Compared with adults, children and adolescents are less sensitive to the sweet taste and need 40% more sucrose in a solution for them to detect the taste of sugar, a new study found. Along with higher taste-detection thresholds, both children and adolescents prefer significantly more concentrated levels of sweetness than adults.
For years, a scientific puzzle has bedeviled researchers aiming to fight Alzheimer's disease, a common and incurable form of dementia. The results of numerous lab investigations and population studies support the preventive potential of omega-3 fatty acids, "good fats" found abundantly in fish. However, to date the majority of studies evaluating omega-3s for averting or curtailing cognitive decline in human participants have failed to show benefits.
Microalgae may provide an alternative source of fish-derived omega-3 fatty acids, while also proving to be more environmentally friendly to produce, says German researchers.
