Chronic disease dating
Professor Karl Michaëlsson, of Uppsala University in Sweden, writing in a Lancet commentary, said: ‘Without stringent indications - i.e.supplementing those without true vitamin D insufficiency - there is a legitimate fear that vitamin D supplementation might actually cause net harm.’Two months ago the chief medical officer, Dame Sally Davies, called for free vitamins to be given to children after it emerged that a quarter of youngsters are short of vitamin D.
Scientists claim there is no evidence to support taking vitamin D supplements to stave off chronic disease and early death - and results of several multi-million dollar trials currently under way are unlikely to alter this view.
A new review examines existing evidence from 40 randomised controlled trials - the gold standard for proving cause and effect - and concludes that vitamin D supplementation does not prevent heart attacks, strokes, cancer, or bone fractures in the general population by more than 15 per cent.
Some scientists assumed vitamin D, which is produced naturally by exposure to sunlight, could protect against disease because patients with cancer, heart disease or Alzheimer’s, or who died prematurely, often had very low levels of the nutrient.
In the latest study, Dr Mark Bolland of the University of Auckland, New Zealand, and colleagues used several types of review of existing studies, including a ‘futility analysis’, to predict whether future research results might sway existing evidence.
The researchers found that those who consumed butter at a third serving to more than three servings did not have increased risk of cardiovascular disease and diabetes. Tuft scientist Laura Pimpin said that butter should not receive so much flak as it is considered to be a "neutral" food, Science Daily noted.
Butter is used in different dishes and how it is consumed and paired with another food will decide how it impacts a person's health. Dariush Mozaffarian said that butter should not be considered an enemy in the food pyramid or in having good health.There are many factors that cause heart disease and other conditions, and no food is singularly responsible for its development.She added: ‘Vitamin D supplements are not intended for treating any disease conditions, and it is disappointing this review did not address the essential role of vitamin D in bone and musculoskeletal health.‘In the light of the findings that 75 per cent of the British population have below recommended intakes of vitamin D and that vitamin D is essential for bone health as well as a number of other physiological functions, consideration should be given to everyone taking a vitamin D supplement all year round.Butter's nutriotinal content is always misunderstood in the food pyramid.In a new study, researchers found that it is a "middle-of-the-road" kind of food where health outcomes are largely dependent on how it is consumed.Butter Not Linked with Chronic Heart Disease and other Conditions In a new study published in the journal PLOS ONE, scientists reviewed various studies to find out if butter can cause chronic heart disease and other conditions.
