Want to cut cancer risk by nearly a quarter? Researchers say this diet is the key

A growing number of researches indicate that consuming more plant-based foods could crucially play a significant role in minimizing cancer risk. A new paper published in the American Journal of Clinical Nutrition supports this evidence, indicating that vegetarians and vegans may have meaningful protection from several cancers, including less common types.

While past research has mainly concentrated on common cancers such as breast, colorectal, and prostate cancer, this study focused to go further. To bridge this information gap, researchers examined whether vegetarian diets will offer protection against a variety of cancer types, not just the more common ones but also the rare types. The study experimented whether vegetarian diets, compared to nonvegetarian diets, could have protective benefits for rarer cancers as well.

The Adventist Health Study-2

The research team drew findings from the Adventist Health Study-2 (AHS-2) cohort, a large scale project that involves participants across the United States and Canada between 2002 and 2007. The participants were volunteer of the Seventh-day Adventist Church, most of them already follow vegetarian or plant-based consumption. This provided researchers a unique opportunity to analyze dietary patterns in a group.


A total of 95,863 people primarily took part, but after excluding those with preexisting cancers, incomplete information, or residency outside covered cancer registries, the final analysis involved 79,468 volunteera. Each volunteer finished a detailed mailed questionnaire, which involved a validated food survey to trace consuming habits from last year. To make sure of accuracy, researchers supplemented this with 24-hour dietary recalls from a subgroup of 1,100 participants and tested dietary biomarkers.

Minly, the study accounted for many elements that could influence cancer risk such as age, sex, race, and other lifestyle elements enabling them to strengthen the accuracy of the results.

Results: Who Benefited the Most

Overall, vegetarian diets were associated with lower cancer risk, but the degree of advantage varied depending on the specific diet type.

• Vegans with a 24% lower cancer risk compared to nonvegetarians.
  
• Lacto-ovo vegetarians (those who consume dairy and eggs) had a 9% lower risk.
  
• Pesco-vegetarians (those who include fish and avoid meat) saw an 11% reduction.
  

When looking at medium-frequency cancers, vegans once again had the strongest protection, with a 23% reduction in risk, followed by lacto-ovo vegetarians (18%) and pesco-vegetarians (13%).

For certain types of cancers, the differences were especially striking:

• Younger vegans (under age 65) had a 43% lower risk of prostate cancer, though this advantage was not seen in older vegans.
  
• Younger vegans also had a 31% lower risk of breast cancer, with older vegans indicating a similar but less precise trends.
  
• For lymphomas, older vegans had a 56% lower risk, while younger vegans did not indicate a major difference.
  

Transitioning to a Plant-Based Lifestyle

For those interested in adopting a vegetarian or vegan diet, planning is a key factor.

• Protein can be received from beans, lentils, chickpeas, tofu, and whole grains.
  
• Iron from plants should be combined with vitamin C-rich foods, like citrus or peppers, to enhance absorption.
  
• Vitamin B12, vitamin D, and omega-3s might need supplementation or fortified foods for those avoiding out all animal based products.

Health professionals highly recommend a gradual transition rather than a switch overnight . This approach benefits the digestive system to adapt to higher fiber intake while making it easier to discover new meals and build sustainable habits.
