AIR POLLUTION LINKED TO ALZHEIMER’S Australian scientists examined the impact of air pollution on brain health in mice, as well as human brain cells in the lab. “Previous studies have indicated that people who live in areas with high levels of air pollution are at greater risk of developing Alzheimer’s disease,” said Cindy Gunawan, Ph.D. Tiny particles of the mineral magnetite are found in air pollution caused by vehicle exhaust, wood fires, and coal-burning plants. “Magnetite, a magnetic iron oxide compound, has also been found in greater amounts in the brains of people with Alzheimer’s disease.” In the new study, published in Environment International, mice exposed to magnetite showed a loss of neurons in the hippocampus and in the somatosensory cortex, which is consistent with the development of Alzheimer’s.
B VITAMIN IMPROVES WALKING IN PAD PATIENTS A double-blind, randomized clinical trial published in Nature Communications found that the over-the-counter supplement nicotinamide riboside, a form of vitamin B3, can increase walking endurance in patients with peripheral artery disease (PAD). This common condition, in which narrowed arteries reduce blood flow to the arms or legs, causing increased dificulty walking, has few effective treatments. Patients who took nicotinamide
riboside daily for six months increased their walking distance by more than 57 feet, compared to patients who took a placebo, whose walking became worse.
SUNLIGHT RELEASES CHEMICALS IN PLASTIC WATER BOTTLES Plastic water bottles exposed to sunlight causes them to degrade and release toxic volatile organic compounds (VOCs), which can be harmful when ingested. A study, published in Eco-Environment & Health, that analyzed six types of plastic water bottles exposed to ultraviolet A and sunlight found that all of the bottles emitted VOCs, including alkanes, alkenes, aldehydes, and carcinogens, such as n-hexadecane. “Consumers need to be aware of these risks, especially in environments where bottled water is exposed to sunlight for prolonged periods,” said lead researcher Huase Ou, M.D.
THINK YOU HAVE COVID? WAIT TWO DAYS TO TEST CU Boulder researchers found that while viruses that cause influenza A and B and RSV can be detected when you first feel symptoms, testing too soon can miss as many as 92% of COVID-19 cases. That is because, with most people already previously exposed, their immune systems are primed to react when they encounter COVID-19 again, and that immune response itself causes symptoms, according to the study published in Science Advances.

In addition, new variants in people with some immunity grow slightly more slowly than the original strain. “Our symptoms are happening sooner, but it takes longer to reach enough virus in your body for it to be detectable,” said researcher and doctoral student Casey Middleton.
SUGAR SUBSTITUTE RAISES RISK OF HEART ATTACK AND STROKE Xylitol, a low-calorie sugar alcohol, is promoted as a healthy alternative to sugar and is used in sugar-free candy, baked goods, and toothpaste. A study published in the European Heart Journal found that xylitol increases the risk of blood clots, which can lead to heart attack and stroke. “This study gives us more evidence that any sugar substitute is not appropriate, and we need to be careful,” said cardiologist Chauncey Crandall, M.D., author of the popular newsletter Heart Health Report. “Xylitol is in all type of products, and you need to stay away from it. We need to get away from all the sugar substitutes, period.”
