As summer approaches in the Northern Hemisphere, we look forward to spending more time outdoors. This is good because our skin can synthesize vitamin D when exposed to sunlight. With most people spending most of their days indoors, serum 25(OH)D concentrations are known to decrease through the fall and winter months. The most recent data (NHANES 2007-2014) finds 24% of Americans have insufficient vitamin D levels (<50 nmol/L).

Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in North America. Yesterday, I discussed the prevalence of suboptimal vitamin E status and its role in maintaining normal liver function. With more and more people being overweight and diagnosed with type 2 diabetes, the prevalence of NAFLD is increasing
Good news! Nationally representative data collected between 1999 and 2012 finds a reduction in the severity of metabolic syndrome among US adolescents. It was a linear trend. Interestingly, increasing unsaturated fat intake was beneficial. You may ask why.
Vitamin E is found in many foods (in small quantities) but most often in association with unsaturated fats – vegetable oils, nuts, and seeds – to protect them from oxidation. In brief, people eating more unsaturated fat will likely be consuming more vitamin E.
Did you eat enough dietary fiber today? Hoping so. In the effort to maintain a healthy weight, conversations involving energy balance swirl around physical activity and sources of calories. Alcohol provides empty calories. Too much protein challenges kidneys and grain proteins contain gluten. Fats are so calorie dense (>2x proteins and carbs). Last but not least, carbohydrates, too often consumed as sugar. We forget that dietary fibers are a form of carbohydrate. High fructose corn syrup and added sugars are often vilified as the evil causes of obesity and diabetes.
The American Heart Association recognizes metabolic syndrome as a combination of factors that multiply a person’s risk for heart disease, diabetes and stroke. With ~ 34% of American adults being affected, metabolic syndrome is an important health concern.
Oxidative stress is thought to play an important role in the pathologies of chronic non-communicable diseases and cancer. In a new publication, Sugiura and colleagues report higher serum β-carotene concentrations are associated with ~50% lower risk of metabolic syndrome
