This week, new research shows the dangers of fructose and further benefits of fruit & veg. UCLA scientists report omega-3 can reverse fructose damaged genes, research identifies key antioxidant that protects against immuno-inflammation related to brain ageing, sleep deprivation shown to reduce ‘good’ cholesterol.
Omega-3 Fatty Acids Can Reverse Fructose Damaged Genes
A new study published in EBioMedicine (published jointly by Cell and The Lancet) by UCLA life scientists found that fructose can damage hundreds of genes in the brain. Disruption was identified in the areas of metabolic, cell communication and inflammation regulation.
However, the researchers also discovered the omega-3 fatty acid, docosahexaenoic acid (DHA), seems to reverse the harmful changes. Xia Yang, a UCLA assistant professor said, “DHA changes not just one or two genes; it seems to push the entire gene pattern back to normal, which is remarkable”. Read article here.
Nrf2 Key Cytoprotective Antioxidant In Regulating Brain Ageing
An international researcher team led by the Italian University of Molise, published a fascinating brain ageing mechanistic review in Immunity & Ageing. The research looked at the protective role of phytochemicals from fruit and vegetables, herbs and spices inregulating immuno-inflammatory oxidative and nitrosative stress (IO&NS) seen in brain ageing. Transcription factor nuclear factor E2-related factor 2 (Nrf2) was identified as a key protective antioxidant. Nrf2 can be induced by the phytonutrients anthocyanin, catechin and epicatechin, found in red/blue coloured fruits and vegetables, cocoa and others. Read full study here.
Sleep deprivation may lower HDL cholesterol
Further evidence on the detrimental effects of sleep deprivation was recently published in Scientific Reports. The study found that, “just one week of sleep deprivation begins to change the body’s immune response and metabolism” said Vilma Aho, the study’s co-author. Lower circulating high density lipoproteins (HDL) was seen in the sleep deprived population. Read article here.
New student blog from CNELM student, Sharon Peck
On the last Friday of every month we invite a BANT student member to guest blog for our Student Spotlight page. This month, Sharon Peck, from the Centre of Nutrition Education & Lifestyle Management, talks about the her journey from nutritional wastelands to Nutritional Science student.
