Vitamin D Intake Lower Among UK South Asians

Vitamin D intake was found to be lower among UK South Asians. Public health strategies are required to tackle low intakes of vitamin D in the UK South-Asian population, reports a new study in the journal Public Health Nutrition.

In the largest study of its kind, using data from the UK Biobank, researchers from the University of Surrey examined the vitamin D intake of UK South Asian adults through diet and supplementation. This population group traditionally has inadequate vitamin D levels due to their darker skin pigmentation, low sun exposure to the skin due to dress coverage and a tendency to avoid the sun.

‘Vitamin D intake which is required for overall health was found to be low among UK South Asians which may lead to an increased risk of chronic illnesses such as osteoporosis, cancer, and cardiovascular disease. Public health strategies are mainly required to tackle low intakes of vitamin D in the UK South Asian population.’

This makes it even more important that they have adequate oral intake of vitamin D, through diet or supplements.

Examining 8,024 South Asians (Bangladeshi, Indian, and Pakistani) participants, researchers found low intakes of this vital vitamin. In tandem with a lack of sunlight exposure, this would put them at increased risk of chronic diseases including osteoporosis, cancer, and cardiovascular disease. Vitamin D is vital to our health as it helps regulate the immune and musculoskeletal system.

Researchers found that vitamin D intake through diet was low amongst this group at 1.0-3.0 micrograms per day, but there was a differentiation in ethnicity, with Bangladeshis having on average higher vitamin D intake (3.0mcg) than Indians (1.0mcg). However, all of the groups were below both the European Food Safety Authority recommendation (15 micrograms per day) and the Public Health England recommendation (10 micrograms per day), which is needed to ensure adequate health in adults.

Vitamin D supplementation use, which is a good way of increasing vitamin D levels in the body, was also low amongst UK South Asians, with only 22 percent of Bangladeshis, 32 percent of Indians and 25 percent of Pakistanis taking a vitamin D containing supplement.

Within this group, women (39 percent) were more likely to take supplements than men (23 percent).

Surprisingly researchers discovered a geographic and socioeconomic distinction in vitamin D intake in South Asians. It was found that South Asians in Greater London had a higher prevalence of vitamin D intake (35 percent) than those in other regions (18-28 percent).

Lead author Dr. Andrea Darling, from the Department of Nutritional Sciences at the University of Surrey, said: “Such low levels of vitamin D intake and vitamin D supplement use in this population group is very concerning. Vitamin D is crucial to ensuring our overall health, and a lack of it leads to an increased risk of chronic illnesses putting an additional strain on the NHS.

“Urgent steps are required to remedy this problem and avoid a public health crisis amongst UK South Asians.”
