4 Foods To AVOID After Cancer

If you've recently completed cancer treatment, you may find yourself overwhelmed by the sheer volume of information about how to stay cancer-free. Researching on your own can be confusing, especially when it comes to knowing what to eat and what to avoid. But as a cancer recovery and prevention naturopathic doctor, I'm here to simplify it for you. By focusing on small, manageable changes, you can take steps to reduce your risk of cancer recurrence and live a joyful life (one where you aren’t constantly thinking about cancer!).

One of the most powerful places to start? Your diet

Certain foods can promote cancer growth, and avoiding them is one key way to support your health. Below are four foods and drinks I recommend my clients avoid consuming. These aren't just suggestions; they're based on research that links them to increased cancer risk. I'll also provide alternatives to help you make healthier choices without feeling deprived.

1. Deli Meats

It might seem harmless to grab a sandwich or enjoy a charcuterie board, but deli meats, including ham, salami, and hot dogs, have been directly linked to cancer risk. These processed meats often contain preservatives like nitrates and nitrites, which have been found to cause cancer. Even products labeled as nitrate or nitrite free can contain compounds within them that get converted into nitrates or nitrites when they're cooked.

The American Institute for Cancer Research (AICR) reports that even a small amount of processed meat, about 50 grams (less than two slices of bacon), eaten daily can increase the risk of colorectal cancer by 16%. It's good to note that that is eating 50g EVERY day, but it is likely that consuming deli meats now and then is safe (but we have everyone to fill up on healthier options more often and find replacements for processed meats when they can).

Instead, opt for whole, unprocessed sources of protein. Grilled chicken breasts, canned tuna, legumes, and hummus are all fantastic alternatives that can provide the protein your body needs without the added cancer risk. You can still enjoy delicious meals while reducing your cancer-promoting environment.

Why it matters: Processed meats are classified as Group 1 carcinogens by the World Health Organization, meaning they’re known causes of cancer. Eliminating them from your diet is a significant step toward reducing your risk of cancer coming back.

2. Alcohol

It might be tempting to enjoy a glass of wine after a long day, but the unfortunate truth is that there is no known safe level of alcohol consumption when it comes to cancer. Alcohol is a known carcinogen and has been linked to an increased risk of many types of cancer, including breast, liver, and colorectal cancer. For those who have already gone through cancer treatment, continuing to drink alcohol can increase the risk of recurrence (click here to read my article on alcohol).

If cutting alcohol out completely feels daunting, try starting by reducing your intake (great reductions have been seen in reducing cancer risk simply by reducing one's intake). You might also find non-alcoholic alternatives like sparkling water or herbal teas just as satisfying. Small changes to your habits—like switching to a refreshing mocktail or flavored soda water—can help you feel empowered without risking your health.

Why it matters: Alcohol has a direct link to cancer recurrence, so eliminating it or significantly reducing your consumption can help protect you from cancer-promoting effects.

3. Sugary Beverages, Like Juice

Sweetened juices and other sugary drinks may seem harmless, but they come with hidden dangers. These beverages are often loaded with sugar and empty calories, contributing to weight gain and increased inflammation—both of which are factors that can promote cancer growth.

Juice, while sometimes seen as a healthier alternative, often lacks the fiber of whole fruits and is primarily composed of sugar. If you're a fan of green vegetable juices, make sure to consume them with meals to minimize blood sugar spikes.

Try swapping sugary drinks for healthier alternatives like herbal teas, unsweetened flavored water, or even creating your own beverages with fruit and herbs. Over time, you'll find that these changes help you break the craving for sweetened drinks, while also reducing your exposure to cancer-promoting foods.

Why it matters: Reducing sugar intake is one of the best ways to lower your cancer recurrence risk, as excess sugar can fuel inflammation and cancer growth.

4. Soda (Including Diet Sodas)

Soda and other sugary beverages not only contribute to obesity, which increases cancer risk, but the chemicals found in some of these drinks, like artificial sweeteners and colorings, have been under scrutiny for their potential cancer-promoting effects. Diet sodas don't seem to have the same direct link to cancer according to research. We encourage our clients to see what they can do to reduce their diet soda intake and save it for special occasions, although it can be a good replacement for someone who has big cravings for a regular sugar-filled soda.

Breaking the soda habit might be easier than you think. Replace soda with healthier drinks, such as sparkling water infused with fruits and herbs or herbal teas. Or, if you're used to drinking soda at certain times (like during TV shows or while driving), consider switching up your routine. Taking a walk, doing light stretches, or even finding new shows to enjoy could help you change your habits and avoid cravings that would typically get triggered with these activities.

Why it matters: Eliminating sugary drinks and limiting even diet sodas can help you reduce your exposure to chemicals and additives that may promote a cancer-friendly environment in your body.

Nutrition and Cancer: The Bigger Picture

What you eat can profoundly influence how you recover from cancer treatment and how likely cancer is to return. Foods that are high in sugar, unhealthy fats, or artificial additives can promote inflammation in the body, which in turn can create an environment that supports cancer growth.

By choosing an anti-cancer diet that prioritizes whole, unprocessed foods, you can not only reduce inflammation but also boost your immune system, enhance your body's healing process, and feel more energetic and confident in your health.
