Dietary habits and physical activity are primary lifestyle factors that have the most evidence demonstrating an impact on cancer risk. Certain foods, minerals, and other parts of a person’s diet have associations with reducing or increasing the risk of cancer. Improvements in lifestyle behaviors to reduce cancer risks include a healthy diet, calorie restriction, and regular physical activity.
Simple lifestyle changes, such as following a healthy diet, could prevent 30–50 of all cancers. Growing evidence points to certain dietary habits increasing or decreasing cancer risk. The 2018 WCRF/AICR Third Expert Report examined the evidence for the American Cancer Society cancer prevention guidelines score, healthy eating index (HEI)-2005, alternative Mediterranean diet, and more.
Your overall diet has a bigger impact on cancer risk than any individual food or ingredients. Experts estimate that at least 42 of newly diagnosed cancer cases in the United States are caused by modifiable lifestyle factors and are potentially preventable. However, 30–50 of all cancer cases can be prevented by following a healthy diet and lifestyle, according to the World Cancer Research Fund.
Bad diet, inactivity, smoking, and drinking alcohol are among the causes of up to 90 percent of cancers, according to a new analysis. Many studies have looked at the possibility that specific dietary components or nutrients are associated with increases or decreases in cancer risk. New research shows that more than 135,000 cases of cancer could be prevented in the UK each year largely through lifestyle changes. Diet and nutrition represent one of the most important factors in the development of cancer, with a correct diet, such as the Mediterranean diet, rich in essential nutrients.

What cancers are affected by diet?
High-fat, low-fiber diets can increase the risk of various cancers, including bowel, lung, prostate, and uterine cancers. Reducing alcohol intake and maintaining a healthy body weight can also reduce the risk of cancer. Eating a variety of nutritious foods, as described in the Australian Guide to Healthy Eating, can also reduce cancer risk. However, there is little evidence that special foods can cure existing cancers.
What percentage of cancers is influenced by diet?
The American Institute for Cancer Research and the World Cancer Research Fund estimate that 30-40% of all cancers can be prevented by appropriate diets, physical activity, and maintaining an appropriate body weight. Obesity, nutrient-sparse foods, low fiber intake, red meat consumption, and an imbalance of omega 3 and omega 6 fats contribute to excess cancer risk. Intake of flax seed, fruits, vegetables, and antioxidants like carotenoids can lower cancer risk.
Protective elements in a cancer prevention diet include selenium, folic acid, vitamin B-12, vitamin D, chlorophyll, and antioxidants like carotenoids. Ascorbic acid has limited benefits orally but could be beneficial intravenously. Supplementary use of oral digestive enzymes and probiotics also has merit as anticancer dietary measures.
A diet compiled according to these guidelines is likely to result in at least a 60-70% decrease in breast, colorectal, and prostate cancers, and even a 40-50% decrease in lung cancer. Such a diet would be conducive to preventing cancer and favoring recovery from cancer.
Research on nutrition and cancer has been reductionist, studying specific foods or nutrients in relation to tumor formation or regression at specific sites in the body. However, this does not provide an overall picture of how to prevent cancer on a dietary level or how to eat when someone already has a cancer and wishes to eat a diet favorable to their recovery.
What percentage of cancer cases does diet play a role in?
A healthy, balanced diet and a focus on nutrition are crucial for cancer prevention, as dietary factors account for about 30% of cancers in Western countries. Food and nutrition are significant factors in disease, as they are broken down and used by cells in the body. Researchers examine foods and their chemicals to determine if they fuel or prevent cancer cell growth. Obesity, which can cause long-term inflammation and increase hormones, is another linked factor to food intake, potentially increasing the risk of certain cancers, such as breast cancer.
What are the odds of getting cancer if you eat healthy?
The body relies on food for its functions and health, and no food or food group can prevent cancer. However, consuming healthy meals rich in vegetables, whole grains, beans, and fruits, along with following basic guidelines, can reduce the risk of cancer and other chronic diseases. To pack a healthy meal, fill at least two-thirds of your plate with vegetables, whole grains, fruits, and beans, along with nuts and seeds.
The remaining third should consist of meat, fish, animal products, or plant-based proteins like tofu. Healthy meals can be tasty and exciting, so consider adding more whole grains, vegetables, fruits, nuts, and seeds to your favorite dishes.
Is there a relationship between diet and cancer?
The connection between cancer and diet is complex, with research suggesting certain foods and nutrients may help prevent or contribute to certain types of cancer. While genetics and environment are uncontrollable factors, less than 30% of a person’s lifetime cancer risk comes from these factors. However, there are some factors that can be controlled, such as diet, which can help reduce cancer risk. Harvard Health Publishing offers access to its archived content, ensuring readers can access the latest reviews or updates on all articles.
What percentage of cancers are preventable?
