Most shark attacks occur less than 100 feet from the shore. More people are killed by bee stings and lightning than by shark attacks. Worldwide about 30 people die each year from shark attacks, which means a person has a one in 300 million chance of being killed by a shark. A shark attack most often occurs when a shark mistakes a person for a seal or other animal.
The new 2010 recommended daily allowance (RDA) is 600 IU for those 1-70 years of age and pregnant or breastfeeding women, and 800 IU for those over 71 years of age. An adequate blood level of vitamin D is 20 nanograms per milliliter, which can be achieved through daily skin exposure to sunlight.
And, women with insufficient vitamin D levels had 80% more abdominal fat than women with high levels of vitamin D. Once vitamin D is in the bloodstream, the kidneys activate it into the hormone 1,25-D. This is important because 1,25-D is the hormone that controls the growth of cells, including fat and cancer cells.
