This Week’s Research Highlights
A preclinical study published in the journal Immunity found that dietary fiber increases survival in influenza-infected mice by setting the immune system at a healthy level of responsiveness. A high-fiber diet blunts harmful, excessive immune responses in the lungs while boosting antiviral immunity by activating T cells. These dual benefits were mediated by changes in the composition of gut bacteria, leading to an increase in the production of short-chain fatty acids through the microbial fermentation of dietary fiber. The study suggests that the modern Western diet, low in fiber and high in sugar and fat, could increase susceptibility to inflammatory diseases while decreasing protection against infections.
In this study, researchers collected mussels from eight places in Scotland to see what kinds of plastic were in them. On average, there were 3.2 pieces of plastic in each Mytilus mussel. But, the number of pieces depended on how much the mussel weighed. The researchers found people who eat more shellfish might eat up to 4620 pieces of plastic per year. However, the risk of eating plastic from mussels is very small compared to the risk of breathing in tiny pieces of plastic in dust around the house during meals. The presence of these plastic particles in food raises concerns about their potential health effects, such as inflammation, oxidative stress, and the possibility of ingesting harmful chemicals.
In this paper, resistance exercise training was found to significantly reduce depressive symptoms among adults, regardless of health status, total prescribed volume of resistance exercise training, or significant improvements in strength. There were no significant associations between the total volume of prescribed resistance exercise training, participant health status, or strength improvements and the antidepressant effect of resistance exercise training. However, smaller reductions in depressive symptoms were derived from randomized clinical trials with blinded allocation and/or assessment. The available empirical evidence supports resistance exercise training as an alternative and/or adjuvant therapy for depressive symptoms.
