Increased intakes of carotenoids may lower the risk of hip fracture in older men and women, according to a 17-year study from the US.
The researchers measured the intakes of total and individual carotenoids, including beta-carotene, lycopene, and lutein plus zeaxanthin. Intakes were assessed using a questionnaire (1). Over the course of 17 years of follow-up, the researchers documented 100 hip fractures. The highest average intake of all carotenoids was associated with a significantly lower risk of hip fracture and non-vertebral osteoporotic fracture. Of the individual carotenoids studied, lycopene was found to have the greatest protective effect.
These results suggest a protective role of several carotenoids for bone health in older adults. Aging populations and the additional strain from obesity increase the numbers affected by osteoporosis. Already the lifetime risk for a woman to have an osteoporotic fracture is 30–40% and in men the risk is about 13%.

Air pollution is a global problem with far-reaching consequences. Fine particulate matter known as PM2.5 increases the risk of illness and mortality from non-communicable diseases, especially cardiovascular and respiratory diseases. The supplementation of micronutrients with antioxidant capabilities such as vitamins B, C, E and marine omega-3 fatty acids has been shown to offset some of the worst effects of PM2.5 inhalation.

A new review says that supplementation with omega-3 fatty acids does not seem to reduce the risk of cardiovascular events and mortality for patients with a history of cardiovascular disease. Experts criticize that the review did not include many studies that showed a preventive effect.
