Do We Need Junk Food Taxes?

Updated on March 25, 2020

I've spent half a century (yikes) writing for radio and print—mostly print. I hope to be still tapping the keys as I take my last breath.

Potato chips are yummy, loaded with fat, calories, and salt, and have very little nutritional value. By eating chips, sweetened baked goods, and other junk foods people risk poor health outcomes. Society as a whole pays a stiff price treating illnesses caused by poor dietary choices. So why not tax junk food to steer people away from harmful foods?

Defining Junk Food

Nobody would accuse a stick of celery of being junk food, but an artificial cream-filled cake certainly is.

But, there is no clear dividing line between healthy and unhealthy food. Dr. Sunali Sharma is a dietitian and nutritionist with Amandeep Hospital in Amritsa, India. She gives us the broad brushstrokes of junk food “Commercial products including but not limited to salted snack foods, gum, candy, sugary desserts, fried fast food, and sweetened carbonated beverages that have little or no nutritional value but are high in calories, salt, and fats may be considered junk foods.”


Without a clear and measurable definition, taxing junk food would be fraught with difficulties.

Some items are obvious: sugary pop is of little nutritional value and would be taxed, while lettuce, tomatoes, and green onions would escape. But, what happens when you put dollops of high-fat, high-salt salad dressing on those veggies? Hamburgers contain protein along with the artery-clogging fat. How can a fair tax be levied here?

So, a huge bureaucracy might be needed to decide which foods should be taxed and at what rate. An equally large food industry lobby would likely be created to fight for decisions favouring certain product lines.

To burn off the calories of a Chipotle Burrito you would have to do push-ups for 140 minutes.

The High Cost of Junk Food

One of the major negative effects of junk food is that it frequently leads to obesity; and obesity is widespread and very costly. The National Health and Nutrition Examination Survey (2017-18) gives us these numbers for Americans:

  • “In 2017–2018, the age-adjusted prevalence of obesity in adults was 42.4%, and there were no significant differences between men and women among all adults or by age group.
  • “The age-adjusted prevalence of severe obesity in adults was 9.2% and was higher in women than in men.
  • “Among adults, the prevalence of both obesity and severe obesity was highest in non-Hispanic black adults compared with other race and Hispanic-origin groups.
  • “The prevalence of severe obesity was highest among adults aged 40–59 compared with other age groups.
  • “From 1999–2000 through 2017–2018, the prevalence of both obesity and severe obesity increased among adults.

According to the National League of Cities “The estimated annual health care costs of obesity-related illness are a staggering $190.2 billion or nearly 21% of annual medical spending in the United States.”

Health Canada puts the cost at between $4.6 billion to $7.1 billion and adds that obesity is associated with “type 2 diabetes, asthma, gallbladder disease, osteoarthritis, chronic back pain, several types of cancers (colorectal, kidney, breast, endometrial, ovarian, and pancreatic cancers) and major types of cardiovascular disease (hypertension, stroke, congestive heart failure, and coronary artery disease).”

The government in the United Kingdom says obesity knocks an average of nine years off life expectancy and “The overall cost of obesity to wider society is estimated at £27 billion” ($34 billion).


Pigouvian Taxes

Arthur Pigou (1877-1959) was an English economist whose work gave rise to so-called “sin taxes.” The Concise Encyclopedia of Economics notes that Pigou “developed Alfred Marshall’s concept of externalities, costs imposed or benefits conferred on others that are not taken into account by the person taking the action.”

He said that a company creating pollution should pay a tax to cover the health cost to society of the insult to the environment. On the other hand, people educating themselves should be subsidized as they are creating a benefit to society.

Taxes levied to compensate society for some sort of negative behaviour are called Pigouvian taxes. The health costs of tobacco and alcohol addiction are, to some extent, covered by the taxes raised on these items. Gambling is taxed in many jurisdictions because addiction can lead to theft to cover loses and family breakdown.


Excise Tax

Tufts and New York Universities released a study on junk food taxation in 2018. Researchers concluded that “a federal junk food tax appears feasible based on product categories or combination category-plus-nutrient approaches, using a manufacturer excise tax, with additional support for sugar and graduated tax strategies.”

Consumers would not pay the tax at the point of purchase, but they would pay it anyway because manufacturers would pass it on. However, food companies would no doubt see the benefits of cutting their tax burden by reducing the amount of harmful ingredients in their products.

One of the study’s authors, Renata Micha, RD, PhD, says “Junk food taxes have the potential to substantially reduce the disease burden that results from unhealthy food and beverage consumption in the United States.”

