Regular exercise is a known modifiable risk factor for dementia. A new study suggests that weight training may help protect the brains of older adults from dementia. The benefits of weight training were also observed in those already showing signs of mild cognitive impairment. As of 2021, researchers estimate that about globally were living with dementia — a neurological condition that impacts a person's memory and thinking skills. Past studies show there are a number of [...]

Microplastics are common in people's everyday environments, and research is ongoing on microplastics in the human body. Recent study findings revealed that microplastics can be present in the brain's olfactory bulbs. While there is limited research, there could be certain health implications, such as an increased risk for neurodegenerative diseases because of exposure to microplastics. Microplastics permeate the environment, and human beings are frequently exposed to them. [...]

Fasting, or restricting your intake of solid foods, is often promoted as a means of losing weight. Studies have suggested that intermittent fasting — alternating restricted food intake with usual eating patterns — may have several health benefits. Now, a study in mice suggests that fasting and then refeeding boosts cell regeneration in the intestines. However, the research found that this also increased the risk of intestinal tumors in the mice. Fasting has long been [...]

One 30-minute session of moderate walking can lower the systolic blood pressure of women with rheumatoid arthritis, according to a new study. Many people with rheumatoid arthritis also experience high blood pressure, which can lead to cardiovascular issues. The authors of the study believe the effect of these exercise sessions can result in a permanent lowering of systolic blood pressure. The study observed no similar reduction in diastolic blood pressure. Thirty minutes of moderate [...]

- Though many consider coconut oil healthy, a new study suggests otherwise. - The study finds that coconut oil disrupted mice’s ability to use leptin and insulin, two critical hormones, with insulin resistance being a primary characteristic of type 2 diabetes. - Nutritionists recommend unsaturated or polyunsaturated oils instead of saturated oils like coconut oil. Low doses of coconut oil added to the diet of mice for eight weeks led to alterations in [...]

Researchers say they are learning more about how gut bacteria can be used to treat autoimmune diseases. In a study involving mice, researchers say they have developed a probiotic that could be a treatment for multiple sclerosis. Experts say the probiotic would work in the same general way as diets do to control inflammation but may have longer-lasting effects. Gut bacteria have been shown to be vitally important to overall health. Now, a new studyTrusted [...]

Researchers investigated how immune cell function may affect the development of schizophrenia. They reported that immune factors in people with schizophrenia affect the growth of blood vessels in the brain. Further studies are needed to see whether this mechanism is involved in the development of schizophrenia. Schizophrenia is a chronic mental disorder. Its symptoms can include disorganized speech, delusions and hallucinations. About 24 million people have schizophrenia worldwide, [...]

A study of young Brazilian adults finds that even a mild-to-moderate case of COVID-19 can unbalance the autonomic nervous system, potentially leading to cardiovascular issues that become evident later in life. COVID-19’s effect on the autonomic nervous system makes sense considering how many organs and systems it seems to affect. Keeping a healthy body mass index (BMI) and maintaining a physically active lifestyle may reduce the imbalance. All data and statistics are based [...]

Researchers have wondered whether vitamin D may help people avoid SARS-CoV-2 infections and mitigate the effects of COVID-19. A randomized, double-blind, placebo-controlled clinical trial seeks to test vitamin D’s usefulness in combatting the disease. The study finds high doses of vitamin D have no effect on key COVID-19 outcomes in particularly ill hospitalized patients. Further research is needed to investigate whether a deficiency of vitamin D is associated with more severe cases of [...]
