In addition to an extensive Brexit strategy, Brits need more vitamin D. British health officials recommended that UK residents triple their intake with supplements in fall and winter, when the country’s weather is extra dreary.
The UK’s Scientific Advisory Committee on Nutrition conducted an extensive review of vitamin D research and are now recommending that adults and children four years and over take 10 micrograms of D daily from October through March to protect bone and muscle health. Children ages one to four, pregnant and breastfeeding women, and at-risk groups should take the supplement year-round. At-risk groups include ethnic groups with dark skin, elderly people and "people who wear clothing that covers most of the skin," according to the BBC.
Official estimates suggest one in five adults and one in six children in England may have low levels of the vitamin. Forty-two percent of U.S. adults are vitamin D deficient, according to a Nutrition Journal study, which found that African Americans and Hispanics had the highest rates of deficiency. In the U.S., the government recommends that adults get 15 mcg (600 IU) of vitamin D.
Experts have become concerned in recent years that rickets is re-emerging in children who do not get enough vitamin D, including kids who are always covered in sunscreen during the summer months and are not exposed to sunlight, according to Newsweek. Legions of sun-starved children during the Industrial Revolution were crippled by rickets, which the government largely obliterated the disease with spoonfuls of cod liver oil for children promoted through a massive campaign in the '50s. But in the last 15 years, the number of reported cases of rickets in hospitalized children has increased fourfold—from 183 cases in 1995 to 762 cases in 2011. Experts said the actual number is probably even higher since there's no official surveillance system and it's unknown whether the disease has peaked.
