  Green tea's cognitive benefits for middle-aged and elderly Chinese people were confirmed in a study from Wuhan University (Zhang R, et.al., 2022).   Regular drinkers of green tea showed higher scores in memory and executive function tests, and lower indicators of Alzheimer's disease. It was found that these positive...

  The researchers of the following study examined the effects of magnesium (Mg) supplementation on C-reactive protein (CRP) levels, a marker of inflammation (Mazidi M, et.al., 2018).   They conducted a systematic review and meta-analysis of randomized controlled trials and found that Mg supplementation led to a significant reduction in...

An interesting study found that high egg consumption may be linked to an increased prevalence of coronary atherosclerosis (Choi Y, et.al., 2015). The study, which examined over 23,000 asymptomatic adults without a history of cardiovascular disease or hypercholesterolemia, found that those who ate seven or more eggs per week had...

A new study has found that physical activity is linked to a healthier brain (Fox FAU, et.al. 2022). The study, which examined data from over 2,500 participants using MRI and other tools, found that physical activity dose and intensity were independently associated with larger brain volumes, gray matter density, and...

The following study reviewed research on the importance of glutathione. Diseases, including chronic obstructive pulmonary disease, atherosclerosis, stroke, cancer, and COVID-19 involve inflammation and excessive production of reactive oxygen species that reduce the levels of glutathione. Glutathione is a tripeptide produced by the body that plays a vital role in...

The following study shows that physical activity can improve brain health. Researchers examined whether physical activity is related to brain volume, cortical thickness, and gray matter density in a large study of 2,550 participants. They found that physical activity dose and intensity were independently associated with larger brain volumes, gray...

An interesting study suggests that maintaining high cardiovascular fitness in midlife could help decrease the risk of dementia in women. Researchers followed a population-based sample of 1,462 women between the ages of 38 and 60 for 44 years. Women with high fitness levels had a lower risk of developing all-cause...

The purpose of this study was to assess the association of habitual glucosamine use with risk of cardiovascular disease events (Ma H, et.al., 2019). 466039 participants were followed for a median follow-up of seven years. The cardiovascular events included cardiovascular death, coronary heart disease, and stroke.     After adjustment...

This research examined the association between dietary magnesium intake and brain volumes (Alateeq K, et.al., 2023). The participants were between the ages of 40 and 73 years old. On average, higher baseline dietary magnesium intake was associated with larger brain volumes (gray matter; left hippocampus; and right hippocampus).   The...

This study examined the effect of exercise intensity on senescence in skeletal muscle, using a randomized counter-balanced crossover design (Jean WH, et.al., 2023). Senescence is the loss of a cell’s ability to divide and grow. Biopsies of the vastus lateralis muscle of 9 sedentary men with an average age of...

This study compared the risk of contracting 3 coronavirus infections in participants with different levels of the omega 3 fatty acid DHA (Harris WS, et.,al.,2023). The DHA levels (% of total fatty acids) were measured by nuclear magnetic resonance. The results were interesting.   This is what the researchers concluded....

This study included 1048 participants between the age of 50 and 80 years old without cardiovascular disease (Hu T, et. al., 2023). The researchers investigated the associations of 2-year changes in fat percentage and fat-free mass percentage with occurring cardiovascular events.   This is what they found. The participants with...

Inflammation is an important part of the body's immune response that involves immune cells, cell-signaling proteins, and pro-inflammatory factors. Systemic inflammation plays a role in the development of many chronic diseases, including cancer, cardiovascular disease, and diabetes.   C-reactive protein is an important blood marker of systemic inflammation.This study investigated...

This study included 2315 men between the age of 42 and 60 years (Laukkanen T, et.al., 2015). The purpose of the research was to investigate the association of frequency and duration of sauna bathing with the risk of sudden cardiac death, fatal coronary heart disease, fatal cardiovascular disease, and all-cause...

This study included 2,315 healthy men between the age of 42 and 60 years (Laukkanen T, et. al., 2017). The researchers investigated whether frequency of sauna bathing is associated with the risk of dementia and Alzheimer's disease. The sauna they used was a traditional Finish sauna. The results showed that...

In this research 11 studies on black tea and 24 studies on green tea were analyzed for an association of tea consumption and the risk of cardiovascular disease ( Yang X, et.al., 2022).     The results showed that drinking less than four cups of black tea daily may prevent...

In this research a total of 341,248 adults with an average age of 39.7 years were included, and the follow up were 15-years (Chen LJ, et.al., 2022). The participants reported sleep duration and also disturbances (difficulty falling asleep, easily awakened, and if they used sleeping medication. The participants’ physical activity...

In the following study the researchers investigated whether low vitamin D levels were associated with gray matter volumes, whole brain volumes and hippocampus volumes (Terock J, et.al., 2023). Structural MRI data and vitamin D levels were obtained for the 1,865 participants, and this was what they found. Vitamin D deficiency...

In this research the effect of oral glutathione supplementation was studied in obese subjects with and without type 2 diabetes (Søndergård ST, et.al., 2021). Insulin sensitivity and markers of oxidative stress were measured at the beginning of the study and after 3 weeks. The participants were given either 1000mg daily...

Brain-derived neurotrophic factor (BDNF), is a protein involved in neuroplasticity, learning and memory. The following study evaluated the isolated and interactive effects of 20-h fasting, 90-min light exercise, and high-intensity exercise on peripheral venous BDNF in 12 human volunteers. (Gibbons TG, et.al., 2023).     The researchers found that fasting...