A study conducted by the American Cancer Society has revealed that 42 out of 165 cancer cases and 45 deaths in the United States are attributable to modifiable risk factors, which could potentially be prevented. The study, based on data from 2014, estimated that lifestyle factors contributed to 26 different cancer types among adults aged 30 and older.
What percentage of cancer is caused by a poor diet?
Poor diet is linked to increased cancer risk and mortality, with higher intakes of red and processed meat and sugar-sweetened beverages (SSBs) and lower intake of whole grains, vegetables, and fruit. The proportion of new cancer cases attributable to suboptimal diet ranges from 4. 2 to 5. 2, resulting in approximately 67, 000 to 80, 000. Disparities in cancer outcomes among racial and ethnic groups and by socioeconomic status are well documented. Wang et al.
Estimate the lifetime health and economic costs of cancer attributable to poor diet among US subpopulations defined by age, sex, race/ethnicity, education, income, and Supplemental Nutrition Assistance Program (SNAP) participation. They projected both direct and indirect effects of poor diet, using publicly available data and modeling techniques.
Using publicly available data and modeling techniques, the authors estimated that the impact of suboptimal intakes of seven dietary factors accounted for 3. 04 million new cancer cases (7. 4) and 1. 74 million cancer deaths (7. 7) among US adults over a lifetime. They also estimated $254 billion in medical costs attributable to poor diet (7. 8 of direct medical costs of 15 diet-related cancers in the United States).
Wang et al.’s contribution is the quantification of disparities in the diet-attributable burden of cancer in subpopulations by cancer type and dietary factor. For example, non-Hispanic Black persons would experience more diet-attributed incident cancers and cancer deaths than non-Hispanic White persons, with a difference of 110 cases and 214 deaths per 100, 000. This disparity applies to all cancers studied, but particularly colorectal cancer, with the highest burden being greatest for low consumption of dairy and whole grains and excess consumption of processed meats and SSBs.
Does eating healthy avoid cancer?
A diet that is generally healthy, combined with regular exercise and a healthy body weight, can significantly reduce the risk of developing cancer. It has been estimated that approximately one in five cases of cancer could be prevented through these methods.
What is the main contributor to cancer?
Cancer is a complex disease caused by a combination of genetic, environmental, and constitutional factors. Childhood cancers have a higher survival rate of around 80 percent over five years, compared to 68 percent in adult cancers. This is due to the child’s increased sensitivity to therapy and ability to tolerate more aggressive treatment. Childhood cancers typically originate in stem cells, which can produce other specialized cells. A sporadic cell change or mutation is usually responsible for childhood cancer.
In adults, epithelial cells, which line the body cavity and cover the surface, become cancerous due to environmental exposure over time. Adult cancers are sometimes referred to as acquired due to this.
Are poor people more likely to get cancer?
The American Cancer Society’s annual “Cancer Facts and Figures 2011” highlights that poverty is a significant contributor to cancer disparities among social groups. People living in poverty lack access to quality healthcare, leading to greater pain and illness. They are more likely to die from cancer than affluent individuals due to their lack of access to quality care and obstacles in providing and using health insurance.
Poverty also leads to other health-related problems, such as a low intake of fresh fruits and vegetables, which is associated with a higher risk of gastro intestinal cancers. Additionally, poor people are more vulnerable to environmental factors inducing human cancers, such as tobacco use, sunlight and ionizing radiation, alcohol consumption, organic and inorganic chemicals, and infectious micro-organisms.
Certain cancer incidence and survival rates are related to socioeconomic circumstances, with lower social classes having higher cancer incidence and poorer survival rates than higher social classes. Occupation, reproductive behavior, and biological agents (Human papilloma-viruses, H. pylori, Hepatitis B, and Hepatitis C) have been shown to be significant mitigating issues for the occurrence of cancer within disparate socioeconomic strata.
Approximately two out of every three cancer deaths are caused by smoking, poor diet, obesity, sedentary lifestyle, or failing to use cancer screening tests. Many of these factors are related to poverty, which is also a barrier to accessing effective cancer therapies.
The social impact of chronic diseases like cancer is another issue that influences each other in a bidirectional manner. There is a growing recognition in international policy making and programing for poverty reduction, with the hope of a more equal distribution of resources and research focused on disease prevention, ultimately reducing poverty and health inequalities among countries.
What percent of cancer is related to lifestyle?
A study in the U. S. found that nearly 40% of all cancer cases and 44 of cancer-related deaths in 2019 were attributed to modifiable risk factors, with cigarette smoking being the most significant risk factor. Lung cancer was the predominant form of cancer attributed to these factors. The study highlights the growing number of cancer cases and mortality linked to modifiable risk factors, suggesting that lifestyle changes such as avoiding smoking, reducing alcohol and red meat consumption, achieving adequate physical activity, and eating a healthy diet can significantly lower the overall cancer burden.

