Healthy Eating Linked to Better Heart Health After Cancer

A study of more than 8,700 cancer survivors found that several eating patterns were associated with a lower risk of heart disease over 12 years.

Colorectal Cancer Risk Varies by Processed Food Type

A study of more than 460,000 Americans found no overall association with ultraprocessed food intake, but some food types were associated with higher or lower cancer incidence.

Sugar May Worsen Antibiotic-Related Gut Disruption

In stem cell transplant patients, eating more sugar-rich foods while taking broad-spectrum antibiotics was linked to greater disruption of the gut microbiome.

Diet and Gut Bacteria May Shape Cancer Immunotherapy Response

A mouse study suggests diet may influence how well some cancer treatments work by changing the gut microbiome, but the findings are not a reason to adopt a high-fat diet.

Vitamin C Trial Finds an Intriguing Signal in Early Blood Disorders

A phase 2 trial found no effect on its main measure of disease progression, but fewer serious health events and an unexpected survival difference warrant more study.

Eating Less Appeared to Slow Some Signs of Cellular Aging in Mice

Mice eating 30% fewer calories accumulated fewer changes in their DNA as they aged, offering a new clue about why calorie restriction has been linked to longer life in animals.

Dietary Fat May Matter After Prostate Cancer

A long-term study found that men who ate more saturated fat after diagnosis had a higher risk of death, while some unsaturated and plant-based fats were linked to better survival.

Does Dairy Really Raise Prostate Cancer Risk?

Some studies have linked higher dairy intake with a modest increase in prostate cancer risk, but the evidence does not show that dairy causes the disease or that men need to avoid it entirely.

Antioxidant-Rich Diets Were Linked to Less Cervical Cancer

A new study found an association, but it cannot show that eating more antioxidant-rich foods prevents cervical cancer.

Weight Loss May Explain a Colorectal Cancer Paradox

A study suggests weight lost before diagnosis may make higher BMI appear protective.

Daily Sugary Drinks Linked to Higher Stomach Cancer Risk

A long-running U.S. study found an association between daily sugary drink intake and stomach cancer, but the cancer was uncommon and the study cannot prove the drinks were responsible.

Ketogenic Diet Accelerated Small Intestinal Tumors in Mice

A laboratory study found that a high-fat, very-low-carbohydrate diet affected neighboring parts of the digestive tract differently, promoting tumors in the small intestine while suppressing them in the colon.

Fasting Changed Gut Bacteria, Intestinal Repair in Mice After Radiation

A preclinical study identified a possible pathway linking short-term fasting, the gut microbiome and intestinal regeneration, but it does not show that cancer patients should fast before treatment.

Alcohol May Raise Pancreatic Cancer Risk

A new meta-analysis strengthens evidence linking alcohol intake to pancreatic cancer, especially at higher levels of daily drinking.

Sugary Drinks Were Linked to Higher Risk of Two Liver Cancer Types

A pooled analysis of more than 1.5 million adults found that each additional sugar-sweetened drink per day was associated with higher risks of two liver cancer subtypes, although the study does not prove cause and effect.

Moderate Drinking May Carry More Risk Than Many People Realize

A new modeling study found no overall health benefit from drinking, even at low levels, and estimated that the risk of alcohol-related harm increases as consumption rises.

GLP-1-Based Medications Linked to Lower Risk of Obesity-Related Cancers

A large observational study found fewer cancer diagnoses among adults with obesity who were prescribed semaglutide or tirzepatide, but it does not prove the medications prevent cancer.

Alcohol Raises Cancer Risk Even at Low Levels, Analysis Finds

A global analysis found clear links between alcohol and cancer and liver disease, while the evidence for some heart, metabolic and brain conditions was more complicated.

Low Vitamin D Tied to More Pain After Breast Cancer Surgery

A prospective observational study found vitamin D deficiency was associated with more moderate postoperative pain and greater opioid use, but it cannot prove supplements would reduce pain.

What Vitamin C May Do When Nitrates and Nitrites Reach the Gut

A mathematical modeling study suggests vitamin C may reduce certain cancer-linked chemical reactions during digestion, but it does not prove that supplements prevent cancer.

Cutting Back on Alcohol May Reverse Some Health Risks

A new review finds alcohol contributes to a wide range of diseases and injuries, but some risks may fall when people reduce or stop drinking.

Red Meat Helped Shape Human Diets. Modern Eating Changed the Equation

A new review traces red meat’s complicated role in human evolution, health and disease, arguing that context matters as much as the food itself.

Could Updated Alcohol Warning Labels Make People Think Twice?

A national survey experiment suggests that redesigned alcohol warnings, especially those highlighting cancer risk, were perceived as more effective than current U.S. labels at encouraging people to consider drinking less.

Why Some Cancer Treatments Can Make Food Taste Off

New research suggests certain drugs may change the balance of cells inside taste buds, altering how flavors are perceived.

Doctors Group Pushes for Cancer Warning Labels on Processed Meat

A new legal petition calls for labels on foods like bacon and hot dogs, raising questions about what the science actually shows.
