Vitamin D and calcium supplements do not appear to protect against bone breaks or hip fractures in adults over the age of 50, according to a new study reported on by the Washington Post.

Why it matters: Fractures related to osteoporosis can have social and economic impacts that, as the world's population ages, are expected to increase. Researchers have been examining the association between supplements and fracture risk amid conflicting studies of the issue.

How it was done, per the Post: Researchers in China randomly analyzed 33 clinical trials involving more than 50,000 adults over the age of 50 who live in the general community. It didn't include those in nursing homes, hospitals and other facilities.

The limitations: Daniel Fabricant, president of the Natural Products Association, which represents manufacturers and retailers that make dietary supplements, told the Post the study's conclusion was "too broad of a brush." He claimed "there is a lot missing" because the study focuses on the healthiest segment of the population: "people with prior breaks or family incidence of osteoporosis may still need vitamin D."

The Post also noted that some of the trials included in the analysis did not test baseline vitamin D blood concentration for all participants. The study also didn't look into the benefits or risks of vitamin D supplements on other conditions. However, previous studies have shown they can lower risks of diabetes and certain cancers.

Former White House press secretary Sarah Huckabee Sanders will announce Monday that she's running for governor of Arkansas.

The big picture: Sanders was touted as a contender after it was announced she was leaving the Trump administration in June 2019. Then-President Trump tweeted he hoped she would run for governor, adding "she would be fantastic." Sanders is "seen as leader in the polls" in the Republican state, notes the Washington Post's Josh Dawsey, who first reported the news.

Coronavirus has inflamed global inequality

History will likely remember the pandemic as the "first time since records began that inequality rose in virtually every country on earth at the same time." That's the verdict from Oxfam's inequality report covering the year 2020 — a terrible year that hit the poorest, hardest across the planet.

Why it matters: The world's poorest were already in a race against time, facing down an existential risk in the form of global climate change. The coronavirus pandemic could set global poverty reduction back as much as a full decade, according to the World Bank.
