Toxic food environment

Toxic food environment is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Toxic food environment rather than just read about it. In short: A food environment is the "physical presence of food that affects a person's diet, a person's proximity to food store locations, the distribution of food stores, food service, and any physical entity by which food may be obtained, or a connected system that allows access to food". The term toxic food environment was coined by Kelly D.

Key takeaways

  • Toxic food environment belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Toxic food environment to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Toxic food environment from memory before moving on to harder problems.

Reference excerpt

A food environment is the "physical presence of food that affects a person's diet, a person's proximity to food store locations, the distribution of food stores, food service, and any physical entity by which food may be obtained, or a connected system that allows access to food". The term toxic food environment was coined by Kelly D. Brownell in his book, Food Fight: The Inside Story of the Food Industry which describes American culture at the end of the 20th century as one that fosters and promotes obesity and unprecedented food consumption. In the United States, the food environment the citizens are encompassed in makes it far too hard to choose healthy foods, and all too easy to choose unhealthy foods. Some call this food environment "'toxic' because of the way it corrodes healthy lifestyles and promotes obesity". Brownell was a Yale professor and director of the Rudd Center for Food Policy and Obesity at Yale. He is now director of the World Food Policy Center of the Sanford School of Public Policy at Duke University. He uses the term "toxic" to describe unparalleled exposure to high-calorie, high-fat, heavily marketed, inexpensive, and readily accessible foods. The toxic environment is the result of ubiquity of unhealthy, processed foods, an increasingly sedentary lifestyle in which individuals spend more time watching TV and using computers than they spend exercising, the explosion of fast food restaurants, the enormous growth of portion sizes, the power of food advertising and marketing, and the junk food industry's takeover of schools by selling unhealthy items in vending machines, cafeterias, and through school fundraisers. A main contributor to the notion of a toxic food environment is the marketing of it. Finding an advertisement that promotes "toxic" is not a difficult task. The Federal Trade Commission found, in 2008, that the food industry spent almost $10 billion per year on marketing food and beverages, including $1.6 billion toward children. Marketing for "toxic" food has infused the consumption of unhealthy, processed food into US culture. Brownell and many of his colleagues attribute the nation's obesity epidemic to the toxic environment. In 1995, the Institute of Medicine noted that the human gene pool has not undergone any real change over the past several decades when obesity has been on the rise. Therefore, the root of the obesity crisis must lie in the environment—the social and cultural forces that promote an over-abundance of food and eating, and a deficit of physical activity.

Worked examples

Example 1 — a first encounter with Toxic food environment

Start with the simplest possible case. Write down what Toxic food environment claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Toxic food environment before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Toxic food environment ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Toxic food environment

In research
Toxic food environment appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Toxic food environment in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Toxic food environment is common in secondary-school and first-year university syllabi. It links to neighbouring topics Food safety, so understanding it makes those chapters shorter.
In everyday life
Look for Toxic food environment outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Toxic food environment in simple terms?

A food environment is the "physical presence of food that affects a person's diet, a person's proximity to food store locations, the distribution of food stores, food service, and any physical entity by which food may be obtained, or a connected system that allows access to food". The term toxic fo…

Why does Toxic food environment matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.
