The Effects of Processed Meat on Lung Function
If the nitrites in foods like ham and bacon cause lung damage, what about “uncured” meat with “no nitrites added”?

The most comprehensive and systematic analysis of the causes of death involved nearly five hundred researchers from more than three hundred institutions in fifty countries and examined nearly one hundred thousand data sources. The landmark Global Burden of Disease Study found that processed meat, including bacon, is blamed for the deaths of more than eight hundred thousand people every year. Worldwide, that’s four times more people than who die from illicit drug use.
Aside from the high saturated fat and sodium content typical in processed meats, what else might these products contain that are harmful to our health?
Although fresh meat consumption has also been associated with cancer and some other chronic diseases, processed or cured meats may be particularly harmful. The NIH-AARP study of more than five hundred thousand Americans suggested that 20 percent of heart disease deaths among American women could be averted if the highest consumers of processed meat would cut down to the equivalent of less than a half strip of bacon a day. No wonder the American Institute for Cancer Research recommends that you simply “avoid processed meat such as ham, bacon, salami, hot dogs and sausages.”
What about that enticing aroma of sizzling bacon? The fumes produced by frying bacon contain a class of carcinogens called nitrosamines. Although all meat may release potentially carcinogenic fumes, processed meat like bacon may be the worst: A 1995 study found that its fumes cause about four times more DNA mutations than the fumes from beef patties fried at similar temperatures.
What’s more, a twin pair of studies from Columbia and Harvard Universities found that consumption of cured meat—like bacon, bologna, ham, hot dogs, sausage, and salami—may increase the risk of COPD. It’s thought to be due to the nitrite preservatives in meat, which may mimic the lung-damaging properties of the nitrite by-products of cigarette smoke.

Laboratory models suggest that extreme doses of heme iron may be detrimental, but what about the effects of nutritional doses in humans? A look at heme’s carcinogenic effects.
Is heme just an innocent bystander in the link between meat intake and breast cancer, diabetes, heart disease, stroke, and high blood pressure?
We have an uncanny ability to pick out the subtle distinctions in calorie density of foods, but only within the natural range.
Breakthroughs in the field of chronobiology—the study of our circadian rhythms—help solve the mystery of the missing morning calories in breakfast studies.
Oxidized cholesterol (concentrated in products containing eggs, processed meat, and parmesan cheese) has cancer-fueling estrogenic effects on human breast cancer.
Dairy is compared to other foods for cardiovascular (heart attack and stroke) risk.
What happened when researchers tried to tease out what’s in dairy that interferes with the health benefits of berries and tea?
Chicken, fish, and egg powder in processed foods present greater risk from cholesterol oxidation byproducts, but there are things you can do to reduce exposure.
In this video, I explain my traffic light system for ranking the relative healthfulness of Green Light vs. Yellow Light vs. Red Light foods.
Even at low-level exposure, arsenic is not just a class I carcinogen, but may also impair our immune function and increase our risk of cardiovascular disease and diabetes.
Açaí berries are touted for their antioxidant power, but does that translate into increased antioxidant capacity of your bloodstream when you eat them?
