Since I wrote my tips to being healthier about a week ago, I have seen several short stories on the news on the importance of vitamin D throughout the winter season. Although I briefly mentioned this in my list, it seems like a bit of elaboration could convince many of you that it is a worthwhile supplement since so many health professionals are recommending it to the public.
"According to Holick, a professor of medicine, physiology, and biophysics, and director of the General Clinical Research Center at Boston University School of Medicine and Director of the Bone Healthcare Clinic at Boston Medical Center, it has been estimated that 1 billion people world-wide are vitamin D deficient or insufficient." Dr. Holick would like to see the recommended intake of V-D increased to 800-1000IU - which is not obtainable through a normal diet. As much as we can try to consume a perfect amount of fish which would help with V-D absrobtion, you also need to balance out the mercury content these days found in seafood -so this leaves us needing a supplement.