My mom was given 2 months left to live due to stage 4 breast cancer. She is now going strong after 6 months. I completely changed her diet to whole foods and organic if possible. Family also sneaks in bad food for her, but the main thing is she’s not eating processed junk food anymore. I have her on Fenbendazole, high doses of vitamin C IV drip, and Rick Simpson oil (cbd/thc). What a game changer!! She was unable to assist herself to the bathroom, but now that I have her on these protocols, she’s able to go to the bathroom by herself, she has meat in her face now and gained a few pounds!!!!!
Is also the best diet for prevention! Eat your organic G-BOMBS daily. Greens (cruciferous and colorful vegetables) Beans (legumes) Onions (red and raw) Mushrooms (cooked) Berries Seeds (and nuts and spices) Hydrate with 99% pure filtered water 6-8 glasses daily. Daily exercise. Quality 7-8 hours of sleep. Prayers/de stress/gratitude/generosity/forgiveness/love.
Cancer is NOT caused by mutations in our DNA. It’s caused by disruption of the mitochondria in the cytoplasm, which then causes damage to the DNA in the nucleus. Read Dr Thomas Seyfried’s book, “Cancer As A Metabolic Disease”, or look at one of the many Seyfried articles YouTube. This does not make Michael Greger’s dietary advice in this article wrong. Not at all. However, understanding the metabolic theory of cancer, as opposed to the conventional somatic mutation theory of cancer, provides an understanding of WHY Michael Greger’s advice in this article works.
I have a relative with triple negative breast cancer. Her dietician told her to “eat whatever she wants”. I’m surprised that a dietician would give her that advice. Meanwhile, my husband has advanced prostate cancer and has tried to stick to your diet plan as closely as possible, though he’s been leaning towards a more fatty, processed vegan diet lately. He’ll be perusal this. I hope it’ll motivate him to go back to sticking to your diet recommendations more.
If you read the warnings for the chemo drugs, cardiac arrest is one of the potential side effects. Chemo often causes secondary cancers. And it weakens people so much that they suffer falls which happened to a friend of mine. She cracked some ribs, a blood clot formed and traveled to her heart. So she really died of complications of the chemo not the cancer.
Went to doctor’s appointment with my aunt. (Stage 3 triple negative bc. Starting treatment soon) Chemo education nurse told her to eat anything she wanted.” If only ice cream taste’s good to you, eat it”. Another nurse educator advised against eating too many fresh vegetables and fruits “because the same anti oxidants that feed health cells, also feed cancer cells!” I was dumbfounded! Doesn’t always seem to be a good idea to listen to the “professionals”. Do what feels right to you and try to be at peace about it.
Hospitals, doctors offices and schools should be places where good nutrition is taught and provided not places that contribute to disease and obesity. It is crazy the hospitals are feeding people the very food that caused the heart disease, high blood pressure or cancer that they are treating. Every person in the hospital should receive some nutrition education before being released. Every doctor visit should be an opportunity to educate patients about how food choices impacts their health outcomes. The fact that doctors do not get nutrition training as part of their training makes no sense. Medicare and Medicaid should require nutrition education as part of patient care. Focus should be on food choices.
If Ketogenic is not good for cancer patients? Why are so many people able to defeat cancer through fasting and ketogenic/LCHF diet? Then again, the best way to actually find the best diet for cancer patients is to have many subjects following different diets. Once there are enough people with cancer following vegan way, LCHF way, carnivore way, etc.. As a statistician, i will appreciate the resulting data. Which diet actually help more for people with cancer only can be said with actual numbers, not theories.
The statement at :19 implies that “ductal carcinoma of the breast” is not “serious cancer”. That is not accurate. IBreast cancers can develop in the ducts or the lobes and ductal carcinoma is most common. Its “seriousness” is indicated in designation of stages 1-4 which use multiple measures to estimate how much the cancer has invaded other parts of the body, how fast it is growing, what types of receptors are driving growth and what treatments may be helpful. Ductal carcinoma “in situ” has not yet moved beyond the duct in which it formed. In some cases it will never spread but in other cases it will progress to a stage 1-4 cancer. Because of this some people choose not to pursue treatment at this stage, but we do not yet have tests that can tell us which cases will be harmless and which will grow and become invasive killers. Designating DCIS in general as “not serious” ignores differences in tumor size, growth rate and receptor type and takes decision making power away from women, who should be encouraged to make their own decisions to watch-and-wait or treat now with their medical team. In this article, brushing aside all “ductal carcinoma” as not a serious cancer is potentially dangerous and irrelevant to the topic.
