A new study that looked at nearly two million people found vegetarians had a lower risk of pancreatic, prostate, breast, kidney, and blood cancer.<\/p>\n
However, data also showed that vegetarians had a higher risk of esophageal cancer and vegans had a higher risk of colorectal cancer.<\/p>\n
Experts say that eating whole vegetables can be good for you as they\u2019re rich in fiber, vitamins, and minerals\u2014but stress that diet isn\u2019t the only way to lower your risk of cancer.<\/p>\n
There are so many reasons why someone might develop cancer, but research suggests that up to half<\/a> of cases can be prevented through a variety of factors. These include things you can change yourself (quitting smoking, reducing alcohol consumption, and maintaining regular physical activity) as well as more environmental factors (pollution, occupational carcinogens, and radiation) that you might have less control over.<\/p>\n With that, it\u2019s fair to assume that being vegetarian or vegan might also lower your risk of cancer. After all, what could be healthier than a diet full of highly nutritious vegetables? And while earlier studies<\/a> have shown a link between plant-based diets and lower cancer risk, the latest research<\/a> says things are a bit more complicated. The new report says that while following a plant-based diet may lower your risk of many cancers, it won\u2019t necessarily reduce your risk of all of them.<\/p>\n \u201cI hear questions about this all the time in my cancer clinic,\u201d says Anton Bilchik<\/a>, MD, PhD, chief of medicine and director of the Gastrointestinal and Hepatobiliary Program at Providence Saint John\u2019s Cancer Institute in Santa Monica, CA. \u201cWhen a patient is diagnosed, they may say, \u2018I don\u2019t understand why I got cancer because I\u2019m vegan or vegetarian,\u2019 thinking those diets are going to prevent cancer.\u201d And while those diets can certainly be associated with less risk of adverse health outcomes, it’s not a foolproof way of avoiding cancer.<\/p>\n Here\u2019s what the latest study found about what following a plant-based diet can\u2014and can\u2019t\u2014do for your cancer risk.<\/p>\n Meet the experts: Carrie Daniel<\/a>, PhD, MPH, professor of epidemiology at The University of Texas MD Anderson Cancer Center; Sylvia Crowder,<\/a> PhD, health outcomes and behavior researcher at Moffitt Cancer Center; Anton Bilchik<\/a>, MD, PhD, chief of medicine and director of the Gastrointestinal and Hepatobiliary Program at Providence Saint John\u2019s Cancer Institute in Santa Monica, California<\/p>\n What did the study find?<\/p>\n The study, which was published in the British Journal of Cancer,<\/a> analyzed data from more than 1.8 million people who were followed for a median of 16 years. The researchers specifically looked at the diets people followed\u2014including meat-eaters, poultry eaters, pescatarians, vegetarians, and vegans\u2014along with any cancer diagnoses they may have received during the study period.<\/p>\n After crunching the data, they discovered that people who followed a vegetarian diet had a 21 percent lower risk of pancreatic cancer, a 12 percent lower risk of prostate cancer, and a 9 percent lower risk of breast cancer compared to those who ate meat. They also had impressively lower risks of developing less common cancers, like a 28 percent lower risk of kidney cancer and 31 percent lower risk of multiple myeloma, a rare blood cancer.<\/p>\n But researchers also found that vegetarians had almost double the risk of squamous cell carcinoma of the esophagus, and that vegans had a nearly 40 percent higher risk of colorectal cancer compared to meat eaters.<\/p>\n Should you switch to a plant-based diet to lower your risk of cancer?<\/p>\n This is tricky. A large body of research suggests that eating a plant-heavy diet is best for lowering your risk of cancer. But organizations like the American Cancer Society<\/a> (ACS) don\u2019t recommend avoiding meat entirely. Instead, the ACS suggests following a \u201chealthy diet\u201d that includes lots of fruits and vegetables, whole grains, lean protein sources, and low-fat dairy products.<\/p>\n In general, there\u2019s a lot to love about diets that are heavy in plants, says Carrie Daniel<\/a>, PhD, MPH, professor of epidemiology at The University of Texas MD Anderson Cancer Center. These diets tend to be rich in fiber, vitamins, minerals, and bioactive compounds that make up a balanced, healthy diet, she says. Higher fiber intake (around 30 grams per day for adults) supports gut health, while plant compounds help to tamp down inflammation in the body, she adds.<\/p>\n There’s also a matter of what a plant-based diet leaves out. \u201cDiets that emphasize plants also often replace processed or high-fat animal foods, which may further improve overall health patterns,” Daniel explains. These diets also tend to be lower in saturated fat and more nutrient-dense, says Sylvia Crowder,<\/a> PhD, health outcomes and behavior researcher at Moffitt Cancer Center. That can help with weight management, which is an important element in cancer prevention, she explains.<\/p>\n Why would being vegetarian or vegan be associated with a higher risk of other types of cancer?<\/p>\n There are a few theories. Researchers suggested in the paper that vegetarians may be low in important nutrients like B vitamins that could be protective against cancer, while vegans may also struggle with low intakes of calcium and other nutrients that could be protective against certain forms of cancer.<\/p>\n \u201cThe suggestion here is that by not getting adequate minerals or vitamins, that in itself may have a deleterious effect,\u201d Bilchik explains.<\/p>\n Other lifestyle choices can also impact risk beyond diet, Bilchik adds. “If a vegan person doesn’t exercise and is obese, there may be other reasons why they developed cancer.\u201d<\/p>\n It’s also possible someone might follow a vegetarian or vegan diet and still run into other dietary risk factors for cancer, such as eating too many ultra-processed foods<\/a>. In recent years, some ultra-processed meat substitutes have become a popular and convenient way<\/a> for many vegans to adhere to their diet.<\/p>\n All that said, this is one observational study\u2014meaning the researchers didn\u2019t prove that eating a vegetarian or vegan diet raised or lowered the risk of certain cancers. They simply found a link.<\/p>\n The takeaway<\/p>\n \u201cThe most reliable takeaway is that a diet rich in whole plant foods, vegetables, fruits, legumes, whole grains, nuts, and seeds appears beneficial, whether or not someone eliminates meat entirely,\u201d Crowder says. That, plus ensuring you’re getting the necessary vitamins and minerals for a balanced diet and following healthy lifestyle choices in areas beyond diet, sets you up for the best odds.<\/p>\n You Might Also Like<\/p>\n","protected":false},"excerpt":{"rendered":"What Docs Want You to Know About Vegetarian Diets and Cancer Risk Tanja Ivanova – Getty Images “Hearst…\n","protected":false},"author":2,"featured_media":509743,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[34],"tags":[97,52275,32809,88470,167748,7431,231364],"class_list":["post-509742","post","type-post","status-publish","format-standard","has-post-thumbnail","category-health","tag-health","tag-health-outcomes","tag-healthy-diet","tag-moffitt-cancer-center","tag-plant-based-diets","tag-vegan","tag-vegetarians"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/509742","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/comments?post=509742"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/509742\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media\/509743"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media?parent=509742"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/categories?post=509742"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/tags?post=509742"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
