Popular artificial sweetener may negatively affect cancer immunotherapy

Non-sugar, or artificial, sweeteners are widely used to reduce the energy in sweetened foods and drinks, particularly those marketed as diet, or low or no sugar. However, concerns about their possible health effects include links to gastrointestinal problems, metabolic effects, and even increased cancer risk. Now, a study has found that one of the most widely used artificial sweeteners, sucralose, could adversely affect cancer immunotherapy. The researchers suggest that by changing the gut microbiome, sucralose decreases the effectiveness of immunotherapy for several cancers.

3,000 steps a day at a faster pace may lower cardiovascular risks by 17%

Increasing daily step counts and walking faster may reduce risk of cardiovascular events in people with hypertension, a recent study has found. Walking more than 3,000 steps each day reduced risk of major adverse cardiovascular events by 17%. The benefits of walking also reduced risk of cardiovascular events in people without hypertension.

Free online tool may help calculate biological heart age and disease risk

A person’s “heart age” may not always be the same as their chronological age, which can raise a person’s risk for heart disease. A team of researchers has developed a free online tool to help people calculate their heart age to determine their cardiovascular disease risk. The research team tested the new online tool on thousands of American adults and found most adults have a heart that is several years older than their chronological age.

Study finds turning point when body starts aging rapidly

Past studies show that human aging doesn’t necessarily happen at the same pace throughout our life. There is still much to discover about the aging process, especially when it comes to how it impacts the body’s organs. A new study found that by focusing on aging-related protein changes in the body, there is an acceleration in aging of organs and tissues around the age of 50. And of these proteins, scientists found that expressions of 48 of them linked to diseases increased with age, such as cardiovascular and liver disease.

Are 7,000 steps a day enough to see health benefits?

A lot of people focus on getting 10,000 steps a day for its purported health benefits. A new study says that walking for only 7,000 steps a day can help reduce a person’s risk for heart disease, type 2 diabetes, dementia, cancer, depression, and all-cause mortality. Scientists also discovered that walking around 4,000 steps a day still offers more health benefits than people with very low activity and about 2,000 steps a day.

Lower physical activity may impact your heart health 12 years before disease onset

Several lifestyle changes can help lower the risk for heart disease, including being physically active. A new study found that adults who developed heart disease later in life experienced a decline in their physical activity about 12 years before their cardiovascular event. Scientists also discovered that Black male participants had a more continuous decline in physical activity from young adulthood to middle age, and Black female participants consistently reported the lowest physical activity throughout adulthood, highlighting disparity.

Inflammatory diets, ultra-processed foods may increase Crohn's disease risk

Inflammatory bowel disease (IBD) is a group of chronic conditions that damage the intestines and can cause uncomfortable symptoms. Preventing IBD remains a challenge, and research is underway to minimize this risk. A recent systematic review and meta-analyses identified dietary choices that may affect risk for Crohn’s disease, a major type of IBD. The study saw benefits from a Mediterranean-style diet and increased risk from diets containing inflammatory and ultraprocessed foods.

High amounts of ultra-processed foods may increase lung cancer risk by 41%

High amounts of ultra-processed foods may increase lung cancer risk by 41%

As the proportion of ultra-processed foods (UPFs) in the Western diet increases, concerns are growing about their health effects. Studies have linked UPFs with many health conditions, including obesity, type 2 diabetes, cardiovascular disease, and several types of cancer. Now, a study suggests that high consumption of UPFs could increase a person’s chance of developing lung cancer. While observing a link, the study cannot prove that UPFs cause lung cancer, but highlights a need for further studies.

Lifestyle changes in 4 areas may improve brain health, major US study finds

A program of exercise, nutrition, cognitive and social challenges, and health coaching resulted in improved cognition scores for people at risk of Alzheimer’s disease and related dementias. The two-year trial involved lifestyle changes only, without added medications. Some participants followed the program self-guided, but those receiving the program in a structured format improved more, though all participants’ cognitive scores improved.

Why are colorectal, other GI cancers on the rise in younger people?

Why are colorectal, other GI cancers on the rise in younger people?

Increasing age is the greatest risk factor for all types of cancer, with most cases being diagnosed in people over the age of 60. However, in people under 50, there has been a rapid, worldwide increase in cancers of the digestive system, or gastrointestinal cancers. Although still far less common than in older people, early-onset colorectal cancer is now the leading cause of cancer-related deaths in men, and the second in women, in the United States. The exact cause is unknown, but the authors of a new review published in the British Journal of Surgery suggest that obesity, a Western-style diet, nonalcoholic fatty liver disease, smoking, excessive alcohol use, and even exposure to microplastics, may all be contributing to the rise. Another study, published in Nature Medicine, has further estimated that, without early intervention, as many as 15.6 million gastric cancer cases may occur in the next few decades, most of which, are attributable to infection with a common bacterium, Helicobacter pylori.

GLP-1s may offer better dementia protection than metformin

There were about 589 million adults around the world living with diabetes in 2024, with 90% having type 2 diabetes. Past studies have shown that people who have type 2 diabetes are at a higher risk of developing dementia. A new study has found that when it comes to the neuroprotective abilities of diabetes medications, people taking GLP-1 agonists had a significantly lower cumulative risk of developing dementia, when compared to metformin users.

Olive oil consumption lowers risk of premature death, study suggests

People who consume high amounts of olive oil may lower their risk of premature death overall and from specific causes, including cardiovascular disease, cancer, and neurodegenerative disease, according to a new study led by researchers from Harvard T.H. Chan School of Public Health. The researchers also found that people who consumed olive oil instead of animal fat had a lower risk of total and cause-specific mortality.
