A new study investigates a compound called theobromine, which is found predominantly in chocolate. Participants with the highest blood levels of this compound had signs that their biological age was advancing more slowly. Although the results are preliminary, experts believe they warrant further exploration.
Reducing caloric intake by 30% for 20 years slowed down indicators of brain aging in a new study of rhesus monkeys. Specifically, calorie reduction appeared to enhance the integrity of the brain’s glial cells and neuronal connectivity. Such a radical reduction in calories in humans is probably not advisable. However, the study does suggest that calorie reduction may play a role in maintaining human brain function optimally for longer.
Insomnia is a disorder characterized by experiencing difficulty falling or staying asleep, or waking up too early. Past studies have linked inadequate sleep to several health conditions, all of which can negatively impact a person’s life expectancy. A new study found that insufficient sleep had a more significant impact on decreased life expectancy than other lifestyle factors, such as diet, physical activity, and social isolation.
A new study investigated the impact of supplementing one’s diet with peanuts on brain health. The researchers conducted the study in older adults and included a control phase and a test phase. During the test phase, the participants ate 2 servings of peanuts daily, and by the end of the study, they saw improvements in both brain vascular function and verbal memory.
Research shows that following either the Mediterranean, DASH, or AHEI diet may lower the risk of developing type 2 diabetes. Studies from 2025 suggest that the DASH diet may be one of the most effective ways to reduce the risk of diabetes complications. Recent research has also found that 3 to 5 cups of coffee per day may be linked to a longer life and a lower risk of type 2 diabetes. Finally, recent evidence shows that a plant compound found in nuts, fruits, and vegetables may help lower the risk of diabetes and heart disease.
In 2024, an estimated 1.4 billion people around the world were living with hypertension. There are several modifiable risk factors that can help a person possibly lower their high blood pressure risk, such as eating a heart-healthy diet. Certain nutrients like potassium and magnesium may help improve a person’s blood pressure. A says that taking a daily multivitamin long-term may help reduce high blood pressure risk and blood pressure overall in older adults following a low-quality diet.
Soybean oil encompasses 57% of all cooking oils used in the United States, and 30% globally. More than 50% of soybean oil is made of an omega-6 fatty acid called linoleic acid. Past studies show that consuming too much soybean oil or omega-6 fatty acids may increase your risk for certain health concerns, such as obesity. A new study sheds light on how soybean oil might contribute to a person’s obesity risk.
By pairing everyday smartphone motion data with established clinical scores, researchers demonstrate a promising path toward accessible, radiation-free screening for early dopamine loss in Parkinson’s disease and related prodromal states.
The lack of a cure for dementia highlights the importance of interventions that can help mitigate risk through modifiable factors. A new study showed that mild or greater hearing loss in midlife was associated with a 71% higher risk of dementia over a 15-year follow-up period. The study also showed that individuals with mild or greater hearing loss were more likely to show deficits in cognitive function and elevated levels of brain imaging markers for dementia. The use of hearing aids helped lower the risk of dementia among individuals with hearing loss, underscoring the importance of early detection and treatment of hearing problems.
New research shows that young Canadians who take pre-workout supplements are more than twice as likely to sleep five hours or less, raising new questions about how workout stimulants may be affecting recovery, mood, and next-day performance.
Long-term exposure to common air pollutants is associated with more advanced coronary artery disease-with notable differences between women and men-according to a large-scale study of more than 11,000 adults being presented today at the annual meeting of the Radiological Society of North America (RSNA).
A large multi-country study identifies the air pollution levels at which the health benefits of regular physical activity start to decline, offering clearer guidance for staying active in areas with rising PM2.5 exposure.
