This is right from the Vitamin D Council website.... While the article is titled "New trial suggest Vitamin D improves quality of life markers in healthy women" when you go to the paper cited it shows that they were really looking for the cardiometabolical protective effects of Vitamin D which are seen in population with high sun exposure... and the study failed to show any. The Vitamin D Council summary of the article states the following in contrast to the headline  "Many observational studies have noted that people with more sun exposure have better cardiovascular health. This includes a more favorable lipid profile, lower blood pressure, and better insulin sensitivity. These benefits have been attributed to increased vitamin D production, but randomized controlled trials (RCT) have had conflicting results regarding the effects of vitamin D supplementation on cardiovascular markers."     Could this be because the RCT's use Vitamin D administered...

Dairy fat is a complicated topic because it is typically around 70% saturated fat but shows very inconsistent effects on blood lipids and cardiovascular disease (CVD) risk. However, if we narrow things down farther from dairy fat and focus on the foods which contain it, there is a lot of evidence from randomized controlled trials that diets high in saturated fat derived largely from butter fat increases LDL-c, whereas cheese intake results in lower LDL-c compared with butter of equal fat content. However, every trial showing these effects has used very high amounts of butter. For instance, one study replaced 13% of the subject’s caloric intake with butter, which corresponded to an average of 50 grams (almost one-half of a stick) of butter per day. In order to evaluate the effects of moderate butter consumption on CVD risk factors, Engel and Tholstrup from the University of Copenhagen, Denmark recruited 47 healthy...

It was recently reported by an updated Cochrane Review that reducing saturated fat intake lowered the risk of having a heart attack without affecting the risk of dying from one. These effects were most pronounced when the saturated fat (SFA) was replaced by linoleic acid (PUFA), but there was surprisingly no observable benefit of replacement with monounsaturated fats (MUFA). However, the trials included in this meta-analysis were primarily interventions where only dietary advice was given to the participants who were then followed for some time, and the majority of participants were those who were at a high-risk of cardiovascular disease (CVD) and/or already had a heart attack. Thankfully, researchers from the University of Reading, UK recently published findings from the DIVAS study that should help shed some light on the issue of fat quality and CVD. The DIVAS study was a 16-week 195-person intervention in which the participants were randomized to...

Eating more veggies doesn’t help those at risk for heart attacks. It is probably one of the most ubiquitous nutrition recommendations in existence – eat more vegetables. Only recently have researchers from Ireland actually put this to the test in overweight-obese men and women. All 89 of the participants were habitual low-veggie consumers with no outstanding medical history other than a blood lipid panel that put them at a high risk for heart disease. Over a 4-week run-in period, all participants consumed <2 servings of vegetables per day (1 serving = 80g), after which they were randomly allocated to consume 2, 4, or 7 portions per day for the following 12 weeks. There were literally no changes in any outcome, including body composition, blood lipids, blood pressure, or C-reactive protein. Reducing saturated fat consumption may reduce the risk of having a heart attack, but it won’t protect you from dying from...
