Is Processed Meat Safe? New Study Finds No Safe Amount for Your Health

Paula Gallagher on 07/08/2025

Most of us already know that processed meats—like bacon, hot dogs, and deli slices—aren’t doing our health any favors. They've been linked to cancer, heart disease, and even cognitive decline. But a new large-scale analysis published in Nature Medicine goes a step further: it suggests there may be no safe level of processed meat consumption when it comes to serious health risks like type 2 diabetes and colorectal cancer.

New Research Confirms the Risks of Processed Meat

What the Study Found About Disease Risk

Researchers at the University of Washington analyzed over 70 high-quality studies involving millions of participants. Their focus? How ultra-processed foods—especially processed meats—impact the risk of developing type 2 diabetes, ischemic heart disease, and colorectal cancer.

Among all the ultra-processed foods studied—such as sugary drinks and foods with trans fats—processed meats stood out as having the strongest link to increased disease risk. Even small amounts made a measurable impact:

One hot dog per day was linked to an 11% higher risk of type 2 diabetes
That same daily intake was associated with a 7% increased risk of colorectal cancer

That same amount increased the risk of colorectal cancer by at least 7%.

What Is Considered Processed Meat?

Common Examples of Processed Meats

Processed meats are defined as meat products preserved by smoking, curing, salting, fermenting, or adding chemical preservatives. Common examples include:

Bacon
Hot dogs
Ham
Sausages
Salami
Corned beef
Deli meats
Jerky
Canned meats

These processing methods often introduce compounds like nitrates and nitrites, which are linked to oxidative stress, inflammation, and cellular damage over time.

Is There Any Safe Amount of Processed Meat?

According to the study, the answer is probably not.

What makes this research especially significant is its use of the Burden of Proof Risk Function—a conservative statistical model that minimizes overestimation. This means the risks reported are likely underestimates, not exaggerations.

“Habitual consumption of even small amounts of processed meat, sugary drinks, and trans fatty acids is linked to increased risk of developing type 2 diabetes, ischemic heart disease, and colorectal cancer.”
— Dr. Demewoz Haile, Lead Researcher

Processed Meat vs. Other Ultra-Processed Foods

Risk Comparisons: Soda, Trans Fats & More

While processed meats showed the strongest health impact, the study also highlighted risks from other ultra-processed foods:

Drinking one can of sugary soda per day was associated with an 8% higher risk of type 2 diabetes and a 2% higher risk of heart disease.
Even small daily amounts of trans fats increased the risk of ischemic heart disease by 3%.

These may seem like small percentages, but across large populations and over time, they contribute to a significant burden of chronic disease.

How to Reduce Your Risk and Eat Healthier

Reducing your intake of processed foods—especially processed meats—can meaningfully improve long-term health outcomes. Here are a few ways to get started:

Better Protein Choices to Replace Processed Meats

Opt for lean, whole food proteins like:
- Grilled chicken or turkey breast
- Salmon, tuna, or other fatty fish
- Eggs, legumes, lentils
- Plant-based options like tofu and tempeh

Supplement Support for Detox and Inflammation

Processed meat consumption increases the body’s toxic load and inflammation. To counter this:

Support detox with:
- Vitamin C
- Glutathione
- NAC (N-acetylcysteine)
- Fiber-rich formulas that help bind and eliminate toxins

The message is clear: processed meats aren’t just “sometimes” foods—they’re best avoided altogether when possible.

While convenience and taste make these foods tempting, the long-term health costs are becoming increasingly difficult to ignore. By focusing on whole, nutrient-dense foods, you can reduce your risk for chronic disease and feel better every day.
