Frozen foods are a convenient staple in many households, but not all of them are as safe as they seem. While freezing can preserve nutrients, certain highly processed frozen foods—especially those containing preservatives, additives, and processed meats—have been linked to increased cancer risk. Ingredients like nitrates, nitrites, and artificial additives, commonly found in frozen meals and snacks, may contribute to chronic inflammation and the formation of carcinogenic compounds. Knowing which frozen options to limit can help you make healthier choices for long-term well-being.
According to dietitian Alyssa Tatum in an article from the MD Anderson Cancer Center, some of the worst options are frozen hot dogs, sausages, pizza, and more. Read on to learn more!
1. Frozen Hot Dogs
Who doesn't enjoy a hot dog at a cookout from time to time? Especially when the frozen options are so convenient. If you're looking to stay as healthy as possible, though, it's crucial not to eat this processed meat in excess. Hot dogs are another processed meat that is high in nitrates and nitrites, which contribute to cancer risk. As with other processed meats, Tatum suggests opting for nitrite-free versions or exploring healthier alternatives, especially if you eat hot dogs regularly.

2. Frozen Sausages
Frozen sausage, another processed breakfast meat, carries similar risks due to the preservatives. These are typically used to enhance its flavor and shelf life. Instead of reaching for your go-to sausage, it's best to swap this meat out for healthier options if you want to reduce your risk of cancer. Always check the nutrition label and go for choices with fewer additives. "I recommend seeing if there are healthy swaps available for that food and reading labels to compare products," Tatum says.

3. Bacon
Wake up and smell the bacon—but maybe don't eat too much of it, especially with frozen varieties that aren't necessarily fresh. This tasty breakfast staple is highly processed! Tatum says that this processed meat has also been associated with increased cancer risk because bacon often contains nitrates and nitrites, which can contribute to colorectal and stomach cancers. "These options are often preserved using nitrates and nitrites, which can increase the risk of colorectal and stomach cancers," she explains. If you still want to eat bacon from time to time, look for nitrate- and nitrite-free options when available.

4. Frozen Pizzas with Processed Meat Toppings
Pepperoni, sausage, and bacon toppings not only include harmful preservatives, but frozen pizzas can also be high in refined carbs and trans fats, which promote inflammation—a known cancer risk factor.

5. Frozen TV Dinners with Preservatives and Additives
Many frozen meals contain artificial additives, sodium-rich sauces, and preserved meats, all of which can contribute to chronic inflammation and increased cancer risk when eaten regularly. Once in a while if you're too tired or busy won't wort, but opt for eating something fresh for dinner that doesn't include harmful preservatives or additives.
