When it comes to lowering your risk of cancer, what you add to your plate can make a meaningful difference.

Jeanna Rich, an oncology registered dietitian with OSF Cancer Support Services, says the key is nourishing the body with whole grains, colorful fruits and vegetables, fiber-rich foods and Omega-3s.

As someone who works closely with cancer patients, Rich encourages people to think of food as a daily opportunity to fuel the immune system and support long-term health.

Why fiber matters

Most Americans fall short on fiber; a nutrient vital for good gut bacteria, healthy digestion and lowering the risk of colorectal cancer.

Rich says increasing fiber can be simple. Start by working whole grains into meals: oats, wild rice, flax seed, walnuts, pumpkin seeds and chia seeds. They can easily be sprinkled onto cottage cheese, Greek yogurt or oatmeal to boost texture and nutrition.

Research backs up these benefits. A large group of researchers from 15 international cohort studies, including scientists from the American Cancer Society (ACS), analyzed data from more than 842,000 men across North America, Europe, Australia and Asia. Their findings suggest that dietary fiber may lower the risk of developing advanced and aggressive forms of prostate cancer. Additional ACS findings note that whole grains may help fight against advanced prostate cancer.

Rich offers a practical approach to building a fiber-forward breakfast.

"Another great way to add fiber is with our yogurt. A lot of us make yogurt parfaits, but here's a way to take it to the next level. Add chia seeds, flax seeds, pumpkin seeds and walnuts," Rich says. "Top them with berries, which contain a ton of fiber."

Berries – whether fresh or frozen – are packed with vitamins, antioxidants and deep pigments that signal high nutrient content. Rich recommends buying frozen berries and storing them in the fridge to thaw, making them easy to add into yogurt, cottage cheese or morning oatmeal. Frozen produce can be a cost-effective option, especially when items are out of season, Rich says. Thanks to the flash-freezing process, these foods retain their nutrients and offer the same high-quality nutrition as fresh varieties, she adds.

Other high-fiber additions include quinoa, lentils and canned beans, which are paired well with salads, vegetables and hearty meals.

The power of Omega-3s

Omega-3 fatty acids play a crucial role in reducing inflammation and strengthening immune cells.

Some plant-based Omega-3s are found in foods like ground flax seed, but Rich notes that fish-based sources are more efficiently used by the body.

"Some Omega-3s will be found in ground flax seed. However, your body doesn't utilize it as effectively. So, you want to go for those Omega-3s, found in salmon. Keep it frozen in your freezer and choose products that are wild caught. That will have a higher concentration of Omega-3s," Rich says. "Omega-3s help decrease inflammation in our body and increases our fighter cells, so it's a wonderful way to protect from chronic disease and cancer."

Salmon can easily be added into breakfast dishes, salads or purchased as salmon patties. Canned sardines are another convenient, nutrient-dense option.

A need for more vegetables, and more variety

Despite growing awareness of the benefits of produce, Americans still struggle to get enough vegetables into their diet.

"A lot of us are not getting enough vegetables. Many Americans are getting a decent amount of fruit, but vegetables are the tricky ones. When it comes to veggies, diversity is key," Rich says. "On average, most of us only use the same 10 vegetables in our eating routine."

Rich encourages using easy steamer bags filled with multiple vegetables. These mixes often include an array of colors – a good sign you're getting a wide range of nutrients that help fight cancer and chronic disease.

The benefits of polyphenols

Colorful fruits and vegetables bring another powerful nutrient group: polyphenols.

"Polyphenols, flavonoids and lycopene are some key words you may be hearing. Those are the things that are activated in your body and helping protect you," Rich says. "Polyphenols are becoming very popular and are in studies about the gut microbiome. That is considered a source of prebiotics, as well. All these different colors can help feed that good bacteria that helps your immune system be healthy."

Lycopene – found in red and orange produce like tomatoes and peppers – is known to help protect against prostate cancer. Cooked tomatoes are especially beneficial because heat increases lycopene concentration.

Rich suggests adding tomatoes into soups, stews and chili to boost cancer-fighting potential.

What kinds of cancer can a healthy diet protect against?

