Moderate Alcohol Intake Linked to Higher Brain Iron and Malfunction

A UK cohort study and Mendelian randomization (MR) suggested that moderate alcohol consumption [>7 units (56 g) alcohol weekly] was associated with markers of higher brain iron and worse cognitive function. The study included 20,729 UK Biobank participants (mean age 54.8 years, 48.6% female). Multiorgan susceptibility-weighted magnetic resonance imaging (~9.60 […]


Adding Salt to Foods Linked to Mortality and Life Expectancy

A prospective study indicates that the higher frequency of adding salt to foods is associated with a higher risk of all-cause premature mortality and lower life expectancy. The study included 501 379 participants from UK biobank. There were graded relationships between higher frequency of adding salt to foods and higher concentrations […]


Sleep Loss Predisposes to Abdominal Visceral Obesity

A US randomized, controlled, crossover study in healthy, nonobese individuals revealed that sleep restriction combined with ad libitum food promotes excess energy intake, weight gain and particularly central accumulation of fat without changing energy expenditure. The study included 12 healthy, nonobese individuals (9 males, age range 19 to 39 years), […]


Light Exposure Timing Influences Metabolism

A randomized, controlled, crossover trial in overweight insulin-resistant volunteers in the Netherlands suggested that in contrast to Dim day–Bright evening condition, Bright day–Dim evening condition mostly elicited favorable metabolic outcomes. The trial included 14 overweight 40–75 years male and female, insulin-resistant volunteers between July 2018 and November 2019. Participants were randomly […]


Causal Alcohol-Cancer Link Modified by Genotype

A prospective study in China revealed that certain genotypes of alcohol metabolism might reduce or exacerbate the effects of alcohol on several cancers. Aldehyde dehydrogenase 2 (ALDH2)-rs671 G>A and alcohol dehydrogenase 1B (ADH1B)-rs1229984 G>A were genotyped in 150 722 adults, enrolled from 10 areas in China from 2004 to 2008. […]


Olive Oil Intake Linked to Lower Mortality

Observational data from 2 prospective cohorts of U.S. men and women suggested that higher olive oil intake or replacing margarine, butter, mayonnaise, and dairy fat with olive oil were associated with lower risk of total and cause-specific mortality. The analysis included 60,582 women and 31,801 men from 1990 to 2018 […]


MIND Diet Linked to Better Cognitive Resilience

A US longitudinal clinical-pathologic study revealed that healthy diet is associated with cognitive resilience (defined as performing better than expected given burden of neuropathology) independently of common brain pathology in older adults. The study included 569 decedents with valid dietary data, cognitive testing proximate to death, and complete autopsy data. […]
