Americans Continue to Eat Processed Meat Despite Serious Health Warnings
By Dan Gray
Processed foods, in their many delicious forms, are an American favorite.
But new research shows that despite increasing evidence on just how unhealthy processed foods are, Americans have continued to eat the products at the same rate.
A study published in the July edition of Journal of the Academy of Nutrition and Dietetics looked at trends between 1999 and 2016.
Data on nearly 44,000 people shows that over this timespan the amount of processed meat consumed by adults in the U.S. has remained unchanged.
Consumption of healthier meat options such as fish and shellfish also stayed the same.
If there's a silver lining, it's news that Americans are eating more chicken and less red meat than they used to.
Given the acknowledged health risks of consuming processed meats, the data would seem to suggest that Americans are unaware of these dangers.
Experts interviewed by Healthline say the report isn't particularly surprising. They also offer some advice on how to eat better.
What is Processed Meat?
Processed meat isn't hard to identify.
Any meat product that's been altered in some way to add flavor or shelf life is considered processed.
The long list includes certain deli meats, along with hot dogs, sausage, bacon, and ham.
"The World Health Organization (WHO) declared processed red meat to be in the same cancer-causing category as cigarettes and plutonium, so it obviously carries some significant danger," Dr. Andrew Freeman, a cardiologist and director of cardiovascular prevention and wellness at National Jewish Health, told Healthline.
To understand what makes these meats so unhealthy, it helps to look at what's in it.
"A lot of it has to do with the actual components associated with the processing of red meat," explained Kristin Kirkpatrick, MS, RDN, a licensed, registered dietitian who manages wellness nutrition services at the Cleveland Clinic Wellness Institute.
One primary component of processed meat are nitrites and nitrates, components that prevent the growth of bacteria and add a salty flavor.
"A large WHO study showed strong associations between nitrates and nitrites and cancers of the stomach and colon," Kirkpatrick told Healthline. "Just last week, The BMJ found early death associated with processed red meat as well, showing that processed red meat carries much more sodium than unprocessed meat, potentially increasing the risk for hypertension, stroke, and heart attack."
Why Do We Keep Eating It?
Freeman acknowledges one big reason for the popularity of these meat products.
"It tastes really good," he said. "When meats are cured, salted, and spiced, it makes them taste good — although I would argue you can put those same spices on vegetables and make them taste good, too."
Delicious as it is, why aren't more people aware of the risks? The study's lead author believes it has to do with a lack of education.
"While factors other than health (e.g. social, cultural and economic) can influence Americans' food choices, the lack of widespread awareness of health risks associated with processed meat may have contributed to the lack of consumption change in the past 18 years," Dr. Fang Fang Zhang of the Friedman School of Nutrition Science and Policy at Tufts University in Boston, said in a press release.
Freeman agrees, saying it's good business for major food producers to downplay the risks and continue marketing their products. In this way, processed meat is pervasive in the U.S.
"The clincher is that these products are served in healthcare institutions," he said. "You can walk into a large majority of hospital systems in this country and get bacon, eggs, salami, whatever. If you see that stuff served everywhere and see fast food commercials, it's hard to realize that there could be harm.
He also points out that while other carcinogenic products such as cigarettes have warning labels, processed meats contain no such caution.
"If you go to the store right now, there's nothing on the packaging saying this product may be associated with cancer, or with heart disease for that matter, sadly," Freeman said. "It doesn't surprise me that the study showed no change and it should be a warning to us that we really need to do a much better effort at raising awareness of the risks of consuming these products regularly."
How Much is Too Much?
For anyone who loves a hot dog at the ballpark or sausages at a summer cookout, the idea of dropping processed meat entirely may seem daunting.
A diet that includes no processed meat is ideal, but it can be enjoyed as an occasional treat.
Kirkpatrick says that eating processed meat even once a day is "way too much."
"Many experts would say never eating processed meat is acceptable, but if we look at the studyTrusted Source in The BMJ, participants were grouped by consumption and the lowest consumption — less than six times per month, or none at all — had better outcomes. I tell my patients to look at red processed meat the same way they do dessert — a few times a month as a treat."
For carnivores wary of moving to a fully plant-based diet, there are healthier meat-based options available.
"Fish is a fabulous source of protein and lots of fish is high in omega-3 fatty acids, which may be protective to health," said Kirkpatrick. "Wild line-caught salmon, wild trout, and sardines are some of the best."
Making change on an individual level requires willpower, but it is still relatively straightforward. Changing things on a societal level constitutes a much bigger task.
Prior studies have shown the health risks of processed meats. But this most recent study, one that shows societal trends, could help move the needle in the right direction.
"Findings of this study can inform public health policy priorities for improving diet and reducing chronic disease burden in the U.S.," said Zhang. "Because stores and fast food restaurants are the main purchase locations for processed meat, future policies may prioritize these as primary sites of intervention for reducing processed meat consumption among U.S. adults."