According to Rich, the right dietary patterns can help protect against a wide range of cancers:

• Breast
• Ovarian
• Gynecologic
• Prostate
• Colorectal
• Gastric

Fiber, Omega-3s and polyphenols are particularly powerful against colorectal and gastric cancers.

Additionally, managing weight through a balanced diet can reduce estrogen production in adipose tissue — a factor that increases breast cancer risk.

Fiber, protein, fruits and vegetables help reduce that risk and help us live a healthier life.

Surprising ways to get more protein

Protein also plays a crucial role in prevention and is especially important for those undergoing treatment.

Rich offers several easy, creative ways to boost protein intake:

• Scrambled eggs: Whisk in cottage cheese to make them “extra fluffy and packed with more protein.”
• Greek yogurt: Blend into red tomato sauce or pasta dishes or use it to make spinach artichoke dip.
• Oatmeal: Add kefir to boost protein and probiotics, helping reduce blood sugar spikes and inflammation.

Foods and drinks to limit or avoid

To best support your health, Rich recommends minimizing:

• Ultra-processed foods
• Artificial additives
• Alcohol
• Excess red meats
• Color dyes
• Processed meats

These items contribute to inflammation and can increase the risk of several types of cancer.

Not only are these bright red, juicy fruits filled with vitamins and minerals, but they can also lessen the risk of cancer, says Katrina Sommer, an advanced clinical dietitian with OSF HealthCare.

“They have these extra ‘bonus nutrients’ we call phytochemicals. They’re found in plant foods, and these help us fight inflammation and act as an antioxidant. This helps get the free radicals out of there that lessen the risk for cancer development,” Sommer says.

Sommer and her team at the OSF Cancer Institute in Peoria, Illinois work alongside cancer patients on what diet is best for them to fight cancer. She says plant foods play a huge role.

“We know a diet that is mostly plant-based, can help lower our risk for cancer and other diseases like heart disease and diabetes,” Sommer says. “It helps us keep a healthy weight, too.”

What is Lycopene?

“Lycopene is one of those phytochemicals. There’s a lot of different groups of these phytochemicals. One of them is called carotenoids. Carotenoids a lot of times will give the plant food its color. Lycopene is a type of carotenoid and gives the tomato that bright red or orange color,” Sommer says. “Lycopene is also found in watermelon, grapefruit and is the red or pink color you see.”

The National Institutes of Health (NIH) identified 72 human and animal studies and concluded that lycopene contained anti-cancer activities. Now, the NIH says the next step is to identify a population that might benefit from lycopene supplementation.

“It’s been shown that eating tomatoes a couple times a week can help lessen the risk of metastatic prostate cancer,” Sommer adds.

Cook tomatoes and drizzle olive oil

“These need to be absorbed very well in our system. To do that, cook them and you can drizzle olive oil on them so we can absorb those nutrients optimally,” Sommer says.

What if I don’t like tomatoes?

“Think of those tomato foods that are cooked. Tomato sauce or tomato soup are good options. They help absorb the lycopene and carotenoids that are in there. So, it doesn’t just have to be a fresh tomato on a salad, you can eat it cooked as well,” Sommer says.

How can red meat or processed meat affect my risk for cancer?

“Something to consider is how much meat you’re eating, especially red meat and processed meat. Too much of these can raise the risk of developing cancer,” Sommer says. “Same with drinking alcohol. We want to lower the amount of alcohol we drink or avoid it if we can.”

Another food factor to consider if you want to avoid cancer - Sommer says to watch out how much added sugar you have in your diet. Too much added sugar intake can affect our weight in negative ways, while not providing any beneficial nutrition. Sodas are a part of this equation due to the added sugar and lack of beneficial nutrition they offer.

“Eating too much fast food or processed food doesn’t have the nutrients we need. It might not have the fiber we get in the plant foods. It doesn’t really help our bodies fight inflammation or cancer risk, so it can raise the risk for cancer developing,” Sommer says.

Overall, Sommer recommends being more mindful of your overall diet and considering the foods and drinks you’re bringing into your body if you want to do everything you can to prevent cancer.

