Can this be the reason your mood is not good?
You want to be happy and not feel depressed, and while we don’t understand all the reasons for depression, new research suggests that low-grade systemic inflammation may be involved(Wium-Andersen MK, et al. 2013).
This is exactly what the reviewed research investigated by measuring plasma levels of C-reactive protein (CRP), an inflammatory marker. 73,131 participants both men and women between the age of 20 and 100 years were included.
The conclusion of the study was that elevated levels of CRP are associated with increased risk for psychological distress and depression in the general population.
Maybe this looks a little bit strange to you, but the food you eat could actually be contributing to this type of inflammation, and for that reason also affect your mood.

Vitamin D and Early Death
New research on the importance of vitamin D is published all the time. The reviewed study was quite large and was conducted in Denmark (Brondum-Jacobsen P, et al. 2012).
The participants were 10,170 men and women, the vitamin D levels were measured, and the follow-up time was 29 years. The researchers investigated the association between vitamin D levels and ischemic heart disease, myocardial infarction and early death.
The results documented that the risk of ischemic heart disease, myocardial infarction and early death were increasing when vitamin D levels were decreasing.
If you have not had your vitamin D level tested, I suggest that you get some sun and take approximately 2000 IU of vitamin D3 per day.
New research on vitamin D
Numerous studies in the last few years have documented a variety of health benefits provided by vitamin D.
While sun exposure is a good source of vitamin D many people today use sunscreen most of the time when they are outside. Vitamin D deficiency has been found to be fairly common even in warmer climates. For that reason most people will benefit from supplementing with vitamin D. 1000 to 2000 IU per day is usually adequate.
The research reviewed here is related to vitamin D status and prostate cancer (Fang F, et al. 2011). The investigators compared men in the lowest and highest quartile of 25 (OH) vitamin D levels and risk of death from prostate cancer or the development of bone metastases. 25 (OH) vitamin D is the most common form of vitamin D to test for.
The results showed that men in the lowest quartile of vitamin D were more likely to die of their cancer when compared to those in the highest quartile.

Optimal vitamin D level may help you lose more body fat
Vitamin D has been found to be important for numerous reasons. In a recent study it was also documented that women who had a higher blood level of 25 hydroxyvitamin D lost more body fat when compared with women with a lower 25 hydroxyvitamin D level (Ortega RM, et al, 2008). 25 hydroxyvitamin D is the preferred test for vitamin D status.
The study included overweight/obese women between the age of 20-35 years of age. The women were put on slightly caloric restricted diets which led to a reduction in body weight and body mass index in both the women with lower and higher vitamin D levels. What made this study interesting was that women with hydroxyvitamin D levels of 50 nmol/L or more lost more body fat than the women who had hydroxyvitamin D levels of less than 50 nmol/L.
We get vitamin D from sunshine, but because of less exposure and protection from sunscreens, most people need to supplement with vitamin D to reach optimal levels. Vitamin D3 is the recommended form to take.