A common myth: You can not “starve” a tumor if you avoid sugar. Although cancer metabolism requires more glucose, the cells have also much MUCH more glucose transporter. Sadly you would starve your entire body first before even inhibiting the cancer. Obviously there are other issues with an OVERconsumption of sugar, tho in many critical cancer patient cases we have to keep in mind that its already a blessing if they keep eating the food at all.
Interesting article, but I guess we need a lot more research. During radiation therapy you are currently advised to not take any antioxidant supplements, because they can also protect the cancer from radiation (which is what we normally want antioxidants to do, just for normal tissue ). I was wondering if a diet very rich in antioxidants could be unfavorable during Radiotherapy. Sadly, no studies yet.
The name WFPD alienates a lot of people from considering it regardless because they use the word plants in the name. In a lot of circles that has a negative connotation. In order for people to consider it has a lot to do with there current health condition and there social network, the farther it is from mainstream eating the less likely it becomes for people to consider it regardless of how healthy it might be for them. Some of it has to do with education or what part the country your from etc. I know that sounds strange but people are influenced by the company they keep. So no matter how compelling a diet might be there has to be acceptance and support for people to stick with it. No one wants to be an outcast and people can be cruel so that is a factor. So I think how you market a good thing has to be done in away that is not too over the top and education plays a big part of it as well and why people like Dr. Greger are so important in delivering the message. The more health care practitioners get the word out to there patients the more a WFPD will gain acceptance. Doctors add credibility and a lot of people listen to them when they don’t push pills. We’re only beginning to discover all the benefits WFPD but not everyone has gotten the message yet and those who have my still be reluctant because they don’t have the support network to follow through with it. I have family members who have gotten dramatic benefits that have NAFLD and Type 2 diabetes but they have a hard time sticking to it because they don’t have the support none of their friends, spouses or other family members even know they even have these health issues.
My sister has breast cancer and neck cancer and she has received nutritional information about eating a healthy diet. I’m a vegan, who tries to eat wfpb, and I’ve had many conversations with her about eating more plant based. She says she’d rather be dead than eat like that, I guess that time will come sooner than later for her.
I had all kinds of health and other issues (gastrointestinal, energy level, brain fog) during the 12 years I was vegetarian, vegan, raw food, etc. Over the past 10 years (I’m in my mid-40s), I began eating LOTS of organic grass-fed meats, 15-20 eggs per week (from my own happy free range chickens), and all of my blood work is immaculate. My family has a massive history of heart disease and cholesterol issues. My sister has been a vegetarian for 35 years, and has really high cholesterol (LDLs and triglycerides). My other sister is about the same with health issues, but eats a decent omnivore healthy diet. My dad (in his mid-70s) has been a vegetarian almost 20 years, while on statins, and continues to struggle with high LDL and triglyceride levels. I focus on the quality of my food. I eat lots of fats (even bacon!), and some veggies for most meals. Meat or eggs in almost all meals. I FEEL GREAT, and my health is excellent. All bodies and genetics are a little different. Please don’t think this guy’s recommendations are automatically true for you! Population studies are not individual studies!
That’s not very fair on Vegans, cos you didn’t say anything about the other diets that are worse when eating ‘’Junk products’’. For example the animal based diets you didn’t say they got worse when processed meat etc was eaten. Also precludes the benefits of Wholefood Plant Based/Vegan suitable diets, which as you know is supremely healthy 🌻✊🏽🌎
Dr. Greger is one of my idols and is the reason why I’m eating plant based that. Recently, I heard a criticism about his claim that a WFPB is the only diet ever proven to reverse heart disease. The criticism was that Esselstyn’s paper wasn’t an experiment but a write up about his experiences giving treatment. And the Ornish study has other variables that could be confounding. Thoughts anyone?
I almost died at age 45 after plant-based diet for 30+ years, decided if I’m gonna die, I’m gonna eat whatever I want, so started back on bacon, eggs, grits sausage, steak and all the things “they” said would kill us, within one week started feeling much better and now in my 60’s have hope and taking on each and everyday. hallelujah.
Thank you so much Dr igho, your Utmost Dedication In curing others and your generous heart that you have, I am absolutely Delighted & proud of the results I got after using your meds that boost my testosterone & cured my Erectile Dysfunction after using it by your prescription after a long time living with it. thank you Dr you did well.
Saying whole grains are good for cancer is like saying sugar and carbohydrates are good for cancer. Contradicts itself when saying that obesity is bad for cancer. Whole grains are bad for cancer, period. Also fruits are bad too because of the sugar (fructose). 2 minutes in and Im already doubting if this information is correct
This is poor advice and potentially harmful for cancer patients. Cancer feeds on blood glucose. Eating more grains will increase availability of blood glucose. A clean ketogenic diet is the best for limiting blood glucose, starving cancer, and reducing cellular inflammation which is the primary trigger for cells to become cancerous…combined with B17 it is a very strong approach to healing cancer.