Junk Food Tax Downside

Numerous studies, including one by the National Bureau of Economic Research have shown that food price increases take a long time to affect weight.

The authors write “… that policies raising the price of calories will have little effect on weight in the short term, but might curb the rate of weight growth and achieve weight reduction over a very long period of time.” The time scale here is 30 years.

To burn off the calories of a Whopper Burger you would have to do curl-ups for 89 minutes.

Also, raising the price of certain foods through taxes might work against engaging in healthy exercise. A paper published in The Journal of Public Economics in June 2009 suggests higher fast-food prices will cause people to switch to buying raw ingredients and cooking more meals at home. Surely, that’s a good thing. Maybe not, say the paper’s authors. Home food preparation takes more time and therefore leaves less time for exercise, which is a vital component of the battle against obesity.

And, there’s the libertarian argument that the nanny state should not be interfering in the food choices of the population.


Bonus Factoids

  • In 2011, Denmark introduced a tax on high-fat foods including pizza and butter and Hungary has imposed a tax on foods with unhealthy levels of sugar, salt, caffeine, and carbohydrates. Denmark cancelled its taxes after massive pressure from the food industry.
  • In 2013, New York City’s Mayor Michael Bloomberg proposed a ban on soft drinks in cups larger than 16 oz (473 ml), that’s the size of a “small” pop at McDonald’s. The howls of protest ended up in a court ruling that struck down the ban.
  • Until 2012, the 7-11’s chain was selling Double Big Gulps sodas measuring 64 ounces (1.9 L). Responding to criticism, the company reduced the size to 50 ounces (1.5 L). The smaller drink is only one-and-a-half times bigger than the average adult’s stomach.

To burn off the calories of one KFC Drumstick, just one drumstick not a bucket of fried chicken, you would have to do pull-ups for 12 minutes.

      I don't think the government has the right to tell people what to eat, and I also think that the people who overeat will do so regardless of the tax. Certainly obesity causes many health problems, and I believe most people know that. If only it was so simple!

      This is a hot topic in the UK at the moment. Obesity is an issue, but will a tax on junk food bring about cries against a nanny state?

      Well, they've not long started taking sugary drinks like Cola in the UK. Diet drinks are cheaper to try and sway people into buying these. I can see how this would be a good idea. Whether it would work or not, I don't know.

      Well, You keep writing about food and Mr. Wesman and I will be here for sure, haha!!

      Mr. Wesman, yes! Let's put some taxes on those chips. Your dad will eat less and the world will be that much better for it. Haha!!

      “Commercial products including but not limited to salted snack foods, gum, candy, sugary desserts, fried fast food, and sweetened carbonated beverages that have little or no nutritional value..." - This is very true and I would like to ask: when is the last time You saw an advertisment for brocolli, or carrots? Never most likely and because they're not addictive. They sell us all the sweet and salty stuff because we become addicted to it. It's $%^#ing brutal! Might just well sell us some cocaine with that chocolate bar.

      "Food is Medicine" say the Elders. When You end-up in the hospital, that's too late! Food is our medicine, daily. If people only understood this.

      "Home food preparation takes more time and therefore leaves less time for exercise, which is a vital component of the battle against obesity" - Ya, but if You don't eat junk, You're gonna need less time for cardio. If You don't pig out on a cake yourself (not speaking of You personally here, just in general) then, You don't need to run five miles, necessarily (I just made-up the numbers here but You get the point).

      From Mr. Wesman's comment: " It's clear to me government, always on the take from lobbyist, has no business telling people what to eat". - Well, when we're all paying your bill at the hospital (this is for Canadians and Europeans, not Americans), there should be rules. You can;t poison yourself daily and expect taxpayers to cough-up the bill. That's why I don;t complain about cigarette prices. They are through the roof but they are unhealthy so, yes charge me lots. I deserve it lol

      "To burn off the calories of one KFC Drumstick, just one drumstick not a bucket of fried chicken, you would have to do pull-ups for 12 minutes." - Wow! Am I ever glad I don't eat that crap. On top of which, God knows how those chikens were raised, how much antibiotics they ate and so on.

      Good article. Food for thought.

      All during my youth government slandered fat, especially animal fat, as an unhealthy thing to eat. None of that was true. It's clear to me government, always on the take from lobbyist, has no business telling people what to eat. So it's a big 'NO' from me on the question of junk food taxes. I do have to admit, however, I wish the price of potato chips were so high my dad would stop buying and eating them.

      I've got another plate of chicken and brown rice to eat, and then I've got to decide what wonderful thing I shall prepare for myself next. I'm very poor, but I prioritize eating well at the top of my list. Decisions decisions.