While this seems straightforward, this isn’t a quantity vs. quality scenario. It’s a mix of both, personalized to everyone in different ways.

A late-phase trial published in the New England Journal of Medicine finds people who follow an exercise program after undergoing surgery and chemotherapy can reduce the risk of cancer recurrence, a new cancer diagnosis or death by 28%. The findings were presented on June 1 at the annual meeting of the American Society of Clinical Oncology (ASCO), focusing on those who had Stage 3 or high-risk Stage 2 colon cancer.

Nathaniel Leman is an exercise physiologist with OSF HealthCare. He works alongside patients with cancer, mapping out plans to keep them exercising, despite a cancer diagnosis.

Exercise is helpful to patients with cancer

During a cancer journey, exercise helps deliver medication through the body as it's intended, because a person's blood vessels are opening, allowing the drugs to get to the areas impacted by cancer better. 

"We know exercise is so beneficial for our bodies. Specifically for patients with cancer who deal with a lot of fatigue, tiredness and low energy," Leman says. "They also deal with a lot of joint and muscle pain, maybe even bone pain. Most of the time they have weakened immune systems as well. There's a lot of things through their treatment journey they'll deal with; weight loss is another one."

How exercise is beneficial for patients with cancer

"Exercising with cardio and strength training is really good for our hearts, lungs, muscles and joints. The benefits also include our mental health, and it helps keep our weight consistent," Leman adds. "It also helps to boost our immune system and keep us healthy for a long time."

Leman and his colleagues rely on recommendations from the American College of Sports Medicine (ACSM) to put together plans for patients with cancer. That includes 150 minutes of moderate, cardiovascular or aerobic (using body’s main muscle groups in repeated motions) exercise per week. This can break down into 30 minutes of exercise, five days a week.

If 30 minutes at one time is too much for a person, feel free to break it down into two 15-minute exercise periods, sprinkled throughout your day. Even three 10-minute periods are beneficial.

The main goal is to just get people to start moving. 

How to start moving

"That includes anything from walking to an aerobic bike on a moderate setting," Leman says. "Walking in a pool and doing light jogs inside the pool is something where we can take that pressure of gravity off."

If people want to achieve vigorous exercise, Lehman recommends 75 minutes a week because of the added pressure that's put on muscles and bones. 

If strength training is more your speed, Lehman recommends two to three days a week. This can include light squats, shoulder press, bicep curls, triceps extensions and rows as a few examples. Make sure to have a day of rest in between. 

Avoid powerlifting during cancer

Power lifting (power clean, heavy squats, deadlift) or exerting too much energy during a cancer journey is something to avoid, Lehman recommends. 

"We don't want to do that type of workout where we're over stressing our body to a point we can't move the next day," Lehman says. "Those athletes train for years and years and years, and they put a lot of fatigue on their body that our patients with cancer just can't handle." 

Marathons, triathlons, Iron Mans and Spartan races should be avoided as well. These extremely tough exercise events would cause too much stress on the bodies of patients with cancer. 

Lehman says exercise is good at lowering the risk of cancer, but it doesn't outright prevent cancer. 

Lehman says there is a difference between an active lifestyle and exercising. A basic active lifestyle can include things like daily chores around the house, but he wants patients to take things a step further and add committed time to exercise specifically. However, if a person is working outside in the yard all day, that can be a great amount of physical activity which could supplement exercise on that specific day.

The European Society of Cardiology reports a sedentary lifestyle for two decades is linked to being two times at risk of premature death, compared to being physically active. The American College of Sports Medicine recommends 8,000 steps a day and says that for every 1,000 added steps per day in people with a sedentary lifestyle, reduces the risk of heart disease and death by 15 percent.

The Peoria, Illinois-based hospital system has brought surgical oncologist Tamara Floyd, MD, to the care team at OSF HealthCare Saint Francis Medical Center in Peoria. Dr. Floyd performs cytoreductive and HIPEC (hyperthermic intraperitoneal chemotherapy) surgeries in Peoria, while also seeing patients in Bloomington and Galesburg.

HIPEC procedures are mostly for patients who have tumors or cancer spread in the abdominal cavity. 

