.

Let’s look at one key ingredient, dimethylpolysiloxane, or PDMS. This silicone compound has recently been linked in social media to McDonald’s fries as it is also what makes up the popular child’s toy, Silly Putty. PDMS can be found in trace amounts of the fries as it is used as an anti-foaming agent in the cooking oil to prevent oil splattering.

You may have noticed hydrogenated soybean oil on the list. Soybeans are good for you, right? Not in this case, according to Dr. Joseph Mercola, an osteopathic physician and member of the American College of Nutrition. He associates this particular type of oil with risks to cancer, obesity, asthma, bone degeneration, and heart disease, just to name a few.

Now that we know what is in our favorite fries, let’s take a close look at the nutritional value of these tasty snacks.
