How much vitamin D? Vitamin D Council's recommendations

Since my recent post on problems related to vitamin D deficiency and excess I received several questions. I have also participated in several discussions in other blogs related to vitamin D in the past few days. There is a lot of consensus about vitamin D deficiency being a problem, but not much about vitamin D in excess being a problem as well. Some bloggers recommend a lot of supplementation, which may be dangerous because: (a) our body evolved to obtain most of its vitamin D from a combination of sunlight exposure and cholesterol, and thus body accumulation regulation mechanisms are not designed to deal with excessive oral supplementation; and (b) vitamin D, like many fat-soluble vitamins, accumulates in fat tissue over time, and is not easily eliminated by the body when in excess. The Vitamin D Council has the following general recommendation regarding supplementation: Take an average of 5,000 IU a day, year-round, if you have some sun exposure. If you have little, or no, sun exp...

Why dark chocolate is good for her heart

Listen up, men! On this Valentine's Day, why not surprise your special lady with chocolates that are healthier for her heart? Dark chocolate eaten in moderate amounts weekly is associated with improved cardiovascular fitness in women, research suggests. Scientists are only beginning to understand why dark chocolate is heart healthy, but a new study offers this explanation—its rich content of cocoa antioxidant compounds, called polyphenols, could enhance activity of special proteins called sterol regulatory element binding proteins (SREBPs), which are involved in cholesterol metabolism. These activated SREBPs then bind to genes on DNA (sterol regulatory element sequences) that boost liver production of another protein called apolipoprotein A1 (ApoA1), which is the major protein component of HDL "good" cholesterol. Correspondingly, cocoa polyphenols also decreased production of another protein in the liver called apolipoprotein B (ApoB), which is the major protein componen...

Are you a "Super Souler"?  That's how Oprah affectionately refers to those who watch her Super Soul series on Sunday nights.  Each week she interviews a different thinker, pastor, author, or person who seeks to have a deeper/more meaningful life experience.  She recently had Steven Pressfield on, the author of  The War of Art .  Have you read it?  It was a great conversation about how when we try to go higher or deeper in our lives (be it in our relationships, career, health, parenting, finances, etc.) we will naturally encounter things like resistance, fear, and self-doubt.  But, Steven says, that's when we know we're on the right path.  Two sentences very eloquently written in his book stood out: Whoa.  Is this a lightbulb moment for any of you?  As their conversation continued, Steven shared what I also believe to be true.   Once you commit, and you are on the path to living the life within (the path that resonates with your soul...
