Scientists have made discoveries in a wide range of topics in this past week. From links between genes and exercise outcomes to a ranking system to categorise food based on their healthfulness to breath-regulating garments.
Genes play key role in exercise outcomes
A new study has found that genes can explain up to 72% of the difference in outcome between people after a specific fitness exercise. The research involved data from 3,012 adults and has identified a number of specific genes which influence the outcomes of different physical activities.

Ranking healthfulness of foods from first to worst
New nutrient profiling system, most comprehensive and science-based to date, clears up confusion to benefit consumers, policymakers
Food Compass, a new nutrient profiling system, rates the healthfulness of foods, beverages, and mixed meals on a score of 1-100 based on a wide range of science-based attributes. This adaptable tool aims to encourage healthier choices, spur industry reformulation, and guide nutrition policies.

Key protein linked to appetite and obesity in mice
Researchers have identified a protein that plays a key role in how the brain regulates appetite and metabolism. Loss of the protein, XRN1, from the forebrain, resulted in obese mice with an insatiable appetite, according to a new study.

Americans are eating more ultra-processed foods
18-year study measures increase in industrially manufactured foods that may be contributing to obesity and other diseases
Consumption of ultra-processed foods has increased over the past two decades across nearly all segments of the U.S. population, according to a new study.

New fibers can make breath-regulating garments
'Robotic' textiles could help performers and athletes train their breathing, and potentially help patients recovering from postsurgery breathing changes.
A new kind of fiber can be made into clothing that senses how much it is being stretched or compressed, and then provides immediate tactile feedback in the form of pressure, lateral stretch, or vibration. Such fabrics could be used in garments that help train singers or athletes to better control their breathing, or that help patients recovering from disease or surgery to recover their breathing patterns.

Illness-and death-related messages found to be significant motivators for exercise
Fitness apps that emphasize illness- or death-related messaging are more likely to be effective in motivating participation than are social stigma, obesity, or financial cost messaging, according to a recent study.

Filling half of kids' plates with fruits and veggies helps increase consumption
Filling half of a child's plate with fruits and veggies isn't just recommended by the United States Dietary Guidelines, it also helps increase the amount of produce that kids end up eating, according to new research.