After sustained declines in the number of COVID-19 cases over recent months, restrictions are starting to ease across the United States. Numbers of new cases are falling or stable at low numbers in some states, but they are surging in many others. Overall, the U.S. is experiencing a sharp increase in the number of new cases a day, and by late June, had surpassed the peak rate of spread in early April.
Seven day rolling average of number of people confirmed to have COVID-19, per day (not including today). This chart gets updated once per day with data by Johns Hopkins. Johns Hopkins university doesn't provide reliable data for March 12 and March 13. Johns Hopkins CSSE Get the data
To Have a Second Wave, the First Wave Needs to End.<p>A wave of an infection describes a large rise and fall in the number of cases. There isn't a precise epidemiological definition of when a wave begins or ends.</p><p>But with talk of a <a href="https://www.theguardian.com/world/2020/jun/27/new-covid-19-clusters-across-world-spark-fear-of-second-wave" target="_blank">second wave in the news</a>, as an <a href="https://www.american.edu/cas/faculty/mhawkins.cfm" target="_blank">epidemiologist and public health researcher</a>, I think there are two necessary factors that must be met before we can colloquially declare a second wave.</p><p>First, the virus would have to be controlled and transmission brought down to a very low level. That would be the end of the first wave. Then, the virus would need to reappear and result in a large increase in cases and hospitalizations.</p><p>Many countries in <a href="https://doi.org/10.1038/s41562-020-0908-8" target="_blank">Europe and Asia have successfully ended the first wave</a>. <a href="https://www.theguardian.com/world/2020/jun/08/new-zealand-abandons-covid-19-restrictions-after-nation-declared-no-cases" target="_blank">New Zealand</a> and <a href="https://www.newyorker.com/magazine/2020/06/08/how-iceland-beat-the-coronavirus" target="_blank">Iceland</a> have also made it through their first waves and are now essentially coronavirus-free, with very low levels of community transmission and only a handful of active cases currently.</p>
Different States, Different Trends<p>Looking at U.S. numbers as a whole hides what is really going on. Different states are in <a href="https://www.nytimes.com/interactive/2020/us/coronavirus-us-cases.html" target="_blank">vastly different situations right now</a> and when you look at states individually, four major categories emerge.</p><ol><li>Places where the first wave is ending: States in the Northeast and a few scattered elsewhere experienced large initial spikes but were able to mostly contain the virus and substantially brought down new infections. <a href="https://www.nytimes.com/interactive/2020/us/new-york-coronavirus-cases.html" target="_blank">New York</a> is a good example of this.</li><li>Places still in the first wave: Several states in the South and West – see <a href="https://www.nytimes.com/interactive/2020/us/texas-coronavirus-cases.html" target="_blank">Texas</a> and <a href="https://www.nytimes.com/interactive/2020/us/california-coronavirus-cases.html" target="_blank">California</a> – had some cases early on, but are now seeing massive surges with no sign of slowing down.</li><li>Places in between: Many states were hit early in the first wave, managed to slow it down, but are either at a plateau – like <a href="https://www.nytimes.com/interactive/2020/us/north-dakota-coronavirus-cases.html" target="_blank">North Dakota</a> – or are now seeing steep increases – like <a href="https://www.nytimes.com/interactive/2020/us/oklahoma-coronavirus-cases.html" target="_blank">Oklahoma</a>.</li><li>Places experiencing local second waves: Looking only at a state level, <a href="https://www.nytimes.com/interactive/2020/us/hawaii-coronavirus-cases.html" target="_blank">Hawaii</a>, <a href="https://www.nytimes.com/interactive/2020/us/montana-coronavirus-cases.html" target="_blank">Montana</a> and <a href="https://www.nytimes.com/interactive/2020/us/alaska-coronavirus-cases.html" target="_blank">Alaska</a> could be said to be experiencing second waves. Each state experienced relatively small initial outbreaks and was able to reduce spread to single digits of daily new confirmed cases, but are now all seeing spikes again.</li></ol><p>The trends aren't surprising based on how states have been dealing with reopening. The virus will go wherever there are susceptible people and until the U.S. stops community spread across the entire country, the first wave isn't over.</p>
