We eat food every day, but have you ever thought about all the chemicals and ingredients in what you eat? Take a look at this list of chemicals. You probably haven’t heard of most of them, and they might be hard to pronounce. Yet, you consume all of these every time you eat a blueberry. Surprised? You shouldn’t be. Everything around us is made up of chemicals, from the water you drink to the air you breathe.
Water is a chemical substance, which is why it’s confusing when companies claim their foods are “chemical-free” or when someone says, “If you can’t pronounce an ingredient, don’t eat it.” We can break down any food to look like a confusing list of foreign ingredients. If you compare a list of ingredients from a hard candy to a fresh fruit, which seems more chemical-free?
What about man-made chemicals? Sometimes they can be harmful, but not always. For example, think about a beautiful apple compared to sodium thiopental, which is used in lethal injections. The seeds inside apples contain amygdalin, which has a similar toxicity level to sodium thiopental. However, apples pose very little risk because the seeds contain such a small amount. You would have to eat a lot of seeds for it to be harmful.
When we compare citric acid in lemons to aspartame, an artificial sweetener, we find that neither is toxic at typical consumption levels. The truth is, almost everything can be harmful if you have too much of it. Some substances are dangerous after just a few milligrams, while others require much larger amounts.
We should think about these things in a nuanced way. We can’t simply categorize chemicals as natural or synthetic; natural chemicals aren’t always safe, and man-made chemicals aren’t inherently dangerous.
Have you ever eaten a natural watermelon? Probably not, since in 3000 BC, they were much smaller, less sweet, and had many seeds. Over thousands of years, human-guided evolution has transformed fruits like watermelons and sweet corn into the varieties we enjoy today.
This isn’t a defense of processed foods, nor is it to say one side is better than the other. Foods are complex, and a little perspective can go a long way. You simply can’t live a chemical-free life, despite what some brands may suggest. The concept of “detox” is largely a marketing myth.

Choose a packaged food item from home and list all the ingredients. Research each ingredient to find out what it is and its purpose in the food. Share your findings with the class to discuss which ingredients are natural and which are synthetic.
Pick two foods, one natural and one processed. Create a Venn diagram to compare and contrast the chemicals found in each. Present your diagram to the class and explain why some chemicals are present in both foods.
Form two groups and prepare for a debate on the statement: “Natural foods are always healthier than processed foods.” Use scientific evidence to support your arguments and challenge common misconceptions.
Research the history of a common fruit or vegetable, such as watermelon or corn. Create a timeline showing how it has changed over time due to human cultivation. Share your timeline with the class and discuss the impact of these changes.
Watch a science video about food myths, such as fresh versus frozen food or gluten. Write a short review summarizing the key points and what you learned. Share your review with the class and discuss how it changed your perspective on food.

We all eat on a daily basis, but have you ever really thought about how many chemicals and ingredients go into your food?

This version maintains the original message while removing any informal language and ensuring clarity.
Chemicals – Substances with a distinct molecular composition that are produced by or used in a chemical process. – Scientists study how different chemicals interact in the environment to understand their effects on living organisms.
Food – Any nutritious substance that organisms consume to maintain life and growth. – Plants use sunlight to produce food through the process of photosynthesis.
Natural – Existing in or derived from nature; not made or caused by humankind. – Natural habitats are crucial for the survival of many species.
Man-made – Created or caused by human beings as opposed to occurring naturally. – Man-made structures like dams can impact local ecosystems.
Apples – Edible fruits produced by apple trees, known for their sweet taste and nutritional value. – Apples are a good source of vitamins and are often used in scientific studies on plant growth.
Seeds – The reproductive unit of a plant, capable of developing into another plant. – Seeds need water, oxygen, and the right temperature to germinate and grow into new plants.
Toxic – Containing or being poisonous material especially when capable of causing death or serious debilitation. – Some chemicals can be toxic to wildlife if they enter water sources.
Consumption – The act of consuming, as by use, decay, or destruction. – The consumption of energy by living organisms is a fundamental concept in biology.
Evolution – The process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth. – Evolution explains how species adapt to their environments over time.
Processed – Having been subjected to a series of mechanical or chemical operations to change or preserve it. – Processed foods often contain additives that can affect health.
