Margarine has been the subject of many rumours since its invention in the mid-1800s, including that it is bad for cardiovascular health, has no nutritional value, and is made of ingredients also found in paint. One of the most pervasive rumours is that margarine is almost plastic, or one molecule away from plastic. While it is true that margarine shares many of the same molecules as plastic, this is also true of butter, fatty acids in the human body, and many other substances. A basic understanding of chemistry and molecular compounds reveals that margarine and plastic are far from being similar substances.

What You'll Learn
Margarine and plastic have similar chemical backbone structures
The structure of organic compounds depends on how molecules bond together and when they do so. Even a slight variation in molecular structure can result in a completely different product. For example, ethanol and methanol have similar molecular structures, but one is safe to consume while the other is toxic.
Dietitian Caryn Zinn acknowledges the similarity in chemical structures between margarine and plastic but highlights that the same could be said for butter or any fatty acid in the human body. She emphasizes that many varied substances share similar chemical properties, but this does not imply that they have identical characteristics or effects.
While it is technically true that margarine and plastic share many of the same molecules, it is a misleading simplification. The claim that margarine is "almost plastic" due to a single molecular difference is not supported by a basic understanding of chemistry and molecular compounds.

Margarine is made of molecules, just like everything else
The idea that margarine is similar to plastic is a misinterpretation of facts. While margarine may have a similar chemical structure to plastic, it is not the same. Margarine is a product made from molecules, and the way these molecules bond together determines the final product. Margarine has been the subject of various rumours and misconceptions since its invention in the mid-1800s, including claims that it is bad for cardiovascular health, that it was originally livestock feed, and that it has no nutritional value, none of which are true.
The chemical structure of margarine, including its hydrogenated oils (trans fats), has been studied and compared to butter. While it was once marketed as a healthier alternative, studies have shown that these trans fats can be worse for heart health than the natural fats found in butter. However, this does not mean that margarine is similar to plastic. Margarine typically has around 14 ingredients, and while it may share some ingredients with paint, such as water or oil, the presence of different compounds and their unique molecular bonds make margarine a distinct product from plastic.
It is important to understand that the similarity in molecular structure between margarine and plastic does not imply that margarine is unhealthy or unsafe for consumption. Many organic compounds, including vegetable oils, share similar characteristics with margarine. Additionally, some types of plastic, like PLA, are derived from organic compounds, further highlighting the complexity of molecular structures and their diverse outcomes.
In summary, while margarine and plastic may share certain molecular similarities, the unique molecular bonds and combinations of compounds result in distinct end products. Margarine is a product made from molecules, and its chemical structure, while similar to plastic in some ways, does not make it "almost plastic". The spread of rumours and misinformation about margarine highlights the importance of fact-checking and understanding the chemistry behind such claims.

Margarine has 27 ingredients, some shared with paint
Margarine is a blend of vegetable oils, while plastics are polymers, or chains of repeating molecules, of ethylene molecules. Chemically speaking, margarine and plastic share similar molecules, except for one. However, this does not mean that they are the same. The way molecules bond together determines the end product, and even a slight variation in molecular structure can make a big difference. For instance, the difference of just one molecule makes one type of molecule safe to consume and another type potentially fatal.
The claim that margarine and plastic are similar originated from a viral chain email and Facebook post. The post also asserted that margarine shares 27 ingredients with paint. However, this claim is false. Paint typically contains a solvent, binder, pigments, and additives, while margarine contains only eight ingredients: salt, emulsifiers, lecithin, flavouring, colour agent, water, skim milk, and a plant-based oil.
The myth that margarine is similar to plastic may have stemmed from the fact that fats, such as margarine, exhibit plasticity, meaning they can be spread, manipulated, and shaped. However, this does not indicate that they are made of plastic. Fats are composed of triglycerides, which are formed by the reaction of three individual fatty acids with glycerol to create a single large molecule. These triglycerides have different melting points, resulting in some fatty acids remaining solid longer than others.
While it is true that margarine and plastic share some similar molecules, it is important to understand that this does not make them the same. The molecular structure and bonding of molecules play a significant role in determining the final product, and even a slight variation can lead to distinct outcomes.

Margarine was originally livestock feed
Margarine is a butter substitute made primarily from vegetable oils. It was invented by French chemist Hippolyte Mège-Mouriès in 1869. Mège-Mouriès named the product "oleomargarine", combining the Latin word for "olive oil" with the Greek word for "pearl".
The origins of margarine lie in the discovery of margaric acid by French chemist Michel Eugène Chevreul in 1813. At the time, scientists regarded margaric acid as one of the three fatty acids that form most animal fats. However, in 1853, German structural chemist Wilhelm Heinrich Heintz analysed margaric acid as a combination of stearic acid and palmitic acid.
Following a food shortage, the French government offered a prize to anyone who could create a cheap and effective alternative to butter. Mège-Mouriès rose to the challenge, creating margarine with beef tallow as its primary fat source. The product was patented in New York in 1871, and the patent was later sold to Dutch company Jurgens, which became part of Unilever.
Despite its invention in the mid-1800s, margarine has faced various rumours and misconceptions. One such rumour claimed that margarine was originally livestock feed. This claim, however, is untrue. While it is true that margarine has been used as livestock feed in some cases, this was not its original purpose.
Another widespread misconception about margarine is that it is "almost plastic". This rumour originated from chain emails and was quickly spread through social media. The claim is based on the idea that margarine and plastic share similar chemical structures, differing by only one molecule. While chemically, this is true, it is misleading. Many substances share similar chemical properties, but the difference in molecular structure, as well as the bonding of molecules, results in completely different end products.

Margarine is not plastic, despite what some claim
The idea that margarine is almost plastic is a gross oversimplification of chemistry. It is true that both substances share some of the same molecules; however, this does not mean they are interchangeable or that margarine will behave like plastic. The molecular structure of a substance determines its unique properties, and even a slight variation in structure can lead to significant differences in the final product. For example, ethanol and methanol differ by only one molecule, yet one is safe to consume while the other is toxic.
Additionally, the claim that margarine is one molecule away from plastic implies that plastic is composed of a single molecule repeated over and over. This is not an accurate representation of the complex chemical composition of plastic. Plastic is a polymer, which means it is made up of many smaller molecules called monomers that are chemically bonded together to form long chains. These monomers can vary in structure, which is why there are many different types of plastics, each with unique properties.
Furthermore, margarine is primarily a hydrocarbon, similar to vegetable oil and most organic compounds. It is true that some margarines may contain artificial ingredients or trans fats that can be harmful to health, but this is unrelated to their similarity to plastic. In fact, butter, which is often touted as a natural alternative to margarine, also shares a similar chemical structure to plastic.
In conclusion, while it is true that margarine and plastic share some similar molecules, this does not make margarine "almost plastic." Such claims are misleading and based on a simplistic understanding of chemistry. Margarine is a distinct substance with its own unique properties, and its molecular structure is far more complex than a single molecule.

Frequently asked questions
Yes, margarine does share a similar chemical structure with plastic, but this is also true of butter, fatty acids in the human body, and many other substances. The difference of a single molecule is very important—it's what differentiates ethanol from methanol, one of which is safe to consume and the other of which could be fatal.
The rumour started as a chain email and was spread on social media. It was also shared by a TikTok user called "nobody".
Margarine was once marketed as a healthier alternative to butter, but studies have since shown that the trans fats in margarine can be worse for heart health than the natural fats in butter. However, the rumour that margarine has no nutritional value is false.
