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

Columbia scientists develop world's first prototype ‘Universal Antiviral'
Scientists at Columbia University are developing a universal antiviral. This treatment aims to protect against many viruses, including influenza and COVID-19. The therapy is inspired by a rare genetic mutation. It uses mRNA technology to produce antiviral proteins. Tests on mice and hamsters show reduced viral replication. This offers short-term protection during outbreaks. Tired of too many ads? Remove Ads Rare disorder reveals hidden defense Tired of too many ads? Remove Ads Turning biology into therapy A temporary but powerful shield Challenges ahead A team of Columbia University scientists says it may be closer than ever to creating a universal antiviral , a treatment designed to temporarily shield people against a wide range of viruses, from influenza to experimental therapy, detailed August 13 in Science Translational Medicine , is inspired by a rare genetic mutation that gives a small number of people an extraordinary ability: resistance to nearly all viral infections About 15 years ago, Columbia immunologist Dr. Dusan Bogunovic began studying patients with a rare immune condition known as ISG15 deficiency . Though these individuals were more prone to certain bacterial infections, they seemed to shrug off viral illnesses without ever developing study revealed that the mutation caused a constant, low-level state of immune activation, a kind of background inflammation that was highly effective at blocking viruses. 'The type of inflammation they had was antiviral,' Bogunovic recalled in a Columbia University of reproducing the harmful aspects of ISG15 deficiency, Bogunovic's team identified 10 specific proteins responsible for most of the antiviral protection. They then engineered an mRNA-based therapy, similar in design to COVID-19 vaccines, that prompts cells to briefly produce those through the nose into the lungs of mice and hamsters, the treatment significantly reduced replication of both influenza and SARS-CoV-2, the virus that causes COVID-19. In cell culture tests, the therapy appeared to resist a wide variety of a vaccine, which builds lasting immunity to a specific pathogen, this treatment provides only short-term protection, estimated at three to four days in animals. Researchers say that could make it particularly valuable at the beginning of outbreaks, giving first responders, health workers, and high-risk populations an immediate layer of defense while vaccines are still in therapy also does not interfere with long-term immunity, meaning patients could still develop protective memory after infection or concept remains in early stages. Researchers say improving the delivery system, ensuring enough of the proteins are produced in the right tissues, is the biggest hurdle before moving into human trials. More work is also needed to determine how long protection lasts and how safe repeated dosing might experts say the findings are promising. By activating the body's own antiviral machinery, the therapy could offer a virus-agnostic defense that works even when the identity of a new pathogen is unknown.

Russia launches animals into space: Here's the purpose behind the mission
Russia has a longstanding history of launching animals into orbit, a practice that began early back to the Soviet space program. Since the 1950s, these missions showcased technological capabilities and provided essential insights into how living beings react to the extreme conditions of space. Building on this history, Russia is preparing to launch the Bion-M No. 2 biosatellite on August 20, 2025, using a Soyuz-2.1b rocket from the Baikonur Cosmodrome in Kazakhstan. Often referred to as a modern 'Noah's Ark,' this mission will carry 75 mice, more than 1,000 fruit flies, plant seeds, cell cultures, and microorganisms for a 30-day orbital experiment. The main focus is to examine how prolonged exposure to microgravity and cosmic radiation impacts living organisms, providing important information for future human spaceflight. Innovations Compared to Earlier Missions Following the precedent set by the 2013 Bion-M No. 1 mission, Bion-M No. 2 will follow in a polar orbit inclined at roughly 97 degrees. This flight path exposes the biosatellite to far higher stages of cosmic radiation estimated to be at least ten times more than the earlier mission. These conditions better replicate the environment astronauts face during extended deep-space missions, enabling for more accurate information on the biological effects of space travel. Mice: A Core Focus for Space Medicine Mice play a critical role in the mission due to their genetic resemblance to humans, short lifespans, and heightened sensitivity to radiation. The animals will be organized into three groups: one kept on Earth under normal conditions, a second in a ground-based simulator replicating spacecraft conditions, and a third sent into orbit. This arrangement enables scientists to compare how spaceflight changes biological systems compared to Earth-based controls. Each habitat is equipped with feeding systems, lighting, ventilation, and waste disposal. Sensors and cameras will monitor the mice constantly , and some will carry implanted devices to record physiological changes during the mission. After returning to Earth, researchers will analyze how they adapted to space conditions and how they readjusted to gravity. Live Events Fruit Flies and Other Experimental Subjects Alongside the mice, over 1,000 fruit flies will also travel on the mission. . Their extensively studied biology and quick generational cycles, provide valuable insights into radiation that influence at the genetic and cellular levels. Plant seeds and cell cultures aboard the biosatellite will further inform researchers about how microgravity affects growth and cellular these experiments offer a holistic view of life's response to the conditions of space. Lunar Simulants: Exploring Moon-Like Conditions In a unique addition, the mission will include 16 test tubes of lunar simulants materials made to replicate Moon dust and rocks. Conducted in collaboration with the Vernadsky Institute of Geochemistry and Analytical Chemistry and the Institute of Medical and Biological Problems, focus to observe how lunar-like substances communicate with biological systems in orbit. The insights could guide future lunar exploration and shed light on potential effects on living organisms. FAQs: Q1. What is Bion-M No. 2? A1. A Russian space mission examining how living organisms respond to space conditions. Q2. When will it launch? A2. It will launch on August 20, 2025.
