Do certain amino acids modify the risk of dementia linked to air pollution?
Higher levels of vitamin B-related amino acids may be linked to the risk of dementia associated with a certain type of air pollutants called particulate matter, according to a study published in the July 19, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study does not prove that […]
Not all micronutrients created equal: Study identifies some supplements that benefit cardiovascular health: A meta-analysis of more than 884 studies finds omega-3, folic acid and CoQ10 among the micronutrients that reduce risk
Healthy diets are rich in antioxidants like amino acids, omega-3 fatty acids and vitamin C, but exactly how beneficial these micronutrients are for cardiovascular health has long been controversial. Now a new meta-analysis published in the Journal of the American College of Cardiology provides some clarity. Researchers systematically reviewed a total of 884 studies available […]
Ubiquitous nutrients suppress appetite and promote movement
In experiments on mice, researchers at ETH Zurich show that non-essential amino acids act as appetite suppressants and promote the urge to move. Their research provides insight into the neural mechanism that controls this behaviour. Proteins can suppress appetite, so a protein-rich diet can help people lose weight. That’s just one of the reasons why […]
Study confirms nutrient’s role in childhood blood cancer: Evidence suggests dietary limits may help
A molecular building block of many animal proteins, the amino acid valine, plays a key role in cancerous growth seen in T cell acute lymphoblastic leukemia, a new study shows. Led by researchers at NYU Langone Health, its Department of Pathology, and the Laura and Isaac Perlmutter Cancer Center, the study showed that genes involved […]
Men and women of Roman Herculaneum had different diets, new research shows
Researchers — led by the University of York’s BioArCh team — developed a new approach to analyse amino acids, the building blocks of proteins, from 17 adult skeletons found in the aftermath of the eruption of Vesuvius in 79 AD. By measuring the isotopes of carbon and nitrogen in the bone amino acids, the researchers […]
Study identifies molecule that stimulates muscle-building in humans
In a randomized control study of 10 healthy young men, researchers compared how consuming the single amino acid leucine or its two-molecule equivalent, dileucine, influenced muscle-building and breakdown. They found that dileucine boosts the metabolic processes that drive muscle growth 42% more than free leucine does. They report their findings in the Journal of Applied […]
