|Health food for sick people - Much better than cholesterol supplements ;-)|
The latest piece to the pro-cholesterol puzzle is a study from the Capital Medical University (Wang. 2016) in Beijing, China. A study in which the researchers tried to get to the bottom of the proven link between cholesterol and several adverse outcomes in various disesase - especially infectious ones.
The authors conducted a study to supplement cholesterol, and observe the change on the test indexes and the severity of disease. Their randomized and controlled clinical trial was conducted at the infectious disease department in Beijing Friendship Hospital, Capital Medical University, Beijing, between January 2011 and December 2012.
The subjects were hospitalized patients with pulmonary infection, patients who were assigned into intervention group and control group randomly and subsequently received a 10-day course of either
- extra 600mg cholesterol per day (provided by the egg yolk) or
- a placebo supplement devoid of cholesterol, but w/ the equivalent amount of vitamin A

t intake of below 30% of the predetermined optimal energy intake for each of the patients, the scientists tried to ensure that no external factors would interfere with the recovery of their hospitalized (=tightly controlled) patients.

Now, you can argue that all that may be due to other ingredients in the egg-yolk, but let's be honest: if infections, especially pneumonia and pulmonary infection disease, can lead to hypocholesterolemia and supplementation of cholesterol properly can improve the nutritional status, decrease the severity of disease, and improve the prognosis of disease, that's quite a convincing piece of evidence in favor of the importance of cholesterol in our bodies' fight against infections.
"The increased concentrations of TC, ALB and PA in intervention group were more than those changes in control group. The BMI in intervention group was increased more than that in control group.

The decreased concentrations of CRP and IL-6 in intervention group were more than those changes in control group. The improvement of severity of disease in intervention group was more obvious than that in control group. The improvement of nutrition status in intervention group was significant" (Wang. 2016).
