Study review shows Vitamin D curbs risk of heart and metabolic disorders in older adults

A review from Wartick University researchers shows that 

higher levels of vitamin D starting in mid-life can substantially 

reduce the risk of cardiometabolic disorders in older individuals. 

The researchers found that compared to people with lower levels 

of vitamin D, heart disease, and Type II diabetes risk drops when 

higher levels of vitamin D are present in the body. 

Foods that are fortified with vitamin D or with high levels 

include salmon, tuna, and mackerel can raise vitamin D levels, 

potentially fending off type II diabetes and heart disease. 

Taking supplements of vitamin D3 can also boost vitamin D levels. 

The researchers analyzed 28 studies that included 99,745

 participants to find that higher levels of vitamin D yielded a 

33 percent reduction in the risk of heart disease, and a 55 percent 

lower risk of developing Type II diabetes among men and women 

from various ethnicities. The chances of developing metabolic 

syndrome declined by 51 percent for older adults with higher levels 

of vitamin D, compared to those with lower levels. 

Metabolic syndrome is described by the American Heart Association 

as a group of risk factors for disease that includes: "Abdominal obesity 

(excessive fat tissue in and around the abdomen) Atherogenic 

dyslipidemia (blood fat disorders — high triglycerides, low HDL 

cholesterol, and high LDL cholesterol — that foster plaque buildups

 in artery walls) Elevated blood pressure Insulin resistance or 

glucose intolerance (the body can’t properly use insulin or blood sugar) 

Prothrombotic state (e.g., high fibrinogen or plasminogen activator inhibitor–1 

in the blood) Proinflammatory state (e.g., elevated C-reactive protein in the blood) " 

According to Dr. Oscar Franco, Assistant Professor in Public Health at 

Warwick Medical School, "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". 

The finding that higher levels of vitamin D could reduce heart 

disease risk, diabetes type II, and metabolic syndrome 

are significant for public health. 

Consume foods that are fortified with or contain vitamin D naturally, or speak 

with your doctor about taking vitamin D supplements to reduce your 

risk of heart disease and diabetes.