Cancerous tumors are removed through cytoreductive surgery where the surgeon initially attempts to remove as much of the cancer as possible. Surgery is then followed by HIPEC, which is when a heated chemotherapy – at just over 106 degrees Fahrenheit – is administered into the abdomen. The heated chemo is then circulated around the area inside the abdomen to treat any remaining microscopic tumor cells.

HIPEC can be beneficial for several types of cancer patients. The one it benefits the most is LAMN, or low-grade appendiceal mucinous neoplasm. HIPEC is considered a standard of care for patients who have seen their cancer spread into the space in the abdomen that contains the abdominal organs.

These can be appendix, colorectal, and now more data indicates stomach cancer patients may benefit from HIPEC, Dr. Floyd says.

"Additionally with more data, pancreatic cancer is being looked at as well. Even patients with breast cancer. Another cancer that benefits from HIPEC is peritoneal mesothelioma." 

HIPEC can be a viable treatment option at any stage, Dr. Floyd says. But as some people are diagnosed with later stage disease, it can feel like no options are possible. HIPEC changes that.

"It's beneficial to have the option of doing HIPEC, or cytoreductive surgeries, for patients who have peritoneal spread of disease, which for most cancers means it is a stage 4 disease," Dr. Floyd says. "In a lot of instances, if you're talking about stage 4 disease, there aren't a lot of other options."

While HIPEC is a viable option for low-grade cancers, it's also a helpful option for later stage, more aggressive cancers. Patients with signet ring or goblet cell features, which are more aggressive subtypes, can also be treated with HIPEC. 

"Signet ring is one of the subtypes of appendiceal, colon or rectal that can be treated. There are even some subtypes of gastric or stomach cancer that are considered a signet ring or have signet ring features," Dr. Floyd says. "Cytoreductive and HIPEC can be considered for those patients."

Throughout a cancer journey, combining traditional chemotherapy that is administered through IV with HIPEC provides a "synergistic effect" Dr. Floyd says. HIPEC allows the chemotherapy to be administered directly to the cancer cells and kill them that way. 

Dr. Floyd has done one HIPEC at OSF Saint Francis so far and has another planned soon. It's anticipated that within the next year, Dr. Floyd and her team will start to do three to four HIPEC surgeries a month as OSF HealthCare Cancer Institute continues to grow as a destination center.

Patient recovery times can be one to two weeks in the hospital after HIPEC surgery, which is why having this option for Central Illinois patients is so important. It allows the patient and their families to stay close to home, instead of having to travel hours away. Dr. Floyd says the longer travel times can turn patients and their families away from pursuing care. 

Heated chemotherapy can also be used in thoracic cavities. This would then be called HITEC or HITOC, Heated IntraThoracic Chemotherapy. This is for patients who have disease spreading in the pulmonary area. 

Types of cancers that can be treated by HIPEC: 

-          LAMN (Low-grade appendiceal mucinous neoplasm)

-          Appendiceal

-          Colon

-          Rectal

-          Gastric

-          Stomach

-          Pancreatic

-          Breast

-          Mesothelioma

-          Ovarian

Innovative Technologies at the Forefront

Leading-edge cancer treatments like proton beam therapy, brachytherapy, genetic counseling and dietetics are all offered within the OSF Cancer Institute, providing patients with a one-stop-shop during their cancer journey.  

Proton therapy

Proton therapy was first offered on April 1, 2024.

"Proton therapy lets us offer radiation therapy to patients that maybe wouldn't have been able to tolerate side effects due to tumor location, or factors such as prior radiation treatment to the same area," says Tom Cox, the vice president of operations at OSF Cancer Institute. " This is possible because protons stop after passing through a tumor, eliminating the radiation effects on tissue often treated incidentally to photon (X-ray) therapy. The OSF Cancer Institute is on track to have treated 180 patients by April 1, 2025 – which far exceeded the original first-year target of 130 patients.

Brachytherapy

The brachytherapy suite offers a more patient-friendly way for mostly prostate and gynecological (cervical, endometrial) cancer patients to receive treatment. This option involves placement of applicators or needles directly into tumors so that very controlled, effective radiation can be delivered in discrete volumes. Since the radiation is delivered from within the tumor, there is a dramatic reduction of the dose to normal tissue, even those near the tumor itself. The dose is delivered with high-dose rate techniques so the therapy is delivered in just a few minutes time.

