Chick-fil-A sandwiches contain anti-foam chemicals used in caulks, adhesives and polishes
Chick-fil-A's chicken sandwiches have recently come under scrutiny due to the presence of anti-foam chemicals that can cause negative health consequences. The ingredients used in these sandwiches are listed on the company's website, and a closer look reveals concerns about their health effects. One of the potentially harmful ingredients is dimethylpolysiloxane, an anti-foaming agent used in the oil used to fry the chicken. While the FDA considers it safe, studies have linked it to negative effects on the immune system and hormonal balance (1). “Dimethylpolysiloxane is often found in vinegar-smelling silicone caulks, adhesives…

Chick-fil-A's chicken sandwiches have recently come under scrutiny due to the presence of anti-foam chemicals that can cause negative health consequences. The ingredients used in these sandwiches are listed on the company's website, and a closer look reveals concerns about their health effects.
One of the potentially harmful ingredients is dimethylpolysiloxane, an anti-foaming agent used in the oil used to fry the chicken. While the FDA considers it safe, studies have linked it to negative effects on the immune system and hormonal balance (1).
“Dimethylpolysiloxane is commonly used in vinegar-smelling silicone caulks, adhesives and aquarium sealants, a component in silicone grease and other silicone-based lubricants, as well as defoamers, mold release agents, dampening fluids, heat transfer fluids, polishes, cosmetics, hair conditioners and

Another ingredient of concern is monosodium glutamate (MSG), which is added to improve the flavor of the chicken. MSG has been linked to headaches, nausea, and allergic reactions in some individuals, and some studies suggest it may contribute to obesity and other health problems (2, 3).
Potassium sorbate is another ingredient found in Chick-fil-A chicken sandwiches that has been linked to allergic reactions and toxic effects on some organs in animal studies (4). Similarly, sodium aluminum phosphate has been linked to kidney damage and bone loss (5) and DATEM has been linked to breathing problems (6).
In addition to these potentially harmful ingredients, Chick-fil-A's chicken sandwiches also contain multiple instances of sugar, soybean oil and palm oil, as well as citric acid and ascorbic acid (2 FDA-recognized chemical preservatives), palm kernel oil, commercial natural flavor, soy lecithin, monoglycerides and fully refined peanut oil. While some of these ingredients may be safe in small amounts, excessive consumption of these ingredients through fast food products can lead to health problems such as obesity, heart disease and diabetes.
Additionally, the Chicken Deluxe Sandwich at Chick-fil-A contains American cheese, which contains sorbic acid, an additional ingredient banned by Whole Foods that has been linked to allergic reactions and toxic effects on some organs in animal studies (7).
It's important to note that Chick-fil-A's website incorrectly claims that their chicken sandwich is served "on a buttered bun." In reality, the bun contains butter-flavored soy and palm kernel oil, with no real dairy. This ingredient misstatement is concerning as it misleads customers about the nutritional value of their products.
There are healthier alternatives to Chick-fil-A's chicken sandwiches that are easy to make at home. Grilled chicken sandwiches made with whole-wheat buns, fresh vegetables, and lean protein are a nutritious and filling option. Additionally, air frying chicken instead of deep frying can help reduce the absorption of harmful chemicals.
In summary, Chick-fil-A's chicken sandwiches contain several ingredients that can have negative health consequences. These ingredients include antifoam agents, MSG, preservatives, and excessive amounts of sugars and oils. As consumers, it is important to pay attention to what we eat and make informed decisions about our food choices to maintain good health.
