On any given day, we have between 1,100 and 1,700 milligrams of cholesterol in our body. 25% of that comes from our diet, and 75% is produced inside of our bodies by the liver. Much of the cholesterol that’s found in food can’t be absorbed by our bodies, and most of the cholesterol in our gut was first synthesized in body cells and ended up in the gut via the liver and gall bladder. The body tightly regulates the amount of cholesterol in the blood by controlling internal production; when cholesterol intake in the diet goes down, the body makes more. When cholesterol intake in the diet goes up, the body makes less.
In 1975–1977, Elizabeth Blackburn, working as a postdoctoral fellow at Yale University with Joseph Gall, discovered the unusual nature of telomeres, with their simple repeated DNA sequences composing chromosome ends. Blackburn, Carol Greider, and Jack Szostak were awarded the 2009 Nobel Prize in Physiology or Medicine for the discovery of how chromosomes are protected by telomeres and the enzyme telomerase.
Nevertheless, in the 1970s there was no recognition that the telomere-shortening mechanism normally limits cells to a fixed number of divisions, and no animal study suggesting that this could be responsible for aging on the cellular level and sets a limit on lifespans.
Research, published in 2008 in the journal Archives of Internal Medicine, shows that those with the lowest vitamin D levels more than double their risk of dying from heart disease, stroke and other causes, compared with those with the highest vitamin D levels. The researchers cite “decreased outdoor activity” as one reason that people may become deficient in vitamin D.
Another recent study found an increased risk of heart attacks in men with low vitamin D levels, but that didn’t hold true for women. However, getting enough sun may help women prevent breast cancer. Canadian researchers compared 3,101 breast cancer victims with 3,471 healthy women without tumors.
Plateau. That dreaded word that you do not want to hear, let alone experience. Especially if you have been diligently exercising in an attempt to get fit or lose weight. We have all experienced a plateau at some time all of a sudden you stop losing weight or you just cant seem to run any faster. When you hit a plateau, don’t panic. It doesn’t necessarily mean you need to change-up everything or spend more time exercising.
There’s a reason you’re confused. Years ago, butter was a no-no. Vegetable-oil-based margarines surged in popularity as doctors began to understand the dangers of saturated fat. But the butter-versus-margarine debate is a slippery subject. Some margarines have unhealthy Tran’s fats, while others have confusing health claims. Meanwhile, some say butter is an “all-natural” choice.