"Being able to bring the introduction of the applicators into the body, the treatment planning CT and the treatment all in one room, has created a much better experience. We're having some really good outcomes there, and we think we can expand what we're able to do there,” Cox says.

Intuitive Ion robot 

The OSF Cancer Institute’s pulmonology team offers state-of-the-art diagnostic tools and treatments, including minimally invasive, robotic surgeries and robotic assistive bronchoscopy. This includes the Intuitive Ion Robot, which allows care teams to get early answers and advance care for lung cancer patients.

"We're going to leverage the ability of an ion robot in the interventional pulmonary lab to really upend how we do the front end of lung cancer care," Cox says. "That robot is going to enable us to biopsy smaller lesions. It has fewer side effects than when you're getting a lung biopsy that's CT-guided. You can also do a staged EBUS (endobronchial ultrasound) exam, so you can diagnosis and stage at the same time."

Rachael Davis, MD, a pulmonologist at OSF Cancer Institute, and her team have been using the ion robot weekly. Dr. Davis and her team are training more providers, and by this summer they’re expecting to quadruple – or more – how often it’s used. 

HIPEC procedures

Hyperthermic intraperitoneal chemotherapy (HIPEC) surgeries are now offered at the OSF Cancer Institute. Tamara Floyd, MD, a surgical oncologist with OSF performs the open surgery and removes tumors from the abdomen. In the HIPEC procedure, heated chemotherapy is circulated through the body for a period of time. The first case went extremely well, and Dr. Floyd is planning her second case for mid-March. 

In addition to treatment options, the OSF Cancer Institute is increasing cancer supportive services in the Peoria region as well.

• Cancer navigation - 13% increase (Specially trained OSF Mission Partners walking you through the process of cancer care) 
• Dietetics - 64% increase
• Palliative medicine - 213% increase (Helps control symptoms, augments treatment from physicians) 
• Genetic counseling - 20% increase

Nutrition journey during cancer

Part of the dietary benefits OSF Cancer Institute offers is in the CEFCU Teaching Kitchen. Oncology dietitians work with patients on recipes to cook and are there with them step-by-step during their cancer journeys. Cox says 50% of people who come in for cancer treatment have dietary risks, while 80% of those people suffer malnutrition during treatment. Having a trained, professional dietary team walking alongside you helps fight those negative complications.

OSF Cancer Institute Culture

Cox credits the Institute’s first-year success to the culture of those who work there. The goal, he says, is to offer cancer support services across the entire spectrum of life. 

"The Mission Partners that work in this building have completely bought in to the idea that we all are advocates for cancer patients. We're always asking patients what they need, to see if we can help them," Cox says. "If we hear there's an issue with travel, or they're having trouble keeping food down, or if their children are not coping very well (with a loved one's cancer diagnosis), we know there are resources in the building, and we try very hard to line up those resources. You can feel it when you walk through the building."

Support services after cancer treatment 

"We can get you with a nurse, an exercise specialist and a dietitian to get back to your best life after cancer. Maybe you like to run a lot and ran half marathons, and you think you'll never be able to do it again. We have rehab and exercise specialists here and nutritionists. Who says you can't do that again? We're going to work with you to see you can get to the life after cancer you want to get to,” Cox says.

Services and medical professionals continue to grow

Building off the first year of OSF Cancer Institute, the administrative team continues to hire world-class medical professionals to offer cancer care in Peoria. A breast surgeon was recently brought onto the team, and a colorectal surgeon will be starting soon.

Additionally, the fourth floor of the building will be built out soon. Cox says this will give much-needed space for the surgical oncology and medical research teams. Research-focused medical oncologists are currently being recruited as well.

Leaving OSF Cancer Institute healthier, and more aware

Patients who leave OSF Cancer Institute don't just leave the building as healthier people; their awareness continues and will benefit other people. Cox admits a cancer diagnosis is not an easy thing to go through, and that the support from the OSF care team doesn’t stop when you walk out the door.

