A review of studies performed by researchers from Warwick University shows that high levels of vitamin D in older people could help prevent heart disease and diabetes in older individuals. Vitamin D levels that were higher significantly decreased the risk of diabetes, metabolic syndrome and cardiovascular disease.
The study review revealed a 33 percent lower risk of heart disease in men and women from various ethnic groups, compared to low levels of vitamin D in 28 studies that included 99,745 participants. The risk of type II diabetes from high levels of vitamin D was reduced 55 percent, and metabolic syndrome risk declined by 51 percent.
The study, led by Johanna Parker and Dr Oscar Franco, Assistant Professor in Public Health at Warwick Medical School included publications from 1990 and 2009 from the US, Europe, Australasia, Iran and India.
Dr. Franco says, "We found that high levels of vitamin D among middle age and elderly populations are associated with a substantial decrease in cardiovascular disease, type 2 diabetes and metabolic syndrome", findings that are significant for curbing increasing rates of cardiovascular disease as well as the alarming incidence of type II diabetes.
Vitamin D from food sources, that include tuna, mackerel, salmon, fortified cereals and dairy products, sunlight, or supplements could reduce heart disease or diabetes by 43 percent among middle age and older individuals according to the findings.
Low levels of vitamin D has also been linked to increased chances of cancer, inability to lose weight, asthma, chronic pain, and greater risk of colds and flu. The new study shows that higher levels of vitamin D could provide substantial protection from cardiometabolic disorders that include heart disease and type II diabetes among older adults.
Grassrootshealth are a charity promoting Vitamin D awareness. Under the documentation tab you will find much interesting Vitamin D research. They also offer postal 25(OH)D testing to check your level is adequate.
ReplyDeleteThis chart links Vitamin D status with chronic disease incidence
From this you will see levels above 55ng/ml are associated with least risk of chronic disease incidence.
Around 60ng/ml we find human breast milk is replete with Vitamin D3
The graph in the Grassrootshealth banner shows roughly the range of daily intakes required to get most people in the natural primitive range (60~80ng/ml) that human bodies maintain living near naked outdoors as we evolved.
The most effective form of Vitamin D3 is found in oilbased gel caps. I prefer the ones in MCT oil as medium chain triglyceride oil is the most stable, we generally have to high an omega 6 level and the ones in fish oil are relatively expensive and most people require lot more omega 2 than a vitamin D capsule would provide.
Taking your vitamin D will the largest meal of the day maximizes the amount absorbed.
1000iu/daily for each 25lbs weight is usually sufficient. A 25(OH)D test after 12weeks will confirm this or not.
Up to 10,000iu/daily has been shown to be safe.
