New Study – Prenatal supplementation with marine omega-3 DHA results in epigenetic changes in the resulting infants
Vitamin D deficiency has been linked to the development of osteoporosis and hip fractures as well as to other skeletal and non-skeletal disorders. Beside ‘severe deficiency’ (serum 25-hydroxyvitamin D levels below 25 nmol/liter) and ‘deficiency’ (serum 25(OH)D below 50 nmol/l), there is ongoing debate as to the exact definition of vitamin D ‘insufficiency’– a mild degree of vitamin D deficiency (between 50 and 75 nmol/l).
The National Diet and Nutrition Surveys (NDNS) are a series of government-funded surveys of food intake, nutrient intake and nutritional status of the British population (adults aged 16 to 64), undertaken to support nutritional policy and risk assessment. In 2008, the UK Scientific Advisory Committee on Nutrition (SACN) reviewed the latest NDNS, carried out between July 2000 and June 2001, to identify specific health outcomes where the population fails to meet dietary recommendations and specific groups are at risk. In addition, the SACN provided practical proposals for improvement where sections of the population had been shown to consume a poor diet.
