Beta-lactoglobulin is a protein in breast milk. It binds to retinol, a form of vitamin A that plays a crucial role in neurodevelopment, facilitating its transport. A recent study found that nanoplastic exposure induces structural changes in beta-lactoglobulin, impairing retinol binding and transport. Researchers conducted a multi-part study to investigate the effect of polystyrene nanoparticles on beta-lactoglobulin. First, they measured changes in the protein's structure and its ability to bind retinol. Then, they examined polystyrene's effects on lysozyme, an antibacterial protein found in ... nutrition development vitamin a breast milk Microplastics

Watch nowAlzheimer’s disease, the most common type of neurodegenerative disease in older adults, causes a progressive deterioration of cognitive function. Recent research indicates that folate (vitamin B9) deficiency may play a role in Alzheimer’s pathology (https://faseb.onlinelibrary.wiley.com/doi/abs/10.1096/fasebj.30.1_supplement.1171.10?legid=fasebj%3B30%2F1_Supplement%2F1171.10&related-urls=yes) along with other micronutrients, such as vitamin A (https://pubmed.ncbi.nlm.nih.gov/28130638/). A recent systematic review and meta-analysis reports that folate deficiency increases the risk for Alzhe... brain alzheimer's micronutrients folate neurodegeneration

Consequently, 80 percent of deaths due to COVID-19 in the United States have been among adults 65 years of age and older. Researchers investigated the use of a ketogenic diet in mice as a strategy for treating COVID-19. A ketogenic diet is a high fat, low carbohydrate diet. Adherence to a ketogenic diet reduces blood glucose levels, which are associated with increased inflammation. Adopting a ketogenic diet may be an effective strategy for limiting excessive i... diet immune system ketogenic diet
Read moreReaction time and mood were improved in young individuals that consumed blackcurrant berry drink with 500 mg of polyphenols compared to placebo in a small pilot randomized controlled trial. EEG data also showed the blackcurrant drink changed brainwave activity. This was a small trial with a crossover study design, which means each person serves as their own control. Both the blackcurrant drink and the placebo drink had 6.98 g of sugar (glucose +fructose). They also both had the same amount of vitamin C...the only difference was that the placebo drink lacked the 500 mg of polyphenols. Conclusio... brain diet vitamin a polyphenol

The participants were randomly divided into either a group who were asked to make comprehensive changes in diet and lifestyle or a comparison group who were not asked to do so. > [...] After one year, the researchers found that PSA levels (a protein marker for prostate cancer) decreased in men in the group who made comprehensive lifestyle changes but increased in the comparison group. There was a direct correlation between ... exercise cancer diet prostate vitamin a protein aerobic
