This week we have a range of issues the published papers discuss: nutrition vs lifestyle diseases, nutrition vs depression and anxiety, activity levels of particular populations during the COVID-19 crisis, the potential injury risks of lowered activity during COVID-19 lockdown on contact sport athletes and more.
Here are the highlights:
People with high cholesterol should eliminate carbs, not saturated fat, study suggests
An international team of experts on heart disease and diet say there's no evidence that a low-saturated fat diet reduces cholesterol in people with familial hypercholesterolemia.

Probiotics alone or combined with prebiotics may help ease depression
But possible contribution to lessening anxiety not yet clear, evidence review suggests
Probiotics either taken by themselves or when combined with prebiotics, may help to ease depression, suggests a review of the available evidence.

Nutrients in microalgae: An environmentally friendly alternative to fish
Microalgae could provide an alternative source of healthy omega-3 fatty acids for humans while also being more environmentally friendly to produce than popular fish species. The study offers an initial indication of the environmental effects of producing microalgae in Germany.

Brain benefits of exercise can be gained with a single protein
Findings open door to drugs that could help protect the aging brain
A little-studied liver protein may be responsible for the well-known benefits of exercise on the aging brain, according to a new study in mice. The findings could lead to new therapies to confer the neuroprotective effects of physical activity on people who are unable to exercise due to physical limitations.

Antioxidants in corn line could aid human IBD protection, therapy
Flavonoids from a specific line of corn act as anti-inflammatory agents in the guts of mice with an inflammatory-bowel-disease-like condition, according to a team of researchers who said flavonoid-rich corn should be studied to determine its potential to provide a protective effect on human health.

Physical activity of older people requires tailored monitoring
Commercial activity monitors may underestimate the exertion level of older adults' activity
The ability to move about may deteriorate when aging, a phenomenon which needs to be considered when assessing physical activity in older people.

Healthier school food and physical activity environments matter for childhood obesity
School food choices and number of physical activity facilities are associated with students' BMI
Students at elementary and secondary schools that offer healthier food offerings and more opportunities for physical activities have a healthier body mass index, according to researchers. The study, published in Preventive Medicine Reports, uses professional measures of students' height and weight -- the gold standard for studying childhood obesity -- in a study on the effects of a school's food offerings and physical activity environment.
