Global study links consumption of ultraprocessed foods to preventable premature deaths
A study analyzing data from nationally representative dietary surveys and mortality data from eight countries (Australia, Brazil, Canada, Chile, Colombia, Mexico, United Kingdom, and United States) shows that premature deaths attributable to consumption of ultraprocessed foods (UPFs) increase significantly according to their share in individuals’ total energy intake. The new study, appearing in the American […]
Dietary Thiamine Linked With Cognition
Dietary thiamine (vitamin B1) intake was linked with cognition in older adults, a longitudinal analysis in China suggested. Over a median follow-up of 5.9 years, cognitive decline risk was minimal at dietary thiamine intake levels of 0.60 to 1.00 mg/day, reported Xianhui Qin, MD, of Southern Medical University in Guangzhou, and co-authors. However, a J-shaped […]
Healthy diet early in life seems to protect against inflammatory bowel disease
Having a high dietary intake of fish and vegetables at 1 year of age, and a low intake of sugar beverages, seems to protect against inflammatory bowel disease. These are the findings of a study with more than 80,000 children conducted at the University of Gothenburg. The global rise in inflammatory bowel disease (IBD), which […]
How plant-derived nutrients can affect the gut and brain
Prebiotics are used to foster the colonisation of beneficial bacteria in the gut. These indigestible dietary fibres are found in plant-derived foods such as onions, leeks, artichokes, wheat, bananas, and in high concentrations in chicory root. They support gut health by promoting the growth and activity of beneficial gut bacteria. Researchers have now investigated whether […]
Autopsies Show Relationship Between Alzheimer’s Pathology and Diet in Older Adults
Healthy, plant-based dietary patterns were linked with less postmortem Alzheimer’s disease pathology, primarily beta-amyloid load, in older adults. Both MIND diet scores (β -0.022, P=0.035; standardized beta -2.0) and Mediterranean diet scores (β -0.007, P=0.039; standardized beta -2.3) were significantly associated with lower global Alzheimer’s pathology, reported Puja Agarwal, PhD, of Rush University in Chicago, […]
Fiber discovery could shape better gut health
Changing the structure of a dietary fibre commonly found in a range of food products has been found to promote healthy gut bacteria and reduce gas formation, a finding that could help people with intolerances to fibre and irritable bowel conditions. A team of scientists from the University of Nottingham, Quadram Institute Biosciences and the […]
Dietary change starves cancer cells, overcoming treatment resistance: Laboratory research finds a low-protein diet can enhance standard treatment for colon cancer
A dietary change could be a key to enhancing colon cancer treatment, a new study from the University of Michigan Rogel Cancer Center finds. Cancer cells need nutrients to survive and grow. One of the most important nutrient sensing molecules in a cell is called mTORC1. Often called a master regulator of cell growth, it […]
Popular dietary supplement causes cancer risk, brain metastasis, study finds
While previous studies have linked commercial dietary supplements like nicotinamide riboside (NR), a form of vitamin B3, to benefits related to cardiovascular, metabolic and neurological health, new research from the University of Missouri has found NR could actually increase the risk of serious disease, including developing cancer. The international team of researchers led by Elena […]
A common dietary fiber promotes allergy-like immune responses in preclinical studies
A type of dietary fiber called inulin, commonly used in health supplements and known to have certain anti-inflammatory properties, can also promote an allergy-related type of inflammation in the lung and gut, and other parts of the body, according to a preclinical study from researchers in the Friedman Center for Nutrition and Inflammation and Jill […]
Sugar disrupts microbiome, eliminates protection against obesity and diabetes
A study of mice found that dietary sugar alters the gut microbiome, setting off a chain of events that leads to metabolic disease, pre-diabetes, and weight gain. The findings, published today in Cell, suggest that diet matters, but an optimal microbiome is equally important for the prevention of metabolic syndrome, diabetes, and obesity. Diet alters […]