Grateful for community support

Cox says he’s been humbled throughout the years of working in oncology by the incredible commitment of the community and region to the OSF Cancer Institute.

"It is overwhelming to me, the philanthropic spirit of our community and extended community," Cox says. "I take that as, they've made a big commitment to us, and we're making a big commitment back. We're going to bring things to central Illinois that have not been here before. We are going to support you and your family members throughout your life and keep you as healthy, relative to cancer, as we possibly can."

Looking to the future

Cox says the OSF Cancer Institute is looking to bring more pediatric cancer support services to the building, the work collaboratively alongside the adult services.

The team is creating both a lung lesion clinic and a lung multidisciplinary clinic, which aims to reduce the time from finding a cancerous lesion to treatment. The lesion clinic is expected to open in late spring.

The OSF Cancer Institute intake team has been created with oncology nurses who will answer patients’ questions on the very same day, to see if services are right for you.

Cox adds that OSF is planning to put together an early detection hotline as a resource for the community to know if or when they should be screened for cancer.

If you’re looking for more reasons to switch from cocktails to mocktails, the American Association for Cancer Research (AACR)’s newest study may encourage you to embrace sobriety.

The AACR published its 2024 Cancer Progress Report, showcasing that excessive alcohol use increases an individual’s risk of developing six types of cancer.

-          Certain types of head and neck cancer

-          Esophageal squamous cell carcinoma

-          Breast cancer

-          Colorectal cancer

-          Liver cancer

-          Stomach cancers

The study goes on to say that in 2019, 5.4% of cancers were attributed to alcohol consumption. The AACR’s research suggests that by drinking less, or not at all, it can decrease your risk of getting the above-mentioned cancers by 8% and lessen the risk of all cancers by 4%.

Jeanna Rich is an oncology registered dietitian with OSF Cancer Support Services. She says that part of the reason excessive alcohol can affect so many different parts of the body, is because alcohol touches tissue inside the body at most of these places.

"All alcohol contains ethanol, so one alcohol beverage is not safer than the other because they all contain that ethanol component. That can essentially damage or oxidize healthy cells and create DNA damage,” Rich says. “In regard to breast cancer, alcohol can actually increase the levels of estrogen in our body, it can lead to excessive calorie intake, which can lead to obesity." 

Rich says the increase in estrogen is what increases the risk of breast cancer.

Heavy drinking can lead to poor sleep, malnutrition

“Sleep is essential,” Rich says, noting that late nights drinking oftentimes leads to a poor night’s sleep.

“People who are choosing to drink a large amount of alcohol are not eating or drinking other nourishing items, so then they're deficient in other healthy nutrients," Rich adds. 

From cocktails to mocktails

"Why do people drink? Sometimes it's a social factor, sometimes it's for relaxation like going out to dinner with friends and having a glass of wine," Rich says, adding it’s becoming more common to have mocktails on menus at restaurants. “The sober lifestyle trend is becoming very popular. Especially with the New Year coming up, people like to stay sober for a month and see how your body feels, it does make a difference." 

Rich says other than being trendy and fun, if you make them right, mocktails can have beneficial nutrients.

The National Foundation for Cancer Research (NFCR) has year-round and holiday-themed mocktail recipes here. The NFCR reports that most Americans double their alcohol intake between Thanksgiving and Christmas.

"Some can even include cancer-fighting nutrients like cranberries, teas and mints. So, taking that risk factor away, not only takes away the damage that's going to cause your body, but then it provides you with a cancer-fighting nutritional component that's going to enhance your overall health,” Rich says.

Avoid alcohol completely during cancer treatment

On a cancer journey, it’s important to discuss alcohol with your medical team. Rich says it’s imperative to completely avoid alcohol if you’re under treatment.

"Alcohol needs to be detoxed through our liver. Our liver will choose to focus on alcohol first, versus doing other jobs," Rich says. “We are essentially robbing our body of using our cancer treatment and using nutrition to help keep our bodies fighting that cancer. The overall message is to not drink alcohol during cancer treatment and have that conversation with your health care provider or dietitian, to make sure you understand why you're avoiding alcohol.”