What Could a Second Wave Look Like?<p>It is possible – though at this point it seems unlikely – that the U.S. could control the virus before a vaccine is developed. If that happens, it would be time to start thinking about a second wave. The question of what it might look like depends in large part on everyone's actions.</p><p>The <a href="https://dx.doi.org/10.1086%2F592454" target="_blank">1918 flu pandemic</a> was characterized by a mild first wave in the winter of 1917-1918 that went away in summer. After restrictions were lifted, people very quickly went back to pre-pandemic life. But a second, deadlier strain came back in fall of 1918 and third in spring of 1919. In total, <a href="https://www.cdc.gov/flu/pandemic-resources/1918-commemoration/1918-pandemic-history.htm" target="_blank">more than 500 million people were infected</a> worldwide and upwards of <a href="https://theconversation.com/compare-the-flu-pandemic-of-1918-and-covid-19-with-caution-the-past-is-not-a-prediction-138895" target="_blank">50 million died</a> over the course of three waves.</p><p>It was the combination of a quick return to normal life and a mutation in the flu's genome that made it more deadly that led to the horrific second and third waves.</p><p>Thankfully, the coronavirus appears to be much more <a href="https://doi.org/10.1016/j.meegid.2020.104351" target="_blank">genetically stable</a> than the influenza virus, and thus less likely to mutate into a more deadly variant. That leaves human behavior as the main risk factor.</p><p>Until a <a href="https://theconversation.com/what-needs-to-go-right-to-get-a-coronavirus-vaccine-in-12-18-months-136816" target="_blank">vaccine or effective treatment is developed</a>, the tried-and-true public health measures of the last months – <a href="https://theconversation.com/this-simple-model-shows-the-importance-of-wearing-masks-and-social-distancing-140423" target="_blank">social distancing,</a> <a href="https://theconversation.com/masks-help-stop-the-spread-of-coronavirus-the-science-is-simple-and-im-one-of-100-experts-urging-governors-to-require-public-mask-wearing-138507" target="_blank">universal mask wearing</a>, frequent hand-washing and avoiding crowded indoor spaces – are the ways to stop the first wave and thwart a second one. And when there are surges like what is happening now in the U.S., further reopening plans need to be put on hold.</p>

Gluts of food left to rot as a consequence of coronavirus aren't just wasteful – they're also likely to damage the environment.
Methane on the Rise<p>Not only is this a tragic waste of food at a time when many are going hungry, it is also an <a href="https://donatedontdump.net/2014/07/07/the-effects-of-food-waste-on-the-environment-by-junemy-pantig/" target="_blank">environmental hazard</a> and could contribute to global warming. Landfill gas – <a href="https://www.epa.gov/lmop/basic-information-about-landfill-gas" target="_blank">roughly half methane and half carbon dioxide (CO2)</a> – is a natural byproduct of the decomposition of organic material.</p>
Food decay leads to production of greenhouse gases, methane and carbon dioxide. EPA<p>Methane is a potent greenhouse gas, 28 to <a href="https://www.ipcc.ch/site/assets/uploads/2018/02/SYR_AR5_FINAL_full.pdf" target="_blank">36 times more effective than CO2 at trapping heat</a> in the atmosphere over a 100-year period, according to the Intergovernmental Panel on Climate Change.</p><p>"Many export-oriented producers produce volumes far too large for output to be absorbed in local markets, and thus <a href="https://unctad.org/en/pages/newsdetails.aspx?OriginalVersionID=2333" target="_blank">organic waste levels have mounted substantially</a>," says Robert Hamwey, Economic Affairs Officer at UN agency UNCTAD. "Because this waste is left to decay, levels of methane emissions, a greenhouse gas, from decaying produce are expected to rise sharply in the crisis and immediate post-crisis months."</p>
Food supply chains are easily disrupted. UN FAO<p>Dumping food was already a problem before the crisis. In America alone, <a href="https://www.refed.com/?sort=economic-value-per-ton" target="_blank">$218 billion is spent growing, processing, transporting</a> and disposing of food that is never eaten, estimates ReFED, a collection of business, non-profit and government leaders committed to reducing food waste. That's equivalent to around 1.3% of GDP.</p><p>Since the pandemic took hold, <a href="https://www.bbc.co.uk/news/world-52267943" target="_blank">farmers are dumping 14 million liters</a> of milk each day because of disrupted supply routes, estimates Dairy Farmers of America. A chicken processor was forced to <a href="https://www.nytimes.com/2020/04/11/business/coronavirus-destroying-food.html" target="_blank">destroy 750,000 unhatched eggs a week</a>, according to the New York Times, which also cited an onion farmer letting most of his harvest decompose because he couldn't distribute or store them.</p>
Food Prices Collapsing<p>The excess has also seen prices collapse. The <a href="http://www.fao.org/worldfoodsituation/foodpricesindex/en/" target="_blank">FAO Food Price Index</a> (FFPI) averaged 162.5 points in May 2020, down 3.1 points from April and reaching the lowest monthly average since December 2018. The gauge has dropped for four consecutive months, and the latest decline reflects falling values of all the food commodities – dairy, meat, cereal, vegetable – except sugar, which rose for the first time in three months.</p><p>All this while the pandemic is exacerbating other global food trends.</p><p>"This year, some 49 million extra people may fall into extreme poverty due to the COVID-19 crisis," said António Guterres, Secretary-General of the UN. "The number of people who are acutely food or nutrition insecure will rapidly expand. <a href="https://www.youtube.com/watch?v=fGhLKAbNDiY&feature=youtu.be" target="_blank">Even in countries with abundant food, we see risks of disruptions in the food supply chain</a>."</p>
