Modified Japanese diet shows promise for lowering blood pressure, study finds

A study of 12,213 Japanese workers found no link between hypertension and the traditional Japanese diet, but a modified version emphasizing whole grains, fruits, and dairy showed a potential protective effect. The findings highlight how modernizing traditional diets with nutrient-rich foods may combat high blood pressure.

Low vitamin D levels damage erectile health via superoxide surge, study finds

Vitamin D deficiency directly causes erectile dysfunction by increasing superoxide and reducing protective SLPI levels, as shown in human tissue and animal models. This breakthrough reveals why low vitamin D may lead to poor sexual health and resistance to standard ED treatments.

New study examines how obesity alters brain's reward circuits

Obesity is on the rise. Among U.S. adults aged 20 or older, 4 in 10 met the criteria for obesity in the most recent National Health and Nutrition Examination Survey, up from roughly 3 in 10 two decades earlier.

Mid afternoon inhaler use may improve nighttime asthma control

A single daily preventer dose of inhaled corticosteroid (beclomethasone), taken mid afternoon, may be the best timing for effective asthma control as it suppresses the usual nocturnal worsening of symptoms more effectively than dosing regimens at other times of the day, suggest the results of a small clinical trial published in the journal Thorax.

EAT-Lancet planetary diet shows no dementia risk, may protect against Alzheimer’s

In a large Swedish study, researchers found that the environmentally sustainable EAT-Lancet diet does not increase dementia risk and may lower the risk of Alzheimer’s and all-cause dementia, particularly in people without the APOE ε4 gene. The findings support the integration of sustainable diets into dementia prevention strategies.

Peanuts pack a punch for youth: study finds cellular benefits

Daily consumption of skin-roasted peanuts for six months led to a modest but significant increase in telomere length among young, healthy adults, while peanut butter did not show this effect.

Study reveals CT scan overuse could account for 1 in 20 new US cancers

A new study projects that CT scans performed in the US in 2023 could cause around 103,000 future cancers, potentially accounting for 5% of all new cancer diagnoses. Researchers highlight that while individual risks are small, the population impact of unnecessary or high-dose CT imaging is significant.

Study reveals a novel link between body fat and anxiety

In a groundbreaking study, researchers at McMaster University have revealed a novel link between body fat (adipose tissue) and anxiety, shedding light on the intricate relationship between metabolism and mental health.

Discovery of special dendritic cells sheds light on food allergy prevention

The immune system must be able to quickly attack invaders like viruses, while also ignoring harmless stimuli, or allergies can result. Immune cells are known to ignore or "tolerate" molecules found on the body's own healthy cells, for instance, as well as nonthreatening substances from outside the body like food.

Inherited genetic variants play crucial role in cancer development and behavior

A new multicenter study by researchers at the Icahn School of Medicine at Mount Sinai, in collaboration with the National Cancer Institute-funded Clinical Proteomic Tumor Analysis Consortium (CPTAC) and colleagues around the world, has discovered that the genes we are born with-known as germline genetic variants-play a powerful, underappreciated role in how cancer develops and behaves.

Digital lifestyle program cuts diabetes risk by 46% in prediabetics, study of 130k+ adults reveals

A large study of 133,764 adults found that a voluntary digital lifestyle program reduced 10-year diabetes risk by 45.6% in prediabetics and doubled remission rates in diabetics, with significant improvements in triglycerides, insulin resistance, and inflammatory markers like hs-CRP.

Lithium shifts circadian rhythms early in bipolar disorder and may offer clues to treatment response

A randomized controlled trial shows that lithium treatment in bipolar disorder patients reduces daytime activity, advances its onset time, and increases volatility in circadian rest-activity patterns. These changes appear early and independently of mood, offering promise as early biomarkers of treatment response.

Blood test detects Parkinson’s years before symptoms appear using RNA markers

A new study identifies a blood-based biomarker that detects pre-symptomatic Parkinson’s disease by measuring the ratio of specific nuclear and mitochondrial transfer RNA fragments. The test outperforms standard clinical tools and may also reflect disease mechanisms related to impaired protein synthesis.
