Diet's impact on cancer risk and recuperation: Does what you eat influence your odds and healing process?
In the fight against cancer, diet plays a significant role. Recent research has identified certain foods linked to an increased risk of cancer and others considered cancer-fighting.
Processed red meats, such as bacon, sausages, and hot dogs, are classified by the World Health Organisation as Group 1 carcinogens, with strong evidence linking them to colorectal cancer. These foods contain nitrates and preservatives that can damage gut cells and promote cancerous changes.
Ultra-processed foods (UPFs) and fast foods, including ready-made meals and snacks, have been associated with increased overall cancer risk, although some studies show mixed results. Sugary beverages, particularly soft drinks and fruit juices, promote chronic inflammation and are linked to higher risks of obesity-related cancers such as breast, pancreatic, and colon cancers.
Refined sugars and free sugars, found in sweets, desserts, and sugary drinks, are associated with elevated risks of certain cancers including lung, kidney, and non-Hodgkin lymphoma. Deep-fried foods, especially when oils are reused, lead to acrylamide formation, a compound known to increase cancer risk through inflammation. Trans fats, often found in processed foods, are linked with higher risks of colorectal cancer and other serious diseases.
On the other hand, a diet rich in whole grains, fruits, and vegetables offers cancer protection due to their fiber content, antioxidants, and anti-inflammatory properties. Healthy fats, found in foods like olive oil, nuts, and fish, have protective roles against cancer. Legumes and lentils, plant-based protein sources rich in fiber and antioxidants, offer a healthier alternative to processed meats.
The strongest evidence for cancer prevention lies in a diet rich in fruits and vegetables. Alcohol consumption can increase a person's risk of cancer in certain areas of the body, including the mouth, pharynx (throat), larynx (voice box), liver, esophagus, breast, colorectum. Consuming more than 18 ounces, or three portions, of red meat per week increases a person's risk of developing colorectal cancer.
Regularly eating any amount of processed meat increases the risk of stomach cancer and colorectal cancer, according to the American Institute for Cancer Research. Excess weight may cause certain cancers due to reasons such as hormonal imbalances, inflammation, and increased insulin levels.
Many of the foods on the list, such as apples, beans and peas, blackberries, blueberries, carrots, chili peppers, cranberries, dark green leafy vegetables, flaxseeds, garlic, grapefruit, grapes, raspberries, teas, walnuts, whole grains, and winter squash, are rich in fiber, which is essential for healthy digestion and may help prevent colon cancer.
In the United States, approximately 100,000 people have links to cancer that are associated with excess weight, physical inactivity, poor nutrition, or excessive alcohol consumption. Being overweight or obese may increase the risk of some cancer, including breast, colorectal, endometrial, esophageal, gallbladder, kidney, pancreatic, prostate, cervix, and ovarian cancer.
A doctor can help a person determine a healthy weight for them and provide guidance on weight loss if necessary. An assessment may start with a body mass index (BMI) calculation and waist measurements. Reducing consumption of processed meats, sugary drinks, ultra-processed and deep-fried foods while increasing intake of whole grains, fruits, vegetables, legumes, and healthy fats can lower cancer risk and support overall health.

- Chronic diseases such as chronic kidney disease, COPD, type-2 diabetes, and neurological disorders like Alzheimer's disease, multiple sclerosis, migraine, rheumatoid arthritis, and other autoimmune disorders may also benefit from a healthy diet.
- Diet is essential for maintaining cardiovascular health, eye health, hearing, and skin conditions, among other aspects of health and wellness.
- Regular exercise, fitness, and physical activity, along with a healthy diet, contribute significantly to overall health and well-being.
- Climate change and environmental science have a significant impact on food production and nutrition, making sustainable living through practices like gardening crucial.
- Financial management, such as budgeting, saving, debt management, wealth management, personal finance, and even investing in gadgets like smartphones, can help maintain a healthy lifestyle.
- Smart home devices, such as wearables, can monitor and support healthy living by tracking fitness, sleep patterns, and dietary habits.
- Technology, including artificial intelligence, data and cloud computing, and interior design, can also contribute to a more health-conscious and sustainable lifestyle.
- Lifestyle choices, from outdoor living and recreational activities to following fashion and beauty trends, should be made with health benefits in mind.
